16、an poring over textbooks. That, at least, is the folk wisdom. And science, in the form of behavioral psychology, supports that wisdom. But such behavioral studies cannot distinguish between two competing theories of why sleep is good for the memory. One says that sleep is when permanent memories for

17、m. The other says that they are actually formed during the day, but then “edited at night, to flush away what is superfluous. To tell the difference, it is necessary to look into the brain of a sleeping person, and that is hard. But after a decade of painstaking work, a team led by Pierre Maquet at

18、Liege University in Belgium has managed to do it. The particular stage of sleep in which the Belgian group is interested in is rapid eye movement (REM) sleep, when brain and body are active, heart rate and blood pressure increase, the eyes move back and forth behind the eyelids as ff watching a movi

19、e, and brainwave traces resemble those of wakefulness. It is during this period of sleep that people are most likely to relive events of the previous day in dreams. Dr. Maquet used an electronic device called PET to study the brains of people as they practiced a task during the day, and as they slep

20、t during the following night. The task required them to press a button as fast as possible, in response to a light coming on in one of six positions. As they learnt how to do this, their response times got faster. What they did not know was that the appearance of the lights sometimes followed a patt

21、ern-what is referred to as “artificial grammar“. Yet the reductions in response time showed that they learnt faster when the pattern was present than when there was not. What is more, those with more to learn (i. e., the “grammar“, as well as the mechanical task of pushing the button) have more acti

22、ve brains. The “editing“ theory would not predict that, since the number of irrelevant stimuli would be the same in each case. And to eliminate any doubts that the experimental subjects were learning as opposed to unlearning, their response times when they woke up were even quicker than when they we

23、nt to sleep. The team, therefore, concluded that the nerve connections involved in memory are reinforced through reactivation during REM sleep, particularly if the brain detects an inherent structure in the material being learnt. So now, on the eve of that crucial test, maths students can sleep soun

24、dly in the knowledge that what they will remember the next day are the basic rules of algebra and not the incoherent talk from the radio next door. 21 Researchers in behavioral psychology are divided with regard to _ . （ A） how dreams are modified in their courses （ B） the difference between sleep a

25、nd wakefulness （ C） why sleep is of great benefit to memory （ D） the functions of a good nights sleep 22 As manifested in the experimental study, rapid eye movement is characterized by _ . （ A） intensely active brainwave traces （ B） subjects quicker response times （ C） complicated memory patterns （

26、D） revival of events in the previous day 23 By referring to the artificial grammar, the author intends to show _ . （ A） its significance in the study （ B） an inherent pattern being learnt （ C） its resemblance to the lights （ D） the importance of nights sleep 24 In their study, researchers led by Pie

27、rre Maquet took advantage of the technique of _ . （ A） exposing a long-held folk wisdom （ B） clarifying the predictions on dreams （ C） making contrasts and comparisons （ D） correlating effects with their causes 25 What advice might Maquet give to those who have a crucial test the next day? （ A） Memo

28、rizing grammar with great efforts. （ B） Study textbooks with close attention. （ C） Have their brain images recorded. （ D） Enjoy their sleep at night soundly. 25 The Food and Drug Administration said Wednesday that it is trying to track down as many as 386 piglets that may have been genetically engin

29、eered and wrongfully sold into the U.S. food supply. The focus of the FDA investigation is pigs raised by researchers at the University of Illinois in Urbana Champaign. They engineered the animals with two genes: One is a cow gene that increases milk production in the sow. The other, a synthetic gen

30、e, makes the milk easier for piglets to digest. The goal was to raise bigger pigs faster. There has been no evidence that either genetically altered plants or animals actually trigger human illness, but critics warn that potential side effects remain unknown. University officials say their tests sho

31、wed the piglets were not born with the altered genes, but FDA rules require even the offspring of genetically engineered animals to be destroyed so they don t get into the food supply. The FDA, in a quickly arranged news conference Wednesday prompted by inquiries by USA TODAY, said the University of

32、 Illinois will face possible sanctions and fines for selling the piglets to a livestock broker, who in turn sells to processing plants. Both the FDA and the university say the pigs that entered the market do not pose a risk to consumers. But the investigation follows action by the U.S. Department of

33、 Agriculture in December to fine a Texas company that contaminated 500,000 bushels of soybeans with com that had been genetically altered to produce a vaccine for pigs. Critics see such cases as evidence of the need for more government oversight of a burgeoning area of scientific research. “This is

34、a small incident, but its incident like this that could destroy consumer confidence and export confidence,“ says Stephanie Childs of the Grocery Manufacturers of America. “We already have Europe shaky on biotech. The countries to whom we export are going to look at this.“ The University of Illinois

35、says it tested the DNA of every piglet eight times to make sure that the animal hadnt inherited the genetic engineering of its mother. Those piglets that did were put back into the study. Those that didn t were sold to the pig broker. “Any pig who s tested negative for the genes since 1999 has been

36、sent off to market,“ says Charles Zukoski, vice chancellor for research. But FDA deputy commissioner Lester Crawford says that under the terms of the universitys agreement with the FDA, the researchers were forbidden to remove the piglets without FDA approval. “The University of Illinois failed to c

37、heck with FDA to see whether or not the animals could be sold on the open market. And they were not to he used under any circumstance for food.“ The FDA is responsible for regulating and overseeing transgenic animals because such genetic manipulation is considered an unapproved animal drug. 26 The 3

38、86 piglets wrongfully sold into food supply are from _ . （ A） Europe （ B） an American research organization （ C） a meat processing plant （ D） an animal farm 27 The purpose of the transgenic engineering research is to _ . （ A） get pigs of larger size in a shorter time （ B） make sows produce more milk

39、 （ C） make cows produce more milk （ D） make pigs grow more lean meat 28 The 4th paragraph shows that the University of Illinois _ . （ A） was criticized by the FDA （ B） is in great trouble （ C） IS required by the FDA to call back the sold piglets （ D） may have to pay the penalty 29 The FDA declares t

40、hat the wrongfully sold piglets _ . （ A） may have side effects on consumers （ B） may be harmful to consumers （ C） are safe to consumers （ D） may cause human illness 30 It can be inferred from this passage that _ . （ A） all the offspring have their mothers genetic engineering （ B） part of the offspri

41、ng have their mothers genetic engineering （ C） none of the offspring have their mothers genetic engineering （ D） half of the offspring have their mothers genetic engineering 30 The study of philosophies should make our own ideas flexible. We are all of us apt to take certain general ideas for grante

42、d, and call them common sense. We should learn that other people have held quite different ideas, and that our own have started as very original guesses of philosophers. A scientist is apt to think that all the problems of philosophy will ultimately be solved by science. I think this is true for a g

43、reat many of the questions on which philosophers still argue. For example, Plato thought that when we saw something, one ray of light came to it from the sun, and another from our eyes and that seeing was something like feeling with a stick. We now know that the light comes from the sun, and is refl

44、ected into our eyes. We don t know in much detail how the changes in our eyes give rise to sensation. But there is every reason to think that as we learn more about the physiology of the brain, we shall do so, and that the great philosophical problems about knowledge are going to be pretty fully cle

45、ared up. But if our descendants know the answers to these questions and others that perplex ns today, there will still be one field of which they do not know, namely the future. However exact our science, we cannot know it ns we know the past. Philosophy may be described as argument about things of

46、which we are ignorant. And where science gives us a hope of knowledge it is often reasonable to suspend judgment. That is one reason why Marx and Engels quite rightly wrote to many philosophical problems that interested their contemporaries. But we have got to prepare for the future, and we cannot d

47、o so rationally without some philosophy. Some people say we have only got to do the duties revealed in the past and laid down by religion, and god will look after the future. Other say that the world is a machine and the course of future events is certain, whatever efforts we may make. Marxists say

48、that the future depends on ourselves, even though we are part of the historical process. This philosophical view certainly does inspire people to very great achievements. Whether it is true or not, it is powerful guide to action. We need a philosophy, then, to help us to tackle the future. Agnostici

49、sm easily becomes an excuse for laziness and conservatism. Whether we adopt Marxism or any other philosophy, we cannot understand it with-out knowing something of how it developed. That is why knowledge of the history of philosophy is important to Marxists, even during the present critical days. 31 What is the main idea of this passage? （ A） The argument whether philosophy will ul
