 Passage Three

  Questions 31 to 35 are based on the following passage:

  For about three centuries we have been doing science, trying science out, using science for the construction of what we call modern civilization. Every dispensable item of contemporary technology, from canal locks to dial telephones to penicillin, was pieced together from the analysis of data provided by one or another series of scientific experiments. Three hundred years seems a long time for testing a new approach to human interliving, long enough to settle back for critical appraisal of the scientific method, maybe even long enough to vote on whether to go on with it or not. There is an argument.

  Voices have been raised in protest since the beginning, rising in pitch and violence in the nineteenth century during the early stages of the industrial revolution, summoning urgent crowds into the streets any day these days on the issue of nuclear energy. Give it back, say some of the voices, it doesn't really work, we've tried it and it doesn't work, go back three hundred years and start again on something else less chancy for the race of man.

  The principle discoveries in this century, taking all in all, are the glimpses of the depth of our ignorance about nature. Things that used to seem clear and rational, matters of absolute certainty-Newtonian mechanics, for example-have slipped through our fingers, and we are left with a new set of gigantic puzzles, cosmic uncertainties, ambiguities; some of the laws of physics are amended every few years, some are canceled outright, some undergo revised versions of legislative intent as if they were acts of Congress.

  Just thirty years ago we call it a biological revolution when the fantastic geometry of the DNA molecule was exposed to public view and the linear language of genetics was decoded. For a while, things seemed simple and clear, the cell was a neat little machine, a mechanical device ready for taking to pieces and reassembling, like a tiny watch. But just in the last few years it has become almost unbelievably complex, filled with strange parts whose functions are beyond today's imagining.

  It is not just that there is more to do, there is everything to do. What lies ahead, or what can lie ahead if the efforts in basic research are continued, is much more than the conquest of human disease or the improvement of agricultural technology or the cultivation of nutrients in the sea. As we learn more about fundamental processes of living things in general we will learn more about ourselves.

  31.What can' t be inferred from the 1st paragraph?

  A) Scientific experiments in the past three hundred years have produced many valuable items.

  B) For three hundred years there have been people holding hostile attitude toward science.

  C) Modern civilization depends on science so man supports scientific progress unanimously.

  A) man has overthrown Newton' s laws of physics

  B) man has solved a new set of gigantic puzzles

  C) man has lost many scientific discoveries

  D) man has given up some of the once accepted theories

  33.Now scientists have found in the past few years.

  A) the exposure of DNA to the public is unnecessary

  B) the tiny cell in DNA is a neat little machine

  C) man knows nothing about DNA

  D) man has much to learn about DNA

  34.The writer's main purpose in writing the passage is to say that .

  A) science is just at its beginning

  B) science has greatly improved man's life

  C) science has made profound progress

  D) science has done too little to human beings

  Passage Four

  Questions 36 to 40 are based on the following passage:

  Efforts to educate people about the risks of substance abuse(毒品滥用)seem to deter some people from using dangerous substances, if such efforts are realistic about what is genuinely dangerous and what is not. Observed declines in the use of such drugs as LSD, PCP, and quaaludes since the early 1970s are probably related to increased awareness of the risks of their use, and some of this awareness was the result of warnings about these drugs in “ underground ”papers read by drug users. Such sources are influential, because they do not give a simple “all drugs are terrible for you” message. Drug users know there are big variations in danger among drugs, and antidrug education that ignores or denies this is likely to be ridiculed. This is illustrated by the popularity among young marijuana users of Reefer Madness, a widely unrealistic propaganda film against marijuana made in the 1930s. This film made the rounds of college campuses in the 1970s and joined rock music videos on cable television's MTV in the 1980s. Instead of deterring marijuana use, it became a cult(风靡一时的)film among users, many of whom got high to watch it.

  Although persuasion can work for some people if it is balanced and reasonable, other people seem immune to the most reasoned educational efforts. Millions have started smoking even though the considerable health risks of smoking have been well known and publicized for years. Moreover, the usefulness of education lies in primary prevention: prevention of abuse among those who presently have no problem. Hence, Bomier's contention that “if the Pepsi generation can be persuaded to drink pop wine, they can be persuaded not to drink it while driving” is probably not correct, since most drunken driving is done by people who already have significant drinking problems, and hence seem not to be dissuaded even by much stronger measures such as loss of a driver's license.

  36.According to the passage, up to now, antidrug education.

  A) has made all people see the danger of drugs

  B) has succeeded in dissuading people from using drugs

  C) has been effective only to a certain degree

  D) has proved to be a total failure

  37.The film “Reefer Madness” mentioned in the passage.

  A) effectively deterred marijuana use

  B) was rejected by young marijuana users

  C) did not picture the danger of marijuana realistically

  D) was welcomed by marijuana users because it told them how to get high

  38.The message “all drugs are terrible for you” is not influential because.

  A) it ignores the fact that drugs vary greatly in danger

  B) it gives a false account of the risks of drug use

  C) some drugs are good for health

  D) it does not appear in underground papers

  39.According to the passage, which of the following statements is NOT true?

  A) Even balanced and reasonable antidrug persuasion is influential only to some people.

  B) Most drug users are ignorant of the danger of drugs.

  C) Punishments such as loss of a driver's license do not seem to be an effective way to stop drunken driving.

  D) Primary prevention is a useful principle to be followed in antidrug education.

  40.The best title for the passage would be .

  A) Are All Drugs Terrible for You?

  B) Do People Believe What Underground Papers Say?

  C) Is There an Increased Awareness of the Risks of Drugs?

  D) Can Persuasion Reduce Drug Abuse?
