It may be walking, cycling or swimming

18、 in winter, or skating or skiing. It may be a game of some kind football, hockey, golf or tennis. It may be 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 hi

19、gh mountains? This astonishment is caused, probably, by the difference between mountaineering and other forms of activity 【30】 which men give their leisure. Mountaineering is a sport and not a game. There are no man-made roles, as there are for 【31】 games as golf and football. There are, of course,

20、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 use their own 【34】 If we 【35】 mountaineering with other more familiar sports, we might think that one bi

21、g difference is 【36】 mountaineering is not a“ team work“. We should be mistaken in this. There are, it is true, no “matches“ 【37】 “teams“ of climbers, but when climbers are on a rock face linked by a rope on which their lives may 【38】 ,there is obviously teamwork. A mountain climber knows that he ma

22、y have to fight forces that are stronger and more powerful than man. He has to fight 【39】 of nature. His sport requires high mental and 【40】 qualities. A mountain climber 【41】 to improve in skill year after year. A skier is probably past his best by the age of thirty, and most international tennis c

23、hampions 【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 with more skill and less 【45】 of effort, and they certainly experience equal enjoyment. （分数：1.00）A.forB.in

Lilleheis techniques for the first time allowed the

27、 patient to be operated on while blood was supplied to the patient from a donor. Today “open heart“ surgery ,using more complicated methods and bionic devices, is common in the United States. Important technological advances such as those already mentioned have encouraged scientists to develop the a

28、rtificial heart. Early in 1983,in its first use by a human patient, a medical team at the University of Utah Medical Center replaced the diseased heart by a Jarvik-7. The world watched amazed as television pictures of Dr. Clark showed him as he improved steadily after the surgery. His continued life

29、 demonstrated that a bionic device could imitate the action and function of a healthy heart. Dr. Clark lived for 112 days. Life-like or bionic machines have existed for several centuries. The development of tools by man s ancestors is a good example of the application of bionics to extend human capa

30、bilities. Modern bionic research is especially involved in prosthetics devices that substitute for, or replace lost or diseased body parts such as arms ,legs ,and eyes. Recent advances in electronics have enabled scientists to make better use of electrical impulses in the control of prosthetic devic

31、es. One interesting research project is the development of an artificial eye in which video signals are transformed into light patterns that are sent into nerve receptors in the patient. The future for applied bionics seems to be promising. Existing bionic devices will become smaller, faster, and mo

32、re effective. The artificial heart used for Dr. Clark is only one of experimental replacement devices. It is likely to be joined in the future by replacements for other internal systems or organs. Bionic livers, stomachs, and lungs are not impossibilities! （分数：1.00）(1).Which of the following does th

33、is passage mainly discuss?（分数：0.20）A.The application of bionics.B.The first “open heart“ surgery.C.The development of the artificial heart.D.The future of applied bionics.(2).According to the passage, it was Dr. W. Lillehei that _.（分数：0.20）A.first developed applied bionicsB.was the first to operate

34、on the heart of a patientC.developed the artificial heartD.used more sophisticated methods to do “open heart“ surgery(3).By “Dr. Clark lived for 112 days“ ,the author most probably means that _.（分数：0.20）A.the replacement of Dr. Clark s heart was a failureB.there was still a long way to go in applied

35、 bionicsC.applied bionics was promisingD.the first artificial heart was most effective(4).The control of artificial devices is improving because _.（分数：0.20）A.video signals can be transformed into light patternsB.bionic machines have existed for centuriesC.artificial devices such as arms, legs and ey

36、es require better control than bionic machinesD.science has made great advances in electronics(5).The author s attitude towards applied bionics is _.（分数：0.20）A.criticalB.approvingC.objectiveD.questioningIn California the regulators, the utilities and the governor all want the Federal Energy Regulato

37、ry Commission to cap spot (现货的) market prices. The Californians claim it will rein in outrageous prices. Federal regulators have refused. The battle is on. Governor Gray Davis says, “Im not happy with the Federal Regulatory Commission at all. Theyre living in an ivory tower. If their bills were goin

38、g up like the people in San Diego, they would know that this is a real problem in the real world. “ As part of deregulation, price caps were removed to allow for a free market. Timing is everything; natural gas prices had already skyrocketed. Demand was high from Californias booming economy. No new

39、power plants had been built here in ten years, and power producers had the right to hike prices along with demand. And hike them they did. Loretta Lynch of the Public Utilities Commission says, “ This commission and all of California was beating down the door of federal regulators to say, * Help us

40、impose reasonable price caps to help to keep our market stable. Federal regulators did ask for longer-term contracts between power producers and the utilities to stabilize prices. The federal commission, unavailable for comment on this story, released a recent statement defending its position not to

41、 re-regulate. Federal Energy Regulatory Commission Dec. 15, 2000: “The commissions intention is to enable the markets to catch up the current supply and demand problems and not to reintroduce command and control regulation that has helped to produce the current crisis. “ Some energy experts believe

42、that, without temporary price caps, the crisis will continue. Severin Borenstein of the U. C. Energy Institute says, “Some federal regulators have a blind commitment to making the market work and I think part of the problem is they really dont understand whats going on. “ Gary Ackerman of the Wester

43、n Power Trading Forum says, “ Hes dead wrong about that. The federal regulators understand far better than any individual state that, though it might be painful and it certainly is painful in California, price caps dont work. They never work. “ （分数：1.00）(1).The battle between Californians and federa

44、l regulators is about_.（分数：0.20）A.control over the price of powerB.necessity of removing price capsC.hiking the energy prices in CaliforniaD.a regulation concerning power supply(2).Governor Gray Davis was dissatisfied with the Federal Regulatory Commission because they_.（分数：0.20）A.did not know what

45、the real problem wasB.were living an easy life in an ivory towerC.could not experience the life in San DiegoD.turned a blind eye to the situation in California(3).The Federal Commission uncapped the energy price with the intention to_.（分数：0.20）A.help Californias economy booming steadilyB.prevent pow

46、er price from going up any furtherC.enable the market to deal with supply and demand problemsD.have contracts signed between power producers and the utilities(4).To help keep prices from going higher, people and groups in California_.（分数：0.20）A.imposed reasonable price capsB.beat down the door of fe

47、deral regulatorsC.urged the federal authorities to take actionD.struggled against federal policy to hike prices(5).Energy experts against price caps believe that_.（分数：0.20）A.the present situation in California will continue unless there is price controlB.the current crisis is partly attributed to pr

48、evious command and control policyC.price caps can temporarily solve energy problems an individual state meets withD.they do understand what is going on in California and will take proper measuresIn England recently three foreign gentlemen approached a bus stop. They studied the information on the si

49、gn attached to the concrete post and decided which bus to take. About five minutes later the bus they wanted came along. They prepared to board it. Suddenly there was a clamor behind them. People rushed onto the bus and tried to push them out of the way. Someone shouted insulting remarks about foreigners. The bus conductor came rushing down the stairs to see what all the trouble was about. The three foreign gentlemen looked puzzled and embarras
