21、 its orbit draws it closer to earth, and its presence in the night sky is a constant reminder of what might be. last summer, it came within 34.6 million miles of earth, its nearest approach in almost 60,000 years. only venus is closer, and with an average temperature of about 850 degrees, it is not

22、welcoming. in contrast, mars is pleasantly cool, from about 200 degrees below zero right up to freezing. from the presence of water and relatively temperate climate comes another powerful attraction. “the fascination with mars centers around the issue of life,” dr. zubrin said. “mars is key to answe

23、ring that critical question, is there life somewhere other than earth?” dr. louis d. friedman, executive director of the planetary society, said, “the fundamental question people want answered is where am i from and where am i going?” he added, “mars can tell us about the origin of life and the dest

24、iny of life. finding evidence of past or present life, even if only primitive microbes, would mean that life did not occur only on earth”, he said. “and”, he said, “mars is the only planet we know of that humans have a chance of colonizing to prove they will not be forever earth-bound.” “mars become

25、s the experiment,” dr. friedman said. “if we cant make it on mars, then earth is our limit and we are going to have to re-examine our relationship to our home planet.” (1)mars is the obvious first choice for travel to other planets, because_. 本题2分 正确答案：b (a) mars is cold and hostile (b) the environm

30、 正确答案：c (a) entertaining (b) imaginative (c) scientific (d) humorous 42. for over a decade, the technique of distraction has been researched and successfully applied in clinical practice in order to reduce pain associated with certain medical procedures. distraction techniques are based on the patie

31、nts limited capacity for attention, resulting in a reduction in the patients attention to the stimulus and therefore a reduction in the stimulus itself. it was assumed that the ideal distracter would require an optimum amount of attention involving various senses (visual, auditory and kinesthetic),

32、an active emotional involvement, and participation from the patient to compete with the signals of the harmful stimuli. the advanced distraction techniques (adts) recently developed use 3d images combined with dynamic audio stimuli, making the techniques more likely to meet the requirements of an id

33、eal distracter than the traditional distraction methods such as watching a film or playing a simple computer game. the adts simulate real-life situations, and the possibilities are infinite. for example, until now users could choose between taking a flight, driving, downhill skiing, exploring buildi

34、ngs and many more activities. in this study, peer-reviewed publications on adts and pain have been reviewed to determine the clinical effectiveness and importance of using these techniques as an analgesic. the results suggest that the adts can significantly reduce the pain associated with medical tr

35、eatment. the use of such analgesia was clinically revealed in most cases, especially in patients with very high or unbearable levels of pain. it was found that levels of anxiety were reduced during the exposure, and the side effects, such as simulator sickness, were hardly observed at all. we can co

36、nclude that adts are very useful as analgesia, and can reduce the amount of analgesic administered. this new field of study can begin to move forward beyond its current initial phase by placing more emphasis on methodology and psychological aspects. (1)which is not the reason why distraction techniq

37、ues can reduce the patients pain? 本题2分 正确答案：a (a) because distraction techniques can remove the pain out of the patients body. (b) because distraction techniques are based on the patients limited capacity for attention. (c) because distraction techniques can cause a reduction in the patients attenti

38、on to the stimulus and therefore a reduction in the stimulus itself. (d) because distraction techniques would require various senses, an active emotional involvement, and participation from the patient to compete with the signals of the harmful stimuli. (2)that adts is better than the traditional di

39、straction methods because _. 本题2分 正确答案：c (a) adts include watching a film or playing a simple computer game. (b) adts require people to take a flight, driving , downhill skiing, exploring buildings, etc. (c) adts use 3dimages combined with dynamic audio stimuli. (d) adts are used in real-life situat

40、ions. (3)according to para. 4, when adts are used, which of the following will not happen? 本题2分 正确答案：a (a) the pain associated with medical treatment has completely gone. (b) levels of anxiety were reduced during the exposure. (c) the side effects, such as simulator sickness, were hardly observed at

41、 all. (d) adts can significantly reduce the pain relevant to medical treatment. (4)from the last paragraph, we know that_. 本题2分 正确答案：b (a) the effect of adts are the same as that of analgesia. (b) we can reduce the amount of analgesia with the help of adts. (c) we can replace analgesia with adts. (d

42、) we have already achieved success in the study of distraction techniques. (5)this passage mainly talks about_ 本题2分 正确答案：a (a) distraction techniques that help ease pain during medical treatment. (b) the relation between adts and traditional distraction methods. (c) the advantages of using adts over

43、 analgesic. (d) the difference between adts and traditional distraction methods. 43. how can we get rid of garbage (垃圾)? do we have enough energy sources to meet out future energy needs? these are two important questions that many people are asking today. some people think that we might be able to s

44、olve both problems at the same time. they suggest using garbage as an energy source. for a long time people have buried garbage, or dumped (倾倒) it on empty land. now while empty land is getting scarce, more and more garbage is being produced each year. fortunately, garbage can be a good fuel (燃料) to

45、 use. the things in garbage do not look like coal, petroleum (石油), or natural gas; but they are chemically similar to these fossil fuels. as we use up our fossil-fuel supplies, we might be able to use garbage as an energy source. burning garbage is not a new idea. some cities in europe and america h

46、ave been burning garbage is used to boil water. the steam that is produced is used to make electricity or to heat nearby buildings. in paris, france, some power plants burn almost 2 million tons of the citys garbage each year. the amount of energy produced is the same as would be produced by burning

47、 almost a half million barrels of oil! but there are problems in using garbage as a fuel. some garbage that burns easily, like food scraps (残渣，碎末) and paper, must be separated from metals, glass, and other materials that do not burn easily. this separation process is normally costly. another problem

48、 is that burning garbage can pollute the air. our fossil fuel supplies are limited. burning garbage might be one kind of energy source that we can use to help meet our energy needs. this method could also reduce the amount of garbage piling up on the earth. (1)burning garbage can solve two problems

49、_. 本题2分 正确答案：a (a) the shortage of energy and too much garbage on the earth. (b) the shortage of energy and the shortage of empty land for holding garbage. (c) air pollution and the shortage of fossil fuel. (d) air pollution and the shortage of energy. (2)according to the passage, which of the follo

50、wing statements is not true? 本题2分 正确答案：d (a) the steam produced is used to make electricity. (b) the heat produced is used to boil water. (c) the steam produced is used to heat buildings. (d) the garbage burned is turned into fossil fuels. (3)according to the passage, which kind of garbage can be bu

51、rnt directly? 本题2分 正确答案：b (a) metals and paper. (b) food scraps and paper (c) glass and food scraps. (d) metals and glass. (4)garbage is similar to _ chemically. 本题2分 正确答案：b (a) natural gas (b) fossil fuels (c) metals (d) glass (5)which of the following can be the best title for the passage? 本题2分 正确

52、答案：c (a) environmental protection (b) use of garbage (c) garbage-an energy source (d) garbage disposal 44. do you forget to turn off the lights and heaters when you go out of a room? in 2040 it will not matter. they will turn themselves offand on again when you return. you will choose the temperatur

53、e for each room, the lighting and the humidity. a sensor will detect the presence of a human (and, with luck, ignore the dog!) and turn the systems on, and when the humans leave it will turn them off again. the sensors will work through the central home computer, and they will do much more than just turn the fires and lights on and off for you. th
