根据下列材料，请回答下列各题 We all know that the normal human daily cycle of activity is

of some 7-8 hours sleep alternating with some16-17 hours wakefulness and that, broadly speaking, the sleep normally coincides with the hours of darkness. Ourpresent concern is with how easily and to what extent this cycle can be modified. The question is no mere academic one. The ease, for example, with which people can change from working inthe day to working at night is a question of growing importance in industry where automation calls for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed routine ofsleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industrythat shifts are changed every week; a person may work from 12 midnight to 8 a.m. one week, 8 a.m. to 4 p.m. the next, and 4 p.m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has tochange to another, so that much of his time is spent neither working nor sleeping very efficiently. One answer would seem to be longer periods on each shift, a month, or even three months. Recent research byBonjer of the Netherlands, however, has shown that people on such systems will revert to their normal habits ofsleep and wakefulness during the weekend and that this is quite enough to destroy any adaptation to night workbuilt up during the week. The only real solution appears to be to hand over the night shift to a number of permanent night workers. Aninteresting study of the domestic life and health of night-shift workers was carried out by Brown in 1957. Shefound a high incidence of disturbed sleep and other disorders among those on alternating day and night shifts, butno abnormal occurrence of these phenomena among those on permanent night work. This latter system then appears to be the best long-term policy, but meanwhile something may be done torelieve the strains of alternate day and night work by selecting those people who can adapt most quickly to thechanges of routine. One way of knowing when a person has adapted is by measuring his body temperature. Peopleengaged in normal day-time work will have a high temperature during the hours of wakefulness and a low one atnight; when they change to night work the pattern will only gradually go back to match the new routine and thespeed with which it does so parallels, broadly speaking, the adaptation of the body as a whole, particularly in termsof performance. Therefore, by taking body temperature at intervals of two hours throughout the period ofwakefulness it can be seen how quickly a person can adapt to a reversed routine, and this could be used as a basisfor selection. So far, however, such a form. of selection does not seem to have been applied in practice. The study of sleep cycle can be of practical use to places where________

A. strict work shifts are required to cater for the need of automatic machines

B. working at night is normal for most employees

C. employees work according to different requirements of machines

D. employees have to adapt to irregular work patterns and organizations

根据下列短文，回答下列各题。 In the college-admissions wars, we parents are the true fight

ers. Were pushing our kids to get good grades, take SAT preparatory courses and build resunes so they can get into the college of our first choice. Fee twice been to the wars, and as I survey the battlefield, something different is happening. We see our kids college background as a prize demonstrating how well weve raised them. But we cant acknowledge that our obsession (痴迷) is more about us than them. So weve contrived various justifications that turn out to be half-truths, prejudices or myths. It actually doesnt matter much whether Aaron and Nicole go to Stanford. We have a full-blown prestige panic; we worry that there wont be enough prizes to go around. Fearful parents urge their children to apply to more schools than ever. Underlying the hysteria (歇斯底里) is the belief that scarce elite degrees must be highly valuable. Their graduates must enjoy more success because they get a better education and develop better contacts. All that is plausible-and mostly wrong. We havent found any convincing evidence that selectivity or prestige matters. Selective schools dont systematically employ better instructional approaches than less selective schools. On two measures---professors feedback and the number of essay exams---selective schools do slightly worse. By some studies, "selective schools do enhance their graduates lifetime earnings. The gain is reckoned at 2-4% for every 100-point increase in a schools average SAT scores. But even this advantage is probably a statistical fluke (偶然). A well-known study examined students who got into highly selective schools and then went elsewhere. They earned just as much as graduates from higher-status schools. Kids count more than their colleges. Getting into Yale may signify intelligence, talent and ambition. But its not the only indicator and, paradoxically, its significance is declining. The reason: so many similar people go elsewhere. Getting into college isnt lifes only competition. In the next competition---the job market and graduate school--the results may change. Old-boy networks are breaking down. Princeton economist Alan Krueger studied admissions to one top Ph.D. program. High scores on the GRE helped explain who got in; degrees of prestigious universities didnt. So, parents, lighten up. The stakes have been vastly exaggerated. Up to a point, we can rationalize our pushiness. America is a competitive society; our kids need to adjust to that. But too much pushiness can be destructive. The very ambition we impose on our children may get some into Harvard but may also set them up for disappointment. One study found that, other things being equal, graduates of highly selective schools experienced more job dissatisfaction. They may have been so conditioned to being on top that anything less disappoints. Why does the author say that parents are the true fighters in the college-admissions wars？

A.They have the final say in which university their children are to attend.

B.They know best which universities are most suitable for their children.

C.They have to carry out intensive surveys of colleges before children make an application.

D.They care more about which college their children go to than the children themselves.

根据下列短文，回答下列各题。 Imagine waking up and finding the value of your assets has

been halved. No, youre not an investor in one of those hedge funds that failed completely. With the dollar slumping to a 26-year low against the pound, already- expensive London has become quite unaffordable. A coffee at Starbucks, just as unavoidable in England as it is in the United States, runs about $8. The once all-powerful dollar isnt doing a Titanic against just the pound. It is sitting at a record low against the euro and at a 30-year low against the Canadian dollar. Even the Argentine peso and Brazilian real are thriving against the dollar. The weak dollar is a source of humiliation (屈辱), for a nations self-esteem rests in part on the strength of its currency. Its also a potential economic problem, since a declining dollar makes imported food more expensive and exerts upward pressure on interest rates. And yet there are substantial sectors of the vast U.S. economy--from giant companies like Coca-Cola to morn-and-pop restaurant operators in Miami--for which the weak dollar is most excellent news. Many Europeans may view the U.S. as an arrogant superpower that has become hostile to foreigners. But nothing makes people think more warmly of the U.S. than a weak dollar. Through April, the total number of visitors from abroad was up 6.8 percent from last year. Should the trend continue, the number of tourists this year will finally top the 2000 peak. Many Europeans now apparently view the U.S. the way many Americans view Mexico--as a cheap place to vacation, shop and party, all while ignoring the fact that the poorer locals cant afford to join the merrymaking. The money tourists spend helps decrease our chronic trade deficit. So do exports, which, thanks in part to the weak dollar, soared 11 percent between May 2006 and May 2007. For the first five months of 2007, the trade deficit actually fell 7 percent from 2006. If you own shares in large American corporations, youre a winner in the weak-dollsr gamble. Last week Coca-Colas stock bubbled to a five-year high after it reported a fantastic quarter. Foreign sales accounted for 65 percent of Cokes beverage (饮料) business. Other American companies profiting from this trend include McDonalds and IBM. American tourists, however, shouldnt expect any relief soon. The dollar lost strength the way many marriages break up--slowly, and then all at once. And currencies dont turn on a dime. So if you want to avoid the pain inflicted by the increasingly pathetic dollar, cancel that summer vacation to England and look to New England. There, the dollar is still treated with a little respect. Why do Americans feel humiliated？

A.Their economy is plunging.

B.Their currency has slumped.

C.They cant afford trips to Europe.

D.They have lost half of their assets.
