General English Admission Test For Non-English MajorPh.D. program(Harbin Institute of Technology)Passage OneQuestions 1-7 are based on the following passage:According to a recent theory, Archean-age gold-quartz vein systems were formed over two billion years ago from magmatic fluids that originated from molten granitelike bodies deep beneath the surface of the Earth. This theory is contrary to the widely held view that the systems were deposited from metamorphic fluids, that is, from fluids that formed during the dehydration of wet sedimentary rocks. The recently developed theory has considerable practical importance. Most of the gold deposits discovered during the original gold rushes were exposed at the Earth’s surface and were found because they had shed trails of alluvial gold that were easily traced by simple prospecting methods. Although these same methods still leas to an occasional discovery, most deposits not yet discovered have gone undetected because they are buried and have no surface expression.The challenge in exploration is therefore to unravel the subsurface geology of an area and pinpoint the position of buried minerals. Methods widely used today include analysis of aerial images that yield abroad geological overview, geophysical techniques that provide data on the magnetic, electrical, and mineralogical properties of the rocks being investigated, and sensitive chemical tests that are able to detect : the subtle chemical halos that often envelop mineralization. However, none of these high-technology methods are of any value if the sites to which they are applied have never mineralized, and to maximize the chances of discovery the explorer must therefore pay particular attention to selecting the ground formations most likely to be mineralized. Such ground selection relies to varying degrees on conceptual models, which take into account theoretical studies of relevant factors.These models are constructed primarily from empirical observations of known mineral deposits and from theories of ore-forming processes. The explorer uses the models to identify those geological features that are critical to the formation of the mineralization being modeled, and then tries to select areas for exploration that exhibit as many of the critical features as possible.1. The author is primarily concerned with .A. advocating a return to an older methodology.B. explaining the importance of a recent theory.C. enumerating differences between two widely used methodsD. describing events leading to a discovery2. According to passage, the widely held view of Archean-age gold-quartz vein systems is that such systemsA were formed from metamorphic fluids.B originated in molten granitelike bodiesC were formed from alluvial depositsD generally have surface expression3. The passage implies that which of the following steps would bethe first performed by explorers who wish to maximize their chances of discovering gold?A Surveying several sites known to have been formed morethan two billion years ago.B Limiting exploration to sites known to have been formedform metamorphic fluid.C Using an appropriate conceptual model to select a site forfurther exploration.D Using geophysical methods to analyze rocks over a broadarea.4. Which of the following statements about discoveries of gold deposits is supported by information in the passage?A The number of gold discover made annually has increasedbetween the time of the original gold rushes and the presentB New discoveries of gold deposits are likely to be the resultof exploration techniques designed to locate buriedmineralizationC It is unlikely that newly discovered gold deposits will everyield as much as did those deposits discovered during theoriginal gold rushes.D Modern explorers are divided on the question of the utilityof simple prospecting methods as a source of newdiscoveries of gold deposits.5. It can be inferred from the passage that which of the following is easiest to detect?A A gold-quartz vein system originating in magma tic fluids.B A gold-quartz vein system originating in metamorphic fluids.C A gold deposit that is mixed with granite.D A gold deposit that has shed alluvial gold.6. The theory mentioned in line I relates to the conceptualmodels discussed in the passage in which of the followingways?A It may furnish a valid account of ore-forming processes,and hence, can support conceptual models that have greatpractical significance.B It suggests that certain geological formations, long believedto be mineralized, are in fact mineralized thus confirming current conceptual models.C. It suggests that there may not be enough similarity acrossArchean-age gold-quartz vein systems to warrant the formulation of conceptual models.D It corrects existing theories about the chemical halos ofgold deposits, and thus provides a basis for correcting current conceptual models.7. According to the passage methods of exploring for gold thatare widely used today are based on which of the following facts?A Most of the Earth’s remaining gold deposits are stillmolten.B Most of the Earth’s remaining gold deposits are exposedat the surface.C Most of the Earth’s remaining gold deposits are buriedand have no surface expressionD Only one type of gold deposit warrants exploration. sincethe other types of gold deposits are found in regions difficult to reachPassage TwoQuestions 8-15 are based on the following passage:In choosing a method for determining climatic conditions that existed in the past, paleoclimatologists invoke four principal criteria. First, the material—rocks, lakes, vegetation, etc.—on which the method relies must be widespread enough to provide plenty of information, since analysis of material that is rarely encountered will not permit correlation with other regions or with other periods of geological history. Second in the process of formation, the material must have received an environmental signal that reflects a change in climate and that can be deciphered by modern physical or chemical means. Third, at least some of the material must have retained the signal unaffected by subsequent changes in the environment. Fourth, it must be possible to determine the time at which the inferred climatic conditions held. This last criterion is more easily met in dating marine sediments, because dating of only a small number of layers in a marine sequence allows the age of other layers to be estimated fairly reliably by extrapolation and interpolation. By contrast, because sedimentation is much less continuous in continental regions, estimating the age of a continental bed from the known ages of beds above and below is more risky.One very old method used in the investigation of past climatic conditions involves the measurement of water levels in ancient lakes.In temperate regions, there are enough lakes for correlations between them to give us a tenable picture. In arid and semiarid regions, on the other hand, the small number of lakes and the great distances between them reduce the possibilities for correlation. Moreover, since lake levels are controlled by rates of evaporation as well as by precipitation, the interpretation of such levels is ambiguous. For instance, the fact that lake levels in the semiarid southwestern United States appear to have been higher during the last ice age than they are now was at one time attributed to increased precipitation. On the basis of snowline elevations, however, it has been concluded that the climate then was not necessarily wetter than it is now, but rather that both summers and winters were cooler, resulting in reduced evaporationAnother problematic method is to reconstruct former climates on the basis of pollen profiles. The type of vegetation in a specific region is determined by identifying and counting the various pollen grains found there. Although the relationship between vegetation and climate is not as direct as the relationship between climate and lake levels, the method often works well in the temperate zones. In arid and semiarid regions in which there is not much vegetation, however, small changes in one or a few plant types can change the picture traumatically, making accurate correlations between neighboring areas difficult to obtain.8. Which of the following statements about the difference betweenmarine and continental sedimentation is supported by information in the passage?A.Data provided by dating marine sedimentation is moreconsistent with researchers’ findings in other disciplines thanis data provided by dating continental sedimentation.B.It is easier to estimate the age of a layer in a sequence ofcontinental sedimentation than it is to estimate the age of alayer in a sequence of marine sedimentation.C.Marine sedimentation is much less widespread than continentalsedimentationD.Marine sedimentation is much more continuous than iscontinental sedimentation.9. Which of the following statements best describes the organization of the passage as a whole?A.The author describes a method for determining past climaticconditions and then offers specific examples of situations inwhich it has been used.B.The author discusses the method of dating marine andcontinental sequences and then explains how dating is moredifficult with lake levels than with pollen profiles.C.The author describes the common requirements of methodsfor determining past climatic conditions and then discusses examples of such methods.D.The author describes various ways of choosing a material fordetermining past climatic conditions and then discusses how two such methods have yielded contradictory data.10. It can be inferred from the passage that paleoclimatologistshave concluded which of the following on the basis of their study of snow-line elevations in the southwest6ern United States?A.There is usually more precipitation during an ice age because ofincreased amounts of evaporationB.There was less precipitation during the last ice age than there istoday.ke levels in the semiarid southwestern United States werelower during the last ice age than they are today.D.The high lake levels during the last ice age may have been aresult of less evapo9ration rather than more precipitation.11. Which of the following would be the most likely topic for aparagraph that logically continues the passage?A.The kinds of plants normally found in arid regions.B.The effect of variation in lake levels on pollen distribution.C.The material best suited to preserving signal of climaticchanges.D.A third method fro investigating past climatic conditions.12. the author discusses lake levels in the southwestern United States in order toA.illustrate the mechanics of the relationship between lake level,evaporation, and precipitationB.provide an example of the uncertainty involved in interpretinglake levels.C.Prove that there are not enough ancient lakes with which tomake accurate correlationsD.Explain the effects of increased rates of evaporation on levelsof precipitation.13. It can be inferred from the passage that an environmental signalfound in geological material would no be useful to paleoclimatologists if it .A.had to be interpreted by modern chemical meansB.reflected a change in climate rather than a long-term climaticconditionC.was incorporated into a material as the material was formingD.also reflected subsequent environmental changes.14. According to the passage the material used to determine pastclimatic conditions must be widespread for which of thefollowing reasons?Ⅰ.Paleoclimatologists need to make comparisons between periods of geological history.Ⅱ. Paleoclimatologists need to compare materials that have supporteda wide variety of vegetationⅢ. Paleoclimatologists need to make comparisons with data collected in other regions.A.I onlyB.ⅡonlyC.I and ⅡonlyD.I and Ⅲonly15. Which of the following can be inferred from the passage aboutthe study of past climates in arid and semiarid regions?A.It is sometimes more difficult to determine past climaticconditions in arid and semiarid regions than in temperateregionsB.Although in the past more research has been done ontemperate regions, paleoclimatologists have recently turnedtheir attention to arid and semiarid regions.C.Although more information about past climates can begathered in arid and semiarid than in temperate regions, datingthis information is more difficult.D.It is difficult to study the climatic history of arid and semiaridregions because their climates have tended to vary more thanthose of temperate regions.Passage ThreeQuestions 16-22 are based on the following passage:While there is no blueprint for transforming a largely government-controlled economy into a free one, the experience of the United Kingdom since 1979 clearly shows one approach that works: privatization, in which state-owned industries are sold to private companies. By 1979, the total borrowings and losses of state-owned industries were running at about £3 billion a year. By selling many of these industries, the government has decreased these borrowings and losses, gained over £34 billion from the sales, and now receives tax revenues from the newly privatized companies. Along with a dramatically improved overall economy, the government has been able to repay 12.5 percent of the net national debt over a two-year period.In fact privatization has not only rescued individual industries and a whole economy headed for disaster, but has also raised the level of performance in every area. At British Airways and British Gas, for example, productivity per employee has risen by 20 percent. At associated British Ports. labor d isruptions common in the 1970’s and early 1980’s have now virtually disappeared. At British Telecom,there is no longer a waiting list—as there always was before privatization—to have a telephone installed.Part of this improved productivity has come about because the employees of privatized industries were given the opportunity to buy shares in their own companies. They responded enthusiastically to the offer of shares; at British Aerospace 89 percent of the eligible work force bought shares; at Associated British Ports 90 percent; and at British Telecom 92 percent. When people have a personal stake in something, they think about it, care about it, work to make it prosper. At the National Freight Consortium, the new employee-owners grew so concerned about t heir company’s profits that during wage negotiations they actually pressed their union to lower its wage demands. Some economists have suggested that giving away free shares would provide a needed acceleration of the privatization process. Yet they miss Th omas Paine’s point that “what we obtain too cheap we esteem too lightly” In order for the far-ranging benefits of individual ownership to be achieved by owners, companies, and countries, employees and other individuals must make their own decisions to buy, and they must commit some of their own resources to the choice.16. According to the passage all of the following were benefits ofprivatizing state owned industries in the United KingdomEXCEPTA.Privatized industries paid taxes to the governmentB.The government gained revenue from selling state-ownedindustriesC.The government repaid some of its national debtD.Profits from industries that were still state-owned increased17. According to the passage, which of the following resulted inincreased productivity in companies that have been privatized?A.A large number of employees chose to purchase shares in theircompanies.B.Free shares were widely distributed to individual shareholders.C.The government ceased to regulate major industries.D.Unions conducted wage negotiations fro employees.18. It can be inferred from the passage that the author considers labor disruptions to beA.an inevitable problem in a weak national economyB.a positive sign of employee concern about a companyC.a predictor of employee reactions to a company’s offer to sellshares to themD.a deterrence to high performance levels in an industry.19. The passage supports which of the following statements aboutemployees buying shares in their won companies?A.At three different companies, approximately nine out ten of theworkers were eligible to buy shares in their companies.B.Approximately 90%of the eligible workers at three differentcompanies chose to buy shares in their companies. C.The opportunity to buy shares was discouraged by at least somelabor unions.panies that demonstrated the highest productivity were thefirst to allow their employees the opportunity to buy shares. 20. Which of the following statements is most consistent with the principle described in L25-26?A.A democratic government that decides it is inappropriate toown a particular industry has in no way abdicated its responsibilities as guardian of the public interest.B.The ideal way for a government to protect employee interests isto force companies to maintain their share of a competitive market without government subsidies.C.The failure to harness the power of self-interest is an importantreason that state-owned industries perform poorlyernments that want to implement privatization programsmust try to eliminate all resistance to the free-market system. 21. Which of the following can be inferred from the passage aboutthe privatization process in the United Kingdom?A.It depends to a potentially dangerous degree on individualownership of shares.B.It conforms in its mos t general outlines to Thomas Paine’sprescription for business ownership.C.It was originally conceived to include some giving away of freeshares.D.It is taking place more slowly than some economists suggest isnecessary.22. The quotation in L32-33 is most probably used to .A.counter a position that the author of the passage believes isincorrect.B.State a solution to a problem described in the previous sentence.C.Show how opponents of the viewpoint of the author of thepassage have supported their arguments.D.point out a paradox contained in a controversial viewpoint.Passage FourQuestions 23-30 are based on the following passage:Historians of women’s labor in the United States at first largely disregarded the story of female service workers—women earning wages in occupations such as salesclerk, domestic servant, and office secretary. These historians focused instead on factory work, primarily because it seemed so different from traditional,unpaid “women’s work ”in the home, and because the underlying economic forces of industrialism were presumed to be gender-blind and hence emancipation in effect. Unfortunately, emancipation has been less profound than expected, for not even industrial wage labor has escaped continued sex segregation in the workplace.To explain this unfinished revolution in the status of women, historians have recently begun to emphasize the way a prevailing definition of femininity often determines the kinds of work allocated to women, even when such allocation is inappropriate to new conditions. For instance, early textile-mill entrepreneurs, in justifying women’s employment in wage labor, made much of the assumption that women were by nature skillful at detailed tasks and patient in carrying out repetitive chores; the mill owners thus imported into the new industrial order hoary stereotypes associated with the homemaking activities they presumed to have been the purview of women. Because women accepted the more unattractive new industrial tasks more readily than did men, such jobs came to be regarded as female jobs. And employers, who assumed that women’s “real” aspirations were for marriage and family life, declined to pay women wages commensurate with those of men. Thus many lower-skilled, lower-paid, less secure jobs came to beperceived as “female.”More remarkable than the origin has been the persistence of such sex segregation in twentieth-century industry. Once an occupation came to be perceived as “female”, employers showed surprisingly little interest in changing that perception, even when higher profits beckoned. And despite the urgent need of the United States during the Second World War to mobilize its human resources fully, job segregation by sex characterized even he most important war industries. Moreover, once the war ended, employers quickly returned to men most of the “male” jobs that women had been permitted to master.23. According to the passage, job segregation by sex in the United States was.A.greatly diminlated by labor mobilization during the SecondWorld War.B.perpetuated by those textile-mill owners who argued in favorof women’s employment in wage laborC.one means by which women achieved greater job securityD.reluctantly challenged by employers except when theeconomic advantages were obvious24. According to the passage, historians of women’s laborfocused on factory work as a more promising area ofresearch than service-sector work because factory workA.involved the payment of higher wagesB.required skill in detailed tasksC.was assumed to be less characterized by sex segregationD.was more readily accepted by women than by men25. It can be inferred from the passage the early historians ofwomen’s labor in the United States paid little attention to women’s employment in the service sector of the economy becauseA.fewer women found employment in the service sector than infactory workB.the wages paid to workers in the service sector were muchmore short-term than in factory workC.women’s employment in the service sector tended to bemuch more short-term than in factory workD.employment in the service sector seemed to have much incommon with the unpaid work associated with homemaking 26. The passage supports which of the following statements aboutthe early mill owners mentioned in the second paragraph? A.They hoped that by creating relatively unattractive“female” jobs they would discourage women from losing interest in marriage and family life.B.They sought to increase the size of the available labor forceas a means to keep men’s wages low.C.They argued that women were inherently suited to do well inparticular kinds of factory workD.They felt guilty about disturbing the traditional division oflabor in family.27.It can be inferred from the passage that the “unfinishedrevolution” the author mentions in L11 refers to theA.entry of women into the industrial labor market.B.Development of a new definition of femininity unrelated tothe economic forces of industrialismC.Introduction of equal pay for equal work in all professionsD.Emancipation of women wage earners fromgender-determined job allocation28. The passage supports which of the following statements about hiring policies in the United States?A.After a crisis many formerly “male ”jobs are reclassified as“female” jobs.B.Industrial employers generally prefer to hire women withprevious experience as homemakersC.Post-Second World War hiring policies caused women to losemany of their wartime gains in employment opportunity.D.Even war industries during the Second World War werereluctant to hire women for factory work.29. Which of the following words best expresses the opinion ofthe author of the passage concerning the notion that womenare more skillful than men in carrying out details tasks?A.“patient” (line17)B.“repetitive” (line18)C.“hoary” (line19)D.“homemaking” (line19)30. Which of the following best describes the relationship of thefinal paragraph to the passage as a whole?A.The central idea is reinforced by the citation of evidence drawnfrom twentieth-century history.B.The central idea is restated in such a way as to form a transitionto a new topic for discussionC.The central idea is restated and juxtaposed with evidence thatmight appear to contradict it.D.A partial exception to the generalizations of the central idea isdismissed unimportant.Passage FiveQuestions 31-36 are based on the following passage:Two modes of argumentation have been used on behalf ofwomen’s emancipation in Western societies. Arguments in what could be called the “relational” feminist tradition maintain the doctrine of “equality in difference”, or equity as distinct for equality. They posit that biological distinctions between the sexes result in a necessary sexual division of labor in the family and throughout society and that women’s procreative labor is cu rrently undervalued by society, to the disadvantage of women. By contrast, the individualist feminist tradition emphasizes individual human rights and celebrates women’s quest for personal autonomy, while downplaying the importance of gender roles and minimizing discussion of childbearing and its attendant responsibilities.Before the late nineteenth century, these views coexisted within the feminist movement, often within the writings of the same individual. Between 1890and 1920, however, relational feminism, which had been the dominant strain in feminist thought, and which still predominates among European and non-western feminists, lost ground in England and the United States. Because the concept of individual rights was already well established in the Anglo-Saxon legal and political tradition, individualist feminism came to predominate in England-speaking countries. At the same time, the goals of the two approaches began to seem increasingly irreconcilable. Individualist feminists began to advocate a totally gender-blind system with equaleducational and economic opportunities outside the home should be available for all women, continued to emphasize women’s special contributions to society as homemakers and mothers; they demanded special treatment including protective legislation for women workers. State-sponsored maternity benefits, and paid compensation for housework.Relational arguments have a major pitfall: because they underline women’s physiological and psychological distinctiveness, they are often appropriated by political adversaries and used to endorse male privilege. But the individualist approach, by attacking gender roles, denying the significance of physiological difference, and condemning existing familial institutions as hopelessly patriarchal, has often simply treated as irrelevant the family roles important to many women. If the individualist framework, with its claim for women’s autonomy, could be harmonized with the family-oriented concerns of relational feminists, a more fruitful model for contemporary feminist politics could emerge.31. The author of the passage alludes to the well-established natureof the concept of individual rights in the Anglo-Saxon legal andpolitical tradition in order toA.illustrate the influence of individualist feminist thought on moregeneral intellectual trends in English history.B.Argue that feminism was already a part of the largerAnglo-Saxon intellectual tradition, even though this has often gone unnoticed by critics of women’s emancipationC.Explain the decline in individualist thinking among feminists innon-English-speaking countries.D.Help account for an increasing shift toward individualistfeminism among feminists in English-speaking countries.32. The passage suggests that the author of the passage believes which of the following?A.The predominance of individualist feminism inEnglish-speaking countries is a historical phenomenon, the causes of which have not yet been investigated.B.The individualist and relational feminist views are irreconcilable,given their theoretical differences concerning the foundations of society.C.A consensus concerning the direction of future feminist politicswill probably soon emerge, given the awareness among feminists of the need for cooperation among women.D.Political adversaries of feminism often misuse argumentspredicated on differences between the sexes to argue that the existing social system should be maintained.33. It can be inferred from the passage that the individualist。

For the rest of the decade, she apparently managed both roles withoutattracting much eroticism. But by the end of 2009, Ms. Simmons was under fire for having sat on Goldman’s compensation committee, how could she have let those enormous bonus payouts pass unremarked? By February the next year Ms. Simmons had left the board. The position was just taking up too much time, she said.Outside directors are supposed to serve as helpful, yet less biased, advisers on a firm’s board. Having made their wealth and their reputations elsewhere, they presumably have enough independence to disagree with the chiefproposals. If the sky and the share executive’sprice is falling, outside directors should be ableto give advice based on having weathered their own crises.The researchers from Ohio University useda database hat covered more than 10,000 firms and more than 64,000 different directors between 1989 and 2004. Then they simply checked which directors stayed from one proxystatement to the next. The most likely reason for departing a board was age, so the researchers concentrated on those “surprise” disappearances by directors under the age of 70.They fount that after a surprise departure, the probability that the company will subsequentlyhave to restate earnings increased by nearly 20%. The likelihood of being named in a federalclass-action lawsuit also increases, and the stockis likely to perform worse. The effect tended tobe larger for larger firms. Although a correlation between them leaving and subsequent bad performance at the firm is suggestive, it does not mean that such directorsare always jumping off a sinking ship. OftenLeaving riskier, smaller firmsthey “trade u p.” for larger and more stable firms.But the researchers believe that outside directors have an easier time of avoiding a blowto their reputations if they leave a firm beforebad news breaks, even if a review of history shows they were on the board at the time anywrongdoing occurred. Firms who want to keep their outside directors through tough times may have to create incentives. Otherwise outside directors will follow the example of Ms. Simmons, once again very popular on campus.21. According to Paragraph 1, Ms. Simmons was criticized for .A. gaining excessive profitsB. failing to fulfill her dutyC. refusing to make compromisesD. leaving the board in tough times22. We learn from Paragraph 2 that outside directors are supposed to be .A. generous investorsB. unbiased executivesC. share price forecastersD. independent advisers23. According to the researchers from Ohiosurprise University after an outside director’s departure, the firm is likely to .A. become more stableB. report increased earningsC. do less well in the stock marketD. perform worse in lawsuits24. It can be inferred from the last paragraph that outside directors .A. may stay for the attractive offers from the firmB. have often had records of wrongdoings in the firmC. are accustomed to stress-free work in the firmD. will decline incentives from the firm25. The author’s attitude toward the role of outside directors is .A. permissiveB. positiveC. scornfulD. criticalText 2 The Economist Jun 10th 2010 DBCAA Whatever happened to the death of newspaper? A year ago the end seemed near. The recession threatened to remove the advertising and readers that had not alreadyfled to the internet. Newspapers like the San Francisco Chronicle were chronicling their own doom. America’s Federal Trade commission launched a round of talks about how to save newspapers. Should they become charitable corporations? Should the state subsidize them? It will hold another meeting soon. But the discussions now seem out of date.In much of the world there is the sign of crisis. German and Brazilian papers have shrugged off the recession. Even American newspapers, which inhabit the most troubled come of the global industry, have not only survived but often returned to profit. Not the 20% profit margins that were routine a few years ago, but profit all the same.It has not been much fun. Many papers stayed afloat by pushing journalists overboard. The American Society of News Editors reckons that 13,500 newsroom jobs have gone since 2007. Readers are paying more for slimmer products. Some papers even had the nerve to refusedelivery to distant suburbs. Yet these desperate measures have proved the right ones and, sadly for many journalists, they can be pushed further.Newspapers are becoming more balanced businesses, with a healthier mix of revenues from readers and advertisers. American papers have long been highly unusual in their reliance on ads. Fully 87% of their revenues came from advertising in 2008, according to the Organization for Economic Cooperation & Development (OECD). In Japan the proportionis 35%. Not surprisingly, Japanese newspapers are much more stable.The whirlwind that swept through newsrooms harmed everybody, but much of the damage has been concentrated in areas where newspaper are least distinctive. Car and film reviewers have gone. So have science and general business reporters. Foreign bureaus have been savagely cut off. Newspapers are less complete as a result. But completeness is nolonger a virtue in the newspaper business.26. By saying “Newspapers l ike … their own doom” (Lines 3-4, Para. 1), the author indicates that newspaper .A. neglected the sign of crisis[B]failed to get state subsidies[C]were not charitable corporations[D]were in a desperate situation27. Some newspapers refused delivery to distant suburbs probably because .[A]readers threatened to pay less[B]newspapers wanted to reduce costs[C]journalists reported little about these areas[D]subscribers complained about slimmer products28.

I. Bill and lining up at the marriage bureaus.But when it came to their houses, it was a time of common sense and a belief that less could truly be more. During the Depression andthe war, Americans had learned to live with less,and that restraint, in combination with the postwar confidence in the future, made small, efficient housing positively stylish.Economic condition was only a stimulus forthe trend toward efficient living. The phrase “less is more” was actually first popularized by a German, the architect Ludwig Mies van der Rohe, who like other people associated with the Bauhaus, a school of design, emigrated to the United States before World War II and took upposts at American architecture schools. Thesedesigners came to exert enormous influence onthe course of American architecture, but none more so than Mies.Mies’s signature phrase means that less decoration, properly organized, has more impact than a lot. Elegance, he believed, did not derive from abundance. Like other modern architects, he employed metal, glass and laminated wood-materials that we take for granted today but that in the 1940s symbolizedthe future. Mies’s sophisticated presentation masked the fact that the spaces he designed were small and efficient, rather than big and often empty.The apartments in the elegant towers Miesbuilt on Chicago’s Lake Shore Drive, for example, were smaller—two-bedroom units under 1,000 square feet—than those in their older neighbors along the city’s Gold Coast. But they were popular because of their airy glass walls, the views they afforded and the elegancedetails and proportions, theof the buildings’ architectural equivalent of the abstract art so popular at the time.was not entirely The trend toward “less” foreign. In the 1930s Frank Lloyd Wright started building more modest and efficient houses-usually around 1,200 square feet-than the spreading two-story ones he had designed in the 1890s and the early 20th century.Th e “Case S tudy Houses” commissioned from talented modern architects by California Arts & Architecture magazine between 1945 and 1962 were yet another homegrown influence on the “less is more” t rend. Aesthetic effect came from the landscape, new materials and forthright detailing. In his Case Study House, Ralph Rapson may have mispredicted just how the mechanical revolution would impact everyday life — few American families acquired helicopters, though most eventually got clothes dryers — but his belief that self-sufficiency was both desirable and inevitable was widely shared.31.

Text 4 The Economist(经济学家)2010年7月10日Will the European Union make it? The question would have sounded strange not longgreatest cheer ago. Now even the project’sleaders talk of a continent facing a “Bermudaof debt, population decline and lower triangle” growth.As well as those chronic problems, the EUface an acute crisis in its economic core, the 16 countries that use the single currency. Marketshave lost faith that the euro zone’s economies, weaker or stronger, will one day converge thanks to the discipline of sharing a single currency, which denies uncompetitive membersthe quick fix of devaluation.Yet the debate about how to save Europe’s single currency from disintegration is stuck. It isstuck because the euro zone’s dominant powers, France and Germany, agree on the need for greater harmonization within the euro zone, butdisagree about what to harmonies.Germany thinks the euro must be saved bystricter rules on borrow spending and competitiveness, barked by quasi-automatic sanctions for governments that do not obey. These might include threats to freeze EU fundsfor poorer regions and EU mega-projects andeven the suspension of a country’s voting rights in EU ministerial councils. It insists that economic co-ordination should involve all 27 members of the EU club, among whom there is asmall majority for free-market liberalism and economic rigour; in the inner core alone, Germany fears, a small majority favour French interference.camp headed by FrenchA “southern” wants something different: “European economicwithin an inner core of euro-zone government” members. Translated, that means politicians intervening in monetary policy and a system of redistribution from richer to poorer members,via cheaper borrowing for governments throughcommon Eurobonds or complete fiscal transfers.Finally, figures close to the France governmenthave murmured, euro-zone members shouldagree to some fiscal and social harmonization:e.g., curbing competition in corporate-tax ratesor labour costs.It is too soon to write off the EU. It remainsthe world’s largest trading block. At its best, the European project is remarkably liberal: built around a single market of 27 rich and poor countries, its internal borders are far more opento goods, capital and labour than any comparable trading area.

Mark your answers on ANSWER SHEET 1. (10 points)Leading doctors today weigh in on the debate over the government's role in promoting public health by demanding that ministers impose "fat taxes" on unhealthy food and introduce cigarette-style warnings to childrenabout the dangers of a poor diet.The demands follow comments last week by the health secretary, Andrew Lansley, who insisted the government could not force people to make healthy choices and promised to free businesses from public health regulations.But senior medical figures want to stop fast-food outlets opening near schools, restrict advertising of products high in fat, salt or sugar, and limit sponsorship of sports events by fast-food producers such as McDonald's.They argue that government action is necessary to curb Britain's addiction to unhealthy food and help halt spiralling rates of obesity, diabetes and heart disease. Professor Terence Stephenson, president of the Royal College of Paediatrics and Child Health, said that the consumption of unhealthy food should be seen to be just as damaging as smoking or binge drinking."Thirty years ago, it would have been inconceivable to have imagined a ban onsmoking in the workplace or in pubs, and yet that is what we have now. Are we willing to be just as courageous in respect of obesity? I would suggest that we should be," said the leader of the UK's children's doctors.Lansley has alarmed health campaigners by suggesting he wants industry rather than government to take the lead. He said that manufacturers of crisps and confectionery could play a central role in the Change4Life campaign, the centrepiece of government efforts to boost healthy eating and fitness. He has also criticized the celebrity chef Jamie Oliver's high-profile attempt to improve school lunches in England as an example of how "lecturing" people was not the best way to change their behaviour.Stephenson suggested potential restrictions could include banning TV advertisements for foods high in fat, salt or sugar before the 9pm watershed and limiting them on billboards or in cinemas. "If we were really bold, we might even begin to think of high-calorie fast food in thesame way as cigarettes –by setting stringentlimits on advertising, product placement and sponsorship of sports events," he said.Such a move could affect firms such as McDonald’s, which sponsors the youth coachingscheme run by the Football Association.Fast-food chains should also stop offeringsuch as toys, cute animals and “inducements” mobile phone credit to lure young customers, Stephenson said.Professor Dinesh Bhugra, president of theRoyal College of Psychiatrists, said: “If childre are taught about the impact that food has ontheir growth, and that some things can harm, atleast information is available up front.”He also urged councils to impose“fast-food-free zones” around school andhospitals-areas within which takeaways cannotopen.A Department of Health spokesperson said:“We n eed to create a new vision for publichealth where all of society works together to gethealthy and live longer. This includes creating anew ‘responsibility deal ’ with business, built on social responsibility, not state regulation. Later this year, we will publish a white paper setting out exactly how we will achieve this.”The food industry will be alarmed that suchsenior doctors back such radical moves, especially the call to use some of the tough tactics that have been deployed against smoking over the last decade.[A] “fat taxes ” shouldbe imposed on fast-foodproducerssuch as McDonald ’s.41.AndrewLansley held that [B] the governmentshould ban fast-food outletsin theneighborhood of schools.42.Terence Stephenson agreedthat [C] “lecturing ” was an effective way to improve school lunchesin England.43.Jamie Oliver seemed tobelieve that [D]cigarette-style warnings should be introduced to childrenabout the dangers of apoor diet.44.DineshBhugra suggestedthat [E] the producers of crisps and candies could contributesignificantly to theChange4Life campaign.45.A Departmentof HealthSpokesperson propsed that [F] parents should set good examples for their children by keeping ahealthy dietat home.[G] the governmentshould strengthen thesense of responsibilityamong businesses.Section Ⅲ Translation46.

(15 points)Who would have thought that, globally, theIT industry produces about the same volume ofgreenhouse gases as the world’s airlines do ---roughly 2 percent of all CO2 emissions?Many everyday tasks take a surprising tollon the environment. A Google search can leak between 0.2 and 7.0 grams of CO2, dependingon how many attempts are needed to get theanswer. To deliver results to its users “right” quickly, then, Google has to maintain vast datacentres around the world, packed with powerful computers. While producing large quantities of CO2, these computers emit a great deal of heat, so the centres need to be well air-conditioned, which uses even more energy.However, Google and other big tech providers monitor their efficiency closely and make improvements. Monitoring is the first step on the road to reduction, but there is much moreto be done, and not just by big companies.

What’s more, the market share taken by American car brandsis on the upward trend, from 10% to nearly15%.Three reasons, in my opinion, can accountfor the changes in car market in these two years.First, the rise of Chinese cars is of little surpriseas we have seen Chinese enterprises’ commitment to developing self-owned technologies, which not only free them frompotential risks, but also bring about long-termbenefit. Second, Japanese cars, which used to behighly praised for their outstanding quality andsuperior stability, is now reeling from a crisis of confidence. Last, the improvement of Americanperformance must be attributed to thecars’ smart marketing strategy employed by American sellers. They launched a lot of marketing campaigns designed specially forChinese market, which won them applaud aswell as benefit.In order to maintain the good momentumof development, domestic cars should on onehand stick to their self-independent policy, andon the other, learn some experiences from Japanese car’s failures and Americans’ success其他客观题答案:21-25BBDAA26-30DBCBB31-35BDCDB36-40DCBAC41-45EDCFG。

China &Foreign Medical Treatment中外医疗各种原因引起的缺血、缺氧及中毒等均可造成心肌损害,肌钙蛋白I(cTnI)是心肌特异性抗原,作为心肌肌钙蛋白的亚基单位是诊断心肌损伤的特异性指标,常用于急性心肌梗死的早期诊断及预后的评估[1]。
重症监护室(ICU)入住患者具有多器官损伤,尤其是重症患者,病情复杂,病死率高,容易发生多器官衰竭。
如果重症患者合并心肌损伤,则患者病死率会大大提高。
目前有研究[2]表明,非心源性损害的重症患者,cTnI 也会有所升高,表明cTnI 不仅是判断心肌损害和预后的指标,同时也提示对危重症患者预后的评估可能具有较大的临床意义。
及时准确地对患者病情进行判断及预测严重程度,有效采取抢救干预措施,对提高患者抢救成功率及减少病死率意义重大。
该研究通过对该院2014年1月—2015年12月收治的综合ICU 126例多发伤患者血清cTnⅠ的测定,探讨其在ICU 危重症患者预后评估的临床应用价值,以期能为危重症患者的病情判断及预后预测提供参考,现报道如下。
