To determine the consequences of sleep deficit, researchers have put subjects through a set of psychological and performance tests requiring them, for instance, to add columns of numbers or recall a passage read to them only minutes earlier. "We’ve found that if you’re in sleep deficit, performance suffers, " says Dr. David. "Short-term memory is weakened, as are abilities to make decisions and to concentrate."
　　37. To "live a completely sedentary life-style" (Line 7, Para. 1) in the passage means _____.
　　(A) to "live a decent life"
　　(B) to "live an inactive life"
　　(C) to "live a life of vice"
　　(D) to "live a life with complete freedom"
　　The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illness may be preventable if individuals would make sound personal health choices based upon current medical knowledge. We all enjoy our freedom of choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever food we want, and live a completely sedentary life-style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.
　　24. The word "dormant" (Para. 4, Line 3) most probably means _____.
　　(A) inactive
　　(B) strong
　　(C) alert
　　(D) soft
　　If sufficient rain falls the next year to form another lake, the eggs hatch, and once again the shrimps pass rapidly through their cycle of growth, adulthood, egg-laying, and death. Some years there is insufficient rain to form a lake: in this case, the eggs will remain dormant for another years, or even longer if necessary. Very, very occasionally, perhaps twice in a hundred years, sufficient rain falls to form a deep lake that lasts a month or more. In this case, the species passes through two cycles of growth, egg-laying, and death. Thus, on such occasions, the species multiplies considerably, which further ensures its survival.
　　33. From the context, the word "disconcerting" (Para. 3, Line 2) most probably means _____.
　　(A) misleading
　　(B) embarrassing
　　(C) stimulating a goal wit
　　(D) upsetting
　　注：焦虑anxiety
　　To some, the thought of having to write an assigned number of pages, often more than ever produced before, is disconcerting. To others, the very idea of having to work independently is threatening. But there is no need to approach the research paper assignment with anxiety, and nobody should view the research paper as an
　　obstacle to overcome. Instead, consider it a goal to accomplish, a goal within reach if you use the help this book can give you.
　　21. The word "pinpoint" (para. 1,) basically means _______.
　　A) appreciate
　　B) obtain
　　C) interpret
　　D) identify
　　 The process of perceiving other people is rarely translated (to ourselves or other’s) into cold, objective terms. "She was 5 feet 8 inches tall, had had fair hair, and wore a colored skirt." More often, we try to get inside the other person to pinpoint his or her attitudes, emotions, motivations, abilities, ideas and characters. Furthermore, we sometimes behave as if we can accomplish this difficult job very quickly -perhaps with a two-second glance.
　　31. The word "paradox" (Para. 1,) means "_________" .
　　A) implication
　　B) contradiction
　　C) interpretation
　　D) confusion
　　 It is a curious paradox that we think of the physical sciences as "hard", the social sciences as "soft", and the biological sciences as somewhere in between, This is interpreted to mean that our knowledge of physical systems is more certain than our knowledge of biological systems, and these in turn are more certain than our knowledge of social system. In terms of our capacity to sample the relevant universes, however, and the probability that our images of these universes are at least approximately correct, one suspects that a reverse order is more reasonable. We are able to sample earth’ s social systems with some degree of confidence that we have a reasonable sample of the total universe being investigated. Our knowledge of mal systems, therefore, while it is in many ways extremely inaccurate, is not likely to be seriously overturned by new discoveries. Even the folk knowledge in social systems on which ordinary life is based in earning, spending, organizing, marrying, taking part in political activities, fighting and so on, is not very dissimilar from the more sophisticated images of the social system derived from the social sciences, even though it is built upon the very imperfect samples of personal experience.
　　26. The word "liability" (Para. 1) most probably means "______".
　　A) misfortune
　　B) instability
　　C) disadvantage
　　D) burden
　　Beauty has always been regarded as something praiseworthy. Almost everyone thinks attractive people are happier and healthier, have better marriages and have more respectable occupations. Personal consultants give them better advice for finding jobs. Even judges are softer on attractive defendants. But in the executive circle, beauty can become a liability.
　　28. The phrase "function in the disservice of one another" (Para. 1) most probably means "_______".
　　A) betray each other
　　B) harm one another
