【正文】 arching and its attitude of general expectancy instead of anticipating are silkthin veils of tranquility over an explosive endocrine system. 51. The author is primarily concerned with A. disproving the view that herbivores are less intelligent than carnivores. B describing a relationship between animals, intelligence and their ecological roles. C establishing a direct link between early large mammals and their modern counterparts. D. analyzing the ecological basis for the dominance of some carnivores over other carni vores. E. demonstrating the importance of hormones in mental activity. 52. The author refers to a hungry lizard primarily in order to A. demonstrate the similarity between the hunting methods of mammals and those of nonmammals. B. broaden the application of his argument by including an insectivore as an example. C. make a distinction between higher and lower levels of consciousness. D. provide an additional illustration of the brutality characteristic of predators. E. offer an objection to suggestions that all animals lack consciousness. 53. It can be inferred from the passage that in animals less intelligent than the mammals dis cussed in the passage A. past experience is less helpful in ensuring survival. B. attention is more highly focused. C. muscular coordination is less highly developed. D. there is less need for petition among species. E. environment is more important in establishing the proper ratio of prey to predator. 54. The sensitivity described in lines 35 57 is most clearly an example of A. freefloating awareness. （ lines 10） B. flooding of impulses in the brain stem. （ line 18） C. the holding of consistent images. （ lines 19 20） D. integration of details with perceived ends and purposes. （ lines 22 23） E. silkthin veils of tranquility. （ lines 39 40） 55. The author39。s attitude toward the mammals discussed in the passage is best described as A. superior and condescending. B. lighthearted and jocular. C. apologetic and conciliatory. D. wistful and tender. E. respectful and admiring. 56. The author provides information that would answer which of the following questions? I .Why is an aroused herbivore usually fearful? II. What are some of the degrees of attention in large mammals? III. What occurs when the stimulus that causes arousal of a mammal is removed? A. I only. B. III only. C. I and II only. D. H and III only. E. I , II ,and III. 57. According to the passage, improvement in brain function among early large mammals re suited primarily from which of the following? A. Interplay of predator and prey. B. Persistence of freefloating awareness in animals of the grasslands. C .Gradual dominance of warmblooded mammals over coldblooded reptiles D. Interaction of early large mammais with less intelligent species. E. Improvement of the capacity for memory among herbivores and carnivores. 58. According to the passage, as the process of arousal in an anism continues, all of the following may occur EXCEPT A. the production of adrenaline. B. the production of norepinephrine. C. a heightening of sensitivity to stimuli. D. an increase in selectivity with respect to stimuli. E. an expansion of the range of states mediated by the brain stem. D Upwards of a billion stars in our galaxy have burnt up their internal energy sources, and so can no longer produce the heat a star needs to oppose the inward force of gravity. These stars, of more than a few solar masses, evolve, in general, much more rapidly than does a star like the Sun. Moreover, it is just these more massive stars whose collapse does not halt it intermediate stages （ that is, as white dwarfs or neutron stars） . Instead, the collapse con tinues until a singularity （ an infinitely dense concentration of matter） is reached. It would be wonderful to observe a singularity and obtain direct evidence of the undoubt edly bizarre phenomena that occur near one. Unfortunately in most cases a distant observer cannot see the singularity。 outgoing light rays are dragged hack by gravity so forcefully that even if they could start out within a few kilometers of the singularity, they would end up in the singularity itself. 59. The author39。s primary purpose in the passage is to A. describe the formation and nature of singularities. B. explain why large numbers of stars bee singularities. C. pare the characteristics of singularities with those of stars. D. explain what happens during the stages of a singularity39。s formation. E. imply that singularities could be more easily studied if observers could get closer to them. 60. Which of the following sentences would most probably follow the last sentence of the passage? A. Thus, a physicist interested in studying phenomena near singularities would necessa rily hope to find a singularity with a measurable gravitational field. B. Accordingly, physicists to date have been unable to observe directly any singularity. C. It is specifically this startling phenomenon that has allowed us to codify the scant in formation currently available about singularities. D. Moreover, the existence of this extraordinary phenomenon is implied in the extensive reports of several physicists. E. Although unanticipated, phenomena such as these are consistent with the structure of a singularity. Ⅲ . Identify and underline the rhetorical devices used in each sentence. （ 14%） 1.
