13、D.trifling二、Part Reading Compr(总题数：5，分数：19.50)It happened in the late fall of 1939 when, after a Nazi submarine had penetrated the British sea defense around the Firth of Forth and damaged a British cruiser, Reston and a colleague contrived to get the news past British censorship. They cabled a seri
14、es of seemingly harmless sentences to The Times“s editors in New York, having first sent a message instructing the editors to regard only the last word of each sentence. Thus they were able to convey enough words to spell out the story. The fact that the news of the submarine attack was printed in N
15、ew York before it had appeared in the British press sparked a big controversy that led to an investigation by Scotland Yard and British Military Intelligence. But it took the investigators eight weeks to decipher The Times“s reporters“ code, an embarrassingly slow bit of detective work, and when it
16、was finally solved the incident had given the story very prominent play, later expressed dismay that the reporters had risked so much for so little. And the incident left Reston deeply distressed. It was so out of character for him to have. become involved in such a thing. The tactics were questiona
17、ble and, though the United States was not yet in the war, Britain was already established as America“s close ally and breaking British censorship seemed both an irresponsible and unpatriotic thing to do.（分数：8.00）(1).The episode recounted in the passage took place _.（分数：2.00）A.just prior to the outbr
18、eak of the Second World WarB.bofore Britain entered the Second World WarC.before the United States entered the Second World WarD.while the United States was in the Second World War(2).It was clear that British censorship rules had been broken because the story was _.（分数：2.00）A.first published in New
19、 YorkB.published nowhere but in The TimesC.uncomplimentary to the BristishD.much fuller in its Times version than elsewhere(3).According to the author, the British did little about the story“s publication mainly because _.（分数：2.00）A.everyone responsible had apologized for what had happenedB.it took
20、the authorities too long to figure out how the censors had been outwittedC.Scotland Yard and British Military Intelligence disagreed about who was at faultD.they were afraid to admit that the censors had been so easily fooled(4).The passage indicates that eventually everyone involved came to regard
21、the publication of the story in The Times as a _.（分数：2.00）A.regrettable errorB.cheap journalistic trickC.brilliant journalistic maneuverD.proper exercise of the freedom of the pressBefore a big exam, a sound night“s sleep will do you more good than poring over textbooks. That, at least, is the folk
22、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 form. The other says that they are actually formed during
23、 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 Liege University in Belgium has managed to do it. The
24、 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 if watching a movie, and brainwave traces resemble those of wakefulness
25、. It is during this period of deep 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 slept during the following night. The task required them t
26、o 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 pattern-what is referred to as “artificial grammar“. Yet t
27、he 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 active brains. The “editing“ theory would not predict tha
28、t, 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 went to sleep. The team, therefore, concluded that the
29、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 soundly in the knowledge that what they will remember the
30、 next day are the basic rules of algebra and not the incoherent talk from the radio next door.（分数：0.00）(1).Researchers in behavioral psychology are divided with regard to _A.how dreams are modified in their coursesB.the difference between sleep and wakefulnessC.why sleep is of great benefit to memor
31、yD.the functions of a good night“s sleep(2).As manifested in the experimental study, rapid eye movement is characterized by _A.intensely active brainwave tracesB.subjects“ quicker response timesC.complicated memory patternsD.revival of events in the previous day(3).By referring to the artificial gra
32、mmar, the author intends to show _A.its significance in the studyB.an inherent pattern being learntC.its resemblance to the lightsD.the importance of night“s sleep21.A young man sees a sunset and unable to understand or express the emotion that it _ in him, concludes that it must be the gateway to a
33、 world that lies beyond.（分数：1.00）A.reflectsB.retainsC.rousesD.radiatesin science the meaning of the word “explain“ suffers with civilization“s every step in search of reality. Science cannot really explain electricity, magnetism, and gravitation; their effects can be measured and predicted, but of t
34、heir nature no more is known to the modem scientist than to Thales who first speculated on the electrification of amber. Most contemporary physicists reject the notion that man can ever discover what these mysterious forces “really“ are. “Electricity,“ Bertrand Russell says, “is not a thing, like St
35、. Paul“s Cathedral; it is a way in which things behave. When we have told how things behave when they are electrified, and under what circumstances they are electrified, we have told all there is to tell.“ Until recently scientists would have disapproved of such an idea. Aristotle, for example, whos
36、e natural science dominated Western thought for two thousand years, believed that man could arrive at an understanding of reality by reasoning from self-evident principles. He felt, for example, that it is a self-evident principle that everything in the universe has its proper place, hence one can d
37、educe that objects fall to the ground because that“s where they belong, and smoke goes up because that“s where it belongs. The goal of Aristotelian science was to explain why things happen. Modem science was born when Galileo began trying to explain how things happen and thus originated the method o
38、f controlled experiment which now forms the basis of scientific investigation.（分数：3.00）(1).Bertrand Russell“s notion about electricity is_（分数：1.00）A.disapproved of by most modern scientistsB.in agreement with Aristotle“s theory of self-evident principlesC.in agreement with scientific investigation d
39、irected toward “how“ things happenD.in agreement with scientific investigation directed toward “why“ things happen(2).The passage says that until recently scientists disagreed with the idea that_（分数：1.00）A.there are self-evident principlesB.there are mysterious forces in the universeC.man cannot dis
40、cover what forces “really“ areD.we can discover why things behave as they do(3).The expression “speculated on“ (Line 4) means_（分数：1.00）A.consideredB.suspectedC.expectedD.engaged in buying and sellingThe domestic economy in the United States expanded in a remarkably vigorous and steady fashion. The r
41、evival in consumer confidence was reflected in the higher proportion of incomes spent for goods and services and the marked increase in consumer willingness to take on installment debt. A parallel strengthening in business psychology was manifested in a stepped-up rate of plant and equipment spendin
42、g and a gradual pickup in expenses for inventory. Confidence in the economy was also reflected in the strength of the stock market and in the stability of the bond market. For the years as a whole, consumer and business sentiment benefited from the ease in East-West tensions. The bases of the busine
43、ss expansion were to be found mainly in the stimulative monetary and fiscal policies that had been pursued. Moreover, the restoration of sounder liquidity positions and tighter management control of production efficiency had also helped lay the groundwork for a strong expansion. In addition, the eco
44、nomic policy moves made by the President had served to renew optimism on the business outlook while boosting hopes that inflation would be brought under more effective control. Finaly, of course, the economy was able to grow as vigorously as it did because sufficient leeway existed in terms of idle
45、men and machines. The United States balance of payments deficit declined sharply. Nevertheless, by any other test, the deficit remained very large, and there was actually a substantial deterioration in our trade account to a sizable deficit, almost two-thirds of which was with Japan. While the overa
46、ll trade performance proved disappointing, there are still good reasons for expecting the delayed impact of devaluation to produce in time a significant strengthening in our trade picture. Given the size of the Japanese component of our trade deficit, however, the outcome will depend importantly on
47、the extent of the corrective measures undertaken by Japan. Also important will be our own efforts in the United States to fashion internal policies consistent with an improvement in our external balance. The underlying task of public policy for the year ahead-and indeed for the longer run-remained a
48、 familiar one: to strike the right balance between encouraging healthy economic growth and avoiding inflationary pressures. With the economy showing sustained and vigorous growth, and with the currency crisis highlighting the need to improve our competitive posture internationally, the emphasis seem
49、ed to be shifting to the problem of inflation. The Phase Three Program of wage and price restraint can contribute to reducing inflation. Unless productivity growth is unexpectedly large; however, the expansion of real output must eventually begin to slow down to the economy“s larger run growth potential if generalized demand pressures on prices are to be avoided.（分数：7.50）(1).The author mentions increased installment debt in the
