The doctor had almost lost hope at one point, but the patient finally______(苏醒过来).

Reading to oneself is a modern activity which was almost unknown to the scholars of the classical and medieval worlds while during the fifteenth century the term" reading" undoubtedly meant reading aloud. Only during the nineteenth century did silent reading become commonplace.One should be wary, however, of assuming that silent reading came about simply because reading aloud is a distraction to others. Examination of factors related to historical development of silent reading reveals that it became the usual mode of reading for most adult reading tasks mainly because the tasks themselves, changed in character.The last century saw a steady gradual increase in literacy, and thus in the number of readers. As readers increased, so the number of potential listeners declined, and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the flourishing of reading as a private activity in such public places as libraries, railway carriages and offices, where reading aloud would cause distraction to other readers.Towards the end of the century there was still considerable argument over whether books should be used for information or treated respectfully, and over whether the reading of material such as newspapers was in some way mentally weakening. Indeed this argument remains with Us still in education. However, whatever its virtues, the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by books and periodicals for a specialized readership on the other. By the end of the century students were being recommended to adopt attitudes to books and to use skills in reading them which were inappropriate, if not impossible, for the oral reader. The social, cultural, and technological changes in the century had greatly altered what the term "reading" implied. What is the writer of this passage attempting to do().

A. Explain how present- day reading habits developed.
B. Change people’s attitudes to reading.
C. Show how reading methods have improved.
D. Encourage the growth of reading.

The real reason why the author believes everything is farther than it used to be is that now it takes him twice as much time to walk from his home to the railway station.

Peter White: We’re facing a serious energy crisis. All known reserves of coal, oil and gas will be exhausted within ten years. It is imperative that we develop new sources of energy immediately. Nuclear power is the answer to our problems. If we don’t build nuclear power station now, our civilization will collapse. Bob Robin: We can’t allow this power station to be built. I’ll tell you why. It would cause terrible damage to the environment and all living creatures in the district would be in great danger. A small leak could cause a disaster. It is our duty as responsible citizens to force the government to abandon their nuclear energy program. Mark Brewer: This power station will be absolutely safe. They’ll be no danger of leakage because the reactor will be housed in a concrete box with wails six meters thick. Five independent alarm systems will monitor every square centimeter of the power station to prevent fire or sabotage. People are afraid of nuclear power because they don’t understand it. We must educate them. Nuclear power is clean, quiet, cheap and pollution-free, unlike conventional power using gas, oil and coal. Furthermore, it is almost unlimited. Harry Wells: I used to believe nuclear power stations were safe. But last month-1 saw a top-secret government report which revealed at least five major leaks in the last two years. In each case, the alarm systems afraid and there could have been a disaster. Scientists have too much faith in their own ideas and have helped the government to deceive the public. I think it’s time that the truth was told. Nuclear power stations are indeed very dangerous. Joe Forest: I think the government is placing too much emphasis on nuclear power. I mean, it’ll take many more years of experimentation before the safety problem alone is overcome. In the meantime, I think we should develop other ways of taking energy from the earth, such as sunshine, or the tide, waves, rivers, hot springs, etc. There are lots of alternative forms of energy. They are cheaper, safer and more convenient than nuclear power. Now match each of the persons to the appropriate statement. Note: There are two extra statements. Statements A. People have put nuclear energy to constructive uses, and also have put it to destructive uses. B. Other ways of taking energy should be developed until the safety problem associated with nuclear power is overcome. C. People should be educated to know that there’ll be no danger of leakage of nuclear power and that it is not like conventional power. D. Without nuclear power stations human society would stop functioning. E. Nuclear energy is safe when it is controlled and it can be made a useful form of energy. F. The government should tell the public the truth that nuclear power stations are indeed very dangerous. G. Nuclear power can cause terrible damage to the environment and put all living creatures in great danger. Harry Wells
