1、2014年北京师范大学考博英语真题试卷及答案解析(总分：66.00，做题时间：90 分钟)一、Reading Comprehensio(总题数：6，分数：60.00)Taken together, income, occupation, and education are good measures of peoples social standing. Using a layered model of stratification, most sociologists describe the class system in the United States as divided into
2、 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
3、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 t
4、he 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 me contrary, the best predictor of future wealth is the family into which you are born. Each year, the
5、 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 origi
6、ns; 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 accepted into “old rich“ circles. The upper middle class includes those w
7、ith high incomes and high social prestige. They tend to be well-educated professionals or business executives. Their earnings can be quite high indeedsuccessful business executives can earn millions of dollars a year. It is difficult to estimate exactly how many people fall into this group because o
8、f 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 Unite
9、d 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 disposal. But the idea that the United States is a
10、n 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 tenuo
11、us 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 lab
12、or)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 pos
13、ition 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 in
14、 minimum-wage jobs. Forty percent of the poor work; 10 percent work year-round and full timea 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
15、 developments. Rejected from the economic system, those in the underclass may become dependent on public assistance or illegal activities.（分数：10.00）(1).Why does the author mention the “Forbes 400“ in Paragraph 3?（分数：2.00）A.To explain the meaning of the listing that appears every year.B.To cast doubt

21、c system.“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,
22、 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, werent acting out of unselfishness. They knew their economics were the most compet
23、itive, so theyd profit most from liberalization. And developing countries feared that their economics would be swamped by superior Western productivity. Today, however, the tables have turnedthough few acknowledge it. The west continues to preach free trade, but practices it less and less. Asia, mea
24、nwhile, continues to plead for special protection but practices more and more free trade. Thats why Sarkozys word was so important: he finally injected 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 econ
25、omists are more honest. Paul Krugman is one of the few willing to acknowledge that protectionist arguments are returning. In the short run, there will be winners and losers will be in the West. Economists in the developed world used to love quoting Joseph Schumpeter, who said that “creative destruct
26、ion“ 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 theres clearly a negative trend in Wes
27、tern 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 global economic and financial institutions while drifting away from global liberalization. Look at whats happening at t
28、he 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 elses when they dominate these global institutions. The time has therefore come for the Asianswho are clearly the
29、 new winners in todays global economyto provide more intellectual leadership in supporting free trade. Sadly, they have yet to do so. Unless Asians speak out, however, theres a real danger that Adam Smiths principles, which have brought so much good to the world, could gradually die. And that would
30、leave all of us worse off, in one way or another.（分数：10.00）(1).It can be inferred that “protection“(Line 1, Para. 1)means_.（分数：2.00）A.improving economic efficiencyB.ending the free-trade practiceC.lowering moral standardD.raising trade tariffs(2).The Western leaders preach free trade because_.（分数：2.

34、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 leadersGrowth, reproduction, and daily metabolism all require an organism to expend energ
35、y. The expenditure of energy is essentially a process of budgeting, just as finances are budgeted. If all of ones money is spent on clothes, mere 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
36、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 organi
37、sm 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 organisms energy can be diverted to reproduct
38、ion, with very little allocated to building the body. Organisms 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
39、. 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. The
40、se 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 not build big bodies, they cannot compete with other plants fo
41、r 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. Oppo
42、rtunists 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
43、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 uns
44、tablesoaring 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 2
45、00 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 o
46、f the defense mechanism that is essential to longevity. Although oaks produce thousands of acoms, 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
47、 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 opportun
48、ist or pure competitor is rare in nature, as most species fall between the extremes of a continuum, exhibiting a blend of some opportunistic and some competitive characteristics.（分数：10.00）(1).The word “squander“ in the passage is closest in meaning to_.（分数：2.00）A.extendB.transformC.activateD.waste(2
49、).According to the passage, the classification of organisms as “opportunists“ or “competitors“ is determined by_.（分数：2.00）A.how the genetic information of an organism is stored and maintainedB.the way in which the organism invests its energy resourcesC.whether the climate in which the organism lives is mild or extremeD.the variety of natural resources the organism consumes in its environment(3).All of the following are mentioned in Paragraph 7 as contribution to the longevity of oak trees EXCEPT_.（分数：2.00）A.the capacity to
