2013年12月第1套真题 深度解析

2013年12月四级真题及答案（第1套）Section BDirections: 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.The Gatais used to frown when they received power bills that routinely topped $200. Last September the couple moved into a 1,500-square-foot home in Premier Gardens, a subdivision of 95 "zero-energy homes"(ZEH)just outside town. Now they're actually eager to see their electricity bills. The grand total over the 10 months they've lived in the three-bedroom house: $ 75. For the past two months they haven't paid a cent.ZEH communities are the leading edge of technologies that might someday create houses that produce as much energy as they consume. Premier Gardens is one of a half-dozen subdivisions in California where every home cuts power consumption by 50% , mostly by using low-power appliances and solar panels.Aside from the panels on the roof, Premier Gardens looks like a community of conventional homes. But inside, special windows cut power bills by blocking solar heat in summer and retaining indoor warmth in winter.The rest of the energy savings comes from the solar units. They don't just feed the home they serve. If they generate more power than the home is using, the excess flows into the utility's power grid(电网). The residents are billed by "net metering" : they pay for the amount of power they tap off the grid, less the kilowatts(千瓦)they feed into it. If a home generates more powerthan it uses, the bill is zero.That sounds like a bad deal for the power company, but it's not. Solar homes produce the most power on the hot sunny afternoons when everyone rushes home to turn up the air conditioner. " It helps us lower usage at peak power times," says solar expert Mike Keesee. " That lets us avoid building costly plants or buying expensive power at peak usage time. "What's not to like? Mostly the costs. The special features can add $ 25,000 or more to the purchase price of a house. Tax breaks bring the cost down, especially in California, but in many states ZEHs can be prohibitively expensive. For the consumer, it's a matter of paying now for the hardware to save later on the utilities.58．Why are the Gatais eager to see their electricity bills now?A．They want to see how much they have saved.B．They want to cut down their utility expenses.C．They want to know if they are able to pay.D．They want to avoid being overcharged.59．What is special about the ZEH communities?A．They have created cutting-edge technologies.B．They aim to be self-sufficient in power supply.C．They are subdivided into half a dozen sections.D．They are built in harmony with the environment.60．How are the residents in the ZEH communities billed for electricity use?A．They are only charged for the amount of power they consume on rainy days.B．They needn't pay a single cent for their power consumption on sunny days.C．They only pay for the excess power that flows into theutility's power grid.D．They pay for the electricity from the grid less their home-generated power.61．What does the "net metering" practice mean to the power company?A．More pressure at peak time.B．Less profits in the short term.C．Increased electricity output.D．Reduced operational costs.62．The author believes that buying a house in a ZEH community______.A．is but a dream for average consumersB．gives the owner substantial tax benefitsC．is a worthy investment in the long runD．contributes to environmental protectionRomantic love has clear evolutionary roots but our views about what makes an ideal romantic relationship can be swayed by the society we live in. So says psychologist Maureen O'Sullivan from the University of San Francisco. She suggests that humans have always tried to strengthen the pair-bond to maximise(使最大化)reproductive success.Many societies throughout history and around the world today have cultivated strong pressures to stay married. In those where ties to family and community are strong, lifelong marriages can be promoted by practices such as the cultural prohibition of divorce and arranged marriages that are seen as a contract between two families, not just two individuals. In modern western societies, however, the focus on individuality and independence means that people are less concerned about conforming to(遵守)the dictates of family and culture. In theabsence of societal pressures to maintain pair-bonds, O'Sullivan suggests that romantic love has increasingly come to be seen as the factor that should determine who we stay with and for how long. " That's why historically we see an increase in romantic love as a basis for forming long-term relationships," she says.According to O'Sullivan culture also shapes the sorts of feelings we expect to have, and actually do experience, when in love. Although the negative emotions associated with romantic love—fear of loss, disappointment and jealousy—are fairly consistent across cultures, the positive feelings can vary. " If you ask Japanese students to list the positive attributes they expect in a romantic partner, they rate highly things like loyalty, commitment and devotion," says O'Sullivan. " If you ask American college women, they expect everything under the sun: in addition to being committed, partners have to be amusing, funny and a friend. "We judge a potential partner according to our specific cultural expectations about what romantic love should feel like. If you believe that you have found true romance, and your culture tells you that this is what a long-term relationship should be based on, there is less need to rely on social or family pressures to keep couples together, O'Sullivan argues.63．What does the author say about people's views of an ideal romantic relationship? A．They vary from culture to culture.B．They ensure the reproductive success.C．They reflect the evolutionary process.D．They are influenced by psychologists.64．We can infer from the passage that strong family and community ties______.A．largely rely on marriage contractsB．can contribute to stable marriagesC．often run counter to romantic loveD．make divorces virtually unacceptable65．Without social pressures to keep pair-bonds, romantic love______.A．will be a substitute for marriage in human relationships B．plays a key role in maintaining long-term relationships C．is likely to replace the dictates of family and societyD．is a way to develop individuality and independence66．O'Sullivan believes that when people from different cultures fall in love, ______.A．they expect different things from their partnerB．they tend to exaggerate each other's positive qualitiesC．they often fail to see each other's negative qualitiesD．they lay more emphasis on commitment and devotion 67．We can conclude from the passage that______.A．cultural differences often tear apart a family built on romantic loveB．marriages are hard to sustain without social or family pressuresC．romantic love is becoming increasingly important in family relationshipsD．romantic love tends to yield where family or social pressures are strongPassage OneQuestions 56 to 60 are based on the following passage.In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front ofus.Studies have shown, for instance, that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual cues, like plate size and lighting, have been shown to affect portion size and consumption.A new study suggested that our short-term memory also may play a role in appetite. Several hours after a meal, people’s hunger levels were predicted not by how much they’d eaten but rather by how much food they’d seen in front of them—in other words, how much they remembered eating.This disparity (差异) suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal, says Jeffrey M. Brunstrom, a professor of experimental psychology at the University of Bristol.“Hunger isn’t controlled solely by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal,”Brunstrom says. “This shows that the relationship between hunger and food intake is more complex than we thought.”These findings echo earlier research that suggests our perception of food can sometimes tric k our body’s response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie (卡路里) milkshake on two separate occasions produced different levels of hunger-related hormones (荷尔蒙), depending on whether the shake’s label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they’d consumed a higher-calorie shake.What does this mean for our eating habits? Although it hardly seems practical to trick ourselves into eating less, the new findings do highlight the benefits of focusing on our food and avoiding TV and multitasking while eating.The so-called mindful-eating strategies can fight distractions and helpus control our appetite, Brunstrom says.注意：此部分试题请在答题卡2上作答。

Ways to Get Over Information ExplosionAs a famous saying goes, “A wealth of information creates a poverty of attention”. Nowadays we are in the Information Age. Some people keep complaining about distraction by the information explosion.Admittedly, the new information age has brought us so much convenience that we are allowed to get enough information just with a simple click sitting in front of the computers. Nevertheless, we are also confused, annoyed, distracted and upset by an incredibly large quantity of information. For example, when searching for something online, people are easily carried away by irrelevant information and forget their original plan. Besides, some information often turns out to be useless and actually advertisement. Therefore, it can be time-consuming and troublesome to search information online.Then what we can do to avoid being distracted by irrelevant information? Here I have some useful tips: Firstly, make a list of what you really want before your searching. This will help you to refuse some appealing, yet irrelevant information. Secondly, find some trustful and professional sources or websites and then save and categorize them. In this case, you can easily leave some ads and useless information behind.【点评】本次作文主题围绕“信息爆炸给大众带来的困扰”，难度较小。

Twenty years ago, computers were 28_________, but they were very large and extremely expensive. Few, if any, 29________ purchased computers for home use. Over they years, the price of the “guts” of a computer --- its memory --- has declined to less than a thousandth of the price per unit of memory that prevailed twenty years ago. This is the main reason why computers cost so much less today than they used to. 31_____ memory circuitry that is small enough to fit into the portable personal computers that many of us own and use. 32______, as the price of computation has declined the average consumer and business have spent more on purchasing computers.33________, improved agricultural technology, hybrid(杂交) seeds, 34________ animal breeding, and so on have vastly increased the amount of output a typical farmer can produce. The prices of goods such as meats and grains have fallen sharply relative to the prices of most other goods and services. As agricultural prices have fallen, many households have decreased their total expense on food. Even though the 35______ of a product purchased generally increases when its price falls, total expenses on it may decline.Part III Reading Comprehension （40 minutes）Section ATo get a sense of how women have progressed in science. Take a quick tour of the physics department at the University of California, Berkeley. This is a storied place, the 36_______ some of the most important discoveries in modern science---starting with Ernest Lawrence’s invention of the cyclotron(回旋加速器) in 1931. a generation ago, female faces were 37_______ and, even today, visitors walking through the first floor of LeConte Hall will see a full corridor of exhibits 38_______ the many distinguished physicists who made history here, 39_______ all of them white makes.But climb up to the third floor and you’ll see a 40______ display. There, among the photos of current faculty members and students, are portraits of the 41________head of the department, Marjorie Shapiro, and four other women whose research 42_______ everything from the mechanics of the universe to the smallest particles of matter. A sixth woman was hired just twoweeks ago. Although they’re still only about 10 percent of the physics faculty, women are clearly a presence here. And the real 43_______ may be in the smaller photos to the right: graduate and undergraduate students, about 20 percent of them female. Every year Berkeley sends its fresh female physics PhDs to the country’s top universities. That makes Shapiro optimistic, but also 44______, “I believe things are getting better,”she says, “but they’re not getting better as 45________ as I would like.”A circumstanceB confidenceC coversD currentE dealsF differentG exposing H fast I honoringJ hope K presently L rareM realistic N site O virtuallySection BDirections: In this section, you are going to read 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.Is College a Worthy Investment?A) Why are we spending so much money on college? And why are we so unhappy about it? We allseem to agree that a college education is wonderful, and yet strangely we worry when we see families investing so much in this supposedly essential good. Maybe it’s time to ask a question that seems almost sacrilegious(大不敬的): is all this investment in college education really worth it?B) The answer, I fear, is no. for an increasing number of kids, the extra time and money spentpursuing a college diploma will leave them worse off than they were before they set foot on campus.C) For my entire adult life, a good education has been the most important thing for middle-classhouseholds. My parents spent more educating my sister and me than they spent on their house, and they’re not the only ones…and, of course, for an increasing number families, most of the cost of their house is actually the cost of living in a good school district. Questioning the value of a college education seems a bit like questioning the value of happiness, or fun.D) The average price of all goods and services has risen about 50 percent. But the price of acollege education has nearly doubled in that time. Is the education that today’s students are getting twice as good? Are new workers twice as smart? Have they become somehow massively more expensive to education?E) Perhaps a bit, Richard V edder, an Ohio University economics professor, says, “I look at thedata, and I see college costs rising faster then inflation up the mid-1980s by 1 percent a year.Now I see them rising 3 to 4 percent a year over inflation. What has happened? The federal government has started dropping money out of airplanes.” Aid has increased, subsidized(补贴的) loans have become available, and “the universities have gotten the money.”Economist Bryan Caplan, who is writing a book abut education, agrees: “It’s a giant waste of resources that will continue as long as the subsidies continue.”F) Promotional literature for colleges and student loans often speaks of debt as an “investment inyourself.” But an investment is supposed to generate income to pay off the loans. More thanhalf of all recent graduates are unemployed or in jobs that do not require a degree, and the amount of student-loan debt carried by households had increased more than five times since 1999. these graduates were told that a diploma was all they needed to succeed, but it won’t even get them out of the spare bedroom at Mom and Dad’s. for many, the most visible result of their four years is the loan payments, which now average hundreds of dollars a month on lan balances in the tens of thousands.G) It’s true about the money---sort of. College graduates now make 80 percent more than peoplewho have only a high-school diploma, and though there are no precise estimates, the wage premium(高出的部分) for an outstanding school seems to be even higher. But tha t’s not true of every student. It’s very easy to spend four years majoring in English literature and come out no more employable than you were before you went in. conversely, chemical engineers straight out of school can easily make almost four times the wages of an entry-level high-school graduate.H) James Heckman, the Nobel Prize winning economist, has examined how the returns oneducation break down for individuals with different backgrounds and levels of ability. “Even with these high prices, you’re still finding a high return for individuals who are bright and motivated,: he says. On the other hand, “if you’re not college ready, then the answer is no, it’s not worth it.” Experts tend to agree that for the average student, college is still worth it today, but they also agree that the rapid increase in price is eating up more and more of the potential return. For borderline students, tuition(学费) rise can push those returns into negative territory.I) Everyone seems to agree that the government, and parents, should be rethinking how we investin higher education---and that employers need to rethink the increasing use of college degrees as crude screening tools for jobs that don’t really require college skills. “Employers seeing a surplus of college graduates and looking to fill jobs are just adding that requirement,”says Vedder. “In fact, a college degree becomes a job requirement for becoming a bar-tender.”J) We have started to see some change on the finance side. A law passed in 2007 allows many students to cap their loan payment at 10 percent of their income and forgives any balance after25 years. But of course, that doesn’t control the cost of education; it just shifts it to taxpayers.It also encourages graduated to choose lower-paying careers, which reduces the financial return to education still further. “You’re subsidizing people to become priests and poets and so forth,” says Heckman. “You may think that’s a good thing, or you may not.” Either way it will be expensive for the government.K) What might be a lot cheaper is putting more kids to work Caplan notes that work also builds valuable skills---probably more valuable for kids who don’t naturally love sitting in a classroom. Heckman agrees wholeheartedly: “People are different, and those abilities can be shaped. Tha t’s what we’ve learned, and public policy should recognize that.”L) Heckman would like to see more apprenticeship-style(学徒式) programs, where kids can learn in the workplace---learn not just specific job skills, but the kind of “soft skills,” like getting to work on time and getting along with a team, that are crucial for career success. “It’s about having mentors(指导者) and having workplace-based education,”he says. “Time and again I’ve seen examples of this kind of program working.”M) Ah, but how do we get there from here? With better public policy, hopefully, but also by making better individual decision. “Historically markets have been able to handle these things,”says Vedder, “and I think eventually markets will handle this one. If it doesn’timprove soon, people are going to wake up and ask, ‘Why am I going to college?’”46. Caplan suggests that kids who don’t love school go to work.47. An increasing number of families spend more money on houses in a good school district.48. Subsidized loans to college students are a huge waste of money, according to one economist.49. More and more kids find they fare worse with a college diploma.50. For those who are not prepared for higher education, going to college is not worth it.51. Over the years the cost of a college education has increased almost by 100%.52. A law passed recently allows many students to pay no more than one tenth of their income fortheir college loans.53. Middle class Americans have highly valued a good education.54. More kids should be encouraged to participate in programs where they can learn not only jobskills but also social skills.55. Over fifty percent of recent college graduates remain unemployed or unable to find a suitablejob.Section CPassage OneQuestions 56 to 60 are based on the following passage.A recent global survey of 2,000 high-net-worth individuals found that 60% were not planning on a traditional retirement. Among U.S. participants, 75% expected to continue working in some capacity even after stepping away from full-time jobs. “Many of these people made their wealthy by doing something they’re passionate(有激情的) about,” says Daniel Egan, head of behavioral finance for Barclays Wealth Americas. “Given the choice, they prefer to continue working.”Barclays calls these people “nevertirees.”Unlike many Americans compelled into early retirement by company restrictions, the average nevertiree often has no one forcing his hand. If 106-year-old investor Irving Kahn, head of his won family firm, wants to keep coming to work every day, who’s going to stop him? Seventy-eight-year-old Supreme Court Justice Ruth Bader Ginsburg’s job security is guaranteed in the Constitution.It may seem that these elderly people are trying to cheat death. In fact, they are. And it’s working. Howard Friedman, a professor at UC Riverside, found in his research that those who work hardest and are successful in their careers often live the longest lives. “People are generally being given bad advice to slow down, take it easy, stop worrying, are retire to Foloida,”he described one study one study participant, still working at the age of 100, who was recently disappointed to see his son retire.“We’re beginning to see a change in how people view retirement,”says George Leeson, co-director of the Institute of Population Ageing at Oxford. Where once retirement was seen as a brief reward after a long struggle through some miserable job, it is now akin(近似) to being cast aside. What Leeson terms “the Warren Buffett effect”is becoming more broadly appealing as individuals come to “view retirement as not simply being linked to economic productivity but also about contribution.”Observers are split on whether this is a wholly good thing. On the one hand, companies and financial firms can benefit from the wisdom of a resilient(坚韧的) chief. On the other, the new generation can find it more difficult to advance---an argument that typically holds little sway to anevertiree.56. What do we learn about the so-called “nevertiree”?A. they are passionate about making a fortuneB. they have no choice but to continue workingC. they love what they do and choose not to retireD. they will not retire unless they are compelled to57. What do Irving Kahn and Ruth Bader Ginsburg have in common?A. neither of them is subject to forced retirementB. neither of them desires reward for their workC. both cling to their positions despite oppositionD. both are capable of coping with heavy workloads58. What is the finding of Howard Friedman’s research?A. the harder you work, the bigger your fortune will beB. the earlier you retire, the healthier you will beC. elderly people have to slow down to live longerD. working at an advanced age lengthens people’s life59. What is the traditional view of retirement according to the passage?A. it means a burden to the younger generationB. it is a symbol of mature and civilized societyC. it a compensation for one’s life-long hard workD. it helps increase a nation’s economics productivity60. What do critics say about “nevertirees?A. they are an obstacle to a company’s developmentB. they lack the creativity of the younger generationC. they cannot works as efficiently as they used toD. they prevent young people from getting aheadPassage TwoQuestions 61 to 65 are based on the following passage.When we talk about Americans barely into adulthood who are saddled with unbearable levels of debt. The conversation is almost always about student loan debt. but there’s a growing body of evidence suggesting that today’s young adults are also drowning in credit-care debt---and that many of them will take this debt to their graves.More than 20% overspent their income by more than $100 every single month. Since they haven’t built up their credit histories yet, it’s a safe bet that these young adults are paying relatively high interest rates on the resulting credit card debt.Although many young people blame “socializing”as a barrier to saving money, most of them aren’t knocking back $20 drinks in trendy(时尚的) lounges. They’re struggling with much more daily financial demands.To a disturbingly large extent, the young and the broke are relying on credit cards to make it until their next payday. This obviously isn’t sustainable in the long run, and it’s going to put a huge drag on their spending power even after they reach their peak earning years. Because they’ll still be paying interest on that bottle of orange juice or box of spaghetti（意式面条）they bought a decade earlier.A new study out of Ohio State University found that young adults are accumulating creditcard debt at a more rapid rate than other age groups, and that they’re slower at paying it off. “If what we found continues to hold true, we may have more elderly people with substantial financial problems in the future,” warns Lucia Dunn, professor of economics at Ohio State. “If our findings persist, we may be faced with a financial crisis among elderly people who can’t pay off their credit cards.”Dunn says a lot of these young people are never going to get out from under their credit card debt. “Many people are borrow on credit cards so heavily that payoff rates at these levels are not sufficient to recover their credit card debt by the end of their life, which could have loss implications for the credit card issuing banks.”61. What is the main idea of the first paragraph?A. many young Americans will never be able to pay off their debtsB. credit cards play an increasingly important role in college lifeC. credit cards are doing more harm than student loansD. the American credit card system is under criticism62. Why do young people have to pay a higher interest on their credit card debt?A. they tend to forget about the deadlinesB. they haven’t developed a credit historyC. they are often unable to pay back in timeD. they are inexperienced in managing money63. What is said to be the consequence of young adults relying on credit cards to make ends meet?A. it will place an unnecessary burden on societyB. it will give them no motivation to work hardC. it will exert psychological pressure on themD. it will affect their future spending power64. What will happen to young adults if their credit card debt keeps accumulating according to Lucia Dunn?A. they will have to pay an increasingly higher interest rateB. they may experience a financial crisis in their old ageC. their quality of life will be affectedD. their credit cards may be cancelled65. What does Lucia Dunn think might be a risk for the credit card issuing banks?A. they go bankrupt as a result of over-lendingB. they lose large numbers of their regular clientsC. their clients leave their debts unpaid upon deathD. their interest rates have to be reduced now and thenPart IV Translation （30 minutes）Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

2013年12月大学英语六级考试真题(一)答案详解Part 4 Translation参考译文与难点注释The Chinese garden has become a landscape of unique style after an evolution for more than 3 000 years. It includes not only the large gardens built as entertainment venues for the royal family, but also the private gardens built as secluded retreats for scholars, merchants and retired government officials. These gardens have constituted a miniature designed to express the harmonious relationship between man and nature. A typical Chinese garden is surrounded by walls, and in the garden there are ponds, rockwork, trees, flowers and all kinds of buildings linked by winding trails and corridors. Wandering in the gardens, people may feel that a series of well-designed scenery spreads out before us like a landscape scroll.1. 第一句中，"三千多年演变"可以译成an evolution for more than 3 000 years,不能译成more than 3 000 years of evolution;"独具一格的"可以用单个形容词unique来表达，也可以用短语of unique style来表达。

接着，借助谚语内容（将生命花在比生命更长远的事上，就是尽用生命），谚语与题目相结合，可提炼出主题：怎样使生命更有意义。

然后，弄清题目与谚语的关系：主题与例证关系勒最后，确定行文思路：引出话题+提出观点+举例论证+总结建议；总结时，注意要观点明确，贴合所给主题，切勿模棱两可。

2、写作思路：第一段：以“总一分一总”形式引出话题，解释谚语。

第二段：提出观点，指出自己将怎样做，并举例论证。

第三段：做出呼吁，提出建议，总结全文。

Ho w to Li ve a Meanin gful Li fePeople always say that the greatest use of life is to spend it for something that will outlast it. On the one hand, life is spent on something for the future, or for our offspring. For example, people work to build the Three Gorges Dam to make electricity. On the other hand, doing some little but meaningful things can also show the greatest useof life, such as offering a seat to a woman with a child.I will do the following things to make my life meaningful. First, I will plant trees every year to contribute my effort to make the sky blue and the water clean. Second, I will learn my major biology well to cure some diseases, such as cancers. Third, as the saying goes, to do your own job is to contribute your effort to the society.Only by spending our life for something that will outlast it can we contribute to our society. For one thing, we should learn from Lei Feng who did little but meaningful things. For another, we can do whatever we can to protect the environment. In a word, we can make our life meaningful by doing meaningful things.PartⅡListening Comprehension1.听力原文：W: Has my order arrived yet?

第Ⅰ卷阅读题甲必考题一、现代文阅读（9分，每小题3分）阅读下面的文字，完成1～3题老子其人其书的时代，自司马迁《史记》以来即有异说，清代学者崇尚考据，对此议论纷纷，如汪中作《老子考异》，力主老子为战国时人，益启争端。

钱穆先生说：‚老子伪迹不彰，真相大白，则先秦诸子学术思想之系统条贯始终不明，其源流派别终无可言.‛大家都期待这个问题有新的解决线索.过去对于古书真伪及年代的讨论，只能以材料证明纸上材料，没有其它的衡量标准，因而难有定论。

用来印证《老子》的古书，大多收到辨伪家的怀疑，年代确不可移的，恐怕要数到《林非子》。

《吕氏春秋》和《淮南子》，但这几木书戍书太晚，没有多少作用.近年战国秦汉简帛侠籍大黄出上，为学术界提供了许多前所未见的地下材料，这使我们有可能重新考虑《老子》的时代问题。

1973牛长沙马王堆三号汉基出土的串书，内有《老子》两种版本，甲本字体比较早，不避汉高祖讳，应抄写于高祖即帝位前，乙本避高祖讳，可以抄写于文帝初。

这两本《老子》抄写年代都晚，无益于《老子》著作年代的推定，但乙本前面有《黄帝书》四篇，系黄‛、‚老‛合抄之本，则从根本上改变了学术界对早期道家的认识。

郭沐若先生曾指出，道家都是以‚发明黄老道德意‛为其指归，故也可称之为黄老学派.《老子》和《黄帝书》是道家的经典，在汉初被妙写在《老子》前面的《黄帝书》显然在当时公众心目中已据有崇高位臵，不会是刚刚撰就的作品。

同时，《黄帝书》与《申子》、《慎子》、《韩非子》等有许多共通文句，而申不害、慎到、韩非二人均曾学黄老之术，这些共通之处可认作对《皇帝书》的引用阐发。

一、作文【作文(一)】The Impact of the Mobile Phone in People’s LifeThe thought-provoking drawing mirrors a common phenomenon in contemporary society that there is the negative influence of mobile phone. As is subtly shown in the picture，so many people are too much addicted to cell phones that they use walking sticks to see the road. What a meaningful cartoon!It is to me that indulging in mobile phones produces native influences on body and mind. First and foremost, overusing mobile phones is detrimental to physical health for watching mobiles for a long stretch definitely impairs one’s eyesight. Suppose that a man is addicted in cell phones in whatever situation, it will be very disadvantageous for him to concentrate on his work, learning, or daily life and is very likely to hurt him. Furthermore, overusing cell phones adversely affects state of mind. An addict may stay inside his bubble instead of pursuing other endeavors, which eventually prevents the growth of think skills.It is high time that we took effective measures to curb this trend. I cherish a belief that cell phones themselves are not good or bad and we can benefit a lot from it as long as we take a good control over them.【作文(二)】The Impact of the Internet on the Way People Communicate网络对人们沟通产生的影响Internet does exert such a profound effect on our life that it revolutionizes the way of people’s living and thinking. As is subtly revealed in the portrayal，there are two parents sitting in the front of computer，who are chatting with their child on the internet. What a meaningful picture!From my perspective, the electronic contact cannot replace face to face communication owing to the following factors. To begin with, over-reliance on electronic contact will damage the interpersonal relationship, for the cold machine never replaces a warm-hearted greeting face to face. For example, the aged parents would like their only son who works far away home to come back home more often rather than to talk with him on th e internet occasionally. What’s more, face to face communication is preferable because it is beneficial to build a harmonious society, for it attaches more importance on human affection and feelings instead of convenience and speed.Hence, it is necessary for us to use Internet in a reasonable way. After all, Internet is invented to connect you and me, and to bring conveniences to our life rather than set a barrier to keep people beyond reach. If we want to keep our interpersonal relationship more effectively, weshould spend more time with them face to face in real life. Only in this way can we not only make full use of the communication tool on the net but also make our relationship tighter.二、听力测试（原文）2013年12月大学英语四级听力真题原文：听力短对话Question 1M: After high school, I’d like to go to college and major in business administration.W: But I’d rather spend my college days finding out how children learn.Q: What do we learn from the conversation?Question 2W: Is everything ready for the conference?M: The only thing left to do is set up the microphones and speakers.

It's a wonderful little museum.M: Oh good. Now what about Amitsville? I have some friends. I'd like to visit there and I also want to get to Newton. They are near each other, aren't they?W: Hmm... well, they are actually in opposite directions. Amitsville is northeast. It's about thirty five miles northeast of here.M: Huh-uh, thirty five miles northeast. And how about Newton?W: Well, Newton is in the other direction. It's southwest, so it isn't really very close to Amitsville at all and it's a long drive. It's about fifty five miles southwest from here and the road is not at all straight.M: Fifty five miles southwest! Well, maybe I won't go there this time.W: I'd recommend visiting Westfield or Great Town. They are both very close. Westfield is just seven miles west of here and Great Town is about five miles south. They are really pretty little towns with lots of old houses and beautiful tree-lined streets.M: I see. Seven miles west to Westfield and five miles south to Great Town. Good. Well, I think that's all the information I need for a while. Thank you. You've been very helpful.W: You're welcome, sir.

What's the program for the rest of that day?W: It's quite full, I'm afraid. At eleven, you're seeing Jeana Rivard at Meg Star and then you'll have a lunch engagement with Gaven from the Chamber of Commerce at one.M: Where's that?W: You're meeting him at his office and then he's taking you somewhere.M: Good, that sounds fine.

She joined the Peace Corps after she graduated from the college because she wanted to do something to help other people. She had been brought up on a farm, so the Peace Corps assigned her to a agricultural project. Before she went to Brazil, she studied Portuguese for three months. She also learnt a great deal about its history and culture. During her two years with the Peace Corps, Donna lived in a village in northeast Brazil. That part of Brazil is very dry and farming is often difficult there. Donna helped the people of the village to organise an arrigation project, and she also advised themon planting corps. They didn’t require much water. When Donna returned to the States, shecould n’t settle down. She tried several jobs, but they seemed very boring to her. She couldn’t get Brazil out of her mind. Finally, one day she got on an plane and went back to Brazil. She wasn’t sure what she’s going to do. She just wanted to be there. After a few weeks, Donna found a job as an English teacher, teaching five classes a day. Like most of the teachers, she doesn’t make much money. She shares a small apartment with another teacher. And she makes a little extra money by sending stories to newspapers in the States. Eventually she wants to quit teaching and work as a full-time journalist.Question 16Why did Donna join the Peace Corps after she graduated from college?Question 17What was Donna assigned to do in Brazil?Question 18Why did Donna go back to Brazil once again?Question 19How did Donna make extra money to support herself?Listening Passage 2Results of a recent Harry’s pool on free time showed that the average work week for many Americans is 50 hours. With the time spent eating, sleeping and taking care of the household duties, there’s little time left for leisure activities for many Americans. However, having free time to relax and pursue hobbies is important. People need time away from the pressures of study or work to relax and enjoy time with friends and family. In many countries free time is spent in different ways. The results of a Harry’s pool showed that reading was the most popular spare time activity in the US. This was followed by watching TV. In a UK survey on leisure time activities, watching TV and videos was the most popular. Listening to the radio came second. In a similar survey conducted in Japan, the most popular free time activity was eating out. The second most popular activity was driving. There were also differences in the most popular outdoor pursuits between the three countries. The most popular outdoor activity for Americans was gardening. In the UK, it was going to the pub. In Japan, going to bars ranked eighth in popularity and gardening ranked ninth. Although people around the world may enjoy doing similar things in their free time, there’s evidence to suggest that these interests are changing. In the US, for example, the popularity of computer activities is increasing. Many more people in the States are spending their free time surfing the web, emailing friends or playing games online.Question 20What is the recent Harry Pole about?Question 21What was the most popular leisure activity in the US?Question 22What was the most popular outdoor pursuit in the UK?Listening Passage 3On March 13th, while on duty Charles Mclaughlin, a very careless driver employed by the company Lummis was involved in another accident. The accident occurred in Riverside California. Not paying attention to his driving, Mclaughlin turned right on main street and 33rd street and hit Volkswagen rabbit. This caused minor damage to his truck and serious damage to the car. On the basis of the police report, the Lummis accident committee correctly determined that Mclaughlin had been quite careless. As a result of the committee’s conclusion, the branch manager Mr. David Rossi reported that he had talked with Mclaughlin about his extremely poor driving record. Further evidence of Mclaughlin's irresponsibility occurred on May 6th when he was returning from his shift. That day he ran into a roll-up door at the Lummis facility in Valero, causing significant damage to the door. Damage to the truck, however, was minor. Finally, on June 7th, Mclaughlin once again demonstrated his carelessness by knocking down several mail boxes near the edge of the company’s pa rking lot. There was damage to the mailboxes and minor damage to the truck. Mr. David Rossi stated that he had spoken with Mclaughlin on several occasions about his driving record. He added that he had warned Mclaughlin that three preventable accidents in one year could lead to his discharge, as indeed it should.23. What did the Lummis accident committee find out about the accident that occurred on March 13th?24. What did Mclaughlin do on June 7th near the edge of the company’s parking lot?25. What is most probably going to happen to Mclaughlin?【听力填空】：When Captain Cook asked the chiefs in Tahiti why they always ate apart and alone, they replied, “Because it is right.” If we ask Americans why they eat with knives and forks, or why their men wear pants instead of skirts or why they may be married to only one person at a time, we are likely to get similar and very uninformative answers because it’s right, because that’s the way it’s done, because it’s the custom or even I don’t know. The reason for these and countless other patterns of social behavior is that they are controlled by social norms shared rules or guide lines which prescribe the behavior that is appropriate in a given situation. Norms define how people ought to behave under particular circumstances in a particular society. We conform to norms so readily that we are hardly aware they exist. In fact we are much more likely to notice departures from norms than conformity to them. You will not be surprised if a stranger tried to shake handswhen you were introduced, but you might be a little startled if they bowed, started to stroke you or kissed you on both cheeks. Yet each of these other forms of greeting is appropriate in other partsof the world. When we visit another society whose norms are different, we quickly become aware that things we do this way, they do that way.【四级长对话】9. B) It has an interesting museum.10.

Section BDirections: 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.The Gatais used to frown when they received power bills that routinely topped $200. Last September the couple moved into a 1,500-square-foot home in Premier Gardens, a subdivision of 95 "zero-energy homes"(ZEH)just outside town. Now they're actually eager to see their electricity bills. The grand total over the 10 months they've lived in the three-bedroom house: $ 75. For the past two months they haven't paid a cent.ZEH communities are the leading edge of technologies that might someday create houses that produce as much energy as they consume. Premier Gardens is one of a half-dozen subdivisions in California where every home cuts power consumption by 50% , mostly by using low-power appliances and solar panels.Aside from the panels on the roof, Premier Gardens looks like a community of conventional homes. But inside, special windows cut power bills by blocking solar heat in summer and retaining indoor warmth in winter.The rest of the energy savings comes from the solar units. They don't just feed the home they serve. If they generate more power than the home is using, the excess flows into the utility's power grid(电网). The residents are billed by "net metering" : they pay for the amount of power they tap off the grid, less the kilowatts(千瓦)they feed into it. If a home generates more power than it uses, the bill is zero.That sounds like a bad deal for the power company, but it's not. Solar homes produce the most power on the hot sunny afternoons when everyone rushes home to turn up the air conditioner. " It helps us lower usage at peak power times," says solar expert Mike Keesee. " That lets us avoid building costly plants or buying expensive power at peak usage time. "What's not to like? Mostly the costs. The special features can add $ 25,000 or more to the purchase price of a house. Tax breaks bring the cost down, especially in California, but in many states ZEHs can be prohibitively expensive.

So says psychologist Maureen O'Sullivan from the University of San Francisco. She suggests that humans have always tried to strengthen the pair-bond to maximise(使最大化)reproductive success.Many societies throughout history and around the world today have cultivated strong pressures to stay married. In those where ties to family and community are strong, lifelong marriages can be promoted by practices such as the cultural prohibition of divorce and arranged marriages that are seen as a contract between two families, not just two individuals. In modern western societies, however, the focus on individuality and independence means that people are less concerned about conforming to(遵守)the dictates of family and culture. In the absence of societal pressures to maintain pair-bonds, O'Sullivan suggests that romantic love has increasingly come to be seen as the factor that should determine who we stay with and for how long. " That's why historically we see an increase in romantic love as a basis for forming long-term relationships," she says.According to O'Sullivan culture also shapes the sorts of feelings we expect to have, and actually do experience, when in love. Although the negative emotions associated with romantic love—fear of loss, disappointment and jealousy—are fairly consistent across cultures, the positive feelings can vary. " If you ask Japanese students to list the positive attributes they expect in a romantic partner, they rate highly things like loyalty, commitment and devotion," says O'Sullivan. " If you ask American college women, they expect everything under the sun: in addition to being committed, partners have to be amusing, funny and a friend. "We judge a potential partner according to our specific cultural expectations about what romantic love should feel like. If you believe that you have found true romance, and your culture tells you that this is what a long-term relationship should be based on, there is less need to rely on social or family pressures to keep couples together, O'Sullivan argues.63．What does the author say about people's views of an ideal romantic relationship?A．They vary from culture to culture.B．They ensure the reproductive success.C．They reflect the evolutionary process.D．They are influenced by psychologists.64．We can infer from the passage that strong family and community ties______.A．largely rely on marriage contractsB．can contribute to stable marriagesC．often run counter to romantic loveD．make divorces virtually unacceptable65．Without social pressures to keep pair-bonds, romantic love______.A．will be a substitute for marriage in human relationshipsB．plays a key role in maintaining long-term relationshipsC．is likely to replace the dictates of family and societyD．is a way to develop individuality and independence66．O'Sullivan believes that when people from different cultures fall in love, ______. A．they expect different things from their partnerB．they tend to exaggerate each other's positive qualitiesC．they often fail to see each other's negative qualitiesD．they lay more emphasis on commitment and devotion67．We can conclude from the passage that______.A．cultural differences often tear apart a family built on romantic loveB．marriages are hard to sustain without social or family pressuresC．romantic love is becoming increasingly important in family relationshipsD．romantic love tends to yield where family or social pressures are strongPassage OneQuestions 56 to 60 are based on the following passage.In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us.Studies have shown, for instance, that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual cues, like plate size and lighting, have been shown to affect portion size and consumption.A new study suggested that our short-term memory also may play a role in appetite. Several hours after a meal, people’s hunger levels were predictednot by how much they’d eaten but rather by how much food they’d seen in front of them—in other words, how much they remembered eating.This disparity (差异) suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal, says Jeffrey M. Brunstrom, a professor of experimental psychology at the University of Bristol.“Hunger isn’t controlled solely by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal,” Brunstrom says. “This shows that the relationship between hunger and food intake is more complex than we thought.”These findings echo earlier research that suggests our perception of food can sometimes trick our body’s response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie (卡路里) milkshake on two separate occasions produced different levels of hunger-related hormones (荷尔蒙), depending on whether the shake’s label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they’d consumed a higher-calorie shake.What does this mean for our eating habits? Although it hardly seems practical to trick ourselves into eating less, the new findings do highlight the benefits of focusing on our food and avoiding TV and multitasking while eating.The so-called mindful-eating strategies can fight distractions and help us control our appetite, Brunstrom says.注意：此部分试题请在答题卡2上作答。
