9、数：4，分数：40.00)Text 1Among Bloombergs web pages on April 7th appeared a story that looked ordinary enough: PairGain, an American telecom equipment manufacturer, was to be bought by an Israeli company for about twice its market value. The companys stock price, predictably, rocketed from $8.50 to$11.13.

10、 All fine and normalexcept that the story wasnt true. Somebody had copied Bloombergs logo and layout and posted a bogus report on the Bloomberg site. When Pair Gain queried the report, it was taken off, and the share price crashed again. Bloomberg is now suing unnamed parties who posted the page.As

11、more and more of life moves on to the Internet, so the difficulty of distinguishing fact from fiction on it becomes more and more of a worry. This problem springs from the Internets central virtue: low barriers to entry. In the real world, being a publisher costs a great deal of money. You have to h

12、ave manufacturing facilities and distribution networks. So real-world publishers have a great deal invested in their reputations and consequently need to be careful about what they print.On the Internet, being a publisher costs next to nothing. Many Internet publishers, therefore, have little to los

13、e from printing untruths and plenty to gain in notoriety if the story they put out is sensational enough. Whats more, faking the real-world newspaper, which has to be both manufactured and distributed, would be next to impossible; faking an Internet page is dead easy.Not all the efforts of the lower

14、ing of the barriers to entry are bad. Big, established newsorganisations can be too cautious and too protective of their more powerful sources. Many scandals have been unearthed first by outsiders with scrappy news sheets and little to lose by way of influential contacts. The Internet is a golden ag

15、e for what used to be the newsletter. The downside is the ease with which error spreads.Rarely, though, falsehood takes the form of international fraud, more often it appears as malicious gossip, slovenly reporting and Chinese whispers. Last year everybody on the Internet knew that Tommy Hilfiger, a

16、 fashion designer, had made racist comments on the Operah Winfrey Show. Except that he didnt. Pierre Salinger, former television newsman, claimed at a news conference that TWA 800, a passenger plane that crashed into the Atlantic killing all aboard in 1996, had been downed by a missileall on the bas

17、is of a web page of dubious origin. Mary Schmich of the Chicago Tribune wrote her column one week as a spoof graduation speech. Somehow this column became tagged on the web, as Kurt Vonneguts commencement speech at MIT.Cyberspace can also be risky, for now, because even sophisticated people can be g

18、ullible about what they read there. This may be because of a lag between technology and perception. Smartly produced pages, and things on screens, impress us with an authority that springs from the resources needed to produce them in the old paper medium. Perhaps everyone should be more worldly wise

19、 about what can turn up on the web.（分数：10.00）(1).The Bloomberg incident in the first paragraph is a case of _.（分数：2.00）A.malicious gossipB.slovenly reportC.Chinese whisperD.international fraud(2).The difference between a real-world publisher and an Internet publisher is that _.（分数：2.00）A.the real-wo

20、rld publisher enjoys low barrier entryB.the Internet publisher is notorious for being untruthfulC.the real-world publisher is too cautious about their investmentD.the Internet publisher enjoys easy access and low costs(3).The falsehood that we often find on the Internet proves that _.（分数：2.00）A.the

21、Internet has nothing to lose if error occursB.the Internet publisher is only a newsletter publisherC.the Internet news report has no powerful sourcesD.the Internet is a totally unreliable news media(4).The lag between technology and perception in the last paragraph probably means that _.（分数：2.00）A.p

22、aper medium publication is far behind Internet publicationB.smartly produced pages appeal to peoples perceptionC.the Internet page sometimes has a deceptive appearanceD.printing techniques acquire authority from necessary sources(5).The author seems to believe that one should _ what one reads in Int

23、ernet news.（分数：2.00）A.rejectB.watchC.acceptD.appreciateText 2The modern cult of beauty is a success in so far as more women retain their youthful appearance to a greater age than in the past. “Old ladies“ are already becoming rare. In a few years, we may well believe, they will be extinct. White hai

24、r and wrinkles, a bent back and hollow cheeks will come to be regarded as medievally old-fashioned. The crone of the future will be golden, curly and cherry-lipped, and slender. This desirable consummation will be due in part to skin foods and injections of paraffin-wax, facial surgery, mud baths, a

25、nd paint, in part to improved health, due in its turn to a more rational mode of life. Ugliness is one of the symptoms of disease, beauty of health. In so far as the campaign for beauty is also a campaign for more health, it is admirable and, up to a point, genuinely successful.Beauty that is merely

26、 the artificial shadow of these symptoms of health is intrinsically of poorer quality than the genuine article. Still, it is a sufficiently good imitation to be sometimes mistakeable for the real thing. The apparatus for mimicking the symptoms of health is now within the reach of every moderately pr

27、osperous person; the knowledge of the way in which real health can be achieved is growing, and will in time, no doubt, be universally acted upon. When that happy moment comes, will every woman be beautifulas beautiful, at any rate, as the natural shape of her features, with or without surgical and c

28、hemical aid, permits?The answer is emphatically: No. For real beauty is as much an affair of the inner as of the outer self. The beauty of a porcelain jar is a matter of shape, of color, of surface texture. The jar may be empty or tenanted by spiders, full of honey or stinking slimeit makes no diffe

29、rence to its beauty or ugliness. But a woman is alive, and her beauty is therefore not skin deep. The surface of the human vessel is affected by the nature of its spiritual contents. I have seen women who, by the standards of a connoisseur of porcelain, were ravishingly lovely. Their shape, their co

30、lour, their surface texture were perfect. And yet they were not beautiful. For the lovely vase was either empty or filled with some corruption. Spiritual emptiness or ugliness shows through. And conversely, there is an interior light that can transfigure forms that the pure aesthetician would regard

31、 as imperfect or downright ugly.There are numerous forms of psychological ugliness. There is an ugliness of stupidity, for example, of unawareness (distressingly common among pretty women). An ugliness also of greed, of lasciviousness, of avarice. All the deadly sins, indeed, have their own peculiar

32、 negation of beauty. On the pretty faces of those especially who are trying to have a continuous “good time“, one sees very often a kind of bored sullenness that ruin all their charm. I remember in particular two young American girls I once met in North Africa. Form the porcelain specialists point o

33、f view, they were extremely beautiful. But a sullen boredom was so deeply stamped into their fresh faces, their gait and gestures expressed so weary a listlessness, that it was unbearable to look at them. These exquisite creatures were positively repulsive.（分数：10.00）(1).Because of skin foods, paraff

34、in wax, facial surgery, mud-baths and paint, _.（分数：2.00）A.wrinkles and hollow cheeks will not be foundB.the desirable consummation will be achievedC.curly hair will look medievally old-fashionedD.the elderly women will no longer be able to exist(2).In the second paragraph, beauty is talked about as

35、_.（分数：2.00）A.an artificial shadow of a genuine articleB.an apparatus for achieving good healthC.the poor imitation of true inner healthD.the good knowledge of health and disease(3).The example of the porcelain jar illustrate the _.（分数：2.00）A.importance of shape, color and textureB.ugliness of spider

36、s and stinking slimeC.connection between inner and outer selfD.gap between appearance and contents(4).The two American girls offer an example of what the author calls _.（分数：2.00）A.unawarenessB.greedC.deadly sinsD.stupidity(5).The author probably writes this article to _.（分数：2.00）A.praise beauty camp

37、aigns successB.demonstrate the improved living standardsC.suggest the importance of inner qualitiesD.predict the future of beauty industryText 3The marvelous telephone and television network that has now enmeshed the whole world, making all men neighbors, cannot be extended into space. It will never

38、 be possible to converse with anyone on another planet. Even with todays radio equipment, the messages will take minutessometimes hourson their journey, because radio and light waves travel at the same limited speed of 186,000 miles a second.Twenty years from now you will be able to listen to a frie

39、nd on Mars, but the words you hear will have left his mouth at least three minutes earlier, and your reply will take a corresponding time to reach him. In such circumstances, an exchange of verbal messages is possiblebut not a conversation.To a culture which has come to take instantaneous communicat

40、ion for granted, as part of the very structure of civilized life, this “time barrier“ may have a profound psychological impact. It will be a perpetual reminder of universal laws and limitations against which not all our technology can ever prevail. For it seems as certain as anything can be that no

41、signalstill less any material objectcan ever travel faster than light.The velocity of light is the ultimate speed limit, being part of the very structure of space and time. Within the narrow confines of the solar system, it will not handicap us too severely. At the worst, these will amount to twenty

42、 hoursthe time it takes a radio signal to span the orbit of Pluto, the outer-most planet.It is when we move out beyond the confines of the solar system that we come face to lace with an altogether new order of cosmic reality. Even today, many otherwise educated menlike those savages who can count to

43、 three but lump together all numbers beyond fourcannot grasp the profound distinction between solar and stellar space. The first is the space enclosing our neighbouring worlds, the planets; the second is that which embraces those distant suns, the stars, and it is literally millions of times greater

44、. There is no such abrupt change of scale in the terrestrial affairs.Many conservative scientists, appalled by these cosmic gulfs, have denied that they can ever be crossed. Some people never learn; those who sixty years ago scoffed at the possibility of flight, and ten years ago laughed at the idea

45、 of travel to the planets, are now quite sure that the stars will always be beyond our reach. And again they are wrong, for they have failed to grasp the great lesson of our agethat if something is possible in theory, and no fundamental scientific laws oppose its realization, then sooner or later it

46、 will be achieved.One day we shall discover a really efficient means of propelling our space vehicles. Every technical device is always developed to its limit and the ultimate speed for spaceships is the velocity of light. They will never reach that goal, but they will get very near it. And then the

47、 nearest star will be less than five years voyaging from the earth.（分数：10.00）(1).For light to travel across the solar system, it will take _.（分数：2.00）A.a yearB.nearly a dayC.two monthsD.thirty minutes(2).The fact that it will never be possible to converse with someone on another planet shows that .（

48、分数：2.00）A.radio messages do not travel fast enoughB.no object can ever travel faster than lightC.western culture has a special idea of communicationD.certain universal laws cannot be prevailed against(3).Confronted with the new order of cosmic reality, many educated men _.（分数：2.00）A.become ignorant

49、savage againB.find the “time barrier“ unbearableC.will not combine solar and stellar spaceD.cannot adapt to the abrupt change of scale(4).Conservative scientists who deny that cosmic gulfs can ever be crossed _.（分数：2.00）A.will laugh at the very idea of flightB.will learn a lesson as they did ten years agoC.will find space travel beyond their reachD.will oppose the fundamental scientific laws(5).The author of the passage, readers can infer, intends to show _.（分数：2.00）A.the limitations of o
