中国科学技术大学20XX年博士研究生入学考试英语试题附答案和详解SECTION Ⅰ LISTENING COMPREHENSION (20 points)(略)SECTION Ⅱ READING COMPREHENSION (30 points)Directions: There are 5 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 then blacken the corresponding letter on the ANSWER SHEET.Passage OneQuestions 21 to 24 are based on the following passage.When, in the age of automation, man searches for a worker to do the tedious, unpleasant jobs that are impossible to mechanize, he may very profitably consider the ape.If we tackled the problem of breeding for brains with as much as enthusiasm as we devote to breeding dogs of surrealistic shapes, we could eventually produce assorted models of useful primates,ranging in size from the gorilla down to the baboon, each adapted to a specific kind of work. It is not putting too much strain on the imagination to assume that geneticists could produce a super-ape, able to understand some scores of words, and capable of being trained for such jobs as picking fruit, cleaning up the litter in parks, shining shoes, collecting garbage, doing household chores, and even baby-sitting (though I have known some babies I would not care to trust with a valuable ape).Apes could do many jobs, such as cleaning streets and the more repetitive types of agricultural work, without supervision, though they might need protection from those exceptional specimens of Homo sapiens who think it amusing to tease or bully anything they consider lower on the evolutionary ladder. For other tasks, such as delivering papers and laboring on the docks, our man-ape would have to work under human overseers; and, incidentally, I would love to see the finale of the twenty-first century version of on the Waterfront in which the honest but hairy hero will drum on his chest after-literally taking the wicked labor leader apart.Once a supply of nonhuman workers becomes available, a whole range of low IQ jobs could be thankfully relinquished by mankind, to its great mental and physical advantage. What is more, one of the problems which have plagued so many fictional Utopias would be avoided: Therewould be none of the degradingly subhuman Epsilons of Huxley's Brave New World to act as a permanent reproach to society, for there is a profound moral difference between breeding sub-men and super-apes, though the end products are much the same. The first would introduce a form of slavery;the second would be a biological triumph which could benefit both men and animals.21．In the author's opinion, the idea that geneticists could produce a super-ape is ______.A．irrational B．plausibleC．biologically impossible D．demonstrably true22．The type of job an ape could do without supervision would be one which is ______.A．repetitive B．mechanized C．unusual D．intricate23．A problem that has plagued some fictional Utopias is ______.A．creation of super-apes B．the necessity of breeding super-humans C．the necessity of breeding subhumans D．the degradation of beasts24．The author of this article isA．revealing his low opinion of mankindB．poking fun at geneticistsC．expressing his doubts about the possibility of breeding a super-apeD．presenting a reasonable theory in a humorous tonePassage TwoQuestions 25 to 28 are based on the following passage.As one works with color in a practical or experimental way, one is impressed by two apparently unrelated facts. Color as seen is a mobile changeable thing depending to a large extent on the relationship of the color to other colors seen simultaneously. It is not fixed in its relation to the direct stimulus which creates it. On the other hand, the properties of surfaces that give rise to color do not seem to change greatly under a wide variety of illumination colors, usually (but not always) looking much the same in artificial light as in daylight. Both of these effects seem to be due in large part to the mechanism of color adaptation mentioned earlier.When the eye is fixed on a colored area, there is an immediate readjustment of the sensitivity of the eye to color in and around the area viewed. This readjustment does not immediately affect the color seen but usually does affect the next area to which the gaze is shifted. The longer the time of viewing, the higher the intensity, and the larger the area, the greater the effect will be interms of its persistence in the succeeding viewing situation. As indicated by the work of Wright and Shouted, it appears that, at least for a first approximation, full adaptation takes place over a very brief time if the adapting source is moderately bright and the eye has been in relative darkness just previously.As the stimulus is allowed to act, however, the effect becomes more persistent in the sense that it takes the eye longer to regain its sensitivity to lower intensities. The net result is that, if the eye is so exposed and then the gaze is transferred to an area of lower intensity, the loss of sensitivity produced by the first area will still be present and appear as an “afterimage” superimposed on the second.The effect not only is present over the actual area causing the “local adaptation” but also spreads with d ecreasing strength to adjoining areas of the eye to produce “lateral adaptation”. Also, because of the persistence of the effect of the eye is shifted around from one object to another, all of which are at similar brightness or have similar colors,the adaptation will tend to become uniform over the whole eye.25．This selection is primarily concerned with ______.A．the eye's adaptation to color B．the properties of colored surfacesC．the color of colors D．the effect of changes in color intensity 26．Whether a colored object would, on two viewings separated in time, appear to the viewer as similar or different in color would depend mostly on ______.A．the color mechanism of the eye in use at the time of each viewingB．whether the object was seen in artificial or natural lightC．what kind of viewing had immediately preceded each of the viewingsD．the individual's power of lateral adaptation27．If a person's eye has been looking at an object in bright sunlight for some time, and then shifts to an object not well lit, we can expect ______.A．a time lag in the focusing ability of the eyeB．some inability to see colors of the latter-named objects until loss of sensitivity has been regainedC．the immediate loss of the “afterimage” of the fir st objectD．the adaptation in the central area of the eye but little adaptation in the lateral areas to the new intensity level28．The present selection has apparently been preceded by some explanation of ______.A．some experiments with color pigmentsB．the nature of colorC．the color properties of various surfacesD．the mechanism of the eye's adaptation to colorPassage ThreeQuestions 29 to 32 are based on the following passage.The Greek's lofty attitude toward scientific research—and the scientists' contempt of utility —was a long time dying. For a millennium after Archimedes, this separation of mechanics from geometry inhibited fundamental technological progress and in some areas repressed it altogether.But there was a still greater obstacle to change until the very end of the middle ages: the organization of society. The social system of fixed class relationships that prevailed through the Middle Ages (and in some areas much longer) itself hampered improvement.Under this system, the laboring masses, in exchange for the bare necessities of life, did all the productive work, while the privileged few—priests, nobles, and kings—concerned themselves only with ownership and maintenance of their own position.In the interest of their privileges they did achieve considerable progress in defense, in war making, in government, in trade, in the arts of leisure, and in the extraction of labor from their dependents, but they had no familiarity with the process of production.On the other hand, the laborers, who were familiar with manufacturing techniques, had no incentive to improve or increase production to the advantage of their masters. Thus, with one class possessing the requisite knowledge and experience, but lacking incentive and leisure, and the other class lacking the knowledge and experience, there was no means by which technical progress could be achieved.The whole ancient word was built upon this relationship— a relationship as sterile as it was inhuman. The availability of slaves nullified the need for more efficient machinery. In many of the commonplace fields of human endeavor, actual stagnation prevailed for thousands of years. Not all the glory that was Greece and the grandeur that was Rome could develop the windmill or contrive so simple an instrument as the wheelbarrow—products of the tenth and thirteenth centuries respectively.For about twenty-five centuries, two-thirds of the power of the horse was lost because he wasn't shod, and much of the strength of the ox was wasted because his harness wasn't modified tofit his shoulders. For more than rive thousand years, sailors were confined to rivers and coasts by a primitive steering mechanism which required remarkably little alteration (in the thirteenth century)to become a rudder.With any ingenuity at all, the ancient plough could have been put on wheels and the ploughshare shaped to bite and turn the sod instead of merely scratching it—but the ingenuity wasn't forthcoming. And the villager of the Middle Ages, like the men who first had fire, had a smoke hole in the center of the straw and reed thatched roof of his' one-room dwelling (which he shared with his animals), while the medieval charcoal burner (like his Stone Age ancestor) made himself a hut of small branches.29．Lack of technological progress in the ancient and medieval worlds was primarily due to the absence of ______.A．natural resourcesB．inventive abilityC．people's desire for the “better things of life”D．proper social organization30．During the Middle Ages, productivity of labor ______.A．was a primary concern of societyB．was hampered by class relationshipsC．began to improve over levels reached by the GreeksD．was in a period of technical progress31．We may infer that a change in class relationships after the close of the Middle Ages produced greater productivity because ______.A．freemen had incentive to produce moreB．masters had greater incentive to work their workers harderC．slaves never starved, no matter what they producedD．productivity could go in only one direction32．In supporting his contentions about the ancient world, the author relies mainly on illustrations drawn from ______.A．examples of the separation of mechanics and geometryB．case studies of lack of social communication between classesC．technologyD．his concern with the plight of the laboring classesPassage FourQuestions 33 to 36 are based on the following passage.The evolution of sex ratios has produced, in most plants and animals with separate sexes,approximately equal numbers of males and females.Why should this be so? Two main kinds of answers have been offered. One is couched in terms of advantage to population. It is argued that the sex ratio will evolve so as to maximize the number of meetings between individuals of the opposite sex. This is essentially a “group selection” argument. The other, and in my view correct, type of answer was first put forward by Fisher in 1930．This “genetic” argument starts from the assumption that genes can influence the relative numbers of male and female offspring produced by an individual carrying the genes.That sex ratio will be favored which maximizes the number of descendants an individual will have and hence the number of gene copies transmitted.Suppose that the population consisted mostly of females, then an individual who produced sons only would have more grandchildren. In contrast, if the population consisted mostly of males, it would pay to have daughters. If, however, the population consisted of equal numbers of males and females, sons and daughters would be equally valuable. Thus a one-to-one sex ratio is the only stable ratio; it is an “evolutionarily stable strategy”.Although Fisher wrote before the mathematical theory of games had been developed,his theory incorporates the essential feature of a game that the best strategy to adopt depends on what others are doing.Since Fisher's time, it has been realized that genes can sometimes influence the chromosome or gamete in which they find themselves so that the gamete will be more likely to participate in fertilization.If such a gene occurs on a sex-determining (X or Y) chromo-some,then highly aberrant sex ratios can occur. But more immediately relevant to game theory are the sex ratios in certain parasitic wasp species that have a large excess of females. In these species, fertilized eggs develop into females and unfertilized eggs into males. A female stores sperm and can determine the sex of each egg she lays by fertilizing it or leaving it unfertilized.By Fisher's argument, it should still pay a female to pro duce equal numbers of sons and daughters.Hamilton, noting that the eggs develop within their host—the larva of another insect—and that the newly emerged adult wasps mate immediately and disperse, offered a remarkably cogent analysis. Since only onefemale usually eggs in a given larva, it would pay her to produce one male only, because this one could fertilize all his sisters on emergence.Like Fisher, Hamilton looked for an evolutionarily stable strategy, but he went a step further in recognizing that he was looking strategy.33．The author suggests that the work of Fisher and Hamilton was similar in that both scientists ______.A．conducted their research at approximately the same timeB．sought to manipulate the sex ratios of some of the animals they studiedC．sought an explanation of why certain sex ratios exist and remain stableD．studied reproduction in the same animal species34．It can be inferred from the passage that the author considers Fisher's work to be ______.A．definitive and thoroughB．inaccurate but popular, compared with Hamilton's workC．accurate, but trivial compared with Hamilton's workD．admirable, but not as up-to-date as Hamilton's work35．According to the passage, successful game strategy depends on ______.A．the ability to adjust one's behavior in light of the behavior of othersB．the degree of stability one can create in one's immediate environmentC．the accuracy with which one can predict future eventsD．the success one achieves in conserving and storing one's resources36．It can be inferred from the passage that the mathematical theory of games has been ______.A．developed by scientists with an interest in geneticsB．useful in explaining some biological phenomenaC．adopted by Hamilton in his researchD．based on animal studies conducted prior to 1930Passage FiveQuestions 37 to 40 are based on the following passage.Surprisingly enough, modern historians have rarely interested themselves in the history of the American South in the period before the South began to become self-consciously and distinctively “Southern”—the decades after 1815．Consequently, the cultural history of Britain's NorthAmerican empire in the seventeenth and eighteenth centuries has been written almost as if the Southern colonies had never existed. The American culture that emerged during the Colonial and Revolutionary eras has been depicted as having been simply an extension of New England Puritan culture. However, Professor Davis has recently argued that the South stood apart from the rest of American society during this early period, following its own unique pattern of cultural development. The case for Southern distinctiveness rests upon two related premises: first, that the cultural similarities among the five Southern colonies were far more impressive than the differences, and second, that what made those colonies alike also made them different from the other colonies.The first, for which Davis offers an enormous amount of evidence, can be accepted without major reservations; the second is far more problematic.What makes the second premise problematic is the use of the Puritan colonies as a basis for comparison. Quite properly, Davis decries the excessive influence ascribed by historians to the Puritans in the formation of American culture.Yet Davis inadvertently adds weight to such ascriptions by using the Puritans as the standard against which to assess the achievements and contributions of Southern colonials. Throughout, Davis focuses on the important, and undeniable, differences between the Southern and Puritan colonies in motives for and patterns of early settlement, in attitudes toward nature and Native Americans, and in the degree of receptivity to metropolitan cultural influences.However, recent scholarship has strongly suggested that those aspects of early New England culture that seem to have been most distinctly Puritan, such as the strong religious orientation and the communal impulse, were not even typical of New England as a whole, but were largely confined to the two colonies of Massachusetts and Connecticut.Thus, what in contrast to the Puritan colonies appears to Davis to be peculiarly Southern—acquisitiveness, a strong interest in politics and the law, and a tendency to cultivate metropolitan cultural models—was not only more typically English than the cultural patterns exhibited by Puritan Massachusetts and Connecticut, but also almost certainly characteristic of most other early modern British colonies from Barbados north to Rhode Island: and New Hampshire. Within the larger framework of American colonial life, then, not the Southern—but the Puritan colonies appear to have been distinctive, and even they seem to have been: rapidly assimilating to the dominant cultural patterns by the late Colonial period.37．The author is primarily concerned with ______.A．refuting a claim about the influence of Puritan culture on the early American SouthB．refuting a thesis about the distinctiveness of the culture of the early American SouthC．refuting the two premises that underlie Davis' discussion of the culture of the American D．challenging the hypothesis that early American culture was homogeneous in nature38．According to the author, the depiction of American culture during the Colonial and Revolutionary eras as an extension of New England Puritan culture reflects the ______.A．fact that historians have overestimated the importance of the Puritans in the development of American cultureB．fact that early American culture was deeply influenced by the strong religious orient-colonistsC．extent to which Massachusetts and Connecticut served as cultural models for the other American coloniesD．extent to which colonial America resisted assimilating cultural patterns that were typically English39．The passage suggests that by the late Colonial period the tendency to cultivate metropolitan cultural models was a cultural pattern that was ______.A．dying out as Puritan influence began to growB．self-consciously and distinctively SouthernC．more characteristic of the Southern colonies than of EnglandD．spreading to Massachusetts and Connecticut40．Which of the following statements could most logically follow the last sentence of the passage?A．Thus, without the cultural diversity represented by the American South, the culture of colonial America would certainly have been homogeneous in nature.B．Thus, the contribution of Southern colonials to American culture was certainly overshadowed by that of the Puritans.C．Thus, convergence, not divergence, seems to have characterized the cultural development of the American colonies in the eighteenth century.D．Thus, the culture of America during the Colonial period was far more sensitive to outsideinfluence than historians are accustomed to acknowledge.SECTION Ⅲ VOCABULARY (10 points)Directions: In this section, there are twenty sentences with one word or phrase underlined each.Choose one of the four choices marked A, B, C and D that best keeps the meaning of the sentence if it is substituted for the underlined word or phrase.
