　　Part II Reading Comprehension (35 minutes)
　　Directions: There are 4 reading passages in this part. 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 mark the corresponding letter on the Answer Sheet with a single line through the center.
　　Questions 21 to 25 are based on the following passage:
　　How often do you sit still and do absolutely nothing? The usual answer these days is never, or hardly ever. As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down and unwind. But relaxation is essential for a healthy mind and body.
　　Stress is a natural part of everyday life. There is no way to avoid it, since it takes many and varied forms—driving in traffic, problems with personal relationships are all different forms of stress. Stress, in fact, is not as bad as it is often reputed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to level performance and ill health.
　　The amount of stress a person can withstand depends very much on the individual. Some people thrive on stress, and such characters are obviously prime material for managerial responsibilities. Others crumple at the sight of unusual difficulties.
　　When exposed to stress, in whatever form, we react both chemically and physically. In fact we invoke the fight mechanism which in more primitive days made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however minimal the stress, it involves the same response. All the energy is diverted to cope with the stress, with the result that other function, such as digestion, are neglected.

　　It is when such a reaction is prolonged, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure, coronary heart disease all have established links with stress. The way stress affects a person also varies with the individual. Stress in some people produces stomach disorders, while others succumb to tension headaches. Since we cannot remove stress from our lives, we need to find ways to cope with it.

　　Questions 26 to 30 are based on the following passage:
　　Industry uses water for many different purposes. The uses are commonly divided into four categories: cooling water, process water, boiler feedwater, and sanitary and service water. Cooling water is water used only for cooling without coming into contact with the product of material being processed. Process water is water that comes into contact with material being processed. Boiler feedwater is water converted to steam. Sanitary and service water is that supplied for the personal use of the employees, for cleaning plants and equipment, and for the operation of valves and other apparatus.

　　About 90 percent of the water withdrawn by industry is used for cooling. Fuelelectric power plants use more cooling water than all other kinds of plants combined. One might suppose that the greatest amount of water used in the fuelelectric power production is used for boiler feedwater, but such use is dwarfed by the water needed for cooling condensers. Cooling water is also used to condense many products of oil refineries and chemical plants and to protect industrial equipment from excessive heat.
　　Most manufacturing plants use process water at some point in the course of their operation. In some plants the material being processed is in contact with water at almost every step in its conversion to the finished product. Water also serves as a solvent for chemicals in many chemical processes; and the food industry uses large quantities of water for cleaning, cooking, and canning vegetables and meats.
　　Another important use of water by industry is for disposal of its waste products. At one time, streamflows were adequate to dilute, dissolve, or carry away these wastes. However, some rivers in the United States are being progressively depleted by use and overloaded with wastes. This pollution not only upsets the delicate natural balance among plants, insects, and fish, but also poses problems of water quality for the people and industries downstream.
　　26．What does the passage mainly discuss?
　　A. Why does industry use the most water for cooling.
　　B. The conversion of raw material into finished products.
　　C. The disposal of waste products in industry.
　　D. Four basic categories of water used in industrial production.
　　27．Water used in industry to operate valves is called .
　　A. sanitation and service waterB. boiler feedwater
　　C. cooling waterD. process water
　　28．Which of the following is NOT mentioned as one of the functions of water used in industrial production?
　　A. coolingB. solvent for chemicals
　　C. carrier of waste productsD. cleaning
　　29．The greatest amount of cooling water is used in .
　　A. food industryB. fuelelectric power plant
　　C. chemical industryD. manufacturing industry
　　30. The word “depleted in the last paragraph most probably means .
　　A. used upB. pollutedC. flushedD. flooded

　　Questions 31 to 35 are based on the following passage:
　　Some gaybashers believe AIDS (艾滋病) is Gods way of punishing homosexuals (同性恋). Some Africans suspect it is just another of the white mans weapons of genocide (种族灭绝). Others suggested it was hatched in a biologicalweapons laboratory. There has been no shortage of theories about the origins of the virus that caused the current worldwide AIDS epidemic (传染病), but most have ranged from truly bizarre to scientifically implausible at best.
　　African monkeys are almost certainly the source of the deadly virus. Just how the virus made the leap from its simian (猿猴的) host to people is still hotly debated, however, and the most likely explanations are far more complex, involving shifts in African society that turned an isolated disease into a plague.
　　Though researchers initially resisted the idea that human AIDS also came from African monkeys, that fact now seems well established. In 1991, convincing evidence was presented that the simian virus that infects sooty mangabbys, a type of monkey found in West Africa, carries virtually the same genetic material as HIV2, one of the two strains of human AIDS virus.
　　One theory of how the virus traveled from monkeys to humans is based on reports that certain West Tribes injected monkey blood into their backs and thighs to heighten sexual arousal. Other researchers have referred to bizarre attempts by European doctors in the 1920s to boost the flagging (衰退的) powers of aging men with injections of monkey testicles(睾丸).
　　The most compelling explanation for the spread of the AIDS virus is cultural as well as biological. The actual transfer of the virus from monkeys to humans may have involved something as prosaic (平凡的) as a monkey bite or a monkey hunters nick on the hand while butchering his quarry (猎物). Some experts believe that AIDS might have died out with that hunter, or perhaps with his isolated village, had profound cultural changes not come to Africa. Over the last 30 years, the population of subSaharan Africa, the region hardest hit by AIDS, became increasingly urban. As in the United States, infection rates appear far higher in African cities than in rural areas. Urbanization brings many diverse people together. It appears that the AIDS virus is approximately 40 years old. That places its origin right at the beginning of the period of rapid African urban development. As with the history of plagues, tracing the precise movements of the AIDS virus through various populations is exceedingly difficult. In the end, the origin of AIDS is not the real problem; the real problem is where the disease is going.

　　Questions 36 to 40 are based on the following passage:
　　We have seen that all living things must take in and use energy to maintain their bodies, to grow, to obtain more energy, and to reproduce. Since the evolutionarily successful individual is one that leaves descendants in future generations, natural selection favors those individuals that can channel the most energy into producing offspring. The use of energy in other activities such as feeding, fighting, or growing is selectively advantageous only so far as these activities result in the organisms accumulating more energy to produce offspring.
　　Each individual has an energy income—all of the energy that it acquires during its lifetime. It also has an energy budget, its allotment of different amounts of energy to various activities. The most evolutionarily successful organisms are those which are most effective in conversion of energy to offspring. This does not mean that organisms use all their energy directly to produce offspring. For example, suppose that a tree converts some of its energy into growing a large root system, the energy thus spent cannot be used to produce offspring. Its large root system may enable the tree to obtain a great deal of water and minerals from the soil and so to produce more leaves, another diversion of energy away from the production of offspring. However, all of the leaves that the tree produces may then enable the tree to synthesize more food than it would have otherwise, and so allow it to make up for some of its previous energy expenditure by producing more offspring in the end. Thus organisms make energy investment which may ultimately yield energy gains that can be reinvested in the production of offspring. Sometimes these investments will turn out to be selectively disadvantageous because they postpone production of offspring. If the organism meets an early death, it will never get a chance to reproduce. So any item in an organisms energy budget must have the potential to produce an ultimate productive gain that is equal to the risks involved in diverting energy away from the immediate production of offspring.
　　36. What is the main idea of the passage?
　　A. Each individual has an energy income and an energy budget as well.
　　B. Sometimes the investment of energy can be disadvantageous to organisms.
　　C. The most evolutionarily successful individual is one that directs the most energy to reproduction.
　　D. Any item in an organisms energy budget must have the potential of reproduction that is equal to the risks involved in diverting energy away from the reproductive process.
　　37. What does the word “allotment” in the second paragraph most probably mean?
　　A. reservationB. divisionC. productionD. accumulation
　　38. According to the passage, the use of energy in feeding, fighting or growing would be selectively disadvantageous when .
　　A. these activities dont lead to the accumulation of more energy of the organism to produce offspring
