Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer sheet 2.The Secret to Raising Smart Kids[A] I first began to investigate the basis of human motivation-and how people persevere after setbacks-as a psychology graduate student at Yale University in the 1960s. Animal experiments by psychologists at the University of Pennsylvania had shown that after repeated failures, most animals conclude that a situation is hopeless and beyond their control. After such an experience an animal often remains passive even when it can effect change-a state they called learned helplessness.[B]People can learn to be helpless, too. Why do some students give up when encounter difficulty, whereas others who are no more skilled continue to strive and learnOne answer, I soon discovered, lay in people’s beliefs about why they had failed.[C] In particular, attributing poor performance to a lack of ability depresses motivation more than does the belief that lack of effort is to blame. When I told a group of school children who displayed helpless behavior that a lack of effort led to their mistakes in math, they learned to keep trying when the problems got tough. Another group of helpless children who were simply rewarded for their success on easier problems did not improve their ability to solve harm math problems. These experiments indicated that a focus on effort can help resolve helplessness and generate success.[D] Later, I developed a broader theory of what separates the two general classes of learners-helpless versus mastery-oriented. I realized these different types of students not only explain their failures differently, but they also hold different “theories” of intelligence. The helpless ones believe intelligence is a fixed characteristic: you have only a certain amount, and that's that. I call this a "fixed mind-set(思维模式)."Mistakes crack their self-confidence because they attribute errors to a lack of ability, which they feel powerless to change. They avoid challenges because challenges make mistakes more likely. The mastery-orient children, on the other hand, think intelligence is not fixed and can be developed through education and hard work. Such children believe challenges are energizing rather than intimidating (令人生畏);they offer opportunities to learn. Students with such a growth mind-set were destined(注定)for great academic success and were quite likely to outperform their counterparts.[E] We validated these expectations in a study in which two other psychologists and I monitored 373 student for two years during the transition to junior high school, when the work gets more difficult and the grading more strict, to determine how their mind-sets might affect their math grades. At the beginning of seventh grade, we assessed the students' mind-sets by asking them to agree or disagree with statements such as "Your intelligence is something very basic about you that you can't really change." We then assessed their beliefs about other aspects of learning and looked to see what happened to their grades.[F] As predicted, the students with a growth mind-set felt that learning was more important goal than getting good grades. In addition, they held hard work in high regard, They understood that even geniuses have to work hard. Confronted by a setback such as a disappointing test grade, students with a growth mind-set said they would study harder or try a different strategy. The students who held a fixed mind-set, however, were concerned about looking smart with less regard for learning. They had negative views of effort, believing that having to work hard was a sign of low ability. They thought that a person with talent or intelligence did not need to work hard to do well. Attributing a bad grade to their own lack of ability, those with a fixed mind-set said that would study less in the future, try never to take that subject again and consider cheating on future tests.[G] Such different outlook had a dramatic impact on performance. At the start of junior high, the math achievement test scores of the students with a growth mind-set were comparable to the those of students who displayed a fixed mind-set. But as the workbecame more difficult, the students with a growth mind-set showed greater persistence. As a result, their math grades overtook those of the other students by the end of the first semester-and the gap between the two groups continued to widen during the two years we followed them.[H] A fixed mind-set can also hinder communication and progress in the workplace and discourage or ignore constructive criticism and advice. Research shows that managers who have a fixed mind-set are less likely to seek or welcome feedback from their employees than are managers with a growth mind-set.[I] How do we transmit a growth mind-set to our children One way is by telling stories about achievements that result from hard work. For instance, talking about mathematical geniusesWho were more or less born that way puts students in a fixed mind-set, but mathematicians who fell in love with math and developed amazing skills produce a growth mind-set.[J] In addition, parents and teachers can help children by providing explicit instruction regarding the mind as a learning machine, I designed an eight-session workshop for 91 students whose math grades were declining in their first year of junior high. Forty-eight of the students received instruction in study skills only, whereas the others attended a combination of study skills sessions and classes in which they learned about the growth mind-set and how to apply it to schoolwork. In the growth mind-set classes, students read and discussed an article entitled “You Can Grow Your Brain.” They were taught that the brain is like a muscle that gets stronger with use and that learning prompts thebrain to grow new connections. From such instruction, many students began to see themselves as agents of their own brain development. Despite being unaware that there were two types of instruction, teachers reported significant motivational changes in 27% of the children in the growth mind-set workshop as compared with only 9% of students in the control group.[K]Research is converging(汇聚)on the conclusion that great accomplishment and even genius is typically the result of years of passion and dedication and not something that flows naturally from a gift.author's experiment shows that students with a fixed mind-set believe having to work hard is an indication of low ability.on effort is effective in helping children overcome frustration and achieve success.can cultivate a growth mind-set in children by telling success stories that emphasize hard work love of learning.’ belief about the cause of their failure explains their attitude toward setbacks.t he author’s experiment, student with a growth mind-set showed greater perseverance in solving difficult math problems.author conducted an experiment to find out about the influence of students’ mind-sets on math learning.failing again and again, most animals give up hope.students about the brain as a learning machine is a good strategy to enhance their motivation for learning.with a fixed mind-set believe that one’s intelligence is unchangeable.the workplace, feedback may not be so welcome to managers with a fixed mind-set. Section CDirections：There are 2 passages in this section .Each passage is followed by some questions or unfinished statements. For each of them there are four choices maked A），B），C）and D）.You should decide on the best choice and mark the corresponding letter on Answer Sheet2 with a single line through the centre. Passage OneQuestions 46 to 50 are based on the following passage."Sugar, alcohol and tobacco," economist Adam Smith once wrote, "are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, and which are, therefore, extremely popular subjects of taxation."Two and a half centuries on, most countries impose some sort of tax on alcohol and tobacco. With surging obesity levels putting increasing strain on public health systems, governments around the world have begun to toy with the idea of taxing sugar as well.Whether such taxes work is a matter of debate. A preliminary review of Mexico's taxation found a fall in purchases of taxed drinks as well as a rise in sales if untaxed and healthier drinks. By contrast, a Danish tax on foods high in fats was abandoned a year after its introduction, amid claims that consumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattier fare.The food industry has, in general, been firmly opposed to such direct government action. Nonetheless, the renewed focus on waistlines means that industry groups are under pressure to demonstrate their products are healthy as well as tasty.Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufactures have cut the amount of sugar in their beverages.Many of the reductions over the past 30 years have been achieved either by reducing the amount of sugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however.Some companies have been investing money in a more ambitious undertaking: learning how to adjust the fundamental make-up of the food they sell. For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.While reformulating recipes(配方)is one way to improve public health, it should be part of a multi-sided approach. The key is to remember thatthere is not just one solution. To deal with obesity, a mixture of approaches-including reformulation, taxation and adjusting portion sizes-will be needed. There is no silver bullet.46. What did Adam Smith say about sugar, alcohol and tobacco?A)They were profitable to manufacture.B)They were in ever-increasing demand.C)They were subject to taxation almost everywhere.D)They were no longer considered necessities of life.have many countries started to consider taxing sugar?A)They are under growing pressures to balance their national budgets.B)They find it ever harder to cope with sugar-induced health problems.C)They practice of taxing alcohol and tobacco has proved both popular and profitable.D)The sugar industry is overtaking alcohol and tobacco business in generating profits.do we learn about Danish taxation on fat-rich foods?A)It did not work out as well as was expected.B)It gave rise to a lot of problems on the border.C)It could not succeed without German cooperation.D)It met with firm opposition from the food industry.is the more recent effort by food companies to make foods and drinks both healthy and tasty?A)Replacing sugar or salt with alternative ingredients.B)Setting a limit on the amount of sugar or salt in their products.C)Investing in research to find ways to adapt to consumers' needs.D)Adjusting the physical composition of their products.does the author mean by saying, at the end of the passage, "There is no silver bullet"(Line 4, Para 7)A)There is no single easy quick solution to the problem.B)There is no hope of success without public cooperation.C)There is on hurry in finding ways to solve the obesity problem.D)There is no effective way to reduce people's sugar consumption.Passage TwoQuestions 51 to 55 are based on the following passage.You may have heard some of the fashion industry horror stories: models eating tissues or cotton balls to hold off hunger, and models collapsing from hunger-induced heart attacks just seconds after they step off the runway.Excessively skinny models have been a point of controversy for decades, and two researchers say a model's body mass should be a workspace health and safety issue. In an editorial released Monday in the American Journal of Public Health, Katherine Record and Bryn Austin made their case for government regulation of the fashion industry.The average international runway model has a body mass index (BMI) under 16-low enough to indicate starvation by the World Health Organization's standard. And Record and Austin are worried not just about the models themselves, but about the vast number of girls and women their images influence."Especially girls and tens", says Record. "Seventy percent of girls aged 10 to 18 report that they define perfect body image based on what they see in magazines." That's especially worrying, she says, given that anorexia(厌食症)results in more deaths than does any other mental illness, according to the National Institute of Mental Health.It's commonly known that certain diseases are linked with occupations like lung disease in coal miners. Professional fashion models are particularly vulnerable to eating disorders resulting from occupational demands to maintain extreme thinness.Record's suggestion is to prohibit agents from hiring models with a BMI below 18.In April, France passed a law setting lower limits for a model's weight. Agents and fashion houses who hire models with BMI under 18 could pay $82,000 in fines and spend up to 6 months in jail. Regulating the fashion industry in the United States won't be easy, Record says. But with the new rules in France, . support could make a difference. "A designer can't survive without participating in Paris Fashion Week", she says, adding, "Our argument is that the same would be true of New York Fashion Week."do Record and Austin say about fashion models' body mass?A)It has caused needless controversy.B)It is focus of the modeling business.C)It is but a matter of personal taste.D)It affects models' health and safety.are Record and Austin advocating in the Monday editorial?A)A change in the public's view of female beauty.B)Government legislation about models' weight.C)Elimination of forced weight loss by models.D)Prohibition of models eating non-food stuff.are Record and Austin worried about the low body mass index of models?A)It contributes to many mental illnesses.B)It defines the future of the fashion industry.C)It has great influence on numerous girls and women.D)It keeps many otherwise qualified women off the runaway.54. What do we learn about France's fashion industry?A)It has difficulty hiring models.B)It has now a new law to follow.C)It allows girls under 18 on the runway.D)It has overtaken that of the United States.55. What does Record expect of New York Fashion Week?A)It will create a completely new set of rules.B)It will do better than Paris Fashion Week.C)It will differ from Paris Fashion Week.D)It will have models with a higher BMI.Part IV Translation （30 minutes）Directions：For this part， you are allowed 30minutes to translate a passage from Chinese into English .You should write your answer on Answer Sheet 2.在中国文化中，黄颜色是一种很重要的颜色，因为它具有独特的象征意义。

Not much. Rather than offer evidence for（28）brains as “male” or “female,” research shows that brains fall into a wide range, with most people falling right in the middle.Daphna Joel, who led the study, said her research found that while there are some gender-based（29）, many different types of brain can’t always be distinguished by gender.While the “average” male and “average” female brains were（30）different, you couldn’t tell it by looking at individual brain scans. Only a small（31）of people had “all-male” or “all-female” characteristics.Larry Cahill, an American neuroscientist (神经科学家),said the study is an important addition to a growing body of research questioning（32）beliefs about gender and brain function. But he cautioned against concluding from this study that all brains are the same,（33）of gender.“There’s a mountain of evidence（34）the importance of sex influences at all levels of brain function,” he told The Seattle Ti mes.If anything, he said, the study（35）that gender plays a very important role in the brain “even when we are not clear exactly how.”A) abnormal B) applied C) briefly D) categorizingE) challenges F) figure G) percentage H) provingI) regardless J) searched K) similarities L) slightlyM) suggests N) tastes O) traditionalSection BDirections: In this section, you are going to read a passage with ten statements attached to it.

Answer the questions by marking the corresponding letter on Answer Sheet 2.Can Burglars Jam Your Wireless Security System?[A]Any product that promises to protect your home deserves careful examination. So it i sn’t surprising that you’ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.[B]The most likely type of burglary (入室盗窃) by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted roughly two-thirds of all household burglaries in the US in 2013.The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal using technical means to bypass a security system are so small that the FBI doesn’t even track those statistics.[C]One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar (入室盗贼) might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming? With the right device tuned to the right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?[D]Jamming concerns are nothing new, and they’re not u nique to security systems. Any device that’s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, let’s say you wanted to “jam” a conversation between two people—all you’d need to do is yell in the listener’s ear.[E] Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimal Googling. They will, however, need so know wha t system they’re looking for. If you have a sign in your yard declaring what setup you use, that’d point them in the right direction, though at that point, we’re talking about a highly targeted, semi-sophisticated attack, and not the sort forced-entry atta ck that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.[F] Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editor’s Choice distinction, utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks. When the system thinks it’s being jammed, it’ll notify you via push alert(推送警报).From the re, it’s up to you to sound the alarm manually.[G] SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measures to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it’s possible with the right equipment. However, we also verified that SimpliSafe’santi-jamming system works. It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not in detected them.[H]We like the unique nature of that software. It means that a thief likely wouldn’t be able to Google how the system works, then figure out a way around it. Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly from system to system, which means there wouldn’t be a universal magic formula for cracking it. Other systems also seem confident on the subject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t an y documented cases of successful jam attack since the company began offering wireless security sensors in the 1980s.[I] Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wi reless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff?[J] Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at ni ght and while you’re away. So the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or openeddoor would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does now have access to.[K]At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.36. It is possible for burglars to make jamming attacks with the necessary equipmentand skill.37. Interfering with a wireless security system is similar to interfering with aconversation.38. A burglar has to continuously jam the wireless security device to avoid triggeringthe alarm, both inside and outside the house.39. SimpliSafe provides devices that are able to distinguish incidental radiointerference from targeted jamming attacks.40. Only a very small proportion of burglaries are committed by technical means.41. It is difficult to crack SimpliSafe as its system keeps changing.42. Wireless devices will transmit signals so as to activate the alarm once somethingwrong is detected.43. Different measures should be taken to protect one’s home from burglary inaddition to the wireless security system.44. SimpliSafe’s device can send a warning to the house owner’s cellphone.45. Burglars can easily get a security device’s frequency by Internet search.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.As a person who writes about food and drink for a living. I couldn’t tell you the first thing about Bill Perry or whether the beers he sells are that great. But I can tell you that I like this guy. That’s because he plans to ban tipping in favor of paying his servers an actual living wage.I hate tipping.I hate it because it’s an obligation disguised as an option. I hate it for thepost-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have a voice in how much money your server makes. No matter how the math works out, you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true, we would all be slipping a few 100-dollar bills to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers of humanity that they are, are catching on to this; in one poll, a full 30% said they didn’t believe the job they did had any impact on the tips they received.So come on, folks: get on board with ditching the outdated tip system. Pay a little more upfront for your beer or burger. Support Bill Perry’s pub, and any other bar or restaurant that doesn’t ask you to do drunken math.46. What can we learn about Bill Perry from the passage?A) He runs a pub that serves excellent beer.B) He intends to get rid of the tipping practice.C) He gives his staff a considerable sum for tips.D) He lives comfortably without getting any tips.47. What is the main reason why the author hates tipping?A) It sets a bad example for other industries.B) It adds to the burden of ordinary customers.C) It forces the customer to compensate the waiter.D) It poses a great challenge for customers to do math.48. Why do many people love tipping according to the author?A) They help improve the quality of the restaurants they dine in.B) They believe waiters deserve such rewards for good service.C) They want to preserve a wonderful tradition of the industry.D) They can have some say in how much their servers earn.49. What have some waiters come to realize according to a survey?A) Service quality has little effect on tip size.B) It is in human mature to try to save on tips.C) Tips make it more difficult to please customers.D) Tips benefit the boss rather that the employees.50. What does the author argue for in the passage?A) Restaurants should calculate the tips for customers.B) Customers should pay more tips to help improve service.C) Waiters deserve better than just relying on tips for a living.D) Waiters should be paid by employers instead of customers.Passage TwoQuestions 51 to 55 are based on the following passage.In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened?Some experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more mo ney in their pockets when they’re paying less at the pump. They spend that money on other things, which stimulates the economy.The biggest gains go to countries that import most of their oil like China, Japan, and India, But doesn’t the extra money in the pockets of those countries’ consumers mean an equal loss in oil producing countries, cancelling out the gains? Not necessarily, says economic researcher Sara Johnson. “Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies(补贴) for their consumers.”But not all oil producers have big reserves, In Venezuela, collapsing oil prices have sent its economy into free-fall.Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly because oil-producing nations can’t afford to import as much as they used to.Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy.Consumers, in the U.S. at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasolinesubsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.51. What does the author mainly discuss in the passage?A) The reasons behind the plunge of oil prices.B) Possible ways to stimulate the global economy.C) The impact of cheap oil on global economic growth.D) The effect of falling oil prices on consumer spending.52. Why do some experts believe cheap oil will stimulate the global economy?A) Manufacturers can produce consumer goods at a much lower cost.B) Lower oil prices have always given a big boost to the global economy.C) Oil prices may rise or fall but economic laws are not subject to change.D) Consumers will spend their saving from cheap oil on other commodities.53. What happens in many oil-exporting countries when oil prices go down?A) They suspend import of necessities from overseas.B) They reduce production drastically to boost oil prices.C) They use their money reserves to back up consumption.D) They try to stop their economy from going into free-fall.54. How does Carl Weinberg view the current oil price plunge?A) It is one that has seen no parallel in economic history.B) Its negative effects more than cancel out its positive effects.C) It still has a chance to give rise to a boom in the global economy.D) Its effects on the global economy go against existing economic laws.55. Why haven’t falling oil prices boosted the global economy as they did before?A) People are not spending all the money they save on gas.B) The global economy is likely to undergo another recession.C) Oil importers account for a larger portion of the global economy.D) People the world over are afraid of a further plunge in oil prices.Part IV Translation (30minutes)Directions: For this part,you are allowed 30minutes to transtate a passage from Chinese into English.You should write your answer on Answer Sheet 2.在中国文化中，红色通常象征着好运、长寿和幸福，在春节和其他喜庆场合，红色到处可见。

You should write at least 120 words but nomore than 180 words.Much controversy has been aroused about whether the students should find a job or start their own business after graduation.Taking a look around,we can find that some graduates bustle around job markets,while others choose to run a shop on TMall. However, I prefer the former choice.From my perspective, there are good reasons to find a job in the first severalyears after their graduation.First and foremost, if a graduate intends to accumulate working experience and learn from the seniors, it is advisable for him to find ajob. It is an undeniable fact that the theoretical knowledge will provide thegraduates with the ability to consider things comprehensively,however,only under the integration with practice can the rigid knowledge be useful for their futuredevelopment. Inevitably, doing something small is the premise of undertakingsomething great. Take Jack Ma, the founder of Alibaba and taobao, for example. Healso finds some jobs before establishing his own career,laying a solid foundation for his later success.Consequently,it is of great necessity to find a job after graduation.I firmly believe that it will continue to bring about more returns to our life and future.Part II Listening Comprehension (25 minutes)Section ADirections: In this section, you will hear three news reports.

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose aparagraph more than once. Each paragraph is marked with a letter. Answer thequestions by marking the corresponding letter on Answer Sheet 2.Can Burglars Jam Your Wireless Security System?A)Any product that promises to protect your home deserves careful examination. So it isn't surprising that you ’ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.B)The most likely type of burglary(入室盗窃 )by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. Accordingto the FBI, crimes like these accounted for roughly two-thirds of all householdburglaries in the US in 2013. The wide majority of the rest were illegal, unforcedentries that resulted from something like a window being left open. The odds ofcriminal using technical means to bypass a security system are so small that theFBI doesn ’ t even track those statistics.C)One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups,the fear is that a burglar(入室盗贼 )might be able to shut your system down simplyby cutting the right cable.With a wireless setup,you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If theydetect something wrong while the system is armed, they ’ ll transmit a wireless alert signal to a base station that will then raise the alarm.That approach will eliminate most cord-cutting concerns —but what about their wireless equivalent,jamming? With the right device tuned to the right frequency,what ’ s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?D)Jamming concerns are nothing new, and they ’ re not unique to security systems. Any device that ’ s built to receive a wireless signal at a specific frequency canbe overwhelmed by a stronger signal coming in on the same frequency.For comparison, let ’ s say you wanted to“ jam ” a conversation between two people — all you’ d need to do is yell in the listener’ s ear.E)Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimalGoogling. They will,however,need to know what system they ’ re looking for. If you have a sign in your yard declaring what setup you use, that’ d point them in theright direction, though at that point, we’ re talking about a highly targeted,semi-sophisticated attack, and not the sort of forced-entry attack that makes upthe majority of burglaries.It’ s easier to find and acquire jamming equipment for some frequencies than it is for others.F)Wireless security providers will often take steps to help combat the threatof jamming attacks.SimpliSafe,winner of our Editors ’ Choice distinction,utilizesa special system that’ s capable of separating incidental RF interference fromtargeted jamming attacks.When the system thinks it’ s being jammed, it ’ ll notify you via push alert( 推送警报 ).From there,it’s up to you to sound the alarm manually.G)SimpliSafe was singled out in one recent article on jamming, complete witha video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measure to contain the RF interference to ourtest lab, we tested the attack out for ourselves, and were able to verify that itis possible with the right equipment. However, we also verified that SimpliSafe’s anti-jamming system works. It caught us in the act,sent an alert to my smartphone, and also listed our RF interference on the system ’ s event log. The team behind the article and video in question make no mention of the system, or whether or not itdetected them.H)We like the unique nature of that software. It means that a thief likely wouldn ’t be able to Google how the system works, then figure out a way around itEven if they could, SimpliSafe claims that its system is always evolving, and thatit varies slightly from system to system, which means there wouldn ’ t be a universal magic formula for cracking it Other systems also seem confident on the subject ofjamming.

As said before, with the rightequipment and the right know-how,it’ s possible to jam any wireless transmission. But how probable is it that someone will successfully jam their way into your homeand steal your stuff?J)Let ’ s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need totarget your home, specifically. Then, he’s going to need to know the technicaldetails of your system and acquire the specific equipment necessary for jamming your specific setup.

However, he’ll need to do so without tripping theanti-jamming system, the details of which he almost certainly does not have access to.K) At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries.They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like soundlocks and proper exterior lighting at night.

One reason is that more countries are big oil producers now, so the nations suffering from the prices drop accountfor a larger share of the global economy.Consumers, in the U.S. at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is stillfresh in their mind. And a number of oil-producing countries are trimming theirgasoline subsidies and raising taxes, so the net savings for global consumers isnot as big as the oil price plunge might suggest.51.What does the author mainly discuss in the passage?A)The reasons behind the plunge of oil prices.B)Possible ways to stimulate the global economy.C)The impact of cheap oil on global economic growth.D)The effect of falling oil prices on consumer spending.【答案】 C52.Why do some experts believe cheap oil will stimulate the global economy?A)Manufacturers can produce consumer goods at a much lower cost.B)Lower oil prices have always given a big boost to the global economy.C)Oil prices may rise or fall but economic laws are not subject to change.D)Consumers will spend their savings from cheap oil on other commodities.【答案】 D53.What happens in many oil-exporting countries when oil prices go down?A)They suspend import of necessities from overseas.B)They reduce production drastically to boost oil prices.C)They use their money reserves to back up consumption.D)They try to stop their economy from going into free-fall.【答案】 C54.How does Carl Weinberg view the current oil price plunge?A)It is one that has seen no parallel in economic history.B)Its negative effects more than cancel out its positive effects.C)It still has a chance to give rise to a boom in the global economy.D)Its effects on the global economy go against existing economic laws.【答案】 B55.Why haven’t falling oil prices boosted the global economy as they did before?A)People are not spending all the money they save on gas.B)The global economy is likely to undergo another recession.C)Oil importers account for a larger portion of the global economy.D)People the world over are afraid of a further plunge in oil prices.【答案】 APart IV Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passagefrom Chinese into English.

Write an essay to explain the reasons for your choice. You should write at least 120 words but no more than 180 words.参考范文：Upon graduation, virtually all college students will confront the problem of the career choice，which is truly a tough choice. Students' opinions differ greatly on this issue. Some hold that priority should be given to take a job, but others take the attitude that going to a graduate school is the most critical factor influencing their future career choices.As to myself, I prefer the latter view. A higher educational background exerts a tremendous fascination on a great number of people, with no exception to me. This phenomenon that the graduates have difficulties in finding job after their graduation can easily be found anywhere in our daily life, especially on campus. On the one hand, with the improved high education of Chinese college students which directly brought the result that there are more and more graduates every year. On the contrary, job vac ancies don’t increase that fast. More people, less food, which is the exact description of the hard condition. On the other hand, more and more people go on to pursue their master and doctor degree; more and more Chinese oversea students come back to China to hunt better working chances. It is sure that the competition is more and more fierce.Therefore, it is high time that we took effective measures to improve our own competitiveness. That is the secret of success in the future employment market after our graduation.Part ⅢReading Section A(卷二)The ocean is heating up.

Answer the questions by marking the corresponding letter on Answer sheet 2.The Secret to Raising Smart Kids[A] I first began to investigate the basis of human motivation-and how people persevere after setbacks-as a psychology graduate student at Yale University in the 1960s. Animal experiments by psychologists at the University of Pennsylvania had shown that after repeated failures, most animals conclude that a situation is hopeless and beyond their control. After such an experience an animal often remains passive even when it can effect change-a state they called learned helplessness.[B]People can learn to be helpless, too. Why do some students give up when encounter difficulty, whereas others who are no more skilled continue to strive and learn? One answer, I soon discovered, lay in people’s beliefs about why they had failed.[C] In particular, attributing poor performance to a lack of ability depresses motivation more than does the belief that lack of effort is to blame. When I told a group of school children who displayed helpless behavior that a lack of effort led to their mistakes in math, they learned to keep trying when the problems got tough. Another group of helpless children who were simply rewarded for their success on easier problems did not improve their ability to solve harm math problems. These experiments indicated that a focus on effort can help resolve helplessness and generate success.[D]Later, I developed a broader theory of what separates the two general classes of learners-helpless versus mastery-oriented. I realized these different types of students not only explain their failures differently, but they also hold different “theories”of intelligence. The helpless ones believe intelligence is a fixed characteristic: you have only a certain amount, and that's that. I call this a "fixed mind-set(思维模式)."Mistakes crack their self-confidence because they attribute errors to a lack of ability, which they feel powerless to change. They avoid challenges because challenges make mistakes more likely. The mastery-orient children, on the other hand, think intelligence is not fixed and can be developed through education and hard work. Such children believe challenges are energizing rather than intimidating (令人生畏);they offer opportunities to learn. Students with such a growth mind-set were destined(注定)for great academic success and were quite likely to outperform their counterparts.[E]We validated these expectations in a study in which two other psychologists and I monitored 373 student for two years during the transition to junior high school, when the work gets more difficult and the grading more strict, to determine how their mind-sets might affect their math grades. At the beginning of seventh grade, we assessed the students' mind-sets by asking them to agree or disagree with statements such as "Your intelligence issomething very basic about you that you can't really change." We then assessed their beliefs about other aspects of learning and looked to see what happened to their grades.[F] As predicted, the students with a growth mind-set felt that learning was more important goal than getting good grades. In addition, they held hard work in high regard, They understood that even geniuses have to work hard. Confronted by a setback such as a disappointing test grade, students with a growth mind-set said they would study harder or try a different strategy. The students who held a fixed mind-set, however, were concerned about looking smart with less regard for learning. They had negative views of effort, believing that having to work hard was a sign of low ability. They thought that a person with talent or intelligence did not need to work hard to do well. Attributing a bad grade to their own lack of ability, those with a fixed mind-set said that would study less in the future, try never to take that subject again and consider cheating on future tests.[G] Such different outlook had a dramatic impact on performance. At the start of junior high, the math achievement test scores of the students with a growth mind-set were comparable to the those of students who displayed a fixed mind-set. But as the work became more difficult, the students with a growth mind-set showed greater persistence. As a result, their math grades overtook those of the other students by the end of the first semester-and the gap between the two groups continued to widen during the two years we followed them.[H] A fixed mind-set can also hinder communication and progress in the workplace and discourage or ignore constructive criticism and advice. Research shows that managers who have a fixed mind-set are less likely to seek or welcome feedback from their employees than are managers with a growth mind-set.[I] How do we transmit a growth mind-set to our children? One way is by telling stories about achievements that result from hard work. For instance, talking about mathematical geniuses Who were more or less born that way puts students in a fixed mind-set, but mathematicians who fell in love with math and developed amazing skills produce a growth mind-set.[J] In addition, parents and teachers can help children by providing explicit instruction regarding the mind as a learning machine, I designed an eight-session workshop for 91 students whose math grades were declining in their first year of junior high. Forty-eight of the students received instruction in study skills only, whereas the others attended a combination of study skills sessions and classes in which they learned about the growth mind-set and how to apply it to schoolwork. In the growth mind-set classes, students read and discussed an article entitled “You Can Grow Your Brain.” They were taught that the brain is like a muscle that gets stronger with use and that learning prompts the brain to grow new connections. From such instruction, many students began to see themselves as agents of their own brain development. Despite being unaware that there were two types of instruction, teachers reported significant motivational changes in 27% of the children in the growth mind-set workshop as compared with only 9% of students in the control group.[K]Research is converging(汇聚)on the conclusion that great accomplishment and even genius is typically the result of years of passion and dedication and not something that flows naturally from a gift.36.The author's experiment shows that students with a fixed mind-set believe having to work hard is an indication of low ability.37.Focusing on effort is effective in helping children overcome frustration and achievesuccess.38.We can cultivate a growth mind-set in children by telling success stories that emphasize hard work love of learning.39.Students’ belief about the cause of their failure explains their attitude toward setbacks.40.In the author’s experiment, student with a growth mind-set showed greater perseverance in solving difficult math problems.41.The author conducted an experiment to find out about the influence of students’ mind-sets on math learning.42.After failing again and again, most animals give up hope.rming students about the brain as a learning machine is a good strategy to enhance their motivation for learning.44.People with a fixed mind-set believe that one’s intelligence is unchangeable.45.In the workplace, feedback may not be so welcome to managers with a fixed mind-set. Section CDirections：There are 2 passages in this section .Each passage is followed by some questions or unfinished statements. For each of them there are four choices maked A），B），C）and D）.You should decide on the best choice and mark the corresponding letter on Answer Sheet2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage."Sugar, alcohol and tobacco," economist Adam Smith once wrote, "are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, and which are, therefore, extremely popular subjects of taxation."Two and a half centuries on, most countries impose some sort of tax on alcohol and tobacco. With surging obesity levels putting increasing strain on public health systems, governments around the world have begun to toy with the idea of taxing sugar as well.Whether such taxes work is a matter of debate. A preliminary review of Mexico's taxation found a fall in purchases of taxed drinks as well as a rise in sales if untaxed and healthier drinks. By contrast, a Danish tax on foods high in fats was abandoned a year after its introduction, amid claims that consumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattier fare.The food industry has, in general, been firmly opposed to such direct government action. Nonetheless, the renewed focus on waistlines means that industry groups are under pressure to demonstrate their products are healthy as well as tasty.Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufactures have cut the amount of sugar in their beverages.Many of the reductions over the past 30 years have been achieved either by reducing the amount of sugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however.Some companies have been investing money in a more ambitious undertaking: learning how to adjust the fundamental make-up of the food they sell. For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.While reformulating recipes(配方)is one way to improve public health, it should be partof a multi-sided approach. The key is to remember thatthere is not just one solution. To deal with obesity, a mixture of approaches-including reformulation, taxation and adjusting portion sizes-will be needed. There is no silver bullet.46. What did Adam Smith say about sugar, alcohol and tobacco?A)They were profitable to manufacture.B)They were in ever-increasing demand.C)They were subject to taxation almost everywhere.D)They were no longer considered necessities of life.47.Why have many countries started to consider taxing sugar?A)They are under growing pressures to balance their national budgets.B)They find it ever harder to cope with sugar-induced health problems.C)They practice of taxing alcohol and tobacco has proved both popular and profitable.D)The sugar industry is overtaking alcohol and tobacco business in generating profits.48.What do we learn about Danish taxation on fat-rich foods?A)It did not work out as well as was expected.B)It gave rise to a lot of problems on the border.C)It could not succeed without German cooperation.D)It met with firm opposition from the food industry.49.What is the more recent effort by food companies to make foods and drinks both healthy and tasty?A)Replacing sugar or salt with alternative ingredients.B)Setting a limit on the amount of sugar or salt in their products.C)Investing in research to find ways to adapt to consumers' needs.D)Adjusting the physical composition of their products.50.What does the author mean by saying, at the end of the passage, "There is no silver bullet"(Line 4, Para 7)?A)There is no single easy quick solution to the problem.B)There is no hope of success without public cooperation.C)There is on hurry in finding ways to solve the obesity problem.D)There is no effective way to reduce people's sugar consumption.Passage TwoQuestions 51 to 55 are based on the following passage.You may have heard some of the fashion industry horror stories: models eating tissues or cotton balls to hold off hunger, and models collapsing from hunger-induced heart attacks just seconds after they step off the runway.Excessively skinny models have been a point of controversy for decades, and two researchers say a model's body mass should be a workspace health and safety issue. In an editorial released Monday in the American Journal of Public Health, Katherine Record and Bryn Austin made their case for government regulation of the fashion industry.The average international runway model has a body mass index (BMI) under 16-low enough to indicate starvation by the World Health Organization's standard. And Record and Austin are worried not just about the models themselves, but about the vast number of girls and women their images influence."Especially girls and tens", says Record. "Seventy percent of girls aged 10 to 18 reportthat they define perfect body image based on what they see in magazines." That's especially worrying, she says, given that anorexia(厌食症)results in more deaths than does any other mental illness, according to the National Institute of Mental Health.It's commonly known that certain diseases are linked with occupations like lung disease in coal miners. Professional fashion models are particularly vulnerable to eating disorders resulting from occupational demands to maintain extreme thinness.Record's suggestion is to prohibit agents from hiring models with a BMI below 18.In April, France passed a law setting lower limits for a model's weight. Agents and fashion houses who hire models with BMI under 18 could pay $82,000 in fines and spend up to 6 months in jail. Regulating the fashion industry in the United States won't be easy, Record says. But with the new rules in France, U.S. support could make a difference. "A designer can't survive without participating in Paris Fashion Week", she says, adding, "Our argument is that the same would be true of New York Fashion Week."51.What do Record and Austin say about fashion models' body mass?A)It has caused needless controversy.B)It is focus of the modeling business.C)It is but a matter of personal taste.D)It affects models' health and safety.52.What are Record and Austin advocating in the Monday editorial?A)A change in the public's view of female beauty.B)Government legislation about models' weight.C)Elimination of forced weight loss by models.D)Prohibition of models eating non-food stuff.53.Why are Record and Austin worried about the low body mass index of models?A)It contributes to many mental illnesses.B)It defines the future of the fashion industry.C)It has great influence on numerous girls and women.D)It keeps many otherwise qualified women off the runaway.54. What do we learn about France's fashion industry?A)It has difficulty hiring models.B)It has now a new law to follow.C)It allows girls under 18 on the runway.D)It has overtaken that of the United States.55. What does Record expect of New York Fashion Week?A)It will create a completely new set of rules.B)It will do better than Paris Fashion Week.C)It will differ from Paris Fashion Week.D)It will have models with a higher BMI.Part IV Translation （30 minutes）Directions：For this part，you are allowed 30minutes to translate a passage from Chinese into English .You should write your answer on Answer Sheet 2.在中国文化中，黄颜色是一种很重要的颜色，因为它具有独特的象征意义。

2016年12月大学英语四级考试真题（第2套）参考答案Part IV TranslationThe color yellow is of great importance in Chinese culture, because of its distinctive symbolic meaning. It stood for the ruler’s power and authority in feudal society. The color was exclusively used by the emperors then: all the royal palaces were painted yellow and the dragon robes were always yellow. The civilians, however, were banned from wearing yellow clothes. The color yellow is also a sign of harvest in China. When the crops ripen in autumn, the fields will grow golden-yellow and people will cheerfully celebrate the harvest.Part II Listening Comprehension听力原文Section AQuestions 1 and 2 are based on the news report you have just heard.New York State plans to shut off the thundering waters of Niagara Falls—again. At least, the American side of the falls. This "once in a lifetime" event actually may take place twice in some folks' lives. The New York State parks system wants to turn off the falls on the American side sometime in the next two to three years to replace two 115-year-old stone bridges that allow pedestrians, park vehicles and utilities access to Goat Island.The American side of the falls were shut off in 1969 to study the buildup of rock at the base of the falls. When that happened, people came from all over the world to see the falls turned off.People are curious by nature. They want to see what's underneath. In fact, those who first came to have a look did see something. They found millions of coins on the bottom.1. Why does New York State want to turn off Niagara Falls?2. What did people find when Niagara Falls were shut off in 1969?Questions 3 and 4 are based on the news report you have just heard.The Tunisian government said Monday that 45 people have been killed after gunmen attacked a town near the border with Libya.The Interior and Defense ministries said that the Tunisian government has closed its two border crossings with Libya because of the attack.The Tunisian military has sent reinforcements and helicopters to the area, and authorities have been hunting several attackers who were still at large.The violence came amid increasing international concern about Islamic State extremists in Libya. Officials of the Tunisian government are especially worried after dozens of tourists were killed in the attacks in Tunisia last year.Defense Minister Farhat Horchani said last week that German and American security experts were expected to come to help Tunisia devise a new electronic video supervision system on its border with Libya.Tunisia was targeted last year by three attacks that left 70 people dead and were claimed by Islamic State.3. What did the Tunisian government do after the gunmen's attack?4. What were German and American security experts expected to do in Tunisia?Questions 5 to 7 are based on the news report you have just heard.Three university students in Santiago, Chile, have developed a plant-powered device to charge their mobile phones.The three engineering students got the idea for the device while sitting in their school's courtyard. Their invention is a small biological circuit they call E-Kaia. It captures the energy which plants produce during photosynthesis — a process of converting sunlight into energy.A plant uses only a small part of the energy produced by that process. The rest goes into the soil. E-Kaia collects that energy. The device plugs into the ground and then into a mobile phone.The E-Kaia solved two problems for the engineering students. They needed an idea for a class project. They also needed an outlet to plug in their phones.One of the student inventors, Camila Rupcich, says the device changes the energy released from the plant into low-level power to charge phones.The E-Kaia is able to fully recharge a mobile phone in less than two hours.5. What did the three university students invent?6. When did they get the idea for the invention?7. What does the speaker say about the invention?Section BQuestions 8 to 11 are based on the conversation you have just heard.M: Good morning. What can I do for you?W: Good morning. Could I talk to Jeffry Harding please?M: Speaking.W: Hello, Jeff. It's Helen. I got your message on the answering machine. What's the problem? M: Oh, Helen. Well, it's the Grimsby plant again, I'm afraid. The robots on Line 3 have gone wrong. And the line is at a standstill.W: Can't you replace them with the stand-ins?M: I'm afraid not. The stand-ins are already in use on Line 6. And the ones from Line 6 are being serviced.W: When did this happen, Jeff?M: Well, they've been making a low continuous sound for a day or two. But they finally went dead at 2:30 this afternoon.W: I see. What did you do? Have you tried the whole plant?M: Not yet, Helen. I thought I'd better get your OK first.W: OK. Get on the phone to Tom, and try to get their stand-ins over tonight. We have to be back at full capacity tomorrow morning. Is it a major job to repair our robots?M: About a week. That's what the maintenance engineer says.W: Right. Well, if you can get the ones from Tom, please ask Tom to inform Sheffield that he may need their stand-ins in case of emergency during the next week.M: OK. Thank you very much, Helen.W: You are most welcome.M: Sorry to spoil your day off.W: It doesn't matter.8. What did the man do before the telephone conversation?9. What does the man say about line 3 in the Grimsby plant?10. What is the man's purpose in calling the woman?11. Where is the woman at the time of the conversation?Questions 12 to 15 are based on the conversation you have just heard.W: This is Kerry Burke from New York Daily News. I'm speaking to Delroy Simmonds, an unemployed Brooklyn man who missed a job interview Tuesday for the best of reasons: He wassaving the life of a 9-month-old boy who was blown into the path of an oncoming subway train by a high wind.M: Everybody is making me out to be some sort of superhero. I'm just an ordinary person, and a father of two. Anybody in that situation would have done what I did.W: You were going to an interview when the incident occurred, right?M: Yes, I was on my way to apply for a maintenance position. I've been looking for a job for a year and more. I'm looking for something to support my family.W: Tell us what happened at the station.M: There was a strong wind. It had to be 30 to 40 miles an hour. There was a woman with four kids. One was in a pushchair. The wind blew the baby onto the tracks.W: Witnesses said people were looking on in horror as the child's mother, identified by sources as Maria Zamara, stood frozen in shock. In the distance, people could see the train rounding a bend, headed into the station. I guess you were not aware of any of these, right?M: No. I just jumped down and grabbed the baby. The train was coming around the corner as I lifted the baby from the tracks. I really wasn't thinking.W: What an amazing story. Thank you very much.12. What did Kerry Burke from New York Daily News say about the man?13. What do we learn about the man from the conversation?14. What caused the incident?15. How did the mother react when the incident occurred?Section CQuestions 16 to 18 are based on the passage you have just heard.There's one sound that gets a big reaction from kids on a hot day, the sound of an ice-cream truck.Maria McCartney has been in the mobile ice-cream business since 2005."When I was a little girl, I saw an ice-cream truck and knew I wanted to have one someday," McCartney said.During the hot days of summer, Maria and her daughter drive an ice-cream truck through neighborhoods and parks in Billings.It's not about making money for this former elementary school teacher. Rather, she wants to preserve the tradition of the neighborhood ice-cream truck."Truly my favorite part is to see the kids jumping up and down and they just get so excited. It's great to build a memory for them too. There’re not a lot of these ice-cream trucks around anymore. The parents come out barefoot and screaming, ready to buy ice-cream; they remember when they were kids and they saw a truck," she said.While the treats may be ice cold, Maria has a warm heart for little faces. Her truck features a donation bucket for kids who don't have money for ice-cream."When there are three kids and only two of them have money, I always make sure the third one gets something because I can't drive away and have that third one not have something," she said.16. What does the speaker say about Maria McCartney?17. Why does Maria go into the mobile ice-cream business?18. Why does Maria put a donation bucket in her truck?Questions 19 to 21 are based on the passage you have just heard.We know we have to pay for what we get. If we buy food, we have to pay for it. If a doctor treats us, we know there will be a bill to pay. These are private bills. But there are also public bills to be paid. They are paid by the government. In turn we get the needed services. We pay for these services through taxes.What would happen if everyone stopped paying taxes? The water supply would stop; the streets might not be cleaned; schools would be closed. We would not want to live in such a city. The chief duty of every government is to protect persons and property. More than three-fourths of government expenses are used for this purpose. The next largest amount of public money goes to teach and train our citizens. Billions of dollars each year are spent on schools and libraries. Also, a large amount of public funds is spent on roads.Most of the needed funds is raised by taxes. The law orders us to pay taxes. We have no choice in the matter.Years ago the government made money by selling public lands. But most of the best public lands have now been sold. There are still some public lands that contain oil, coal and other natural resources. They could be sold, but we want to save them for future years. So, we all must pay our share for the services that make our lives comfortable.19. What does the speaker mainly talk about?20. What is most of the government money used for?21. How did the government raise money to pay public bills in the past?Questions 22 to 25 are based on the passage you have just heard.Did you know that, besides larger places like France and Germany, Europe is home to several extremely tiny countries? One of these countries contains less than a square mile of land. Another is surrounded on all sides by Italy. Yet each is an independent land, with its own government, trade, and customs.One of the best known of these small countries is Monaco. It is situated on the Mediterranean Sea and surrounded by France on three sides. Monaco became familiar to Americans when its ruler, Prince Rainier, married the American actress Grace Kelly. Rainier's family has ruled Monaco almost continuously since 1297. The land has been independent for over three hundred years.Andorra, with an area of some 200 square miles, is considerably larger than Monaco. This country is located in the Pyrenees Mountains, with France on one side and Spain on the other. Potatoes and tobacco are grown in Andorra's steep mountain valleys. One of the products it exports is clothing. Andorra is also known for its excellent skiing locations.Within the Alps in Central Europe is Liechtenstein, a tiny country of about 30,000 people who speak mostly German. Liechtenstein uses the same money as its neighbor Switzerland, but it has been an independent country since the 1860s. Taxes are low, so many businesses have their headquarters here. The country makes and exports a lot of machinery.Other small, independent states in Europe are San Marino and Luxembourg. Each of these has unique qualities as well.22. What does the speaker say about Monaco?23. Why did Monaco become familiar to Americans according to the speaker?24. What is one of the products Andorra exports?25. What does the speaker mainly talk about?This is the end of listening comprehension.。

A new study（26）that belief, questioning whether brains really can be distinguished by gender.In the study, Tel Aviv University researchers（27）for sex differences the entire human brain.And what did they find Not much. Rather than offer evidence for （28）brains as “male” or “female,” research shows that brains fall into a wide range, with most people falling right in the middle.Daphna Joel, who led the study, said her research found that while there are some gender-based（29）, many different types of brain can’t always be distinguished by gender.While the “average” male and “average” female brains were （30）different, you couldn’t tell it by look ing at individual brain scans. Only a small（31）of people had “all-male” or “all-female” characteristics.Larry Cahill, an American neuroscientist (神经科学家),said the study is an important addition to a growing body of research questioning（32） beliefs about gender and brain function. But he cautioned against concluding from this study that all brains are the same,（33）of gender.“There’s a mountain of evidence（34）the importance of sex influences at all levels of brain function,” he told The Seattle Times.If anything, he said, the study（35） that gender plays a very important role in the brain “even when we are not clear exactly how.”Section BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Can Burglars Jam Your Wireless Security System[A]Any product that promises to protect your home deserves careful examination. So it is n’t surprising that you’ll findplenty of strong opinions about the potential vulnerabilities of popular home-security systems.[B]The most likely type of burglary (入室盗窃) by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted roughly two-thirds of all household burglaries in the US in wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal using technical means to bypass a security system are so small that the FBI doesn’t even track those statistics.[C]One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar (入室盗贼) might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming With the right device tuned to the right frequency, what’sto stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station[D]Jamming concerns are nothing new, and they’re not unique to se curity systems. Any device that’s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, let’s say you wanted to “jam” a conversation between two people—all you’d need to do is yell in the listener’s ear.[E] Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimal Googling. They will, however, need so know what system th ey’re looking for. If you have a sign in your yard declaring what setup you use, that’d point them in the right direction, though at that point, we’re talking about a highly targeted, semi-sophisticated attack, and not the sort forced-entry attack that mak es up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.[F] Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editor’s Choice distinction, utilizes a special system that’scapable of separating incidental RF interference from targeted jamming attacks. When the system thinks it’s being jammed, it’ll notify you via push alert(推送警报).From there, it’s up to you to sound the alarm manually.[G] SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measures to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it’s possible with the right equipment. However, we also verified that SimpliSafe’s anti-jamming system works. It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not in detected them.[H]We like the unique nature of that software. It means that a thief lik ely wouldn’t be able to Google how the system works, then figure out a way around it. Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly from system to system, which means there wouldn’t be a universal mag ic formula for cracking it. Other systems also seem confident on thesubject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t any documented cases of succe ssful jam attack since the company began offering wireless security sensors in the 1980s.[I] Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff [J] Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you’re away. S o the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or opened door would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However, he’llneed to do so without tripping the anti-jamming system, the details of which he almost certainly does now have access to.[K]At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunisticsmash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of aless-extraordinary attack.36. It is possible for burglars to make jamming attacks with thenecessary equipment and skill.37. Interfering with a wireless security system is similar tointerfering with a conversation.38. A burglar has to continuously jam the wireless security deviceto avoid triggering the alarm, both inside and outside the house.39. SimpliSafe provides devices that are able to distinguishincidental radio interference from targeted jamming attacks.40. Only a very small proportion of burglaries are committed by technical means.41. It is difficult to crack SimpliSafe as its system keeps changing.42. Wireless devices will transmit signals so as to activate thealarm once something wrong is detected.43. Different measures should be taken to protect one’s home fromburglary in addition to the wireless security system.44. SimpliSafe’s device can send a warning to the house owner’s cellphone.45. Burglars can easily get a security device’s frequency by Internet search.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.As a person who writes about food and drink for a living. I couldn’t tell you the first thing about Bill Perry or whether the beers he sells are that great. But I can tell you that I like this guy. That’s because he plans to ban tipping in favor of paying his servers an actual living wage.I hate tipping.I hate it because it’s an obligation disguised as an option. I hate it for the post-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have a voice in how much money your server makes. No matter how the math works out, you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true, we would all be slipping a few 100-dollar bills to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers of humanity that they are, are catching on to this; in one poll, a full 30% said they didn’t believe the job they did had any impact on the tips they received.So come on, folks: get on board with ditching the outdated tip system. Pay a little more upfront for your beer or burger. Support Bill Perry’s pub, and any other bar or restaurant that doesn’t ask you to do drunken math.46. What can we learn about Bill Perry from the passageA) He runs a pub that serves excellent beer.B) He intends to get rid of the tipping practice.C) He gives his staff a considerable sum for tips.D) He lives comfortably without getting any tips.47. What is the main reason why the author hates tippingA) It sets a bad example for other industries.B) It adds to the burden of ordinary customers.C) It forces the customer to compensate the waiter.D) It poses a great challenge for customers to do math.48. Why do many people love tipping according to the authorA) They help improve the quality of the restaurants they dine in.B) They believe waiters deserve such rewards for good service.C) They want to preserve a wonderful tradition of the industry.D) They can have some say in how much their servers earn.49. What have some waiters come to realize according to a surveyA) Service quality has little effect on tip size.B) It is in human mature to try to save on tips.C) Tips make it more difficult to please customers.D) Tips benefit the boss rather that the employees.50. What does the author argue for in the passageA) Restaurants should calculate the tips for customers.B) Customers should pay more tips to help improve service.C) Waiters deserve better than just relying on tips for a living.D) Waiters should be paid by employers instead of customers. Passage TwoQuestions 51 to 55 are based on the following passage.In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakenedSome experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more money in their pockets when they’re paying less at the pump. They spend that money on other things, which stimulates the economy.The biggest gains go to countries that import most of their oil like China, Japan, and India, But doesn’t the extra money in the pock ets of those countries’ consumers mean an equal loss in oilproducing countries, cancelling out the gains Not necessarily, says economic researcher Sara Johnson. “Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies(补贴) for their consumers.”But not all oil producers have big reserves, In Venezuela, collapsing oil prices have sent its economy into free-fall. Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly because oil-producing nations can’t afford to import as much as they used to.Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy.Consumers, in the . at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number ofoil-producing countries are trimming their gasoline subsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.51. What does the author mainly discuss in the passageA) The reasons behind the plunge of oil prices.B) Possible ways to stimulate the global economy.C) The impact of cheap oil on global economic growth.D) The effect of falling oil prices on consumer spending.52. Why do some experts believe cheap oil will stimulate the global economyA) Manufacturers can produce consumer goods at a much lower cost.B) Lower oil prices have always given a big boost to the global economy.C) Oil prices may rise or fall but economic laws are not subject to change.D) Consumers will spend their saving from cheap oil on other commodities.53. What happens in many oil-exporting countries when oil prices go downA) They suspend import of necessities from overseas.B) They reduce production drastically to boost oil prices.C) They use their money reserves to back up consumption.D) They try to stop their economy from going into free-fall.54. How does Carl Weinberg view the current oil price plungeA) It is one that has seen no parallel in economic history.B) Its negative effects more than cancel out its positive effects.C) It still has a chance to give rise to a boom in the global economy.D) Its effects on the global economy go against existing economic laws.55. Why haven’t falling oil prices boosted the global economy as they did beforeA) People are not spending all the money they save on gas.B) The global economy is likely to undergo another recession.C) Oil importers account for a larger portion of the global economy.D) People the world over are afraid of a further plunge in oil prices.Part IV Translation (30minutes)Directions: For this part,you are allowed 30minutes to transtate a passage from Chinese into should write your answer on Answer Sheet 2.在中国文化中，红色通常象征着好运、长寿和幸福，在春节和其他喜庆场合，红色到处可见。

As we all known, talking and listening are commonly used in communication, but how can you talk without listening to others? Good conversation skills include much more than simply talking to others, listening is also a necessary quality of a successful person.I firmly believe that listening is of greater significance than talking. For one thing, If you can not listen correctly, you can not talk properly. Just imagine a world where everyone keep talking but nobody listening, it's useless to say anything then. For another, if you want to make achievement in social settings, relationships and business, one way to ensure your success is to be a great listener.Therefore, in order to enhance our conversation skills, here are a few simple rules we can follow to help us become a better listener, such as stopping talking endlessly, giving your full attention to the speaker and making an effort to shift the focus of the conversation to the other person. All in all, nothing can instead of listening! (169 words)2016年12月英语四级作文范文：活到老学到老(1)2016年12月大学英语四级考试如期而至，今年四级作文题目之一是“活到老学到老”。

A new study（26）that belief, questioning whether brains really can be distinguished by gender.In the study, Tel Aviv University researchers（27）for sex differences the entire human brain.And what did they find? Not much. Rather than offer evidence for （28）brains as “male” or “female,” research shows that brains fall into a wide range, with most people falling right in the middle.Daphna Joel, who led the study, said her research found that while there are some gender-based（29）, many different types of brain can’t always be distinguished by gender.While the “average” male and “average” female brains were（30）different, you couldn’t tell it by loo king at individual brain scans. Only a small（31）of people had “all-male” or “all-female” characteristics.Larry Cahill, an American neuroscientist (神经科学家),said the studyis an important addition to a growing body of research questioning（32）beliefs about gender and brain function. But he cautioned against concluding from this study that all brains are the same,（33）of gender.“There’s a mountain of evidence（34）the importance of sex influences at all levels of brain function,” he told The Seattle Times.If anything, he said, the study（35） that gender plays a very important role in the brain “even when we are not clear exactly how.”Section BDirections: In this section, you are going to read a passage with ten statements attached to it.

Answer the questions by marking the corresponding letter on Answer Sheet 2.Can Burglars Jam Your Wireless Security System?[A]Any product that promises to protect your home deserves careful examination. So it i sn’t surprising that you’ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.[B]The most likely type of burglary (入室盗窃) by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted roughly two-thirds of all household burglaries in the US in 2013.The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal usingtechnical means to bypass a security system are so small that the FBI doesn’t even track those statistics.[C]One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar (入室盗贼) might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming? With the right device tuned to the right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?[D]Jamming concerns are nothing new, and they’re not unique to security systems. Any device that’s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, let’s say you wanted to “jam”a conversation between two people—all you’d need to do is yell in the listener’s ear.[E] Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimal Googling. They will, however, need so know what system they’re looking for. If you have a sign in your yard declaring what setup you use, that’d point them in the right direction, though at that point, we’re talking about a highly targeted, se mi-sophisticated attack, and not the sort forced-entry attack that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.[F] Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editor’s Choice distinction, utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks. When the system thinks it’s being jammed, it’ll notify you via push alert(推送警报).From there, it’s up to you to sound the alarm manually.[G] SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measures to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it’s possible with the right equipm ent. However, we also verified that SimpliSafe’s anti-jamming system works. It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not in detected them.[H]We like the unique nature of that software. It means that a thief likely wouldn’t be able to Google how the system works, then figure out a way around it. Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly from system to system, which means there wouldn’t be a universal magic formula for cracking it. Other systems also seem confident on the subject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t any documented cases of successful jam attack since the company began offering wireless security sensors in the 1980s.[I] Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff?[J] Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you’re away. So the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or openeddoor would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s insid e and searching for things to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does now have access to.[K]At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.36. It is possible for burglars to make jamming attacks with the necessaryequipment and skill.37. Interfering with a wireless security system is similar to interferingwith a conversation.38. A burglar has to continuously jam the wireless security device to avoidtriggering the alarm, both inside and outside the house.39. SimpliSafe provides devices that are able to distinguish incidentalradio interference from targeted jamming attacks.40. Only a very small proportion of burglaries are committed by technical means.41. It is difficult to crack SimpliSafe as its system keeps changing.42. Wireless devices will transmit signals so as to activate the alarmonce something wrong is detected.43. Different measures should be taken to protect one’s home fromburglary in addition to the wireless security system.44. Sim pliSafe’s device can send a warning to the house owner’s cellphone.45. Burglars can easily get a security device’s frequency by Internet search.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.As a person who writes about food and drink for a living. I couldn’t tell you the first thing about Bill Perry or whether the beers he sells are that great. But I can tell you that I like this guy. That’s because he plans to ban tipping in favor of paying his servers an actual living wage.I hate tipping.I hate it because it’s an obligation disguised as an option. I hate it for the post-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have avoice in how much money your server makes. No matter how the math works out, you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true, we would all be slipping a few 100-dollar bills to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers of humanity that they are, are catching on to this; in one poll, a full 30% said they didn’t bel ieve the job they did had any impact on the tips they received.So come on, folks: get on board with ditching the outdated tip system. Pay a little more upfront for your beer or burger. Support Bill Perry’s pub, and any other bar or restaurant that doesn’t ask you to do drunken math.46. What can we learn about Bill Perry from the passage?A) He runs a pub that serves excellent beer.B) He intends to get rid of the tipping practice.C) He gives his staff a considerable sum for tips.D) He lives comfortably without getting any tips.47. What is the main reason why the author hates tipping?A) It sets a bad example for other industries.B) It adds to the burden of ordinary customers.C) It forces the customer to compensate the waiter.D) It poses a great challenge for customers to do math.48. Why do many people love tipping according to the author?A) They help improve the quality of the restaurants they dine in.B) They believe waiters deserve such rewards for good service.C) They want to preserve a wonderful tradition of the industry.D) They can have some say in how much their servers earn.49. What have some waiters come to realize according to a survey?A) Service quality has little effect on tip size.B) It is in human mature to try to save on tips.C) Tips make it more difficult to please customers.D) Tips benefit the boss rather that the employees.50. What does the author argue for in the passage?A) Restaurants should calculate the tips for customers.B) Customers should pay more tips to help improve service.C) Waiters deserve better than just relying on tips for a living.D) Waiters should be paid by employers instead of customers.Passage TwoQuestions 51 to 55 are based on the following passage.In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened?Some experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more money in their pockets when they’r e paying less at the pump. They spend that money on other things, which stimulates the economy.The biggest gains go to countries that import most of their oil like China, Japan, and India, But doesn’t the extra money in the pockets of those countries’ co nsumers mean an equal loss in oil producing countries, cancelling out the gains? Not necessarily, says economic researcher Sara Johnson. “Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies(补贴) for their consumers.”But not all oil producers have big reserves, In Venezuela, collapsing oil prices have sent its economy into free-fall.Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly because oil-producing nations can’t afford to import as much as they used to.Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy.Consumers, in the U.S. at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasoline subsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.51. What does the author mainly discuss in the passage?A) The reasons behind the plunge of oil prices.B) Possible ways to stimulate the global economy.C) The impact of cheap oil on global economic growth.D) The effect of falling oil prices on consumer spending.52. Why do some experts believe cheap oil will stimulate the global economy?A) Manufacturers can produce consumer goods at a much lower cost.B) Lower oil prices have always given a big boost to the global economy.C) Oil prices may rise or fall but economic laws are not subject to change.D) Consumers will spend their saving from cheap oil on other commodities.53. What happens in many oil-exporting countries when oil prices go down?A) They suspend import of necessities from overseas.B) They reduce production drastically to boost oil prices.C) They use their money reserves to back up consumption.D) They try to stop their economy from going into free-fall.54. How does Carl Weinberg view the current oil price plunge?A) It is one that has seen no parallel in economic history.B) Its negative effects more than cancel out its positive effects.C) It still has a chance to give rise to a boom in the global economy.D) Its effects on the global economy go against existing economic laws.55. Why haven’t falling oil prices boosted the global economy as they did before?A) People are not spending all the money they save on gas.B) The global economy is likely to undergo another recession.C) Oil importers account for a larger portion of the global economy.D) People the world over are afraid of a further plunge in oil prices.Part IV Translation (30minutes)Directions: For this part,you are allowed 30minutes to transtate a passage from Chinese into English.You should write your answer on Answer Sheet 2.在中国文化中，红色通常象征着好运、长寿和幸福，在春节和其他喜庆场合，红色到处可见。

Animal experiments by psychologists at the University of Pennsylvania had shown that after repeated failures, most animals conclude that a situation is hopeless and beyond their control. After such an experience an animal often remains passive even when it can effect change-a state they called learned helplessness.[B]People can learn to be helpless, too. Why do some students give up when encounter difficulty, whereas others who are no more skilled continue to strive and learn? One answer, I soon discovered, lay in people’s beliefs about why they had failed.[C] In particular, attributing poor performance to a lack of ability depresses motivation more than does the belief that lack of effort is to blame. When I told a group of school children who displayed helpless behavior that a lack of effort led to their mistakes in math, they learned to keep trying when the problems got tough. Another group of helpless children who were simply rewarded for their success on easier problems did not improve their ability to solve harm math problems. These experiments indicated that a focus on effort can help resolve helplessness and generate success.[D]Later, I developed a broader theory of what separates the two general classes of learners-helpless versus mastery-oriented. I realized these different types of students not only explain their failures differently, but they also hold differe nt “theories”of intelligence. The helpless ones believe intelligence is a fixed characteristic: you have only a certain amount, and that's that. I call this a "fixed mind-set(思维模式)."Mistakes crack their self-confidence because they attribute errors to a lack of ability, which they feel powerless to change. They avoid challenges because challenges make mistakes more likely. The mastery-orient children, on the other hand, think intelligence is not fixed and can be developed through education and hard work. Such children believe challenges are energizing rather than intimidating (令人生畏);they offer opportunities to learn. Students with such a growth mind-set were destined(注定)for great academic success and were quite likely to outperform their counterparts.[E]We validated these expectations in a study in which two other psychologists and I monitored 373 student for two years during the transition to junior high school, when the work gets more difficult and the grading more strict, to determine how their mind-sets might affect their math grades. At the beginning of seventh grade, we assessed the students' mind-sets by asking them to agree or disagree with statements such as "Your intelligence is something very basic about you that you can't really change." We then assessed their beliefsabout other aspects of learning and looked to see what happened to their grades.[F] As predicted, the students with a growth mind-set felt that learning was more important goal than getting good grades. In addition, they held hard work in high regard, They understood that even geniuses have to work hard. Confronted by a setback such as a disappointing test grade, students with a growth mind-set said they would study harder or try a different strategy. The students who held a fixed mind-set, however, were concerned about looking smart with less regard for learning. They had negative views of effort, believing that having to work hard was a sign of low ability. They thought that a person with talent or intelligence did not need to work hard to do well. Attributing a bad grade to their own lack of ability, those with a fixed mind-set said that would study less in the future, try never to take that subject again and consider cheating on future tests.[G] Such different outlook had a dramatic impact on performance. At the start of junior high, the math achievement test scores of the students with a growth mind-set were comparable to the those of students who displayed a fixed mind-set. But as the work became more difficult, the students with a growth mind-set showed greater persistence. As a result, their math grades overtook those of the other students by the end of the first semester-and the gap between the two groups continued to widen during the two years we followed them.[H] A fixed mind-set can also hinder communication and progress in the workplace and discourage or ignore constructive criticism and advice. Research shows that managers who have a fixed mind-set are less likely to seek or welcome feedback from their employees than are managers with a growth mind-set.[I] How do we transmit a growth mind-set to our children? One way is by telling stories about achievements that result from hard work. For instance, talking about mathematical geniuses Who were more or less born that way puts students in a fixed mind-set, but mathematicians who fell in love with math and developed amazing skills produce a growth mind-set.[J] In addition, parents and teachers can help children by providing explicit instruction regarding the mind as a learning machine, I designed an eight-session workshop for 91 students whose math grades were declining in their first year of junior high. Forty-eight of the students received instruction in study skills only, whereas the others attended a combination of study skills sessions and classes in which they learned about the growth mind-set and how to apply it to schoolwork. In the growth mind-set classes, students read and discussed an article entitled “You Can Grow Your Brain.” They were taught that the brain is like a muscle that gets stronger with use and that learning prompts the brain to grow new connections. From such instruction, many students began to see themselves as agents of their own brain development.

For each of them there are four choices maked A），B），C）and D）.You should decide on the best choice and mark the corresponding letter on Answer Sheet2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage."Sugar, alcohol and tobacco," economist Adam Smith once wrote, "are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, and which are, therefore, extremely popular subjects of taxation."Two and a half centuries on, most countries impose some sort of tax on alcohol and tobacco. With surging obesity levels putting increasing strain on public health systems, governments around the world have begun to toy with the idea of taxing sugar as well.Whether such taxes work is a matter of debate. A preliminary review of Mexico's taxation found a fall in purchases of taxed drinks as well as a rise in sales if untaxed and healthier drinks. By contrast, a Danish tax on foods high in fats was abandoned a year after its introduction, amid claims that consumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattier fare.The food industry has, in general, been firmly opposed to such direct government action. Nonetheless, the renewed focus on waistlines means that industry groups are under pressure to demonstrate their products are healthy as well as tasty.Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufactures have cut the amount of sugar in their beverages.Many of the reductions over the past 30 years have been achieved either by reducing the amount of sugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however.Some companies have been investing money in a more ambitious undertaking: learning how to adjust the fundamental make-up of the food they sell. For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.While reformulating recipes(配方)is one way to improve public health, it should be part of a multi-sided approach. The key is to remember thatthere is not just one solution. To deal with obesity, a mixture of approaches-including reformulation, taxation and adjusting portion sizes-will be needed. There is no silver bullet.46. What did Adam Smith say about sugar, alcohol and tobacco?A)They were profitable to manufacture.B)They were in ever-increasing demand.C)They were subject to taxation almost everywhere.D)They were no longer considered necessities of life.47.Why have many countries started to consider taxing sugar?A)They are under growing pressures to balance their national budgets.B)They find it ever harder to cope with sugar-induced health problems.C)They practice of taxing alcohol and tobacco has proved both popular and profitable.D)The sugar industry is overtaking alcohol and tobacco business in generating profits.48.What do we learn about Danish taxation on fat-rich foods?A)It did not work out as well as was expected.B)It gave rise to a lot of problems on the border.C)It could not succeed without German cooperation.D)It met with firm opposition from the food industry.49.What is the more recent effort by food companies to make foods and drinks both healthy and tasty?A)Replacing sugar or salt with alternative ingredients.B)Setting a limit on the amount of sugar or salt in their products.C)Investing in research to find ways to adapt to consumers' needs.D)Adjusting the physical composition of their products.50.What does the author mean by saying, at the end of the passage, "There is no silver bullet"(Line 4, Para 7)?A)There is no single easy quick solution to the problem.B)There is no hope of success without public cooperation.C)There is on hurry in finding ways to solve the obesity problem.D)There is no effective way to reduce people's sugar consumption.Passage TwoQuestions 51 to 55 are based on the following passage.You may have heard some of the fashion industry horror stories: models eating tissues or cotton balls to hold off hunger, and models collapsing from hunger-induced heart attacks just seconds after they step off the runway.Excessively skinny models have been a point of controversy for decades, and two researchers say a model's body mass should be a workspace health and safety issue. In an editorial released Monday in the American Journal of Public Health, Katherine Record and Bryn Austin made their case for government regulation of the fashion industry.The average international runway model has a body mass index (BMI) under 16-low enough to indicate starvation by the World Health Organization's standard. And Record and Austin are worried not just about the models themselves, but about the vast number of girls and women their images influence."Especially girls and tens", says Record. "Seventy percent of girls aged 10 to 18 report that they define perfect body image based on what they see in magazines." That's especiallyworrying, she says, given that anorexia(厌食症)results in more deaths than does any other mental illness, according to the National Institute of Mental Health.It's commonly known that certain diseases are linked with occupations like lung disease in coal miners. Professional fashion models are particularly vulnerable to eating disorders resulting from occupational demands to maintain extreme thinness.Record's suggestion is to prohibit agents from hiring models with a BMI below 18.In April, France passed a law setting lower limits for a model's weight. Agents and fashion houses who hire models with BMI under 18 could pay $82,000 in fines and spend up to 6 months in jail. Regulating the fashion industry in the United States won't be easy, Record says. But with the new rules in France, U.S. support could make a difference. "A designer can't survive without participating in Paris Fashion Week", she says, adding, "Our argument is that the same would be true of New York Fashion Week."51.What do Record and Austin say about fashion models' body mass?A)It has caused needless controversy.B)It is focus of the modeling business.C)It is but a matter of personal taste.D)It affects models' health and safety.52.What are Record and Austin advocating in the Monday editorial?A)A change in the public's view of female beauty.B)Government legislation about models' weight.C)Elimination of forced weight loss by models.D)Prohibition of models eating non-food stuff.53.Why are Record and Austin worried about the low body mass index of models?A)It contributes to many mental illnesses.B)It defines the future of the fashion industry.C)It has great influence on numerous girls and women.D)It keeps many otherwise qualified women off the runaway.54. What do we learn about France's fashion industry?A)It has difficulty hiring models.B)It has now a new law to follow.C)It allows girls under 18 on the runway.D)It has overtaken that of the United States.55. What does Record expect of New York Fashion Week?A)It will create a completely new set of rules.B)It will do better than Paris Fashion Week.C)It will differ from Paris Fashion Week.D)It will have models with a higher BMI.Part IV Translation （30 minutes）Directions：For this part，you are allowed 30minutes to translate a passage from Chinese into English .You should write your answer on Answer Sheet 2.在中国文化中，黄颜色是一种很重要的颜色，因为它具有独特的象征意义。

You are to make a choice between the two. Write an essay to explain the reasons for your choice.You should write at least 120 words but no more than 180 words.参考范文：Upon graduation, virtually all college students will confront the problem of the career choice，which is truly a tough choice. Students' opinions differ greatly on this issue. Some hold that priority should be given to take a job, but others take the attitude that going to a graduate school is the most critical factor influencing their future careerchoices.As to myself, I prefer the latter view. A higher educational backgroundexerts a tremendous fascination on a great number of people, with noexception to me. This phenomenon t hat the graduates have difficulties in finding job after their graduation can easily be found anywhere in ourdaily life, especially on campus. On t he one hand, with the improved high education of Chinese college students whichdirectly brought the resultthat there are more and more graduates every year. On the contrary, jobvacancies don’t increase that fast. More people, less food, which is the exact description of the hard condition. On the other hand, more and more people go on to pursue their master and doctor degree; more and moreChinese oversea students come b ack to China to hunt better working chances. It is sure that the competition is more and more fierce.Therefore, it is high time that we took effective measures to improve our own competitiveness. That is the secret of success in the futureemployment market after our graduation.Part Ⅲ Reading Section A(卷二)The ocean is heating up.

Eachstatement contains information given in one of the paragraphs. Identify the paragraphfrom which the information is derived. You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking thecorresponding letter on Answer Sheet 2.The Secret to Raising Smart KidsA) I first began to investigate the basis of human motivation--and how people persevere aftersetbacks--as a psychology graduate student at Yale University in the 1960s. Animal experiments bypsychologists at the University of Pennsylvania had shown that after repeated failures, most animalsconclude that a situation is hopeless and beyond their control. After such an experience an animaloften remains passive even when it can effect change--a state they called learned helplessness.B) People can learn to be helpless, too. Why do some students give up when they encounter difficulty,whereas others who are no more skilled continue to strive and learn? One answer, I soondiscovered, lay in people's beliefs about why they had failed.C) In particular, attributing poor performance to a lack of ability depresses motivation more than doesthe belief that lack of effort is to blame. When I told a group of school children who displayedhelpless behavior that a lack of effort led to their mistakes in math, they learned to keep tryingwhen the problems got tough. Another group of helpless children who were simply rewarded fortheir success on easier problems did not improve their ability to solve hard math problems. Theseexperiments indicated that a focus on effort can help resolve helplessness and generate success.D) Later, I developed a broader theory of what separates the two general classes of learners--helplessversus mastery-oriented. I realized these different types of students not only explain their failuresdifferently, but they also hold different "theories" of intelligence.The helpless ones believeintelligence is a fixed characteristic: you have only a certain amount, and that's that. I call this a"fixed mind-set (思维模式). " Mistakes crack their self-confidence because they attribute errors toa lack of ability, which they feel powerless to change. They avoid challenges because challengesmake mistakes more likely. The mastery-oriented children, on the other hand, think intelligence isnot fixed and can be developed through education and hard work. Such children believe challengesare energizing rather than intimidating (令人生畏); they offer opportunities to learn. Studentswith such a growth mind-set were destined (注定) for greater academic success and were quitelikely to outperform their counterparts.E) We validated these expectations in a study in which two other psychologists andI monitored 373students for two years during the transition to junior high school, when the work gets more difficultand the grading more strict, to determine how their mind-sets might affect their math grades. At thebeginning of seventh grade, we assessed the students' mind-sets by asking them to agree or disagreewith statements such as "Your intelligence is something very basic about you that you can't reallychange. " We then assessed their beliefs about other aspects of learning and looked to see whathappened to their grades.F) As predicted, the students with a growth mind-set felt that learning was a more important goal thangetting good grades. In addition, they held hard work in high regard. They understood that evengeniuses have to work hard. Confronted by a setback such as a disappointing test grade, studentswith a growth mind-set said they would study harder or try a different strategy. The students whoheld a fixed mind-set, however, were concerned about looking smart with less regard for learning.They had negative views of effort, believing that having to work hard was a sign of low ability.They thought that a person with talent or intelligence did not need to work hard to do well.Attributing a bad grade to their own lack of ability, those with a fixed mind-set said that they wouldstudy less in the future, try never to take that subject again and consider cheating on future tests.G) Such different outlooks had a dramatic impact on performance. At the start of junior high, the mathachievement test scores of the students with a growth mind-set were comparable to those ofstudents who displayed a fixed mind-set. But as the work became more difficult, the students witha growth mind-set showed greater persistence. As a result, their math grades overtook those of theother students by the end of the first semester--and the gap between the two groups continued towiden during the two years we followed them.H) A fixed mind-set can also hinder communication and progress in the workplace and discourage orignore constructive criticism and advice. Research shows that managers who have a fixed mind-setare less likely to seek or welcome feedback from their employees than are managers with a growthmind-set.I) How do we transmit a growth mind-set to our children? One way is by telling stories aboutachievements that result from hard work. For instance, talking about mathematical geniuses whowere more or less born that way puts students in a fixed mind-set, but descriptions of greatmathematicians who fell in love with math and developed amazing skills produce a growth mind-set.J) In addition, parents and teachers can help children by providing explicit instruction regarding themind as a learning machine. I designed an eight-session workshop for 91 students whose mathgrades were declining in their first year of junior high.Forty-eight of the students receivedinstruction in study skills only, whereas the others attended a combination of study skills sessionsand classes in which they learned about the growth mind-set and how to apply it to schoolwork. Inthe growth mind-set classes, students read and discussed an article entitled "You Can Grow YourBrain. " They were taught that the brain is like a muscle that gets stronger with use and thatlearning prompts the brain to grow new connections. From such instruction, many students beganto see themselves as agents of their own braindevelopment. Despite being unaware that there weretwo types of instruction, teachers reported significant motivational changes in 27% of the childrenin the growth mind-set workshop as compared with only 9% of students in the control group. K) Research is converging (汇聚) on the conclusion that great accomplishment and even genius istypically the result of years of passion and dedication and not something that flows naturally from agift.36. The author's experiment shows that students with a fixed mind-set believe having to work hard is an indication of low ability.37. Focusing on effort is effective in helping children overcome frustration and achieve success.38. We can cultivate a growth mind-set in children by telling success stories that emphasize hard work and love of learning.39. Students' belief about the cause of their failure explains their attitude toward setbacks.40. In the author's experiment, students with a growth mind-set showed greater perseverance in solving difficult math problems.41. The author conducted an experiment to find out about the influence of students' mind-sets on math learning.42. After failing again and again, most animals give up hope.43. Informing students about the brain as a learning machine is a good strategy to enhance their motivation for learning.44. People with a fixed mind-set believe that one's intelligence is unchangeable.45. In the workplace, feedback may not be so welcome to managers with a fixed mind-set.Section CDirections: There are 2 passages in this section.

A new study（26）that belief, questioning whether brains really can be distinguished by gender.In the study, Tel Aviv University researchers（27）for sex differences the entire human brain.And what did they find? Not much. Rather than offer evidence for（28）brains as “male” or “female,” research shows that brains fall into a wide range, with most people falling right in the middle.Daphna Joel, who led the study, said her research found that while there are some gender-based（29）, many different types of brain can’t always be distinguished by gender.While the “average” male and “average” female brains were（30）different, you couldn’t tell it by loo king at individual brain scans. Only a small （31）of people had “all-male” or “all-female” characteristics.Larry Cahill, an American neuroscientist (神经科学家),said the study is an important addition to a growing body of research questioning（32）beliefs about gender and brain function. But he cautioned against concluding from this study that all brains are the same,（33）of gender.“There’s a mountain of evidence（34）the importance of sex influences at all levels of brain function,” he told The Seattle Times.If anything, he said, the study（35）that gender plays a very important role in the brain “even when we are not clear exactly how.”Section BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Can Burglars Jam Your Wireless Security System?[A]Any product that promises to protect your home deserves careful examination. So it isn’t surprising that you’ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.[B]The most likely type of burglary (入室盗窃) by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted roughly two-thirds of all household burglaries in the US in 2013.The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal using technical means to bypass a security system are so small that the FBI doesn’t even track those statistics.[C]One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar (入室盗贼) might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming? With the right device tuned to the right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?[D]Jamming concerns are nothing new, and they’re not unique to security systems. Any device that’s built to receive a wireless signal at aspecific frequency can be overwhelmed by a stronger signal coming in on the same f requency. For comparison, let’s say you wanted to “jam” a conversation between two people—all you’d need to do is yell in the listener’s ear.[E] Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimal Googling. They will, however, need so know what system they’re looking for. If you have a sign in your yard declaring what setup you use, that’d point them in the right direction, though at that point, we’re talki ng about a highly targeted, semi-sophisticated attack, and not the sort forced-entry attack that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.[F] Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editor’s Choice distinction, utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks. When the syste m thinks it’s being jammed, it’ll notify you via push alert(推送警报).From there, it’s up to you to sound the alarm manually.[G] SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measures to contain the RF interference to our test lab, we tested the attack out forourselves, and were able to verify that it’s possible with the right equipment. However, we also verifie d that SimpliSafe’s anti-jamming system works. It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not in detected them.[H]We like the unique nature of that software. It means that a thief likely wouldn’t be able to Google how the system works, then figure out a way around it. Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly from system to system, which means there wouldn’t be a universal magic formula for cracking it. Other systems also seem confident on the subject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t any documented cases of successful jam attack since the company began offering wireless security sensors in the 1980s.[I] Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff?[J] Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going toneed to target your home, specifically. Then, he’s going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you’re away. So the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or opened door would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However, he’ll need to do so without tripping theanti-jamming system, the details of which he almost certainly does now have access to.[K]At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.36. It is possible for burglars to make jamming attacks with the necessaryequipment and skill.37. Interfering with a wireless security system is similar to interfering with aconversation.38. A burglar has to continuously jam the wireless security device to avoidtriggering the alarm, both inside and outside the house.39. SimpliSafe provides devices that are able to distinguish incidental radiointerference from targeted jamming attacks.40. Only a very small proportion of burglaries are committed by technical means.41. It is difficult to crack SimpliSafe as its system keeps changing.42. Wireless devices will transmit signals so as to activate the alarm oncesomething wrong is detected.43. Different measur es should be taken to protect one’s home from burglaryin addition to the wireless security system.44. SimpliSafe’s device can send a warning to the house owner’s cellphone.45. Burglars can easily get a security device’s frequency by Internet search. Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.As a person who writes about food and drink for a living. I couldn’t tell you the first thing about Bill Perry or whether the beers he sells are that great. But I can tell you that I like this guy. That’s because he plans to ban tipping in favor of paying his servers an actual living wage.I hate tipping.I hate it because it’s an obligation disguised as an option. I hate it for the post-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have a voice in how much money your server makes. No matter how the math works out,you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true, we would all be slipping a few 100-dollar bills to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers of humanity that they are, are catching on to this; in one poll, a full 30% said they didn’t believe the job they did had any impact on the tips they received.So come on, folks: get on board with ditching the outdated tip system. Pay a little more upfront for your beer or burger. Support Bill Perry’s pub, and any other bar or restaurant that doesn’t ask you to do drunken math.46. What can we learn about Bill Perry from the passage?A) He runs a pub that serves excellent beer.B) He intends to get rid of the tipping practice.C) He gives his staff a considerable sum for tips.D) He lives comfortably without getting any tips.47. What is the main reason why the author hates tipping?A) It sets a bad example for other industries.B) It adds to the burden of ordinary customers.C) It forces the customer to compensate the waiter.D) It poses a great challenge for customers to do math.48. Why do many people love tipping according to the author?A) They help improve the quality of the restaurants they dine in.B) They believe waiters deserve such rewards for good service.C) They want to preserve a wonderful tradition of the industry.D) They can have some say in how much their servers earn.49. What have some waiters come to realize according to a survey?A) Service quality has little effect on tip size.B) It is in human mature to try to save on tips.C) Tips make it more difficult to please customers.D) Tips benefit the boss rather that the employees.50. What does the author argue for in the passage?A) Restaurants should calculate the tips for customers.B) Customers should pay more tips to help improve service.C) Waiters deserve better than just relying on tips for a living.D) Waiters should be paid by employers instead of customers. Passage TwoQuestions 51 to 55 are based on the following passage.In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened?Some experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more money in their pockets when they’re paying less at the pump. They spend that money on other things, which stimulates the economy.The biggest gains go to countries that import most of their oil like China, Japan, and India, But doesn’t the extra money in the pockets of those countries’ consumers mean an equal loss in oil producing countries, cancelling out the gains? Not necessarily, says economic researcher Sara Johnson. “Many oil producers built u p huge reserve funds when prices werehigh, so when prices fall they will draw on their reserves to support government spending and subsidies(补贴) for their consumers.”But not all oil producers have big reserves, In Venezuela, collapsing oil prices have sent its economy into free-fall.Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly becauseoil-pro ducing nations can’t afford to import as much as they used to.Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy.Consumers, in the U.S. at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasoline subsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.51. What does the author mainly discuss in the passage?A) The reasons behind the plunge of oil prices.B) Possible ways to stimulate the global economy.C) The impact of cheap oil on global economic growth.D) The effect of falling oil prices on consumer spending.52. Why do some experts believe cheap oil will stimulate the global economy?A) Manufacturers can produce consumer goods at a much lower cost.B) Lower oil prices have always given a big boost to the global economy.C) Oil prices may rise or fall but economic laws are not subject to change.D) Consumers will spend their saving from cheap oil on other commodities.53. What happens in many oil-exporting countries when oil prices go down?A) They suspend import of necessities from overseas.B) They reduce production drastically to boost oil prices.C) They use their money reserves to back up consumption.D) They try to stop their economy from going into free-fall.54. How does Carl Weinberg view the current oil price plunge?A) It is one that has seen no parallel in economic history.B) Its negative effects more than cancel out its positive effects.C) It still has a chance to give rise to a boom in the global economy.D) Its effects on the global economy go against existing economic laws.55. Why haven’t falling oil prices boosted the global economy as they did before?A) People are not spending all the money they save on gas.B) The global economy is likely to undergo another recession.C) Oil importers account for a larger portion of the global economy.D) People the world over are afraid of a further plunge in oil prices.Part IV Translation (30minutes)Directions: For this part,you are allowed 30minutes to transtate a passage from Chinese into English.You should write your answer on Answer Sheet 2.在中国文化中，红色通常象征着好运、长寿和幸福，在春节和其他喜庆场合，红色到处可见。

Red can be found everywhere during Chinese Spring Festival and other joyous occasions. Cashes often in red envelopes are sent to family members or close friends as gifts. Its popularity can also be attributed the fact that people accociate it with Chinese revolution and Communist Party. However, it does not always equal to good luck and joy in that the name of the dead used to be written in red. Using red ink to write names of Chinese people were seen as an offense.卷二卷三：白色参考范文：With China’s reform and opening up, many young people tend to hold Western-style weddings these days. The bride wears a white wedding dress at the wedding, because white is considered as a symbol of purity. However, in traditional Chinese culture, white is often used in funerals, so be sure to remember that white flowers must not be used as a gift to the patient, especially not to the seniors or critically illed patients. Similarly, the cash gift cannot be packed in a white envelope, but in a red envelope.作文参考答案第一套：Directions: For this part, you are allowed 30 minutes to write an essay. Suppose you have two options upon graduation. One is to find a job somewhere and the other to start a business of your own. You are to make a decision. Write an essay to explain the reasons for your decision. You should write at least 120 words but no more than 180 words.精彩范文：In the past two years of my college life, I have never ceased to think what kind of work I shall take up upon graduation. Although my ideas are not consistent, I have now decided to start a business of my own as my lifelong career.A variety of factors have led me to make this decision over other more lucrative ones. To begin with, running my own business means freedom and independence. As a person having my own business, I am free to use my own ideas and make my own decisions, a privilege not everyone can have, even those with highly-paid positions. More importantly, I like starting my own business in that it offers a certain peace of mind. No more rushing to catch a morning bus, no more anxiety to please a boss, no more worries about your paycheck which is steady, if not handsome.Nothing, not even a big salary, can equal for the satisfaction of being your own boss and a gentle peace of life.第二套：外教一对一Directions: For this part, you are allowed 30 minutes to write an essay. Suppose you have two options upon graduation. One is to work in a state-owned business and the other in a joint venture. You are to make a choice between the two. Write an essay to explain the reasons for your choice. You should write at least 120 words but no more than 180 words.参考范文：Upon graduation, virtually all college students will confront the problem of the career choice，which is truly a tough choice. Students' opinions differ greatly on this issue. Some hold that priority should be given to start a business of your own, but others take the attitude that finding a job is the best choice influencing their future.As to myself, I prefer the latter view. An opportunity to start a business exerts a tremendous fascination on a great number of people, with no exception to me. In my view, With the competition in the job market becoming increasingly fierce for college graduates， some ambitious students have tried their hands at launching their own businesses. Over the years，there have been many successful cases of student entrepreneurship and such attempts should be encouraged and promoted by both the universities and the society at large. What’s more ,College students who start businesses are pioneers，among whom will be born China’s future business leaders. Faced with unknown challenge s， they are audacious enough to embark on a perilous journey while most of their peers enjoy stable salaries by working as white-collars at high-end office buildings.All in all, the essential difference between the students who find a job or those students who create their own businesses is that the former are docile followers whereas the latter are aggressive trailblazers. For this reason， business-launching college graduates are more admirable， and thus they command our deep respect.第三套：Directions: For this part, you are allowed 30 minutes to write an essay.Suppose you have two options upon graduation.

A higher educational background exerts a tremendous fascination on a great number of people, with no exception to me. This phenomenon that the graduates have difficulties in finding job after their graduation can easily be found anywhere in our daily life, especially on campus. On the one hand, with the improved high education of Chinese college students which directly brought the result that there are more and more graduates every year. On the contrary, job vacancies don’t increase that fast. More people, less food, which is the exact deion of the hard condition. On the other hand, more and more people go on to pursue their master and doctor degree; more and more Chinese oversea students come back to China to hunt better working chances. It is sure that the competition is more and more fierce.外教一对一Therefore, it is high time that we took effective measures to improve our own competitiveness. That is the secret of success in the future employment market after our graduation.。

Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer sheet 2.The Secret to Raising Smart Kids[A] I first began to investigate the basis of human motivation-and how people persevere after setbacks-as a psychology graduate student at Yale University in the 1960s. Animal experiments by psychologists at the University of Pennsylvania had shown that after repeated failures, most animals conclude that a situation is hopeless and beyond their control. After such an experience an animal often remains passive even when it can effect change-a state they called learned helplessness.[B]People can learn to be helpless, too. Why do some students give up when encounter difficulty, whereas others who are no more skilled continue to strive and learn One answer, I soon discovered, lay in people’s beliefs about why they had failed.[C] In particular, attributing poor performance to a lack of ability depresses motivation more than does the belief that lack of effort is to blame. When I told a group of school children who displayed helpless behavior that a lack of effort led to their mistakes in math, they learned to keep trying when the problems got tough. Another group of helpless children who were simply rewarded for their success on easier problems did not improve their ability to solve harm math problems. These experiments indicated that a focus on effort can help resolve helplessness and generate success.[D]Later, I developed a broader theory of what separates the two general classes of learners-helpless versus mastery-oriented. I realized these different types of students not only explain their failures differently, but they also hold different “theories”of intelligence. The helpless ones believe intelligence is a fixed characteristic: you have only a certain amount, and that's that. I call this a "fixed mind-set(思维模式)."Mistakes crack their self-confidence because they attribute errors to a lack of ability, which they feel powerless to change. They avoid challenges because challenges make mistakes more likely. The mastery-orient children, on the other hand, think intelligence is not fixed and can be developed through education and hard work. Such children believe challenges are energizing rather than intimidating (令人生畏);they offer opportunities to learn. Students with such a growth mind-set were destined(注定)for great academic success and were quite likely to outperform their counterparts.[E]We validated these expectations in a study in which two other psychologists and I monitored 373 student for two years during the transition to junior high school, when the work gets more difficult and the grading more strict, to determine how their mind-sets might affect their math grades. At the beginning of seventh grade, we assessed the students' mind-sets by asking them to agree or disagree with statements such as "Your intelligence is something very basic about you that you can't really change." We then assessed their beliefs about other aspects of learning and looked to see what happened to their grades.[F] As predicted, the students with a growth mind-set felt that learning was more important goal than getting good grades. In addition, they held hard work in high regard, They understood that even geniuses have to work hard. Confronted by a setback such as adisappointing test grade, students with a growth mind-set said they would study harder or try a different strategy. The students who held a fixed mind-set, however, were concerned about looking smart with less regard for learning. They had negative views of effort, believing that having to work hard was a sign of low ability. They thought that a person with talent or intelligence did not need to work hard to do well. Attributing a bad grade to their own lack of ability, those with a fixed mind-set said that would study less in the future, try never to take that subject again and consider cheating on future tests.[G] Such different outlook had a dramatic impact on performance. At the start of junior high, the math achievement test scores of the students with a growth mind-set were comparable to the those of students who displayed a fixed mind-set. But as the work became more difficult, the students with a growth mind-set showed greater persistence. As a result, their math grades overtook those of the other students by the end of the first semester-and the gap between the two groups continued to widen during the two years we followed them.[H] A fixed mind-set can also hinder communication and progress in the workplace and discourage or ignore constructive criticism and advice. Research shows that managers who have a fixed mind-set are less likely to seek or welcome feedback from their employees than are managers with a growth mind-set.[I] How do we transmit a growth mind-set to our children One way is by telling stories about achievements that result from hard work. For instance, talking about mathematical geniuses Who were more or less born that way puts students in a fixed mind-set, but mathematicians who fell in love with math and developed amazing skills produce a growth mind-set.[J] In addition, parents and teachers can help children by providing explicit instruction regarding the mind as a learning machine, I designed an eight-session workshop for 91 students whose math grades were declining in their first year of junior high. Forty-eight of the students received instruction in study skills only, whereas the others attended a combination of study skills sessions and classes in which they learned about the growth mind-set and how to apply it to schoolwork. In the growth mind-set classes, students read and discussed an article entitled “You Can Grow Your Brain.” They were taught that the brain is lik e a muscle that gets stronger with use and that learning prompts the brain to grow new connections. From such instruction, many students began to see themselves as agents of their own brain development. Despite being unaware that there were two types of instruction, teachers reported significant motivational changes in 27% of the children in the growth mind-set workshop as compared with only 9% of students in the control group.[K]Research is converging(汇聚)on the conclusion that great accomplishment and even genius is typically the result of years of passion and dedication and not something that flows naturally from a gift.36.The author's experiment shows that students with a fixed mind-set believe having to work hard is an indication of low ability.37.Focusing on effort is effective in helping children overcome frustration and achieve success.38.We can cultivate a growth mind-set in children by telling success stories that emphasize hard work love of learning.39.Students’ belief about the cause of th eir failure explains their attitude toward setbacks.40.In the author’s experiment, student with a growth mind-set showed greater perseverance insolving difficult math problems.41.The author conducted an experiment to find out about the influence of stud ents’ mind-sets on math learning.42.After failing again and again, most animals give up hope.rming students about the brain as a learning machine is a good strategy to enhance their motivation for learning.44.People with a fixed mind-set believe that one’s intelligence is unchangeable.45.In the workplace, feedback may not be so welcome to managers with a fixed mind-set. Section CDirections：There are 2 passages in this section .Each passage is followed by some questions or unfinished statements. For each of them there are four choices maked A），B），C）and D）.You should decide on the best choice and mark the corresponding letter on Answer Sheet2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage."Sugar, alcohol and tobacco," economist Adam Smith once wrote, "are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, and which are, therefore, extremely popular subjects of taxation."Two and a half centuries on, most countries impose some sort of tax on alcohol and tobacco. With surging obesity levels putting increasing strain on public health systems, governments around the world have begun to toy with the idea of taxing sugar as well.Whether such taxes work is a matter of debate. A preliminary review of Mexico's taxation found a fall in purchases of taxed drinks as well as a rise in sales if untaxed and healthier drinks. By contrast, a Danish tax on foods high in fats was abandoned a year after its introduction, amid claims that consumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattier fare.The food industry has, in general, been firmly opposed to such direct government action. Nonetheless, the renewed focus on waistlines means that industry groups are under pressure to demonstrate their products are healthy as well as tasty.Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufactures have cut the amount of sugar in their beverages.Many of the reductions over the past 30 years have been achieved either by reducing the amount of sugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however.Some companies have been investing money in a more ambitious undertaking: learning how to adjust the fundamental make-up of the food they sell. For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.While reformulating recipes(配方)is one way to improve public health, it should be part of a multi-sided approach. The key is to remember thatthere is not just one solution. To deal with obesity, a mixture of approaches-including reformulation, taxation and adjusting portion sizes-will be needed. There is no silver bullet.46. What did Adam Smith say about sugar, alcohol and tobaccoA)They were profitable to manufacture.B)They were in ever-increasing demand.C)They were subject to taxation almost everywhere.D)They were no longer considered necessities of life.47.Why have many countries started to consider taxing sugarA)They are under growing pressures to balance their national budgets.B)They find it ever harder to cope with sugar-induced health problems.C)They practice of taxing alcohol and tobacco has proved both popular and profitable.D)The sugar industry is overtaking alcohol and tobacco business in generating profits.48.What do we learn about Danish taxation on fat-rich foodsA)It did not work out as well as was expected.B)It gave rise to a lot of problems on the border.C)It could not succeed without German cooperation.D)It met with firm opposition from the food industry.49.What is the more recent effort by food companies to make foods and drinks both healthy and tastyA)Replacing sugar or salt with alternative ingredients.B)Setting a limit on the amount of sugar or salt in their products.C)Investing in research to find ways to adapt to consumers' needs.D)Adjusting the physical composition of their products.50.What does the author mean by saying, at the end of the passage, "There is no silver bullet"(Line 4, Para 7)A)There is no single easy quick solution to the problem.B)There is no hope of success without public cooperation.C)There is on hurry in finding ways to solve the obesity problem.D)There is no effective way to reduce people's sugar consumption.Passage TwoQuestions 51 to 55 are based on the following passage.You may have heard some of the fashion industry horror stories: models eating tissues or cotton balls to hold off hunger, and models collapsing from hunger-induced heart attacks just seconds after they step off the runway.Excessively skinny models have been a point of controversy for decades, and two researchers say a model's body mass should be a workspace health and safety issue. In an editorial released Monday in the American Journal of Public Health, Katherine Record and Bryn Austin made their case for government regulation of the fashion industry.The average international runway model has a body mass index (BMI) under 16-low enough to indicate starvation by the World Health Organization's standard. And Record and Austin are worried not just about the models themselves, but about the vast number of girls and women their images influence."Especially girls and tens", says Record. "Seventy percent of girls aged 10 to 18 report that they define perfect body image based on what they see in magazines." That's especially worrying, she says, given that anorexia(厌食症)results in more deaths than does any other mental illness, according to the National Institute of Mental Health.It's commonly known that certain diseases are linked with occupations like lung disease in coal miners. Professional fashion models are particularly vulnerable to eating disordersresulting from occupational demands to maintain extreme thinness.Record's suggestion is to prohibit agents from hiring models with a BMI below 18.In April, France passed a law setting lower limits for a model's weight. Agents and fashion houses who hire models with BMI under 18 could pay $82,000 in fines and spend up to 6 months in jail. Regulating the fashion industry in the United States won't be easy, Record says. But with the new rules in France, U.S. support could make a difference. "A designer can't survive without participating in Paris Fashion Week", she says, adding, "Our argument is that the same would be true of New York Fashion Week."51.What do Record and Austin say about fashion models' body massA)It has caused needless controversy.B)It is focus of the modeling business.C)It is but a matter of personal taste.D)It affects models' health and safety.52.What are Record and Austin advocating in the Monday editorialA)A change in the public's view of female beauty.B)Government legislation about models' weight.C)Elimination of forced weight loss by models.D)Prohibition of models eating non-food stuff.53.Why are Record and Austin worried about the low body mass index of modelsA)It contributes to many mental illnesses.B)It defines the future of the fashion industry.C)It has great influence on numerous girls and women.D)It keeps many otherwise qualified women off the runaway.54. What do we learn about France's fashion industryA)It has difficulty hiring models.B)It has now a new law to follow.C)It allows girls under 18 on the runway.D)It has overtaken that of the United States.55. What does Record expect of New York Fashion WeekA)It will create a completely new set of rules.B)It will do better than Paris Fashion Week.C)It will differ from Paris Fashion Week.D)It will have models with a higher BMI.Part IV Translation （30 minutes）Directions：For this part，you are allowed 30minutes to translate a passage from Chinese into English .You should write your answer on Answer Sheet 2.在中国文化中，黄颜色是一种很重要的颜色，因为它具有独特的象征意义。

We then assessed their beliefs about other aspects of learning and looked to see what happened to their grades.[F] As predicted, the students with a growth mind-set felt that learning was more important goal than getting good grades. In addition, they held hard work in high regard, They understood that even geniuses have to work hard. Confronted by a setback such as a disappointing test grade, students with a growth mind-set said they would study harder or try a different strategy. The students who held a fixed mind-set, however, were concerned about looking smart with less regard for learning. They had negative views of effort, believing that having to work hard was a sign of low ability. They thought that a person with talent or intelligence did not need to work hard to do well. Attributing a bad grade to their own lack of ability, those with a fixed mind-set said that would study less in the future, try never to take that subject again and consider cheating on future tests.[G] Such different outlook had a dramatic impact on performance. At the start of junior high, the math achievement test scores of the students with a growth mind-set were comparable to the those of students who displayed a fixed mind-set. But as the work became more difficult, the students with a growth mind-set showed greater persistence. As a result, their math grades overtook those of the other students by the end of the first semester-and the gap between the two groups continued to widen during the two years we followed them.[H] A fixed mind-set can also hinder communication and progress in the workplace and discourage or ignore constructive criticism and advice. Research shows that managers who have a fixed mind-set are less likely to seek or welcome feedback from their employees than are managers with a growth mind-set.[I] How do we transmit a growth mind-set to our children? One way is by telling stories about achievements that result from hard work. For instance, talking about mathematical geniusesWho were more or less born that way puts students in a fixed mind-set, but mathematicians who fell in love with math and developed amazing skills produce a growth mind-set.[J] In addition, parents and teachers can help children by providing explicit instruction regarding the mind as a learning machine, I designed an eight-session workshop for 91 students whose math grades were declining in their first year of junior high. Forty-eight of the students received instruction in study skills only, whereas the others attended a combination of study skills sessions and classes in which they learned about the growth mind-set and how to apply it to schoolwork. In the growth mind-set classes, students read and discussed an article entitled “You Can Grow Your Brain.” They were taught that the brain is like a muscle that gets stronger with use and that learning prompts thebrain to grow new connections. From such instruction, many students began to see themselves as agents of their own brain development. Despite being unaware that there were two types of instruction, teachers reported significant motivational changes in 27% of the children in the growth mind-set workshop as compared with only 9% of students in the control group.[K]Research is converging(汇聚)on the conclusion that great accomplishment and even genius is typically the result of years of passion and dedication and not something that flows naturally from a gift.36.The author's experiment shows that students with a fixed mind-set believe having to work hard is an indication of low ability.37.Focusing on effort is effective in helping children overcome frustration and achieve success.38.We can cultivate a growth mind-set in children by telling success stories that emphasize hard work love of learning.39.Students’ belief about the cause of their failure explains their attitud e toward setbacks.40.In the author’s experiment, student with a growth mind-set showed greater perseverance in solving difficult math problems.41.The author conducted an experiment to find out about the influence of students’ mind-sets on math learning.42.After failing again and again, most animals give up hope.rming students about the brain as a learning machine is a good strategy to enhance their motivation for learning.44.People with a fixed mind-set believe that one’s intelligence is unchang eable.45.In the workplace, feedback may not be so welcome to managers with a fixed mind-set.Section CDirections：There are 2 passages in this section .Each passage is followed by some questions or unfinished statements. For each of them there are four choices maked A），B），C）and D）.You should decide on the best choice and mark the corresponding letter on Answer Sheet2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage."Sugar, alcohol and tobacco," economist Adam Smith once wrote, "are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, and which are, therefore, extremely popular subjects of taxation."Two and a half centuries on, most countries impose some sort of tax on alcohol and tobacco. With surging obesity levels putting increasing strain on public health systems, governments around the world have begun to toy with the idea of taxing sugar as well.Whether such taxes work is a matter of debate. A preliminary review of Mexico's taxation found a fall in purchases of taxed drinks as well as a rise in sales if untaxed and healthier drinks. By contrast, a Danish tax on foods high in fats was abandoned a year after its introduction, amid claims that consumers were avoiding it by crossing theborder to Germany to satisfy their desire for cheaper, fattier fare.The food industry has, in general, been firmly opposed to such direct government action. Nonetheless, the renewed focus on waistlines means that industry groups are under pressure to demonstrate their products are healthy as well as tasty.Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufactures have cut the amount of sugar in their beverages.Many of the reductions over the past 30 years have been achieved either by reducing the amount of sugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however.Some companies have been investing money in a more ambitious undertaking: learning how to adjust the fundamental make-up of the food they sell. For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.While reformulating recipes(配方)is one way to improve public health, it should be part of a multi-sided approach. The key is to remember thatthere is not just one solution. To deal with obesity, a mixture of approaches-including reformulation, taxation and adjusting portion sizes-will be needed. There is no silver bullet.46. What did Adam Smith say about sugar, alcohol and tobacco?A)They were profitable to manufacture.B)They were in ever-increasing demand.C)They were subject to taxation almost everywhere.D)They were no longer considered necessities of life.47.Why have many countries started to consider taxing sugar?A)They are under growing pressures to balance their national budgets.B)They find it ever harder to cope with sugar-induced health problems.C)They practice of taxing alcohol and tobacco has proved both popular and profitable.D)The sugar industry is overtaking alcohol and tobacco business in generating profits.48.What do we learn about Danish taxation on fat-rich foods?A)It did not work out as well as was expected.B)It gave rise to a lot of problems on the border.C)It could not succeed without German cooperation.D)It met with firm opposition from the food industry.49.What is the more recent effort by food companies to make foods and drinks both healthy and tasty?A)Replacing sugar or salt with alternative ingredients.B)Setting a limit on the amount of sugar or salt in their products.C)Investing in research to find ways to adapt to consumers' needs.D)Adjusting the physical composition of their products.50.What does the author mean by saying, at the end of the passage, "There is no silver bullet"(Line 4, Para 7)?A)There is no single easy quick solution to the problem.B)There is no hope of success without public cooperation.C)There is on hurry in finding ways to solve the obesity problem.D)There is no effective way to reduce people's sugar consumption.Passage TwoQuestions 51 to 55 are based on the following passage.You may have heard some of the fashion industry horror stories: models eating tissues or cotton balls to hold off hunger, and models collapsing from hunger-induced heart attacks just seconds after they step off the runway.Excessively skinny models have been a point of controversy for decades, and two researchers say a model's body mass should be a workspace health and safety issue. In an editorial released Monday in the American Journal of Public Health, Katherine Record and Bryn Austin made their case for government regulation of the fashion industry.The average international runway model has a body mass index (BMI) under 16-low enough to indicate starvation by the World Health Organization's standard. And Record and Austin are worried not just about the models themselves, but about the vast number of girls and women their images influence."Especially girls and tens", says Record. "Seventy percent of girls aged 10 to 18 report that they define perfect body image based on what they see in magazines." That's especially worrying, she says, given that anorexia(厌食症)results in more deaths than does any other mental illness, according to the National Institute of Mental Health.It's commonly known that certain diseases are linked with occupations like lung disease in coal miners. Professional fashion models are particularly vulnerable to eating disorders resulting from occupational demands to maintain extreme thinness.Record's suggestion is to prohibit agents from hiring models with a BMI below 18.In April, France passed a law setting lower limits for a model's weight. Agents and fashion houses who hire models with BMI under 18 could pay $82,000 in fines and spend up to 6 months in jail. Regulating the fashion industry in the United States won't be easy, Record says. But with the new rules in France, U.S. support could make a difference. "A designer can't survive without participating in Paris Fashion Week", she says, adding, "Our argument is that the same would be true of New York Fashion Week."51.What do Record and Austin say about fashion models' body mass?A)It has caused needless controversy.B)It is focus of the modeling business.C)It is but a matter of personal taste.D)It affects models' health and safety.52.What are Record and Austin advocating in the Monday editorial?A)A change in the public's view of female beauty.B)Government legislation about models' weight.C)Elimination of forced weight loss by models.D)Prohibition of models eating non-food stuff.53.Why are Record and Austin worried about the low body mass index of models?A)It contributes to many mental illnesses.B)It defines the future of the fashion industry.C)It has great influence on numerous girls and women.D)It keeps many otherwise qualified women off the runaway.54. What do we learn about France's fashion industry?A)It has difficulty hiring models.B)It has now a new law to follow.C)It allows girls under 18 on the runway.D)It has overtaken that of the United States.55. What does Record expect of New York Fashion Week?A)It will create a completely new set of rules.B)It will do better than Paris Fashion Week.C)It will differ from Paris Fashion Week.D)It will have models with a higher BMI.Part IV Translation （30 minutes）Directions：For this part，you are allowed 30minutes to translate a passage from Chinese into English .You should write your answer on Answer Sheet 2.在中国文化中，黄颜色是一种很重要的颜色，因为它具有独特的象征意义。
