The function of a university is to guide students to a better understanding of themselves and the world.写作答案:Part 1:Directions: Write an essay of 200 words based on the following chart.参考范文:The chart illustrates the consumption of different types of beverages in a typical western country over a span of 30 years, from 1980 to 2010. It is clear that the consumption of fruit juice and bottled water increased significantly, while the consumption of carbonated drinks declined.In 1980, carbonated drinks were the most popular, with over 250 liters consumed per person per year. Fruit juice and bottled water were consumed at a much lower rate, with approximately 50 liters and 10 liters per person respectively.However, by 2010, the situation had changed dramatically. The consumption of carbonated drinks had dropped to around 100 liters per person annually, less than half of what it was in 1980. On the other hand, the consumption of fruit juice and bottled water soared to 200 liters and 80 liters respectively.There are several factors contributing to this trend. Firstly, people are becoming more health-conscious, and are opting for healthier alternatives to carbonated drinks. Secondly, the convenience of bottled water has made it a popular choice, particularly among young people. Lastly, the marketing of fruit juice as a natural and nutritious choice has increased its popularity.In conclusion, the chart highlights the change in beverage consumption patterns over the past 30 years. Carbonated drinks have been largely replaced by fruit juice and bottled water, reflecting a growing trend towards healthier choices.Part 2:Directions: Write an essay of 600 words on the following topic.参考范文:The Impact of Social Media on YouthIntroduction:In today's digital age, social media plays an influential role in the lives of young people. This essay will explore the impact of social media on youth, focusing on its positive and negative effects.Positive effects:Firstly, social media platforms allow young people to connect and communicate with others from different cultures and countries, fostering a sense of global understanding and unity. This broadens their perspectives and promotes cultural exchange.Secondly, social media provides a platform for young individuals to express themselves creatively through sharing photos, videos, and artwork. This can boost their self-esteem and confidence by gaining recognition and feedback from others.Lastly, social media offers educational opportunities, as many organizations and institutions use these platforms to share knowledge and provide online courses. This enables youth to access educational resources and expand their knowledge beyond traditional classrooms.Negative effects:On the other hand, the excessive use of social media can have detrimental effects on mental health and well-being. Young people may become addicted to social media, increasing the risk of anxiety, depression,and social isolation. The constant comparison to others' highlight reels can lead to feelings of inadequacy and low self-worth.Furthermore, cyberbullying is prevalent on social media, with young people being vulnerable to online harassment and bullying. This can have severe consequences on their mental and emotional well-being, and even lead to self-harm or suicidal thoughts.Lastly, the overexposure to curated images and idealized lifestyles on social media can distort young people's perception of reality, leading to body image issues and unhealthy behaviors like disordered eating or excessive dieting.Conclusion:In conclusion, social media has both positive and negative impacts on young people. It provides opportunities for global connections, creative expression, and online education. However, its excessive use can negatively affect mental health, contribute to cyberbullying, and distort perception of reality. It is crucial for young people to use social media in moderation, be aware of its potential risks, and seek support when needed. Additionally, parents, educators, and policymakers should work together to ensure responsible use of social media and provide necessary resources for young people to navigate the digital world effectively.。

That whispered message, half invitation and half forcing, is what most of us think of when we hear the words peer pressure. It usually leads to no good-drinking, drugs and casual sex. But in her new book Join the Club, Tina Rosenberg contends that peer pressure can also be a positive force through what she calls the social cure, in which organizations and officials use the power of group dynamics to help individuals improve their lives and possibly the word.Rosenberg, the recipient of a Pulitzer Prize, offers a host of example of the social cure in action: In South Carolina, a state-sponsored antismoking program called Rage Against the Haze sets out to make cigarettes uncool. In South Africa, an HIV-prevention initiative known as LoveLife recruits young people to promote safe sex among their peers.The idea seems promising,and Rosenberg is a perceptive observer. Her critique of the lameness of many pubic-health campaigns is spot-on: they fail to mobilize peer pressure for healthy habits, and they demonstrate a seriously flawed understanding of psychology.”Dare to be different, please don’t smoke!”pleads one billboard campaign aimed at reducing smoking among teenagers-teenagers, who desire nothing more than fitting in. Rosenberg argues convincingly that public-health advocates ought to take a page from advertisers, so skilled at applying peer pressure. But on the general effectiveness of the social cure, Rosenberg is less persuasive. Join the Club is filled with too much irrelevant detail and not enough exploration of the social and biological factors that make peer pressure so powerful. The most glaring flaw of the social cure as it’s presented here is that it doesn’t work very well for very long. Rage Against the Haze failed once state funding was cut. Evidence that the LoveLife program produces lasting changes is limited and mixed.There’s no doubt that our peer groups exert enormous influence on our behavior. An emerging body of research shows that positive health habits-as well as negative ones-spread through networks of friends via social communication. This is a subtle form of peer pressure: we unconsciously imitate the behavior we see every day.Far less certain, however, is how successfully experts and bureaucrats can select our peer groups and steer their activities in virtuous directions. It’s like the teacher who breaks up the troublemakers in the back row by pairing them with better-behaved classmates. The tactic never really works. And that’s the problem with a social cure engineered from the outside: in the real world, as in school, we insist on choosing our own friends.21. According to the first paragraph, peer pressure often emerges as[A] a supplement to the social cure[B] a stimulus to group dynamics[C] an obstacle to school progress[D] a cause of undesirable behaviors22. Rosenberg holds that public advocates should[A] recruit professional advertisers[B] learn from advertisers’experience[C] stay away from commercial advertisers[D] recognize the limitations of advertisements23. In the author’s view, Rosenberg’s book fails to[A] adequately probe social and biological factors[B] effectively evade the flaws of the social cure[C] illustrate the functions of state funding[D]produce a long-lasting social effect24. Paragraph 5shows that our imitation of behaviors[A] is harmful to our networks of friends[B] will mislead behavioral studies[C] occurs without our realizing it[D] can produce negative health habits25. The author suggests in the last paragraph that the effect of peer pressure is[A] harmful[B] desirable[C] profound[D] questionableA deal is a deal-except, apparently ,when Entergy is involved. The company, a major energy supplier in New England, provoked justified outrage in Vermont last week when it announced it was reneging on a longstanding commitment to abide by the strict nuclear regulations. Instead, the company has done precisely what it had long promised it would not challenge the constitutionality of Vermont’s rules in the federal court, as part of a desperate effort to keep its Vermont Yankee nuclear power plant running. It’s a stunning move.The conflict has been surfacing since 2002, when the corporation bought V ermont’s only nuclear power plant, an aging reactor in Vernon. As a condition of receiving state approval for the sale, the company agreed to seek permission from state regulators to operate past 2012. In 2006, the state went a step further, requiring that any extension of the plant’s license be subject to Vermont legislature’s approval. Then, too, the company went along.Either Entergy never really intended to live by those commitments, or it simply didn’t foresee what would happen next. A string of accidents, including the partial collapse of a cooling tower in 207 and the discovery of an underground pipe system leakage, raised serious questions about both Vermont Yankee’s safety and Entergy’s management–especially after the company made misleading statements about the pipe. Enraged by Entergy’s behavior, the Vermont Senate voted 26 to 4 last year against allowing an extension.Now the company is suddenly claiming that the 2002 agreement is invalid because of the 2006 legislation, and that only the federal government has regulatory power over nuclear issues. The legal issues in the case are obscure: whereas the Supreme Court has ruled that states do have some regulatory authority over nuclear power, legal scholars say that Vermont case will offer a precedent-setting test of how far those powers extend. Certainly, there are valid concerns about the patchwork regulations that could result if every state sets its own rules. But had Entergy kept its word, that debate would be beside the point.The company seems to have concluded that its reputation in Vermont is already so damaged that it has noting left to lose by going to war with the state. But there should be consequences.Permission to run a nuclear plant is a poblic trust. Entergy runs 11 other reactors in the United States, including Pilgrim Nuclear station in Plymouth. Pledging to run Pilgrim safely, the company has applied for federal permission to keep it open for another 20 years. But as the Nuclear Regulatory Commission (NRC) reviews the company’s application, it should keep it mind what promises from Entergy are worth.26. The phrase “reneging on”(Line 3.para.1) is closest in meaning to[A] condemning.[B] reaffirming.[C] dishonoring.[D] securing.27. By entering into the 2002 agreement, Entergy intended to[A] obtain protection from V ermont regulators.[B] seek favor from the federal legislature.[C] acquire an extension of its business license .[D] get permission to purchase a power plant.28. According to Paragraph 4, Entergy seems to have problems with its[A] managerial practices. [B] technical innovativeness.[C] financial goals. [D] business vision29. In the author’s view, the Vermont case will test[A] Entergy’s capacity to fulfill all its promises.[B] the mature of states’patchwork regulations.[C] the federal authority over nuclear issues .[D] the limits of states’power over nuclear issues.30. It can be inferred from the last paragraph that[A] Entergy’s business elsewhere might be affected.[B] the authority of the NRC will be defied.[C] Entergy will withdraw its Plymouth application.[D] Vermont’s reputation might be damaged.In the idealized version of how science is done, facts about the world are waiting to be observed and collected by objective researchers who use the scientific method to carry out their work. But in the everyday practice of science, discovery frequently follows an ambiguous and complicated route. We aim to be objective, but we cannot escape the context of our unique life experience. Prior knowledge and interest influence what we experience, what we think our experiences mean, and the subsequent actions we take. Opportunities for misinterpretation, error, and self-deception abound.Consequently, discovery claims should be thought of as protoscience. Similar to newly staked mining claims, they are full of potential. But it takes collective scrutiny and acceptance to transform a discovery claim into a mature discovery. This is the credibility process, through which the individual researcher’s me, here, now becomes the community’s anyone, anywhere, anytime. Objective knowledge is the goal, not the starting point.Once a discovery claim becomes public, the discoverer receives intellectual credit. But, unlike with mining claims, the community takes control of what happens next. Within the complex social structure of the scientific community, researchers make discoveries; editors and reviewers act as gatekeepers by controlling the publication process; other scientists use the new finding to suit their own purposes; and finally, the public (including other scientists) receives the new discovery and possibly accompanying technology. As a discovery claim works it through the community, the interaction and confrontation between shared and competing beliefs about the science and the technology involved transforms an individual’s discovery claim into the community’s credible discovery.Two paradoxes exist throughout this credibility process. First, scientific work tends to focus on some aspect of prevailing Knowledge that is viewed as incomplete or incorrect. Little reward accompanies duplication and confirmation of what is already known and believed. The goal is new-search, not re-search. Not surprisingly, newly published discovery claims and credible discoveries that appear to be important and convincing will always be open to challenge and potential modification or refutation by future researchers. Second, novelty itself frequently provokes disbelief. Nobel Laureate and physiologist Albert Azent-Gyorgyi once described discovery as “seeing what everybody has seen and thinking what nobody has thought.”But thinking what nobody else has thought and telling others what they have missed may not change their views. Sometimes years are required for truly novel discovery claims to be accepted and appreciated.In the end, credibility “happens”to a discovery claim –a process that corresponds to what philosopher Annette Baier has described as the commons of the mind. “We reason together, challenge, revise, and complete each other’s reasoning and each other’s conceptions of reason.”31. According to the first paragraph, the process of discovery is characterized by its[A] uncertainty and complexity.[B] misconception and deceptiveness.[C] logicality and objectivity.[D] systematicness and regularity.32. It can be inferred from Paragraph 2 that credibility process requires[A] strict inspection. [B]shared efforts.[C] individual wisdom. [D]persistent innovation.33.Paragraph 3 shows that a discovery claim becomes credible after it[A] has attracted the attention of the general public.[B]has been examined by the scientific community.[C] has received recognition from editors and reviewers.[D]has been frequently quoted by peer scientists.34. Albert Szent-Györgyi would most likely agree that[A] scientific claims will survive challenges.[B]discoveries today inspire future research.[C] efforts to make discoveries are justified.[D]scientific work calls for a critical mind.35.Which of the following would be the best title of the test?[A] Novelty as an Engine of Scientific Development.[B]Collective Scrutiny in Scientific Discovery.[C] Evolution of Credibility in Doing Science.[D]Challenge to Credibility at the Gate to Science.If the trade unionist Jimmy Hoffa were alive today, he would probably represent civil servant. When Hoffa’s Teamsters were in their prime in 1960, only one in ten American government workers belonged to a union; now 36% do. In 2009 the number of unionists in America’s public sector passed that of their fellow members in the private sector. In Britain, more than half of public-sector workers but only about 15% of private-sector ones are unionized.There are three reasons for the public-sector unions’thriving. First, they can shut things down without suffering much in the way of consequences. Second, they are mostly bright and well-educated. A quarter of America’s public-sector workers have a university degree. Third, they now dominate left-of-centre politics. Some of their ties go back a long way. Britain’s Labor Party, as its name implies, has long been associated with trade unionism. Its current leader, Ed Miliband, owes his position to votes from public-sector unions.At the state level their influence can be even more fearsome. Mark Baldassare of the Public Policy Institute of California points out that much of the state’s budget is patrolled by unions. The teachers’unions keep an eye on schools, the CCPOA on prisons and a variety of labor groups on health care.In many rich countries average wages in the state sector are higher than in the private one. But the real gains come in benefits and work practices. Politicians have repeatedly “backloaded”public-sector pay deals, keeping the pay increases modest but adding to holidays and especially pensions that are already generous.Reform has been vigorously opposed, perhaps most egregiously in education, where charter schools, academies and merit pay all faced drawn-out battles. Even though there is plenty of evidence that the quality of the teachers is the most important variable, teachers’unions have fought against getting rid of bad ones and promoting good ones.As the cost to everyone else has become clearer, politicians have begun to clamp down. In Wisconsin the unions have rallied thousands of supporters against Scott Walker, the hardline Republican governor. But many within the public sector suffer under the current system, too. John Donahue at Harvard’s Kennedy School points out that the norms of culture in Western civil services suit those who want to stay put but is bad for high achievers. The only American public-sector workers who earn well above $250,000 a year are university sports coaches and the president of the United States. Bankers’fat pay packets have attracted much criticism, but a public-sector system that does not reward high achievers may be a much bigger problem for America.36. It can be learned from the first paragraph that[A] Teamsters still have a large body of members.[B] Jimmy Hoffa used to work as a civil servant.[C] unions have enlarged their public-sector membership.[D]the government has improved its relationship with unionists.37. Which of the following is true of Paragraph 2?[A] Public-sector unions are prudent in taking actions.[B] Education is required for public-sector union membership.[C] Labor Party has long been fighting against public-sector unions.[D]Public-sector unions seldom get in trouble for their actions.38. It can be learned from Paragraph 4 that the income in the state sector is[A] illegally secured. [B] indirectly augmented.[C] excessively increased. [D]fairly adjusted.39. The example of the unions in Wisconsin shows that unions[A]often run against the current political system.[B]can change people’s political attitudes.[C]may be a barrier to public-sector reforms.[D]are dominant in the government.40. John Donahue’s attitude towards the public-sector system is one of[A]disapproval.[B]appreciation.[C]tolerance.[D]indifference.Think of those fleeting moments when you look out of an aeroplane window and realise that you are flying, higher than a bird. Now think of your laptop, thinner than a brown-paper envelope, or your cellphone in the palm of your hand. Take a moment or two to wonder at those marvels. You are the lucky inheritor of a dream come true.The second half of the 20th century saw a collection of geniuses, warriors, entrepreneurs and visionaries labour to create a fabulous machine that could function as a typewriter and printing press, studio and theatre, paintbrush and gallery, piano and radio, the mail as well as the mail carrier. (41)The networked computer is an amazing device, the first media machine that serves as the mode of production, means of distribution, site of reception, and place of praise and critique. The computer is the 21st century's culture machine.But for all the reasons there are to celebrate the computer, we must also tread with caution. (42)I call it a secret war for two reasons. First, most people do not realise that there are strong commercial agendas at work to keep them in passive consumption mode. Second, the majority of people who use networked computers to upload are not even aware of the significance of what they are doing.All animals download, but only a few upload. Beavers build dams and birds make nests. Yet for the most part, the animal kingdom moves through the world downloading. Humans are unique in their capacity to not only make tools but then turn around and use them to create superfluous material goods - paintings, sculpture and architecture - and superfluous experiences - music, literature, religion and philosophy. (43)For all the possibilities of our new culture machines, most people are still stuck in download mode. Even after the advent of widespread social media, a pyramid of production remains, with a small number of people uploading material, a slightly larger group commenting on or modifying that content, and a huge percentage remaining content to just consume. (44)Television is a one-way tap flowing into our homes. The hardest task that television asks ofanyone is to turn the power off after he has turned it on.(45)What counts as meaningful uploading? My definition revolves around the concept of "stickiness" - creations and experiences to which others adhere.[A] Of course, it is precisely these superfluous things that define human culture and ultimately what it is to be human. Downloading and consuming culture requires great skills, but failing to move beyond downloading is to strip oneself of a defining constituent of humanity.[B] Applications like , which allow users to combine pictures, words and other media in creative ways and then share them, have the potential to add stickiness by amusing, entertaining and enlightening others.[C] Not only did they develop such a device but by the turn of the millennium they had also managed to embed it in a worldwide system accessed by billions of people every day.[D] This is because the networked computer has sparked a secret war between downloading and uploading - between passive consumption and active creation - whose outcome will shape our collective future in ways we can only begin to imagine.[E] The challenge the computer mounts to television thus bears little similarity to one format being replaced by another in the manner of record players being replaced by CD players.[F] One reason for the persistence of this pyramid of production is that for the past half-century, much of the world's media culture has been defined by a single medium - television - and television is defined by downloading.[G]The networked computer offers the first chance in 50 years to reverse the flow, to encourage thoughtful downloading and, even more importantly, meaningful uploading.Part CSince the days of Aristotle, a search for universal principles has characterized the scientific enterprise. In some ways, this quest for commonalities defines science. Newton’s laws of motion and Darwinian evolution each bind a host of different phenomena into a single explicatory frame work.(46)In physics, one approach takes this impulse for unification to its extreme, and seeks a theory of everything—a single generative equation for all we see.It is becoming less clear, however, that such a theory would be a simplification, given the dimensions and universes that it might entail, nonetheless, unification of sorts remains a major goal.This tendency in the natural sciences has long been evident in the social sciences too. (47)Here, Darwinism seems to offer justification for it all humans share common origins it seems reasonable to suppose that cultural diversity could also be traced to more constrained beginnings. Just as the bewildering variety of human courtship rituals might all be considered forms of sexual selection, perhaps the world’s languages, music, social and religious customs and even history are governed by universal features. (48)To filter out what is unique from what is shared might enable us to understand how complex cultural behavior arose and what guides it in evolutionary or cognitive terms.That, at least, is the hope. But a comparative study of linguistic traits published online today supplies a reality check. Russell Gray at the University of Auckland and his colleagues considerthe evolution of grammars in the light of two previous attempts to find universality in language. The most famous of these efforts was initiated by Noam Chomsky, who suggested that humans are born with an innate language—acquisition capacity that dictates a universal grammar. A few generative rules are then sufficient to unfold the entire fundamental structure of a language, which is why children can learn it so quickly.(49)The second, by Joshua Greenberg, takes a more empirical approach to universality identifying traits (particularly in word order) shared by many language which are considered to represent biases that result from cognitive constraintsGray and his colleagues have put them to the test by examining four family trees that between them represent more than 2,000 languages.(50)Chomsky’s grammar should show patterns of language change that are independent of the family tree or the pathway tracked through it. Whereas Greenbergian universality predicts strong co-dependencies between particular types of word-order relations. Neither of these patterns is borne out by the analysis, suggesting that the structures of the languages are lire age-specific and not governed by universalsSection III WritingSome internationals students are coming to your university.

Mark your answers on ANSWER SHEET 1.(40 points)Text 1Homework has never been terribly popular with students and even many parents, but in recent years it has been particularly scorned. School districts across the country, most recently Los Angeles Unified, are revising their thinking on his educational ritual. Unfortunately, L.A. Unified has produced an inflexible policy which mandates that with the exception of some advanced courses, homework may no longer count for more than 10% of a student’s academic grade.This rule is meant to address the difficulty that students from impoverished or chaotic homes might have in completing their homework. But the policy is unclear and contradictory. Certainly, no homework should be assigned that students cannot do without expensive equipment. But if the district is essentially giving a pass to students who do not do their homework because of complicated family lives, it is going riskily close to the implication that standards need to be lowered for poor children.District administrators say that homework will still be a pat of schooling: teachers are allowed to assign as much of it as they want. But with homework counting for no more than 10% of their grades, students can easily skip half their homework and see vey little difference on their report cards. Some students might do well on state tests withoutcompleting their homework, but what about the students who performed well on the tests and did their homework? It is quite possible that the homework helped. Yet rather than empowering teachers to find what works best for their students, the policy imposes a flat, across-the-board rule.At the same time, the policy addresses none of the truly thorny questions about homework.If the district finds homework to be unimportant to its students’ academic achievement, it should move to reduce or eliminate the assignments, not make them count for almost nothing. Conversely, if homework does nothing to ensure that the homework students are not assigning more than they are willing to review and correct.The homework rules should be put on hold while the school board, which is responsible for setting educational policy, looks into the matter and conducts public hearings. It is not too late for L.A. Unified to do homework right.21.It is implied in paragraph 1 that nowadays homework_____.[A] is receiving more criticism[B]is no longer an educational rit ual[C]is not required for advanced courses[D]is gaining more preferences22.L.A.Unified has made the rule about homework mainly because poor students_____.[A]tend to have moderate expectations for their education[B]have asked for a different educational standard[C]may have problems finishing their homewo rk[D]have voiced their complaints about homework23.According to Paragraph 3,one problem with the policy is that it may____.[A]discourage students from doing homewor k[B]result in students' indifference to their report cards[C]undermine the authority of state tests[D]restrict teachers' power in education24. As mentioned in Paragraph 4, a key question unanswered about homework is whether______. [A] it should be eliminat ed[B]it counts much in schooling[C]it places extra burdens on teachers[D]it is important for grades25.A suitable title for this text could be______.[A]Wrong Interpretation of an Educational Polic y[B]A Welcomed Policy for Poor Students[C]Thorny Questions about HomeworkA Faulty Approach to HomeworkText2Pretty in pink: adult women do not rememer being so obsessed with the colour, yet it is pervasive in our young girls’ lives. Tt is not that pink is intrinsically bad, but it is such a tiny slice of the rainbow and, though it may celebrate girlhood in one way, it also repeatedly and firmly fuses girls’ identity to appearance. Then it presents that connection, even among two-year-olds, between girls as not only innocent but as evidence of innocence. Looking around, I despaired at the singular lack of imagination about girl s’ lives and interests.Girls’ attraction to pink may seem unavoidable, somehow encoded in their DNA, but according to Jo Paoletti, an associate professor of American Studies, it is not. Children were not colour-coded at all until the early 20th century: in the era before domestic washing machines all babies wore white as a practical matter, since the only way of getting clothes clean was to boil them. What’s more, both boys and girls wore what were thought of as gender-neutral dresses.When nursery colours were introduced, pink was actually considered the more masculine colour, a pastel version of red, which was associated with strength. Blue, with its intimations of the Virgin Mary, constancy and faithfulness, symbolised femininity. It was not until the mid-1980s, when amplifying age and sex differences became a dominant children’s marketing strategy, that pink fully came into its own,when it began to seem inherently attractive to girls, part of what defined them as female, at least for the first few critical years.I had not realised how profoundly marketing trends dictated our perception of what is natural to kins, including our core beliefs about their psychological development. Take the toddler. I assumed that phase was something experts develop ed after years of research into children’s behavior: wrong. Turns out, acdording to Daniel Cook, a historian of childhood consumerism, it was popularised as a marketing trick by clothing manufacturers in the 1930s.Trade publications counselled department stores that, in order to increase sales, they should create a “third stepping stone” between infant wear and older kids’ clothes. Tt was only after “toddler”became a common shoppers’ term that it evolved into a broadly accepted developmental stage. Splitting kids, or adults,into ever-tinier categories has proved a sure-fire way to boost profits. And one of the easiest ways to segment a market is to magnify gender differences – or invent them where they did not previously exist.26.By saying "it is...the rainbow"(Line 3, Para.1),the author means pink______.[A]should not be the sole representation of girlho od[B]should not be associated with girls' innocence[C]cannot explain girls' lack of imagination[D]cannot influence girls' lives and interests27.According to Paragraph 2, which of the following is true of colours?[A]Colours are encoded in girls' DNA.[B]Blue used to be regarded as the colour for girl s.[C]Pink used to be a neutral colour in symbolising genders.[D]White is prefered by babies.28.The author suggests that our perception of children's psychological development was much influenced by_____.[A]the marketing of products for childr en[B]the observation of children's nature[C]researches into children's behavior[D]studies of childhood consumption29.We may learn from Paragraph 4 that department stores were advised to_____.[A]focus on infant wear and older kids' clothes[B]attach equal importance to different genders[C]classify consumers into smaller group s[D]create some common shoppers' terms30.It can be concluded that girls' attraction to pink seems to be____.[A] clearly explained by their inborn tendency[B]fully understood by clothing manufacturers[C] mainly imposed by profit-driven businessm en[D]well interpreted by psychological expertsText3In2010.afederaljudgeshookAmerica'panieshadwonpatentsforisolatedDNAfor decades-by2005some20%ofhumangeneswereparented.ButinMarch2010ajudgeruledthatgeneswereun patentable.Executiveswereviolentlyagitated.TheBiotechnologyIndustryOr ganisation(BIO),atradegroup,assuredmembersthatthiswasjusta“prelimina rystep”inalongerbattle.OnJuly29ththeywererelieved,atleasttemporarily.Afederalappealscourtoverturnedthepriordecision,rulingthatMyriadGeneticscouldindeedholbpatent stotwogenssthathelpforecastawoman'sriskofbreastcancer.Thechiefexecuti veofMyriad,acompanyinUtah,saidtherulingwasablessingtofirmsandpatients alike.Butascompaniescontinuetheirattemptsatpersonalisedmedicine,thecourtswi llremainratherbusy.TheMyriadcaseitselfisprobablynotoverCriticsmakethr eemainargumentsagainstgenepatents:ageneisaproductofnature,soitmaynotb epatented;genepatentssuppressinnovationratherthanrewardit;andpatents' monopoliesrestrictaccesstogenetictestssuchasMyriad's.Agrowingnumberse styearafederaltask-forceurgedreformforpatentsrelatedtogen etictests.InOctobertheDepartmentofJusticefiledabriefintheMyriadcase,a rguingthatanisolatedDNAmolecule“isnolessaproductofnature...thanareco ttonfibresthathavebeensepar atedfromcottonseeds.”Despitetheappealscourt'sdecision,bigquestionsremainunanswered.Forexam ple,itisunclearwhetherthesequencingofawholegenomeviolatesthepatentsof individualgeneswithinit.ThecasemayyetreachtheSupremeCourt.AS the industry advances ,however,other suits may have an even greater panies are unlikely to file many more patents for human DNA molecules-most are already patented or in the public domain .firms are now studying how genes intcract,looking for correlations that might be used to determine the causes of disease or predict a drug’s efficacy,companies are eager to win patents for ‘connecting the dits’,expaains hans sauer,alawyer for the BIO.Their success may be determined by a suit related to this issue, brought by the Mayo Clinic, which the Supreme Court will hear in its next term.

Before it ends,it will likely change the life course and character of a generation of young adults. And ultimately, it is likely to reshape our politics,our culture, and the character of our society for years.No one tries harder than the jobless to find silver linings in this national economic disaster. Many said that unemployment, while extremely painful, had improved them in some ways; they had become less materialistic and more financially prudent; they were more aware of the struggles of others. In limited respects, perhaps the recession will leave society better off. At the very least, it has awoken us from our national fever dream of easy riches and bigger houses, and put a necessary end to an era of reckless personal spending.But for the most part, these benefits seem thin, uncertain, and far off. In The Moral Consequences of Economic Growth, the economic historian Benjamin Friedman argues that both inside and outside the U.S. ,lengthy periods of economic stagnation or decline have almost always left society more mean-spirited and less inclusive, and have usually stopped or reversed the advance of rights and freedoms. Anti-immigrant sentiment typically increases, as does conflict between races and classes.Income inequality usually falls during a recession, but it has not shrunk in this one,. Indeed, this period of economic weakness may reinforce class divides, and decrease opportunities to cross them--- especially for young people. The research of Till Von Wachter, the economist in Columbia University, suggests that not all people graduating into a recession see their life chances dimmed: those with degrees from elite universities catch up fairly quickly to where they otherwise would have been if they had graduated in better times; it is the masses beneath them that are left behind.In the internet age, it is particularly easy to see the resentment that has always been hidden winthin American society. More difficult, in the moment , is discerning precisely how these lean times are affecting society’s character. In many respects, the U.S. was more socially tolerant entering this resession than at any time in its history, and a variety of national polls on social conflict since then have shown mixed results. We will have to wait and see exactly how these hard times will reshape our social fabric. But they certainly it, and all the more so the longer they extend.36.By saying “to find silver linings”(Line 1,Para.2)the author suggest that the jobless try to___.[A]seek subsidies from the govemment[B]explore reasons for the unermployment[C]make profits from the troubled economy[D]look on the bright side of the recession37.According to Paragraph 2,the recession has made people_____.[A]realize the national dream[B]struggle against each other[C]challenge their lifestyle[D]reconsider their lifestyle38.Benjamin Friedman believe that economic recessions may_____.[A]impose a heavier burden on immigrants[B]bring out more evils of human nature[C]Promote the advance of rights and freedoms[D]ease conflicts between races and classes39.The research of Till Von Wachther suggests that in recession graduates from elite universities tend to _____.[A]lag behind the others due to decreased opportunities[B]catch up quickly with experienced employees[C]see their life chances as dimmed as the others’[D]recover more quickly than the others40.The author thinks that the influence of hard times on society is____.[A]certain[B]positive[C]trivial[D]destructivePart BDirections:Read the following text and answer the questions by finding information from the left column that corresponds to each of the marked details given in the right column.

Mark your answers on ANSWER SHEERT 1.(10 points)“Universal history, the history of what man has accomplished in this world, is at bottom the History of the Great Men who have worked here,” wrote the Victorian sage Thomas Carlyle. Well, not any more it is not.Suddenly, Britain looks to have fallen out with its favourite historical form. This could be no more than a passing literary craze, but it also points to a broader truth about how we now approach the past: less concerned with learning from forefathers and more interested in feeling their pain. Today, we want empathy, not inspiration.From the earliest days of the Renaissance, the writing of history meant recounting the exemplary lives of great men. In 1337, Petrarch began work on his rambling writing De Viris Illustribus – On Famous Men, highlighting the virtus (or virtue) of classical heroes. Petrarch celebrated their greatness in conquering fortune and rising to the top. This was the biographical tradition which Niccolo Machiavelli turned on its head. In The Prince, the championed cunning, ruthlessness, and boldness, rather than virtue, mercy and justice, as the skills of successful leaders.Over time, the attributes of greatness shifted. The Romantics commemorated the leading painters and authors of their day, stressing the uniqueness of the artist's personal experience rather than public glory. By contrast, the Victorian author Samual Smiles wrote Self-Help as a catalogue of the worthy lives of engineers , industrialists and explores . "The valuable examples which they furnish of the power of self-help, ifpatient purpose, resolute working and steadfast integrity, issuing in the formulation of truly noble and many character, exhibit,"wrote Smiles."what it is in the power of each to accomplish for himself"His biographies of James Walt, Richard Arkwright and Josiah Wedgwood were held up as beacons to guide the working man through his difficult life.This was all a bit bourgeois for Thomas Carlyle, who focused his biographies on the truly heroic lives of Martin Luther, Oliver Cromwell and Napoleon Bonaparte. These epochal figures represented lives hard to imitate, but to be acknowledged as possessing higher authority than mere mortals.Communist Manifesto. For them, history did nothing, it possessed no immense wealth nor waged battles:“It is man, real, living man who does all that.” And history should be the story of the masses and their record of struggle. As such, it needed to appreciate the economic realities, the social contexts and power relations in which each epoch stood. For:“Men make their own history, but they do not make it just as they please; they do not make it under circumstances chosen by themselves, but under circumstan ces directly found, given and transmitted from the past.”This was the tradition which revolutionized our appreciation of the past. In place of Thomas Carlyle, Britain nurtured Christopher Hill, EP Thompson and Eric Hobsbawm. History from below stood alongside biographies of great men. Whole new realms of understanding —from gender to race to cultural studies — were opened up as scholars unpicked the multiplicity of lost societies. And it transformed public history too: downstairs became just as fascinating as upstairs.Section III Translation46.Directions:Translate the following text from English into Chinese.Write your translation on ANSWER SHEET2.(15 points)When people in developing countries worry about migration,they are usually concerned at the prospect of ther best and brightest departure to Silicon Valley or to hospitals and universities in the developed world ,These are the kind of workers that countries like Britian ,Canada and Australia try to attract by using immigration rules that privilege college graduates .Lots of studies have found that well-educated people from developing countries are particularly likely to emigrate .A big survey of Indian households in 2004 found that nearly 40%of emigrants had more than a high-school education,compared with around 3.3%of all Indians over the age of 25.This "brain drain "has long bothered policymakers in poor countries ,They fear that it hurts their economies ,depriving them of much-needed skilled workers who could have taught at their universities ,worked in their hospitals and come up with clever new products for their factories to make .Section IV WritingPart A47.DirectionsSuppose you have found something wrong with the electronic dictionary that you bought from an onlin store the other day ,Write an email to the customer service center to1)make a complaint and2)demand a prompt solutionYou should write about 100words on ANSERE SHEET 2Do not sign your own name at the end of the letter ,Use "zhang wei "instead .48、write an essay based on the following table .In your writing you should1)describe the table ,and2)give your commentsYou should write at least 150 words(15points)英语二答案:完形填空:1.B2.B3.A4.A5.C6.B7.C8.A9.D 10.B11.D 12.B 13.C 14.D 15.B16.A 17.C 18.B 19.B 20.DTEXT1:21.

[A] it should be eliminated[B]it counts much in schooling[C]it places extra burdens on teachers[D]it is important for grades25.A suitable title for this text could be______.[A]Wrong Interpretation of an Educational Policy[B]A Welcomed Policy for Poor Students[C]Thorny Questions about Homework[D]A Faulty Approach to HomeworkText2Pretty in pink: adult women do not rememer being so obsessed with the colour, yet it is pervasive in our young girls’ lives. Tt is not that pink is intrinsically bad, but it is such a tiny slice of the rainbow and, though it may celebrate girlhood in one way, it also repe atedly and firmly fuses girls’ identity to appearance. Then it presents that connection, even among two-year-olds, between girls as not only innocent but as evidence of innocence. Looking around, I despaired at the singular lack of imagination about girls’ lives and interests.Girls’ attraction to pink may seem unavoidable, somehow encoded in their DNA, but according to Jo Paoletti, an associate professor of American Studies, it is not. Children were not colour-coded at all until the early 20th century: in the era before domestic washing machines all babies wore white as a practical matter, since the only way of getting clothes clean was to boil them. What’s more, both boys and girls wore what were thought of as gender-neutral dresses.When nursery colours were introduced, pink was actually considered the more masculine colour, a pastel version of red, which was associated with strength. Blue, with its intimations of the Virgin Mary, constancy and faithfulness, symbolised femininity. It was not until the mid-1980s, when amplifying age and sex differences became a dominant children’s marketing strategy, that pink fully came into its own,when it began to seem inherently attractive to girls, part of what defined them as female, at least for the first few critical years.I had not realised how profoundly marketing trends dictated our perception of what is natural to kins, including our core beliefs about their psychological development. Take the toddler. I assumed that phase was something experts developed after years of research into children’s behaviour: wrong. Turns out, acdording to Daniel Cook, a historian of childhood consumerism, it was popularised as a marketing trick by clothing manufacrurers in the 1930s.Trade publications counselled departme nt stores that, in order to increase sales, they should create a “third stepping stone” between infant wear and older kids’ clothes. Tt was only after “toddler”became a common shoppers’ term that it evolved into a broadly accepted developmental stage. Spli tting kids, or adults,intoever-tinier categories has proved a sure-fire way to boost profits. And one of the easiest ways to segment a market is to magnify gender differences – or invent them where they did not previously exist.26.By saying "it is...the rainbow"(Line 3, Para.1),the author means pink______.[A]should not be the sole representation of girlhood[B]should not be associated with girls' innocence[C]cannot explain girls' lack of imagination[D]cannot influence girls' lives and interests27.According to Paragraph 2, which of the following is true of colours?[A]Colours are encoded in girls' DNA.[B]Blue used to be regarded as the colour for girls.[C]Pink used to be a neutral colour in symbolising genders.[D]White is prefered by babies.28.The author suggests that our perception of children's psychological development was much influenced by_____.[A]the marketing of products for children[B]the observation of children's nature[C]researches into children's behavior[D]studies of childhood consumption29.We may learn from Paragraph 4 that department stores were advised to_____.[A]focus on infant wear and older kids' clothes[B]attach equal importance to different genders[C]classify consumers into smaller groups[D]create some common shoppers' terms30.It can be concluded that girls' attraction to pink seems to be____.[A] clearly explained by their inborn tendency[B]fully understood by clothing manufacturers[C] mainly imposed by profit-driven businessmen[D]well interpreted by psychological expertsText3In2010.afederaljudgeshookAmerica'panieshadwonpatentsforisolatedDNAfordeca des-by2005some20%ofhumangeneswereparented.ButinMarch2010ajudgeruledthatgeneswereunpatentable.Executiveswereviolently agitated.TheBiotechnologyIndustryOrganisation(BIO),atradegroup,assuredmembersthatthiswasjusta“preliminar ystep”inalongerbattle.OnJuly29ththeywererelieved,atleasttemporarily.Afederalappealscourtoverturnedthepriordecision,rulingthatMyri adGeneticscouldindeedholbpatentstotwogenssthathelpforecastawoman'sriskofbreastcancer.Thechiefexecutiveof Myriad,acompanyinUtah,saidtherulingwasablessingtofirmsandpatientsalike.

Before it ends,it will likely change the life course and character of a generation of young adults. And ultimately, it is likely to reshape our politics,our culture, and the character of our society for years.No one tries harder than the jobless to find silver linings in this national economic disaster. Many said that unemployment, while extremely painful, had improved them in some ways; they had become less materialistic and more financially prudent; they were more aware of the struggles of others. In limited respects, perhaps the recession will leave society better off. At the very least, it has awoken us from our national fever dream of easy riches and bigger houses, and put a necessary end to an era of reckless personal spending.But for the most part, these benefits seem thin, uncertain, and far off. In The Moral Consequences of Economic Growth, the economic historian Benjamin Friedman argues that both inside and outside the U.S. ,lengthy periods of economic stagnation or decline have almost always left society more mean-spirited and less inclusive, and have usually stopped or reversed the advance of rights and freedoms. Anti-immigrant sentiment typically increases, as does conflict between races and classes.Income inequality usually falls during a recession, but it has not shrunk in this one,. Indeed, this period of economic weakness may reinforce class divides, and decrease opportunities to cross them--- especially for young people. The research of Till Von Wachter, the economist in Columbia University, suggests that not all people graduating into a recession see their life chances dimmed: those with degrees from elite universities catch up fairly quickly to where they otherwise would have been if they had graduated in better times; it is the masses beneath them that are left behind.In the internet age, it is particularly easy to see the resentment that has always been hidden winthin American society. More difficult, in the moment , is discerning precisely how these lean times are affecting society’s character. In many respects, the U.S. was more socially tolerant entering this resession than at any time in its history, and a variety of national polls on social conflict since then have shown mixed results. We will have to wait and see exactly how these hard times will reshape our social fabric. But they certainly it, and all the more so the longer they extend.36.By saying “to find silver linings”(Line 1,Para.2)the author suggest that the jobless try to___.[A]seek subsidies from the govemment[B]explore reasons for the unermployment[C]make profits from the troubled economy[D]look on the bright side of the recession37.According to Paragraph 2,the recession has made people_____.[A]realize the national dream[B]struggle against each other[C]challenge their lifestyle[D]reconsider their lifestyle38.Benjamin Friedman believe that economic recessions may_____.[A]impose a heavier burden on immigrants[B]bring out more evils of human nature[C]Promote the advance of rights and freedoms[D]ease conflicts between races and classes39.The research of Till Von Wachther suggests that in recession graduates from elite universities tend to _____.[A]lag behind the others due to decreased opportunities[B]catch up quickly with experienced employees[C]see their life chances as dimmed as the others’[D]recover more quickly than the others40.The author thinks that the influence of hard times on society is____.[A]certain[B]positive[C]trivial[D]destructivePart BDirections:Read the following text and answer the questions by finding information from the left column that corresponds to each of the marked details given in the right column.

Mark your answers on ANSWER SHEERT 1.(10 points)“Universal history, the history of what man has accomplished in this world, is at bottom the History of the Grea t Men who have worked here,” wrote the Victorian sage Thomas Carlyle. Well, not any more it is not.Suddenly, Britain looks to have fallen out with its favourite historical form. This could be no more than a passing literary craze, but it also points to a broader truth about how we now approach the past: less concerned with learning from forefathers and more interested in feeling their pain. Today, we want empathy, not inspiration.From the earliest days of the Renaissance, the writing of history meant recounting the exemplary lives of great men. In 1337, Petrarch began work on his rambling writing De Viris Illustribus –On Famous Men, highlighting the virtus (or virtue) of classical heroes. Petrarch celebrated their greatness in conquering fortune and rising to the top. This was the biographical tradition which Niccolo Machiavelli turned on its head. In The Prince, the championed cunning, ruthlessness, and boldness, rather than virtue, mercy and justice, as the skills of successful leaders.Over time, the attributes of greatness shifted. The Romantics commemorated the leading painters and authors of their day, stressing the uniqueness of the artist's personal experience rather than public glory. By contrast, the Victorian author Samual Smiles wrote Self-Help as a catalogue of the worthy lives of engineers , industrialists and explores . "The valuable examples which they furnish of the power of self-help, if patient purpose, resolute working and steadfast integrity, issuing in the formulation of truly noble and many character, exhibit,"wrote Smiles."what it is in the power of each to accomplish for himself"His biographies of James Walt, Richard Arkwright and Josiah Wedgwood were held up as beacons to guide the working man through his difficult life.This was all a bit bourgeois for Thomas Carlyle, who focused his biographies on the truly heroic lives of Martin Luther, Oliver Cromwell and Napoleon Bonaparte. These epochal figures represented lives hard to imitate, but to be acknowledged as possessing higher authority than mere mortals.Communist Manifesto. For them, history did nothing, it possessed no immense wealth nor waged battles:“It is man, real, living man who does all that.” And history should be the story of the masses and their record of struggle. As such, it needed to appreciate the economic realities, the social contexts and power relations in which each epoch stood. For:“Men make their own history, but they do not make it just as they please; they do not make it under circumstances chosen by themselves, but under circumstances directly found, given and transmitted from the past.”This was the tradition which revolutionized our appreciation of the past. In place of Thomas Carlyle, Britain nurtured Christopher Hill, EP Thompson and Eric Hobsbawm. History from below stood alongside biographies of great men. Whole new realms of understanding — from gender to race to cultural studies —were opened up as scholars unpicked the multiplicity of lost societies. And it transformed public history too: downstairs became just as fascinating as upstairs.Section III Translation46.Directions:Translate the following text from English into Chinese.Write your translation on ANSWER SHEET2.(15 points)When people in developing countries worry about migration,they are usually concerned at the prospect of ther best and brightest departure to Silicon Valley or to hospitals and universities in the developed world ,These are the kind of workers that countries like Britian ,Canada and Australia try to attract by using immigration rules that privilege college graduates .Lots of studies have found that well-educated people from developing countries are particularly likely to emigrate .A big survey of Indian households in 2004 found that nearly 40%of emigrants had more than a high-school education,compared with around 3.3%of all Indians over the age of 25.This "brain drain "has long bothered policymakers in poor countries ,They fear that it hurts their economies ,depriving them of much-needed skilled workers who could have taught at their universities ,worked in their hospitals and come up with clever new products for their factories to make .Section IV WritingPart A47.DirectionsSuppose you have found something wrong with the electronic dictionary that you bought from an onlin store the other day ,Write an email to the customer service center to1)make a complaint and2)demand a prompt solutionYou should write about 100words on ANSERE SHEET 2Do not sign your own name at the end of the letter ,Use "zhang wei "instead .48、write an essay based on the following table .In your writing you should1)describe the table ,and2)give your commentsYou should write at least 150 words(15points)英语二答案:完形填空:1.B2.B3.A4.A5.C6.B7.C8.A9.D 10.B11.D 12.B 13.C 14.D 15.B16.A 17.C 18.B 19.B 20.DTEXT1:21.

2012年全国硕⼠研究⽣⼊学统⼀考试政治试题答案详解 ⼀、单项选择题:1~16⼩题,每⼩题1分,共16分。

下列每题给出的四个选项中,只有⼀个选项是符合题⽬要求的。

请在答题卡上将所选项的字母涂⿊。

1.【答案】A 【解析】 2.【答案】A 【解析】 3.【答案】B 【解析】 4.【答案】C 【解析】 5.【答案】D 【解析】 6.【答案】D 【解析】本题考查公有制的实现形式,巩固和发展公有制经济,还要努⼒寻找能够极⼤促进⽣产⼒发展的公有制实现形式。

公有制经济的性质和实现形式是两个不同层次的问题。

公有制经济的性质体现在所有权的归属上,坚持公有制的性质,根本的是坚持国家和集体对⽣产资料的所有权。

所有制作为⽣产关系的基础,有公有制与私有制、社会主义与资本主义的区别。

⽽所有制的实现形式是采取怎样的经营⽅式和组级形式问题,它不具有“公”与“私”、“社”与“资”的区分。

同样的所有制可以采取不同的实现形式,⽽不同的所有制可以采取相同的实现形式。

因为实现形式要解决的是发展⽣产⼒的组织形式和经营⽅式问题,只要能够有利于⽣产⼒的发展,公有制的实现形式可以⽽且应当多样化,⼀切反映社会化⽣产规律的经营⽅式和组织形式都可以⼤胆利⽤。

要根据社会化⽣产规律的要求,采取多样化的经营⽅式和资产组织形式,使国有经济在更⼤的范围⾥获得⼴阔的发展空间。

其中的第三条表⽰:保障⼈⼤代表依法⾏使职权,密切⼈⼤代表同⼈民的联系,建议逐步实⾏城乡按相同⼈⼝⽐例选举⼈⼤代表,因此B选项更加体现出党的民主与群众路线的内容。

8.【答案】B 【解析】此题考查民主区域⾃治制度的历史依据。

实⾏民族区域⾃治,是党棍据我国的历史发展、⽂化特点、民族关系和民族分布等具体情况作出的制度安排,符合各民族⼈民的共同利益和发展要求。

统⼀的多民族国家的长期存在和发展,是我国实⾏民族区域⾃治的历史依据。

School districts across the country, most recently Los Angeles Unified, are revising their thinking on his educational ritual. Unfortunately, L.A. Unified has produced an inflexible policy which mandates that with the exception of some advanced courses, homework may no longer count for more than 10% of a student grade.This rule is meant to address the difficulty that students from impoverished or chaotic homes might have in completing their homework. But the policy is unclear and contradictory. Certainly, no homework should be assigned that students cannot do without expensive equipment. But if the district is essentially giving a pass to students who do not do their homework because of complicated family lives, it is going riskily close to the implication that standards need to be lowered for poor children.District administrators say that homework will still be a pat of schooling: teachers are allowed to assign as much of it as they want. But with homework counting for no more than 10% of their grades, students can easily skip half their homework and see vey little difference on their report cards. Some students might do well on state tests without completing their homework, but what about the students who performed well on the tests and did their homework? It is quite possible that the homework helped. Yet rather than empowering teachers to find what works best for their students, the policy imposes a flat, across-the-board rule.At the same time, the policy addresses none of the truly thorny questions about homework. If the district finds homework to be unimportant to its students a 'cademic achievement, it should move to reduce or eliminate the assignments, not make them count for almost nothing. Conversely, if homework does nothing to ensure that the homework students are not assigning more than they are willing to review and correct.The homework rules should be put on hold while the school board, which is responsible for settingeducational policy, looks into the matter and conducts public hearings. It is not too late for L.A. Unified to do homework right.21.lt is implied in paragraph 1 that no wadays homework ____ .[A] is receivi ng more criticism[B] is no Ion ger an educati onal ritual[C] is not required for adva need courses 11.

It isn ovesat pink in tr in sically bad, but it is a tiny slice of the rain bow and, though it may celebrate girlhood in one way, it also repeatedly and firmly fused girls identity to appearanee. Then it presents that connection, even among two-year-olds, between girls as not only innocent but as evidenee of innocence. Looking around, despaired at the sin gular lack of imagi nati on about girls ' lives and in terests.Girls' attract ion to pi nk may seem un avoidable, somehow en coded in their DNA, but accord ing to Jo Paoletti, an associate professor of America n Studies, it's not. Childre n were not colour-coded at all until the early 20th century: in the era before domestic washing machines all babies wore white as a practical matter, since the only way of getting clothes clean was to boil them. What's more, both boys and girls wore what were thought of as gen der -n eutral dresses. Whe n n ursery colours were in troduced, pink was actually con sidered the more masculi ne colour, a pastel vers ion of red, which was associated with stre ngth. Blue, with its intimations of the Virgin Mary, constancy and faithfulness, symbolised femininity. It was not until the mid-1980s, when amplifying age and sex differences became a dominant children's marketing strategy, that pink fully came into its own, when it began to seem innately attractive to girls, part of what defined them as female, at least for the first few critical years.I had not realised how profoundly marketing trends dictated our perception of what is natural to kids, including our core beliefs about their psychological development. Take the toddler. I assumed that phase was something experts developed after years of research into children's behaviour: wrong. Turns out, according to Daniel Cook, a historian of childhood consumerism, it was popularised as a marketing gimmick by clothing manufacturers in the 1930s.Trade publications counseled department stores that, in order to increase sales, they should create a "third stepping stone" between infant wear and older kids' clothes. It was only after "toddler" became common shoppers'term that it evolved into a broadly accepted developmental stage. Splitting kids, or adults, into ever-tinier categories has proved a sure-fire way to boost profits. And one of the easiest ways to segment a market is to magnify gender differe nces -or invent them where they did not previously exist.26. By saying "it is ... The rainbow"(line 3, Para 1), the author means pink ______ .A should not be the sole representation of girlhoodB should not be associated with girls' innocenceC cannot explain girls' lack of imaginationD cannot influence girls' lives and interests27. According to Paragraph 2, which of the following is true of colours?A Colors are encoded in girls' DNAB Blue used to be regarded as the color for girlsC Pink used to be a neutral color in symbolizing gendersD White is preferred by babies28. The author suggests that our perception of children's psychological devotement was muchinfluenced by _______ .[A] the marketing of products for children[B] the observation of children's nature[C] researches into children's behavior[D] studies of childhood consumption29. We may learn from Paragraph 4 that department stores were advised ______ .A focuses on infant wear and older kids' clothesB attach equal importance to different gendersC classify consumers into smaller groupsD create some common shoppers' terms30. It can be concluded that girl's attraction to pink seems to be ___ .A clearly explained by their inborn tendencyB fully understood by clothing manufacturersC mainly imposed by profit-driven businessmenD well interpreted by psychological expertsText 3In 2010. a federal judge shook America's biotech industry to its core. Companies had won patents for isolated DNA for decades-by 2005 some 20% of human genes were patented. But in March 2010 a judge ruled that genes were unpatentable. Executives were violently agitated. The Biotechnology Industry Organisation (BIO), a trade group, assured members that this was just a “ preliminary step ” in a longer battle.On July 29th they were relieved, at least temporarily. A federal appeals court overturned the prior decision, ruling that Myriad Genetics could indeed hold patents to two genes that help forecast a woman's risk of breast cancer. The chief executive of Myriad, a company in Utah, said the ruling was a blessing to firms and patients alike.But as companies continue their attempts at personalised medicine, the courts will remain rather busy. The Myriad case itself is probably not over. Critics make three main arguments against gene patents: a gene is a product of nature, so it may not be patented; gene patents suppress innovation rather than reward it; and patents' monopolies restrict access to genetic tests such as Myriad's. A growing number seem to agree. Last year a federal task-force urged reform for patents related to genetic tests. In October the Department of Justice filed a brief in the Myriad case, arguing that an isolated DNA molecule “isno less a product of nature... than are cotton fibres that have been separated from cotton seeds.Despite the appeals court's decision, big questions remain unanswered. For example, it is unclear whether the sequencing of a whole genome violates the patents of individual genes within it. The case may yet reach the Supreme Court.AS the industry advances, however, other suits may have an even greater impact. Companies are unlikely to file many more patents for human DNA molecules - most are already patented or in the public domain .firms arenow studying how genes interact, looking for correlations that might be used to determine the causes of disease or predict a drug ' s efficacy. Companies are eager to win patents for ‘ connecting the dots er, a ' lawyer for the BIO., explains Hans S Their success may be determined by a suit related to this issue, brought by the Mayo Clinic, which the Supreme Court will hear in its next term. The BIO recently held a convention which included sessions to coach lawyers on the shifting landscape for patents. Each meeting was packed.31. It can be learned from paragraph I that the biotech companies would like ____A. their executives to be activeB. judges to rule out gene patentingC. genes to be patentableD. the BIO to issue a warning32. Those who are against gene patents believe that ___A. genetic tests are not reliableB. only man-made products are patentableC. patents on genes depend much on innovationsD. courts should restrict access to genetic tests33. According to Hans Sauer, companies are eager to win patents for ____A. establishing disease correlationsB. discovering gene interactionsC. drawing pictures of genesD. identifying human DNA34.By saying “each meeting was packed ” (line4,para6)the author means that _________A. the Supreme Court was authoritativeB. the BIO was a powerful organizationC. gene patenting was a great concernD. lawyers were keen to attend conventions35. Generally speaking, the author ' s attitude toward gene patenting is _______A. criticalB. supportiveC. scornfulD. objectiveText 4The great recession may be over, but this era of high joblessness is probably beginning. Before it ends, It will likely change the life course and character of a generation of young adults. And ultimately, it is likely to reshape our politics, our culture, and the character of our society for years.No one tries harder than the jobless to find silver linings in this national economic disaster. Many said that unemployment, while extremely painful, had improved them in some ways; they had become less materialistic and more financially prudent; they were more aware of the struggles of others. In limited respects, perhaps the recession will leave society better off. At the very least, it has awoken us from our national fever dream of easy riches and bigger houses, and put a necessary end to an era of reckless personal spending.But for the most part, these benefits seem thin, uncertain, and far off. In The Moral Consequences of Economic Growth, the economic historian Benjamin Friedman argues that both inside and outside the U.S. , lengthy periods of economic stagnation or decline have almost always left society more mean-spirited and less inclusive, and have usually stopped or reversed the advance of rights and freedoms. Anti-immigrant sentiment typically increases, as does conflict between races and classes.Income inequality usually falls during a recession, but it has not shrunk in this one. Indeed, this period of economic weakness may reinforce class divides, and decrease opportunities to cross them--- especially for young people. The research of Till Von Wachter, the economist in Columbia University, suggests that not all people graduating into a recession see their life chances dimmed: those with degrees from elite universities catch up fairly quickly to where they otherwise would have been if they had graduated in better times; it is the masses beneath them that are left behind.In the internet age, it is particularly easy to see the resentment that has always been hiddenwithin American society. More difficult, in the moment, is discerning precisely how these leantimes are affecting society 'chsaracter. In many respects, the U.S. was more socially tolerantentering this recession than at any time in its history, and a variety of national polls on socialconflict since then have shown mixed results. We will have to wait and see exactly how thesehard times will reshape our social fabric. But they certainly it, and all the more so the longerthey extend.36. By saying “to find silver lining(s Line 1,Para”.2)the author suggest that the jobless tryto___.[A] s eek subsidies from the government[B] e xplore reasons for the unemployment[C] m ake profits from the troubled economy[D] l ook on the bright side of the recession37. According to Paragraph 2,the recession has made people ____ .[A] r ealize the national dream[B] s truggle against each other[C] c hallenge their lifestyle[D] r econsider their lifestyle38. Benjamin Friedman believed that economic recession may ___ .[A] i mpose a heavier burden on immigrants[B] b ring out more evils of human nature[C] P romote the advance of rights and freedoms[D] e ase conflicts between races and classes39. The research of Till Von Wachther suggests that in recession graduates from elite universities tend to .[A] l ag behind the others due to decreased opportunities[B] c atch up quickly with experienced employees[C] see their life chances as dimmed as the others'[D] r ecover more quickly than the others40.

Mark your answers on ANSWER SHEERT 1.(10 points)Universal history, the history of what man has accomplished in this world, is at bottom the History of the Great Men who have worked here, ” wrote the Victorian sage Thomas Carlyle.Well, not any more it is not.Suddenly, Britain looks to have fallen out with its favourite historical form. This could be no more than a passing literary craze, but it also points to a broader truth about how we now approach the past: less concerned with learning from forefathers and more interested in feeling their pain. Today, we want empathy, not inspiration.From the earliest days of the Renaissance, the writing of history meant recounting the exemplary lives of great men. In 1337, Petrarch began work on his rambling writing De Viris Illustribus - On Famous Men, highlighting the virtus (or virtue) of classical heroes. Petrarch celebrated their greatness in conquering fortune and rising to the top. This was the biographical tradition which Niccolo Machiavelli turned on its head. In The Prince, the championed cunning, ruthlessness, and boldness, rather than virtue, mercy and justice, as the skills of successful leaders.Over time, the attributes of greatness shifted. The Romantics commemorated the leading painters and authors of their day, stressing the uniqueness of the artist's personal experience rather than public glory. By contrast, the Victorian author Samual Smiles wrote Self-Help as a catalogue of the worthy lives of engineers , industrialists and explores . "The valuable examples which they furnish of the power of self-help, if patient purpose, resolute working and steadfast integrity, issuing in the formulation of truly noble and many character, exhibit,"wrote Smiles."what it is in the power of each to accomplish for himself." His biographies of James Walt, Richard Arkwright and Josiah Wedgwood were held up as beacons to guide the working man through his difficult life.This was all a bit bourgeois for Thomas Carlyle, who focused his biographies on the truly heroic lives of Martin Luther, Oliver Cromwell and Napoleon Bonaparte. These epochal figures represented lives hard to imitate, but to be acknowledged as possessing higher authority than mere mortals.Communist Manifesto. For them, history did nothing, it possessed no immense wealth nor waged battles:“ It is man, real, living man who does all that. ” And history should b story of the masses and their record of struggle. As such, it needed to appreciate the economic realities, the social contexts and power relations in which each epoch stood. For:“ Mtheir own history, but they do not make it just as they please; they do not make it under circumstances chosen by themselves, but under circumstances directly found, given and transmitted from the past. ”This was the tradition which revolutionized our appreciation of the past. In place ofThomas Carlyle, Britain nurtured Christopher Hill, EP Thompson and Eric Hobsbawm. History from below stood alongside biographies of great men. Whole new realms of un dersta nding - from gen der to race to cultural studies - were ope ned up as scholars un picked the multiplicity of lost societies. And it transformed public history too: downstairs became just as fasci nati ng as upstairs.Part CDirecti ons:Read the following text carefully and then translate it into Chinese.

But in the everyday practice of science, discovery frequently follows an ambiguous and complicated route. We aim to be objective, but we cannot escape the context of our unique life experience. Prior knowledge and interest influence what we experience, what we think our experiences mean, and the subsequent actions we take. Opportunities for misinterpretation, error, and self-deception abound.Consequently, discovery claims should be thought of as protoscience. Similar to newly staked mining claims, they are full of potential. But it takes collective scrutiny and acceptance to transform a discovery claim into a mature discovery. This is the credibility process, through which the individual researcher’s me, here, now becomes the community’s anyone, anywhere, anytime. Objective knowledge i s the goal, not the starting point.Once a discovery claim becomes public, the discoverer receives intellectual credit. But, unlike with mining claims, the community takes control of what happens next. Within the complex social structure of the scientific community, researchers make discoveries; editors and reviewers act as gatekeepers by controlling the publication process; other scientists use the new finding to suit their own purposes; and finally, the public (including other scientists) receives the new discovery and possibly accompanying technology. As a discovery claim works it through the community, the interaction and confrontation between shared and competing beliefs about the science and the technology involved transforms an individual’s discovery claim into the community’s credible discovery.Two paradoxes exist throughout this credibility process. First, scientific work tends to focus on some aspect of prevailing Knowledge that is viewed as incomplete or incorrect. Little reward accompanies duplication and confirmation of what is already known and believed. The goal is new-search, not re-search. Not surprisingly, newly published discovery claims and credible discoveries that appear to be important and convincing will always be open to challenge and potential modification or refutation by future researchers. Second, novelty itself frequently provokes disbelief. Nobel Laureate and physiologist Albert Azent-Gyorgyi once described discovery as “seeing what everybody has seen and thinking what nobody has thought.” But thinking what nobody else has thought and telling others what they have missed may not change their views. Sometimes years are required for truly novel discovery claims to be accepted and appreciated.In the end, credibility “happens” to a d iscovery claim - a process that corresponds to what philosopher Annette Baier has described as the commons of the mind. “We reason together, challenge, revise, and complete each other’s reasoning and each other’s conceptions of reason.”31. According to the first paragraph, the process of discovery is characterized by its[A] uncertainty and complexity.[B] misconception and deceptiveness.[C] logicality and objectivity.[D] systematicness and regularity.32. It can be inferred from Paragraph 2 that credibility process requires[A] strict inspection.[B]shared efforts.[C] individual wisdom.[D]persistent innovation.33.Paragraph 3 shows that a discovery claim becomes credible after it[A] has attracted the attention of the general public.[B]has been examined by the scientific community.[C] has received recognition from editors and reviewers.[D]has been frequently quoted by peer scientists.34. Albert Szent-Gy?rgyi would most likely agree that[A] scientific claims will survive challenges.[B]discoveries today inspire future research.[C] efforts to make discoveries are justified.[D]scientific work calls for a critical mind.35.Which of the following would be the best title of the test?[A] Novelty as an Engine of Scientific Development.[B]Collective Scrutiny in Scientific Discovery.[C] Evolution of Credibility in Doing Science.[D]Challenge to Credibility at the Gate to Science.Text 4If the trade unionist Jimmy Hoffa were alive today, he would probably represent civil servant. When Hoffa’s Teamsters were in their prime in 1960, only one in ten American government workers belonged to a union; now 36% do. In 2009 the number of unionists in America’s public sector passed that of their fellow members in the private sector. In Britain, more than half of public-sector workers but only about 15% of private-sector ones are unionized.There are three reasons for the public-sector unions’ thriving. First, they can shut things down without suffering much in the way of consequences. Second, they are mostly bright and well-educated. A quarter of America’s public-sector workers have a university degree. Third, they now dominate left-of-centre politics. Some of their ties go back a long way. Britain’s Labor Party, as its name implies, has long been associated with trade unionism. Its current leader, Ed Miliband, owes his position to votes from public-sector unions.At the state level their influence can be even more fearsome. Mark Baldassare of the Public Policy Institute of California points out that much of the state’s budget is patrolled by unions. The teachers’ unions keep an eye on schools, the CCPOA on prisons and a variety of labor groups on health care.In many rich countries average wages in the state sector are higher than in the private one. But the real gains come in benefits and work practices. Politicians have repeatedly “backloaded” public-sector pay deals, keeping the pay increases modest but adding to holidays and especially pensions that are already generous.Reform has been vigorously opposed, perhaps most egregiously in education, where charter schools, academies and merit pay all faced drawn-out battles. Even though there is plenty of evidence that the quality of the teachers is the most important variable, teachers’ unions have fought against getting r id of bad ones and promoting good ones.As the cost to everyone else has become clearer, politicians have begun to clamp down. In Wisconsin the unions have rallied thousands of supporters against Scott Walker, the hardline Republican governor. But many within the public sector suffer under the current system, too.John Donahue at Harvard’s Kennedy School points out that the norms of culture in Western civil services suit those who want to stay put but is bad for high achievers. The only American public-sector workers who earn well above $250,000 a year are university sports coaches and the president of the United States. Bankers’ fat pay packets have attracted much criticism, but a public-sector system that does not reward high achievers may be a much bigger problem for America.36. It can be learned from the first paragraph that[A] Teamsters still have a large body of members.[B] Jimmy Hoffa used to work as a civil servant.[C] unions have enlarged their public-sector membership.[D]the government has improved its relationship with unionists.37. Which of the following is true of Paragraph 2?[A] Public-sector unions are prudent in taking actions.[B] Education is required for public-sector union membership.[C] Labor Party has long been fighting against public-sector unions.[D]Public-sector unions seldom get in trouble for their actions.38. It can be learned from Paragraph 4 that the income in the state sector is[A] illegally secured.[B] indirectly augmented.[C] excessively increased.[D]fairly adjusted.39. The example of the unions in Wisconsin shows that unions[A]often run against the current political system.[B]can change people’s political attitudes.[C]may be a barrier to public-sector reforms.[D]are dominant in the government.40. John Donahue’s attitude towards the public-sector system is one of[A]disapproval.[B]appreciation.[C]tolerance.[D]indifference.Part BDirections:In the following text, some sentences have been removed.

Mark your answers on ANSWER SHEET1.(10 points)Think of those fleeting moments when you look out of an aeroplane window and realise that you are flying, higher than a bird. Now think of your laptop, thinner than a brown-paper envelope, or your cellphone in the palm of your hand. Take a moment or two to wonder at those marvels. You are the lucky inheritor of a dream come true.The second half of the 20th century saw a collection of geniuses, warriors, entrepreneurs and visionaries labour to create a fabulous machine that could function as a typewriter and printing press, studio and theatre, paintbrush and gallery, piano and radio, the mail as well as the mail carrier. (41)The networked computer is an amazing device, the first media machine that serves as the mode of production, means of distribution, site of reception, and place of praise and critique. The computer is the 21st century's culture machine.But for all the reasons there are to celebrate the computer, we must also tread with caution. (42)I call it a secret war for two reasons. First, most people do not realise that there are strong commercial agendas at work to keep them in passive consumption mode. Second, the majority of people who use networked computers to upload are not even aware of the significance of what they are doing.All animals download, but only a few upload. Beavers build dams and birds make nests. Yet for the most part, the animal kingdom moves through the world downloading. Humans are unique in their capacity to not only make tools but then turn around and use them to create superfluous material goods - paintings, sculpture and architecture - and superfluous experiences - music, literature, religion and philosophy. (43)For all the possibilities of our new culture machines, most people are still stuck in download mode. Even after the advent of widespread social media, a pyramid of production remains, with a small number of people uploading material, a slightly larger group commenting on or modifying that content, and a huge percentage remaining content to just consume. (44)Television is a one-way tap flowing into our homes. The hardest task that television asks of anyone is to turn the power off after he has turned it on.(45)What counts as meaningful uploading? My definition revolves around the concept of "stickiness" - creations and experiences to which others adhere.[A] Of course, it is precisely these superfluous things that define human culture and ultimately what it is to be human. Downloading and consuming culture requires great skills, but failing to move beyond downloading is to strip oneself of a defining constituent of humanity.[B] Applications like , which allow users to combine pictures, words and other media in creative ways and then share them, have the potential to add stickiness by amusing, entertaining and enlightening others.[C] Not only did they develop such a device but by the turn of the millennium they had also managed to embed it in a worldwide system accessed by billions of people every day.[D] This is because the networked computer has sparked a secret war between downloading and uploading - between passive consumption and active creation - whose outcome will shape our collective future in ways we can only begin to imagine.[E] The challenge the computer mounts to television thus bears little similarity to one format being replaced by another in the manner of record players being replaced by CD players.[F] One reason for the persistence of this pyramid of production is that for the past half-century, much of the world's media culture has been defined by a single medium - television - and television is defined by downloading.[G]The networked computer offers the first chance in 50 years to reverse the flow, to encourage thoughtful downloading and, even more importantly, meaningful uploading.Part CDirections:Read the following text carefully and then translate the underlined segments into Chinese. Your translationshould be written clearly on ANSWER SHEET 2. (10 points)Since the days of Aristotle, a search for universal principles has characterized the scientific enterprise. In some ways, this quest for commonalities defines science. N ewton’s laws of motion and Darwinian evolution each bind a host of different phenomena into a single explicatory frame work.(46)In physics, one approach takes this impulse for unification to its extreme, and seeks a theory of everything-a single generative equation for all we see.It is becoming less clear, however, that such a theory would be a simplification, given the dimensions and universes that it might entail, nonetheless, unification of sorts remains a major goal.This tendency in the natural sciences has long been evident in the social sciences too. (47)Here, Darwinism seems to offer justification for it all humans share common origins it seems reasonable to suppose that cultural diversity could also be traced to more constrained beginnings.Just as the bewildering variety of human courtship rituals might all be considered forms of sexual selection, perhaps the world’s languages, music, social and religious customs and even history are governed by universal features. (48)To filter out what is unique from what is shared might enable us to understand how complex cultural behavior arose and what guides it in evolutionary or cognitive terms.That, at least, is the hope. But a comparative study of linguistic traits published online today supplies a reality check. Russell Gray at the University of Auckland and his colleagues consider the evolution of grammars in the light of two previous attempts to find universality in language.The most famous of these efforts was initiated by Noam Chomsky, who suggested that humans are born with an innate language-acquisition capacity that dictates a universal grammar. A few generative rules are then sufficient to unfold the entire fundamental structure of a language, which is why children can learn it so quickly.(49)The second, by Joshua Greenberg, takes a more empirical approach to universality identifying traits (particularly in word order) shared by many language which are considered to represent biases that result from cognitive constraintsGray and his colleagues have put them to the test by examining four family trees that between them represent more than 2,000 languages.(50)Chomsky’s grammar should show patterns of language change that are independent of the family tree or the pathway tracked through it. Whereas Greenbergian universality predicts strong co-dependencies between particular types of word-order relations. Neither of these patterns is borne out by the analysis, suggesting that the structures of the languages are lire age-specific and not governed by universalsSection III WritingPart A51.
