| 第1、2、3、4、5题：Obviously television has both advantages and disadvantages. In the first place, television is not only a convenient source of entertainment, but also a comparatively cheap one. With a TV set in the family people don’t have to pay for expensive seats at the theatre, the cinema, or the opera .All they have to so is to push a button or turn a knob, and they can see plays, films, operas and shows of every kind. Some people, however, think that this is where the danger lies. The television viewers need do nothing. He does not even have to use his legs if the has a remote control. He makes no choice and exercises, no judgment. He is completely passive and has everything presented to him without any effort in his part. Television, it is often said, keeps one informed about current events and the latest developments in science and politics. The most distant countries and the strangest customs are brought right into one’s sitting room. It could be argued that the radio performs this service as well; but on television everything is much more living, much more real. Yet here again there is a danger. The television screen itself has a terrible, almost physical charm for us. We get so used to looking at the movements on it ,so dependent on its pictures, that it begins to control our lives. People are often heard to say that their television sets have broken down and that they have suddenly found that they have far more time to do things and the they have actually begin to talk to each other again. It makes one think, doesn’t it? There are many other arguments for and against television. We must realize that television itself is neither good nor bad. It is the uses that it is put to that determine its value to society. 51. What is the major function of paragraph 1? A. To arouse the reader’s concern B.

| 第6题：The idea that some groups of people may be more intelligent than others is one of those hypotheses that dare not speak its name. But Gregory Cochran is 1 to say it anyway. He is that 2 bird, a scientist who works independently 3 any institution. He helped popularize the idea that some diseases not 4 thought to have a bacterial cause were actually infections, which aroused much controversy when it was first suggested. 5 he, however, might tremble at the 6 of what he is about to do. Together with another two scientists, he is publishing a paper which not only 7 that one group of humanity is more intelligent than the others, but explains the process that has brought this about. The group in 8 are a particular people originated from central Europe. The process is natural selection. This group generally do well in IQ test, 9 12-15 points above the 10 value of 100, and have contributed 11 to the intellectual and cultural life of the West, as the 12 of their elites, including several world-renowned scientists, 13. They also suffer more often than most people from a number of nasty genetic diseases, such as breast cancer. These facts, 14, have previously been thought unrelated. The former has been 15 to social effects, such as a strong tradition of 16 education. The latter was seen as a (an) 17 of genetic isolation. Dr. Cochran suggests that the intelligence and diseases are intimately 18. His argument is that the unusual history of these people has 19 them to unique evolutionary pressures that have resulted in this 20 state of affairs. 1.

| 第7、8、9、10、11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13、14、15、16、17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 ______ .
