27、59 “I cant go any farther,“John Smith thought. “I must get a rest before I go on. Theyll look for me first up there on the mountain where the plane was shot down. Theyre sure to find the chute(降落伞 )in the end. So theyll know Im not dead. Theyll think Im hiding up there in the trees and so theyll loo

28、k for me there. So Ill go down to the village as soon as possible. With luck by the evening my aching foot will be good enough to get me to the border. “ Far above him on the mountainside he could hear someone whispering which frightened him a lot after the great silence. Looking up he saw some ligh

29、ts moving across the face of the mountain in the grey light. But there was nobody on the head for the moment, and he dragged himself along towards the village, still almost invisible in the first light. At last he reached the church. How he wished to go in, but he knew that he would not do. Instead,

30、 he struggled along its walls towards a very old building not far away from the church doors. John Smith pushed open the heavy wooden door and slipped inside! 60 John Smith had to rest because_. （ A） he had been walking down the mountain too fast （ B） his bag had been so heavy to carry （ C） he hadnt

33、who had landed in an enemy country. （ D） A spy who had been hiding in the forest. 63 Any physical theory is always provisional, in the sense that it is only a hypothesis; you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that th

34、e 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 philosopher of science Karl Popper has emphasized, a good theory is characterized by the fact that it makes a

35、 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 confidence is increased; but if ever a new observation is found to disagree we have to abandon or modify the theo

36、ry. At least that is when 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 theory is devised that is really an extension of the previous theory. Fox example, very accurate observations of th

37、e 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 motion from Newtons theory. The fact that Einsteins predictions matched what was seen, while Newtons did not, was on

38、e 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 relativity is very small in the situations that we normally deal with. (Newtons theory also has the great advantage th

39、at it is much simpler to work with than Einsteins!) 64 A good title for this passage is_. （ A） The History of Physical Science （ B） Karl Poppers Physical Theory （ C） The Philosophy of Science （ D） Einsteins Theory of Science 65 Newtons theory of gravity was corrected by Einsteins theory because of_.

40、 （ A） a new hypothesis about gravity （ B） careful measurements of Mercurys motion （ C） new practical considerations of Newtons theory （ D） newly predicted observations 66 A number of predictions can be disproved by_. （ A） observations （ B） experiments （ C） theories （ D） hypotheses 67 Which statement

41、 is true? （ A） Einsteins general theory of relativity will survive any observations to be found. （ B） The general theory of relativity is not an extension of the theory of gravity. （ C） The general theory of relativity may be disproved or falsified. （ D） The general theory of relativity has complete

42、ly replaced the theory of gravity. 67 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 doctors

43、 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 to save t

44、hem 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 source cr

45、eated a passage for infection(感染 ). 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 Americas o

46、verextended health-care programs will lose a precious $ 5 billion a year providing them for a relatively few dying patients.
