8、e in a world in which science has tremendous importance. During their lifetimes it will affect them more and more. In time, many of them will work at jobs that depend heavily on science for example, concerning energy sources, pollution control, highway safety, wilderness conservation, and population

9、 growth, and population growth. As taxpayers they will pay for scientific research and exploration. And, as consumers, they will Be bombarded(受到轰击 ) by advertising, much of which is said to be based on science. Therefore, it is important that children, the citizens of the future, become functionally

10、 acquainted with science with the process and spirit of science, as well as with its facts and principles. Fortunately, science has a natural appeal for youngsters. They can relate it to so many things that they encounter flashlights, tools, echoes, and rainbows. Besides, science is an excellent med

11、ium for teaching far more than content. It can help pupils learn to think logically, to organize and analyse ideas. It can provide practice in communication skills and mathematics. In fact, there is no area of the curriculum to which science cannot contribute, whether it is geography, history, langu

12、age arts, music, or art! Above all, good science teaching leads to what might be called a “scientific attitude“. Those who possess it seek answers through ohserving, experimenting, and reasoning, rather than blindly accepting the pronouncements of others. They weigh evidence carefully and reach conc

13、lusions with caution. While respecting the opinions of others, they expect honesty, accuracy, and objectivity and are on guard against hasty judgments and sweeping generalizations. All children should be developing this approach to solving problems, but it cannot be expected to appear automatically

14、with the mere acquisition of information. Continual practice, through guided participation, is needed. 11 One of the reasons why science is important for children is that many of them will_. （ A） work in scientific research institutions （ B） work at jobs Closely related to science （ C） make the fina

19、60s and 70s, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation worldwide has decreased significantly. A study published recently in the journal

20、Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment

21、at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic(北极的 ) snow were declining. In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were differen

22、t from the ratios of European, Asian and Canadian gasolines and thus enabled scientists to differentiate(区分 ) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States. In a study published in the journal Ambio, scientists found that lead

23、 levels in soil in the Northeasten United States had decreased markedly since the introduction of unleaded gasoline. Many scientists had believed that the lead would stay in soil and snow for a longer period. The authors of the Ambio study examined samples of the upper layers of soil taken from the

24、same sites of30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expeeted. Scientists say both studies demonstrate that certain parts of the ecosystem(生态系统 ) respond rapidly to redu

25、ctions in atmospheric pollution, but that these findings should not be used as a license to pollute. 16 The study published in the journal Nature indicates that _. （ A） the Clean Air Act has not produced the desired results （ B） lead deposits in arctic snow are on the increase （ C） lead will stay in

26、 soil and snow longer than expected （ D） the U.S. is the major source of lead pollution in arctic snow 17 Lead accumulation worldwide decreased significantly after the use of unleaded gas in the U.S._. （ A） was discouraged （ B） was enforced by law （ C） was prohibited by law （ D） was introduced 18 Ho

27、w did scientists discover the source of lead pollution in Greenland? （ A） By analyzing the data published in journals like Nature. （ B） By observing the lead accumulations in different parts of the arctic area. （ C） By studying the chemical elements of soil and snow in Northeastern America. （ D） By

28、comparing the chemical compositions of leaded gasoline used in various countries. 19 The authors of the Ambio study have found that_. （ A） forests get rid of lead pollution faster than expected （ B） lead accumulations in forests are more difficult to deal with （ C） lead deposits are widely distribut

29、ed in the forests of the U.S. （ D） the upper layers of soil in forests are easily polluted by lead emissions 20 It can be inferred from the last paragraph that scientists （ A） are puzzled by the mystery of forest pollution （ B） feel relieved by the use of unleaded gasoline （ C） still consider lead p

30、ollution a problem （ D） lack sufficient means to combat lead pollution 21 In recent years, railroads have been combining with each other, merging into super systems, causing heightened concerns about monopoly. As recently as 1995, the top four railroads accounted for under 70 percent of the total te

31、n-miles moved by rails. Next year, after a series of mergers is completed, just four rail roads will control well over 90 percent of all the freight moved by major rail carriers. Supporters of the new super systems argue that these mergers will allow for substantial cost reductions and better coordi

32、nated service. Any threat of monopoly, they argue, is removed by fierce competition from trucks. But many shippers complain that for heavy bulk commodities traveling long distances, such as coal, chemicals, and grain, trucking is too costly and the railroads therefore have them by the throat. The va

33、st consolidation within the rail industry means that most shippers are served by only one rail company. Railroads typically charge such “captive“ shippers 20 to 30 percent more than they do when another railroad is competing for the business. Shippers who feel they are being overcharged have the rig

34、ht to appeal to the federal governments Surface Transportation Board for rate relief, but the process is expensive, time consuming, and will work only in truly extreme cases. Railroads justify rate discrimination against captive shippers on the grounds that in the long nm it reduces everyones cost.

35、If railroads charged all customers the same average rate, they argue, shippers who have the option of switching to trucks or other forms of transportation would do so, leaving remaining customers to shoulder the cost of keeping up the line. It% theory to which many economists subscribe, but in pract

36、ice it often leaves railroads in the position of determining which companies will flourish and which will fail. “Do we really want railroads to be the arbiters of who wins and who loses in the marketplace?“ asks Martin Bercovici, a Washington lawyer who frequently represents shipper. Many captive sh

37、ippers also worry they will soon be his with a round of huge rate increases. The railroad industry as a whole, despite its brightening fortuning fortunes, still does not earn enough to cover the cost of the capital it must invest to keep up with its surging traffic. Yet railroads continue to borrow

38、billions to acquire one another, with Wall Street cheering them on. Consider the $10.2 billion bid by Norfolk Southern and CSX to acquire Conrail this year. Conrails net railway operating income in 1996 was just $427 million, less than half of the carrying costs of the transaction. Whos going to pay

39、 for the rest of the bill? Many captive shippers fear that they will, as Norfolk Southern and CSX increase their grip on the market. 21 According to those who support mergers railway monopoly is unlikely because _. （ A） cost reduction is based on competition. （ B） services call for cross-trade coord

40、ination. （ C） outside competitors will continue to exist. （ D） shippers will have the railway by the throat. 22 What is many captive shippers attitude towards the consolidation in the rail industry? （ A） Indifferent. （ B） Supportive. （ C） Indignant. （ D） Apprehensive. 23 It can be inferred from Para

41、graph 3 that _. （ A） shippers will be charged less without a rival railroad. （ B） there will soon be only one railroad company nationwide. （ C） overcharged shippers are unlikely to appeal for rate relief. （ D） a government board ensures fair play in railway business. 24 The word “arbiters“(Line 6, P

42、aragraph 4) most probably refers to those _. （ A） who work as coordinators. （ B） who function as judges. （ C） who supervise transact ions. （ D） who determine the price. 25 According to the text, the cost increase in the rail industry is mainly caused by_. （ A） the continuing acquisition. （ B） the gr

43、owing traffic. （ C） the cheering Wall Street. （ D） the shrinking market. 26 Americans today dont place a very high value on intellect. Our heroes are athletes, entertainers, and entrepreneurs, not scholars. Even our schools are where we send our children to get a practical education not to pursue kn

44、owledge for the sake of knowledge. Symptoms of pervasive anti-intellectualism in our schools arent difficult to find. “Schools have always been in a society where practical is more important than intellectual“, says education writer Diane Ravitch. “Schools could be a counterbalance“. Razitchs latest

45、 bock, Left Back: A Century of Failed School Reforms, traces the roots of anti-intellectualism in our schools, concluding they are anything but a counterbalance to the American distaste for intellectual pursuits. But they could and should be. Encouraging kids to reject the life of the mind leaves th

46、em vulnerable to exploitation and control. Without the ability to think critically, to defend their ideas and understand the ideas of others, they cannot fully participate in our democracy. Continuing along this path, says writer Earl Shortis, “We will become a second-rate country. We will have a le

47、ss civil society“. “Intellect is resented as a form of power or privilege“, writes historian and professor Richard Hofstadter in Anti-Intellectualism in American life, a Pulitzer Prize winning book on the roots of anti-intellectualism in US politics, religion, and education. From the beginning of ou

48、r history, says Hofstadter, our democratic and populist urges have driven us to reject anything that smells of elitism. Practicality, common sense, and native intelligence have been considered more noble qualities than anything you could learn from a book. Ralph Waldo Emerson and other Transcendenta

49、list philosophers thought schooling and rigorous book learning put unnatural restraints on children: “We are shut up in schools and college recitation rooms for 10 or 15 years and come out at last with a bellyful of words and do not know a thing“. Mark Twains Huckleberry Firm exemplified American anti-intellectualism. Its hero avoids being civilized going to school and learning to read so he can preserve his innate goodness. Intellect, according to Hofstadte
