Choose the best one and mark your answer on the ANSER SHEET. Passage 1 The human ear contains the organ for hearing and the organ for balance. Both organs involve fluid-filled channels containing hair cells that produce electrochemical impulses when the hairs are stimulated by moving fluid. The ear can be divided into three regions: outer, middle, and inner. The outer ear collects sound waves and directs them to the eardrum separating the outer ear from the middle ear. The middle ear conducts sound vibrations through three small bones to the inner ear. The inner ear is a network of channels containing fluid that moves in response to sound or movement. To perform the function of hearing, the ear converts the energy of pressure waves moving through the air into nerve impulses that the brain perceives as sound. Vibrating objects, such as the vocal cords of a speaking person, create waves in the surrounding air. These waves cause the eardrum to vibrate with the same frequency. The three bones of the middle ear amplify and transmit the vibrations to the oval window, a membrane on the surface of the cochlea, the organ of hearing. Vibrations of the oval window produce pressure waves in the fluid inside the cochlea. Hair cells in the cochlea convert the energy of the vibrating fluid into impulses that travel along the auditory nerve to the brain. The organ for balance is also located in the inner ear. Sensations related to body position are generated much like sensations of sound. Hair cells in the inner ear respond to changes in head position with respect to gravity and movement. Gravity is always pulling down on the hairs, sending a constant series of impulses to the brain.

Part I Reading ComprehensionSection A (50%)Directions: There are five passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked a),b),c) and d).You should decide on the best choice and circle the letter on the ANSWER SHEET.Passage OneQuestions 1 to 5 are based on the following passage.31. Money-laundering (洗钱) has been one of the world’s fastest-growing industries over decade despite increasing efforts by the world’s financial authorities to stamp it out. Following is a simple guide to the world of money-laundering.Money-laundering is the process by which money obtained by illegal means is given the appearance of legitimate income and returned into circulation. The word and practice are widely believed to have been invented by the US Mafia (黑手党). As a means of mixing the dirty cash obtained from prostitution, gambling, gun-running, blackmail and its other wicked activities, so that it came out more or less clean, the Mafia bought up and operated large numbers of Laundromats (自助洗衣点). As good cash businesses they were a good means of providing the appearance of honest cash flow.Various techniques can be employed and the means of money-laundering, but they essentially boil down to three stages. Step one: moving the money from the scene of the crime A to a remote location B, ideally in another country, preferably a bank account, if possible one that is anonymous. Step two: disguising the trail leading from A to B. Step three: making the cash available to the criminals, along with a plausible explanation of how ti came legally into their possession.Apart from harming the economies that it feeds off, the money-laundering industry is essential to organized crime. As the head of the UN’s crime-fighting wing Pino Arlacchi remarked, organized crime “brutalizes society and diminishes respect for the value like honesty and cooperation upon which successful societies are based”. Or as a senior US official said in 1999, “money-laundering may look like a polite form of white-collar crime, but it is the companion of brutality, deceit and corruption.”The liberalization of markets around the world and deregulation(解除管制) of exchange controls are regarded ad the chief causes of the rapid expansion of money-laundering over the past decade. Together they have opened up many more channels for laundering dirty money and provided more opportunities to hide its origins. UN officials believe the most important single measure in eliminating money-laundering is the ending of bank secrecy.1. We know from the passage that money-laundering .a) has almost been stamped out by the world’s financial authorities.b) has greatly promoted the development of the world’s industries.c) only has a ten-year history but has grown rapidly.d) has expanded rapidly over the past decade.2. Which of the following is closest in meaning to the phrase “stamp it out” (para.1) in the first paragraph?a) To put an end to it completely.b) To mark a sign by pressing on it.c) To announce it illegal.d) To do harm to is.3. The reason why the Mafia bought up and ran substantial Laundromats is that .a) the Mafia can carry out large numbers of illegal transactions in them.b) the Mafia has many wicked activities like prostitution and gambling in them.c) the Laundromats can give the dirty cash the appearance of legitimate income.d) the Laundromats is such a profit-making industry that it has attracted the Mafia.4. In money-laundering, money would be moved from the scene of the crime to .a) the financial authoritiesb) the circulation fields.c) Laundromats operated by the Mafia.d) anonymous bank account in another country.5. With the worldwide liberalization of markets, money-laundering has expanded rapidly by .a) deregulating the exchange controls.b) buying and operating more Laundromats.c) having more channels to launder dirty money.d) tightening the bank secrecy rules.Passage TwoQuestions 6 to 10 are based on the following passage.The media can impact current events. As a graduate student at Berkeley in the 1960s, I remember experiencing the events related to the People’s Park that wore occurring on campus. Some of these events were given national media coverage in the press and on TV. I found it interesting to compare my impressions of what was going on with perceptions obtained from the news media. I could begin to see events of that time feed on news coverage. This also provided me with some healthy insights into the distinctions between these realities.Electronic media are having a greater impact on the people’s lives every day. People gather more and more of their impressions from representations. Television and telephone communications are linking people to global village, or what one writer calls the electronic city.Consider the information that television brings into your home every day. Consider also the contact you have with others simply by using telephone. These media extend your consciousness and your contact. For example, thevideo coverage of the 1989 San Francisco earthquake focused on “live action” such as the fires or the rescue efforts. This gave the viewer the impression of total disaster. Television coverage of the Iraqi War also developed an immediacy. CNN reported events as they happened. This coverage was distributed worldwide. Although most people were far away from these events, they developed some perception of these realities.In 1992, many people watched in horror as riots broke out on a sad Wednesday evening in Los Angeles, seemingly fed by video coverage from helicopters. This events was triggered by the verdict (裁定) in the Rodney King beating. 32. We are now in an age where the public can have access to information that enables it to make its own judgments, and most peoples, who had seen the video of this beating, could not understand how the jury was able to acquit (宣布无罪) the policemen involved . Media coverage of events as they occur also provides powerful feedback that influences events. This can have harmful results, as is seemed on that Wednesday night in Los Angeles. By Friday night the public got to see Rodney King on television pleading, “Can we all get along?” By Saturday, television seemed to provide positive feedback as the Los Angeles riot turned out into a rally for peace. The television showed thousands of people marching with banners and cleaning tools. Because of that, many more people turned out to join the peaceful event they saw unfolding on television. The real healing, of course, will take much longer, but electronic media will continue to be a part of that process.6. Where is the passage most likely to be from?a) Textbook of Media.b) Thesis.c) Newspaper or Magazine.d) Speech.7. The 1989 San Francisco earthquake was mentioned to show .a) how damaging the earthquake was.b) how people carried out rescue workc) the electronic media extend your consciousness and your contact.d) the viewers’ impression of total disaster.8. The term “ electronic city”( para.2) refers to .a) Los Angelesb) San Franciscoc) Berkeleyd) Earth9. The 1992 Los Angeles riots broke out because .a) the jury acquitted the policemen who had beaten Rodney King.b) people can make their own judgments.c) video coverage from helicopters had made people angry.d) video coverage had provided powerful feedback.10. It can be inferred from the passage that .a) media coverage of events as they occur can have either good of bad results.b) most people who had seen the video of the Rodney King beating agree withthe verdict of jury.c) the 1992 Los Angeles riots lasted a whole week.d) Rodney King seemed very angry when he appeared on television on Friday. Passage ThreeQuestions 11 to 15 are based on the following passage.Recent research has claimed that an excess of positive ions(离子) in the air can have an ill effect on people’s physical or psychological health. What are positive ions? Well, the air is full of ions, electrically charged particle, and generally there is a rough balance between the positive and the negative charged. But sometimes this balance becomes disturbed and a large proportion of positive ions are found. This happens naturally before thunderstorms, earthquakes of when winds such as the mistral(寒冷的西北风) are blowing in certain countries. Or it can be caused by a build-up of static electricity(静电) indoors from carpets or clothing made of man-made fibers, or from TV sets, duplicators or computer display screens.When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue, irritability, and some particularly sensitive people suffer nausea(恶心) or even mental disturbance. Animals are also found to be affected, particularly before earthquakes. Snakes have been observed to come out of hibernation, rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California.Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these are near the sea, close to waterfalls of fountains ,or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effort of a holiday by the sea, or in the mountains with tumbling streams or waterfalls.33. To increase the supply of negative irons indoors, some scientists recommend the use of ionizers: small portable machines which generate negative ions. They claim that ionizers not only clean and refresh the air but also improve the health of people of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds observing the effects on themselves, or on others, of a negative rich or poor environment. After all, it is debatable whether depending on seismic(地震的) readings to anticipate earthquakes is more effective than watching the cat.11. What effect does excessive positive ionization have on some people?a) They think they are insane.b) They feel rather bad-tempered.c) They become violently sick.d) They are too tired to do anything.12. According to the passage, static electricity can be caused by .a) using home-made electrical goods.b) wearing clothes made of natural materials.c) waling on artificial floor coverings.d) copying TV programs on a computer.13. A high negative ion count is likely to be found .a) near a pond with a water pump.b) close to slow flowing riverc) in some barren mountains.d) by a rotating water sprinkler.14. What kind of machine can generate negative ions indoors?a) Ionizers.b) Air-conditioners.c) Exhaust-fansd) Vacuum-pump15. Some scientists believe that .a) watching animals to anticipate earthquakes is more effectiveb) the unusual behaviors of animals can not be trustedc ) neither watching nor using seismograph is reliabled) earthquakes cannot affect any animalsPassage FourQuestions 16to 20 are based on the following passage.Joseph Weizenbaum, professor of computer science at MIT, thinks that the sense of power over the machine ultimately corrupts the computer hacker and makes him into a not very desirable sort of programmer. 34.The hackers are so involved with designing their program, making it more and more complex and bending it to their will, that they don’t bother trying to make it understandable to other users. They rarely keep records of their programs for the benefit of others, and they rarely take time to understand why a problem occurred.Computer science teachers say they can usually pick out the prospective hackers in their courses because these students make their homework assignments more complex than they need to be. Rather than using the simplest and most direct method, they take joy in adding extra steps just to prove their ingenuity.But perhaps those hackers know something that we don’t know about the shape of things to come. “That hacker who had to be literally dragged off his chair at MIT is now a multimillionaire of the computer industry,”says MIT professor Michael Dertouzos. “And two former hackers became the founders of the highly successfulApple home computer company.”When seen in this light, the hacker phenomenon may not be so strange after all. If, as many psychiatrists say, play is really the basis for all human activity, then the hacker games are really the preparation for future developments. Sherry Turkle, a professor of sociology at MIT, has for years been studying the way computers fit into people’s lives. She points out that the computer, because it seems to us to be so “intelligent”, so “capable”, so “human”, affects the way we think about ourselves and our ideas about what we are. She says that computers and computer toys already play an important role in children’s efforts to develop an identity by allowing them to test ideas about what is alive and what is not.“The youngsters can form as many subtle nuances(细微差距) and textured relationships with the computers as they can with people.” Turkle points out.16. The passage tells about .a) the strange behavior of the computer hackersb) the ultimate importance of bringing up computer hackersc) different opinions concerning the hacker phenomenond) the emergence of computer hackers17. According to Prof.Weizenbaum, what led to the hackers’ strange behavior isa) their strong desire to control the computerb) their ignorance of the responsibility of a programmerc) their incompetence in making new computer programsd) their deliberate attempts to make their programs complex and impracticable18. In Prof. Dertouzos’ opinion, we know that .a) computer industry will certainly make multimillionaires of the hackersb) the hackers are likely to be very successful businessmenc) the hackers probably have better insight into the future than other peopled) only a few hackers will be successful in their later life19. The phrase“to develop an identity”(Para.4) means .a) to become distinguishedb) to seek an answerc) to build up a creative abilityd) to form a habit20. The passage tries to convey to its readers the idea that .a) perhaps the hacker phenomenon is not bad at allb) though the hackers are in fact playing with the computer, there may be somebenefitsc) the computer hackers are the hope of the computer industry of tomorrowd) the computer hackers could be useful if under proper guidancePassage FiveQuestions 21 to 25 are based on the following passage.The value of a business increasingly lies not in physical and financial assets that are on the balance sheet, but in intangibles: brands, patents, franchises, software, research programs, ideas and expertise. Few firms try to measure returns on these assets, let alone publish information on them. Yet they are often what underlies a firm’s success. “Our primary assets, which are our software and our software-development skills, do not show up on the balance sheet at all,”says Microsoft’s boss, Bill Gates. “This is probably not very enlightening from a purely accounting point of view.”A sign that companies do not measure their assets properly may be the growing gap between their stock-market value and the book value of their assets. Between 1973 and 1993, the median ratio of market values to book values of American public companies doubles; the difference has grown with a boom in high-tech shares. The gap is biggest for companies that have most rapidly boosted spending on research and development(R&D). Even within industries, the divergence(分歧) between stock-market returns and reported earnings has increased.You might think this would present a problem for investors, who no linger have a good way of telling whether the market value of a company is soundly based. Yet investors seem to know instinctively that knowledge is valuable. 35. A study has found that the share price of American multinationals that spend heavily on R&D rises when they buy foreign subsidiaries, but it falls when a multinational with low R&D spending buys abroad. Presumably investors understand that companies in knowledge-based businesses can exploit the magic of rising returns to scale. Once a pill or a software program is developed, each extra sale brings in more money at little extra cost: the bigger the market, the greater the profits.In fact, the absence of good measures may bother those who run firms more than those who invest in them. For managers, the big problem is how to judge rates of return. With building a factory, there are time-honored methods for calculating the payback. But what if you are investing in R&D or software, or deciding whether to buy better people or to train more? There aren’t tools for making such decisions.21. The intangibles of a company are reflected in .a) physical and financial assetsb) stock-market valuec) the balance sheetd) the difference between the stock-market value and the book value22. What can we infer about Microsoft?a) It has no book-value assets.b) Its stock-market value equals its book value.c) There’s a great gap between its stock-market value and book value.d) Its stock-market value does not reflect the company’s real value23. Why does the share price of American multinationals rise?a) Because they buy foreign subsidiariesb) Because they invest much in intangible assets.c) Because they have low R&D spendingd) Because the investors know the methods for calculating the payback ofknowledge-based businesses24. An investor who buys stocks of a company in knowledge-based businesses baseshis decision on .a) pure speculation(投机)b) the company’s book valuec) whether the company buys foreign subsidiariesd) the prospect that its research will translate into low cost products25. The phrase “such decisions”(Para.4) refers to .a) running firms in knowledge-based businessesb) investing in firms in knowledge-based businessesc) judging rates of return on firms in knowledge-based businessesd) calculating returns on a newly-built factorySection BDirections:In the following article, some sentences have been removed. For Questions 26~30, choose the most suitable one from the list A~G to fit into each of the numbered blank. There are two extra choices, which do not fit in any of the gaps.

Mice and beetles ay eat your floor so that you drop in to the flat below for an uninvited cup of tea.26. .You cannot always prevent disasters, but you can insure against them. Most forms of insurance are voluntar y-it is up to you whether you take out a policy or not. But some forms are compulsory. 27. .The “parties” to an agreement, or contract, are the individuals or groups concerned. With third-party motor insurance, the three parties are (i) you yourself, (ii) your insurance company, and (iii) anybody else---for example, the man whose Jaguar has just smashed up your Mini. Third –party insurance does not cover fire, theft or anything else. It is intended only to protect road users from each other. 28. .Another form of compulsory insurance is National Insurance. Everybody over 16 earning money on a regular basis must pay a sum each week to the state. These weekly contributions cover part of the cost of the National Health Service and the other social service benefits, e.g. unemployment benefits, sickness benefits, old-age pensions, industrial injury benefits and so on. You must be able to prove you have paid your contributions, so you must have a card(kept by your employer unless you are self-employed) onto which stamps are stuck every week. Of course, you can take out private health insurance as well if you wish, but you must still pay your state contributions.There are, of course, many insurance companies in Britain, both large andsmall. But there is also a rather special organization called Lloyd’s, which started as a coffee-house in late 17th century. Lloyd’s is a society of around six thousand members-all of them underwriters-and is administered by a committee controlled by Act of Parliament.29. .You have to go to an insurance broker who will then contact a member of Lloyd’s for you. If you want to insure something expensive---like a fleet of Jumbo jets, for example-your broker will probably have to contact a syndicate of underwriters because the risks would be too high for one man to cover.Lloyd’s will probably insure you against any risk at all---provided you are prepared to pay the premiums.30. .Maybe clowns insure their noses. You never know-anything may happen.A.Professional pianists sometimes insure their hands.B.Insurance on the other hand eliminates risks already in existence and , bycombining them, substitutes a small known loss(premium) contributed by each person insured.C.If you drive a car, for example, you must take out a third-party insurance policy.D.So it is not an insurance company in the normal sense, but an insurance marketand you cannot do business with it directly.E.If you want to insure against all the other terrible things that might happen to youor your car, you can take out a comprehensive policy.F.This spreading of risk protects the individual against losses that may be disastrousif he has to bear them alone.G.Anything may happen, you never know.Part II TranslationSection ADirections: Translate the following five sentences(all of which are underlined sentences in the five reading passages in Section A, Part I.) into Chinese.

2014年北京师范大学博士入学英语试题与答案详解

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.

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2005年博士生入学考试英语试题Part I.Listening Comprehension(20 points) (略)part II.Reading Comprehension (25 points)Directions:There are five 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 oneA weather map is an important tool for geographers.A succession of three or four maps present a continuous picture of weather changes.Weather forecasters are able to determine the speed of air masses and fronts; to determine whether an individual pressure area is deepening or becoming shallow and whether a front is increasing or decreasing in intensity.They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving.Thus.a most significant function of the map is to reveal a synoptic picture of conditions in the atmosphere at a given time.All students of geography should be able to interpret a weather map accurately.Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area.They reveal in a few minutes what otherwise would take hours to describe.The United States Weather Bureau issues information about approaching storms,floods,fronts,droughts,and all climatic conditions in general.Twice a month it issues a 30-day“outlook’’which is a rough guide to weather conditions likely to occur over broad areas of the United States.These 30-day outlooks are based upon an analysis of the upper air level which often set the stage for the development of air masses,fronts and storms.Considerable effort is being exerted today to achieve more accurate weather predictions.With the use of electronic instruments and earth satellites,enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations.Extensive experiments are also in progress for weather modification studies.:21. One characteristic of weather maps NOT mentioned by the author in this passage is _____A.fronts B.changes in temperature C.frost D.wind speed22.The 30-day forecast is determined by examining________.A.daily weather mapsC.satellite reportsB.upper air levelsD.changing fronts23.The observation of weather conditions by satellites is advantageous because it___A. is modern and profitable for the companies involvedB. uses electronic instruments to measure the weather on a daily basisC. enables man to easily alter the weather to his advantage and profitD. gives the scientists information not obtained readily otherwise24. At the present time,experiments are being conducted in_____A. manipulating weatherB .determining density of pressure groupsC. satellitesD. controlling storms25.A weather map is synoptic because it_______A. summarizes a great deal of informationB. appears dailyC. shows changing frontsD. can be interpreted accuratelyPassage twoWith only about 1,000 Pandas left in the world,China is desperately trying to clone the animal and save the endangered species.That‟s a move similar to what a Texas A&M University researcher has been undertaking for the past five years in a project called“Noah‟s Ark”.D r-Duane Kraemer, a professor in Texas A&M‟s College of Veterinary Medicine and a pioneer in embryo transfer work and related procedures.said he salutes the Chinese effort and“I wish them a11 the best success possible.It‟s a worthwhile project, certainly not all easy one,and it‟s very much like what we’re attempting here at Texas A&M—to save animals from extinction.”Noah‟s Ark is aimed at collecting eggs,embryos,semen and DNA of endangered animals.and storing them in liquid nitrogen.If certain species should become extinct,Kraemer says there would be enough of the basic building blocks to reintroduce the species in the future.It is estimated that as many as 2,000 species of mammals,birds and reptiles will become extinct over the next 1 00 years.The panda,native only to China,is in danger of becoming extinct in the next 25 years.This week,Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit.They are now trying to implant the embryo into a host animal.The entire procedure could take from three to five years to complete.“The nuclear transfer of one species to another i s not easy, and the lack of available panda eggs could be a major problem,”Kraemer believes.“They will probably have to do several hundred transfers to result in one pregnancy.It takes a long time and it's difficult,but this could be groundbreaking science if it works.They are certainly not putting ally 1ive pandas at risk,So it is worth the effort,”adds Kraemer, who is one of the leaders of the Missyplicity Project at Texas A&M,the first-ever attempt at cloning a dog.“They are trying to do something that’s never been done.and this is very similar to our work in Noah‟s Ark.We’re both trying to save animals that face extinction.I certainly applaud their effort and there‟s a lot we can learn from what they areattempting to do.It‟s a research that is very much needed.”26. The aim of ……Noah‟s Ark‟‟ project is to_____A. salute the Chinese efforts in saving pandasB. implant embryo into a host animal 、C. introduce cells from a dead female panda into the egg cells of a Japanese white rabbitD. save endangered animals from extinction27.How long will the Chinese panda—cloning project take according to the passage? A.3 to 5 years.B.1 year.C.25 years.D.2 years.28 .The word “groundbreaking”(Paragraph 7)can be interpreted as____A. pioneeringB. epoch-makingC. essentially newD.evolutionary29.What could be the major problem in cloning pandas according to Professor Kraemer?A.Lack of host animals.B.Lack of available panda eggs.C。

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.1Imagine 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 States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food 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 ofthose 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 sa y 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 their products 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.21. 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 delicious22.

Their numbers probably total in the tens of billions. Bats also vary considerably in size-from the tiny Philippine bamboo bat, with a six-inch wingspan and weighing 1/20th of an ounce to the “flying fox” with a wingspan of four or five feet and weight of two pounds.The diet of bats is varied. Most types eat insects, but they also consume blood, pollen, and nectar and fruits. Some eat other vertebrates (animals with backbones) such as fish, lizards, and even other bats. Those that feed on flowers very often server as the primary pollinator of the flowers. The insect-consuming forms, quite obviously, are very beneficial.Perhaps the most unusual characteristic of bats is their skilled nocturnal flying ability. This skill is so highly developed that they are capable of avoiding obstacles even in total darkness. Bats possess a high degree of tactile sense that may help them in avoiding obstacles, but their primary ability to do so is based on their ability to make high-pitched sounds and on their acute hearing ability.Flying bats were long thought to be silent creatures, but this is now known not to be the case. While in flight, bats are continuously emitting a series of ultrasonic orientation pulses that are inaudible to the human ear. The frequency of the cries of bats, at 50,000 vibrations per second, is estimated to be two and half times higher than the human ear can hear.This unique operation, a highly refined type of sonar system, allows the bat to detect rebounding pulses from obstacles near and far in its environment. They system is unique, additionally, in that the bat is capable of sorting through numerous rebounding pulses so as to avoid objects in its immediate path. Rescarchers are attempting to understand this system in hopes that it may reveal how the human brain processes sensory information.In the final analysis bats are interesting and amazing; and to contrast to popular legends, they are quite useful and helpful to nature and man.26. Which of the following is true?A. There are more rodents in the world than bats.B. There are more bats in the world than rodents.C. Bats are usually bigger than rodents.D. Rodents are usually bigger than bats.27. According to the passage, some bats eat .A. human-beingsB. rodentsC. foxesD. other bats28. The word “nocturnal” in P aragraph 3 is related to .A. soundB. vibrationsC. nightD. reputation29. What can make bats avoid objects in flight?A. Their sharp sense of hearing.B. Their ability to emit ultrasonic sounds.C. Their unique sense of seeing.D. Both A and B.30. We can conclude from the passage that bats are .A. really more intelligent than manB. often wronged in popular legendsC. ugly and dangerousD. beautiful in appearance3There were two widely divergent influences on the early development of statistical methods. Statistics had a mother who was dedicated to keeping orderly records of governmental units (“state” and “statistics” come from the same Latin root, “status&rdquo and a gentlemanly gambling father who relied on mathematics to increase his skill at playing the odds in games of chance. The influence of the mother on the offspring, statistics, is represented by counting, measuring, describing, tabulating, ordering, and the taking of censuses—all of which led to modern descriptive statistics. From the influence of the father came modern inferential statistics, which is based squarely on theories of probability.Descriptive statistics involves tabulating, depicting, and describing collections of data. Theses data may be quantitative, such as measures of height, intelligence, or grade level—variables that are characterized by an underlying continuum—or the data may represent qualitative variables, such as ***, college major, or personality type. Large masses of data must generally undergo a process of summarization or reduction before they are comprehensible. Descriptive statistics is a tool for describing or summarizing or reducing to comprehensible form the properties of an otherwise unwieldy mass of data.Inferential statistics is a formalized body of methods for solving another class of problems that present great difficulties for the unaided human mind. This general class of problems characteristically involves attempts to make predictions using a sample of observations. For example, a school superintendent wishes to determine the proportion of children in a large school system who come to school without breakfast, have been vaccinated for flu, or whatever. Having a little knowledge of statistics, the superintendent would know that it is unnecessary and inefficient to question eachchild: the proportion for the entire district could be estimated fairly accurately from a sample of as few as 100 children. Thus, the purpose of inferential statistics is to predict or estimate characteristics of a population from a knowledge of the characteristics of only a sample of the population.31. The word “divergent” (Para. 1, Line 1) is closest in meaning to .A. distributedB. differentC. recordedD. prominent32. According to the first paragraph, counting and census-taking are associatedwith .A. inferential statisticsB. qualitative changesC. descriptive statisticsD. unknown variables33. Why does the author mention the “mother” and “father” in the passage?A. To point out that parents can teach their children statistics.B. To introduce inferential statistics.C. To explain that there are different kinds of variables.D. To present the background of statistics in a humorous and understandable way.34. Which of the following statements about descriptive statistics is best supported by the passage?A. It reduces large amount of data to a more comprehensible form.B. It is based on probability.C. It can be used by people with little knowledge of mathematics.D. It measures only qualitative differences.35. With what is the passage mainly concerned?A. The drawbacks of descriptive and inferential statistics.B. The development and use of statistics.C. Applications of inferential statistics.D. How to use descriptive statistics.4It is possible to persuade mankind to live without war? War is an ancient institution which has existed for at least six thousand years. It was always wicked and usually foolish, but in the past the human race managed to live with it. Modern ingenuity has changed this. Either Man will abolish war, or war will abolish Man. For the present, it is nuclear weapons that cause the gravest danger, but bacteriological or chemical weapons may, before long, offer an even greater threat. If we succeed in abolishing nuclear weapons, our work will not be done. It will never be done until we have succeeded in abolishing war. To do this, we need to persuade mankind to look upon international questions in a new way, not as contests of force, in which the victory goes to the side which is most skillful in massacre, but by arbitration inaccordance with agreed principles of law. It is not easy to change age-old mental habits, but this is what must be attempted.There are those who say that the adoption of this or that ideology would prevent war. I believe this to be a profound error. All ideologies are based upon dogmatic assertions which are, at best, doubtful, and at worst, totally false. Their adherents believe in them so fanatically that they are willing to go to war in support of them.The movement of world opinion during the past two years has been very largely such as we can welcome. It has become a commonplace that nuclear war must be avoided. Of course very difficult problems remain in the international sphere, but the spirit in which they are being approached is a better one than it was some years ago. It has began to be though, even by the powerful men who decide whether we shall live or die, that negotiations should reach agreements even if both sides do not find these agreements wholly satisfactory. It has begun to be understood that the important conflict nowadays is not between East and West, but between Man and the H-bomb.36. This passage implies that war is now .A. more wicked than in the pastB. as wicked as in the pastC. less wicked than in the pastD. what people try to live with37. According to the author .A. it is impossible to live without warB. war is the only way to suede international disagreementsC. war must be abolished if man wants to surviveD. war will be abolished by modern ingenuity38. The author says that modern weapons .A. will help abolish warB. put mankind in grave dangerC. will gradually become part of man’s lifeD. need further improving39. The author believes that the only way to abolish war is to .A. abolish nuclear weaponsB. let the stronger side take over the worldC. improve bacteriological and chemical weaponsD. settle international issues through negotiation40. The last paragraph suggests that .A. nuclear war will definitely not take placeB. international agreements are now reached more and more easilyC. man is beginning to realize that nuclear war is his greatest enemyD. world opinion is in favour of nuclear war5The acknowledged “King of Ragtime” was the black pianist and composer Scott Joplin. Joplin (1868-1917), originally from Texarkana, Texas, began his career as an itinerant pianist. By 1885 he was in St. Louis, playing in honky-tonks and sporting houses. He went to Chicago briefly (1893) to try his luck in the entertainment halls that had sprung up around the Word’s Fair, then in 1894 to Sedalia, Missouri, to stay until the turn of the century. His first published rag, Original Rags, came out in March, 1899; later the same year appeared Maple Leaf Rag, named for a saloon and dance hall in Sedalia. The work has an instant and resounding success, and by the time of his death Joplin had published more than thirty original rags, and other piano pieces, songs, and arrangements. He had even larger aims: in 1902 he finished a ballet score called Rag Time Dance, and in 1903 the opera A Guest of Honor, unpublished and now apparently lost, in 1911 came another opera, Treemonisha. The artistic success of these larger works is debatable, but that of Joplin’s piano rags is not; they can only be described as elegant, varied, often subtle, and as sharply incised as a cameo. They are the precise American equivalent, in terms of a native style of dance music, of minuets by Mozart, mazurkas by Chopin, or waltzes by Brahams. They can both be lovely and powerful, infectious and moving-depending, of course, on the skill and stylishness of the pianist, for they are not easy music technically and they demand a clean but “swinging” performance.41. Which of the following is the best title for the passage?A. Scott Joplin’s Early CareerB. Rare Piano Works of Scott JoplinC. Sedalia: The Birthplace of RagtimeD. A Ragtime composer and His Music42. It can be inferred from the passage that Joplin is recognized as the “King of Ragtime” because he .A. was probably the greatest composer of ragtime musicB. began his career as a famous child pianistC. created the character “King of Ragtime” in one of his operasD. was a descendant of a European royal family43. According to the passage, which of the following is an accurate statement about Maple Leaf Rag?A. It was Joplin’s favorite composition.B. Its name came from an establishment in Missouri.C. It was published in March 1899.D. Its popularity grew slowly.44. Toward the end of the passage, the author refers to the works of other composers in order to illustrate the .A. popularity of different styles of dance music of recent centuriesB. success of Joplin’s operas in EuropeC. high quality of Joplin’s work as an American musical formD. powerful move ment attributed to Joplin’s compositions45. From the last sentence of the passage, one may infer that Joplin’s piano music can best be appreciated when played .A. by a highly skilled pianistB. in an elegant settingC. with a moving classical styleD. for a small audienceⅢ.?Translation and Writing (55 points)Part A TranslationTranslate the following into Chinese (30 points):1. We care for literature primarily on account of its deep and lasting human significance. A great book grows directly out of life; in reading it, we are brought into large, close, and fresh relations with life; and in that fact lies the final explanation of its power. Literature is a vital record of what men have seen in life, what they experienced of it, what they have though and felt about those aspects of it which have the most immediate and enduring interest for all of us. It is thus fundamentally an expression of life through the medium of language. Such expression is fashioned into the various forms of literary art. But it is important to understand, to begin with, that literature lives by virtue of the life it embodies. By remembering this, we shall be saved from the besetting danger of confusing the study of literature with the study of philology, rhetoric, and even literary technique.2. Physical science is the systematic study of the inorganic world, as distinguished from the study of the organic world, which is the province of biological science. Physical science is ordinarily though of as consisting of four broad areas: astronomy, physics, chemistry, and the Earth sciences. Physics is the basic physical science. It deals with the structure and behaviour of individual atoms and their components, as well as with the different forces of nature and their relationships. It also is concerned with the physical properties of matter and with such phenomena as electricity and magnetism. Chemistry focuses on the properties and reactions of molecules. Broadly speaking, it tends to concentrate on the specific properties of different elements and compounds, as opposed to physics which is chiefly concerned with the general properties of matter as a whole. Astronomy entails the study of the entire universe beyond the Earth. It includes investigations of the gross physical properties of the earth primarily as they relate to interactions with other components of the solar system. Most other aspects are dealt with by the Earth sciences. Translate the following into English (10 points):在20世纪,我们习惯于于使用无线电,它成了每个人生活的一部分.人们在汽车上,在家里,在海滩上—几乎在所有的地方听无线电。

北京师范大学考博英语翻译试题及其解析Investigators of monkey’s social behavior have always been struckby monkeys’aggressive potential and the consequent need for socialcontrol of their aggressive behavior.Studies directed at describingaggressive behavior and the situations that elicit it,as well as thesocial mechanisms that control it,were therefore among the firstinvestigations of monkeys’social behavior.Investigators initially believed that monkeys would compete forany resource in the environment:hungry monkeys would fight over food,thirsty monkeys would fight over water,and,in general,at time morethan one monkey in a group sought the same incentive simultaneously,a dispute would result and would be resolved through some form ofaggression.However,the motivating force of competition for Geng duoyuan xiao wan zheng kao bo ying yu zhen ti ji qi jie xi qing lian xiquan guo mian fei zi xun dian hua:si ling ling liu liu ba liu jiuqi ba,huo jia zi xun qq:qi qi er liu qi ba wu san qi incentives beganto be doubted when experiments like Southwick’s on the reduction ofspace or the withholding of food failed to produce more than temporaryincreases in intragroup aggression.Indeed,food deprivation not onlyfailed to increase aggression but in some cases actually resulted indecreased frequencies of aggression.Studies of animals in the wild under conditions of extreme fooddeprivation likewise revealed that starving monkeys devoted almostall available energy to foraging,with little energy remaining foraggressive interaction.Furthermore,accumulating evidence fromlater studies of a variety of primate groups,for example,the study conducted by Bernstein,indicates that one of the most potent stimuli for eliciting aggression is the introduction of an intruder into an organized group.Such introductions result in far more serious aggression than that produced in any other types of experiments contrived to produce competition.These studies of intruders suggest that adult members of the same species introduced to one another for the first time show considerable hostility because,in the absence of a social order,one must be established to control interanimal relationships.When a single new animal is introduced into an existing social organization,the newcomer meets even more serious aggression.Whereas in the first case aggression establishes a social order,in the second case resident animals mob the intruder,thereby initially excluding the new animal from the existing social unit.The simultaneous introduction of several animals lessens the effect,if only because the group divides its attention among the multiple targets.If,however,the several animals introduced a group constitute their own social unit,each group may fight the opposing group as a unit;but,again,no individual is subjected to mass attack,and the very cohesion of the groups precludes prolonged individual combat.The submission of the defeated group,rather than unleashing unchecked aggression on the part of the victorious group,reduces both the intensity and frequency of further attack.Monkey groups therefore seem to be organized primarily tomaintain their established social order rather than to engage in hostilities per se.1.The author of the text is primarily concerned with[A]advancing a new methodology for changing a monkey’s social behavior.[B]comparing the methods of several research studies on aggression among monkeys.[C]explaining the reasons for researcher’s interest in monkey’s social behavior.[D]discussing the development of investigators’theories about aggression among monkeys.2.Which of the following best summarizes the findings reported in the text about the effects of food deprivation on monkeys’behavior?[A]Food deprivation has no effect on aggression among monkeys.[B]Food deprivation increases aggression among monkeys because one of the most potent stimuli for eliciting aggression is the competition for incentives.[C]Food deprivation may increase long-term aggression among monkeys in a laboratory setting,but it produces only temporary increase among monkeys in the wild.[D]Food deprivation may temporarily increase aggression among monkeys,but it also leads to a decrease in conflict.3.The text suggests that investigators of monkeys’socialbehavior have been especially interested in aggressive behavior among monkeys because[A]aggression is the most common social behavior among monkeys.[B]successful competition for incentives determines the social order in a monkey group.[C]situation that elicit aggressive behavior can be studied in a laboratory.[D]most monkeys are potentially aggressive,yet they live in social units that could not function without control of their aggressive impulses.4.The text supplies information to answer which of the following questions?[A]How does the reduction of space affect intragroup aggression among monkeys in an experimental setting?[B]Do family units within a monkey social group compete with other family units for food?[C]What are the mechanisms by which the social order of an established group of monkeys controls aggression within that group?[D]How do monkeys engaged in aggression with other monkeys signal submission?5.Which of the following best describes the organization of the second paragraph?[A]A hypothesis is explained and counter evidence is described.[B]A theory is advanced and specific evidence supporting it iscited.[C]Field observations are described and a conclusion about their significance is drawn.[D]Two

2015年北京师范大学考博英语真题试卷(总分68, 做题时间90分钟)1. Reading ComprehensionThe human ear contains the organ for hearing and the organ for balance. Both organs involve fluid-filled channels containing hair cells that produce electrochemical impulses when the hairs are stimulated by moving fluid. The ear can be divided into three regions: outer, middle, and inner. The outer ear collects sound waves and directs them to the eardrum separating the outer ear from the middle ear. The middle ear conducts sound vibrations through three small bones to the inner ear. The inner ear is a network of channels containing fluid that moves in response to sound or movement. To perform the function of hearing, the ear converts the energy of pressure waves moving through the air into nerve impulses that me brain perceives as sound. Vibrating objects, such as the vocal cords of a speaking person, create waves in me surrounding air. These waves cause the eardrum to vibrate with the same frequency. The three bones of the middle ear amplify and transmit the vibrations to the oval window, a membrane on the surface of the cochlea, the organ of hearing. Vibrations of me oval window produce pressure waves in the fluid inside me cochlea. Hair cells in the cochlea convert the energy of the vibrating fluid into impulses that travel along the auditory nerve to the brain. The organ for balance is also located in the inner ear. Sensations related to body position are generated much like sensations of sound. Hair cells in the inner ear respond to changes in head position with respect to gravity and movement. Gravity is always pulling down on the hairs, sending a constant series of impulses to the brain. When the position of the head changes—as when the head bends forward—the force on the hair cells changes its output of nerve impulses. The brain then interprets these changes to determine the head's new position.1.What can be inferred about the organs for hearing and balance?A Both organs evolved in humans at the same time.B Both organs send nerve impulses to the brain.C Both organs contain the same amount of fluid.D Both organs are located in me ear's middle region.2.Hearing involves all of the following EXCEPT______.A motion of the vocal cords so that they vibrateB stimulation of hair cells in fluid-filled channelsC amplification of sound vibrationsD conversion of wave energy into nerve impulses3.It can be inferred from Paragraphs 2 and 3 that the cochlea is a part of______.A the outer earB me eardrumC the middle earD the inner ear4.What can be inferred from Paragraph 4 about gravity?A Gravity has an essential role in the sense of balance.B The ear converts gravity into sound waves in the air.C Gravity is a force that originates in the human ear.D The organ for hearing is not subject to gravity.5.In this passage, the author mainly explains______.A the organs of the human earB the function of the hearingC the three regions of the earD how the ear organ performs the hearing and balanceThe geology of the Earth's surface is dominated by the particular properties of water. Present on Earth in solid, liquid, and gaseous states, water is exceptionally reactive. It dissolves, transports, and precipitates many chemical compounds and is constantly modifying the face of the Earth. Evaporated from the oceans, water vapor forms clouds, some of which are transported by wind over the continents. Condensation from the clouds provides the essential agent of continental erosion: rain. Precipitated onto the ground, the water trickles down to form brooks, streams, and rivers, constituting what is called the hydrographic network. This immense polarized network channels the water toward a single receptacle: an ocean. Gravity dominates this entire step in the cycle because water tends to minimize its potential energy by running from high altitudes toward the reference point that is sea level. The rate at which a molecule of water passes through the cycle is not random but is a measure of the relative size of the various reservoirs. If we define residence time as the average time for a water molecule to pass through one of the three reservoirs—atmosphere, continent, and ocean—we see that the times are very different. A water molecule stays, on an average, eleven days in the atmosphere, one hundred years on a continent and forty thousand years in the ocean. This last figure shows the importance of the ocean as the principal reservoir of the hydrosphere but also the rapidity of water transport on the continents. A vast chemical separation process takes places during the flow of water over the continents. Soluble ions such as calcium, sodium, potassium, and some magnesium are dissolved and transported. Insoluble ions such as aluminum, iron, and silicon stay where they are and form the thin, fertile skin of soil on which vegetation can grow. Sometimes soils are destroyed and transported mechanically during flooding. The erosion of the continents thus results from twoclosely linked and interdependent processes, chemical erosion and mechanical erosion. Their respective interactions and efficiency depend on different factors.6.According to the passage, clouds are primarily formed by water______.A precipitating onto the groundB changing from a solid to a liquid stateC evaporating from the oceansD being carried by wind7.The passage suggests that the purpose of the "hydrographic network" is to______.A determine the size of molecules of waterB prevent soil erosion caused by floodingC move water from the Earth's surface to the oceansD regulate the rate of water flow from streams and rivers8.What determines the rate at which a molecule of water moves through the cycle, as discussed in the third paragraph?A The potential energy contained in water.B The effects of atmospheric pressure on chemical compounds.C The amounts of rainfall that fall on the continents.D The relative size of the water storage areas.9.All of the following are examples of soluble ions EXCEPT______.A magnesiumB ironC potassiumD calcium10.The word "efficiency" in line 21 is closest in meaning to______.A relationshipB growthC influenceD effectivenessScientists have long understood that supermassive black holes weighing millions or billions of suns can tear apart stars that come too close. The black hotels gravity pulls harder on the nearest part of the star, an imbalance that pulls the star apart over a period of minutes or hours, once it gets close enough. Scientists say this uneven pulling is not the only hazard facing the star. The strain of these unbalanced forces can also trigger a nuclear explosion powerful enough to destroy the star from within. Matthieu Brassart and Jean-Pierre Luminet of the Observatoire de Paris in Meudon, France, carried out computer simulationsof the final moments of such an unfortunate star's life, as it veered towards a supermassive black hole. When the star gets close enough, the uneven forces flatten it into a pancake shape. Some previous studies had suggested this flattening would increase the density and temperature inside the star enough to trigger intense nuclear reactions that would tear it apart. But other studies had suggested that the picture would be complicated by shock waves generated during the flattening process and that no nuclear explosion should occur. The new simulations investigated the effects of shock waves in detail, and found that even when their effects are included, the conditions favor a nuclear explosion. " There will be an explosion of the star — it will be completely destroyed," Brassart says. Although the explosion obliterates the star, it saves some of the star's matter from being devoured by the black hole. The explosion is powerful enough to hurl much of the star's matter out of the black hole's reach, he says. The devouring of stars by black holes may already have been observed, although at a much later stage. It is thought mat several months after the event that rips the star apart, its matter starts swirling into the hole itself. It heats up as it does so, releasing ultraviolet light and X-rays. If stars disrupted near black holes really do explode, then they could in principle allow these events to be detected at a much earlier stage, says Jules Hatpern of Columbia University in New York, US2. "It may make it possible to see the disruption of that star immediately if it gets hot enough," he says. Brassart agrees. "Perhaps it can be observed in the X-rays and gamma rays, but it's something that needs to be more studied," he says. Supernova researcher Chris Fryer of the Los Alamos National Laboratory in Los Alamos, New Mexico, US3, says the deaths of these stars are difficult to simulate, and he is not sure whether the researchers have proven their case that they explode in the process.11.Something destructive could happen to a star that gets too close to a black hole. Which of the following destructive statements is NOT mentioned in the passage?A The black hole could tear apart the star.B The black hole could trigger a nuclear explosion in the star.C The black hole could dwindle its size considerably.D The black hole could devour the star.12.According to the third paragraph, researchers differed from each other in the problem of ______.A whether nuclear reaction would occurB whether the stars would increase its density and temperatureC whether shock waves would occurD whether the uneven forces would flatten the stars13.According to the fourth paragraph, which of the following is NOT true?A No nuclear explosion would be triggered inside the star.B The star would be destroyed completely.C Much of the star's matter thrown by the explosion would be beyond the black hole's reach.D The black hole would completely devour the star.14.What will happen several months after the explosion of the star?A The star's matter will move further away from by the black hole.B The black hole's matter will heat up.C The torn star's matter will swirl into the black hole.D The black hole's matter will release ultraviolet light and X-rays.15.According to the context, the word "disruption" in Paragraph 6means______.A confusionB tearing apartC interruptionD flatteningOur culture has caused most Americans to assume not only that our languageis universal but that the gestures we use are understood by everyone. Wedo not realize that waving good-bye is the way to summon a person from the Philippines to one's side, or that in Italy and some Latin-American countries, curling the finger to oneself is a sign of farewell. Those private citizens who sent packages to our troops occupying Germany after World War II and marked them GIFT to escape duty payments did not botherto find out that " Gift" means poison in German. Moreover, we like to thinkof ourselves as friendly, yet we prefer to be at least 3 feet or an arm's length away from others. Latins and Middle Easterners like to come closer and touch, which makes Americans uncomfortable. Our linguistic and cultural blindness and the casualness with which we take notice of the developed tastes, gestures, customs and languages of other countries, are making us lose friends, business and respect in the world. Even herein the United States, we make few concessions to the needs of foreign visitors. There are no information signs in four languages on our public buildings or monuments; we do not have multilingual guided tours. Very few restaurant menus have translations, and multilingual waiters, bank clerks and policemen are rare. Our transportation systems have maps in English only and often we ourselves have difficulty understanding them. When we go abroad, we tend to cluster in hotels and restaurants where English is spoken. Then attitudes and information we pick up are conditioned by those natives—usually the richer—who speak English. Our business dealings, as well as the nation's diplomacy, are conductedthrough interpreters. For many years, America and Americans could get by with cultural blindness and linguistic ignorance. After all America is the most powerful country of the free world, the distributor needed funds and goods. But all that is past. American dollars no longer buy all good things, and we are slowly beginning to realize that our proper role in the world is changing. A 1979 Harris poll reported that 55 percent of Americans want this country to play a more significant role in world affairs; we want to have a hand in the important decisions of the next century, even though it may not always be the upper hand.16.It can be inferred that Americans being approached too closely by Middle Easterners would most probably______.A stand stillB jump asideC step forwardD draw back17.The author gives many examples to criticize Americans for their______.A cultural self-centerednessB casual mannersC indifference towards foreign visitorsD arrogance towards other countries18.In countries other than their own most Americans______.A are isolated by the local peopleB are not well informed due to the language barrierC tend to get along well with the nativesD need interpreters in hotels and restaurants19.According to the author, Americans' cultural blindness and linguistic ignorance will______.A affect their image in the new eraB cut themselves off from the outside worldC limit their role in world affairsD weaken the position of the US dollar20.The author's intention in writing this article is to make Americans realize that______.A it is dangerous to ignore their foreign friendsB it is important to maintain their leading role in world affairsC it is necessary to use several languages in public placesD it is time to get acquainted with other culturesHistorians have only recently begun to note the increase in demand for luxury goods and services that took place in 18th-century England.McKendrick has explored the Wedgwood firm's remarkable success in marketing luxury pottery; Plumb has written about the proliferation of provincial theaters, musical festivals, and children's toys and books. While the fact of this consumer revolution is hardly in doubt, three key questions remain: Who were the consumers? What were their motives? And what were the effects of the new demand for luxuries? An answer to the first of these has been difficult to obtain. Although it has been possible to infer from the goods and services actually produced what manufactures and servicing trades thought their customers wanted, only a study of relevant personal documents written by actual consumers will provide a precise picture of who wanted what. We still need to know how large this consumer market was and how far down the social scale the consumer demand for luxury goods penetrated. With regard to this last question, we might note in passing that Thompson, while rightly restoring laboring people to the stage of 18th-century English history, has probably exaggerated the opposition of these people to the inroads of capitalist consumerism in general; for example, laboring people in eighteenth-century England readily shifted from home-brewed beer to standardized beer produced by huge, heavily capitalized urban breweries. To answer the question of why consumers became so eager to buy, some historians have pointed to the ability of manufacturers to advertise in a relatively uncensored press. This, however, hardly seems a sufficient answer. McKendrick favors a Veblen model of conspicuous consumption stimulated by competition for status. The "middling sort" bought goods and services because they wanted to follow fashions set by the rich. Again, we may wonder whether this explanation is sufficient. Do not people enjoy buying things as a form of self-gratification? If so, consumerism could be seen as a product of the rise of new concepts of individualism and materialism(a preoccupation with or stress upon material rather than intellectual or spiritual things), but not necessarily of the frenzy for conspicuous competition. Finally, what were the consequences of this consumer demand for luxuries? McKendrick claims that it goes a long way toward explaining the coming of the Industrial Revolution. But does it? What, for example, does the production of high-quality pottery and toys have to do with the development of iron manufacture or textile mills? It is perfectly possible to have the psychology and reality of a consumer society without a heavy industrial sector. That future exploration of these key questions is undoubtedly necessary should not, however, diminish the force of the conclusion of recent studies: the insatiable demand in eighteenth-century England for frivolous as well as useful goods and services foreshadows our own world.21.In the first paragraph, the author mentions McKendrick and Plumb most probably in order to ______.A contrast their views on the subject of luxury consumerism in18th-century EnglandB indicate the inadequacy of historiographical approaches to 18th-century English historyC give examples of historians who have helped to establish the fact of growing consumerism in 18th-century EnglandD support the contention that key questions about 18th-century consumerism remain to be answered22.Which of the following items, if preserved from 18th-century England, would provide an example of the kind of documents mentioned in lines 3-4, Paragraph 2?A A written agreement between a supplier of raw materials and a supplier of luxury goods.B A diary that mentions luxury goods and services purchased by its author.C A theater ticket stamped with the date and name of a particular play.D A payroll record from a company that produced luxury goods such as pottery.23.According to the text, Thompson attributes to laboring people in18th-century England which of the following attitudes toward capitalist consumerism?A Enthusiasm.B Curiosity.C Ambivalence.D Hostility.24.In the third paragraph, the author is primarily concerned with______.A contrasting two theses and offering a compromiseB questioning two explanations and proposing a possible alternative to themC paraphrasing the work of two historians and questioning their assumptionsD examining two theories and endorsing one over the other25.According to the text, 18th-century England and the contemporary world of the text readers are______.A dissimilar in the extent to which luxury consumerism could be said to be widespread among the social classesB dissimilar in their definitions of luxury goods and servicesC dissimilar in the extent to which luxury goods could be said to be stimulant of industrial developmentD similar in their strong demand for a variety of goods and servicesPity those who aspire to put the initials PhD after their names. After16 years of closely supervised education, prospective doctors of philosophy are left more or less alone to write the equivalent of a large book. Most social-science postgraduates have still not completed their theses by the time their grant runs out after three years. They must then get a job and finish in their spare time, which can often take a further three years. By then, most new doctors are sick to death of the narrowly defined subject which has blighted their holidays and ruined their evenings. The Economic and Social Research Council, which gives grantsto postgraduate social scientists, wants to get better value for moneyby cutting short this agony. It would like to see faster completion rates; until recently, only about 25% of PhD candidates were finishing within four years. The ESRC's response has been to stop PhD grants to all institutions where the proportion taking less than four years is below 10% ; in the first year of this policy the national average shot up to 39%. The ESRC feels vindicated in its toughness, and will progressively raise the threshold to 40% in two years. Unless completion rates improve further, this would exclude 55 out of 73 universities and polytechnics — including Oxford University, the London School of Economics and the London Business School. Predictably, howls of protest have come from the universities, who view the blacklisting of whole institutions as arbitrary and negative. They point out that many of the best students go quickly into jobs where they can apply their research skills, but consequently take longer to finis their theses. Polytechnics with as fewas two PhD candidates complain that they are penalized by random fluctuations in student performance. The colleges say there is no hard evidence to prove that faster completion rates result from greater efficiency rather than lower standards or less ambitious doctoral topics. The ESRC thinks it might not be a bad thing if PhD students were more modestin their aims. It would prefer to see more systematic teaching of research skills and fewer unrealistic expectations placed on young men and women who are undertaking their first piece of serious research. So in futureits grants will be given only where it is convinced that students are being trained as researchers, rather than carrying out purely knowledge-based studies. The ESRC can not dictate the standard of thesis required by external examiners, or force departments to give graduates more teaching time. The most it can do is to try to persuade universities to change their ways. Recalcitrant professors should note that students want more research training and a less elaborate style of thesis, too.26.By time new doctors get a job and try to finish their theses in spare time,______.A most of them died of some sicknessB their holidays and evenings have been ruined by their jobsC most of them are completely tired of the narrowly defined subjectD most of their grants run out27.Oxford University would be excluded out of those universities that receive PhD grants from ESRC, because the completion rate of its PhD students' theses within four years is lower than ______.A 25%B 40%C 39%D 10%28.All the following statements are the arguments against ESRC's policy EXCEPT______.A all the institutions on the blacklist are arbitrary and negativeB there is no hard evidence to prove that faster completion rates result from greater efficiency rather than lower standards or less ambitious doctoral topicsC many of the best students go quickly into jobs where they can apply their research skills, but consequently take longer to finish their diesesD some polytechnics are penalized by random fluctuations in student performance29.The ESRC would prefer______.A that me students were carrying out purely knowledge-based studies rather than being trained as researchersB to see higher standards of PhD students' theses and more ambitious doctoral topicsC more systematic teaching of research skills to fewer unrealistic expectations placed on inexperienced young PhD studentsD that PhD students were less modest in their aims30.What the ESRC can do is to______.A force departments to give graduates more teaching timeB try to persuade universities to change their waysC dictate me standard of diesis required by external examinersD note mat students want more research training and less elaborate style of thesis2. English-Chinese Translation1.Washington Irving grasped this fact nearly a hundred years ago when he wrote: "The stranger who would form a correct opinion of English character must go forth into the country. He must sojourn in villages and hamlets; he must visit castles, villas, farmhouses, cottages; he must wander through parks and gardens, along hedges and green lanes; he must loiterabout country churches, attend wakes and fairs and other rural festivals, and cope with me people in all their conditions and all their habits and humors. "2.The impact of decentralization trends, of course, extends well beyond cities. Sprawling development patterns are destabilizing many of the suburbs that surround America's cities. Older suburbs are experiencing the same challenges as cities: failing schools, persistent crime, and the loss of jobs and businesses to other, further out suburbs. Even suburban areas that are developing rapidly are finding that explosive growth has its drawbacks, especially in the form of overcrowded schools, but also in long commutes and the inability of local governments to pay for new roads, sewers, and other infrastructure.3.
