7、rt II Reading Comprehension (35 minutes)Directions:There are 4 reading 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 corresponding letter

8、on the Answer Sheet with a single line through the centre.Passage OneQuestions 21 to 25 are based on the following passage.The aim of the teacher is to get his pupils as quickly as possible over the period in which each printed symbol is looked at for its shape, and arrive at the stage when the pupi

9、l looks at words and phrases, for their meaning, almost without noticing the shapes of the separate letters.When a good reader is at work he does not look at letters, nor even at words, one by one, however, he quickly takes in the meaning of two, three, or four words at a time, in a single moment. W

10、atch carefully the eyes of a person who is reading, and it will be seen that they do not travel smoothly along the lines of print, but they move by jumps separated by very short stops. The eyes of a very good reader move quickly, taking long jumps and making very short halts (停顿); the eyes of a poor

11、 reader move more slowly, taking only short jumps and stopping longer at each halt. Sometimes, when he meets a difficulty, he even goes backwards to see again what has already been looked at once.The teachers task is therefore clear: it is to train his pupils to take in several words at a glance (on

12、e eye-jump) and to remove the necessity for going backwards to read something a second time.This shows at once that letter-by-letter, or syllable-by-syllable, or word-by-word reading, with the finger pointing to the word, carefully fixing each one in turn, is wrong. It is wrong because such a method

13、 ties the pupils eyes down to a very short jump, and the aim is to train for the long jump. Moreover, a very short jump is too short to provide any meaning or sense; and it will be found that having struggled with three or four words separately, the pupil has to look at them again, all together and

14、in one group, in order to get the meaning of the whole phrase.21.Which of the following is closest in meaning to the first paragraph?A) Pupils should be trained to reach quickly the stage of reading without having to concentrate on the separate symbols.B) Pupils should look at each printed symbol fo

15、r its meaning as well as for its shape.C) Teachers should help their pupils avoid looking at the shape of the printed symbols.D) Teachers should tell their pupils the different stages of their study.22.In a single moment, a good reader picks up _.A) several wordsB) several phrasesC) several sentence

16、sD) several lines23.Teachers encourage the use of dictionaries so that _.A) students will be able to express their ideas more freelyB) teachers will have less trouble in correcting mistakesC) students will have more confidence in writingD) students will learn to be independent of teachers24.The writ

17、er seems to think that the teachers judgement on that sensitive piece of writing is _.A) reasonableB) unfairC) foolishD) careless25.The major point discussed in the passage is _.A) the importance of developing writing skillsB) the complexities of spellingC) the correct way of marking compositionsD)

18、the relationship between spelling and the content of a compositionPassage TwoQuestions 26 to 30 are based on the following passage.A breakthrough (突破) in the provision of energy from the sun for the European Economic Community (EEC) could be brought forward by up to two decades, if a modest increase

19、 could be provided in the EECs research effort in this field, according to the senior EEC scientists engaged in experiments in solar energy at EECs scientific laboratories at Ispra, near Milan.The senior West German scientist in charge of the Communitys solar energy programme, Mr. Joachim Gretz, tol

20、d journalists that at present levels of research spending it was most unlikely that solar energy would provide as much as three per cent of the Communitys energy requirements even after the year 2000. But he said that with a modest increase in the present sums, devoted by the EEC to this work it was

21、 possible that the breakthrough could be achieved by the end of the next decade.Mr. Gretz calculates that if solar energy only provided three per cent of the EECs needs, this could still produce a saving of about a billion pounds in the present bill for imported energy each year. And he believes tha

22、t with the possibility of utilizing more advanced technology in this field it might be possible to satisfy a much bigger share of the Communitys future energy needs.At present the EEC spends about $2.6 millions a year on solar research at Ispra, one of the EECs official joint research centres, and a

23、nother $3 millions a year in indirect research with universities and other independent bodies.26.The phrase “be brought forward” (Line 2, Para. 1) most probably means _.A) be expectedB) be completedC) be advancedD) be introduced27.Some scientists believe that a breakthrough in the use of solar energ

24、y depends on _.A) sufficient fundingB) further experimentsC) advanced technologyD) well-equipped laboratories28.According to Mr. Gretz, the present sum of money will enable the scientists to provide _.A) more than 3 , 6 of the EECs needs after the year 2000B) only 3% of the EECs needs before the yea

25、r 2000C) less than 3% of the EECs needs before the year 2000D) 3% of the EECs needs after the year 200029.Which of the following is NOT true according to the passage?A) The EEC spends one billion pounds on imported energy each year.B) At the present level of research spending, it is difficult to mak

26、e any significant progress in the provision of energy from the sun.C) The desired breakthrough could be obtained by the end of the next decade if investment were increased.D) The total yearly spending of the EEC on solar energy research amounted to almost 6 million.30.The application of advanced tec

27、hnology to research in solar energy _.A) would lead to a big increase in research fundingB) would make it unnecessary to import oilC) would make it possible to meet the future energy needs of the EECD) would provide a much greater proportion of the Communitys future energy needsPassage ThreeQuestion

28、s 31 to 35 are based on the following passage.Just seven years ago, the Jarvik-7 artificial heart was being cheered as the model of human creativeness. The sight of Barney Clark-alive and conscious after trading his diseased heart for a metal-and-plastic pump-convinced the press, the public and many

29、 doctors that the future had arrived. It hadnt. After monitoring production of the Jarvik-7, and reviewing its effects on the 150 or so patients (most of whom got the device as a temporary measure) the U.S. Food and Drug Administration concluded that the machine was doing more to endanger lives than

30、 to save them. Last week the agency cancelled its earlier approval, effectively banning (禁止) the device.The recall may hurt Symbion Inc., maker of the Jarvik-7, but it wont end the request for an artificial heart. One problem with the banned model is that the tubes connecting it to an external power

31、 source created a passage for infection. Inventors are now working on new devices that would be fully placed, along with a tiny power pack, in the patients chest. The first sample products arent expected for another 10 or 20 years: But some people are already worrying that theyll work-and that Ameri

32、cas overextended health-care programs will lose a precious $2.5 billion to $5 billion a year providing them for a relatively few dying patients. If such expenditures (开支) cut into funding for more basic care, the net effect could actually be a decline in the nations health.31.According to the passag

The early trains were impractical curiosities, and for a long time the railroad companies met with troublesome mechanica

38、l problems. The most serious ones were the construction of rails able to bear the load, and the development of a safe, effective stopping system. Once these were solved, the railroad was established as the best means of land transportation. By 1860 there were thousands of miles of railroads crossing

39、 the eastern mountain ranges and reaching westward to the Mississippi. There were also regional southern and western lines.The high point in railroad building came with the construction of the first transcontinental system. In 1862 Congress authorized two western railroad companies to build lines fr

40、om Nebraska westward and from California eastward to a meeting point, so as to complete a transcontinental crossing linking the Atlantic seaboard with the Pacific. The Government helped the railroads generously with money and land. Actual work on this project began four years later. The Central Paci

41、fic Company, starting from California, used Chinese labor, while the Union Pacific employed crews of Irish laborers. The two groups worked at remarkable speed, each trying to cover a greater distance than the other. In 1869 they met at a place called Promontory in what is now the state of Utah. Many

42、 visitors came there for the great occasion. There were joyous celebrations all over the country, with parades and the ringing of church bells to honor the great achievement.The railroad was very important in encouraging westward movement.
