12、eving immediate payroll savings of $200 million. Additional savings would follow in each of 10 years afterward. The plan attracted the rapt attention of the top executives, 9 the chairman and a vice chairman. The ambitious original scheme was scaled down when the company was forced to slash its annu

Although the first units cost more, Marriott eventually expects to buy robots 11 $20,000 a piece, 12 four time

Robots might eventually be used for 14 tasks as cutting the grass on golf 15 or perhaps placing silverware on trays.（分数：30.00）六、Section Reading Co(总题数：0，分数：0.00)七、Part A(总题

15、数：1，分数：10.00)As we age, the lenses in our eyes lose their flexibility (灵活性). Eventually, most of us need glasses for reading. The problem is that reading glasses will not work for seeing distant object, so we need bifocals, trifocals or multiple pairs of spectacles. This soon may change if a new dev

16、elopment by The Egg Factory proves its worth. Optometrist (验光师，配镜师) Ronald D. Blum, head of The Egg Factory and its subsidiary eVision LLC, is leading the development of glasses that automatically change their focus as the wearer looks at objects at different distances. The eVision researchers claim

17、 to have produced a “crude“ working prototype. The idea is based on patented technology from Motorola Inc. that describes eyeglasses with lenses that change their refractive (反射的，反光的) index when a voltage is applied. The eVision“s lenses are broken up into pixels that also respond to voltage by chan

18、ging the refractive index. The glasses would carry a small onboard computer and infrared (红外线的) rangefinder (测距仪) that would determine the focal distance and transmit this information to the computer, which would adjust the refractive index of the pixels accordingly. Besides the ease of handling onl

19、y one pair of glasses, the system offers people two other benefits. Users could cut down on the number of visits to the optician because a prescription change would be accomplished by changing the computer program. In addition, the system theoretically could give users “super vision“ by compensating

20、 for imperfections in their vision in much the same way that adaptive optics allow astronomers to compensate for atmospheric turbulence. The eVision has several challenges to overcome before the spectacles are ready for market. The lens materials must transmit as much light as possible, and the elec

21、tronics and chemical contacts must be nearly transparent. The researchers must shrink the computer and IR rangefinder to fit comfortably on a pair of glasses. Another packaging challenge is style. Most consumers will not wear bulky “geek (怪的) glasses“ But eVision is undaunted. It believes the techno

22、logy has the potential to generate more than $1 billion annually within five years.（分数：10.00）(1).What is the best title for this passage?（分数：2.00）A.Magic GlassesB.Glass DevelopmentC.Autofocus Glasses under DevelopmentD.Imaginative Glasses(2).We can infer from the passage that _.（分数：2.00）A.Human bein

23、g“s eyes can easily adjust the focus at any ageB.The Egg Factory claims to have produced a “crude“ working prototypeC.The cardinal principle of developing the new type of glass is that lenses can change their refractive index when a voltage is appliedD.If the new glasses appear on the market, it wil

24、l be very popular with the consumers(3).The challenges to realize the autofocus glasses include the following except _.（分数：2.00）A.the computer and IR rangefinder must be minimized to fit comfortably on a pair of glassesB.the electronics and chemical contacts must be made as light as possibleC.the le

25、ns material must transmit as much light as possibleD.as for packaging, the biggest challenge is style, because most consumers dislike heavy and strange-looking glasses(4).The word“ undaunted“ in the last paragraph probably means _.（分数：2.00）A.bold and resoluteB.discouraged and disappointedC.confident

26、 and vigorousD.trustful and honest(5).The new type of glasses will bring about the following benefits to consumers EXCEPT _.（分数：2.00）A.It“s unnecessary for the consumers to take multiple pairs of spectacles, for one is enoughB.The number of visits to the optician will be reduced greatlyC.Users“ visi

27、on can be“ bettered“ because the glasses can make up for the drawbacks of their vision in much the same way that adaptive optics allow astronomers to compensate for atmospheric turbulenceD.The manufacturer will make a lot of profits八、Part B(总题数：1，分数：10.00)The early electronic computer did not have m

28、uch going for it except a prodigious memory and some good math skills, but today the best models can be wired up to learn by experience, follow an argument, ask pertinent questions and write pleasing poetry and music. They can also carry on somewhat distracted conversations so convincingly that thei

29、r human partners do not know they are talking to a machine. 1 The proposition seems ridiculous because, for one thing, computers lack the drives and emotions of living creatures. But when drives are useful, they can be programmed into the computer“s brain, just as nature programmed them into our anc

30、estors“ brains as a part of the equipment for survival. For example, computers, like people, work better and learn faster when they are motivated. Arthur Samuel made this discovery when he taught two IBM computers how to play checkers. They polished their game by playing each other, but they learned

31、 slowly. Finally Dr. Samuel programmed in the will to win by forcing the computers to try harderand to think out more moves in advancewhen they were losing. Then the computers learned very quickly. One of them beat Samuel and went on to defeat a champion player who had not lost a game to a human opp

32、onent in eight years. 2 We are still in control, but the capabilities of computers are increasing at a fantastic rate, while raw human intelligence is changing slowly, if at all. Computer power is growing exponentially; it has increased tenfold every eight years since 1946. Four generations of compu

33、ter evolutionvacuum tubes, transistors, simple integrated circuits and today“s miracle chipsfollowed one another in rapid succession, and the fifth generation, built out of such esoteric devices as bubble memories and Josephson junctions, will be on the market in the 1980s. In the 1990s, when the si

34、xth generation appears, the compactness and reasoning power of an intelligence built out of silicon will begin to match that of the human brain. 3 The partnership will not last very long. Computer intelligence is growing by leaps and bounds, with no natural limit in sight. But human evolution is a n

35、early finished chapter in the history of life. The human brain has not changed, at least in gross size, in the past 100 000 years, and while the organization of the brain may have improved in that period, the amount of information and wiring that can be crammed into a cranium of fixed size is limite

36、d. 4 The history of life suggests that the evolution of the new species will take about a million years. Since the majority of the planets in the universe are not merely millions but billions of years older than the earth, the life they carryassuming life to be common in the cosmos must long since h

37、ave passed through the stage we are about to enter. 5 In any event, our curiosity may soon be satisfied. At this moment a shell of TV signals carrying old I Love Luky programs and Tonight shows is expanding through the cosmos at the speed of light. That bubble of broadcasts has already swept past ab

38、out 50 stars like the sun. Our neighbors know we are here, and their replies should be on the way. In another 15 or 20 years we will receive their message and meet our future. Let us be neither surprised nor disappointed if its form is that of Artoo Detoo, the bright, personable canister packed with

39、 silicon chips. A. By that time, ultra-intelligent machines will be working in partnership with our best minds on all the serious problems of the day, in an unbeatable combination of brute reasoning power and human intuition. What happens after that? Dartmouth President John Kemeny, a pioneer in com

40、puter usages, sees the ultimate relation between man and computer as a symbiotic union of two living species, each completely dependent on the other for survival. The computera new form of life dedicated to pure thoughtwill be taken care of by its human partners, who will minister to its bodily need

41、s with electricity and spare parts. Man will also provide for computer reproduction, as he does today. In return, the computer will minister to our social and economic needs. Child of man“s brain rather than his loins, it will become his salvation in a world of crushing complexity. B. These are amia

42、ble qualities for the computer; it imitates life like an electronic monkey. As computers get more complex, the imitation gets better. Finally, the line between the original and the copy becomes blurred. In another 15 years or sotwo more generations of computer evolution, in the jargon of the technol

43、ogistswe will see the computer as an emergent form of life. C.A billion years is a long time in evolution; 1 billion years ago, the highest form of life on the earth was a worm. The intelligent life in these older solar systems must be as different from us as we are from creatures wriggling in the o

44、oze. Those superintelligent beings surely will not be housed in the more or less human shapes portrayed in Star Wars and Close Encounters of the Third Kind. In a cosmos that has endured for billions of years against man“s mere million, the human form is not likely to be the standard form for intelli

45、gent life. D. Computer Monitoring is most often intended to improve efficiency and effectiveness in the workplace, but with good intentions comes the opportunity for abuse by employers and employees alike. Computer Monitoring in the 21st Century written by a futurist is an exceptional observation as

46、 to what the future may hold for those people who choose to enter the technological field such as industry, commerce, medicine and science. E. Computers match people in some roles, and when fast decisions are needed in a crisis, they outclass them. The human brain has a wiring defect that prevents i

47、t from absorbing several streams of information simultaneously and acting on them quickly. Throw too many things at the brain at one time and it freezes up; it evolved more than 100 000 years ago, when the tempo of life was slower. F. That does not mean the evolution of intelligence has ended on the

48、 earth. Judging by the record of the past, we can expect that a new species will arise out of man, surpassing his achievements as he has surpassed those of his predecessor, Homo erectus. Only a carbon-chemistry chauvinist would assume that the new species must be man“s flesh-and-blood descendants, with brains housed in fragile shells of bone. The new kind of intelligent life is more likely to be made of silicon.（分
