18、d money to spot and prevent asteroids (小行星) now, one might crash into Earth and destroy life as we know it, say some scientists.Asteroids are bigger versions of the meteoroids (流星) that race across the night sky. Most orbit the sun far from Earth and dont threaten us. But there are also thousands of

19、 asteroids whose orbits put them on a collision course with Earth.Buy $50 million worth of new telescopes right now. Then spend $10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, well have a way to change its course.Some s

20、cientists favor pushing asteroids off course with nuclear weapons. But the cost wouldnt be cheap.Is it worth it? Two things experts consider when judging any risk re: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots

21、 of life might strike Earth once every 500,000 years. Sounds pretty rarebut if one did fall, it would be the end of the world. “If we dont take care of these big asteroids, theyll take care of us,” says one scientist. “Its that simple.”The cure, though, might be worse than the disease. Do we really

22、want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday (毀滅性的) rocks than from a great nuclear fleet set against them,” said a New York Times article.21.What does the passage say about asteroids and meteoroids?A) They are heavenly bodies different in composi

23、tion.B) They are heavenly bodies similar in nature.C) There are more asteroids than meteoroids.D) Asteroids are more mysterious than meteoroids.（B）22.What do scientists say about the collision of an asteroid with Earth?A) It is very unlikely but the danger exists.B) Such a collision might occur once

24、 every 25 years.C) Collisions of smaller asteroids with Earth occur more often than expected.D) Its still too early to say whether such a collision might occur.（A）23.What do people think of the suggestion of using nuclear weapons to alter the courses of asteroids?A) It sounds practical but it may no

25、t solve the problem.B) It may create more problems than it might solve.C) It is a waste of money because a collision of asteroids with Earth is very unlikely.D) Further research should be done before it is proved applicable.（B）24.We can conclude from the passage that _.A) while pushing asteroids off

26、 course nuclear weapons would destroy the worldB) asteroids racing across the night sky are likely to hit Earth in the near futureC) the worry about asteroids can be left to future generations since it is unlikely to happen in our lifetimeD) workable solutions still have to be found to prevent a col

27、lision of asteroids with Earth（D）25.Which of the following best describes the authors tone in this passage?A) Optimistic.B) Critical.C) Objective.D) Arbitrary.（C）Passage TwoQuestions 26 to 30 are based on the following passage.Believe it or not, optical illusion (錯(cuò)覺) can cut highway crashes.Japan is

28、 a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent stripes, called chevrons (人字形), painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down.Now the American Automobi

29、le Association Foundation for Traffic Safety in Washington D.C. is planning to repeat Japans success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes.Excessive speed plays a

30、 major role in as much as one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards are the greatestcurves, exit slopes, traffic circles, and bridges.Some studies suggest that stra

31、ight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bars.Chevrons, scientists say, not only give drivers the impression that they are driving faster

32、than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction in highway sped and the number of traffic accidents.26.The passage mainly discusses _.A) a new way of highway speed controlB) a new pattern for painting highwaysC) a new approach to training dri

33、versD) a new type of optical illusion（A）27.On roads painted with chevrons, drivers tend to feel that _.A) they should avoid speed-related hazardsB) they are driving in the wrong laneC) they should slow down their speedD) they are approaching the speed limit（C）28.The advantage of chevrons over straig

34、ht, horizontal bars is that the former _.A) can keep drivers awakeB) can cut road accidents in halfC) will have a longer effect on driversD) will look more attractive（C）29.The American Automobile Association Foundation for Traffic Safety plans to _.A) try out the Japanese method in certain areasB) c

35、hange the road signs across the countryC) replace straight, horizontal bars with chevronsD) repeat the Japanese road patterns（A）30.What does the author say about straight, horizontal bars painted across roads?A) They are falling out of use in the United States.B) They tend to be ignored by drivers i

36、n a short period of time.C) They are applicable only on broad roads.D) They cannot be applied successfully to traffic circles.（B）Passage ThreeQuestions 31 to 35 are based on the following passage.Amtrak (美國(guó)鐵路客運(yùn)公司) was experiencing a downswing in ridership (客運(yùn)量) along the lines comprising its rail sy

37、stem. Of major concern to Amtrak and its advertising agency DDB Needham, were the long-distance western routes where ridership had been declining significantly. At one time, trains were the only practical way to cross the vast areas of the west. Trains were fast, very luxurious, and quite convenient

38、 compared to other forms of transportation existing at the time. However, times change and the automobile became Americas standard of convenience. Also, air travel had easily established itself as the fastest method of traveling great distances. Therefore, the task for DDB Needham was to encourage c

39、onsumers to consider other aspects of train travel in order to change their attitudes and increase the likelihood that trains would be considered for travel in the west.Two portions of the total market were targeted: 1) anxious fliersthose concerned with safety, relaxation, and cleanliness and 2) tr

40、avel-loversthose viewing themselves as relaxed, casual, and interested in the travel experience as part of their vacation. The agency then developed a campaign that focused on travel experiences such as freedom, escape, relaxation, and enjoyment of the great western outdoors. It stressed experiences

41、 gained by using the trains and portrayed western train trips as wonderful adventures.Advertisements showed pictures of the beautiful scenery that could be enjoyed along some of the more famous western routes and emphasized the romantic names of some of these trains (Empire Builder, etc.). These ads

42、 were strategically placed among family-oriented TV shows and programs involving nature and America in order to most effectively reach target audiences. Results were impressive. The Empire Builder, which was focused on in one ad, enjoyed a 15 percent increase in profits on its Chicago to Seattle rou

43、te.31.Whats the authors purpose in writing this passage?A) To show the inability of trains to compete with planes with respect to speed and convenience.B) To stress the influence of the automobile on Americas standard of convenience.C) To emphasize the function of travel agencies in market promotion

44、.D) To illustrate the important role of persuasive communication in changing consumer attitudes.（D）32.It can be inferred from the passage that the drop in Amtrak ridership was due to the fact that _.A) trains were not suitable for short distance passenger transportationB) trains were not the fastest

45、 and most convenient form of transportationC) trains were not as fast and convenient as they used to beD) trains could not compete with planes in terms of luxury and convenience（B）33.To encourage consumers to travel by train, DDB Needham emphasized _.A) the freedom and convenience provided on trains

46、B) the practical aspects of train travelC) the adventurous aspects of train tripsD) the safety and cleanliness of train trips（C）34.The train ads were placed among family-oriented TV programs involving nature and America because _.A) they could focus on meaningful travel experiencesB) they could incr

47、ease the effectiveness of the TV programsC) their profits could be increased by some 15 percentD) most travel-lovers and nervous fliers were believed to be among the audiences（D）35.According to the passage, the Empire Builder enjoyed an increase in ridership and profits because _.A) the attractivene

48、ss of its name and route was effectively advertisedB) it provided an exciting travel experienceC) its passengers could enjoy the great western outdoorsD) it was widely advertised in newspapers and magazines in Chicago and Seattle（A）Passage FourQuestions 36 to 40 are based on the following passage.Wh

49、y does cram go bad faster than butter? Some researchers think they have the answer, and it comes down to the structure of the food, not its chemical compositiona finding that could help rid some processed foods of chemical preservatives.Cream and butter contain pretty much the same substances, so wh

50、y cream should sour much faster has been a mystery. Both are emulsionstiny globules (小球體) of one liquid evenly distributed throughout another. The difference lies in whats in the globules and whats in the surrounding liquid, says Brocklehurst, who led the investigation.In cream, fatty globules drift

51、 about in a sea of water. In butter, globules of a watery solution are locked away in a sea of fat. The bacteria which make the food go bad prefer to live in the watery regions of the mixture. “This means that in cream, the bacteria are free to grow throughout the mixture,” he says.When the situatio

52、n is reversed, the bacteria are locked away in compartments (隔倉室) buried deep in the sea of fat. Trapped in this way, individual colonies cannot spread and rapidly run out of nutrients (養(yǎng)料). They also slowly poison themselves with their waste products. “In butter, you get a self-limiting system whic

53、h stops the bacteria growing,” says Brocklehurst.The researchers are already working with food companies keen to see if their products can be made resistant to bacterial attack through alterations to the foods structure. Brocklehurst believes it will be possible to make the emulsions used in salad c

54、ream, for instance, more like that in butter. The key will be to do this while keeping the salad cream liquid and not turning it into a solid lump.36.The significance of Brocklehursts research is that _.A) it suggested a way to keep some foods fresh without preservativesB) it discovered tiny globule

55、s in both cream and butterC) it revealed the secret of how bacteria multiply in cream and butterD) it found that cream and butter share the same chemical composition（A）37.According to the researchers, cream sours fast than butter because bacteria _.A) are more evenly distributed in creamB) multiply

56、more easily in cream than in butterC) live on less fat in cream than in butterD) produce less waste in cream than in butter（B）38.According to Brocklehurst, we can keep cream fresh by _.A) removing its fatB) killing the bacteriaC) reducing its water contentD) altering its structure（D）39.The word “col

57、onies” (Line 2, Para. 4) refers to _.A) tiny globulesB) watery regionsC) bacteria communitiesD) little compartments（C）40.Commercial application of the research finding will be possible if salad cream can be made resistant to bacterial attack _.A) by varying its chemical compositionB) by turning it into a solid lumpC) while keeping its structure unchangedD) while retaining its liquid form（D）Part III
