ComprehensionPart ADirections：Read the following four texts.Answer the questions after each text by choosing A,B, C or D.Mark your answers on ANSWER SHEET1.(40points)Text1In the2006film version of The Devil Wears Prada,Miranda Priestly,played by Meryl Streep, scold her unattractive assistant for imagining that high fashion doesn’t affect her.Priestly explains how the deep blue color of the assistant’s sweater descended over the years from fashion shows to department stores and to the bargain bin in which the poor girl doubtless found her garment.This top-down conception of the fashion business couldn’t be more out of date or at odds with feverish world described in Overdressed,Elizabeth Cline’s three-year indictment of“fast fashion”.In the last decades or so,advances in technology have allowed mass-market labels such as Zara,H&M, and Uniqlo to react to trends more quickly and anticipate demand more precisely.Quckier turnrounds mean less wasted inventory,more frequent releases,and more profit.Those labels encouragestyle-conscious consumers to see clothes as disposal——meant to last only a wash or two,although they don’t advertise that——and to renew their wardrobe every few weeks.By offering on-trend items at dirt-cheap prices,Cline argues,these brands have hijacked fashion cycles,shaking all industry long accustomed to a seasonal pace.The victims of this revolution,of course,are not limited to designers.For H&M to offer a5.95 knit miniskirt in all its2300-plus stores around the world,it must rely on low-wage,overseas labor, order in volumes that strain natural resources,and use massive amount of harmful chemicals.Overdressed is the fashion world’s answer to consumer activist bestsellers like Michael Pollan’s The Omnivore’s Dilemma.Mass-produced clothing,like fast food,fills a hunger and need,yet isnon-durable,and wasteful,”Cline argues,Americans,she finds,buy roughly20billion garments ayear——about64items per person——and no matter how much they give away,this excess leads to waste.Towards the end of Overdressed,Cline introduced her ideal,a Brooklyn woman named SKB,who, since2008has make all of her own clothes——and beautifully.But as Cline is the first to note,it took Beaumont decades to perfect her craft;her example,can’t be knocked off.Though several fast-fashion companies have made efforts to curb their impact on labor and the environment——including H&M,with its green Conscious Collection Line——Cline believes lasting-change can only be effected by the customer.She exhibits the idealism common to many advocates of sustainability,be it in food or in energy.Vanity is a constant;people will only start shopping more sustainably when they can’t afford to it.21.Priestly criticizes her assistant for her[A]poor bargaining skill.[B]insensitivity to fashion.[C]obsession with high fashion.[D]lack of imagination.22.According to Cline,mass-maket labels urge consumers to[A]combat unnecessary waste.[B]shut out the feverish fashion world.[C]resist the influence of advertisements.[D]shop for their garments more frequently.23.The word“indictment”(Line3,Para.2)is closest in meaning to[A]accusation.[B]enthusiasm.[C]indifference.[D]tolerance.24.Which of the following can be inferred from the lase paragraph?[A]Vanity has more often been found in idealists.[B]The fast-fashion industry ignores sustainability.[C]People are more interested in unaffordable garments.[D]Pricing is vital to environment-friendly purchasing.25.What is the subject of the text?[A]Satire on an extravagant lifestyle.[B]Challenge to a high-fashion myth.[C]Criticism of the fast-fashion industry.[D]Exposure of a mass-market secret.Text2An old saying has it that half of all advertising budgets are wasted-the trouble is,no one knows which half.In the internet age,at least in theory,this fraction can be much reduced.By watching what people search for,click on and say online,companies can aim“behavioural”ads at those most likely to buy.In the past couple of weeks a quarrel has illustrated the value to advertisers of such fine-grained information:Should advertisers assume that people are happy to be tracked and sent behavioural ads? Or should they have explicit permission?In December2010America's Federal Trade Cornmission(FTC)proposed adding a"do not track "(DNT)option to internet browsers,so that users could tell adwertisers that they did not want to be followed.Microsoft's Internet Explorer and Apple's Safari both offer DNT;Google's Chrome is due to do so this year.In February the FTC and Digltal Adwertising Alliance(DAA)agreed that the industry would get cracking on responging to DNT requests.On May31st Microsoft Set off the row:It said that Internet Explorer10,the version due to appear windows8,would have DNT as a default.It is not yet clear how advertisers will respond.Geting a DNT signal does not oblige anyone to stop tracking,although some companies have promised to do so.Unable to tell whether someone really objects to behavioural ads or whether they are sticking with Microsoft’s default,some may ignore a DNT signal and press on anyway.Also unclear is why Microsoft has gone it alone.Atter all,it has an ad business too,which it says will comply with DNT requests,though it is still working out how.If it is trying to upset Google, which relies almost wholly on default will become the norm.DNT does not seem an obviously huge selling point for windows8-though the firm has compared some of its other products favourably with Google's on that count before.Brendon Lynch,Microsoft's chief privacy officer,bloggde:"we believe consumers should have more control."Could it really be that simple?26.It is suggested in paragraph1that“behavioural”ads help advertisers to:[A]ease competition among themselves[B]lower their operational costs[C]avoid complaints from consumers[D]provide better online services27.“The industry”(Line6,Para.3)refers to:[A]online advertisers[B]e-commerce conductors[C]digital information analysis[D]internet browser developers28.Bob Liodice holds that setting DNT as a default[A]many cut the number of junk ads[B]fails to affect the ad industry[C]will not benefit consumers[D]goes against human nature29.which of the following is ture according to Paragraph.6?[A]DNT may not serve its intended purpose[B]Advertisers are willing to implement DNT[C]DNT is losing its popularity among consumers[D]Advertisers are obliged to offer behavioural ads30.The author's attitude towards what Brendon Lynch said in his blog is one of:[A]indulgence[B]understanding[C]appreciaction[D]skepticismText3Up until a few decades ago,our visions of the future were largely-though by no means uniformly -glowingly positive.Science and technology would cure all the ills of humanity,leading to lives of fulfillment and opportunity for all.Now utopia has grown unfashionable,as we have gained a deeper appreciation of the range of threats facing us,from asteroid strike to epidemic flu and to climate change.You might even be tempted to assume that humanity has little future to look forward to.But such gloominess is misplaced.The fossil record shows that many species have endured for millions of years-so why shouldn't we?Take a broader look at our species'place in the universe,and it becomes clear that we have an excellent chance of surviving for tens,if not hundreds,of thousandsof years.Look up Homo sapiens in the"Red List"of threatened species of the International Union for the Conversation of Nature(IUCN),and you will read:"Listed as Least Concern as the species is very widely distributed,adaptable,currently increasing,and there are no major threats resulting in an overall population decline."So what does our deep future hold?A growing number of researchers and organisations are now thinking seriously about that question.For example,the Long Now Foundation has its flagship project a medical clock that is designed to still be marking time thousands of years hence.Perhaps willfully,it may be easier to think about such lengthy timescales than about the more immediate future.The potential evolution of today's technology,and its social consequences,is dazzlingly complicated,and it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage.That's one reason why we have launched Arc,a new publication dedicated to the near future.But take a longer view and there is a surprising amount that we can say with considerable assurance.As so often,the past holds the key to the future:we have now identified enough of thelong-term patterns shaping the history of the planet,and our species,to make evidence-based forecasts about the situations in which our descendants will find themselves.This long perspective makes the pessimistic view of our prospects seem more likely to be a passing fad. To be sure,the future is not all rosy.But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans,and to improve the lot of those to come.31.Our vision of the future used to be inspired by[A]our desire for lives of fulfillment[B]our faith in science and technology[C]our awareness of potential risks[D]our belief in equal opportunity32.The IUCN’s“Red List”suggest that human being are[A]a sustained species[B]a threaten to the environment[C]the world’s dominant power[D]a misplaced race33.Which of the following is true according to Paragraph5?[A]Arc helps limit the scope of futurological studies.[B]Technology offers solutions to social problem.[C]The interest in science fiction is on the rise.[D]Our Immediate future is hard to conceive.34.To ensure the future of mankind,it is crucial to[A]explore our planet’s abundant resources[B]adopt an optimistic view of the world[C]draw on our experience from the past[D]curb our ambition to reshape history35.Which of the following would be the best title for the text?[A]Uncertainty about Our Future[B]Evolution of the Human Species[C]The Ever-bright Prospects of Mankind[D]Science,Technology and HumanityText4On a five to three vote,the Supreme Court knocked out much of Arizona’s immigration law Monday-a modest policy victory for the Obama Administration.But on the more important matter of the Constitution,the decision was an8-0defeat for the Administration’s effort to upset the balance of power between the federal government and the states.In Arizona v.United States,the majority overturned three of the four contested provisions of Arizona’s controversial plan to have state and local police enforce federal immigration law.The Constitutional principles that Washington alone has the power to“establish a uniform Rule of Naturalization”and that federal laws precede state laws are noncontroversial.Arizona had attempted to fashion state policies that ran parallel to the existing federal ones.Justice Anthony Kennedy,joined by Chief Justice John Roberts and the Court’s liberals,ruled that the state flew too close to the federal sun.On the overturned provisions the majority held the congress had deliberately“occupied the field”and Arizona had thus intruded on the federal’s privileged powers.However,the Justices said that Arizona police would be allowed to verify the legal status of people who come in contact with law enforcement.That’s because Congress has always envisioned joint federal-state immigration enforcement and explicitly encourages state officers to share information and cooperate with federal colleagues.Two of the three objecting Justice-Samuel Alito and Clarence Thomas-agreed with this Constitutional logic but disagreed about which Arizona rules conflicted with the federal statute.The only major objection came from Justice Antonin Scalia,who offered an even more robust defense of state privileges going back to the alien and Sedition Acts.The8-0objection to President Obama turns on what Justice Samuel Alito describes in his objection as“a shocking assertion assertion of federal executive power”.The White House argued that Arizona’s laws conflicted with its enforcement priorities,even if state laws complied with federal statutes to the letter.In effect,the White House claimed that it could invalidate any otherwise legitimate state law that it disagrees with.Some powers do belong exclusively to the federal government,and control of citizenship and the borders is among them.But if Congress wanted to prevent states from using their own resources to check immigration status,it could.It never did so.The administration was in essence asserting that because it didn’t want to carry out Congress’s immigration wishes,no state should be allowed to do so either.Every Justice rightly rejected this remarkable claim.36.Three provisions of Arizona’s plan were overturned because they[A]deprived the federal police of Constitutional powers.[B]disturbed the power balance between different states.[C]overstepped the authority of federal immigration law.[D]contradicted both the federal and state policies.37.On which of the following did the Justices agree,according to Paragraph4?[A]Federal officers’duty to withhold immigrants’information.[B]States’independence from federal immigration law.[C]States’legitimate role in immigration enforcement.[D]Congress’s intervention in immigration enforcement.38.It can be inferred from Paragraph5that the Alien and Sedition Acts[A]violated the Constitution.[B]undermined the states’interests.[C]supported the federal statute.[D]stood in favor of the states.39.The White House claims that its power of enforcement[A]outweighs that held by the states.[B]is dependent on the states’support.[C]is established by federal statutes.[D]rarely goes against state laws.40.What can be learned from the last paragraph?[A]Immigration issues are usually decided by Congress.[B]Justices intended to check the power of the Administrstion.[C]Justices wanted to strengthen its coordination with Congress.[D]The Administration is dominant over immigration issues.Part BDirections:In the following article,some sentences have been removed.For Questions41-45,choose the most suitable one from the list A-G to fit into each of the numbered blank.There are two extra choices, which do not fit in any of the gaps.Mark your answers on ANSWER SHEET1.(10points)The social sciences are flourishing.As of2005,there were almost half a million professional social scientists from all fields in the world,working both inside and outside academia.According to the World Social Science Report2010,the number of social-science students worldwide has swollen by about11%every year since2000.Yet this enormous resource in not contributing enough to today’s global challenges including climate change,security,sustainable development and health.(41)______Humanity has the necessary agro-technological tools to eradicate hunger,from genetically engineered crops to arificial fertilizers. Here,too,the problems are social:the organization and distribution of food,wealth and prosperity.(42)____This is a shame—the community should be grasping the opportunity to raise its influence in the real world.To paraphrase the great social scientist Joseph Schumpeter:there is no radical innovation without creative destruction.Today,the social sciences are largely focused on disciplinary problems and internal scholarly debates,rather than on topics with external impact.Analyses reveal that the number of papers including the keywords“environmental changed”or “climate change”have increased rapidly since2004,(43)____When social scientists do tackle practical issues,their scope is often local:Belgium is interested mainly in the effects of poverty on Belgium for example.And whether the community’s work contributes much to an overall accumulation of knowledge is doubtful.The problem is not necessarily the amount of available funding(44)____this is an adequate amount so long as it is aimed in the right direction.Social scientists who complain about a lack of funding should not expect more in today’s economic climate.The trick is to direct these funds better.The European Union Framework funding programs have long had a category specifically targeted at social scientists.This year,it was proposed that system be changed:Horizon2020,a new program to be enacted in2014,would not have such a category,This has resulted in protests from social scientists.But the intention is not to neglect social science;rather,the complete opposite.(45)____That should create more collaborative endeavors and help to develop projects aimed directly at solving global problems.[A]It could be that we are evolving two communities of social scientists:one that is discipline-oriented and publishing in highly specialized journals,and one that is problem-oriented and publishing elsewhere,such as policy briefs.[B]However,the numbers are still small:in2010,about1,600of the100,000social-sciences papers published globally included one of these Keywords.[C]the idea is to force social to integrate their work with other categories,including health and demographic change food security,marine research and the bio-economy,clear,efficient energy;and inclusive,innovative and secure societies.[D]the solution is to change the mindset of the academic community,and what it considers to be its main goal.Global challenges and social innovation ought to receive much more attention from scientists,especially the young ones.[E]These issues all have root causes in human behavior.all require behavioral change and social innovations,as well as technological development.Stemming climate change,for example,is as much about changing consumption patterns and promoting tax acceptance as it is about developing clean energy.[F]Despite these factors,many social scientists seem reluctant to tackle such problems.And in Europe,some are up in arms over a proposal to drop a specific funding category for social-science research and to integrate it within cross-cutting topics of sustainable development.[G]During the late1990s,national spending on social sciences and the humanities as a percentage of all research and development funds-including government,higher education,non-profit and corporate-varied from around4%to25%;in most European nations,it is about15%.Part

then translate the underlined segments into Chinese.Your translation should be written clearly on ANSWER SHEET2.(10points)It is speculated that gardens arise from a basic need in the individuals who made them:the need for creative expression.There is no doubt that gardens evidence an impossible urge to create,express, fashion,and beautify and that self-expression is a basic human urge;(46)Yet when one looks at the photographs of the garden created by the homeless,it strikes one that,for all their diversity of styles, these gardens speak os various other fundamental urges,beyond that of decoration and creative expression.One of these urges had to do with creating a state of peace in the midst of turbulence,a“still point of the turning world,”to borrow a phrase from T.S.Eliot.(47)A sacred place of peace,however crudeit may be,is a distinctly human need,as opposed to shelter,which is a distinctly animal need.This distinction is so much so that where the latter is lacking,as it is for these unlikely gardens,the foemer becomes all the more posure is a state of mind made possible by the structuring of one’s relation to one’s environment.(48)The gardens of the homeless which are in effect homeless gardens introduce from into an urban environment where it either didn’t exist or was not discernible as such.In so doing they give composure to a segment of the inarticulate environment in which they take their stand.Another urge or need that these gardens appear to respond to,or to arise from is so intrinsic that we are barely ever conscious of its abiding claims on us.When we are deprived of green,of plants,of trees,(49)most of us give into a demoralization of spirit which we usually blame on some psychological conditions,until one day we find ourselves in garden and feel the expression vanish as if by magic.In most of the homeless gardens of New York City the actual cultivation of plants is unfeasible,yet even so the compositions often seem to represent attempts to call arrangement of materials,an institution of colors,small pool of water,and a frequent presence of petals or leaves as well as of stuffed animals.On display here are various fantasy elements whose reference,at some basic level,seems to be the natural world.(50)It is this implicit or explicit reference to nature that fully justifies the use of word garden though in a“liberated”sense,to describe these synthetic constructions. In them we can see biophilia-a yearning for contact with nonhuman life-assuming uncanny representational forms.Section III WritingParty A51Directions:Write an e-mail of about100words to a foreign

选项transmit“传输，发射”，也不能与ability搭配，D选项deliver“传递”，同样不能与ability搭配.A,C,D无论从搭配上还是意思上都不合适.A选项grant本身具有赋予，授予的意思.故答案选A.2.【答案】D【解析】external外部因素和上文的backgroundinformation同义复现，不考虑背景信息，不受外界因素影响.A选项minor次要的，B选项objective客观的，C选项crucial残酷的，D选项external 外部的，故答案选D.3.【答案】C【解析】第三题本句but引起句意转折.“但是XX推测不考虑大局会导致决策者被日常接触的信息影响而带有偏见.”首先注意到空前面有定冠词the医学全在线，指代上文信息，即不考虑背景信息、不考虑大环境.而大局，大环境的表达，此处选择picture是最贴切的.A 选项issue问题，B选项vision想象力，美景都不合适，故答案选C.4.【答案】A【解析】通读后面的句子，提到了法官与被告，这明显是生活当中的一个具体的实例，故答案选A.而B选项on average“平均，通常”，出现的话，周围往往应该要出现数字.C选项in principle “大体上，原则上”，后面需要出现的是总结性的话语，D选项above all“首先”是用来列举条目，将A,B,D排除.5.【答案】B【解析】从句意上来看“例如，他们提出理论，认为法官不敢在罪行面前表现得太软弱，如果当天已经宣判五六名被告执行缓刑，那么他很有可能将下一个人送入监狱.A选项fond of喜欢，B 选项fear of惧怕，C选项capable of有能力，D选项thoughtless of考虑不周，故答案选B.6.【答案】B【解析】根据句内的逻辑关系，在对待犯罪行为方面害怕表现出太软弱，在...方面，关于...的表达应该用介词on，故答案为B.7.【答案】A【解析】A if表条件.B选项until表时间，往往跟not连用，直接排除.C选项though表让步，D 选项unless相当于if...not.通读空格所在的前后句子，得出这两句之间的逻辑关系是表示条件的.8.【答案】D【解析】首先注意到idea前面有定冠词this，很明显指代上文提出的观点.而且跟上文以法官为例一样，下文“他们把注意力转向大学录取过程”也是上文观点的例证，目的是对上文的观点进行检验，而不是A选项“促进”，B选项“强调”或C选项“分享”，故答案选D.9.【答案】D【解析】A选项decision“决定”，B选项quality“质量，品质”，C选项status“地位”，D选项success“成功”.申请者的____不应该取决于同一天随机选到的其他几名申请者.接着下文讲到面试官面试MBA[微博]申请者的结果results，因此第9题应该也有结果的意思，与下文结合是达到正面的结果，因此答案是即“申请者的成功”.其它选项带入原文重叠答案，与原义不符合10.【答案】A【解析】空格后面有一个副词为randomly，随机地，既然是随机，那么选项B选项studied“研究过的”，C选项found“找到的”D选项identified“经鉴定的”就与randomly是相矛盾的，全部排除.11.【答案】D【解析】本题解题关键在于but，通过suspect可以看出Dr.Simonsohn与前文意思相反，因此otherwise正好符合题意.12.【答案】C【解析】此外明显缺一个过去分词作interviews的定语，再看by后面的officers，只有conducted(执行)，符合语境，故为正确答案.13.【答案】B【解析】本题末尾one to five(从一到五)，前面又有一个on a scale(…的范围)，A分配，D排列语义上说不通，再综合后面的factor(因素)，对比一下，只有B(划分等级)，整合起来，即划分成一到五个等级，合情合理C match看似与to搭配，但也不符合文意，故正确答案为B.14.【答案】D【解析】本题需联系整句话，take…into consideration(考虑，涉及)，从形式上来说没有问题，再从意义上来看，说“这个等级考虑了几种因素…”，是对上文评级的进一步解释，也没有问题.15.【答案】B【解析】还是承接上文讲到的评级得分，后半句讲到的是(平时学校等级)考试得分，再结合中间conjunction一词(联接)，可以推断为then(具有承接之意)，因此为正确答案，而A和D为同一意义和用法(代替)，与conjunction相冲突，C说不通，故也为错误选项.16.【答案】C【解析】本题出在一个非限定性定语从句上，先行词为a standardized exam,后半句是800分，考试和分数之间首选marked，选项B通过具有一定的干扰性，但注意主语是考试，所以正确选项为C.A为无关选项.17.【答案】A【解析】本句属于比较级，对比的是几个面试者的分数，C、D是空间上的上下，而这里缺的时间上的先后，故排除C和D，B是“之后”，不符合语言先后逻辑，故正确答案为A.18.【答案】C【解析】解本题需往下看，to…the effects of such adecrease,由此可以判断接下来那个应聘者的分数是出现了下降，故直击正确选项C.19.【答案】B【解析】该句为不定式作主语，“(面试考官可能给)更低的分数”所带来的影响，可以推断，是消除或是抵消这种不利结果，应聘者需要在GMAT[微博]中多拿30分，A“达到”，C“保持”D“漠视”明显不符，故A“消除”为正确答案.20.【答案】C【解析】该题难度较大，需把句意弄懂，也就是“这30分是比…所多的”建议把四个选项分别代入空格处，A有前途的，B可能的，C必须的，D有帮助的，对比之后，只有C最合逻辑，也就是说“这30分是比原本该考试所必须要求的多出来的，即另外多拿本不需要的30分才能平衡前面的更低的分数”，故C为正确选项.Section II Reading ComprehensionPart AText121.【答案】B(insensitivity to fashion)【解析】事实细节题.根据题干，首先定位到首段.由文章第一句后半句“…scoldsher unattractive assistant for imagining that high fashion doesn’t affect her.”意思是：“……批评她没有魅力的助理，因为助理认为高级时尚对她的生活影响不大”.可知criticize是对scolds的同义替换，B项中的“insensitivity to fashion”是“imagining that high fashion doesn’t affect her.”的同义替换.所以B项为正确答案.A项在文中并未提及，属于无中生有.C项和D项是对文章第一句的曲解.22.【答案】D(shop for their garments more frequently)【解析】事实细节题.根据题干，首先定位到第二段.由倒数第二句“these labels encouragestyle-conscious consumers to see clothes as disposable,……,and to renew their wardrobeevery few weeks.”意思是“这些商标(畅销商标)促使有时尚意识的消费者将服装看成是用完就可以丢弃的，……，并且每周更新他们的衣橱.”D选项“shop for their garments morefrequently”的意思是医学全在线“更加频繁地购买服装”，正好是“renew their wardrobe every few weeks”的同义替换.A，B，C项均属于无中生有项.23.【答案】A(accusation)【解析】词义题.题干中需要猜测词义的单词出现在第二段的第一句“……thefeverish world described in Overdressed,Elizabeth Cline’s three-year indictment of‘fast fashion’”.再结合选项可知，“indictment”是ElizabethCline对“快时尚”的一种态度.因此，解答此题的关键在于联系上下文语境，找到Elizabeth Cline对“快时尚”的态度.由第二段最后一句“By offering on-trend items at dirt-cheap prices,Cline argues,thesebrands have hijacked fashion cycles,shaking an industry long accustomed to aseasonal pace.”，意思是“Cline说，通过以特别低的价格销售潮流物品，这些品牌破坏了潮流周期，动摇了这个长久以来习惯于季节周期的产业”.由“hijack”和“shaking”可知，Cline对“快时尚”应该是持否定态度的，所以选项A“accusation(谴责)”是正确选项.24.【答案】D(pricing is vital to environmental-friendlypurchasing)【解析】推理判断题.根据题干，可定位到最后一段.解题关键在于“Vanity is a constant;peoplewill only start shopping more sustainably when they can’t afford not to”，意思是“每个人都很虚荣，这很常见.但消费者付不起太多东西的时候，他们才会以更加可持续的方式去购物.”这句的关键词是“afford”和“shopmore sustainably”，对应于D项中的“pricing”和“environmental-friendly purchasing”.A项对于本段的曲解.B项说的是“忽视环境的可持续发展”，与文中“severalfast-fashion companies have made efforts to curb their impact on labor and theenvironment…”(一些时尚服饰公司已经做出努力减少对劳动力和环境)意思相悖.C项文中未提及.25.【答案】C(criticism of thefast-fashion industry)【解析】主旨大意题.此题考查对全文主旨大意的准确归纳.从整个文章脉络来看，文章的第一段用事例引入，第二段讲到文章的主题“快时尚”，并指出它破坏了时尚周期，动摇了时尚产业.第三四段指出“快时尚”这种变革的弊端，比如：给自然资源造成压力、使用大量有害的化学物质、浪费现象.最后两段提到针对“快时尚”的不良影响，可以采取的解决办法.由此可知，C 项统领全文，为正确答案.A,B,D项都不是文章所论述的中心主题.Text2。

21．标准答案：B
考点分析：此题为事实细节题。根据题干，首先定位到首段。由文章第一句后半句“…scolds her unattractive assistant for imagining that highfashiondoesn’t affect her.”意思是：“……批评她没有魅力的助理，因为助理认为高级时尚对她的生活影响不大”。可知criticize是对scolds的同义替换，B项中的“insensitivity to fashion”是“imagining that high fashion doesn’t affect her.”的同义替换。所以B项为正确答案。

Mark your answers on ANSWER SHEET 1. (40 points)Text 1In the 2006 film version of The Devil Wears Prada, Miranda Priestly, played by Meryl Streep, scolds her unattractive assistant for imagining that high fashion doesn‘t affect her, Priestly explains how the deep blue color of the assistant‘s sweater descended over the years from fashion shows to departments stores and to the bargain bin in which the poor girl doubtless found her garment.This top-down conception of the fashion business couldn‘t be more out of date or at odds with the feverish would be described in Overdressed, Elizabeth Cline‘s three-year indictment of ―fast fashion‖. In the last decade or so, advances in technology have allowed mass-market labels such as Zara, H&M, and Uniqlo to react to trends more quickly and anticipate demand more precisely. Quicker turnarounds mean less wasted inventory, more frequent release, and more profit. These labels encourage style-conscious consumers to see clothes as disposable-meant to last only a wash or two, although they don‘t advertise that –and to renew their wardrobe every few weeks. By offering on-trend items at dirt-cheap prices, Cline argues, these brands have hijacked fashion cycles, shaking an industry long accustomed to a seasonal pace.The victims of this revolution, of course, are not limited to designers. For H&M to offer a $5.95 knit miniskirt in all its 2,300-pius stores around the world, it must rely on low-wage overseas labor, order in volumes that strain natural resources, and use massive amounts of harmful chemicals.Overdressed is the fashion world‘s answer to consumer-activist bestsellers like Michael Pollan‘s T he Omnivore‘s Dilemma. ―Mass-produced clothing, like fast food, fills a hunger and need, yet is non-durable and wasteful,‖ Cline argues. Americans, she finds, buy roughly 20 billion garments a year –about 64 items per person – and no matter how much they give away, this excess leads to waste.Towards the end of Overdressed, Cline introduced her ideal, a Brooklyn woman named Sarah Kate Beaumont, who since 2008 has made all of her own clothes – and beautifully. But as Cline is the first to note, it took Beau mont decades to perfect her craft; her example can‘t be knocked off.Though several fast-fashion companies have made efforts to curb their impact on labor and the environment – including H&M, with its green Conscious Collection line –Cline believes lasting change can only be effected by the customer. She exhibits the idealism common to many advocates of sustainability, be it in food or in energy. Vanity is a constant; people will only start shopping more sustainably when they can‘t afford not to.21. Priestly criticizes her assistant for her[A] poor bargaining skill.[B] insensitivity to fashion.[C] obsession with high fashion.[D] lack of imagination.22. According to Cline, mass-market labels urge consumers to[A] combat unnecessary waste.[B] shut out the feverish fashion world.[C] resist the influence of advertisements.[D] shop for their garments more frequently.23. The word ―indictment‖ (Line 3, Para.2) is close st inmeaning to[A] accusation.[B] enthusiasm.[C] indifference.[D] tolerance.24. Which of the following can be inferred from the last paragraph?[A] Vanity has more often been found in idealists.[B] The fast-fashion industry ignores sustainability.[C] People are more interested in unaffordable garments.[D] Pricing is vital to environment-friendly purchasing.25. What is the subject of the text?[A] Satire on an extravagant lifestyle.[B] Challenge to a high-fashion myth.[C] Criticism of the fast-fashion industry.[D] Exposure of a mass-market secret.Text 2An old saying has it that half of all advertising budgets are wasted-the trouble is, no one knows which half. In the internet age, at least in theory, this fraction can be much reduced. By watching what people search for, click on and say online, companies can aim ―behavioural‖ ads a t those most likely to buy.In the past couple of weeks a quarrel has illustrated the value to advertisers of such fine-grained information: Should advertisers assume that people are happy to be tracked and sent behavioural ads? Or should they have explicit permission?In December 2010 America's Federal Trade Commission (FTC) proposed adding a "do not track "(DNT) option to internet browsers ,so that users could tell advertisers that they did not want to befollowed .Microsoft's Internet Explorer and Apple's Safari both offer DNT ;Google's Chrome is due to do so this year. In February the FTC and Digital Advertising Alliance (DAA) agreed that the industry would get cracking on responding to DNT requests.On May 31st Microsoft Set off the row: It said that Internet Explorer 10, the version due to appear windows 8, would have DNT as a default.It is not yet clear how advertisers will respond. Getting a DNT signal does not oblige anyone to stop tracking, although some companies have promised to do so. Unable to tell whether someone really objects to behavioural ads or whether they are sticking with Microsoft‘s default, some may ignore a DNT signal and press on anyway.Also unclear is why Microsoft has gone it alone. After all, it has an ad business too, which it says will comply with DNT requests, though it is still working out how. If it is trying to upset Google, which relies almost wholly on default will become the norm. DNT does not seem an obviously huge selling point for windows 8-though the firm has compared some of its other products favourably with Google's on that count before. Brendon Lynch, Microsoft's chief privacy officer, blogged: "we believe consumers should have more control." Could it really be that simple?26. It is suggested in paragraph 1 that ―behavioural‖ ads help advertisers to:[A] ease competition among themselves[B] lower their operational costs[C] avoid complaints from consumers[D] provide better online services27. ―The industry‖ (Line 6,Para.3) refers to:[A] online advertisers[B] e-commerce conductors[C] digital information analysis[D] internet browser developers28. Bob Liodice holds that setting DNT as a default[A] many cut the number of junk ads[B] fails to affect the ad industry[C] will not benefit consumers[D] goes against human nature29. Which of the following is true according to Paragraph.6?[A] DNT may not serve its intended purpose[B] Advertisers are willing to implement DNT[C] DNT is losing its popularity among consumers[D] Advertisers are obliged to offer behavioural ads30. The author's attitude towards what Brendon Lynch said in his blog is one of:[A] indulgence[B] understanding[C] appreciation[D] skepticismText 3Up until a few decades ago, our visions of the future were largely - though by no means uniformly - glowingly positive. Science and technology would cure all the ills of humanity, leading to lives of fulfillment and opportunity for all.Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change. You might even be tempted to assume that humanity has little future to lookforward to.But such gloominess is misplaced. The fossil record shows that many species have endured for millions of years - so why shouldn't we? Take a broader look at our species' place in the universe, and it becomes clear that we have an excellent chance of surviving for tens, if not hundreds, of thousands of years. Look up Homo sapiens in the "Red List" of threatened species of the International Union for the Conversation of Nature (IUCN) ,and you will read: "Listed as Least Concern as the species is very widely distributed, adaptable, currently increasing, and there are no major threats resulting in an overall population decline."So what does our deep future hold? A growing number of researchers and organizations are now thinking seriously about that question. For example, the Long Now Foundation has its flagship project a medical clock that is designed to still be marking time thousands of years hence.Perhaps willfully, it may be easier to think about such lengthy timescales than about the more immediate future. The potential evolution of today's technology, and its social consequences, is dazzlingly complicated, and it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage. That's one reason why we have launched Arc, a new publication dedicated to the near future.But take a longer view and there is a surprising amount that we can say with considerable assurance. As so often, the past holds the key to the future: we have now identified enough of the long-term patterns shaping the history of the planet, and our species, to make evidence-based forecasts about the situations in which our descendants will find themselves.This long perspective makes the pessimistic view of ourprospects seem more likely to be a passing fad. To be sure, the future is not all rosy. But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans, and to improve the lot of those to come.31. Our vision of the future used to be inspired by[A] our desire for lives of fulfillment[B] our faith in science and technology[C] our awareness of potential risks[D] our belief in equal opportunity32. The IUCN‘s ―Red List‖ suggest that human being are[A] a sustained species[B] a threaten to the environment[C] the world‘s dominant power[D] a misplaced race33. Which of the following is true according to Paragraph 5?[A] Arc helps limit the scope of futurological studies.[B] Technology offers solutions to social problem.[C] The interest in science fiction is on the rise.[D] Our Immediate future is hard to conceive.34. To ensure the future of mankind, it is crucial to[A] explore our planet‘s abundant resources[B] adopt an optimistic view of the world[C] draw on our experience from the past[D] curb our ambition to reshape history35. Which of the following would be the best title for the text?[A] Uncertainty about Our Future[B] Evolution of the Human Species[C] The Ever-bright Prospects of Mankind[D] Science, Technology and HumanityText 4On a five to three vote, the Supreme Court knocked out much of Arizona‘s immigration law Monday-a modest policy victory for the Obama Administration. But on the more important matter of the Constitution, the decision was an 8-0 defeat for the Administration‘s effort to upset the balance of power between the federal government and the states.In Arizona v. U nited States, the majority overturned three of the four contested provisions of Arizona‘s controversial plan to have state and local police enforce federal immigration law. The Constitutional principles that Washington alone has the power to ―establish a uniform Rule of Naturalization ‖and that federal laws precede state laws are noncontroversial . Arizona had attempted to fashion state policies that ran parallel to the existing federal ones.Justice Anthony Kennedy, joined by Chief Justice John Roberts and the Court‘s liberals, ruled that the state flew too close to the federal sun. On the overturned provisions the majority held the congress had deliberately ―occupied the field‖ and Arizona had thus intruded on the federal‘s privileged powers.However, the Justices said that Arizona police would be allowed to verify the legal status of people who come in contact with law enforcement. That‘s because Congress has alwa ys envisioned jointfederal-state immigration enforcement and explicitly encourages state officers to share information and cooperate with federal colleagues.Two of the three objecting Justice-Samuel Alito and Clarence Thomas-agreed with this Constitutional logic but disagreed about which Arizona rules conflicted with the federal statute. Theonly major objection came from Justice Antonin Scalia, who offered an even more robust defense of state privileges going back to the Alien and Sedition Acts.The 8-0 objection to President Obama turns on what Justice Samuel Alito describes in his objection as ―a shocking assertion of federal executive power‖. The White House argued that Arizona‘s laws conflicted with its enforcement priorities, even if state laws complied with federal statutes to the letter. In effect, the White House claimed that it could invalidate any otherwise legitimate state law that it disagrees with.Some powers do belong exclusively to the federal government, and control of citizenship and the borders is among them. But if Congress wanted to prevent states from using their own resources to check immigration status, it could. It never did so. The administration was in essence asserting that because it didn‘t want to carry out Congress‘s immigrati on wishes, no state should be allowed to do so either. Every Justice rightly rejected this remarkable claim.36. Three provisions of Arizona‘s plan were overturned because they[A] deprived the federal police of Constitutional powers.[B] disturbed the power balance between different states.[C] overstepped the authority of federal immigration law.[D] contradicted both the federal and state policies.37. On which of the following did the Justices agree, according to Paragraph4?[A] Federal officers‘ duty t o withhold immigrants ?information.[B] States‘ independence from federal immigration law.[C] States‘ legitimate role in immigration enforcement.[D] Congress‘s intervention in immigration enforcement.38. It can be inferred from Paragraph 5 that the Alien and Sedition Acts[A] violated the Constitution.[B] undermined the states‘ interests.[C] supported the federal statute.[D] stood in favor of the states.39. The White House claims that its power of enforcement[A] outweighs that held by the states.[B] is dependent on the states‘ support.[C] is established by federal statutes.[D] rarely goes against state laws.40. What can be learned from the last paragraph?[A] Immigration issues are usually decided by Congress.[B] Justices intended to check the power of the Administration.[C] Justices wanted to strengthen its coordination with Congress.[D] The Administration is dominant over immigration issues.Part BDirections:In the following article, some sentences have been removed.

Mark your answers on ANSWER SHEET 1. (10 points)The social sciences are flourishing. As of 2005, there were almost half a million professional social scientists from all fields in the world, working both inside and outside academia. According to the World Social Science Report 2010, the numberof social-science students worldwide has swollen by about 11% every year since 2000.Yet this enormous resource in not contributing enough to today‘s global ch allenges including climate change, security, sustainable development and health.(41)______Humanity has the necessaryagro-technological tools to eradicate hunger, from genetically engineered crops to artificial fertilizers . Here, too, the problems are social: the organization and distribution of food, wealth and prosperity.(42)____This is a shame—the community should be grasping the opportunity to raise its influence in the real world. To paraphrase the great social scientist Joseph Schumpeter: there is no radical innovation without creative destruction.Today, the social sciences are largely focused on disciplinary problems and internal scholarly debates, rather than on topics with external impact.Analyses reveal that the number of papers including the k eywords ―environmental changed‖ or ―climate change‖ have increased rapidly since 2004,(43)____When social scientists do tackle practical issues ,their scope is often local: Belgium is interested mainly in the effects of poverty on Belgium for example .And whether the community‘s work contributes much to an overall accumulation of knowledge is doubtful.The problem is not necessarily the amount of available funding (44)____this is an adequate amount so long as it is aimed in the right direction. Social scientists who complain about a lack of funding should not expect more in today‘s economic climate.The trick is to direct these funds better. The European UnionFramework funding programs have long had a category specifically targeted at social scientists. This year, it was proposed that system be changed: Horizon 2020,a new program to be enacted in 2014,would not have such a category ,This has resulted in protests from social scientists. But the intention is not to neglect social science; rather, the complete opposite.(45)____That should create more collaborative endeavors and help to develop projects aimed directly at solving global problems.[A] It could be that we are evolving two communities of social scientists: one that is discipline-oriented and publishing in highly specialized journals, and one that is problem-oriented and publishing elsewhere, such as policy briefs.[B] However, the numbers are still small: in 2010, about 1,600 of the 100,000 social-sciences papers published globally included one of these Keywords.[C] the idea is to force social to integrate their work with other categories, including health and demographic change food security, marine research and the bio-economy, clear, efficient energy; and inclusive, innovative and secure societies.[D] the solution is to change the mindset of the academic community, and what it considers to be its main goal. Global challenges and social innovation ought to receive much more attention from scientists, especially the young ones.[E] These issues all have root causes in human behavior. All require behavioral change and social innovations, as well as technological development. Stemming climate change, for example, is as muchabout changing consumption patterns and promoting tax acceptance as it is about developing clean energy.[F] Despite these factors, many social scientists seem reluctant to tackle such problems. And in Europe, some are up in arms over a proposal to drop a specific funding category for social-science research and to integrate it within cross-cutting topics of sustainable development.[G]During the late 1990s , national spending on social sciences and the humanities as a percentage of all research and development funds-including government, higher education, non-profit and corporate-varied from around 4% to 25%; in most European nations , it is about 15%.Section III Translation46.

There is no doubt that gardens evidence an impossible urge to create, express, fashion, and beautify and that self-expression is a basic human urge; (46) Yet when one looks at the photographs of the garden created by the homeless, it strikes one that , for all their diversity of styles, these gardens speak of various other fundamental urges, beyond that of decoration and creative expression.One of these urges had to do with creating a state of peace in the midst of turbulence, a ―still point of the turning world,‖ t o borrow a phrase from T. S. Eliot. (47)A sacred place of peace, however crude it may be, is a distinctly human need, as opposed to shelter, which is a distinctly animal need. This distinction is somuch so that where the latter is lacking, as it is for these unlikely gardens, the former becomes all the more urgent. Composure is a state of mind made possib le by the structuring of one‘s relation to one‘s environment. (48) The gardens of the homeless which are in effect homeless gardens introduce from into an urban environment where it either didn‘t exist or was not discernible as such. In so doing they give composure to a segment of the inarticulate environment in which they take their stand.Another urge or need that these gardens appear to respond to, or to arise from is so intrinsic that we are barely ever conscious of its abiding claims on us. When we are deprived of green, of plants, of trees, (49) most of us give into a demoralization of spirit which we usually blame on some psychological conditions, until one day we find ourselves in garden and feel the expression vanish as if by magic. In most of the homeless gardens of New York City the actual cultivation of plants is unfeasible, yet even so the compositions often seem to represent attempts to call arrangement of materials, an institution of colors, small pool of water, and a frequent presence of petals or leaves as well as of stuffed animals. On display here are various fantasy elements whose reference, at some basic level, seems to be the natural world.(50)It is this implicit or explicit reference to nature that fully justifies the use of word garden though in a ―liberated‖ sense, to describe these synthetic constructions. In them we can see biophilia- a yearning for contact with nonhuman life－assuming uncanny representational forms.Section IV WritingPart A51.

electronic money,you might think that we would move quickly to the cashless society in which all payments are made electronically.1 a true cashless society is probably not around the corner.Indeed,predictions have been2for two decades but have not yet come to fruition.For example,Business Week predicted in1975that electronic means of payment would soon"revolutionize the very3of

choosing A,B,C or D.Mark your answers on ANSWER SHEET 1.(40points) Text1In an essay entitled“Making It in America”,the author Adam Davidson relates a joke from cotton about just how much a modern textile mill has been automated: The average mill only two employees today,”a man and a dog.The man is there to feed the dog is there to keep the man away from the machines.”Davidson’s article is one of a number of pieces that have recently appeared making the point that the reason we have such stubbornly high unemployment and declining middle-class incomes today is also because of the advances in both globalization and the information technology revolution,which are more rapidly than ever replacing labor with machines or foreign worker.In the past,workers with average skills,doing an average job，could earn an average lifestyle,But,today,average is officially over.Being average just won’t earn you what it used to.It can’t when so many more employers have so much more access to so much more above average cheap foreign labor,cheap robotics,cheap software,cheap automation and cheap genius.Therefore,everyone needs to find their extra-their unique value contribution that makes them stand out in whatever is their field of employment.Yes,new technology has been eating jobs forever,and always will.But there’s been an acceleration.As Davidson notes,”In the10years ending in2009,[U.S.] factories shed workers so fast that they erased almost all the gains of the previous 70years;roughly one out of every three manufacturing jobs-about6million in total -disappeared.There will always be changed-new jobs,new products,new services.But the one thing we know for sure is that with each advance in globalization and the I.T. revolution,the best jobs will require workers to have more and better education to make themselves above average.In a world where average is officially over,there are many things we need to do to support employment,but nothing would be more important than passing some kind of G.I.Bill for the21st century that ensures that every American has access to poet-high school education.21.The joke in Paragraph1is used to illustrate_______[A]the impact of technological advances[B]the alleviation of job pressure[C]the shrinkage of textile mills[D]the decline of middle-class incomes22.According to Paragraph3,to be a successful employee,one has to______[A]work on cheap software[B]ask for a moderate salary[C]adopt an average lifestyle[D]contribute something unique23.The quotation in Paragraph4explains that______[A]gains of technology have been erased[B]job opportunities are disappearing at a high speed[C]factories are making much less money than before[D]new jobs and services have been offered24.According to the author,to reduce unemployment,the most important is_____[A]to accelerate the I.T.revolution[B]to ensure more education for people[C]ro advance economic globalization[D]to pass more bills in the21st century25.Which of the following would be the most appropriate title for the text?[A]New Law Takes Effect[B]Technology Goes Cheap[C]Average Is Over[D]Recession Is BadText2A century ago,the immigrants from across the Atlantic inclued settlers and sojourners.Along with the many folks looking to make a permanent home in the United States came those who had no intention to stay,and7millin people arrived while about2million departed.About a quarter of all Italian immigrants,for exanmle, eventually returned to Italy for good.They even had an affectionate nickname,“uccelli di passaggio,”birds of passage.Today,we are much more rigid about immigrants.We divide nemcomers into two categories:legal or illegal,good or bad.We hail them as Americans in the making, or our broken immigrantion system and the long political paralysis over how to fix it.We don’t need more categories,but we need to change the way we think about categories.We need to look beyond strick definitions of legal and illegal.To start, we can recognize the new birds of passage,those living and thriving in the gray areas.We might then begin to solve our immigration challenges.Crop pickers,violinists,construction workers,entrepreneurs,engineers,home health-care aides and physicists are among today’s birds of passage.They are energetic participants in a global economy driven by the flow of work,money and ideas.They prefer to come and go as opportunity calls them,They can manage to have a job in one place and a family in another.With or without permission,they straddle laws,jurisdictions and identities with ease.We need them to imagine the United States as a place where they can beproductive for a while without committing themselves to staying forever.We need them to feel that home can be both here and there and that they can belong to two nations honorably.Accommodating this new world of people in motion will require new attitudes on both sides of the immigration battle.Looking beyond the culture war logic of right or wrong means opening up the middle ground and understanding that managing immigration today requires multiple paths and multiple outcomes.Including some that are not easy to accomplish legally in the existing system.26“Birds of passage”refers to those who____[A]immigrate across the Atlantic.[B]leave their home countries for good.[C]stay in a foregin temporaily.[D]find permanent jobs overseas.27It is implied in paragraph2that the current immigration stystem in the US____[A]needs new immigrant categories.[B]has loosened control over immigrants.[C]should be adopted to meet challenges.[D]has been fixeed via political means.28According to the author,today’s birds of passage want___[A]fiancial incentives.[B]a global recognition.[C]opportunities to get regular jobs.[D]the freedom to stay and leave.29The author suggests that the birds of passage today should be treated__[A]as faithful partners.[B]with economic favors.[C]with legal tolerance.[D]as mighty rivals.30which of the best title for the passage?[A]come and go:big mistake.[B]living and thriving:great risk.[C]with or without:great risk.[D]legal or illegal:big mistake.Text3Scientists have found that although we are prone to snap overreactions,if we take a moment and think about how we are likely to react,we can reduce or even eliminate the negative effects of our quick,hard-wired responses.Snap decisions can be important defense mechanisms;if we are judging whether someone is dangerous,our brains and bodies are hard-wired to react very quickly, within milliseconds.But we need more time to assess other factors.To accurately tell whether someone is sociable,studies show,we need at least a minute,preferably five.It takes a while to judge complex aspects of personality,like neuroticism or open-mindedness.But snap decisions in reaction to rapid stimuli aren’t exclusive to the interpersonal realm.Psychologists at the University of Toronto found that viewing a fast-food logo for just a few milliseconds primes us to read20percent faster, even though reading has little to do with eating.We unconsciously associate fast food with speed and impatience and carry those impulses into whatever else we’re doing,Subjects exposed to fast-food flashes also tend to think a musical piece lasts too long.Yet we can reverse such influences.If we know we will overreact to consumer products or housing options when we see a happy face(one reason good sales representatives and real estate agents are always smiling),we can take a moment before buying.If we know female job screeners are more likely to reject attractive female applicants,we can help screeners understand their biases-or hire outside screeners.John Gottman,the marriage expert,explains that we quickly“thin slice”information reliably only after we ground such snap reactions in“thick sliced”long-term study.When Dr.Gottman really wants to assess whether a couple will stay together,he invites them to his island retreat for a muck longer evaluation;two days,not two seconds.Our ability to mute our hard-wired reactions by pausing is what differentiates us from animals:doge can think about the future only intermittently or for a few minutes.But historically we have spent about12percent of our days contemplating the longer term.Although technology might change the way we react,it hasn’t changed our nature.We still have the imaginative capacity to rise above temptation and reverse the high-speed trend.31.The time needed in making decisions may____.[A]vary according to the urgency of the situation[B]prove the complexity of our brain reaction[C]depend on the importance of the assessment[D]predetermine the accuracy of our judgment32.Our reaction to a fast-food logo shows that snap decisions____.[A]can be associative[B]are not unconscious[C]can be dangerous[D]are not impulsive33.To reverse the negative influences of snap decisions,we should____.[A]trust our first impression[B]do as people usually do[C]think before we act[D]ask for expert advice34.John Gottman says that reliable snap reaction are based on____.[A]critical assessment[B]‘‘thin sliced’’study[C]sensible explanation[D]adequate information35.The author’s attitude toward reversing the high-speed trend is____.[A]tolerant[B]uncertain[C]optimistic[D]doubtfulText4Europe is not a gender-equality heaven.In particular,the corporate workplace will never be completely family—friendly until women are part of senior management decisions,and Europe’s top corporate-governance positions remain overwhelmingly male.indeed,women hold only14percent of positions on Europe corporate boards.The Europe Union is now considering legislation to compel corporate boards to maintain a certain proportion of women-up to60percent.This proposed mandate was born of st year,Europe Commission Vice President Viviane Reding issued a call to voluntary action.Reding invited corporations to sign up for gender balance goal of40percent female board membership.But her appeal was considered a failure:only24companies took it up.Do we need quotas to ensure that women can continue to climb the corporate Ladder fairy as they balance work and family?“Personally,I don’t like quotas,”Reding said recently.“But i like what the quotas do.”Quotas get action:they“open the way to equality and they break through the glass ceiling,”according to Reding,a result seen in France and other countries with legally binding provisions on placing women in top business positions.I understand Reding’s reluctance-and her frustration.I don’t like quotas either; they run counter to my belief in meritocracy,government by the capable.Bur,when one considers the obstacles to achieving the meritocratic ideal,it does look as if a fairer world must be temporarily ordered.After all,four decades of evidence has now shown that corporations in Europe as the US are evading the meritocratic hiring and promotion of women to top position —no matter how much“soft pressure”is put upon them.When women do break through to the summit of corporate power--as,for example,Sheryl Sandberg recently did at Facebook—they attract massive attention precisely because they remain the exception to the rule.If appropriate pubic policies were in place to help all women---whether CEOs or their children’s caregivers--and all families,Sandberg would be no more newsworthy than any other highly capable person living in a more just society.36.In the European corporate workplace,generally_____.[A]women take the lead[B]men have the final say[C]corporate

But Dr Uri Simonsohn speculated that an inability to consider the big 3 was leading decision-makers to be biased by the daily samples of information they were working with. 4 , he theorized that a judges 5 of appearing too soft 6 crime might be more likely to send someone to prison 7 he had already sentenced five or six other defendants only to forced community service on that day.To 8 this idea, he turned to the university-admissions process. In theory, the 9 of an applicant should not depend on the few others 10 randomly for interview during the same day, but Dr Simonsohn suspected the truth was 11 .He studied the results of 9,323 MBA interviews 12 by 31 admissions officers. The interviews had 13 applicants on a scale of one to five .This scale 14 numerous factors into consideration. The scores were 15 used in conjunction with an applicant’s score on the Graduate Management Admission Test, or GMAT, a standardized exam which is 16 out of 800 points, to make a decision on whether to accept him or herDr Simonsohn found if the score of the previous candidate in a daily series of interviewees was 0.75 points or more higher than that of the one 17 that, then the score for the next applicant would 18 by an average of 0.075 points.

Answer the questions below each text by choosing [A], [B], [C] or [D]. Mark your answers on ANSWER SHEET 1. (40 points)Text 1In the 2006 film version of The Devil Wears Prada, Miranda Priestly, played by Meryl Streep, scold her unattractive assistant for imagining that high fashion doesn’t affect her. Priestly explains how the deep blue color of the assistant’s sweater descended over the years from fashion shows to department stores and to the bargain bin in which the poor girl doubtless found her garment.This top-down conception of the fashion business couldn’t be more out of date or at odds with feverish world described in Overdressed, Elizabeth Cline’s three-year indictment of “fast fashion”. In the last decades or so, advances in technology have allowed mass-market labels such as Zara, H&M, and Uniqlo to react to trends more quickly and anticipate demand more precisely. Quckier turnrounds mean less wasted inventory, more frequent releases, and more profit. Those labels encourage style-conscious consumers tosee clothes as disposal— meant to last only a wash or two, alth ough they don’t advertise that—and to renew their wardrobe every few weeks. By offering on-trend items at dirt-cheap prices, Cline argues, these brands have hijacked fashion cycles, shaking all industry long accustomed to a seasonal pace.The victims of this revolution, of course, are not limited to designers. For H&M to offer a 5.95 knit miniskirt in all its 2300-plus stores around the world, it must rely on low-wage, overseas labor, order in volumes that strain natural resources, and use massive amount of harmful chemicals.Overdressed is the fashion world’s answer to consumer activist bestsellers like Michael Pollan’s The Omnivore’s Dilemma. Mass-produced clothing, like fast food, fills a hunger and need, yet is non-durable, and wasteful,” Cline argues, Americans, she finds, buy roughly 20 billion garments a year—about 64 items per person—and no matter how much they give away, this excess leads to waste.Towards the end of Overdressed, Cline introduced her ideal, a Brooklyn woman named SKB, who, since 2008 has make all of her own clothes—and beautifully. But as Cline is the first to note, it took Beaumont decades to perfect her craft; her example, can’t be knocked off.Though several fast-fashion companies have made efforts to curb their impact on labor and the environment—including H&M, with its green Conscious Collection Line—Cline believes lasting-change can only be effected by the customer. She exhibits the idealism common to many advocates of sustainability, be it in food or in energy. Vanity is a constant; people will only start shopping more sustainably when they can’t afford to it.21. Priestly criticizes her assistant for her ______.[A] poor bargaining skill [B] insensitivity to fashion[C] obsession with high fashion [D] lack of imagination22. According to Cline, mass-market labels urge consumers to ______.[A] combat unnecessary waste [B] shut out the feverish fashion world[C] resist the influence of advertisements [D] shop for their garments more frequently23. The word “indictment” (Line 3, Para.2) is closest in meaning to[A] accusation. [B] enthusiasm. [C] indifference. [D] tolerance.24. Which of the following can be inferred from the last paragraph?[A] V anity has more often been found in idealists.[B] The fast-fashion industry ignores sustainability.[C] People are more interested in unaffordable garments.[D] Pricing is vital to environment-friendly purchasing.25. What is the subject of the text?[A] Satire on an extravagant lifestyle[B] Challenge to a high-fashion myth[C] Criticism of the fast-fashion industry[D] Exposure of a mass-market secret.Text 2An old saying has it that half of all advertising budgets are wasted-the trouble is, no one knows which half. In the internet age, at least in theory, this fraction can be much reduced. By watching what people search for, click on and say online, companies can aim “behavioural” ads at those most likely to buy.In the past couple of weeks a quarrel has illustrated the value to advertisers of such fine-grained information: Should advertisers assume that people are happy to be tracked and sent behavioural ads? Or should they have explicit permission?In December 2010 America's Federal Trade Cornmission (FTC) proposed adding a "do not track "(DNT) option to internet browsers ,so that users could tell advertisers that they did not want to be followed .Microsoft's Internet Explorer and Apple's Safari both offer DNT; Google's Chrome is due to do so this year. In February the FTC and Digital Advertising Alliance (DAA) agreed that the industry would get cracking on responding to DNT requests.On May 31st Microsoft Set off the row: It said that Internet Explorer 10, the version due to appear windows 8, would have DNT as a default.It is not yet clear how advertisers will respond. Getting a DNT signal does not oblige anyone to stop tracking, although some companies have promised to do so. Unable to tell whether someone really objects to behavioural ads or whether they are sticking with Microsoft’s default, some may ignore a DNT signal and press on anyway.Also unclear is why Microsoft has gone it alone. After all, it has an ad business too, which it says will comply with DNT requests, though it is still working out how. If it is trying to upset Google, which relies almost wholly on default will become the norm. DNT does not seem an obviously huge selling point for windows 8-though the firm has compared some of its other products favourably with Google's on that count before.Brendon Lynch, Microsoft's chief privacy officer, blogged: “we believe consumers should have more control.” Could it really be that simple?26. It is suggested in paragraph 1 that “behavioural” ads help advertisers to ______.[A] ease competition among themselves [B] lower their operational costs[C] avoid complaints from consumers [D] provide better online services27. “The industry” (Line 6,Para.3) refers to ______.[A] online advertisers [B] e-commerce conductors[C] digital information analysis [D] internet browser developers28. Bob Liodice holds that setting DNT as a default ______.[A] many cut the number of junk ads [B] fails to affect the ad industry[C] will not benefit consumers [D] goes against human nature29. Which of the following is true according to Paragraph.6?[A] DNT may not serve its intended purpose[B] Advertisers are willing to implement DNT[C] DNT is losing its popularity among consumers[D] Advertisers are obliged to offer behavioural ads30. The author’s attitude towards what Brendon Lynch said in his blog is one of ______.[A] indulgence [B] understanding [C] appreciation [D] skepticismText 3Up until a few decades ago, our visions of the future were largely - though by no means uniformly - glowingly positive. Science and technology would cure all the ills of humanity, leading to lives of fulfillment and opportunity for all.Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change. You might even be tempted to assume that humanity has little future to look forward to.But such gloominess is misplaced. The fossil record shows that many species have endured for millions of years—so why shouldn't we? Take a broader look at our species’place in the universe, and it becomes clear that we have an excellent chance of surviving for tens, if not hundreds, of thousands of years. Look up Homo sapiens in the “Red List” of threatened species of the International Union for the Conversation of Nature (IUCN) ,and you will read: “Listed as Least Concern as the species is very widely distributed, adaptable, currently increasing, and there are no major threats resulting in an overall population decline.”So what does our deep future hold? A growing number of researchers and organizations are now thinking seriously about that question. For example, the Long Now Foundation has its flagship project a medical clock that is designed to still be marking time thousands of years hence.Perhaps willfully, it may be easier to think about such lengthy timescales than about the more immediate future. The potential evolution of today’s technology, and its social consequences, is dazzlingly complicated, and it’s perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage. That's one reason why we have launched Arc, a new publication dedicated to the near future.But take a longer view and there is a surprising amount that we can say with considerable assurance. As so often, the past holds the key to the future: we have now identified enough of the long-term patterns shaping the history of the planet, and our species, to make evidence-based forecasts about the situations in which our descendants will find themselves.31. Our vision of the future used to be inspired by ______.[A] our desire for lives of fulfillment [B] our faith in science and technology[C] our awareness of potential risks [D] our belief in equal opportunity32. The IUCN’s “Red List” suggest that human being are ______.[A] a sustained species [B] a threaten to the environment[C] the world’s dominant power [D] a misplaced race33. Which of the following is true according to Paragraph 5?[A] Arc helps limit the scope of futurological studies.[B] Technology offers solutions to social problem.[C] The interest in science fiction is on the rise.[D] Our Immediate future is hard to conceive.34. To ensure the future of mankind, it is crucial to ______.[A] explore our planet’s abundant resources[B] adopt an optimistic view of the world[C] draw on our experience from the past [D] curb our ambition to reshape history35. Which of the following would be the best title for the text?[A] Uncertainty about Our Future [B] Evolution of the Human Species[C] The Ever-bright Prospects of Mankind [D] Science, Technology and HumanityText 4On a five to three vote，the Supreme Court knocked out much of Arizona’s immigration law Monday-a modest policy victory for the Obama Administration. But on the more important matter of the Construction, the decision was an 8-0 defeat for the Administration’s effort to upset. The balance of power between the federal government and the states.In Arizona v United States ，the majority overturned three of the four contested provision of Arizena’s controversial plan plan to have states and local police enforce federal immigration law. The Construction principles that Washington alone has power to “establish a uniform Rule of Naturalization” and that federal laws precede states laws are noncontroversial. Arizona had attempted to fashion state polices that ran parallel to the existing federal ones.Justice Anthory Kennedy，joined by Chief Justice John Robrts and the Court’s liberals，ruled that the state flew too close to the federal sun. on the overturned provisions the majority held the congress had deliberately “occupied the field”and Arizona had thus intruded on the federal’s privileged powers.However，the Justices said that Arizona police would be allowed to verify the legal status of people who come in contact with law enforcement .That’s because Congress has always envisioned joint federal-state immigration enforcement and explicitly encourages state officers to share information and cooperate with federal colleagues.Two of the three objecting Justice-Samuel Alito and Clarence Thomas-agreed with this Constitutional logic but disagreed about which Arizona rules conflicted with federal statute. The only major objection came from Justice Antonin Scalia, who offered an even more robust defense of state privileges going back to the alien and Sedition Acts.The 8-0 objection to President Obama turns on what Justice Samuel Alito describes in his objection as “a shocking assertion of federal executive power”. The White House argued that Arizona’s laws conflicted with its enforcement priorities ,even if state laws complied with federal statutes to the letter .In effect, the White House claimed that it claimed that it could invalidate any otherwise legitimate state law that it disagrees with.Some powers do belong exclusively to the federal government, and control of citizenship and the borders is among them. But if Congress wanted to prevent states from using their own resources to check immigration status, it could. It never did so. The administration was in essence asserting that because it didn’t want to carry out Congress’s immigration wishes, no state should be allowed to do so either. Every Justice rightly rejected this remarkable claim.36. The provisions of Arizona’s plan were overturned because they ______.[A]deprived the federal police of Constitutional powers[B]disturbed the power balance between different states[C]overstepped the authority of federal immigration law[D]contradicted both the federal and state policies37. On which of the following did the Justices agree, according to Paragraph 4?[A]Federal officers’ duty to withhold immigrants’ information[B]States’ independence from federal immigration law[C]States’ legitimate role in immigration enforcement[D]Congress’s intervention in immigration enforcement38. It can be inferred from Paragraph 5 that the Alien and Sedition Acts ______.[A]violated the Constitution [B]undermined the states’ interests[C]supported the federal statute [D]stood in favor of the states39. The White House claims that its power of enforcement ______.[A] Outweighs that held by the states [B] Is dependent on the states’ support[C] Is established by federal statutes [D] Rarely goes against state laws40. What can be learned from the last paragraph?[A] Immigration issues are usually decided by Congress.[B] Justices intended to check the power of the Administration.[C] Justices wanted to strengthen its coordination with Congress.[D] The Administration is dominant over immigration issues.Part BDirections:In the following text, some sentences have been removed.

Mark your answers on ANSWER SHEET1.（10 points）The social sciences are flourishing. As of 2005, there were almost half a millionprofessional social scientists from all fields in the world, working both inside and outside academia. According to the World Social Science Report 2010, the number of social-science students worldwide has swollen by about 11% every year since 2000.Yet this enormous resource in not contributing enough to today’s global challenges including climate change, security, sustainable development and health. (41)__________ Humanity has the necessary agro-technological tools to eradicate hunger, from genetically engineered crops to artificial fertilizers. Here, too, the problems are social: the organization and distribution of food, wealth and prosperity.(42)__________This is a shame—the community should be grasping the opportunity to raise its influence in the real world. To paraphrase the great social scientist Joseph Schumpeter: there is no radical innovation without creative destruction.Today, the social sciences are largely focused on disciplinary problems and internal scholarly debates, rather than on topics with external impact.Analyses reveal that the number of papers including the keywords “environmental changed” or “climate change” have increased rapidly since 2004, (43)__________ When social scientists do tackle practical issues, their scope is often local: Belgium is interested mainly in the effects of poverty on Belgium for example. And whether the community’s work contributes much to an overall accumulation of knowledge is doubtful.The problem is not necessarily the amount of available funding (44)__________ this is an adequate amount so long as it is aimed in the right direction. Social scientists who complain about a lack of funding should not expect more in today’s economic climate.The trick is to direct these funds better. The European Union Framework funding programs have long had a category specifically targeted at social scientists. This year, it was proposed that system be changed: Horizon 2020, a new program to be enacted in 2014,would not have such a category ,This has resulted in protests from social scientists. But the intention is not to neglect social science; rather, the complete opposite. (45) __________That should create more collaborative endeavors and help to develop projects aimed directly at solving global problems.[A] It could be that we are evolving two communities of social scientists: one that is discipline-oriented and publishing in highly specialized journals, and one that is problem- oriented and publishing elsewhere, such as policy briefs.[B] However, the numbers are still small: in 2010, about 1,600 of the 100,000 social-sciences papers published globally included one of these keywords.[C] the idea is to force social to integrate their work with other categories, including health and demographic change food security, marine research and the bio-economy, clear, efficient energy; and inclusive, innovative and secure societies.[D] the solution is to change the mindset of the academic community, and what it considers to be its main goal. Global challenges and social innovation ought to receive much more attention from scientists, especially the young ones.[E] These issues all have root causes in human behavior. All require behavioral change and social innovations, as well as technological development. Stemming climate change, for example, is as much about changing consumption patterns and promoting tax acceptance as it is about developing clean energy.[F] Despite these factors, many social scientists seem reluctant to tackle such problems. And in Europe, some are up in arms over a proposal to drop a specific funding category for social-science research and to integrate it within cross-cutting topics of sustainable development.[G] During the late 1990s , national spending on social sciences and the humanities as a percentage of all research and development funds-including government, higher education, non-profit and corporate-varied from around 4% to 25%; in most European nations, it is about 15%.Section III TranslationDirections:Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on ANSWER SHEET 2. (10 points) It is speculated that gardens arise from a basic need in the individuals who made them: the need for creative expression. There is no doubt that gardens evidence an impossible urge to create, express, fashion, and beautify and that self-expression is a basic human urge;(46) yet when one looks at the photographs of the garden created by the homeless, it strikes one that, for all their diversity of styles, these gardens speak of various other fundamental urges, beyond that of decoration and creative expression.One of these urges had to do with creating a state of peace in the midst of turbulence, a “still point of the turning world,” to borrow a phrase from T. S. Eliot. (47)A sacred place of peace, however crude it may be, is a distinctly human need, as opposed to shelter, which isa distinctly animal need. This distinction is so much so that where the latter is lacking, as it is for these unlikely gardens, the former becomes all the more urgent. Composure is a state of mind made possible by the structuring of one’s relation to one’s environment. (48) The gardens of the homeless which are in effect homeless gardens introduce from into an urban environment where it either didn’t exist or was not discernible as such. In so doing they give composure to a segment of the inarticulate environment in which they take their stand.Another urge or need that these gardens appear to respond to, or to arise from is so intrinsic that we are barely ever conscious of its abiding claims on us. When we are deprived of green, of plants, of trees, (49)most of us give into a demoralization of spirit which we usually blame on some psychological conditions, until one day we find ourselves in garden and feel the expression vanish as if by magic. In most of the homeless gardens of New Y ork City the actual cultivation of plants is unfeasible, yet even so the compositions often seem to represent attempts to call arrangement of materials, an institution of colors, small pool of water, and a frequent presence of petals or leaves as well as of stuffed animals. On display here are various fantasy elements whose reference, at some basic level, seems to be the natural world. (50)It is this implicit or explicit reference to nature that fully justifies the use of word garden though in a “liberated”sense, to describe these synthetic constructions.Section IV WritingPart A51.
