| 第1、2、3、4、5题： There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect”— conserving heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water. Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature — a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would mane agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible) Perhaps, if we are lucky enough, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people neglect the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile? 56. As pointed out at the beginning of the passage, people used to think that air pollution _______. A、 cause widespread damage in the countryside B、 affected the entire eastern half of the United States C、 had damaged effect on health D、 existed merely in urban and industries areas 57. As to the greenhouse effect, the author __________. A、 share the same view with the scientist. B、 is uncertain of its occurrence C、 rejects it as being ungrounded D、 thinks that it will destroy the world soon 58. The word “offset” in the second paragraph could be replaced by _________. A、 slip into B、 make up for C、 set up D、 catch up with 59. It can be concluded that ____________. A、 raising the world’s temperature only a few degrees would not do much harm to life on earth. B、 lowering the world’s temperature merely a few degrees would lead major farming areas to disaster. C、 almost no temperature variations have occurred over the past decade. D、 the world’s temperature will remain constant in the years to come. 60. This passage is primarily about __________. A、the greenhouse effect.. B、 the burning of fossil fuels.. C、 the potential effect of air pollution. D、 the likelihood of a new ice age. |

| 第7、8、9、10、11题：After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day. There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other. Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (Although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement. If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion the counting sheep will put you to sleep! 46 A good title for this passage is ____. A. Sleep C. Dreams B. Good Health D. Work and Rest 47. The word drowsy in the last paragraph means ____. A. sick C. asleep B. stand up D. a little sleepy 48. This passage suggests that not getting enough sleep might make you _____. A. dream more often C. nervous B. have poor health D. breathe quickly 49. During REM, ____. A. your eyes move quickly C. you are restless B. you dream D. both A and B 50. The average number of hours of sleep that an adult needs is ______ . A. approximately six hours C. about eight hours B. around ten hours D. not stated here |

| 第13题：Most young people enjoy physical activities, walking, cycling, football, or mountaineering. These who have a passion 26 climbing high and difficult mountains are often 27 with astonishment. Why are men and women 28 to suffer cold and hardship, and to 29 on high mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activities 30 which men give their leisure. There are no man-made rules, as there are for 31 as golf and football. There are, of course, rules of different kinds which it would be dangerous to 32 , but it is this freedom from man-made rules 33 makes mountaineering attractive to many people. Those who climb mountains are free to their own 34 . If we 35 mountaineering with other more familiar sports, we might think that one big difference is 36 mountaineering is not a “team work”. However, it is only our misunderstanding. There are, in fact, no :matches” 37 “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may 38 , obviously, there is teamwork. A mountain climber knows that he may have to fight with natural 39 that ate stronger and more powerful than man. His sport requires high mental and 40 qualities. A mountain climber 41 to improve on skill year after year. A skier is probably past his best by the age of thirty, and most international tennis champions 42 in their early twenties. But it is not 43 for men of fifty or sixty to climb the highest mountains in the Alps. They may take more 44 than younger men, but they probably climb more skill and less 45 of effort, and they certainly experience equal enjoyment. 26. [A]for [B]in [C]to [D] of 27.
