21、 Co(总题数：3，分数：3.00)Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bone or horn, metal knives and more recently, rubber and plastic and that was where we stuck, in surgical instrument terms, for many years. In the 1960s a new tool was developed, one which

22、was, first of all, to be of great practical use to the armed forces and industry, but which was also, in time, to revolutionize the art and science of surgery. The tool is the laser and it is being used by more and more surgeons all over the world, for a very large number of different complaints. Th

23、e word laser means; light amplification by stimulated emission of radiation. As we all know, light is hot, any source of light-from the sun itself down to a humble match burning-will give warmth. But light is usually spread out over a wide area. The light in a laser beam, however, is concentrated. T

24、his means that a light with no more power than that produced by an ordinary electric light bulb becomes intensely strong as it is concentrated to a pinpoint-sized beam. Experiments with these pinpoint beams showed researchers that difficult energy sources produce beams that have a particular effect

25、on certain living cells. It is now possible for eye surgeons to operate on the back of the human eye without harming the front of the eye, simply by passing a laser beam right through the eyeball. No knives, no stitches(刀口缝合), no unwanted damage -a true surgical wonder. Operations which once left pa

26、tients exhausted and in need of long period of recovery time now leave them feeling relaxed and comfortable. So much more difficult operations can now be tried. The rapid development of laser techniques in the past ten years has made it clear that the future is likely to be very exciting. Perhaps so

27、me cancers will be treated with laser in a way that makes surgery not only safer but also more effective. Altogether, tomorrow may see more and more information coming to light on the diseases which can be treated medically. （分数：1.00）(1).Which of the following would be appropriate to describe the in

28、struments for surgical operations up until 1960s?（分数：0.20）A.Traditional.B.Simple.C.Remarkable.D.Basic.(2).What do we find after the development of the laser in the 1960s?（分数：0.20）A.Industrial revolution brought surgery changed greatly.B.Medical help became available for industrial workers.C.The stud

29、y of art went through a complete revolution.D.Human beings methods in surgery changed greatly.(3).The reason why the laser beam is very strong is that_.（分数：0.20）A.it is artificially illuminated (照亮)B.it is made up of a concentrated beam of lightC.it sends out heat in all directionsD.its heat is incr

30、eased by the heat of the sun(4).After the use of the laser beam, surgeons can perform operations which_.（分数：0.20）A.leave the patients with negative effectsB.can treat only human eye diseaseC.do little damage to the patients themselvesD.make the patients need a long time to recover(5).The rapid devel

31、opment of laser techniques has meant that_.（分数：0.20）A.surgery is likely to improve considerablyB.in another ten years we shall be able to cure cancerC.in future all the diseases can certainly be curedD.operations will be performed more complicatedly in the futureThe way people hold to the belief tha

32、t a fun-filled, pain-free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness, then pain must be equal to unhappiness. But in fact, the opposite is true; more often than not things that lead to happiness involve some pain.

33、 As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment, self-improvement. Ask a bachelor why he resists marriage even though he finds d

34、ating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment, for commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features. Couples w

35、ith infant children are lucky to get a whole nights sleep or a three-day vacation. I dont know any parent who would choose the word “fun“ to describe raising children. But couples who decide not to have children will never know the joys of watching a child grow up or of playing with a grandchild. Un

36、derstanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do no

37、thing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all. （分数：1.00）(1).According to the author, a bachelor resists marriage chiefly because he_.（分数：0.20）A.is reluctant to ta

38、ke on family responsibilitiesB.believes that life will be more cheerful if he remains singleC.finds more fun in dating than in marriageD.fears it will put an end to all his fun adventure and excitement(2).Raising children, in the authors opinion, is a_.（分数：0.20）A.moral dutyB.thankless jobC.rewarding

39、 taskD.source of inevitable pain(3).From the last paragraph, we learn that envy sometimes stems from_.（分数：0.20）A.hatredB.misunderstandingC.prejudiceD.ignorance(4).To understand what true happiness is, one must_.（分数：0.20）A.have as much fun as possible during ones lifetimeB.make every effort to libera

40、te oneself from painC.put up with pain under all circumstancesD.be able to distinguish happiness from fun(5).What is the author trying to tell us?（分数：0.20）A.Happiness often goes hand in hand with pain.B.One must know how to attain happiness.C.It is important to make commitments.D.It is pain that lea

41、ds to happiness.Sleep is part of a persons daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you first drift off into slumber, your eyes will roll about a bit, your temperature will dro

42、p, your muscles will relax, and your breathing will slow and become quite regular. Your brain waves slow down a bit, too, with the alpha rhythm of rather fast waves predominating for the first few minutes. This is called stage 1 sleep. For the next half hour or so, as you relax more and more, you wi

43、ll drift down through stage 2 and stage 3 sleep. The lower your stage of sleep, the slower your brain waves will be. Then, about 40 to 60 minutes after you lose consciousness, you will have reached the deepest sleep of all. Your brain waves will show the large slow waves that are known as the delta

44、rhythm. This is stage 4 sleep. You do not remain at this deep fourth stage all night along, but instead about 80 minutes after you fall into slumber, your brain activity level will increase again slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your e

45、yes will begin to dart around under your closed eyelids as if you were looking at something occurring in front of you. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep. It is during REM sleep that most dreams seem to occur. Provided that you do not wake up dur

46、ing the first REM sleep period, your body will soon relax again, your breathing will grow slow and regular once more, and you will slip gently back from stage 1 to stage 4 sleep only to rise once again to the surface of near consciousness some 80 minutes later. （分数：1.00）(1).Which of the following do

48、ge 4.(3).It can be inferred from the passage that stages of sleep are primarily classified according to_.（分数：0.20）A.breathing rhythmsB.muscular movementC.dreaming patternsD.brain wave activity(4).According to the passage, which of the following is NOT a characteristic of REM sleep?（分数：0.20）A.The eye

49、s dart around.B.It lasts 8 to 15 minutes.C.The delta rhythm is present.D.The sleeper dreams.(5).After how many minutes does an average person repeat the sleep cycle?（分数：0.20）A.8 to 15 minutes.B.30 minutes.C.40 to 60 minutes.D.80 minutes.五、Part B(总题数：1，分数：1.00)As any business owner knows, its not easy to keep going when the going gets tough.
