30、【 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 (l)Although numbers of an
31、imals 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 population to peri
32、odic 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 of sunlight), for e
33、xample, can govern population growth. This theory the density-independent view asserts 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-dependent that is, th
34、e 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 shown, predato
35、rs 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 adrenal glands (肾上腺
36、 ) 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 that would allow
37、 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 codes provide or
38、ganisms 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 the following m
39、ay 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 aggregations （ B） lo
40、cating 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 (l)Science is com
41、mitted 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 twentieth century t
42、here 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 universalizing tendency
43、. This is why the spread of technology makes the world look ever more homogeneous. Architectural styles, dress styles, musical styles even eating styles tend increasingly to be world styles. The world looks more homogeneous because it is more homogeneous. Children who grow up in this world therefore
44、 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 described precis
45、ely 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 economics of automob
46、iles, 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 who makes the
47、m. (4)As in architecture, so in automating. 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 tell one make fr
48、om another. In other words, the specifically American traits that lingered in American automobiles in the 1960s traits that linked American cars to American history are disappearing. Even the Volkswagen Beetle has disappeared and has taken with it the visible evidence of the history of streamlining 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, modem man is becoming universal. No longer quite an i
