The next one is at ten oclock.“Thats all right,“ they said, “Well go and have a drink.“ So off they went to a bar (酒吧间). A minute or two after ten oc
23、lock they came running and asked the guard, “Has the train gone?“Yes,“ the guard said. “It went at ten, as I told you. The next one is at eleven o clock.“Thats all right,“ they said again. “Well go and have another drink.“ So they went back to the bar.They missed the eleven o clock train in the same
24、 way. Then the guard said, “Now, the next train is the last one. If you miss that train, you wont get to London tonight.“Twelve oclock came, and the last train was just starting out when the three of them came out of the bar running as fast as they could. Two of them got in the train just as it was
25、leaving, but the third one didnt run fast enough, and the train went out leaving him behind. He stood there looking at the train and laughing, as if (好像) to miss a train was the best joke in the world. The guard went up to him and said, “I told you that this was the last train. Why didnt you come ea

29、re nine oclock, Dr Johnson was answering a telephone call. He was asked to go and give an operation to a very sick boy at once. The boy was in a small hospital in Glens Falls, sixty miles away from Dr Johnsons city-Albany. The boy had hurt himself in a traffic accident. His life was in danger, but h
30、is family was so poor that they could not pay the doctor anything. After he heard all this, Dr Johnson was driving carefully. He thought that he could get to the hospital before 12 oclock. A few minutes later, the doctors car had to stop for a red light at a crossing. Suddenly a man in an old black
31、coat opened the door of the car and got in.“Drive on“, he said. “Ive got a gun (枪).“Im a doctor,“ said Johnson. “Im on my way to a hospital to operate on a very sick.“Dont talk,“ said the man in the old black coat. “Just drive.“A mile out of the town he ordered the doctor to stop the car and get out
32、 Then the man drove on down the road. The doctor stood for a moment in the snow. A half hour, Dr Johnson found a telephone and called a taxi (出租车). At the railway (铁路) station he learned that the next train to Glens Falls would not leave until 12 oclock.It was after two oclock in the morning when t
33、he doctor arrived at the hospital in Glens Falls. Miss Clarke, a nurse, was waiting for him.“I did my best,“ said Dr Johnson. Miss Clarke said. “The boy died an hour ago.“They walked into the waiting room. There sat the man in the old black coat, with his head in his hands.“Mr Shute,“ said Miss Clar
34、ke to the man, “this is Dr Johnson. He had come all the way from Albany to try to save your boy./（分数：4.00）(1).From the story we know it took Dr Johnson _ to get to the hospital.（分数：1.00）A.12 hoursB.2 hoursC.only I hourD.about 5 hours(2).Dr Johnson was late because _.（分数：1.00）A.there was something wr
35、ong with his carB.a strange man made it hard to driveC.he picked up the strange manD.the train to Glens Falls was late(3).From the story we know Dr Johnson _.（分数：1.00）A.was a good man, he didnt care for the moneyB.hurt himself on the way to Glens FallsC.did the operation and the boy was savedD.wont
36、do the operation until the boys family paid the money(4).The man in an black coat _.（分数：1.00）A.hit the boy and ran awayB.took the boy to the hospitalC.was the boys fatherD.was the real doctorCAny physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove in
37、 No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory. On the other hand, you can disprove a theory by finding even a single observation that disagrees with the predictions of the theory. As ph
38、ilosopher of science Karl Popper has emphasized, a good theory is characterized by the fact that it makes a number of predictions that could in principle be disproved or falsified by observation. Each time new experiments are observed to agree with the predictions the theory survives, and our confid
39、ence in it is increased; but if ever a new observation is found to disagree, we have to abandon or modify the theory. At least that is what is supposed to happen, but you can always question the competence of the person who carried out the observation.In practice, what often happens is that a new th
40、eory is devised that is really an extension of the previous theory. For example, very accurate observations of the planet Mercury revealed a small difference between its motion and the predictions of Newtons theory of gravity. Einsteins general theory of relativity predicted a slightly different mot
41、ion from Newtons theory. The fact that Einsteins predictions matched what was seen, while Newtons did not, was one of the crucial confirmations of the new theory. However, we still use Newtons theory for all practical purposes because the difference between its predictions and those of general relat
42、ivity is very small in the situations that we normally deal with. (Newtons theory also has the great advantage that it is much simpler to work with than Einsteins!)（分数：4.00）(1).A good title for this passage is _.（分数：1.00）A.The History of Physical ScienceB.Karl Poppers Physical TheoryC.The Philosophy
43、 of ScienceD.Einsteins Theory of Science(2).Newtons theory of gravity was corrected by Einsteins theory because of _.（分数：1.00）A.a new hypothesis about gravityB.careful measurements of Mercurys motionC.new practical considerations of Newtons theoryD.newly predicted observations(3).A number of predict
44、ions can be disproved by _.A. observations C. experiments B. theories D. hypotheses（分数：1.00）A.B.C.D.(4).Which statement is true?（分数：1.00）A.Einsteins general theory of relativity will survive any observations to be found.B.The general theory of relativity is not an extention of the theory of gravity.
45、C.The general theory of relativity may be disproved or falsified.D.The general theory of relativity has completely replaced the theory of gravity.DIf it were only necessary to decide whether to teach elementary science to everyone on a mass basis or to find the gifted few and take them as far as the
46、y can go, our task would be fairly simple. The public school system, however, has no such choice, for the two jobs must be carried on at the same time. Because we depend so heavily upon science and technology for our progress, we must produce specialists in many fields. Because we live in a democrat
47、ic nation, whose citizens make the policies for the nation, large numbers of us must be educated to understand, to support, and when necessary, to judge the work of experts. The public school must educate both producers and users of scientific services.In education there should be a good balance amo
48、ng the branches of knowledge that contribute to effective thinking and wise judgement. Such balance is defeated by too much emphasis on any one field. This question of balance involves not only the relation of the natural sciences, the social sciences, and the arts but also relative emphasis among t
49、he natural sciences themselves. Similarly, we must have a balance between the current and classical knowledge. The attention of the public is continually drawn to new possibilities in scientific fields and the discovery of new knowledge; these should not be allowed to turn our attention away from the sound, established materials that form the basis of courses for beginners.（分数：4.00）(1).According to
