25、ed such proportions that local governments cant possibly 【 C1】 _. To help homeless people toward independence, the federal government must support job training programs, raise the minimum wage, and fund more low-cost housing. Not everyone agrees on the number of Americans who are homeless. Estimates

One of the federal governments studies predicts that the number of the homeless will reach nearly 19 million by the end of this decade. Finding wa

27、ys to 【 C3】 _ this growing homeless population has become increasingly difficult. Even when homeless individuals manage to find a 【 C4】 _ that will give them three meals a day and a place to sleep at night, a good number still spend the bulk of each day 【 C5】 _ the street. Part of the problem is tha

28、t many homeless adults are addicted to alcohol or drugs. And a significant number of the homeless have serious mental disorders. Many others while not addicted or 【 C6】_ ill, simply lack the everyday 【 C7】 _ skills needed to turn their lives around. Boston Globe reporter Chris Reidy notes that the s

30、【 C3】 45 【 C4】 46 【 C5】 47 【 C6】 48 【 C7】 49 【 C8】 50 【 C9】 51 【 C10】 SECTION A In this section there are several passages followed by ten multiple-choice questions. For each question, there are four suggested answers marked A, B, C and D. Choose the one that you think is the best answer. 51 (1)Alth

31、ough numbers of animals in a given region may fluctuate from year to year, the fluctuations are often temporary and, over long periods, trivial. Scientists have advanced three theories of population control to account for this relative constancy. (2)The first theory attributes a relatively constant

32、population to periodic climatic catastrophes that decimate populations with such frequency as to prevent them from exceeding some particular limit. In the case of small organisms with short life cycles, climatic changes need not be catastrophic: normal seasonal changes in photoperiod (daily amount o

33、f sunlight), for example, can govern population growth. This theorythe density-independent viewasserts that climatic factors exert the same regulatory effect on population regardless of the number of individuals in a region. (3)A second theory argues that population growth is primarily density-depen

34、dentthat is, the rate of growth of a population in a region decreases as the number of animals increases. The mechanisms that manage regulation may vary. For example, as numbers increase, the food supply would probably diminish, which would increase mortality. In addition, as Lotka and Volterra have

35、 shown, predators can find prey more easily in high-density populations. Other regulators include physiological control mechanisms: for example, Christian and Davis have demonstrated how the crowding that results from a rise in numbers may bring about hormonal changes in the pituitary (垂体 ) and adre

36、nal glands (肾上腺 ) that in turn may regulate population by lowering sexual activity and inhibiting sexual maturation. There is evidence that these effects may persist for three generations in the absence of the original provocation. One challenge for density-dependent theorists is to develop models t

37、hat would allow the precise prediction of the effects of crowding. (4)A third theory, proposed by Wynne-Edwards and termed “epideictic“, argues that organisms have evolved a “code“ in the form of social or epideictic behavior displays, such as winter roosting aggregations or group vocalizing; such c

38、odes provide organisms with information on population size in a region so that they can, if necessary, exercise reproductive restraint However, Wynne-Edwards theory, linking animal social behavior and population control, has been challenged, with some justification, by several studies. 52 Which of t

39、he following may be a density-independent factor that affects animal population? （ A） Famine. （ B） Tornadoes. （ C） The number of predators. （ D） The variety of food supply. 53 According to the Wynne-Edwards theory, epideictic behavior displays serve the function of _. （ A） determining roosting aggre

40、gations （ B） locating food （ C） attracting predators （ D） regulating sexual activity 54 The challenge posed to the Wynne-Edwards theory by several studies is regarded by the author with _. （ A） complete indifference （ B） qualified acceptance （ C） skeptical amusement （ D） perplexed astonishment 54 (1

41、)Science is committed to the universal. A sign of this is that the more successful a science becomes, the broader the agreement about its basic concepts. There is not a separate Chinese or American or Soviet thermodynamics, for example; there is simply thermodynamics. For several decades of the twen

42、tieth century there was a Western and a Soviet genetics, the latter associated with Lysenkos theory that environmental stress can produce genetic mutations. Today Lysenkos theory is discredited, and there is now only one genetics. (2)As the corollary of science, technology also exhibits the universa

43、lizing tendency. This is why the spread of technology makes the world look ever more homogeneous. Architectural styles, dress styles, musical styleseven eating stylestend increasingly to be world styles. The world looks more homogeneous because it is more homogeneous. Children who grow up in this wo

44、rld therefore experience it as a sameness rather than a diversity, and because their identities are shaped by this sameness, their sense of differences among cultures and individuals diminishes. As buildings become more alike, the people who inhabit the buildings become more alike. The result is des

45、cribed precisely in a phrase that is already familiar: the disappearance of history. (3)The automobile illustrates the point with great clarity. A technological innovation like streamlining or all-welded body construction may be rejected initially, but if it is important to the efficiency or economi

46、cs of automobiles, it will reappear in different ways until it is not only accepted but universally regarded as an asset. Todays automobile is no longer unique to a given company or even to a given national culture, its basic features are found, with variations, in automobiles in general, no matter

47、who makes them. (4)As in architecture, so in automaking. In a given cost range, the same technology tends to produce the same solutions. The visual evidence for this is as obvious for cars as for buildings. Today, if you choose models in the same price range, you will be hard put at 500 paces to tel

48、l one make from another. In other words, the specifically American traits that lingered in American automobiles in the 1960straits that linked American cars to American historyare disappearing. Even the Volkswagen Beetle has disappeared and has taken with it the visible evidence of the history of st

49、reamlining that extends from DArcy Thompson to Carl Breer to Ferdinand Porsche. (5)If man creates machines, machines in turn shape their creators. As the automobile is universalized, it universalizes those who use it. Like the World Car he drives, modern man is becoming universal. No longer quite an individual,
