1、2019 四級仔細閱讀題精選練習 20 套(2)Part II Reading Comprehension(35 minutes)Directions : There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B) , C) and D). You should decide on the best choice and mark the co
2、rresponding letter on the Answer Sheet with a single line through the center.Passage OneQuestions 21 to 25 are based on the following passage.流星)Unless we spend money to spot and prevent asteroids ( 行星 ) now, one might crash into Earth and destroy life as we know it, say some scientists.Asteroids ar
3、e bigger versions of the meteoroids ( that race across the night sky. Most orbit the sun far from Earth and don t threaten us. But there are also thousands of 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
4、year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we ll have a way to change its course.Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldnt be cheap.Is it worth it? Two things experts consider
5、when judging any risk re : 1) How likely the event is; and 2) How bad theconsequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare but if one did fall,it would be the end of the world.“If we don t ta
6、ke care ofthese big asteroids, theyll take care of us,” says onescientist.“It s that simple. ”The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth? “The world has less to fear from doomsday (毀滅性的 ) rocksthan from a great nuclear fleet
7、 set against them,” said aNew York Times article.21. What does the passage say about asteroids and meteoroids?A) They are heavenly bodies different in composition.B) They are heavenly bodies similar in nature.C) There are more asteroids than meteoroids.D) Asteroids are more mysterious than meteoroid
8、s.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 every 25 years.C) Collisions of smaller asteroids with Earth occur more often than expected.D) It s still too early to say whether such a colli
9、sion might occur.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 not 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 v
10、ery unlikely.D) Further research should be done before it is proved applicable.24. We can conclude from the passage that .A) while pushing asteroids off 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
11、 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 collision of asteroids with Earth25. Which of the following best describes theauthor stone in this passage?A) Optimistic. B) Critical. C) Objective. D)
12、 Arbitrary.Passage TwoQuestions 26 to 30 are based on the following passage.Believe it or not, optical illusion (錯覺 ) can cuthighway crashes.Japan is 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 (
13、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 Automobile Association Foundation for Traffic Safety in Washington D.C. is planning to repeat Japans success. Starting next year, the foundation will paint che
14、vrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes.Excessive speed plays a 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 co
15、nduct its tests in areas where speed-related hazards are the greatest curves, exit slopes, traffic circles, and bridges.Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within
16、 months as drivers become used to seeing the painted bars.Chevrons, scientists say, not only give drivers the impression that they are driving faster 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 ac
17、cidents.26. The passage mainly discusses .A) a new way of highway speed controlB) a new pattern for painting highwaysC) a new approach to training driversD) a new type of optical illusion27. On roads painted with chevrons, drivers tend to feel that .A) they should avoid speed-related hazardsB) they
18、are driving in the wrong laneC) they should slow down their speedD) they are approaching the speed limit28. The advantage of chevrons over straight, 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
19、attractive29. The American Automobile Association Foundation for Traffic Safety plans to .A) try out the Japanese method in certain areasB) change the road signs across the countryC) replace straight, horizontal bars with chevronsD) repeat the Japanese road patterns30. What does the author say about
20、 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 in a short period of time.C) They are applicable only on broad roads.D) They cannot be applied successfully to traffic circles.Passage ThreeQuestions 31 to 35 are
21、 based on the following passage.Amtrak ( 美國鐵路客運公司 ) was experiencing a downswing in ridership (客運量 ) along the lines comprising its railsystem. Of major concern to Amtrak and its advertising agency DDB Needham, were the long-distance western routes where ridership had been declining significantly. A
22、t one time, trains were the only practical way to cross the vast areas of the west. Trains were fast, very luxurious, and quite convenient compared to other forms of transportation existing at the time. However, times change and the automobile became Americas standard of convenience. Also, air trave
23、l had easily established itself as the fastest method of traveling great distances. Therefore, the task for DDB Needham was to encourage consumers 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 th
24、e west.Two portions of the total market were targeted: 1)anxious fliers those concerned with safety, relaxation, and cleanliness and 2) travel-loversthose viewing themselves asrelaxed, casual, and interested in the travel experience as part of their vacation. The agency then developed a campaign tha
25、t focused on travel experiences such as freedom, escape, relaxation, and enjoyment of the great western outdoors. It stressed experiences gained by using the trains and portrayed western train trips as wonderful adventures.Advertisements showed pictures of the beautiful scenery that could be enjoyed
26、 along some of the more famous western routes and emphasized the romantic names of some of these trains (Empire Builder, etc.). These ads were strategically placed among family-orientedTV shows and programs involving nature and America in order to most effectively reach target audiences. Results wer
27、e impressive. The Empire Builder, which was focused on in one ad, enjoyed a 15 percent increase in profits on its Chicago to Seattle route.31. What s the author s purpose in writing this passage?A) To show the inability of trains to compete with planes with respect to speed and convenience.B) To str
28、ess the influence of the automobile on Americas standard of convenience.C) To emphasize the function of travel agencies in market promotion.D) To illustrate the important role of persuasive communication in changing consumer attitudes.32. It can be inferred from the passage that the drop in Amtrak r
29、idership was due to the fact that .A) trains were not suitable for short distance passenger transportationB) trains were not the fastest 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 an
30、d convenience33. To encourage consumers to travel by train, DDB Needham emphasized .A) the freedom and convenience provided on trainsB) the practical aspects of train travelC) the adventurous aspects of train tripsD) the safety and cleanliness of train trips34. The train ads were placed among family
31、-oriented TV programs involving nature and America because .A) they could focus on meaningful travel experiencesB) they could increase 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 audi
32、ences35. According to the passage, the Empire Builder enjoyed an increase in ridership and profits because .A) the attractiveness 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 adver
33、tised in newspapers and magazines in Chicago and SeattlePassage FourQuestions 36 to 40 are based on the following passage.Why 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 composition afindingthat co
34、uld help rid some processed foods of chemical preservatives.Cream and butter contain pretty much the same substances, so why cream should sour much faster has been a mystery. Both are emulsions tiny globules ( 小球體 ) of one liquid evenly distributed throughout another. The difference lies in whats in
35、 the globules and what s in the surrounding liquid,says Brocklehurst, who led the investigation.In cream, fatty globules drift 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 regio
36、ns of the mixture.“This means thatin cream, the bacteria are free to grow throughout the mixture, ” he says.When the situation 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
37、 nutrients (養(yǎng)料). They also slowly poisonthemselves with their waste products.“In butter, you get aself- limiting system which stops the bacteria growing,” saysBrocklehurst.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 cream, for instance, more like that in butter. The key will be to do this while keeping the salad cream liquid and not turning i
