You may not use any of the words in the bankmore than once.As if you needed another reason to hate the gym, it now turns out that exercise can exhaust not only your muscles, but also your eyes. Fear not, however, for coffee can stimulate them again. During26 exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a 27 called "central fatigue," in which an imbalance in the body's chemical messengers prevents the central nervous system from directing muscle movements 28 . It was not known , however , whether central fatigue might also affect motor systems not directly 29 in the exercise itself, such as those that move the eyes. To find out, researchers gave 11 volunteer cyclists a carbohydrate (碳水化合物的）30 either with a moderate dose of caffeine (咖啡因），which is known to stimulate the central nervous system ,or as a placebo (安慰剂）without, during 3 hours of 31 . After exercising ,the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still 32 their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%, 33 their ability to capture new visual information. The caffeine, the equivalent of two strong cups of coffee, was 34 to reverse this effect, with some cyclists even displaying 35 eye movement speeds. So it might be a good idea to get someone else to drive you home after that marathon.A)cautiously B)commit C)controlD)cycling E)effectively F)increasedG)involved H)limited I)phenomenonJ)preventing K)sensitive L)slowingM)solution N)sufficient O)vigorousSection Ba passage wit ten statements attac e to it. Each statement contains Directions: In讥is section ,you are going to read·h h d·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 questionsby marking the corresponding letter on Answer Sheet 2.Team SpiritA)Teams have become the basic building blocks of organisations. Recruitment advertisements routinely call for"team players. " Business schools grade their students in part on their performance in group projects. Office managers knock down walls to encourage team building. Teams are as old as civilisation, of course: even Jesus had 12 co-workers. But a new report by Deloitte, "Global Human Capital Trends," based on a survey of more than 7,000 executives in over 130 countries, suggests that the fashion for teamwork has reached a new high.Almost half of those surveyed said their companies were either in the middle of restructuring or about to embark on (开始）it; and for the most part, restructuring meant putting more emphasis on teams.B)Companies are abandoning conventional functional departments and organising employees into cross-disciplinaryteams that focus on particular products, problems or customers. These teams are gaining more power to run their own affairs. They are also spending more time working with each other rather than reporting upwards. Deloitte argues that a new organisational form is on the rise: a network of teams is replacing the conventional hierarchy （等级体制）．C)The fashion for teams is driven by a sense that the old way of organising people is too rigid for both the modemmarketplace and the expectations of employees. Technological innovation places greater value on agility (灵活性）. John Chambers, chairman of Cisco Systems Inc. ,a worldwide leader in electronics products, says that "we compete against market transitions (过渡），not competitors. Product transitions used to take five or seven years; now they take one or two. "Digital technology also makes it easier for people to co-ordinate their activities without resorting to hierarchy. The "millennials" (千禧一代）who will soon make up half the workforce in rich countries were raised from nursery school onwards to work in groups.D)The fashion for teams is also spreading from the usual corporate suspects (such as GE and IBM) to some moreunusual ones. The Cleveland Clinic, a hospital operator, has reorganised its medical staff into teams to focus on particular treatment areas; consultants, nurses and others collaborate closely instead of being separated by speciality (专业）and rank. The US Army has gone the same way. In his book, Team of Teams ,General Stanley McChrystal describes how the army's hierarchicalstructure hindered its operations during the early stages of the Iraq war. His solution was to learn something from the rebels it was fighting: decentralising authority to self-organising teams.E)A good rule of thumb is that as soon as generals and hospital administrators jump on a management bandwagon（追随一种管理潮流），it is time to ask questions. Leigh Thompson of Kellogg School of Management in Illinois warns that, "Teams are not always the answer—teams may provide insight, creativity and knowledge ina way that a person working independently cannot; but teamwork may also lead to confusion, delay and poordecision-making." The late Richard Hackman of Harvard University once argued, "I have no question that when you have a team, the possibility exists that it will generate magic, producing something extraordinary. ..But don't count on it. "F)Hackman (who died in 2013) noted that teams are hindered by problems of co-ordination and motivation thatchip away at the benefits of collaboration. High-flyers (能干的人）who are forced to work in teams may be undervalued and free-riders empowered. Group-think may be unavoidable. In a study of旦Q teams of senior executives, he discovered that less than 10% of their supposed members agreed on who exactly was on the team.If it is hard enough to define a team's membership, agreeing on its purpose is harder still.G)Profound changes in the workforce are making teams trickier to manage. Teams work best if their members havea strong common culture. This is hard to achieve when, as is now the case in many big firms, a large proportionof staff are temporary contractors. Teamwork improves with time: America's National Transportation Safety Board found that 73% of the incidents in its civil-aviation database occurred on a crew's first day of flying together. However, as Amy Edmondson of Harvard points out, organisations increasingly use "team" as a verb rather than a noun: they form teams for specific purposes and then quickly disband them.H)The least that can be concluded from this research is that companies need to think harder about managing teams.They need to rid their minds of sentimentalism (感情用事）：the most successful teams have leaders who are able to set an overall direction and take immediate action. They need to keep teams small and focused: giving in to pressure to be more "inclusive" is a guarantee of dysfunction. Jeff Bezos, Amazon's boss, says that "If I see more than two pizzas for lunch, the team is too big. "They need to immunise teams against group-think: Hackman argued that the best ones contain "deviants" (离经叛道者）who are willing to do something that maybe upsetting to others.I) A new study of 12,000 workers in 17 countries by Steelcase, a furniture-maker which also does consulting, findsthat the best way to ensure employees are "engaged" is to give them more control over where and how they do their work—which may mean liberating them from having to do everything in collaboration with others.J)However, organisations need to learn something bigger than how to manage teams better: they need to be in the habit of asking themselves whether teams are the best tools for the job. Team-building skills are in short supply: Deloitte reports that only 12% of the executives they contacted feel they understand the way people work together in networks and only 21 %feel confident in their ability to build cross-functional teams. Loosely managed teams can become hotbeds of distraction—employees routinely complain that they can't get their work done because they are forced to spend too much time in meetings or compelled to work in noisy offices. Even in the age of open­plan offices and social networks some work is best left to the individual.36.Successful team leaders know exactly where the team should go and are able to take prompt action.37.Decentralisation of authority was also found to be more effective in military operations.38.In many companies, the conventional form of organisation is giving way to a network of teams.39.Members of poorly managed teams are easily distracted from their work.40.Teamwork is most effective when team members share the same culture.41.According to a report by Deloitte, teamwork is becoming increasingly popular among companies.42.Some team members find it hard to agree on questions like membership and the team's purpose.43.Some scholars think teamwork may not always be reliable, despite its potential to work wonders.44.To ensure employees'commitment, it is advisable to give them more flexibility as to where and how they work.45.Product transitions take much less time now than in the past.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 andmark 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.Shoppers in the UK are spending less money on toilet paper to save money ,research has shown.Penny-pinching UK consumers choose cheaper products from discounters such as Aldi and Lidl rather than luxury alternatives.This has wiped 6% off the value of the soft tissue paper market in the UK. It has shrunk from£1. 19 billion in 2011 to£1. 12 billion in 2015, according to a new report from market research company Mintel. Furthermore, the future of the market looks far from rosy ,with sales expected to fall further to£1. 11 billion in 2016.In the last year alone ,despite an increase in the UK population and a subsequent rise in the number of households, sales of toilet paper fell by 2 % , with the average household reducing their toilet roll spending from£43 in 2014 to£41 in 2015.Overall, almost three in five people say they try to limit the让usage of paper—including facial tissue and kitchen roll—to save money. "Strength, softness and thickness remain the leading indicators of toilet paper quality, with just a small proportion of consumers preferring more luxurious alternatives, such as those with flower patterns or perfume, "said Mintel analyst Jack Duckett. " T hese extra features are deemed unnecessary by the majority of shoppers ,which probably reflects how these types of products are typically more expensive than regular toilet paper,even when on special offer."While consumers are spending less on toilet paper, they remain fussy—in theory at least—when it comes to paper quality. Top of Britons'toliet paper wish list is softness (57%) followed by strength (45%) and thickness (36%).One in 10 buyers rank toliet rolls made from recycled paper among their top considerations, highlighting how overall the environment is much less of a consideration for shoppers than product quality. In a challenge for manufacturers ,81 %of paper product users said they would consider buying recycled toilet tissue if it were comparable in quality to standard paper.46. The market sales of toilet paper have decreased because.A)Britons have cut their spending on itB)its prices have gone up over the yearsC)its quality has seen marked improvementD)Britons have developed the habit of saving4 7. What does the author think of the future of the tissue paper market in the UK?A)It will expand in time.B)It will remam gloomy.C)It will experience ups and downs.D)It will recover as population grows.48. What does Jack Duckett say about toilet paper?A)Special offers would promote its sales.B)Consumers are loyal to certain brands.C)Luxurious features add much to the price.D)Consumers have a variety to choose from.49. What do we learn about Britons concerning toilet paper?A)They are particular about the quality of toilet paper.B)They emphasize the strength of toilet paper the most.C)They prefer cheap toilet paper to recycled toilet paper.D)They reject using toilet paper with unnecessary features.50. What can we infer from the last paragraph?A)More and more Britons buy recycled toilet paper to protect the environment.B)Toilet paper manufacturers are facing a great challenge in promoting its sales.C)Toilet paper manufacturers compete with one another to improve product quality.D)Environmental protection is not much of a concern when Britons buy toilet paper.Passage TwoQuestions 51 to 55 are based on the following passage."One of the reasons I find this topic very interesting is because my mom was a smoker when I was younger, " says Lindson-Hawley, who studies tobacco and health at the University of Oxford.By studying about 700 adult smokers ,she found out that her mom quit the right way—by stopping abruptly and completely.In her study, participants were randomly (随机地）assigned to two groups. One had to quit abruptly on a given day, going from about a pack a day to zero. The other cut down gradually over the course of two weeks. People in both groups used nicotine (尼古丁）patches before they quit ,in addition to a second form of nicotine replacement , like gum or spray. They also had talk therapy with a nurse before and after quit day.Six months out, more people who had quit abruptly had stuck with it—more than one-fifth of them, comparedto about one-seventh in the other group. Although these numbers appear low, it is much higher than if people try without support.And the quit rates were particularly convincing given that before the study started, most of the people had said they'd rather cut down gradually before quitting. "If you're training for a marathon, you wouldn't expect to turn up and just be able to run it. And I think people see that for smoking as well. They think,'Well, if I gradually reduce, it's like practice,"'says Lindson-Hawley. But that wasn't the case. Instead of giving people practice, the gradual reduction likely gave them cravi ngs (瘾）and withdrawal symptoms before they even reached quit day, which could be why fewer people in that group actually made it to that point. "Regardless of your stated preference, if you're ready to quit, quitting abruptly is more effective," says Dr. Gabriela Ferre让a." W hen you can quote a specific number like a fifth of the patients were able to quit, that's compelling. It gives them the encouragement, I think, to really go for it," Ferreira says.People rarely manage to quit the first time they try. But at least, she says, they can maximize the odds of success.51. What does Lindson-Hawley say about her mother?A)She quit smoking with her daughter's help.B)She succeeded in quitting smoking abruptly.C)She was also a researcher of tobacco and health.D)She studied the smoking patterns of adult smokers.52. What kind of support did smokers receive to quit smoking in Lindson-Hawley's study?A)They were given physical training.B)They were looked after by physicians.C)They were encouraged by psychologists.D)They were offered nicotine replacements.53.How does Dr. Gabriela Ferreira view the result of Lindson-Hawley's experiment?A)It is idealized.B)It is unexpected.C)It is encouraging.D)It is misleading.54.The idea of "a marathon" (Line 2, Para. 5) illustrates the popular belief that quitting smoking.A)is something few can accomplish B)needs some practice firstC)requires a lot of patience D)is a challenge at the beginning55. What happens when people try to quit smoking gradually?A)They find it even more difficult.B)They are simply unable to make it.C)They show fewer withdrawal symptoms.D)They feel much less pain in the process.Part IV Translation (30 minutes) Directions : 的r this part, you are allowed 30 minutes to translate a passage f rom Chinese into English.

At the speed of only 30 miles per hour it is the same as falling from a third-floor windows. Wearing a seat belt saves lives; it reduces your chance of death or serious injury by more than half.Therefore drivers or front seat passengers over 14 in most vehicles must wear a seat belt. If you do not, you could be fined up to ￡50. it will not be up to the drivers to make sure you wear your belt. But it will be the driver’s responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.However, you do not have to wear a seat belt if you reversing your vehicle; or you are making a local delivery or collection using a special vehicle; or if you have a valid medical certificate which excuses you from wearing it. Make sure these circumstances apply to you before you decide not to wear you seat belt. Remember you may be taken to court for not doing so, and you may be fined if you cannot prove to the court that you have been excused from wearing it.21.

This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise—and as a result, we are ageing unnecessarily soon.Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of ageing could be slowed down.With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations.Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties.)Contraction of front and side parts—as cells die off—was observed I some subjects in their thirties, but it was still not evident in some sixty- and seventy-year-olds.Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age—using the head.The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant.Matsuzawa’s findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain good blood circulation is through using the brain,” he says, “Think hard and engage in conversation. Don’t rely on pocket calculators.”26. The team of doctors wanted to find out ________.A) why certain people age sooner than othersB) how to make people live longerC) the size of certain people’s brainsD) which people are most intelligent27. On what are their research findings based?A) A survey of farmers in northern Japan.B) Tests performed on a thousand old people.C) The study of brain volumes of different peopleD) The latest development of computer technology.28. The doctor’s test show that ________.A) our brains shrink as we grow olderB) the front section of the brain does not shrinkC) sixty-year-olds have the better brains than thirty-year-oldsD) some people’s brains have contracted more than other people’s29.

According to the passage, which people seem to age slower than the others?A) Lawyers.B) Farmers.C) Clerks.D) Shop assistants.Passage ThreeQuestions 31 to 35 are based on the following passage.On June 17, 1744, the officials from Maryland and Virginia held a talk with the Indians of the Six Nations. The Indians were invited to send boys to William and Mary College. In a letter the next day the refused the offer as follows:We know that you have a high opinion of the kind of learning taught in your colleges, and that the costs of living of our young men, while with you, would be very expensive to you. We are convinced that you mean to do us good by your proposal; and we thank you heartily. But you must know that different nations have different ways of looking at things, and you will therefore not be offended if your ideas of this kind of education happen not t be the same as yours. We have had some experience of it. Several of our young people were formerly brought up at the colleges of the northern provinces: they were taught all your sciences; but, when they came back to us, they were bad runners, ignorant of every means of living in the woods…they were totally good for nothing.We are, however, not the less obliged by your kind offer, though we refuse to accept it; and, to show our grateful sense of it, if the gentlemen of Virginia will send up a dozenof their sons, we will take care of their education, teach them in all we know, and make men of them.31.

Already today, less than forty years later, as computers arerelieving us of more and more of the routine tasks in business and in our personal lives, we are faced with a less dramatic but also less foreseen problem. People tend to be over-trusting of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons may be pushed, or that a computer may simply malfunction (失误).Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong.Questioning and routine double-checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer should come with the warning: for all the help this computer may provide, it should not be seen as a substitute for fundamental thinking and reasoning skills.36. What is the main purpose of this passage?A) To look back to the early days of computers.B) To explain what technical problems may occur with computers.C) To discourage unnecessary investment in computers.D) To warn against a mentally lazy attitude towards computers.37. According to the passage, the initial concern about computers was that they might________.A) change our personal livesB) take control of the worldC) create unforeseen problemsD) affect our businesses38. The passage recommends those dealing with computers to ________.A) be reasonably doubtful about themB) check all their answersC) substitute them for basic thinkingD) use them for business purposes only39. The passage suggests that the present-day problem with regard to computers is________.A) challengingB) psychologicalC) dramaticD) fundamental40. It can be inferred from the passage that the author would disapprove of ________.A) investment in computersB) the use of on e’s internal computerC) double-check on computersD) complete dependence on computers for decision-makingPart III Vocabulary and Structure (20 minutes)Directions: There are 30 incomplete sentences in this part.

Despite having as brain no bigger than the 28 of your index finger, pigeons have a very impressive 29 memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often 30 with spreading disease rather than 31 it, but this long-tailed画mal is highly 32 —. Inside a rat's nose are up to 1 ,000 different types of olfactoryreceptors (嗅觉感受器），whereas humans only have 100 to 200 types. This gives rats the ability to detect 33 smells. As a result, some rats are being put to work to detect TB (肺结核）. When the rats detect the smell, they stop and rub their legs to 34 a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to 35 , but for a rat it takes less than 20 minutes. This rat detection method doesn't rely on specialist equipment. It is also more accurate—the rats are able to find more TB infections and, therefore, save more lives.Section B A)associatedD)nuisanceG)prohibitingJ)speci fyM)tipB)examineE)peakH)sensitiveK)superiorN)treatedC)indicateF)preventingI)slightL)suspiciousO)visualDirections: In this section, you are going to read a passage with ten statements attached to it.

So it may seem rather strange that I have returned to college to finish thedegree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.B)Since there is no way for me to avoid exams ,I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. Tosay I had lost the thread is putting it mildly.C)As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I didsome of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S.presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. "That way they socialize over history outside the class, which wouldn't happen without the pressure of an in-class exam," he explained. "Furthermore, in-class exams force students to learn how to perform under pressure , an essential work skill. "D)He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard werecaught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled "Introduction To Congress. "Some colleges have what they call an "honor code," though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn't just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me go m g.E)Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appealto her school's professors to refrain from take-home exams. "Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries," she told me. "Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention. "F)Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-basedone, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help.Vocational-type classes, such as computer science or journalism, on the other hand, are often more research­oriented and lend themselves to take-home testing. Chris Koch, who teaches "History of Broadcast Journalism"at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. "In my field, it's not what you know—it's what you know how to find out, "says Koch. "There is way too much information, and more coming all the time, for anyone to remember.I want my students to search out the answers to questions by using all the resources available to them. "G)Students'test-form preferences vary, too, often depending on the subject and course difficulty. "I prefer take­home essays because it is then really about the writing, so you have time to edit and do more research, "says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, "I find the in-class ones are more stressful in the short term, but there is immediate relief as you swallow information like mad, and then you get to forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment when the time is up. "Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. "If you understand the material and have the ability to articulate (说出）your thoughts, they should be a breeze. "H)How students ultimately handle tests may depend on their personal test-taking abilities. There are people whoalways wait until the last minute, and make it much harder than it needs to be. And then there are those who, not knowing what questions are coming at them , and having no resources to refer to , can freeze. And then there are we rare folks who fit both those descriptions.I)Yes , my advanced age must factor into the equation (等式），in part because of my inability to access the information as quickly. As another returning student at Columbia, Kate Marber, told me, "We are learning not only all this information, but essentially how to learn again. Our fellow students have just come out of high school. A lot has changed since we were last in school. "J)If nothing else, the situation has given my college son and me something to share. When I asked his opinion on this matter, he responded, "I like in-class exams because the time is already reserved, as opposed to using my free time at home to work on a test, " he responded. It seems to me that a compromise would be receiving the exam questions a day or two in advance, and then doing the actual test in class with the ticking clock overhead. K)Better yet, how about what one Hunter College professor reportedly did recently for her final exam: She encouraged the class not to stress or even study, promising that, "It is going to be a piece of cake. " When the students came in, sharpened pencils in hand, there was not a blue book in sight. Rather, they saw a large chocolate cake and they each were given a slice.36.Elderly students find it hard to keep up with the rapid changes in education.37.Some believe take-home exams may affect students'performance in other courses.38.Certain professors believe in-class exams are ultimately more helpful to students.39.In-class exams are believed to discourage cheating in exams.40.The author was happy to learn she could do some exams at home.41.Students who put off their work until the last moment often find the exams more difficult than they actually are.42.Different students may prefer different types of exams.43.Most professors agree whether to give an in-class or a take-home exam depends on the type of course beingtaught.44.The author dropped out of college some forty years ago.45.Some students think take-home exams will eat up their free time.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 andmark 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.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the "fast-night" effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these画mals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者）. This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar envirorunent of the university's Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found ,as expected ,the participants slept less well on their first night than they did on their second ,taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants'brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球）of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding envirorunent, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularlytimed beeps (峰鸣声）of the same tone and irregular beeps of a different tone during the night. She worked out that , if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46. W hat did researchers find puzzling about the first-night effect?A) To what extent it can trouble people.B) What role it has played in evolution.C) What circumstances may trigger it.D) In what way it can be beneficial.47. W hat do we learn about Dr. Yuka Sasaki doing her research?A)She found birds and dolphins remain alert while asleep.B)She found birds and dolphins sleep in much the same way.C)She got some idea from previous studies on birds and dolphins.D)She conducted studies on birds'and dolphins'sleeping patterns.48. W hat did Dr. Sasaki do when she first did her experiment?A)She monitored the brain activity of participants sleeping in a new envirorunent.B)She recruited 35 participants from her Department of Psychological Sciences.C)She studied the differences between the two sides of participants'brains.D)She tested her findings about birds and dolphins on human subjects.49. W hat did Dr. Sasaki do when re-running her experiment?A)She analyzed the negative effect of irregular tones on brains.B)She recorded participants'adaptation to changed environment.C)She exposed her participants to two different stimuli.D)She compared the responses of different participants.50. W hat did Dr. Sasaki find about the participants in her experiment?A)They tended to enjoy certain tones more than others.B) They tended to perceive irregular beeps as a threat.C) They felt sleepy when exposed to regular beeps.D)They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 55 are based on the following passage.It's time to reevaluate how women handle conflict at work. Being overworked or over-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men to feel exhausted? Nearly twice as many women than men ages 18-44 reported feeling "very tired" or "exhausted", according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying "no." Women want to be able to do it all—volunteer for school parties or cook delicious meals— and so their answer to any request is often "Yes, I can. "Women struggle to say " n o" in the workplace for similar reasons ,including the desire to be liked by their colleagues. Unfortunately, this inability to say "no" may be hurting women's health as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want to be viewed as aggressive or disruptive at work. For example,there's a problem that needs to be addressed immediately, resulting in a dispute over who should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem—even if that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have to be able to delegate and manage resources wisely—including staff expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.51.What does the author say is the problem with women?A)They are often unclear about the career goals to reach.B) They are usually more committed at home than on the job.C) They tend to be over-optimistic about how far they could go.D) They tend to push themselves beyond the limits of their ability.52. Why do working women of child-bearing age tend to feel drained of energy?A)They struggle to satisfy the demands of both work and home.B)They are too devoted to work and unable to relax as a result.C) They do their best to cooperate with their workmates.D)They are obliged to take up too many responsibilities.53.What may hinder the future prospects of career women?A)Their unwillingness to say "no".B)Their desire to be considered powerful.C) An underestimate of their own ability.D)A lack of courage to face challenges.54. Men and women differ in their approach to resolving workplace conflicts in that.A) women tend to be easily satisfiedB) men are generally more persuasiveC) men tend to put their personal interests firstD) Women are much more ready to compromise55.What is important to a good leader?A) A dominant personality.

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.A rat or pigeon might not be the obvious choice to tend to someone who is sick, but these creatures have some 26 skills that could help the treatment of human diseases.Pigeons are often seen as dirty birds and an urban 27 , but they are just the latest in a long line of animals that have been found to have abilities to help humans. Despite having a brain no bigger than the 28 of your index finger, pigeons have a very impressive 29__ memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often 30 with spreading disease rather than 31 it, but this long-tailed animal is highly 32 . Inside a rat's nose are up to 1,000 different types of olfactory receptors (嗅觉感受器), whereas humans only have 100 to 200 types. This gives rats the ability to detect __33 smells. As a result, some rats are being put to work to detect TB(肺结核). When the rats detect the smell, they stop and rub their legs to 34 a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to 35 , but for a rat it takes less than 20 minutes. This rat detection methoddoesn't rely on specialist equipment. It is also more accurate — the rats are able to find more TB infections and, therefore, save more lives.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.Do In-Class Exams Make Students Study Harder?Research suggests they may study more broadly for the unexpected rather than search for answers.[A] I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago.I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.[B] Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly.[C] As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I did some of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. “That way they socialize over history outside the class, whichwouldn’t happen without the pressure of an in-class exam,” he explained, “Furthermore, in-class exams force students to learn how to perform under pressure, and essential work skill.”[D] He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled “Introduction To Congress.”Some colleges have what they call an “honor code,” though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn’t just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me going.[E] Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school’s professors to refrain from take-hone exams. “Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries,” she told me. “Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention.”[F] Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-based one, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help. Vocational-type classes, such as computer science or journalism, on the other hand, are often more research-oriented and lend themselves to take-home testing. Chris Koch, who teaches “History of Broadcast Journalism” at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. “In my field, it’s not what you know—it’s what you know how to find out,” says Koch. “There is way too much information, and more coming all the time, for anyone to remember. I want my students to search out the answers to questions by using all the resources available to them.[G] Students’ test-form preferences vary, too, often depending on the subject and course difficulty. “I prefer take-home essays because it is then really about the writing, so you have time to edit and do more research,” says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, “I find the in-class ones are more stressful in the short term, but there is immediate relief as you swallow information like mad, and then you getto forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment when the time is up.” Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. “If you understand the material and have the ability to articulate (说出) your thoughts, they should be a breeze.”[H] How students ultimately handle stress may depend on their personaltest-taking abilities. There are people who always wait until the last minute, and make it much harder than it needs to be. And then there those who, not knowing what questions are coming at them, and having no resources to refer to, can freeze. And then there are we rare folks who fit both those descriptions.[I] Yes, my advanced age must factor into the equation (等式), in part because of my inability toaccess the information as quickly. As another returning student at Columbia, Kate Marber, toldme, “We are learning not only all this information, but essentially how to learn again. Ourfellow students have just come out of high school. A lot has changed since we were last inschool.”[J] If nothing else, the situation has given my college son and me something to share, When Iasked his opinion on this matter, he responded, “I like in-class exams because the time isalready reserved, as opposed to using my free time at home to work on a test,” he responded.It seems to me that a compromise would be receiving the exam questions a day or two inadvance, and then doing the actual test in class the ticking clock overhead.[K] Better yet, how about what one Hunter College professor reportedly did recently for her finalexam: She encouraged the class not to stress or even study, promising that, “It is going to be apiece of cake.” When the students came in, sharpened pencils in hand, there was not a bluebook in sight. Rather, they saw a large chocolate cake and they each were given a slice.36. Elderly students find it hard to keep up with the rapid changes in education.37. Some believe take-home exams may affect students' performance in other courses.38. Certain professors believe in-class exams are ultimately more helpful to students.39. In-class exams are believed to discourage cheating in exams.40. The author was happy to learn she could do some exams at home.41. Students who put off their work until the last moment often find the exams more difficult thanthey actually are.42. Different students may prefer different types of exams.43. Most professors agree whether to give an in-class or a take-home exam depends on type ofcourse being taught.44. The author dropped out of college some forty years ago.45. Some students think take-home exams will eat up their free time.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 and 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the “first-night” effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university’s Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, theparticipants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants’ brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46. What did researchers find puzzling about the first-night effect?A) To what extent it can trouble people. C) What circumstances may trigger it.B) What role it has played in evolution. D) In what way it can be beneficial.47. What do we learn about Dr. Yuka Sasaki doing her research?A) She found birds and dolphins remain alert while asleep.B) She found birds and dolphins sleep in much the same way.C) She got some idea from previous studies on birds and dolphinsD) She conducted studies on birds’ and dolphins’ sleeping patterns.48. What did Dr. Sasaki do when she first did her experiment?A) She monitored the brain activity of participants sleeping in a new environment.B) She recruited 35 participants from her Department of Psychological Sciences.C) She studied the differences between the two sides of participants’ brains.D) She tested her findings about birds and dolphins on human subjects.49. What did Dr. Sasaki do when re-running her experiment?A) She analyzed the negative effect of irregular tones on brains.B) She recorded participants’ adaptation to changed environment.C) She exposed her participants to two different stimuli.D) She compared the responses of different participants.50. What did Dr. Sasaki find about the participants in her experiment?A) They tended to enjoy certain tones more than others.B) They tended to perceive irregular beeps as a threat.C) They felt sleepy when exposed to regular beeps.D) They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 55 are based on the following passage.It’s time to reevaluate how women handle conflict at work. Being overworked or over-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men to feel exhausted? Nearly twice as many women than men ages 18-44 reported feeling “very tired” or “exhausted”, according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying "no." Women want to be able todo it all volunteer for school parties or cook delicious meals-and so their answer to any request is often “Yes, I can.”Women struggle to say “no” in the workplace for similar reasons, including the desire to be liked by their colleagues. Unfortunately, this inability to say "no" may be hurting women's heath as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want to be viewed as aggressive or disruptive at work. For example, there’s a problem that needs to be addressed immediately, resulting in a dispute over should be the oneto fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem-evenif that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have to be able to delegate and manage resources wisely – including staff expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.51. What does the author say is the problem with women?A) They are often unclear about the career goals to reach.B) They are usually more committed at home than on the job.C) They tend to be over-optimistic about how far they could go.D) They tend to push themselves beyond the limits of their ability.52. Why do working women of child-bearing age tend to feel drained of energy?A) They struggle to satisfy the demands of both work and home.B) They are too devoted to work and unable to relax as a result.C) They do their best to cooperate with their workmates.D) They are obliged to take up too many responsibilities.53. What may hinder the future prospects of career women?A) Their unwillingness to say “no”.B) Their desire to be considered powerful.C) An underestimate of their own ability.D) A lack of courage to face challenges.54. Men and woman differ in their approach to resolving workplace conflicts in that______.A) women tend to be easily satisfiedB) men are generally more persuasiveC) men tend to put their personal interests firstD) women are much more ready to compromise55. What is important to a good leader?A) A dominant personality. C) The courage to admit failureB) The ability to delegate. D) A strong sense of responsibility.Part Ⅳ Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese intoEnglish.

When the rats detect the smell, they stop and rub their legs to 34 a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to 35 , but for a rat it takes less than 20 minutes. This rat detection method doesn’t rely on specialist equipment. It is also more accurate—the rats are able to find more TB infections and, therefore, save more lives.A) associated B) examine C) indicate D) nuisanceE) peak F) preventing G) prohibiting H) sensitiveI) slight J) specify K) superior L) suspiciousM) tip N) treated O)visualSection BDirections: In this section, you are going to read a passage w ith ten statements a ttached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the informationis 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.Do In-Class Exams Make Students Study Harder?Research suggests they may study more broadly for the unexpected rather than search for answers.[A] I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.[B] Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly.[C] As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I did some of my own pollingamong students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. “That way they socialize over history outside the class, which wouldn’t happen without the pressure of an in-class exam,”he explained, “Furthermore, in-class exams force students to learn how to perform under pressure, an essential work skill.”[D] He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled “Introduction To Congress.” Some colleges have what they call an “honor code,” though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn’t just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me going.[E] Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school’s professors to refrain from take-hone exams. “Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries,”she told me.“Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention.”[F] Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-based one, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help. Vocational-type classes, such as computer science or journalism, on the other hand, are often more research-oriented and lend themselves to take-home testing. Chris Koch, who teaches “History of Broadcast Journalism” at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. “In my field, it’s not what you know—it’s what you know how to find out,” says Koch. “There is way too much information, and more coming all the time, for anyone to remember. I want my students to search out the answers to questions by using all the resources available to them.”[G] Students’test-form preferences vary, too, often depending on the subject and course difficulty. “I prefer take-home essays because it is then really about the writing, so you have time to edit and do more research,”says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, “I find the in-class ones are more stressful in the short term, but there is immediate relief as youswallow information like mad, and then you get to forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment when the time is up.”Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. “If you understand the material and have the ability to articulate (说出) your thoughts, they should be a breeze.”[H] How students ultimately handle stress may depend on their personal test-taking abilities. There are people who always wait until the last minute, and make it much harder than it needs to be. And then there those who, not knowing what questions are coming at them, and having no resources to refer to, can freeze. And then there are we rare folks who fit both those descriptions.[I] Yes, my advanced age must factor into the equation (等式), in part because of my inability to access the information as quickly. As another returning student at Columbia, Kate Marber, told me, “We are learning not only all this information, but essentially how to learn again. Our fellow students have just come out of high school. A lot has changed since we were last in school.”[J] If nothing else, the situation has given my college son and me something to share. When I asked his opinion on this matter, he responded, “I like in-class exams because the time is already reserved, as opposed to using my free time at home to work on a test,” he responded.It seems to me that a compromise would be receiving the exam questions a day or two in advance, and then doing the actual test in class the ticking clock overhead.[K] Better yet, how about what one Hunter College professor reportedly did recently for her final exam: She encouraged the class not to stress or even study, promising that, “It is going to be a piece of cake.” When the students came in, sharpened pencils in hand, there was not a blue book in sight. Rather, they saw a large chocolate cake and they each were given a slice.36. Elderly students find it hard to keep up with the rapid changes in education.37. Some believe take-home exams may affect students’ performance in other courses.38. Certain professors believe in-class exams are ultimately more helpful to students.39. In-class exams are believed to discourage cheating in exams.40. The author was happy to learn she could do some exams at home.41. Students who put off their work until the last moment often find the exams more difficult than they actually are.42. Different students may prefer different types of exams.43. Most professors agree whether to give an in-class or a take-home exam depends on type of course being taught.44. The author dropped out of college some forty years ago.45. Some students think take-home exams will eat up their free time.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 and 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the “first-night”effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can restwhile remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look,her team studied 35 healthy people as they slept in the unfamiliar environment of the university’s Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants’brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46. What did researchers find puzzling about the first-night effect?A) To what extent it can trouble people.B) What role it has played in evolution.C) What circumstances may trigger it.D) In what way it can be beneficial.47. What do we learn about Dr. Yuka Sasaki doing her research?A) She found birds and dolphins remain alert while asleep.B) She found birds and dolphins sleep in much the same way.C) She got some idea from previous studies on birds and dolphins.D) She conducted studies on birds’ and dolphins’ sleeping patterns.48. What did Dr. Sasaki do when she first did her experiment?A) She monitored the brain activity of participants sleeping in a new environment.B) She recruited 35 participants from her Department of Psychological Sciences.C) She studied the differences between the two sides of participants’brains.D) She tested her findings about birds and dolphins on human subjects.49. What did Dr. Sasaki do when re-running her experiment?A) She analyzed the negative effect of irregular tones on brains.B) She recorded participants’ adaptation to changed environment.C) She exposed her participants to two different stimuli.D) She compared the responses of different participants.50. What did Dr. Sasaki find about the participants in her experiment?A) They tended to enjoy certain tones more than others.B) They tended to perceive irregular beeps as a threat.C) They felt sleepy when exposed to regular beeps.D) They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 55 are based on the following passage.It’s time to reevaluate how women handle conflict at work. Being overworked or over-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men to feel exhausted? Nearly twice as many women than men ages 18-44 reported feeling “very tired” or “exhausted”, according to a recent study.This may not be surprising given that this is the age range when women have children. It’s also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying “no.” Women want to be able to do it all—volunteer for school parties or cook delicious meals—and so their answer to any request is often “Yes, I can.”Women struggle to say “no”in the workplace for similar reasons,including the desire to be liked by their colleagues. Unfortunately, this inability to say “no”may be hurting women’s heath as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don’t want to be viewed as aggressive or disruptive at work. For example, there’s a problem that needs to be addressed immediately, resulting in a dispute over who should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what’s the easiest and quickest way to resolve the problem—even if that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders—including staff have to be able to delegate and manage resources wiselyexpertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.51. What does the author say is the problem with women?A) They are often unclear about the career goals to reach.B) They are usually more committed at home than on the job.C) They tend to be over-optimistic about how far they could go.D) They tend to push themselves beyond the limits of their ability.52. Why do working women of child-bearing age tend to feel drained of energy?A) They struggle to satisfy the demands of both work and home.B) They are too devoted to work and unable to relax as a result.C) They do their best to cooperate with their workmates.D) They are obliged to take up too many responsibilities.53. What may hinder the future prospects of career women?A) Their unwillingness to say “no”.B) Their desire to be considered powerful.C) An underestimate of their own ability.D) A lack of courage to face challenges.54. Men and woman differ in their approach to resolving workplace conflicts in that ______.A) women tend to be easily satisfiedB) men are generally more persuasiveC) men tend to put their personal interests firstD) women are much more ready to compromise55. What is important to a good leader?A) A dominant personality.B) The ability to delegate.C) The courage to admit failure.D) A strong sense of responsibility.Part IV Translation (30 minutes)Directions:For this part, you are allowed 30 minutes to translate a passage f rom Chinese into English.

2017年12月大学英语四级真题及答案解析(全三套) 四级听力第一套：News Report 1A 9-year-old girl in New Mexico has raised more than $500 for her little brother who needs heart surgery in Houston, Texas this July. Addison Witulski's grandmother Kim Allred, said Addison probably overheard a conversation between family members talking about the funds needed to get her little brother to treatment. "I guess she overheard her grandfather and me talking about how we're worried about how we're going to get to Houston, for my grandson's heart surgery," said Allred. She decided to go outside and have a lemonade stand and make some drawings and pictures and sell them.” That's when Addison and her friends Erika and Emily Borden decided to sell lemonade for 50 cents a cup and sell pictures for 25 cents each.Before Allred knew it, New Mexico State Police Officers were among the many stopping by helping them reach a total of $568. The family turned to social media expressing their gratitude saying, "From the bottom of our hearts, we would like to deeply thank each and every person that stopped by!"1: Who did Addison raise the money for?2: How did Addison raise the money?1.D) Her little brother.2.B) By selling lemonade and pictures.News Report 2:Last week, France announced that the country will pave 621 miles of road with solar panels over the next five years with the goal of providing cheap, renewable energy to five million people. Called the Ward Way, the roads will be built through joint efforts with the French road building company Colas and the National Institute of Solar Energy. The companyspent the last five years developing solar panels that are only about a quarter of inch thick and are strong enough to stand up to heavy highway traffic without breaking or making the roads more slippery. The panels are also designed so that they can be installed directly on top of the existing roadways, making them relatively cheap and easy to install. France is the first country to kick around the idea of paving its roads with solar panels. In November 2015, the Netherlands completed a 229-foot long bike path paved with solar panels as a test for future projects. However, this is the first time a panel has been designed to be laid directly on top existing roads and the first project to install the panels on public highways.3: What was France’s purpose of constructing the Ward Way?4: What is special about the solar panels used in the Ward Way?3.B) Providing clean energy to five million people.4.C) They can be laid right on top of existing highways.News Report 3Lions have disappeared from much of Africa, but for the past few years scientists have wondered if the big cats were hanging on in remote parts of Sudan and Ethiopia. Continuous fighting in the region has made surveys difficult. But scientists released a report Monday documenting with hard evidence the discovery of "lost lions." A team with Oxford University’s Wildlife Conservation Research Unit, supported by a charity organization, spent two nights in November camping in a national park in northwest Ethiopia on the Ethiopia-Sudan border. The researchers set out six camera traps, capturing images of lions, and the identified lion tracks. The scientists concluded that lions are also likely to live in a neighboring national park across the border in Sudan. The International Union for Conservation of Nature had previously considered the area a "possible range" for the species, and local people had reported seeing lions in the area, but no one presented convincing evidence.5: What has made it difficult to survey lions in remote parts of Sudan and Ethiopia?6: What was the main purpose of the research?7: What did the researchers find in the national park?5.C)Endless fighing in the region.6.D)To find evidence of the lions'disappearance.7.A)Lions'tracks.Conversation OneM: I beg you’re looking forward to the end of this month. Aren’t you?W: Yes, I am. How did you know?M: David told me you had a special birthday coming up.W: Oh, yes. That’s right. This year would be my golden birthday.M: What does that mean? I’ve never heard of a golden birthday.W: I’ve actually just learned of this concept myself. Fortunately, just in time to celebrate. A golden or lucky birthday is when one turns the age of their birth date. So, for example, my sister’s birthday is December 9th and her golden birthday would have been the year she turns 9 years old. Come to think of it , my parents did throw her a surprise party that year. M: Intere sting. Too bad I missed mine. My golden birthday would’ve been four years ago.I assumedly got a big plan then.W: Actually yes. My husband is planning a surprise holiday for the two of us next week. I have no idea what he’s gotten in mind, but I’m excited to find out. Has he mentioned anything to you?M: He might have.W: Anything you’d like to share? I’m dying to know what kind of trip he has planned where we’re going.M: Yeah, nothing at all.W: Not a clue. Hard to imagine, isn’t it! Though I must say, I think it has been even more fun keeping the secret for me the past few weeks.M: I’m sure both of you will have a fantastic time. Happy golden birthday! I can’t wait to hear all about it when you get back.8. What does the woman looking forward to?9. W hat did the woman’s parents do on her sister’s lucky birthday?10. What is the woman eager to find out about?11. What does the man say at the end of the conversation?8.D) Her "lucky brithday".9.A) Threw her a superise party.10.C) The trip her husband has planned.11.B) He is eager to learn how the couple's holiday turns out.Conversation TwoW: Mr. Green, What do you think makes a successful negotiator?M: Well, It does hard to define, but I think successful negotiators have several things in common. They are always polite and rational people, they are firm, but flexible. They can recognize power and know how to use it. They are sensitive to the dynamics in the negotiation, the way it raises and falls, and how may change the direction. They project the image of confidence, and perhaps most importantly, they know when to stop.W: And what about an unsuccessful negotiator?M: Well, this probably all of us when we start out. We are probably immature and over-trusting, too emotional or aggressive. We are unsure of ourselves and want to be liked by everyone. Good negotiators learn fast, pool negotiators remain like that and go on losing negotiations,W: In your opinion, can the skills of negotiation be taught?M: Well, you can teach someone how to prepare for negotiation. There perhaps six stages in every negotiation, get to know the other side, stay your goals, start the process, clarify there is a disagreement or conflict, reassess your position, making acceptable compromise, and finally reach some agreements and principals. These stages can be studied, and strategies to be used in each can be planned before-hand. But I think the really successfulnegotiator is probably born with the sixth sense that may respond properly to the situation at hand.W: The artistic sense you just described?M: Yes, that’s right12. What’s the man say about good negotiators?13. What does the man say, maybe the most important thing to a successful negotiator?14. How is a good negotiator different from a poor one?15. What’s th e first stage of a negation according to the man?12. A) They are sensitive to the dynamics of a negotiation.13. B) They know when to stop.14. C) They learn quickly.15. D) Get to know the other side.Passage OneSome people wonder why countries spend millions of dollars on space projects. They want to know how space research helps people on earth. Actually, space technology helps people on earth every day. This is called spin-off technology. Spin-off technology is space technology that is now used on earth. In early space programs, such as the Apollo missions of the 1960s and 1970s and in the space shuttle missions today, scientists developed objects for the astronauts to use on the moon and in space. We now use some of these objects every day. For example, we have quartz crystal clocks and watches accurate to within one minute a year. We purify the water we drink with the water filter designed for the astronauts to use in space. The cordless hand held tools we use in our homes, such as vacuum cleaners, flashlights, drills came from the technology of these early space programs. On cold winter days, we can stay warm with battery-operated gloves and socks, especially made coats and jackets. All the clothes are similar to the space suits designs that kept astronauts comfortable in the temperatures of the moon, in our spin offs from space technology. These products are only a few examples of the many ways spacetechnology helps us in our everyday lives. No one knows how new spin off technology from the international space station will help us in the future.16. What do some people want to know about space exploration?17. What did scientist do for the space shuttle missions?18. What does the speaker say about the quartz crystal clocks and watches?16. D) How space research benefits people on Earth.17. B) They developed objects for astronauts to use in outer space.18. C) They are extremely accurate.Passage TwoWell, if I could get back in history and live, I'd like to get back to the 18th century and perhaps in colonial America in Yankee new England where one of my ancestors lived, because it was the beginning of something. By the 18th century, there was a feeling of community that had grown. My ancestor was the preacher traveling around countryside. People lived in small communities. It was fisherman and farmers who provided fresh food that tasted and looked like food. Unlike today’s supermarkets, and there were small towns and New York wasn't that far away. I'm deeply attached to the puritan tradition not in a religious sense. But they believed in working for something, working for goals. And I like that. They worked hard at whatever they did, but they had a sense of achievement. They believed in goodness, in community, and helping one another. I love the colonial fabrics or the silver works, the furnishings, the combination of elegance simplicity. I'd love it. The printing, the books, I’m very attached to all that kind of thing. That may not all be very entertaining in the modern sense of the world, but I would have enjoyed spending my evenings in that environment, discussing new ideas, building a new world, and I can see myself sitting on a small chair by the fire doing needle work.19. Why does the speaker say she would like to go back and live in the 18th century America?20. What does the speaker say about the Puritans?21. What would the speaker like doing if she could go back to the past?19. C)It marked the beginning of something new.20. A)They believed working for goals.21. D)Doing needlework by the fire.Passage threeIf you are lost in the woods, a little knowledge concerned with some people called a hardship into an enjoyable stay away from the troubles of modern society. When you think you're lost,sit down on the log or rock, or lean against the tree, and recite something you are memorized to bring your mind to the point where is under control. Don’t run blindly if you must move, don't follow stream unless you know it, and in that case you're not lost. Streams normally flow through wide land before they reach a lake or river though there are more eatable plants, there may also be wild animals, poisonous snakes, and other hazards. Many experts feel it is the wisest to walk up hill. At the top of most hills and mountains are trails living back to civilizations. If there are no trails, you're much easier to be seen on top of the hill. And you may even spot the highway or railroad from this point. Nowadays, the first way some of you search for you is by air. In the wide lands or in dense grass, we're very hard to spot. Anytime you are going to the woods, somebody should know where you're going, and when you are expected to return, also when someone comes to looking, you should be able to signal to them.22. What does the speaker advise you to do first if you are lost in the woods?23. What will happen if you follow an unknown stream in the woods?24. What do many experts think is the wisest thing to do if you're lost in the woods?25. What should you do before you go into the woods?22. C) Sit down and try to calm yourself23. B) You may expose yourself to unexpected dangers.24. D) Walk uphill.25. A) Inform somebody of your plan.四级听力第二套：答案：1.D) It has got one of its injured.2.C) Its videos were posted on social media.3.A) The distance travelled.4.B) Gas consumption is soaring.5.B) He helps a stranger to carry groceries to his car.6.C) He raised a large sum of money for him.7.A) He works hard to support his family.8.

To be curious, we need to realize first of all thatthere are many things we don’t know.H）Moreover,in order to be curious , ” you have to aware of a gap in your knowledge in thefirst place.” Although Leslie perhaps paints a bit broadly in contending thatmost of usare unaware of how much we don’t know, he’s surely right to pointout that the problem is gro wing:”Google can give us the powerful illusion thatall questions have definite answers.”37. According to Leslie, curiosity is essential to one’ssuccess.D) Thejournalist Ian Leslie, in his new and enjoyable book Curious: The Desire to Know and Why Yo ur Future Depends on It,insists that the answer to that last question is “Yes”. Leslie argues thatcuriosity is a much-overlooked human virtue, crucial to our success, and thatwe are losing it.38. We should feel happy when we pursue knowledge forknowledg e’s sake.O) All of which brings us back to Goodelland the Christie case and Benghazi. Each critic in those examples is charging,in a different way, that someone in authority is intentionally being incurious.I leave it to the reader's political preference to decide which, if any,charges should stick. But let’s be careful about demanding curiosity about theother side’s weaknesses and remaining determinedly incurious about our own. Weshould be delighted to pursue knowledge for its own sake—even when what we findout is something we didn't particularly want to know.39. Political leaders’ lack of curiosity will result inbad consequences.M) AlthoughLeslie’s book isn’t about politics, he doesn’t entirely shy away from theproblem. Political leaders, like leaders of other organizations, should becurious. They should ask questions at crucial moments. There are seriousconsequences, he warns, in not wanting to know.40. There are often accusations about politicians’ andthe media’s l ack of curiosity to find out the truth.B) Theaccusation of incuriosity is one that we hear often, carrying the suggestionthat there is something wrong with not wanting to search out the truth. “I havebeen bothered for a long time about the curious lac k of curiosity,” said aDemocratic member of the New Jersey legislature back in July, referring to aninsufficiently inquiring attitude on the part of an assistant to New JerseyGovernor Chris Christie who chose not to ask hard questions about the GeorgeWashi ngton Bridge traffic scandal. “Isn’t the mainstream media the least bitcurious about what happened?” wrote conservative writer Jennifer Rubin earlierthis year, referring to the attack on Americans in Benghazi, Libya.41. The less curious a child is, the less knowledge thechild may turn out to have.L) Schooleducation, he warns, is often conducted in a way that makes children incurious.Children of educated and upper-middle-class parents turn out to be far morecurious, even at early ages, than children of working class and lower classfamilies. That lack of curiosity produces a relative lack of knowledge, and thelack of knowledge is difficult if not impossible to compensate for later on.42. It is widely accepted that academic accomplishmentlies in both intelligence and diligence.K) Citingthe work of psychologists and cognitive（认知的）scientists, Leslie criticizes the received wisdomthat academic success is the result of a combination of intellectual talent andhard work. Curiosity, he argues, is the third key factor—and a difficult one topreserve. If not cultivated, it will not survive：“Childhood curiosity is a collaboration between childand adult. The surest way to kill it is to leave it alone.”43. Visiting a bookshop as curiosity leads us can be agood way to entertain ourselves.J) Somewhatnostalgically（怀旧地），he quote John Maynard Keynes’s justlyfamous words of praise to the bookstore:”One should enter it vaguely, almost ina dream, and allowwhat is there freely to attract and influence the eye. Towalk the rounds of the bookshops, dipping in as curiosity dictates, should bean afternoon’s entertainment.” If only!44. Both the rise of the Internet and reduced appetitefor literary fiction contribute to people’s declining curiosity.G) Lesliepresents considerable evidence for the proposition that the society as a wholeis growing less curious. In the U.S. and Europe, for example, the rise of theInternet has led to a declining consumption of news from outside the reader’sborders. But not e verything is to be blamed on technology. The decline ininterest in literary fiction is also one of the causes identified by Leslie.Reading literary fiction, he says, make us more curious.45.Mankind wouldn’t be so innovative without curiosity.F) Why isthis a problem? Because without curiosity we will lose the spirit of innovationand entrepreneurship. We will see unimaginative governments and dyingcorporations make disastrous decisions. We will lose a vital part of what hasmade humanity as a whole so successful as a species.仔细阅读46.

Now, researchers have found a (27)_______ingredient in residue (残留物）from 5,000-year-old beer brewing equipment. While digging two pits at a site in the central plains of China, scientists discovered fragments from pots and vessels.

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.The Blessing and Curse of the People Who Never ForgetA handful of people can recall almost every day of their lives in enormous detail—and after years of research, neuroscientists (神经科学专家) are finally beginning to understand how they do it.[A] For most of us, memory is a mess of blurred and faded pictures of our lives. As much as we would like to cling on to our past, even the saddest moments can be washed away with time.[B] Ask Nima Veiseh what he was doing for any day in the past 15 years, however, and he will give you the details of the weather, what he was wearing, or even what side of the train he was sitting on his journey to work. “My memory is like a library of video tapes, walk-throughs of every day of my life from waking to sleeping,” he explains.[C] Veiseh can even put a date on when those tapes started recording: 15 December 2000, when he met his first girlfriend at his best friend's 16th birthday party. He had always had a good memory, but the thrill of young love seems to have shifted a gear in his mind: from now on, he would start recording his whole life in detail. “I could tell you everything about eve ry day after that.”[D] Needless to say, people like Veiseh are of great interest to neuroscientists hoping to understand the way the brain records our lives. A couple of recent papers have finally opened a window on these people’s extraordinary minds. And such research might even suggest ways for us all to relive our past with greater clarity.[E] “Highly superior autobiographical memory”（or HSAM for short) first came to light in the early 2000s, with a young woman named Jill Price. Emailing the neuroscientist and memory researcher Jim McGaugh one day, she claimed that she could recall every day of her life since the age of 12. Could he help explain her experiences?[F] McGaugh invited her to his lab, and began to test her: he would give her a date and ask her to tell him about the world events on that day. True to her word, she was correct almost every time.[G] It didn’t take long for magazines and documentary film-makers to come to understand her “total recall”，and thank to the subsequent media interest, a few dozen other subjects (including Veiseh) have since come forward and contacted the team at the University of California, Irvine.[H] Interestingly, their memories are highly self-centred: although they can remember “autobiographical” life events in e xtraordinary detail, they seem to be no better than average at recalling impersonal information, such as random (任意选取的）lists of words. Nor are they necessarily better at remembering a round of drinks, say. And although their memories are vast, they are sti ll likely to suffer from “false memories”.Clearly, there is no such thing as a “perfect” memory—their extraordinary minds are still using the same flawed tools that the rest of us rely on. The question is, how?[I] Lawrence Patihis at the University of Southern Mississippi recently studied around 20 people with HSAM and found that they scored particularly high on two measures: fantasy proneness (倾向)and absorption. Fantasy proneness could be considered a tendency to imagine and daydream, whereas absorption is the tendency to allow your mind to become fully absorbed in an activity to pay complete attention to the sensations (感受)and the experiences. “I’m extremely sensitive to sounds, smells and visual detail,” explain s Nicole Donohue, who has taken part in many of these studies. “I definitely feel things more strongly than the average person.”[J] The absorption helps them to establish strong foundations for recollection, says Patihis, and the fantasy proneness means that they revisit those memories again and again in the coming weeks and months. Each time this initial memory trace is “replayed”, it becomes even stronger. In some ways, you probably go through that process after a big event like your wedding day,but the difference is that thanks to their other psychological tendencies, the HSAM subjects are doing it day in, day out, for the whole of their lives.[K] Not everyone with a tendency to fantasise will develop HSAM, though, so Patihis suggests that something mus t have caused them to think so much about their past. “Maybe some experience in their childhood meant that they became obsessed (着迷）with calendars and what happened to them,”says Patihis.[L] The people with HSAM I’ve interviewed would certainly agree that it can be a mixed blessing. On the plus side, it allows you to relive the most transformative and enriching experiences. Veiseh, for instance, travelled a lot in his youth. In his spare time,he visited the local art galleries, and the paintings are now lodged deep in his autobiographical memories.[M] “Imagine being able to remember every painting, on every wall, in every gallery space, between nearly 40 countries，” he says. “That’s a big education in art by itself.” With this comprehensive knowledge of the history of art, he has since become a professional painter.[N] Donohue, now a history teacher, agrees that it helped during certain parts of her education. “I can definitely remember what I learned on certain days at school. I could imagine what the tea cher was saying or what it looked like in the book.”[O] Not everyone with HSAM has experienced these benefits, however. Viewing the past in high definition can make it very difficult to get over pain and regret. “It can be very hard to forget embarrassing moments,” says Donohue. “You feel the same emotions—it is just as raw, just as fresh... You can’t turn off that stream of memories, no matter how hard you try.” Veiseh agrees. “It is like having these open wounds—they are just a part of you,” he says.[P] This means they often have to make a special effort to lay the past to rest. Bill, for instance, often gets painful “flashbacks”，in which unwanted memories intrude into his consciousness, but overall he has chosen to see it as the best way of avoiding repeating the same mistakes. “Some people are absorbed in the past but not open to new memories, but that’s not the case for me. I look forward to each day and experiencing something new.”36.People with HSAM have the same memory as ordinary people when it comes to impersonal information.37.Fantasy proneness will not necessarily cause people to develop HSAM.38.Veiseh began to remember the details of his everyday experiences after he met his first young love.39.Many more people with HSAM started to contact researchers due to the mass media.40.People with HSAM often have to make efforts to avoid focusing on the past.41.Most people do not have clear memories of past events.42.HSAM can be both a curse and a blessing.43.A young woman sought explanation from a brain scientist when she noticed her unusual memory.44.Some people with HSAM find it very hard to get rid of unpleasant memories.45.A recent study of people with HSAM reveals that they are liable to fantasy and full absorption in an activity.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 2with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.The phrase almost completes itself: midlife crisis. It’s the stage in the middle of the journey when people feel youth vanishing, their prospects narrowing and death approaching.There’s only one problem with the cliche (套话).It isn’t true.“In fact, there is almost no hard evidence for midlife crisis other than a few small pilot studies conducted decades ago,” Barbara Hagerty writes in her new book, Life Reimagined. The vast bulk of the research shows that there may be a pause, or a shifting of gears in the 40s or 50s, but this shift “can be exciting, rather than terrifying”.Barbara Hagerty looks at some of the features of people who turn midlife into a rebirth. They break routines, because “autopilot is death”. They choose purpose over happiness一having a clear sense of purpose even reduces the risk of Alzheimer’s disease. They give priority to relationships, as careers often recede(逐渐淡化).Life Reimagined paints a picture of middle age that is far from gloomy. Midlife seems like the second big phase of decision-making. Your identity has been formed; you’ve built up your resources; and now you have the chance to take the big risks precisely because your foundation is already secure.Karl Barth described midlife precisely this way. At middle age, he wrote, “the sowing is behind; now is the time to reap. The run has been taken; now is the time to leap. Preparation has been made; now is the time for the venture of the work itself.”The middle-aged person, Barth continued, can see death in the distance, but moves with a “measured haste” to get big new things done while there is still time.What Barth wrote decades ago is even truer today. People are healthy and energetic longer. We have presidential candidates running for their first term in office at age 68, 69 and 74. A longer lifespan is changing the narrative structure of life itself. What could have been considered the beginning of a descent is now a potential turning point—the turning point you are most equipped to take full advantage of.46.What does the author think of the phrase “midlife crisis”?A) It has led to a lot of debate. B) It is widely acknowledged.C) It is no longer fashionable. D) It misrepresents real life.47.How does Barbara Hagerty view midlife?A) It may be the beginning of a crisis.B) It can be a new phase of one’s life.C) It can be terrifying for the unprepared.D)It may see old-age diseases approaching.48.How is midlife pictured in the book Life Reimagined?A) It can be quite rose.B) It can be burdensome.C) It undergoes radical transformation.D) It makes for the best part of one’s life.49.According to Karl Barth, midlife is the time_______.A) to relax B) to matureC) to harvest D) to reflect50.What does the author say about midlife today?A) It is more meaningful than other stages of life.B) It is likely to change the narrative of one’s life,C) It is more important to those with a longer lifespan.D)It is likely to be a critical turning point in one’s life.Passage TwoQuestions 51 to 55 are based on the following passage.In spring, chickens start laying again, bringing a welcome source of protein at winter’s end. So it’s no surprise that cultures around the world celebrate spring by honoring the egg.Some traditions are simple, like the red eggs that get baked into Greek Easter breads. Others elevate the egg into a fancy art, like the heavily jewel-co vered “eggs” that were favored by the Russians starting in the 19th century.One ancient form of egg art comes to us from Ukraine. For centuries, Ukrainians have been drawing complicated patterns on eggs. Contemporary artists have followed this tradition to create eggs that speak to the anxieties of our age: Life is precious, and delicate. Eggs are, too.“There’s something about their delicate nature that appeals to me,” says New Yorker cartoonist Roz Chast. Several years ago, she became interested in eggs and learned the traditional Ukrainian technique to draw her very modem characters. “I’ve broken eggs at every stage of the process—from the very beginning to the very, very end.”But t here’s an appeal in that vulnerability. “There’s part of this sickening horror of knowing you’re walking on the edge with this, that I kind of like, knowing that it could all fall apart at any second.” Chast’s designs, such as a worried man alone in a tiny rowboat, reflect that delicateness.Traditional Ukrainian decorated eggs also spoke to those fears. The elaborate patterns were believed to offer protection against evil.“There’s an ancient legend that as long as these eggs are made, evil will not prevai l in the world,” says Joan Brander, a Canadian egg-painter who has been painting eggs for over 60 years, having learned the art from her Ukrainian relatives.The tradition, dating back to 300 B.C., was later incorporated into the Christian church. The old symbols, however, still endure. A decorated egg with a bird on it, given to a young married couple, is a wish for children. A decorated egg thrown into the field would be a wish for a good harvest.51.Why do people in many cultures prize the egg?A) It is a welcome sign of the coming of spring.B) It is their major source of protein in winter.C) It can easily be made into a work of art.D) It can bring wealth and honor to them.52.What do we learn about the decorated “eggs” in Russia?A) They are shaped like jewel cases.B) They are cherished by the rich.C) They are heavily painted in red.D) They are favored as a form of art.53.Why have contemporary artists continued the egg art tradition?A) Eggs serve as an enduring symbol of new life.B) Eggs have an oval shape appealing to artists.C) Eggs reflect the anxieties of people today.D) Eggs provide a unique surface to paint on.54.Why does Chast enjoy the process of decorating eggs?A) She never knows if the egg will break before the design is completed.B) She can add multiple details to the design to communicate her idea.C) She always derives great pleasure from designing something new.D) She is never sure what the final design will look like until the end.55.What do we learn from the passage about egg-painting?A) It originated in the eastern part of Europe.B) It has a history of over two thousand years.C) It is the most time-honored form of fancy art.D) It is especially favored as a church decoration.Part IV Translation (30 minutes) Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

over history outside the class, which wouldn’t class exam,” he explained, happen without the pressure of an in-“Furthermore, in-class exams force students to learn how to perform under pressure, and essential work skill.”[D] He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled nor “Introduction To Congress.” Some colleges have what they call an “ho code,” though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn’t just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me going. [E] Following the Harvard scandal, Mary Miller, the former dean of fessors to students at Yale, made an impassioned appeal to her school’s prorefrain from take-hone exams. “Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries,” she told me. “Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention.”[F] Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-based one, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help. V

logical Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants’ brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球半球) of their brains did not sleep nearly as deeply as their right hemispheres did. Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found. 46. What did researchers find puzzling about the first-night effect? A) To what extent it can trouble people. C) What circumstances may trigger it. B) What role it has played in evolution. D) In what way it can be beneficial. 47. What do we learn about Dr. Yuka Sasaki doing her research? A) She found birds and dolphins remain alert while asleep. B) She found birds and dolphins sleep in much the same way. C) She got some idea from previous studies on birds and dolphins D) She conducted studies on birds’ and dolphins’ sleeping patterns.48. What did Dr. Sasaki do when she first did her experiment? A) She monitored the brain activity of participants sleeping in a new environment. B) She recruited 35 participants from her Department of Psychological Sciences. C) She studied the differences between the two sides of participants’ brains. D) She tested her findings about birds and dolphins on human subjects. 49. What did Dr. Sasaki do when re-running her experiment? A) She analyzed the negative effect of irregular tones on brains. B) She recorded participants’ adaptation to changed environment.C) She exposed her participants to two different stimuli. D) She compared the responses of different participants. 50. What did Dr. Sasaki find about the participants in her experiment? A) They tended to enjoy certain tones more than others. B) They tended to perceive irregular beeps as a threat. C) They felt sleepy when exposed to regular beeps. D) They differed in their tolerance of irregular tones. Passage Two Questions 51 to 55 are based on the following passage. It’s time to reevaluate how women handle conflict at work. Being overworked or over-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals. Did you know women are more likely than men to feel exhausted? 44 reported feeling “very Nearly twice as many women than men ages 18-tired” or “exhausted”, according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying "no." Women want to be able todo it all volunteer for school parties or cook delicious meals-and so their answer to any request is often “Yes, I can.”Women struggle to say “no” in the workplace for similar reasons, including the desire to be liked by their colleagues. Unfortunately, this inability to say "no" may be hurting women's heath as well as their career. At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want to be viewed as aggressive or disruptive at work. For example, there’s a problem that needs to be addressed immediately, resulting in a dispute over should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem-even if that means doing the boring work themselves. This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have – including staff to be able to delegate and manage resources wisely expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively. 51. What does the author say is the problem with women? A) They are often unclear about the career goals to reach. B) They are usually more committed at home than on the job. C) They tend to be over-optimistic about how far they could go. D) They tend to push themselves beyond the limits of their

2017年12月大学英语四级真题试卷（一）作文1.Directions: For this part, you are allowed 30 minutes to write a short essay on how to best handle the relationship between parents and children. You should write at least 120 words but no more than 180 words.Communication Is the Best Gift for ParentsThe relationship between parents and children is an eternal and universal topic for mankind. Our relationship with parents might be different at different ages. And for young people at their 20s, I think it will depend more on what children do.The reason why I say so is that as we grow up, our parents who were our idols before gradually get old and even out-dated. However hard efforts they make, they could not catch up with our steps, leading to the so-called invisible generation gap. Thus, if we cannot slow down our pace, there will definitely be an awkward silence between parents and us, which is not rare now. As a result, young people should talk more with parents to share our feelings and to understand each other better.Everyone wants loving parents who are open and supportive. Only through frequent communication with them, can we establish such a harmonious relationship.解析：短篇新闻2.(D)A. By taking pictures for passers-by.B. Her grandmother.C. Her friend Erika.D.
