北京师范大学2011年博士入学英语试题与答案详解一、试题部分Part I: Listening Comprehension(略)Part II: Reading ComprehensionDirections: There are six passages in this part. Each of the passages is followed by five questions or unfinished statements. For each of them there are four choices marked A, B, C and D. choose the best one and mark your answer on the ANSWER SHEET.Passage OneIt is frequently assumed that the mechanization of work has a revolutionary effect on the lives of the people who operate the new machines and on the society into which the machines have been introduced. For example, it has been suggested that the employment of women in industry took them out of the household, their traditional sphere, and fundamentally altered their position in society. In the nineteenth century, when women began to entre factories, Jules Simon, a French politician, warned that by doing so, women would give up their femininity. Friedrich Engels, however, predicted that women would be liberated from the “social, legal, and economic subordination”of the family by technological developments that made possible the recruitment of “the whole female sex…into public industry.”Observes thus differed concerning the social desirability of mechanization’s effects, but they agreed that it would transform women’s lives.Historians, particularly those investigating the history of women, now seriously question this assumption of transforming power. They conclude that such dramatic technological innovations as the spinning jenny, the sewing machine, the typewriter, and the vacuum cleaner have not resulted in equally dramatic changes in women’s economic position or in the prevailing evaluation of women’s work. The employment of young women in textile mills during the Industrial Revolution was largely an extension of an older pattern of employment of young, single women as domestics. It was not the change in office technology, but rather the separation of secretarialwork, previously seen as an apprenticeship for beginning managers, from administrative work that in the 1880’s created a new class of “dead-end”jobs, thenceforth consider “women’s work”. The increase in the numbers of married women employed outside the home in the twentieth century had less to do with the mechanization of housework and an increase in leisure time for these women than it did with their own economic necessity and with high marriage rates that shrank the available pool of single women workers, previously, in many cases, the only women employers would hire.Women’s work has changed considerably in the past 200 years, moving from the household to the office or the factory, and later becoming mostly white-collar instead of blue-collar work. Fundamentally, however, the conditions under which women work have changed little since before the industrial revolution: the segregation of occupations by sex, lower pay for women as a group, jobs that require relatively low levels of shill and offer women little opportunity for advancement all persist, while women’s household labor remains demanding. Recent historical investigation has led to a major revision of the notion that technology is always inherently revolutionary in its effects on society. Mechanization may even have slowed any change in the traditional position of women both in the labor market and in the home.16. The main idea of the text is that mechanization_________.A. does not perform an inherently revolutionary functionB. revolutionizes the traditional values of a societyC. has caused the nature of women’s work to changeD. creates whole new classes of jobs that did not exist previously17. In relation to those historians who study the history of women, the author most probably believes that_________.A. they provide a valuable insight into the social phenomena affecting the position of womenB. their work can only be used cautiously by scholars in historical studiesC. they tend to draw less reliable conclusions than do other historiansD. their work has not had an impact on other historians’ current assumptions18. The text states that, before the twentieth century, many employers_________.A. employed women only in traditional household workB. tended to employ single rather than married womenC. resisted changing women’s roles in their social lifeD. hired only qualified women to fill the open position19. According to the author, which of the following may indicate a fundamental alteration in working women’s conditions?A. the majority of women occupy white-collar positionsB. married men are doing the same household tasks as are womenC. female workers outnumber male ones in a new class of jobsD. working women’s pay is as high as that of working men20. The function of the concluding sentence of the text is that_________.A. it sum up the general points concerning the mechanization of work in the textB. it draws a conclusion which goes beyond the evidence presented in the text as a wholeC. it restates the point concerning technology made in the sentence immediately preceding itD. it suggests a compromise between two seemingly contradictory views stated in the textPassage TwoOld people are always saying that the young are not what they were. The same comment is made from generation to generation and it is always true. It has never been truer than it is today. The young are better educated. They have a lot more money to spend and enjoy more freedom. They grow up more quickly and are not so dependent on their parents. They think more for themselves and do not blindly accept the ideals of their elders. Events which the older generation remembers vividly are nothing more than past history. This is as it should be. Every new generation is different from the one that preceded it. Today the difference is very marked indeed.The old always assume that they know best for the simple reason that they have been around a bit longer. They don’t like to feel that their values are being questioned or threatened. And this is precisely what the young are doing. They are question the assumptions of their elders and disturbing their complacency. Office hours, for instance, are nothing more than enforced slavery. Wouldn’t people work best if they were given complete freedom and responsibility? And what about clothing? Who said that all the men in the world should wear drab grey suits and convict haircuts? If we ruin our minds to more serious matters, who said that human difference can best be solved through conventional politics or by violent means? Why have the older generation so often used violence to solve their problems? Why are they so unhappy and guilt-ridden in their personal lives, so obsessed with mean ambitions and the desire to amass more and more material possessions? Can anything be right with the rat-race? Haven’t the old lost touch with all that is important in life?These are not questions the older generation can shrug off lightly. Their record over the past forty years or so hasn’t been exactly spotless. Traditionally, the young have turned to their elders for guidance. Today, the situation might be reversed. The old—if they are prepared to admit it—could learn a thing or two from their children. One of the biggest lessons they could learn is that enjoyment is not ‘sinful’. Enjoyment is a principle one could apply to all aspects of life. It is surely not wrong to enjoy your work and enjoy your leisure; to shed restricting inhibitions. It is surely not wrong to live in the present rather than in the past or future. This emphasis on the present is only to be expected because the young have grown up under the shadow of the bomb: the constant threat of complete annihilation. This is their glorious heritage. Can we be surprised that they should so often question the sanity of the generation that bequeathed it?21. Which of the following features in the young is NOT mentioned? _________.A. Better educated.B. More money and freedom.C. Independence.D. Hard work.22. What so the young reject most? _________.A. Values.B. The assumption of the elders.C. Conformity.D. Conventional ideas.23. Why do the young stress on the present? _________.A. They have grown up under the shadow of the bomb.B. They dislike the past.C. They think the present world is the best.D. They are afraid of destruction.24. What can the old learn from the young generation? _________.A. Enjoyment is not sinful.B. People should have more leisure time.C. Men might enjoy life.D. One should enjoy one’s work.Passage ThreeTwo conditions are necessary for the formation of ice: the presence of water and temperatures below freezing. Ice in the atmosphere and on the ground can assume various forms, depending on the conditions under which water is converted to its solid state. Ice that forms in the atmosphere can fall to the ground as snow, sleet, or hail. Snow is an assemblage of ice crystals in the form of flakes; sleet is a collection of frozen raindrops, which are actually ice pellets. Hail consists of rounded or jagged lumps of ice, often in layers of water. In North America, ice forms in late autumn, winter, and early spring. On very large bodies of water, it may not form until late winter because there must be several months of low temperatures to chill such large amounts of water.On puddles and small ponds, ice first freezes in a thin layer with definite crystal structure that becomes less apparent as the ice thickens. On lakes large enough to have waves, such as the Great Lakes, the first ice to form is a thin surface layer ofslush, sometimes called grease ice, which eventually grows into small floes of pancake ice. If the lake is small enough or the weather cold enough, the floes may freeze together into a fairly solid sheet of pack ice. Pack ice may cover the entire lake or be restricted to areas near the shore.Because water expands when it freezes, ice is less dense than liquid water and therefore floats rather sinks in water. As ice floats on the surface of a lake, ocean, or river, it acts as an insulator and is thus important in maintaining the balance of the ecosystem. Without the insulating effect of floating ice sheets, surface water would lose heat more rapidly, and large bodies of water such as the Arctic Ocean and Hudson Bay might freeze up completely.26. What condition is necessary for water in the atmosphere to change to its solid state? _________.A. A solid cloud cover that absorbs the sun's heat.B. A weather forecast for snow, sleet, or hailC. A position directly above a large body of waterD. A temperature below water's freezing point27. Ice that forms in the atmosphere in the form of layered lumps is known as_________.A. snowB. pack iceC. hailD. grease ice28. Why does ice form later on very large bodies of water? _________.A. Most large bodies of water are located at low elevations or low latitudes.B. It takes several months of cold temperatures to cool a large body of water.C. Large bodies of water are fed by underground springs of warmer water.D. The waves on large bodies of water prevent the water from freezing quickly.29. The word it in paragraph 3 refers to_________.A. waterB. iceC. surfaceD. river30. Which of the following is an effect of the density of ice? _________.A. Ice that forms on large lakes has a greasy consistency.B. Each ice crystal is unique, but all are six-sided structures.C. Pack ice is restricted to areas near the shore of a lake.D. Floating ice sheets prevent bodies of water from losing heat.Passage FourAlthough recent years have seen substantial reductions in noxious pollutants from individual motor vehicles, the number of such vehicles has been steadily increasing. Consequently, more than 100 cities in the United States still have levelsof carbon monoxide, particulate matter, and ozone (generated by photochemical reactions with hydrocarbons from vehicle exhaust) that exceed legally established limits. There is a growing realization that the only effective way to achieve further reductions in vehicle emissions — short of a massive shift away from the private automobile — is to replace conventional diesel fuel and gasoline withcleaner-burning fuels such as compressed natural gas, liquefied petroleum gas, ethanol, or methanol.All of these alternatives are carbon-based fuels whose molecules are smaller and simpler than those of gasoline. These molecules burn more cleanly than gasoline, in part because they have fewer, if any, carbon-carbon bonds and the hydrocarbons they do emit are less likely to generate ozone. The combustion of larger molecules, which have multiple carbon-carbon bonds involves a more complex series of reactions. These reactions increase the probability of incomplete combustion and are more likely to release uncombusted and photochemically active hydrocarbon compounds into the atmosphere. On the other hand, alternative fuels do have drawbacks. Compressed natural gas would require that vehicles have set of heavy fuel tanks — a serious liability in terms of performance and fuel efficiency — and liquefied petroleum gas faces fundamental limits on supply.Ethanol and methanol, on the other hand, have important advantages over other carbon-based alternative fuels: they have higher energy content per volume and would require minimal changes in the existing network for distributing motor fuel. Ethanol is commonly used as a gasoline supplement, but it is currently about twice as expensive as methanol, the low cost of which is one of its attractive features. Methanol’s most attractive feature, however, is that it can reduce by about 90 percent the vehicle emissions that form ozone, the most serious urban air pollutant.Like any alternative fuel, methanol has its critics. Yet much of the criticism is based on the use of “gasoline clone” vehicles that do not incorporate even the simplest design improvements that are made possible with the use of methanol. It is true, for example, that a given volume of methanol provides only about one-half of the energy that gasoline and diesel fuel do; other things being equal, the fuel tank would have to be somewhat larger and heavier. However, since methanol-fueled vehicles could be design ed to be much more efficient than “gasoline clone” vehicles fueled with methanol they would need comparatively less fuel. Vehicles incorporating only the simplest of the engine improvements that methanol makes feasible would still contribute to an immediate lessening of urban air pollution.31. The author of the text is primarily concerned with_________.A. countering a flawed argument that dismisses a possible solution to a problem.B. reconciling contradictory points of view about the nature of a problem.C. identifying the strengths of possible solutions to a problem.D. discussing a problem and arguing in favor of one solution to it.32. According to the text, incomplete combustion is more likely to occur with gasoline than with an alternative fuel because_________.A. the combustion of gasoline releases photochemically active hydrocarbons.B. the combustion of gasoline embraces an intricate set of reactions.C. gasoline molecules have a simple molecular structure.D. gasoline is composed of small molecules.33. The text suggests which of the following about air pollution? _________.A. Further attempts to reduce emissions from gasoline-fueled vehicles will not help lower urban air-pollution levels.B. Attempts to reduce the pollutants that an individual gasoline-fueled vehicle emits have been largely unsuccessful.C. Few serious attempts have been made to reduce the amount of pollutants emitted by gasoline-fueled vehicles.D. Pollutants emitted by gasoline-fueled vehicles are not the most critical source of urban air pollution.34. Which of the following most closely parallels the situation described in the first sentence of the text? _________.A. Although a town reduces its public services in order to avoid a tax increase, the town’s tax rate excee ds that of other towns in the surrounding area.B. Although a state passes strict laws to limit the type of toxic material that can be disposed of in public landfills, illegal dumping continues to increase.C. Although a town’ s citizens reduce their individual use of water, the town’s water supplies continue to dwindle because of a steady increase in the total populating of the town.D. Although a country attempts to increase the sale of domestic goods by adding a tax to the price of imported goods, the sale of imported goods within the country continues to increase.35. It can be inferred that the author of the text most likely regards the criticism of methanol as _________.A. flawed because of the assumptions on which it is based.B. inapplicable b ecause of an inconsistency in the critics’ arguments.C. misguided because of its exclusively technological focus.D. inaccurate because it ignores consumers’ concerns.Passage FiveDisease is a fluid concept influenced by societal and cultural attitudesthat change diachronically in response to new scientific and medical discoveries. Historically, doctors defined a disease according to a cluster of symptoms, and as their clinical descriptions became more sophisticated, they started to classify diseases into separate groups, so that from this medical taxonomy came new insights into disease etiology. Before the 20th century, schizophrenia and syphilitic insanity were treated as the same disease, but by early 1900 it became evident that psychoses without associated dementia represented a separate disease for which the term schizophrenia was then coined. The definition of schizophrenia continues to evolve from the psychiatric disease of the 1960s toan illness with a suspected genetic etiology, though the existence of suchan etiology remains uncertain. While an optimistic hunt is still on for thegenes involved, we must continue to define schizophrenia in terms of the presence or absence of "positive" and "negative" symptoms.Labeling someone as diseased, however, has enormous individual,social, financial, and physical implications, for irrespective of disease symptoms, the label itself may lead to significant distress. Individuals withasymptomatic conditions, including genetic variations, may be perceived by themselves or others as having a disease. It is not that labeling someone as diseased is always positive—it does have severe ramifications, affecting decisions to have children or resulting in unjust treatment by life, medical, and disability insurers--but it can be beneficial, legitimizing symptoms, clarifying issues ofpersonal responsibility, and improving accessibility to healthcare. Nevertheless, deviations from normal that are not associated with risk should not be considered synonymous with disease. Two schools—nominalist and essentialist or reductionist—have debated the clinical criteria used to label a patient as diseased. Nominalists label symptoms with a disease name, suchas schizophrenia, and do not offer an explanation of the underlying etiology,while essentialists contend that for every disease there is an underlying pathological etiology, and now argue that the essential lesion defining the disease state isa genetic abnormality.It has been suggested that diseases defined according to theessentialist tradition may be precisely wrong, whereas those defined in the nominalist traditional may be roughly accurate. But in labeling a disease state, we must consider both the phenotype (symptoms) or the genotype(genetic abnormality), for the former describes a state that places individuals at some definable risk of adverse consequences, while the latter helps suggest specific genetic or pharmacologic therapies. Thus, both clinical criteria and genetic abnormalities should be used to define a disease state, and the choice of a disease definition will vary according to what one wishes to achieve, thegenetic counseling of family members or the effective treatment of the patient.36. The author of the passage is primarily concerned with_________.A．proposing a return to a traditional taxonomical systemB．describing an way to resolve a taxonomical dilemmaC．assessing the success of a new taxonomical methodD．predicting a change in future taxonomy37. It can be inferred that the author considers the way schizophrenia has been classified by doctors after 1960 to be an example of which of the following?_________.A．A disease which resisted traditional methods of classification, but has been served well by modern methods of classificationB．A disease which has resisted modern methods of classification, and continues to require a traditional method of classificationC．A disease which satisfies modern methods of classification best, but which scientists prefer to classify through a traditional methodD．A disease which satisfies traditional methods of classification best, but which scientists prefer to classify through a modern method38. Accor ding to the passage, an adherent of the “nominalist school” would classify a rare new fever in which of the following ways? _________.A. she would wait until the disease appears in other patients, then classify it accordingly.B. she would determine whether the disease is acquired or genetic, then classify it accordingly.C. she would isolate the bacteria or virus or genetic anomaly which causes the disease, then classify it accordingly.D. she would describe the patient’s symptoms, compare them to pa tients who have had similar symptoms, then treat the pattern as a disease.39. Which of the following best describe the function of the last paragraph in relation to the passage as a whole? _________.A. it summarizes the benefits that may accrue from a perfected system of pathological taxonomy.B. it provides additional reasons why pathological taxonomy is a difficultendeavor.C. it argues for a synthesis of two methods of pathological taxonomy already inuse.D. it continues to highlight the differences between two methods of taxonomical pathological taxonomy.40. It can be inferred that which of the following situations is likely to be mostproblematic to an adherent of the “essentialist” method of pathological taxonomy?_________.A. a patient suffering from fever, in which the virus that is apparently responsiblefor the symptoms has not been isolatedB. a patient suffering from lung inflammation which, though resembling other inflammations, does not respond to any known treatmentsC. a patient suffering from a genetic anomaly whose cause may be known butwhose consequences remain unidentifiedD. a case of a patient with symptoms that may have arisen from two knowndisease of different sourcesPassage SixWe all know the situation----a good friend recommends you a restaurant and you are looking forward to a nice quiet dinner, but the meal turns out to be less peaceful than expected as you are joined, in sound, by a number of uninvited guests---- James Last, the Beatles, Mireille Mathieu, Mozart ---- depending on the landlord’s fancy. You can count yourself lucky if you happen to like what you hear coming over the loudspeakers. But what about the customers who cannot stand James Last or simply want peace and quiet? There is nothing they can do. Radio sets at home can be switched off, but not restaurant loudspeakers. Customers simply become the captive audience of sounds they do not want. Some wine bars in Austria, the home of café music, make a charge known as Schrammelmusik (music cover), which everyone has to pay. But the word is quite misleading ---- payment of the music toll gives no cover ---- quite the opposite.Music has become omnipresent. The selection in restaurants may still be a matter ofchance, though it generally reflects nothing more than the doubtful taste of piped-music suppliers. However, in other areas music has long been a means of stepping up profits. An entire branch of industry thrives on this, assembling music by the most sophisticated methods with the customer in mind ---- department store music to produce a demonstrable increase in turnover; office music to improve the working atmosphere; airport and hotel music with its soothing effect; even cowshed music with its impact on milk production.These various forms of music, however different in function, have one thing in common ---- the way in which they are produced. The ancient, venerable concepts of composition and arrangement are naturally ruled out from the start. All musical extremes are deliberately debarred. The music issuing from department store loudspeakers must have a steady volume and avoid sudden effects, notes that are too high or too low and the human voice. With one exception ---- during the Christmas rush children’s choirs may be heard encouraging sales by singing ‘Silent Night’, ‘Jingle Bells’ and so on.This music is more effective when turned low. The aim of this drizzle of canned sound is not conscious assimilation and it represents something quite new in the history of music. For thousands of years music was made to be listened to. But department store music is meant only to create a warm background. There is no contradiction in the fact that Mozart may sometimes find his way into department store music tapes, though his compositions were not meant as background jingles. But department store wallpaper music is not Mozart ---- it only appears to be. And anything unusual in classical composers, anything that lends character, is simply cut ---- development sections, accents, daring harmonies, provocative instrumentation. All we have left is a melody with no backbone which might just as well have come from a pop-song producer ---- plastic music as it were, whose components all sound exactly the same.The music is not meant to be listened to and that may explain the fact that, while we have associations and action groups against air pollution and the pollution of drinking water, so far no one has got up in arms about damage to our acoustic environment. And so our musical sensitivity will continue to be subtly and gently attacked by the piped music in department stores and offices ---- music which we hear without listening to. Its strategy takes advantage of one simple fact ---- you cannot just close your ears.41. Why does the author describe the customers as a ‘captive audience’？_________.A. They usually like the music thrown at them.B. Because they can’t escape the music.C. He wants to show how easy they are to please.D. Because they’ve paid a special charge called a ‘music toll’.42. Piped music in restaurants is different from that heard in department stores because _________.A. it’s usually very tastefulB. it’s chosen very carefully by the ownerC. it tries to create a soothing atmosphereD. it doesn’t aim to increase profits43. According to the writer, what does all piped music always avoid? _________.A. Happy songs.B. Certain instruments.C. Children’s choirs.D. Any extremes.44. From what the writer says, it’s reasonably clear that he or she ______.A. loves pop musicB. likes music in public placesC. enjoys classical musicD. is keen on Christmas carols45. The writer of the passage would probably like to ______.A. join an ‘air pollution action group’B. get rid of music just in restaurantsC. start a movement against ‘canned music’D. make people listen to the piped music in public placesPart III.

北京师范大学 2014 年 3 月考博英语真题与答案详解第一部分：试题Part I ：Reading ComprehensionDirections: There are six passages in this part. Each of the passages is followed by five questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the best one and mark your answer on the ANSER SHEET.Passage 1Taken together, income, occupation, and education are good measures of people‟s social standing. Using a layered model of stratification, most sociologists describe the class system in the United States as divided into several classes: upper, upper middle, middle, lower middle, and lower class. Each class is defined by characteristics such as income, occupational prestige, and educational attainment. The different groups are arrayed along a continuum with those with the most money, education, and prestige at the top and those with the least at the bottom.In the United States, the upper class owns the major share of corporate and personal wealth; it includes those who have held wealth for generations as well as those who have recently become rich. Only a very small proportion of people actually constitute the upper class, but they control vast amounts of wealth and power in the United States. They exercise enormous control throughout society. Most of their wealth is inherited.Despite social myths to the contrary, the best predictor of future wealth is the family into which you are born. Each year, the business magazine Forbes publishes a list of the “Forbes 400”-the four hundred wealthiest families and individuals in the country. Of all the wealth represented on the Forbes 400 list, more than half is inherited. Those on the list who could be called “self-made” were not typically of modest origins; most inherited significant assets (Forbes, 1997; Sklar and Collins, 1997). Those in the upper class with newly acquired wealth are known as the nouveau niche. Although they may have vast amounts of money, they are often not acceptedinto “old rich” circles.The upper middle class includes those with high incomes and high social prestige. They tend to be well-educated professionals or business executives. Their earnings can be quite high indeed-successful business executives can earn millions of dollars a year. It is difficult to estimate exactly how many people fall into this group because of the difficulty of drawing lines between the upper, upper middle, and middle class. Indeed, the upper middle class is often thought of as “middle class” because their lifestyle sets the standard to which many aspire, but this lifestyle is simply beyond the means of a majority of people in the United States.The middle class is hard to define; in part, being “middle class” is more than just economic position. By far the majority of Americans identity themselves as middle class even though they vary widely in lifestyle and in resources at their though they vary widely in lifestyle and in resources at their disposal. But the idea that the United States is an open-class system leads many to think that the majority have a middle-class lifestyle because, in general, people tend not to want to recognize class distinctions in the United States. Thus, the middle class becomes the ubiquitous norm even though many who call themselves middle class have a tenuous hold on this class position.In the hierarchy of social class, the lower middle class includes workers in the skilled trades and low-income bureaucratic workers, many of whom may actually define themselves as middle class. Examples are blue-collar workers (those in skilled trades who do manual labor) and many service workers, such as secretaries, hairdressers, waitresses, police, and firefighters. Medium to low income, education, and occupational prestige define the lower middle class relative to the class groups above it. The term “lower” in this class designation refers to the relative position of the group in the stratification system, but it has a pejorative sound to many people, especially to people who are members of this class.The lower class is composed primarily of the displaced and poor. People in this class have little formal education and are often unemployed or working inminimum-wage jobs. Forty percent of the poor work; 1 0 percent work year-round and full time—a proportion that has generally increased over time. Recently, the concept of the underclass has been added to the lower class. The underclass includes those who have been left behind by contemporary economic developments. Rejected from the economic system, those in the underclass may become dependent on public assistance or illegal activities.1. Why does the author mention the "Forbes 400" in paragraph 3?A. To explain the meaning of the listing that appears every yearB. To cast doubt on the claim that family income predicts individual wealthC. To give examples of successful people who have modest family connectionsD. To support the statement that most wealthy people inherit their money2. The author states that business and professional people with educational advantages are most often members of the_____.A. lower middle classB. upper middle classC. nouveau richeD. upper class3. Why do most people identify themselves as middle class in the United States?A. They have about the same lifestyle as everyone else in the countryB. They don‟t really know how to define their status because it is unclearC. They prefer not to admit that there are class distinctions in the United StatesD. They identify themselves with the majority who have normal lifestyles4. What can be inferred about poor people in the United States?A. They are not able to find entry-level jobsB. They work in jobs that require little educationC. They are service workers and manual laborersD. They do not try to find employment5. According to paragraph 7, why has the underclass emerged?A. The new term was necessary because the lower class enjoyed a higher lifestyle than it had previously.B. The increase in crime has supported a new class of people who live by engaging in illegal activities.C. Changes in the economy have caused an entire class of people to survive by welfare or crime.D. Minimum-wage jobs no longer support a class of people at a standard level in the economic system.Passage 2“The word …protection‟ is no longer taboo”. This short sentence, uttered by French President Nicolas Sarkozy late last month, may have launched a new era in economic history. Why? For decades, Western leaders have believed that lowering trade barriers and tariffs was a natural good. Doing so, they reasoned, would lead to greater economic efficiency and productivity, which in turn would improve human welfare. Championing free trade thus became a moral, not just an economic, cause.These leaders, of course, weren‟t acting out of unself ishness. They knew their economics were the most competitive, so they‟d profit most from liberalization. And developing countries feared that their economics would be swamped by superior Western productivity. Today, however, the tables have turned-though few acknowledge it. The west continues to preach free trade, but practices it less and less. Asia, meanwhile, continues to plead for special protection but practices more and more free trade.That‟s why Sarkozy‟s word were so important: he finally inj ected some honesty into the trade debate. The truth is that large parts of the West are losing faith in free trade, though few leaders admit it. Some economists are more honest. Paul Krug man is one of the few willing to losers will be in the West. Economists in the developed world used to love quoting Joseph Schumpeter, who said that “creative destruction” was an essential part of capitalist growth. But they always assumed that destruction would happen over there. When Western workers began losing jobs, suddenly their leaders began to lose faith in their principles. Things have yet to reverse completely. But there‟s clearly a negative trend in Western theory and practice.A little hypocrisy is not in itself a serious problem. The real problem is that Western governments continue to insist that they retain control of the key globaleconomic and financial institutions while drifting away from global liberalization. Look at what‟s happening at the IMF (International Monetary Fund). The Europeans have demanded that they keep the post of managing director. But all too often, Western officials put their own interests above everyone else‟s when they dominate these global institutions.The time has therefore come for the Asians-who are clearly the new winners in today‟s global economy- to provide more intellectual leadership in supporting free trade, Sadly, they have yet to do so. Unless Asians speak out, however, there‟s a real danger that Adam Smith‟s principles, which have brought so much good to the world, could gradually die. And that would leave all of us worse off, in one way or another.6. It can be inferred that “protection” (Line1, Para.1) means ______.A. improving economic efficiencyB. ending the free-trade practiceC. lowering moral standardD. raising trade tariffs7. The Western leaders preach free trade because ______.A. it is beneficial to their economicsB. it is supported by developing countriesC. it makes them keep faith in their principlesD. it is advocated by Joseph Schumpeter and Adam Smith8. By “the tables have turned” (Line 3-4, Para.2) the author implies that ______.A. the Western leaders have turned self-centeredB. the Asian leaders have become advocates of free tradeC. the developed economics have turned less competitiveD. the developing economics have become more independent9. The Western economists used to like the idea of “creative destruction” because it ______.A. set a long-term rather than short-term goalB. was an essential part of capitalist developmentC. entailed a positive rather than negative mentalityD. was meant to be the destruction of developing economics10. The author uses “IMF” as an example to illustrate the point that ______.A. European leaders are reluctant to admit they are hypocriticalB. there is an inconsistency between Western theory and practiceC. global institutions are not being led by true globalization advocatesD. European countries‟ interests are being ignored by economic leadersPassage 3Growth, reproduction, and daily metabolism all require an organism to expend energy. The expenditure of energy is essentially a process of budgeting, just as finances are budgeted. If all of one‟s money is spent on clothes, there may be none left to buy food or go to the movies. Similarly, a plant or animal cannot squander all its energy on growing a big body if none would be left over for reproduction, for this is the surest way to extinction.All organisms, therefore, allocate energy to growth, reproduction, maintenance, and storage. No choice is involved; this allocation comes as part of the genetic package from the parents. Maintenance for a given body design of an organism is relatively constant. Storage is important, but ultimately that energy will be used for maintenance, reproduction, or growth. Therefore the principal differences in energy allocation are likely to be between growth and reproduction.Almost all of an organism‟s energy can be diverted to reproduction, with very little allocated to building the body. Organ isms at this extreme are “opportunists.” At the other extreme are “competitors,” almost all of whose resources are invested in building a huge body, with a bare minimum allocated to reproduction.Dandelions are good examples of opportunists. Their seed heads raised just high enough above the ground to catch the wind, the plants are no bigger than they need be, their stems are hollow, and all the rigidity comes from their water content. Thus, a minimum investment has been made in the body that becomes a platform for seed dispersal. These very short-lived plants reproduce prolifically; that is to say they provide a constant rain of seed in the neighborhood of parent plants. A new plant will spring up wherever a seed falls on a suitable soil surface, but because they do notbuild big bodies, they cannot compete with other plants for space, water, or sunlight. These plants are termed opportunists because they rely on their seeds‟ falling into settings where competing plants have been removed by natural processes, such as along an eroding riverbank, on landslips, or where a tree falls and creates a gap in the forest canopy.Opportunists must constantly invade new areas to compensate for being displaced by more competitive species. Human landscapes of lawns, fields, or flowerbeds provide settings with bare soil and a lack of competitors that are perfect habitats for colonization by opportunists. Hence, many of the strongly opportunistic plants are the common weeds of fields and gardens.Because each individual is short-lived, the population of an opportunist species is likely to be adversely affected by drought, bad winters, or floods. If their population is tracked through time, it will be seen to be particularly unstable—soaring and plummeting in irregular cycles.The opposite of an opportunist is a competitor. These organisms tend to have big bodies, are long-lived, and spend relatively little effort each year on reproduction. An oak tree is a good example of a competitor. A massive oak claims its ground for 200 years or more, outcompeting all other would-be canopy trees by casting a dense shade and drawing up any free water in the soil. The leaves of an oak tree taste foul because they are rich in tannins, a chemical that renders them distasteful or indigestible to many organisms. The tannins are part of the defense mechanism that is essential to longevity. Although oaks produce thousands of acorns, the investment in a crop of acorns is small compared with the energy spent on building leaves, trunk, and roots. Once an oak tree becomes established, it is likely to survive minor cycles of drought and even fire. A population of oaks is likely to be relatively stable through time, and its survival is likely to depend more on its ability to withstand the pressures of competition or predation than on its ability to take advantage of chance events. It should be noted, however, that the pure opportunist or pure competitor is rare in nature, as most species fall between the extremes of a continuum, exhibiting a blendof some opportunistic and some competitive characteristics.11. The word squander in the passage is closest in meaning to____.A. extendB. transformC. activateD. waste12. According to the passage, the classification of organisms as “opportunists” o r “competitors” is determined by_____.A. how the genetic information of an organism is store and maintainedB. the way in which the organism invests its energy resourcesC. whether the climate to which the organism lives is mild or extremeD. the variety of natural resources the organism consumes in its environment13. All of the following are mentioned in paragraph 7 as contribution to the longevity of oak tree EXCEPT____.A. the capacity to create shadeB. leaves containing tanninC. the ability to withstand mild droughts and firesD. the large number of acorns the tree produces14. According to the passage, oak trees are considered competitors becauseA. they grow in areas free of opportunitiesB. they spend more energy on their leaves, trunks and roots than on their acornsC. their population tends to increase or decrease irregular cyclesD. unlike other organisms, they do not need much water or sunlight15. In paragraph 7, the author suggests that most species of organismsA. are primarily opportunistsB. are primarily competitorsC. begin as opportunists and evolved into competitorsD. have some characteristics of opportunists and some of competitorsPassage 4Many literary detectives have pored over a great puzzle concerning the writer Marcel Proust: what happened in 1909? How did Contre Saint-Beuve, an essay attacking the methods of the critic Saint Beuve, turn into the start of the novelRemembrance of Things Past? A recently published letter from Proust to the editor Vallette confirms that Fallois, the editor of the 1954 edition of Contre Saint-Beuve, made an essentially correct guess about the relationship of the essay to the novel. Fallois proposed that Proust had tried to begin a novel in 1908, abandoned it for what was to be a long demonstration of Saint-Beuve‟s blindness to the real nature of great writing, found the essay giving rise to personal memories and fictional developments, and allowed these to take over in a steadily developing novel.Draft passages in Proust‟s 1909 notebooks indicate that the transition from essay to novel began in Contre Saint-Beuve, when Proust introduced several examples to show the powerful influence that involuntary memory exerts over the creative imagination. In effect, in trying to demonstrate that the imagination is more profound and less submissive to the intellect than Saint-Beuve assumed, Proust elicited vital memories of his own and, finding subtle connections between them, began to amass the material for Remembrance. By August, Proust was writing to Vallette, informing him of his intention to develop the material as a novel. Maurice Bardeche, in Marcel Proust, romancier, has shown the importance in the drafts of Remembrance of spontaneous and apparently random associations of Proust‟s su bconscious. As incidents and reflections occurred to Proust, he continually inserted new passages altering and expanding his narrative. But he found it difficult to control the drift of his inspiration. The very richness and complexity of the meaningful relationships that kept presenting and rearranging themselves on all levels, from abstract intelligence to profound dreamy feelings, made it difficult for Proust to set them out coherently. The beginning of control came when he saw how to connect the beginning and the end of his novel.Intrigued by Proust‟s claim that he had “begun and finished” Remembrance at the same time, Henri Bonnet discovered that parts of Remembrance‟s last book were actually started in 1909. Already in that year, Proust had drafted descriptions of his novel‟s characters in their old age that would appear in the final book of Remembrance, where the permanence of art is set against the ravages of time. Theletter to Vallette, drafts of the essay and novel, and Bonnet‟s researches estab lish in broad outline the process by which Proust generated his novel out of the ruins of his essay. But those of us who hoped, with Kolb, that Kolb‟s newly published complete edition of Proust‟s correspondence for 1909 would document the process in greate r detail are disappointed. For until Proust was confident that he was at last in sight of a viable structure for Remembrance, he told few correspondents that he was producing anything more ambitious than Contre Saint-Beuve.16. The passage is primarily concerned with ______.A. the role of involuntary memory in Proust‟s writing.B. evidence concerning the genesis of Proust‟s novel Remembrance of Things Past.C. conflicting scholarly opinions about the value of studying the drafts of Remembrance of Things Past.D. Proust‟s correspondence and what it reveals about Remembrance of Things Past.17. It can be inferred from the passage that all of the following are literary detectives who havetried, by means of either scholarship or criticism, to help solve t he “great puzzle” mentioned in lines 1-2 EXCEPT ______.A. BardecheB. BonnetC. FalloisD. Vallette18. According to the passage, in drafts of Contre Saint Beuve Proust set out to show thatSaint-Beuve made which of the following mistakes as a critic?I. Saint-Beuve made no effort to study the development of a novel through its drafts and revisions.II. Saint-Beuve assigned too great a role in the creative process to a writer‟s conscious intellect.III. Saint-Beuve concentrated too much on plots and not enough on imagery and other elements ofstyle.A. II onlyB. III onlyC. I and II onlyD. I, II, and III19. Which of the following best states the author‟s attitude toward the information that scholarshave gathered about Proust‟s writi ng in 1909?A. The author is disappointed that no new documents have come to light since Fallois‟s speculations.B. The author is dissatisfied because there are too many gaps and inconsistencies in the drafts.C. The author is confident that Fallois‟s 1954 guess has been proved largely correct, but regrets that still more detailed documentation concerning Proust‟s transition from the essay to the novel has not emerged.D. The author is satisfied that Fallois‟s judgment was largely correct, but feels tha t Proust‟s early work in designing and writing the novel was probably far more deliberate than Fallois‟s description of the process would suggest.20. The author of the passage implies that which of the following would be the LEAST usefulsource of informat ion about Proust‟s transition from working on Contre Saint-Beuve to having a viable structure for Remembrance of Things Past?A. Fallois‟s comments in the 1954 edition of Contre Saint-BeuveB. Proust‟s 1909 notebooks, including the drafts of Remembrance of Things PastC. Proust‟s 1909 correspondence, excluding the letter to ValletteD. Bardeche‟s Marcel Proust, romancierPassage 5Why do some desert plants grow tall and thin like organ pipes? Why do most trees in the tropics keep their leaves year round? Why in the Arctic tundra are there no trees at all? After many years without convincing general answers, we now know much about what sets the fashion in plant design.Using terminology more characteristic of a thermal engineer than of a botanist, we can think of plants as mechanisms that must balance their heat budgets. A plant by day is staked out under the Sun with no way of sheltering itself. All day long it absorbs heat. If it did not lose as much heat as it gained, then eventually it would die: Plants get rid of their heat by warming the air around them, by evaporating water, and by radiating heat to the atmosphere and the cold, black reaches of space temperature is tolerable for the processes of life.Plants in the Arctic tundra lie close to the ground in the thin layer of still air that clings there. A foot or two above the ground are the winds of Arctic cold. Tundra plants absorb heat from the Sun and tend to warm up; they probably balance most of their heat budgets by radiating heat to space, but also by warming the still air hat is trapped among them. As long as Arctic plants are close to the ground, they can balance their heat budgets. But if they should stretch up as a tree does, they would lift their working parts, their leaves, into the streaming Arctic winds. Then it is likely that the plants could not absorb enough heat from the Sun to avoid being cooled below a critical temperature. Your heat budget does not balance if you stand tall in the Arctic.Such thinking also helps explain other characteristics of plant design. A desert plant faces the opposite problem from that of an Arctic plant the danger of overheating. It is short of water and so cannot cool itself by evaporation without dehydrating. The familiar sticklike shape of desert plants represents one of the solutions to this problem: the shape exposes the smallest possible surface to incoming solar radiation and provides the largest possible surface from which the plant can radiate heat. In tropical rain forests, by way of contrast, the scorching Sun is not a problem for plants because there is sufficient water.This working model allows us to connect the general characteristics of the forms of plants indifferent habitats with factors such as temperature, availability of water, and presence or absence of seasonal differences. Our Earth is covered with a patchwork quilt of meteorological conditions, and the patterns of this patchwork are faithfully reflected by the plants.21. The passage primarily focuses on which of the following characteristics of plants?A. Their ability to grow equally well in all environmentsB. Their effects on the Earth's atmosphereC. Their ability to store water for dry periodsD. Their ability to balance heat intake and output22. According to the passage, which of the following is most responsible for preventing trees from growing tall in the Arctic?A. The hard, frozen groundB. The small amount of available sunshineC. The cold, destructive windsD. The large amount of snow that falls each year23. The author suggests that the "sticklike shape of desert plants" lines 3-5(paragraph4)can be attributed to the______.A. inability of the plants to radiate heat to the air around themB. presence of irregular seasonal differences in the desertC. large surface area that the plants must expose to the SunD. extreme heat and aridity of the habitatPassage 6To conduct some forms of sleep research, we have to find a way to track sleepiness over the day. Some people might believe that measuring sleepiness is a fairly trivial task. Couldn‟t you, for instance, simply count the number of times a person yawns during any given hour or so?In most people‟s minds, yawning--that slow, exaggerated mouth opening with the long, deep inhalation of air, followed by a briefer exhalation--is the most obvious sign of sleepiness. It is a common behavior shared by many animals, including our pet dogs and cats but also crocodiles, snakes, birds, and even some fish. It is certainly true that sleepy people tend to yawn more than wide-awake people. It is also true that people who say they are bored by what is happening at the moment will tend to yawn more frequently. However, whether yawning is a sign that you are getting ready for sleep or that you are successfully fighting off sleep is not known. Simply stretching your body, as you might do if you have been siring in the same position for a long period of time, will often trigger a yawn.Unfortunately, yawns don‟t just indicate sleepiness. In some animals, yawning is a sign of stress. When a dog trainer sees a dog yawning in a dog obedience class, it is usually a sign that the animal is under a good deal of pressure. Perhaps the handler is pushing too hard or moving too fast for the dog to feel in control of the situation. A moment or two of play and then turning to another activity is usually enough to banish yawning for quite a while.Yawning can also be a sign of stress in humans. Once, when observing airborne troops about to take their first parachute jump, I noticed that several of the soldiers were sitting in the plane and yawning. It was l0 A.M., just after a coffee break, and I doubted that they were tired；I knew for a fact that they were far too nervous to be bored. When I asked about this, the officer in charge laughed and said it was really quite a common behavior, especially on the first jump.There is also a social aspect to yawning. Psychologists have placed actors in crowded rooms and auditoriums and had them deliberately yawn. Within moments, there is usually an increase in yawning by everyone else in the room. Similarly, people who watch films or videos of others yawning are more likely to yawn. Even just reading about yawning tends to stimulate people to yawn.The truth of the matter is that we rea lly don‟t know what purpose yawning serves. Scientists originally thought that the purpose of yawning was to increase the amount of oxygen in the blood or to release some accumulated carbon dioxide. We now know that this is not true, since increasing the concentration of carbon dioxide in the air seems not to make people more likely to yawn but to make them breathe faster to try to bring in more oxygen. On the other hand, breathing 100 percent pure oxygen does not seem to reduce the likelihood of yawning.Since yawning seems to be associated with a lot more than the need for sleep, we obviously have to find some other measure of sleepiness. Some researchers have simply tried to ask people how sleepy they feel at any time using some sort of self-rating scale. There are, however, problems with getting people to make these types of judgments. Sometimes people simply lie to the researchers when asked about how sleepy they are. This occurs because in many areas of society admitting that one is fatigued and sleepy is considered a mark of weakness or lack of ambition and drive. In other instances, people may admit they need four cups of coffee to make it through the morning, but it may never occur to them that this might be due to the fact that they are so sleepy that they need stimulation from caffeine to be able to do their required tasks. For these reasons, many researchers have developed an。

北京师范大学2012年博士入学英语试题与答案详解一、试题部分Part I: Listening Comprehension(略)Part：Reading ComprehensiveDirections: There are six passages in this part. Each of the passages is followed by five questions or unfinished statements. For each of them there are four choices marked A,B,C and D. Choose the best one and mark your answer on the ANSER SHEET.Passage OneIn 1900 the United States had only three cities with more than a million residents-New York, Chicago, and Philadelphia. By 1930,it had ten giant metropolises. The newer ones experienced remarkable growth, which reflected basic changes in the economy.Line the population of Los Angeles(114000 in 1900)rose spectacularly in the early decades of the twentieth century, increasing a dramatic 1400 percent from 1900 to 1930.A number of circumstances contributed to the meteoric rise of Los Angeles. The agricultural potential of the area was enormous if water for irrigation could be found, and the city founders had the vision and dating to obtain it by constructing a 225-mile aqueduct, completed in 1913, to tap the water of the Owens River. The city had a superb natural harbor, as well as excellent rail connections. The climate made it possible to shoot motion pictures year-round; hence Hollywood. Hollywood not only supplied jobs; it disseminated an image of the good life in Southern California on screens all across the nation. The most important single industry powering the growth of Los Angeles, however, was directly linked to the automobile. The demand for petroleum to fuel gasoline engines led to the opening of the Southern California oil fields, and made Los Angeles North America's greatest refining center.Los Angeles was a product of the auto age in another sense as well: its distinctive spatial organization depended on widespread private ownership of automobiles. Los Angeles was a decentralized metropolis, sprawling across the desert landscape over an area of 400 square miles. It was a city without a real center. The downtown businessdistrict did not grow apace with the city as a whole, and the rapid transit system designed to link the center with outlying areas withered away from disuse. Approximately 800,000 cars were registered in Los Angeles County in 1930, one per 2.7 residents. Some visitors from the east coast were dismayed at the endless urban sprawl and dismissed Los Angeles as a mere collection of suburbs in search of a city. But the freedom and mobility of a city built on wheels attracted floods of migrants to the city.21. What is the passage mainly about?( )A. The growth of cities in the United States in the early 1900'sB. The development of the Southern California oil fieldsC. Factors contributing to the growth of Los AngelesD. Industry and city planning in Los Angeles22. The author characterizes the growth of new large cities in the United States after 1900 as resulting primarily from ( )A. new economic conditionsB. images of cities shown in moviesC. new agricultural techniquesD. a large migrant population23. The word "meteoric" in line 6 is closest in meaning to ( )A. rapidB. famousC. controversialD. methodical24. According to the passage, the most important factor in the development of agriculture around Los Angeles was the ( )A. influx of "new residents to agricultural areas near the cityB. construction of an aqueductC. expansion of transportation facilitiesD. development of new connections to the city's natural harbor25. The visitors from the east coast mentioned in the passage thought that Los Angeles ( )A. was not accurately portrayed by Hollywood imagesB. lacked good suburban areas in which to liveC. had an excessively large populationD. was not really a single cityPassage TwoImagine eating everything delicious you want with none of the fat. That would be great , wouldn’t it?New “fake fat” products appeared on store shelves in the United Stat es recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, sayfood manufacturers can now eliminate fat from certain foods, Critics, however, say that the new compound can rob the body of essential vitamins and nutrients and can also cause unpleasant side effects in some people. So it is up to consumers to decide whether the new fat-free products taste good enough to keep eating.Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can’t be digested at all.Normally, special chemicals in the intestines “grab” molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatty acids.The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broken down. Manufacturers say it’s that ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular fat without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E, and K from being absorbed. It can also prevent the absorption of carotenoids, compounds that may reduce the risk of cancer, heart disease, etc.Manufacturers are adding vitamins A, D, E and K as well as carotenoids to theirproducts now. Even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming.26. We learn from the passage that olestra is a substance that ( )A. contains plenty of nutrientsB. renders foods calorie-free while retaining their vitaminsC. makes foods easily digestibleD. makes foods fat-free while keeping them delicious27. The result of the search for an easily digestible fat turned out to be ( )A. commercially uselessB. just as anticipatedC. somewhat controversialD. quite unexpected28. Olestra is different from ordinary fats in that ( )A. it passes through the intestines without being absorbedB. it facilitates the absorption of vitamins by the bodyC. it helps reduce the incidence of heart diseaseD. it prevents excessive intake of vitamins29. What is a possible effect of olestra according to some critics? ( )A. It may impair the digestive system.B. It may affect the overall fat intake.C. It may increase the risk of cancer.D. It may spoil the consumers’ appetite.30. Why are nutritionists concerned about adding vitamins to olestra? ( )A. It may lead to the over-consumption of vitamins.B. People may be induced to eat more than is necessary.C. The function of the intestines may be weakened.D. It may trigger a new wave of fake food production.Passage ThreeA “scientific” view of language was dominant among philosophers and linguistswho affected to develop a scientific analysis of human thought and behavior in the early part of this century. Under the force of this view, it was perhaps inevitable that the art of rhetoric should pass from the status of being regarded as of questionable worth (because although it might be both a source of pleasure and a means to urge people to right action, it might also be a means to distort truth and a source of misguided action) to the status of being wholly condemned. If people are regarded only as machines guided by logic, as they were by these “scientific” thinkers, rhetoric is likely to be held in low regard; for the most obvious truth about rhetoric is that it speaks to the whole person. It presents its arguments first to the person as a rational being, because persuasive discourse, if honestly conceived, always has a basis in reasoning. Logical argument is the plot, as it were, of any speech or essay that is respectfully intended to persuade people. Yet it is a characterizing feature of rhetoric that it goes beyond this and appeals to the parts of our nature that are involved in feeling, desiring, acting, and suffering. It recalls relevant instances of the emotional reactions of people to circumstances—real or fictional—that are similar to our own circumstances. Such is the purpose of both historical accounts and fables in persuasive discourse：they indicate literally or symbolically how people may react emotionally, with hope or fear, to particular circumstances. A speech attempting to persuade people can achieve little unless it takes into account the aspect of their being related to such hopes and fears.Rhetoric, then, is addressed to human beings living at particular times and in particular places. From the point of view of rhetoric, we are not merely logical thinking machines, creatures abstracted from time and space. The study of rhetoric should therefore be considered the most humanistic of the humanities, since rhetoric is not directed only to our rational selves. It takes into account what the “scientific” view leaves out. If it is a weakness to harbor feelings, then rhetoric may be thought of as dealing in weakness. But those who reject the idea of rhetoric because they believe it deals in lies and who at the same time hope to move people to action, must either be liars themselves or be very naive;pure logic has never been a motivating force unless it has been subordinated to human purposes, feelings, and desires, and thereby ceasedto be pure logic.31. According to the passage, to reject rhetoric and still hope to persuade people is( )A. an aim of most speakers and writers.B. an indication either of dishonesty or of credulity.C. a way of displaying distrus t of the audience‘s motives.D. a characteristic of most humanistic discourse.32. It can be inferred from the passage that in the late nineteenth century rhetoric was regarded as ( )A. the only necessary element of persuasive discourse.B. a dubious art in at least two ways.C. an outmoded and tedious amplification of logic.D. an open offense to the rational mind.33. The passage suggests that a speech that attempts to persuade people to act is likely to fail if it does NOT ( )A. distort the truth a little to make it more acceptable to the audience.B. appeal to the self-interest as well as the humanitarianism of the audience.C. address listeners‘ emotions as well as their intellects.D. concede the logic of other points of view.34. Which of the following persuasive devices is NOT used in the passage？( )A. A sample of an actual speech delivered by an oratorB. The contrast of different points of viewC. The repetition of key ideas and expressionsD. An analogy that seeks to explain logical argument35. Which of the following best states the author‘s main point about logical argument？( )A. It is a sterile, abstract discipline, of little use in real life.B. It is an essential element of persuasive discourse, but only one such element.C. It is an important means of persuading people to act against their desires.D. It is the lowest order of discourse because it is the least imaginative.Passage FourExtraordinary creative activity has been characterized as revolutionary, flying in the face of what is established and producing not what is acceptable but what will become accepted. According to this formulation, highly creative activity transcends the limits of an existing form and establishes a new principle of organization. However, the idea that extraordinary creativity transcends established limits is misleading when it is applied to the arts, even though it may be valid for the sciences. Differences between highly creative art and highly creative science arise in part from differences in their goals. For the sciences, a new theory is the goal and end result of the creative act. Innovative science produces new propositions in terms of which diverse phenomena can be related to one another in more coherent ways. Such phenomena as a brilliant diamond or a nesting bird are relegated to the role of data, serving as the means for formulating or testing a new theory. The goal of highly creative art is very different: the phenomenon itself becomes the direct product of the creative act. Shakespeare's Hamlet is not a tract about the behavior of indecisive princes or the uses of political power, nor is Picasso's painting Guernica primarily a propositional statement about the Spanish Civil War or the evils of fascism. What highly creative artistic activity produces is not a new generalization that transcends established limits, but rather an aesthetic particular. Aesthetic particulars produced by the highly creative artist extend or exploit, in an innovative way, the limits of an existing form, rather than transcend that form.This is not to deny that a highly creative artist sometimes establishes a new principle of organization in the history of an artistic field: the composer Monteverdi, who created music of the highest aesthetic value, comes to mind. More generally, however, whether or not a composition establishes a new principle in the history of music has little bearing on its aesthetic worth. Because they embody a new principle of organization, some musical works, such as the operas of the Florentine Camerata, are of signal historical importance, but few listeners or musicologists would include these among the great works of music. On the other hand, Mozart's The Marriage of Figaro is surely among the masterpieces of music even though its modest innovationsare confined to extending existing means. It has been said of Beethoven that he toppled the rules and freed music from the stifling confines of convention. But a close study of his compositions reveals that Beethoven overturned no fundamental rules. Rather, he was an incomparable strategist who exploited limits--the rules, forms, and conventions that he inherited from predecessors such as Haydn and Mozart, Handel and Bach--in strikingly original ways.36.The author considers a new theory that coherently relates diverse phenomena to one another to be the ( )A. basis for reaffirming a well-established scientific formulation.B. byproduct of an aesthetic experience.C. tool used by a scientist to discover a new particular.D. result of highly creative scientific activity.37.The passage supplies information for answering all of the following questions EXCEPT: ( )A. Has unusual creative activity been characterized as revolutionary?B. Did Beethoven work within a musical tradition that also included Handel and Bach?C. Is Mozart's The Marriage of Figaro an example of a creative work that transcended limits?D. Who besides Monteverdi wrote music that the author would consider to embody new principles of organization and to be of high aesthetic value?38. The author regards the idea that all highly creative artistic activity transcends limits with--- ( )A. deep skepticismB. strong indignationC. marked indifferenceD. moderate amusement39. The author implies that an innovative scientific contribution is one that ( )A. is cited with high frequency in the publications of other scientistsB. is accepted immediately by the scientific community.C. does not relegate particulars to the role of data.D. introduces a new valid generalization.40. Which of the following statements would most logically conclude the last paragraph of the passage? ( )A. Unlike Beethoven, however, even the greatest of modern composers, such as Stravinsky, did not transcend existing musical forms.B. In similar fashion, existing musical forms were even further exploited by the next generation of great European composers.C. Thus, many of the great composers displayed the same combination of talents exhibited by Monteverdi.D. By contrast, the view that creativity in the arts exploits but does not transcend limits is supported in the field of literature.Passage FiveCultural norms so completely surround people, so permeate thought and action, that we never recognize the assumptions on which their lives and their sanity rest. As one observer put it, if birds were suddenly endowed with scientific curiosity they might examine many things, but the sky itself would be overlooked as a suitable subject; if fish were to become curious about the world, it would never occur to them to begin by investigating water. For birds and fish would take the sky and sea for granted, unaware of their profound influence because they comprise the medium for every fact. Human beings, in a similarly way, occupy a symbolic universe governed by codes that are unconsciously acquired and automatically employed. So much so that they rarely notice that the ways they interpret and talk about events are distinctively different from the ways people conduct their affairs in other cultures.As long as people remain blind to the sources of their meanings, they are imprisoned within them. These cultural frames of reference are no less confining simply because they cannot be seen or touched. Whether it is an individual neurosis that keeps an individual out of contact with his neighbors, or a collective neurosis that separates neighbors of different cultures, both are forms of blindness that limit what can be experienced and what can be learned from others.It would seem that everywhere people would desire to break out of the boundaries of their own experiential worlds. Their ability to react sensitively to a wider spectrumof events and peoples requires an overcoming of such cultural parochialism. But, in fact, few attain this broader vision. Some, of course, have little opportunity for wider cultural experience, though this condition should change as the movement of people accelerates. Others do not try to widen their experience because they prefer the old and familiar, seek from their affairs only further confirmation of the correctness of their own values. Still others recoil from such experiences because they feel it dangerous to probe too deeply into the personal or cultural unconscious. Exposure may reveal how tenuous and arbitrary many cultural norms are; such exposure might force people to acquire new bases for interpreting events. And even for the many who do seek actively to enlarge the variety of human beings with whom they are capable of communicating there are still difficulties.Cultural myopia persists not merely because of inertia and habit, but chiefly because it is so difficult to overcome. One acquires a personality and a culture in childhood, long before he is capable of comprehending either of them. To survive, each person masters the perceptual orientations, cognitive biases, and communicative habits of his own culture. But once mastered, objective assessment of these same processes is awkward since the same mechanisms that are being evaluated must be used in making the evaluations.41. The examples of birds and fish are used to ( )A. show that they, too, have their respective culturesB. explain humans occupy a symbolic universe as birds and fish occupy the sky and the seaC. illustrate that human beings are unaware of the cultural codes governing themD. demonstrate the similarity between man, birds, and fish in their ways of thinking42. The term "parochialism" (Line 3, Para. 3) most possibly means ( )A. open-mindednessB. provincialismC. superiorityD. discrimination43. It can be inferred from the last two paragraphs that ( )A. everyone would like to widen their cultural scope if they canB. the obstacles to overcoming cultural parochialism lie mainly in people’s habit ofthinkingC. provided one’s brought up in a culture, he may be with bias in making cultural evaluationsD. childhood is an important stage in comprehending culture44. Which of the following statements is TRUE according to the passage? ( )A. Individual and collective neurosis might prevent communications with others.B. People in different cultures may be governed by the same cultural norms.C. People’s visions will be enlarged if only they knew that cultural differences exist.D. If cultural norms are something tangible, they won’t be so confining.45. The passage might be entitled ( )A. How to Overcome Cultural MyopiaB. Behavioral Patterns and Cultural BackgroundC. Harms of Cultural MyopiaD. Cultural Myopia-A Deep-rooted Collective NeurosisPassage SixWhen you leave a job with a traditional pension, don't assume you've lost the chance to collect it. You're entitled to whatever benefit you've earned——and you might even be entitled to take it now. “A lot of people forget they have it, or they think that by waiting until they're 65, they'll have a bigger benefit,” says Wayne Bogosian, president of the PFE Group, which provides corporate pre-retirement education.Your former employers should send you a certificate that says how much your pension is worth. If it's less than $ 5,000, or if the company offers a lump-sum payout, it will generally close your account and cash you out. It may not seem like much, but $5,000 invested over 20 years at eight percent interest is $23,000. If your pension is worth more than $ 5,000, or your company doesn't offer the lump-sum option, find out how much money you're eligible for at the plan's normal retirement age, the earlier age at which you can collect the pension, the more severe penalty for collecting it early. You'll probably still come out ahead by taking the money now and investing it.What if you left a job years ago, and you're realizing you may have unwittingly left behind a pension? Get help from the Pension Benefit Guaranty Corporation. It has an online search tool that has helped locate $47 million in lost benefits for more than 12,000 workers.If you have a traditional pension, retiring early costs more than you might expect. Most people assume you take a proportional cut for leaving before your plan's normal retirement age. For example, you might think that if you need to accrue 30 years of service and you leave three years early, you'd get a pension 90 percent of the full amount. But that's not how it works. Instead, you take an actuarial reduction, determined by the employer but often around five percent a year, for each year you leave early. So retiring three years early could leave you with only 85 percent of the total amount.When you retire early with a defined-contribution plan, the problem is you start spending investments on which you could be earning interest. If you retire when you're 55, for example, and start using the traditional pension then, by age 65 you'll have only about half of what you would have had if you'd kept working until 65.46. When one leaves a job with a traditional pension, ( )A. he tends to forget that he has the pensionB. he has no right to ask for the pensionC. he'll have a bigger benefit than if he waits until the age of 65D. he has a specified worth of pension47. If one leaves early before his plan's normal retirement age, ( )A. he'll take 90 percent of the total amount of his pensionB. he'll have half of his pension paymentsC. he'll have his pension payment reduced by 5% a yearD. he'll have only 85 percent of his full pension48. If one retires early with a defined-contribution plan, he is expected to ( )A. earn less interest.B. be better off than with a traditional pension.C. start investment immediately.D. get less Social Security benefits.49. Which of the following can be used as the subtitle for the last three paragraphs?( )A. Your Payout Is Not Guaranteed.B. The Retirement Dilemma.C. Leave Early, Lose Big.D. Take the Pension with You.50. Which of the following is NOT true? ( )A. If one leaves 3 years early on a 30-year-service basis, he won't get a pension worth 27/30ths.B. It pays to get an early retirement if one understands how retirement pension plan works.C. The Pension Benefit Guaranty Corporation helps the retiree to recover last benefits.D. If one keeps his expenses within his retirement framework, he won't be severely affected.Part III. Translation and WritingPart A TranslationTranslate the following into Chinese:Blacks have traditionally been poorly educated -- look at the crisis in urban public schools -- and deprived of the sorts of opportunities that create the vision necessary for technological ambition. Black folkways in America, those unspoken, largely unconscious patterns of thought and belief about what is possible that guide aspiration and behavior, thus do not encompass physics and calculus. Becoming an engineer -- unlike becoming a doctor or a lawyer or an insurance salesman -- has not been seen as a way up in the segregated black community. These folkways developed in response to very real historical conditions, to the limited and at best ambivalent interactions between blacks and technology in this country. Folkways, the "consciousness of the race," change at a slower pace than societal conditions do -- and so a working strategy can turn into a crippling blindness and self-limitation.Translate the following into English:“失落之城”马丘比丘坐落在秘鲁热带山地森林，直到1911 年才被美国探险家海勒姆-宾厄姆发现。

vision. Playing “action” video games improves a visual ability __51__ tasks like reading and driving at night, a new study says. The ability, called contrast sensitivity function, allows people to discern even subtle changes __52__ gray against a uniformly colored backdrop. It’s also one of the first visual aptitudes to fade with age. __53__ a regular regimen of action video game training can provide long-lasting visual power, according to work led by Daphne Bavelier of the University of Rochester. Previous research shows that gaming improves other visual skills, such as the ability to track several objects at the same time and __54__ attention to a series of fast-moving events. Bavelier said, “A lot of different aspects of the visual system are being enhanced, __55__.” The new work suggests that playing video games could someday become part of vision-correction treatments, which currently rely mainly on surgery or corrective lenses. “__56__ you’ve had eye surgery or get corrective lenses, exposing yourself to these games should help the optical system to recover faster and better, you need to retrain the brain to make use of the better, crisper information that’s coming in __57__ your improved eyesight,” Bavelier said. Expert action gamers in the study played first-person shooters Unreal Tournament 2004 and Call of Duty 2. A group of experienced nonaction gamers played The Sims 2, a “life simulation” video game. The players of nonaction video games didn’t see the same vision __58__, the study says. Bavelier and others are now trying to figure out exactly why action games __59__ seem to sharpen visual skill. It may be that locating enemies and aiming accurately is a strenuous, strength-building workout for the eyes, she said.

Most crime goes unrepor ted so it is hard to pick out trends from the data, and even reliable sets of statistics can be difficult to compare. But here is one thing we do know: those with a biological predisposition to violent behavior who are brought up in abusive homes are very likely to become lifelong criminals.Antisocial and criminal behavior tends to run in families, but no one was sure whether this was due mostly to social-environmental factors or biological ones. It turns out both are important, but the effect is most dramatic when they act together. This has been illustrated in several studies over the past six years which found that male victims of child abuse are several times as likely to become criminals and abusers themselves if they were born with a less-active version of a gene for the enzyme monoamine oxidase A (MAO-A), which breaks down neurotransmitters crucial to the regulation of aggression. Researchers recently made another key observation: kids with this “double whammy” of predisposition and an unfortunate upb ringing are likely to show signs of what’s to come at a very early age. The risk factors for long-term criminality –attention deficit hyperactivity disorder, low IQ, language difficulties –can be spotted in kindergarten. So given what we now know, should n’t we be doing everything to protect the children most at risk? No one is suggesting testing all boys to see which variant of the MAO-A gene they have, but what the science is telling us is that we should redouble efforts to tackle abusive upbringings, and even simple neglect. This will help any child, but especially those whose biology makes them vulnerable. Thankfully there is already considerable enthusiasm in both the US and the UK for converting the latest in behavioral science into parenting and social skills: both governments have schemes in place to improve parenting in families where children are at risk of receiving poor care. Some people are uncomfortable with the idea of early intervention because it implies our behavior becomes “set” as we grow up, compromising the idea of free will. That view is understandable, but it would be negligent to ignore what the studies are telling us. Indeed, the cost to society of failing to intervene －in terms of criminal damage, dealing with offenders and helping victims of crime －is bound to be greater than the cost of improving parenting. The value to the children is immeasurable. （分数：5.00）(1).Researchers have come to a consensus: to explain violent behavior ________. （分数：1.00）A.in terms of physical environmentB.form a biological perspective √C.based on the empirical dataD.in a statistical way解析：(2).When we say that antisocial and criminal behavior tends to run in families, as indicated by the recent findings, we can probably mean that ___________. （分数：1.00）A.a particular gene is passed on in familiesB.child abuse will lead to domestic violenceC.the male victims of child abuse will pass on the tendency √D.the violent predisposition is exclusively born of child abuse解析：(3).The recent observation implicated that to check the development of antisocial and criminal behavior ___________. （分数：1.00）A.boys are to be screened for the biological predispositionB.high-risk kids should be brought up in kindergartenC.it is important to spot the genes for the risk factorsD.active measures ought to be taken at an early age √解析：(4).To defend the argument against the unfavorable idea, the author makes it a point to consider ___________. （分数：1.00）A.the immeasurable value of the genetic research on behaviorB.the consequences of compromising democracyC.the huge cost of improving parenting skillsD.the greater cost of failing to intervene √解析：(5).Which of the following can be the best title for the passage? （分数：1.00）A.Parenting Strategies for KidsB.The Making of a Criminal √C.Parental EducationD.Abusive Parenting解析：Passage two After 25 years battling the mother of all viruses, have we finally got the measure of HIV? Three developments featured in this issue collectively give grounds for optimism that would have been scarcely believable a year ago in the wake of another failed vaccine and continuing problems supplying drugs to all who need them. Perhaps the most compelling hope lies in the apparent “cure” of a man wit h HIV who had also developed leukemia. Doctors treated his leukemia with a bone marrow transplant that also vanquished the virus. Now US Company Sangamo Biosciences is hoping to emulate the effect patients being cured with a single shot of gene therapy, instead of taking antiretroviral drugs for life. Antiretroviral therapy (ART) is itself another reason for optimism. Researchers at the World Health Organization have calculated that HIV could be effectively eradicated in Africa and other hard-hit places using existing drugs. The trick is to test everyone often, and give those who test positive ART as soon as possible. Because the drugs rapidly reduce circulating levels of the virus to almost zero, it would stop people passing it on through sex. By blocking the cycle of infection in this way, the virus could be virtually eradicated by 2050. Bankrolling such a long-term program would cost serious money – initially around $3.5 billion a year in South Africa alone, ring to $85 billion in total. Huge as it sounds, however, it is peanuts compared with the estimated $1.9 trillion cost of the Iraq war, or the $700 billion spent in one go propping up the US banking sector. It also look small beer compared with the costs of carrying on as usual, which the WHO says can only lead to spiraling cases and costs. The final bit of good news is that the cost of ART could keep on falling. Last Friday, GlaxoSmithKline chairman Andrew Witty said that his company would offer all its medicines to the poorest countries for at least 25 per cent less than the typical price in rich countries. GSK has already been doing this for ART, but the hope is that the company may now offer it cheaper still and that other firms will follow their lead. No one doubt the devastation caused by AIDS. In 2007, 2 million people died and 2.7 million more contracted the virus. Those dismal numbers are not going to turn around soon –and they won’t turn around at all without huge effort and investment. But at least there is renewed belief that, given the time and money, we can finally start riddling the world of this most fearsome of viruses. （分数：5.00）(1).Which is the following can be most probably perceived beyond the first paragraph? （分数：1.00）A.The end of the world.B.A candle of hope. √C.A Nobel prize.D.A Quick Fix.解析：(2).According to the passage, the apparent “cure” of the HIV patient who had also developed leukemia would ___________. （分数：1.00）A.make a promising transition from antiretroviral medication to gene therapy √B.facilitate the development of effective vaccines for the infectionpel people to draw an analogy between AIDS and leukemiaD.would change the way we look at those with AIDS解析：(3).As another bit of good news, ___________. （分数：1.00）A.HIV will be virtually wiped out first in AfricaB.the cycle of HIV infection can be broken with ART √C.the circulating levels of HIV have been limited to almost zeroD.the existing HIV drugs will be enhanced to be more effective in 25 years解析：(4).The last reason for optimism is that ___________. （分数：1.00）ernments will invest more in improving ARTB.the cost of antiretroviral therapy is on the decline √C.everybody can afford antiretroviral therapy in the worldD.the financial support of ART is coming to be no problem解析：(5).The whole passage carries a tone of ___________. （分数：1.00）A.idealismB.activismC.criticismD.optimism √解析：Passage Three Archaeology can tell us plenty about how humans looked and the way they lived tens of thousands of years ago. But what about the deeper questions? Could early humans speak, were they capable of self-conscious reflection, did they believe in anything? Such questions might seem to be beyond the scope of science. Not so. Answering them is the focus of a burgeoning field that brings together archaeology and neuroscience. It aims to chart the development of human cognitive powers. This is not easy to do. A skull gives no indication of whether its owner was capable of speech, for example. The task then is to find proxies (替代物) for key traits and behaviors that have stayed intact over millennia. Perhaps the most intriguing aspect of this endeavor is teasing out the role of culture as a force in the evolution of our mental skills. For decades, development of the brain has been seen as exclusively biological. But increasingly, that is being challenged. Take what the Cambridge archaeologist Colin Renfrew calls “the sapient (智人的) paradox (矛盾)”. Evidence suggests that the human genome, and hence the brain, has changed little in the past 60,000 years. Yet it wasn’t until about 10,000 years ago that profound changes took place in human behavior: people settled in villages and built shrines. Renfrew’s paradox is why, if the hardware was in place, did it take so long for humans to start changing the world? His answer is that the software – the culture – took a long time to develop. In particular, the intervening time saw humans vest (赋予) meaning in objects and symbols. Those meanings were developed by social interaction over successive generations, passed on through teaching, and stored in the neuronal connections of children. Culture also changes biology by modifying natural selection, sometimes in surprising ways. How is it, for example, that a human gene for making essential vitamin C became blocked by junk DNA? One answer is that our ancestors started eating fruit, so the pressure to make vitamin C “relaxed” and the gene became unnecessary. By this reasoning, early humans then became addicted to fruit, and any gene that helped them to find it was selected for. Evidence suggests that the brain is so plastic that, like genes, it can be changed by relaxing selection pressure. Our understanding of human cognitive development is still fragmented and confused, however. We have lots of proposed causes and effects, and hypotheses to explain them. Yet the potential pay-off makes answers worth searching for. If we know where the human mind came from and what changed it, perhaps we can gauge where it is going. Finding those answers will take all the ingenuity the modern human mind can muster. （分数：5.00）(1).The questions presented in the first paragraph ___________. （分数：1.00）A.seem to have no answers whateverB.are intended to dig for ancient human minds √C.are not scientific enough to be answered hereD.are raised to explore the evolution of human appearance解析：(2).The scientists find the proxy to be ___________. （分数：1.00）A.the role of culture √B.the passage of timeC.the structure of a skullD.the biological makeup of the brain解析：(3).According to Renfrew’s paradox, the transition from 60,000 to 10,000 years ago suggests that ___________. （分数：1.00）A.human civilization came too lateB.the hardware retained biologically staticC.it took so long for the software to evolve √D.there existed an interaction between gene and environment解析：(4).From the example illustrating the relation between culture and biology, we might conclude that ___________. （分数：1.00）A.the mental development has not been exclusively biologicalB.the brain and culture have not developed at the same paceC.the theory of natural selection applies to human evolution √D.vitamin C contributes to the development of the brain解析：(5).Speaking of the human mind, the author would say that ___________. （分数：1.00）A.its cognitive development is extremely slowB.to know its past is to understand its future √C.its biological evolution is hard to predictD.as the brain develops, so as the mind解析：Passage Four Despite the numerous warnings about extreme weather, rising sea levels and mass extinctions, one message seems to have got lost in the debate about the impact of climate change.A warmer world won’t just be inconvenient. Huge swathes (片) of it, including most of Europe, the US and Australia as well as all of Africa and China will actually be uninhabitable--- too hot, dry or stormy to sustain a human population. This is no mirage. It could materialize if the world warms by an average of just 4°C, which some models predict could happen as soon as 2050. This is the world our children and grandchildren are going to have to live in. So what are we going to do about it? One option is to start planning to move the at-risk human population to parts of the world where it will still be cool and wet. It might seem like a drastic move, but this thought experiment is not about scaremongering (危言耸听). Every scenario is extrapolated from predictions of the latest climate models, and some say that 4°C may actually turn out to be a conservative estimate. Clearly this glacier-free, desertified world---with its human population packed into high-rise cities closer to the poles---would be a last resort. Aside from anything else, it is far from being the most practical option: any attempt at mass migration is likely to fuel wars, political power struggles and infighting. So what are the alternatives? The most obvious answer is to radically reduce carbon dioxide levels now, by fast-tracking green technologies and urgently implementing energy-efficient measures. But the changes aren’t coming nearly quickly enough and global emissions are still rising. As a result, many scientists are now turning to “Earth’s plan B”. PlanB involves making sure we have large scale geoengineeringtechnolo gies ready and waiting to either suck CO2 out of the atmosphere or deflect the sun’s heat. Most climate scientists were once firmly against fiddling with the Earth’s thermostat, fearing that it may make a bad situation even worse, or provide politicians with an excuse to sit on their hands and do nothing. Now they reluctantly acknowledge the sad truth that we haven’t managed to reorder the world fast enough to reduce CO2 emissions and that perhaps, given enough funding research and political muscle, we can indeed design, test and regulate geoengineering projects in time to avert the more horrifying consequences of climate change. Whatever we do, now is the time to act. The alternative is to plan for a hothouse world that none of us would recognize as home.（分数：5.00）(1).To begin with, the author is trying to remind us of ____________. （分数：1.00）A.the likelihood of climate change making life inconvenient √B.the warning against worsening climate changeC.the inevitable consequence of global warmingD.the misconception of a warmer world解析：(2).As the thought experiment shows, those at risk from global warming will ____________. （分数：1.00）A.live with the temperature raised by an average of 4°CB.have nowhere to go but live in the desertC.become victims as soon as 2050D.move closer to the poles √解析：(3).It is clear from the passage that a practical approach to global warming is _________. （分数：1.00）A.to reduce massively CO2 emissions √B.to take protective measures by 2025C.to prepare a blueprint for mass migrationsD.to launch habitual constructions closer to the poles解析：(4).Earth’s plan B is ambitious enough ___________. （分数：1.00）A.to stop climate scientists making a bad situation even worseB.to remove the sources of CO2 emissions altogetherC.to regulate geoengineering projects for efficiencyD.to manage the Earth’s thermostat√解析：(5).Which of the following statements are the supporters of “Earth’s plan B” for? （分数：1.00）A.It’s Time to Go GreenB.Energy-efficient measures must be taken √C.Mass migration to the poles is inevitableD.For the Planet’s Geoengineer or Catatrophe解析：Passage Five Brittany Donovan was born 13 years ago in Pennsylvania. Her biological father was sperm donor G738. Unbeknownst to Brittany’s m other, G738 carried a genetic defect known as fragile X-a mutation that all female children born from his sperm will inherit, and which causes mental impairment, behavioral problems and atypical social development. Last week, Brittany was given the green l ight to sue the sperm bank, Idant Laboratories of New York, under the state’s product liability laws. These laws were designed to allow consumers to seek compensation from companies whose products are defective and cause harm. Nobody expected them to be applied to donor sperm.Thousands of people in the US have purchased sperm from sperm banks on the promise that the donor’s history has been carefully scrutinized and his sample rigorously tested, only for some of them to discover that they have been sold a batch of bad seed. Some parents learn about genetic anomalies after their disabled child is born and they press the sperm bank for more information. Others realize it when they contact biological half-siblings who have the same disorder. So will Donovan vs Idant laboratories open the floodgates? It seems unlikely. New York’s product liability laws are highly unusual in that they consider donor sperm to be a product just like any other. Most other US states grant special status to blood products and body parts, including sperm. In these states, donor sperm is not considered a “product” in the usual sense, despite the fact that it is tested, processed, packaged, catalogued, marketed and sold. Similarly, European Union product liability law could not be used in this way. Even if this lawsuit is an isolated case, it still raises some difficult questions. First, to what lengths should sperm banks go to ensure they are supplying defect-free sperm? As we learn more and more about human genetics, there is growing list of tests that could be performed. Nobody would deny that donor sperm carrying the fragile X mutation should be screened out--- and there is a test that can do so ---but what about more subtle defects, such as language impairment or susceptibility to earl y Alzheimer’s? Donovan vs Idant Laboratories also serves as a reminder of the nature of the trade in human gametes. Sperm bank catalogues can give the impression that babies are as guaranteed as dishwashers. The Donovans are entitled to their day in court, but in allowing the product liability laws to be used in this way, the legal system is not doing much to dispel that notion. （分数：5.00）(1).Donovan sued Idant Laboratories for ______________. （分数：1.00）A.a cheat in boasting its biological productsB.donor sperm as a productC.problematic donor sperm √D.a breach of confidentiality解析：(2).It can be inferred from the passage that thousands of people in the US purchase sperm_____________. （分数：1.00）A.without knowing its potential dangers √B.regardless of repeated warningsC.for the reason of quality supplyD.for their desperate needs解析：(3).The question from the case is whether ___________. （分数：1.00）A.people are entitled to donor spermB.donated sperm should be just a product √C.Donovan is allowed to sue the sperm bankD.Donovan’s health problems have been clinically certified解析：(4).It seems that sperm banks are in no position to _______________. （分数：1.00）A.treat donor sperm as a productB.screen out the fragile X mutationC.manage their business as others do in NYD.guarantee sperm absolutely free of any defect √解析：(5).The statement Sperm bank catalogues can give the impression that babies are as guaranteed as dishwashers implies that _____________. （分数：1.00）A.Donovan will surely win the case in courtB.any product could have a defect in one way or another。

Now millions of people are saving on their heating bills with the EP Portable Heater. With over one million satisfied customers around the world, the new EP heats better and faster, saves more on heating bills, and runs almost silent.The EP has no exposed heating parts that can cause a fire. The outside of EP only gets warm to the touch so that it will not burn children or pets.The EP will not reduce oxygen in the room. With other heaters, you ’ ll notice thatyou get sleepy when the heat comes on because they are burning up oxygen.The advanced EP also heats the room evenly, wall to wall and floor to ceiling. It comfortably covers an area up to 350 square feet. Other heaters heat rooms unevenly with most of the heat concentrated to the center of the room. And they only heat an area a few feet around the heater. With the EP, the temperature will not vary in any part of the room.The EP comes with a 3-year warranty( 保修 ) and a 60-day. No questions asked. Satisfaction guarantee. If you are not totally satisfied, return it to our expertise and your money will be given back to you.Now, we have a special offer for 10 days, during which you can enjoy a half price discount and a free delivery. if you order that, we reserve the right to either accept or reject order requests at the discounted price.56.What is mainly discussed in paragraph 2?A. the heat of the EPB. the safety of the EPC. the appearance of the EPD. the material of the EP57.From the passage, we can learn that the EP _________.A. doesn ’ t burn up oxygenB. runs without any noiseC. makes people get sleepyD. is unsuitable for children and pets58.The underlined word“ evenly” in paragraph 4 probably .meansA. continuouslyB. separatelyC. quicklyD. equally59.The main purpose of the passage is to_______.A. persuade people to buy the productB. advise people to save on heating billsC. report the new development of portable heatersD. compare the difference of different heart brandsBTaIL SpinTwo dolphins race around in a big pool in the OceanPark. The smaller dolphin Grace, shown off a few of hertricks, turning around and waving hello to the crowd. Themost amazing thing about her, however, is that sheswimming at all. She doesn t have a’tail.Grace lost her tail as a baby when she got caught up in a fish trap.When the dolphin arrived at the Ocean Park in December 2005, she was fighting for her life.“ Is she going to make it?” Her trainer, Abbey Stone, feared the worst. Gracemakedid it --- but hertail didn’ t. She ended up losing her flukes and the lower part of her peduncle.Over the past six years, she has learned to swim without her tail. Dolphins swim by movingtheir flukes and peduncle up and down. Grace taught herself to move another way---like a fish!She pushed herself forward through the water by moving her peduncles from side to side.The movement put harmful pressure on Grace’ s backbone. So a company offered to create a man-made tail for her. The tail had to be strong enough to stay on Grace as she swam but softenough that it wouldn’ t hurt her.The first time Grace wore the artificial tail. She soon shook it off and let it sink in the bottomof the pool. Now, she is still learning to use the tail. Some days she wears it for an hour at a time,others not at all.“ Thenecessarytaili for’t her to feel comfortable,” says Stone,“ but it helps tokeep that range of motion( 动作 ) and build muscles( 肌肉 ).”Now, the dolphin is about to get an even happier ending. This month, Grace will star inDolphin Tale, a film that focus on her rescue and recovery. Her progress has inspired more thanjust a new movie. Many people travel from near and far to meet her. Seeing Grace swim with herman-made tail gives people so much courage.60. When Grace first arrived at the Ocean Park, her trainer worried about her.A. physical buildB. potential abilityC. chance of survivalD. adaptation to the surroundings.61. A man-made tail is created for Grace to _________.A. let her recover fasterB. make her comfortableC. adjust her way of swimmingD. help her perform better tricks62. The story of Grace inspires people to_______.A. stick to their dreamsB. treat animals friendlyC. treasure what they haveD. face difficulties bravelyCDoes Fame Drive You Crazy?Although being famous might sound like a dream come true, today’ s star, feeling like zooanimals, face pressures that few of us can imagine. They are at the center of much of the world’ s attention. Paparazzi ( 狗仔队 ) camp outside their homes, cameras ready. Tabloids (小报) publishthrilling stories about their personal lives. Just imagine not being able to do anything withoutbeing photographed or interrupted for a signature.According to psychologist Christina Villareal, celebrities—famous people —worryconstantly about their public appearance. Eventually, they start to lose track of who they really are,seeing themselves the way their fans imagine them, not as the people they were before everyoneknew their names.“ Over time,” Villareal says,“ they feel separated and alone.”The phenomenon of tracking celebrities has been around for ages. In the 4th century B.C.,painters followed Alexander the Great into battle, hoping to picture his victories for his admirers.When Charles Dickens visited America in the 19th century, his sold-out readings attractedthousands of fans, leading him to complain ( 诉苦 ) about his lack of privacy. Tabloids of the 1920sand 1930s ran articles about film-stars in much the same way that modern tabloids and websites do.Being a public figure today, however, is a lot more difficult than it used to be. Superstars cannotmove about without worrying about photographers with modern cameras. When they say somethingsilly or do something ridiculous, there is always the Internet to spread the news inminutes and keep their“ story” alive forever.If fame is so troublesome, why aren ’allt celebrities running away from it? The answer is thereare still ways to deal with it. Some stars stay calm by surrounding themselves with trusted friendsand family or by escaping to remote places away from big cities. They focus not on how famous theyare but on what they love to do or whatever made them famous in the first place.Sometimes a few celebrities can get a little justice. Still, even stars who enjoy full justice oftencomplain about how hard their lives are. They are tired of being famous already.63.It can be learned from the passage that stars today________.A. are often misunderstood by the publicB. can no longer have their privacy protectedC.spend too much on their public appearance D.care little about how they have come into fame64.What is the main idea of Paragraph 3?A. Great heroes of the past were generally admired.B. The problem faced by celebrities has a long history.C. Well-known actors are usually targets of tabloids.D. Works of popular writers often have a lot of readers.65. What makes it much harder to be a celebrity today?A. Availability of modern media.B. Inadequate social recognition.C. Lack of favorable chances.D. Huge population of fans.66. What is the author’ s attitude toward modern celebrity?A. Sincere.B. Skeptical.C. Disapproving.D. Sympathetic.DMultitaskingPeople who multitask all the time may be the worst at doing two things at once, a new researchsuggests. The findings, based on performances and self-evaluation by about 275 collegestudents, indicate that many people multitask not out of a desire to increase productivity, butbecause they are easily distracted ( 分心 ) and can ’ t focus on one activity. And“ those people turn out to be the worst at handling different things,Sanbonmatsu,”saidDavidpsychologist at theUniversity of Utah.Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking ( 追求刺激) or imperative ( 激动 ) they were. They then evaluated the participants ’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations whileremembering a set of letters.Not surprisingly, the scientists said, most people thought they were better than average atmultitasking, and those who thought they were better at it were more likely to report using acellphone while driving or viewing multiple kinds of media at once. But those who frequently dealwith many things at the same time were found to perform the worst at the actual multitasking test.They also were more likely to admit to sensation-seeking and impulsive behavior, which connectswith how easily people get bored and distracted.“ People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important . ” Sanbonmatsu said.Adam Gazzaley, a researcher at the University of California, San Francisco, who was not amember of the research group, said one limitation of the study was that it couldn ’findt outwhether people who start out less focused toward mul titasking or whether people’ s recognizingand understanding abilities change as a result of multitasking.The findings do suggest, however, why the sensation-seeker who multitask the most mayenjoy risky distracted driving.“ People who are multitaskinggenerallyareless sensitive to riskysituations.” said Paul Atchley, another researcher not in the group.“ This may partly explain people go in for these situations even though they’ re dangerous.”67.The research led by Sanbonmatsu indicates that people who multitask ________.A. seek high productivity constantlyB. prefer handling different things when getting boredC. are more focused when doing many things at a timeD. have the poorest results in doing various things at the same time68.When Sanbonmatsu and his colleagues conducted their research, they________.A. assessed the multitasking ability of the studentsB. evaluated the academic achievements of the studentsC. analyzed the effects of the participants’ tricky mental tasksD. measured the changes of the students’ understanding ability69.According to Sanbonmatsu, people multitask because of their________.A. limited power in calculationB. interests in doing things differentlyC. inability to concentrate on one taskD. impulsive desire to try new things70.From the last paragraph, we can learn that multitaskers usually________.A. drive very skillfullyB. go in for different tasksC. fail to react quickly to potential dangersD. refuse to explain the reasons for their behavior第二节（共 5 小题；每题 2 分。

北京师范大学考博英语试题及答案解析第一部分：试题Part 1 Listening Comprehension (15%)Part 11 Reading Comprehension (30%)Directions: Read the following passages carefully and then select the best answer from the four choices marked A,B,C, and D by marking the corresponding letter on the ANSWER SHEET with a single line through the center.1The fitness movement that began in the late 1960s and early 1970s centered around aerobic exercise (有氧操). Millions of individuals became engaged in a variety of aerobic activities, and literally thousands of health spas developed around the country to capitalize (获利) on this emerging interest in fitness, particularly aerobic dancing for females. A number of fitness spas existed prior to this aerobic fitness movement, even a national chain with spas in most major cities. However, their focus was not on aerobics, but rather on weight-training programs designed to develop muscular mass, strength, and endurance in their primarily male enthusiasts. These fitness spas did not seem to benefit financially form the aerobic fitness movement to better health, since medical opinion suggested that weight-training programs offered few, if any, health benefits. In recent years, however, weight training has again become increasingly popular for males and for females. Many current programs focus not only on developing muscular strength and endurance but on aerobic fitness as well.Historically, most physical-fitness tests have usually included measures of muscular strength and endurance, not for health-related reasons, but primarily because such fitness components have been related to performance in athletics. However, in recent years, evidence has shown that training programs designed primarily to improve muscular strength and endurance might also offer some health benefits as well. The American College of Sports Medicine now recommends that weight training be part of a total fitness program for healthy Americans. Increased participation in such training is one of the specific physical activity and fitness objectives of Healthy People 2000: National Health Promotion and Disease Prevention Objectives.16. The word “spas” (Line 3, Para. 1) most probably refers to _________.A) sports activitiesB) places for physical exerciseC) recreation centersD) athletic training programs17. Early fitness spas were intended mainly for __________.A) the promotion of aerobic exerciseB) endurance and muscular developmentC) the improvement of women’s figuresD) better performance in aerobic dancing18. What was the attitude of doctors towards weight training in health improvement?A) Positive.B) Indifferent.C) Negative.D) Cautious.19. People were given physical fitness tests in order to find out ________.A) how ell they could do in athleticsB) what their health condition was likeC) what kind of fitness center was suitable for themD) whether they were fit for aerobic exercise20. Recent studies have suggested that weight training __________.A) has become an essential part of people’s lifeB) may well affect the health of the traineesC) will attract more people in the days to comeD) contributes to health improvement as well2Fungi, of which there are over 100,000 species, including yeasts and othersingle-celled organisms as well as the common molds and mushrooms, were formerly classified as members of the plant kingdom, However, in reality they are very differentfrom paints and today they are placed in a separate group altogether, The principal reasonfor this is that none of there possesses chlorophyll, and since they cannot synthesize their own carbohydrates. They obtain their supplies either from the breakdown of dead organic matter or from other living organisms, Furthermore the walls of fungal cells are not madeof cellulose, as those of plants are, but of another complex sugar-like polymer called chitin the material from which the hard outer skeletons of shrimps, spiders, and insects are made. The difference between the chemical composition of the cell walls of fungi andthose of plants is of enormous importance because it enables the tips of the growing hyphac, the threadlike cells of the fungus, to secrete enzymes that break down the walls of plant cells without having any effect on those of the fungus itself It is thesecellulose-destroying enzymes that enable fungi to attack anything made from wood, wood pulp, cotton, flax, or other plant material.The destructive power of fungi is impressive, They are major cause of structure damage to building timbers, a cause of disease in animals and humans, and one of the greatest causes of agricultural losses. Entire crops can be wiped out by fungal attacks both before and after harvesting, Some fungi can grow at+50 oC , while others can grow at-50 oC , so even food in cold storage may not be completely safe from them, On the other hand,fung bring about the decomposition of dead organic matter, this enriching the soil and returning carbon dioxide to the atmosphere, They also enter into a number of mutually beneficial relationships with plants and other organisms In addition, lung are the sourceof marry of the most potent antibiotics used in clinical medicine, including penicillin21. What does paragraph one mainly discuss?A. differences between simple and complex fungiB. functions of chlorophyll in plantsC. functions of sugar in the walls of fungal cellsD. differences between fungi and plants22. Which of the following is mentioned as a major change in how scientists approach thestudy of fungi?A. Fungi are no longer classified as plants.B. Some single-celled organisms are no longer classified as fungiC. New methods of species identification have been introducedD. Theories about the chemical composition of fungi have been revised.23. The skeletons of shrimps, spiders and insects are mentioned in paragraph one because they______.A. can be destroyed by fungiB. have unusual chemical compositionsC. contain a material found in the walls of fungal cellsD. secrete the same enzymes as the walls of fungal cells do24. Fungi have all the following characteristics EXCEPT _______.A. They grow hyphacB. They secrete enzymesC. They synthezise celluloseD. They destroy crops25. The passage mentions “penicillin”(last line) as an example of _______.A. a medicine derived from plantsB. a beneficial use of fungiC. a product of theD. a type of fungi that grows at extreme temperatures3By far the most important United States export product in the 18 th and 19th centurieswas cotton favored by the European textile over flax or wool because it was easyto process and soft to touch. Mechanization of spinning and waving allowed significant centralization and expansion in the textile industry during this period and at the same timethe demand for cotton increased dramatically. American producers were able to meet this demand largely because of the invention of the coition gin by Eli Whitey in 1793. Cottoncould be grown throughout the South, but separating the fiber—or lint—from the seed wasa laborious process. Sea island cotton was relatively easy to process by hand, because itsfibers were long and seeds were concentrated at the base of the flower, but is demandedlong growing season, available only along the nation’s casterm seacoast .Short-staplecotton required a much shorter growing season, but the shortness of the fibers and theirmixture with seeds meant that a worker could hand-process only about one pound per day Whitney’s gin was a hand-powered machine with revolving drums and metal teeth to pull Cotton fibers away from seeds . Using the gin, a worker could produce up to SO percents ofLint a day The later development of larger gins powered by horses, water or streamMultiplied productivity furtherThe interaction of improved processing and high demand led to a rapid spread of thecultivation of cotton and to a surge in production. It became the main American export dwarfing all others. In 1802 cotton composed 14 percent of total American exports by value Cotton had a 36 percent share by 1810 and over 50 percent share in 1830. In 1860 61 percent of the value of American exports was represented by cotton.In contrast, wheat and wheat flour composed only 6 percent of the value of American exports in that year Clearly, cotton was king in the trade of the young republic. The growing market for cotton and other American agricultural products led to an unprecedented expansion of agricultural settlement, mostly in the eastern half of the United States—west of the Appalachian Mountains and east of the Mississippi River.26. The main point of the passage is that the 18th and 19th centuries were a time when _________.A. the European textile industry increased its demand for American export productsB. Cotton became the most important American export productC. Cotton became a profitable crop but was still time-consuming to processD. Mechanization for spinning and weaving dramatically changed the textile industry27. All of the following are mentioned in the passage as reasons for the increased demand for cotton EXCPPT______.A. cotton’s softnessB. cotton’s case of processingC. a shortage of flax and woolD. the growth that occurred in the textile industry28. According to the passage, one advantage of Sea island cotton was its _______.A. abundance of seedsB. adaptability to different climatesC. long growing seasonD. long fibers29. Which of the following can be inferred from the passage about cotton-production in the United States after the introduction of Whitney’s cotton gin?A. More cotton come from Sea Inland cotton plants than before.B. More cotton came from short-staple cotton plants than beforeC. Most cotton produced was sold domestically.D. Most cotton produced was exported to England.30. According to the passage, the Mississippi River was ______.A. one of the boundaries of a region where new agricultural settlement took placeB. a major source of water for agricultural cropsC. the primary route by which agricultural crops were transportedD. a main source of power for most agricultural machinery4Why do some new products succeed, bringing millions of dollars to innovatingCompanies, while others fail, often with great losses? The answer is not simple, and certainly we cannot say that “good”products succeed while “bad”products fail Many products that function well and seen to meet consumer needs have fallen by the wayside Sometimes, virtually identical products exist in the market at the same time with one emerging as profitable while the other fails, MeNeal Laboratories Tylenol has become successful as an aspirin substitute, yet Bristol-Meyers entered the lest market at about the same time with Neotrent, also a substitute for aspirin, which quickly failedThe nature of the product is a factor in its success of failure, but the important point is the consumer’s perception of the products need-satisfying capability, Any new product conception should be aimed at meeting a customer need, and the introductory promotion should seek to communicate that need-satisfying quality and motivate the customer to try may be soughtHere the company walks a tightrope A new product is more likely to be successful if it represents a truly novel way of solving a customer problem but this very newness, if carried too far, may ask the customer to team new behavior patterns, The customer willmake the change if the perceived benefit is sufficient but inertia is strong and customerswill often not go to the effort that is required, During the late sixties and early seventies Bristol-Meyers met with new product failures that exemplify both of these problems, In1967 and 1968 the company entered the market with a $5 million advertising campaignfor Fact toothpaste, and an $11 million campaign to prorate Resolve, Both productsfailed quickly, not because they didn’t work or because there was no construer need but apparently because consumers just could see no reason to shift from an alreadysatisfactory product to a different one that promised no new benefit.31. The first sentence of the first paragraph is a question to which the answer is ________.A. that the good products succeed while the bad failB. that the “good”are not really good but the “bad”are actually bad.C. that new products will succeed if they function well and fail if they don’tD. not given in the paragraph32. What are Tylenol and Neotrend?A. They are names of twp drug manufacturers.B. They are probably two new brands of medicine which serve as a substitute for aspirinC. Tylenol is a drug manufacturer whereas Neotrend is a new substitute medicine for aspirin.D. They are probably the names of chemists who invented the new medicine33. The success or failure of a product seems to be determined by a number of factors, one of which the author emphasizes is the customer’s perception of the product’s ______.A. quality and priceB. usefulness and durabilityC. need-satisfying capabilityD. appearance and inner packing34. What does the author mean when be says “the company walks a tightrope’(Sentence 1, paragraph 3)?A. The company has both the chance to succeed and to fail in dealing in a new productB.

An Angel at My Table, so extraordinary”Also contributing to the film’s success was Campion’s ability to induce fine performances from her character, ‘She directs actors differently from anyone I’ve ever known ,”SamNeil told Paul Freeman in an interview for the Chicago Tribute “I always felt that therewas a big safety net under her and that I was permitted to take as many risks as I wantedto “Genevieve Lemon, who had played the title role in Sweetie and took the supportingrole of Nessie in The Piano, agreed Campion is already at work on her next project an adaptation of Henry Jaures’s novel The Portrait of a lady.36. The passage is primarily concerned with _______.A. presenting the interrelationships between Campion’s three moviesB. commenting on Jane Campion as a filmmaker and her recent movie, The PianoC. explaining why The Plano was a successD. criticizing Jane Campion and her three movies37. According to the passage, Campion’s three movies share which of the following characteristics?A. All of them seem to be quite commonplace at first glance.B. All of them deal with stories that took place in New Zealand.C. All of them describe a woman who is rebellious against the traditional view of femaleD. Each movie minors the time when the movie was produced.38. It can be concluded that Campion is regarded as one of the most talented filmmakers in recent years because _______.A. the movie that has brought such great honor to her is just the third feature she has producedB. she is only 40 years oldC. she is the first woman who has received such honorsD. she began her movie production from her student days39. It can be inferred from the passage that Campion’s directing style of the hird movie_________.A. is a simple combination of those in her two early moviesB. contributed greatly to the success of the movieC. is much of an imitation of previous onesD. is quite creative40. The author implies that Campion is different from other filmmakers in that_______.A. she is especially good at making the actors perform to the best of their abilityB. she is quite able to assure the actors of their successC. she tends to encourage the actors to take as many risks as possibleD. she always places a big safety net under the actors when directing the movies6Speech—the act of uttering sounds to convey meaning is a kind of human actionLike any other constantly repeated action, speaking has to be learned but once it isLearned, it becomes a generally unconscious and apparently automatic process.As far as we can determine human beings do not need to be forced to speak mostBabies born to possess a sort of instinctive drive to produce speechlike noises How tospeak and what to say are another matter altogether, These actions are learned from the particular society into which the baby is born; so that, like all conduct that is learned froma society—from the people around us—speech is a pattered activity.The meandering babble and chatter of a young child are eventually channeled by imitation into a few orderly grooves that represent the pattern accepted as meaningful bythe people around him. Similarly, a child’s indiscriminate practice of putting things intohis mouth becomes limited to putting food into his mouth in a certain way.The sounds that a child can make are more varied and numerous than the sounds thatany particular language utilizes, However, a child born into a society with a pattern oflanguage is encouraged to make a small selection of sounds and to make these few sounds over and over until it is natural for him to make these sounds and no others.41. For an adult the process of speaking usually involves________.A. conscious selection of soundsB. imitation of those around himC. a drive to make noisesD. unconscious actions42. The selection says that most babies have an instinctive drive to ______.A. express ideas in wordsB. make speechliks noisesC. convey meaningD. imitate sounds around them43. Conduct that is learned from a society may be called________.A. instinctive driveB. selectionC. automatic activityD. patterned activity44. The most important factor in a child’s learning to speak probably is _____.A. repetitionB. selectionC. instinctD. imitation45. The sounds that a child is able to make are _____.A. not as varied as those used in languageB. more varied and numerous than those in any languageC. far fewer than those needed to form a languageD. completely different from the sounds of languagePart III Translation and Writing (55%)Section A Translation (40%)Translate the following into Chinese1) He was taken to the huge medieval fortress at the harbour’s mouth, He found prison life fairly endurable His cell was darup and dark, and the food was bud and insufficient; but his sister soon obtained permission to seed him all the necessaries of life from borne He was kept in solitary confinement and failed to obtain any explanation of the cause of his arrest Nevertheless the tranquil frame of mind in which he had entered the fortress did not change Not being allowed books, he spent his time in prayer and devout meditation, and waited without impatience for the further course of events.2) Industrial engineering involves the application of engineering principles and techniques of scientific management to the maintenance of a high level of productivity at optimum cost in industrial enterprises, In the 1880s F.

Playing ―action‖ video games improves a visual ability __51__ tasks like reading and driving at night, a new study says. The ability, called contrast sensitivity function, allows people to discern even subtle changes __52__ gray against a uniformly colored backdrop. It’s also one of the first visual aptitudes to fade with age. __53__ a regular regimen of action video game training can provide long-lasting visual power, according to work led by Daphne Bavelier of the University of Rochester.Previous research shows that gaming improves other visual skills, such as the ability to track several objects at the same time and __54__ attention to a series of fast-moving events. Bavelier said, ―A lot of different aspects of the visual system are being enhanced, __55__.‖The new work suggests that playing video games could someday become part of vision-correction treatments, which currently rely mainly on surgery or corrective lenses. ―__56__ you’ve had eye surgery or get corrective lenses, exposing yourself to these games should help the optical system to recover faster and better, you need to retrain the brain to make use of the better, crisper information that’s coming in __57__ your improved eyesight,‖ Bavelier said.Expert action gamers in the study played first-person shooters Unreal Tournament 2004 and Call of Duty 2. A group of experienced nonaction gamers played The Sims 2, a ―life simulation‖ video game. The players of nonaction video games didn’t see the same vision __58__, the study says. Bavelier and others are now trying to figure out exactly why action games __59__ seem to sharpen visual skill. It may be that locating enemies and aiming accurately is a strenuous, strength-building workout for the eyes, she said. Another possible __60__ is that the unpredictable, fast-changing environment of the typical action game requires players to constantly monitor entire landscapes and analyze optical data quickly. 51.

A. benefitsB. defectsC. approachesD. risks59. A. in caseB. in advanceC. in returnD. in particular60. A. effectB. reasonC. outcomeD. conclusionPart IV Reading Comprehension (30%)Directions:In this part there are six passages, each of which is followed by five questions. For each question there are four possible answers marked A, B,C, and D. Choose the best answer and mark the letter of your choice onthe ANSWER SHEET.Passage oneThere is plenty we don’t know about criminal behavior. Most crime goes unreported so it is hard to pick out trends from the data, and even reliable sets of statistics can be difficult to compare. But here is one thing we do know: those with a biological predisposition to violent behavior who are brought up in abusive homes are very likely to become lifelong criminals.Antisocial and criminal behavior tends to run in families, but no one was sure whether this was due mostly to social-environmental factors or biological ones. It turns out both are important, but the effect is most dramatic when they act together. This has been illustrated in several studies over the past six years which found that male victims of child abuse are several times as likely to become criminals and abusers themselves if they were born with a less-active version of a gene for the enzyme monoamine oxidase A (MAO-A), which breaks down neurotransmitters crucial to the regulation of aggression.Researchers recently made another key observation: kids with this ―double whammy‖ of predisposition and an unfortunate upbringing are likely to show signs of what’s to come at a very early age. The risk factors for long-term criminality –attention deficit hyperactivity disorder, low IQ, language difficulties – can be spotted in kindergarten. So given what we now know, should n’t we be doing everything to protect the children most at risk?No one is suggesting testing all boys to see which variant of the MAO-A gene they have, but what the science is telling us is that we should redouble efforts to tackle abusive upbringings, and even simple neglect. This will help any child, but especially those whose biology makes them vulnerable. Thankfully there is already considerable enthusiasm in both the US and the UK for converting the latest in behavioral science into parenting and social skills: both governments have schemes in place to improve parenting in families where children are at risk of receiving poor care.Some people are uncomfortable with the idea of early intervention because it implies our behavior becomes ―set‖ as we grow up, compromising the idea of free will. That view is understandable, but it would be negligent to ignore what the studies are telling us. Indeed, the cost to society of failing to intervene －in terms of criminal damage, dealing with offenders and helping victims of crime －is bound to be greater than the cost of improving parenting. The value to the children is immeasurable.61. Researchers have come to a consensus: to explain violent behavior ________.A. in terms of physical environmentB. form a biological perspectiveC. based on the empirical dataD. in a statistical way62. When we say that antisocial and criminal behavior tends to run in families, asindicated by the recent findings, we can probably mean that ___________.A. a particular gene is passed on in familiesB. child abuse will lead to domestic violenceC. the male victims of child abuse will pass on the tendencyD. the violent predisposition is exclusively born of child abuse63. The recent observation implicated that to check the development of antisocialand criminal behavior ___________.A. boys are to be screened for the biological predispositionB. high-risk kids should be brought up in kindergartenC. it is important to spot the genes for the risk factorsD. active measures ought to be taken at an early age64. To defend the argument against the unfavorable idea, the author makes it apoint to consider ___________.A. the immeasurable value of the genetic research on behaviorB. the consequences of compromising democracyC. the huge cost of improving parenting skillsD. the greater cost of failing to intervene65. Which of the following can be the best title for the passage?A. Parenting Strategies for KidsB. The Making of a CriminalC. Parental EducationD. Abusive ParentingPassage twoAfter 25 years battling the mother of all viruses, have we finally got the measure of HIV? Three developments featured in this issue collectively give grounds for optimism that would have been scarcely believable a year ago in the wake of another failed vaccine and continuing problems supplying drugs to all who need them.Perhaps the most compelling hope lies in the apparent ―cure‖ of a man with HIV who had also developed leukemia. Doctors treated his leukemia with a bone marrow transplant that also vanquished the virus. Now US Company Sangamo Biosciences is hoping to emulate the effect patients being cured with a single shot of gene therapy, instead of taking antiretroviral drugs for life.Antiretroviral therapy (ART) is itself another reason for optimism. Researchers at the World Health Organization have calculated that HIV could be effectively eradicated in Africa and other hard-hit places using existing drugs. The trick is to test everyone often, and give those who test positive ART as soon as possible. Because the drugs rapidly reduce circulating levels of the virus to almost zero, it would stop people passing it on through sex. By blocking the cycle of infection in this way, the virus could be virtually eradicated by 2050.Bankrolling such a long-term program would cost serious money –initially around $3.5 billion a year in South Africa alone, ring to $85 billion in total. Huge as it sounds, however, it is peanuts compared with the estimated $1.9 trillion cost of the Iraq war, or the $700 billion spent in one go propping up the US banking sector. It also look small beer compared with the costs of carrying on as usual, which the WHO says can only lead to spiraling cases and costs.The final bit of good news is that the cost of ART could keep on falling. Last Friday, GlaxoSmithKline chairman Andrew Witty said that his company would offer all its medicines to the poorest countries for at least 25 per cent less than the typical price in rich countries. GSK has already been doing this for ART, but the hope is that the company may now offer it cheaper still and that other firms will follow their lead.No one doubt the devastation caused by AIDS. In 2007, 2 million people died and 2.7 million more contracted the virus. Those dismal numbers are not going to turn around soon – and they won’t turn around at all without huge effort and investment. But at least there is renewed belief that, given the time and money, we can finally start riddling the world of this most fearsome of viruses.66. Which is the following can be most probably perceived beyond the first paragraph?A. The end of the world.B. A candle of hope.C. A Nobel prize.D. A Quick Fix.67. According to the passage, the apparent “cure” of the HIV patient who had alsodeveloped leukemia would ___________.A. make a promising transition from antiretroviral medication to gene therapyB. facilitate the development of effective vaccines for the infectionC. compel people to draw an analogy between AIDS and leukemiaD. would change the way we look at those with AIDS68. As another bit of good news, ___________.A. HIV will be virtually wiped out first in AfricaB. the cycle of HIV infection can be broken with ARTC. the circulating levels of HIV have been limited to almost zeroD. the existing HIV drugs will be enhanced to be more effective in 25 years69. The last reason for optimism is that ___________.A. governments will invest more in improving ARTB. the cost of antiretroviral therapy is on the declineC. everybody can afford antiretroviral therapy in the worldD. the financial support of ART is coming to be no problem70. The whole passage carries a tone of ___________.A. idealismB. activismC. criticismD. optimismPassage ThreeArchaeology can tell us plenty about how humans looked and the way they lived tens of thousands of years ago. But what about the deeper questions? Could early humans speak, were they capable of self-conscious reflection, did they believe in anything?Such questions might seem to be beyond the scope of science. Not so. Answering them is the focus of a burgeoning field that brings together archaeology and neuroscience. It aims to chart the development of human cognitive powers. This is not easy to do. A skull gives no indication of whether its owner was capable of speech, for example. The task then is to find proxies (替代物)for key traits and behaviors that have stayed intact over millennia.Perhaps the most intriguing aspect of this endeavor is teasing out the role of culture as a force in the evolution of our mental skills. For decades, development of the brain has been seen as exclusively biological. But increasingly, that is being challenged.Take what the Cambridge archaeologist Colin Renfrew calls ―the sapient (智人的) paradox (矛盾)‖. Evidence suggests that the human genome, and hence the brain, has changed little in the past 60,000 years. Yet it wasn’t until about 10,000 years ago that profound changes took place in human behavior: people settled in villages and built shrines. Renfrew’s paradox is why, if the hardware was in place, did it take so long for humans to start changing the world?His answer is that the software –the culture –took a long time to develop. In particular, the intervening time saw humans vest (赋予) meaning in objects and symbols. Those meanings were developed by social interaction over successive generations,passed on through teaching, and stored in the neuronal connections of children.Culture also changes biology by modifying natural selection, sometimes in surprising ways. How is it, for example, that a human gene for making essential vitamin C became blocked by junk DNA? One answer is that our ancestors started eating fruit, so the pressure to make vitamin C ―relaxed‖ and the gene became unnecessary. By this reasoning, early humans then became addicted to fruit, and any gene that helped them to find it was selected for.Evidence suggests that the brain is so plastic that, like genes, it can be changed by relaxing selection pressure. Our understanding of human cognitive development is still fragmented and confused, however. We have lots of proposed causes and effects, and hypotheses to explain them. Yet the potential pay-off makes answers worth searching for. If we know where the human mind came from and what changed it, perhaps we can gauge where it is going. Finding those answers will take all the ingenuity the modern human mind can muster.71. The questions presented in the first paragraph ___________.A. seem to have no answers whateverB. are intended to dig for ancient human mindsC. are not scientific enough to be answered hereD. are raised to explore the evolution of human appearance72. The scientists find the proxy to be ___________.A. the role of cultureB. the passage of timeC. the structure of a skullD. the biological makeup of the brain73. According to Renfrew’s paradox, the transition from 60,000 to 10,000 years agosuggests that ___________.A. human civilization came too lateB. the hardware retained biologically staticC. it took so long for the software to evolveD. there existed an interaction between gene and environment74. From the example illustrating the relation between culture and biology, wemight conclude that ___________.A. the mental development has not been exclusively biologicalB. the brain and culture have not developed at the same paceC. the theory of natural selection applies to human evolutionD. vitamin C contributes to the development of the brain75. Speaking of the human mind, the author would say that ___________.A. its cognitive development is extremely slowB. to know its past is to understand its futureC. its biological evolution is hard to predictD. as the brain develops, so as the mindPassage FourDespite the numerous warnings about extreme weather, rising sea levels and mass extinctions, one message seems to have got lost in the debate about the impact of climate change. A warmer world won’t just be inconvenient. Huge swathes (片) of it, including most of Europe, the US and Australia as well as all of Africa and China will actually be uninhabitable--- too hot, dry or stormy to sustain a human population.This is no mirage. It could materialize if the world warms by an average of just 4°C, which some models predict could happen as soon as 2050. This is the world our children and grandchildren are going to have to live in. So what are we going to do about it?One option is to start planning to move the at-risk human population to parts of the world where it will still be cool and wet. It might seem like a drastic move, but this thought experiment is not about scaremongering (危言耸听). Every scenario is extrapolated from predictions of the latest climate models, and some say that 4°C may actually turn out to be a conservative estimate.Clearly this glacier-free, desertified world---with its human population packed into high-rise cities closer to the poles---would be a last resort. Aside from anything else, it is far from being the most practical option: any attempt at mass migration is likely to fuel wars, political power struggles and infighting.So what are the alternatives? The most obvious answer is to radically reduce carbon dioxide levels now, by fast-tracking green technologies and urgently implementing energy-efficient measures. But the changes aren’t coming nearly quickly enough and global emissions are still rising. As a result, many scientists are now turning to ―Earth’s plan B‖.Plan B involves making sure we have large scale geoengineering technologies ready and waiting to either suck CO2 out of the atmosphere or deflect the sun’s heat. Most climate scientists were once firmly against fiddling with the Earth’s thermostat, fearing that it may make a bad situation even worse, or provide politicians with an excuse to sit on their hands and do nothing.Now they reluctantly acknowledge the sad truth that we haven’t managed to reorder the world fast enough to reduce CO2 emissions and that perhaps, given enough funding research and political muscle, we can indeed design, test and regulate geoengineering projects in time to avert the more horrifying consequences of climate change.Whatever we do, now is the time to act. The alternative is to plan for a hothouse world that none of us would recognize as home.76. To begin with, the author is trying to remind us of ____________.A. the likelihood of climate change making life inconvenientB. the warning against worsening climate changeC. the inevitable consequence of global warmingD. the misconception of a warmer world77. As the thought experiment shows, those at risk from global warming will ____________.A. live with the temperature raised by an average of 4°CB. have nowhere to go but live in the desertC. become victims as soon as 2050D. move closer to the poles78. It is clear from the passage that a practical approach to global warming is _________.A. to reduce massively CO2 emissionsB. to take protective measures by 2025C. to prepare a blueprint for mass migrationsD. to launch habitual constructions closer to the poles。
