　　One place where children soak up A characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools adopt the "win at all costs" moral standard and measure their success by sporting achievements. The current passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B-type fellows. Being too keen to win can have dangerous consequences: remember that Pheidippides, the first marathon runner, dropped dead seconds after saying: "Rejoice, we conquer!".

　　Judging from recent surveys,most experts in sleep behavior agree that there is virtually an epidemic ***流行病*** of sleepiness in the nation. “I can'tthink of a single study that hasn't found Americans getting less sleep thanthey ought to,” says Dr. David. Even people who think they are sleeping enoughwould probably be better off with more rest.

　　The beginning of our sleep-deficit ***睡眠不足*** crisis can betraced to the invention of the light bulb a century ago. From diary entries andother personal accounts from the 18th and 19th centuries, sleep scientists havereached the conclusion that the average person used to sleep about 9.5 hours anight. “The best sleep habits once were forced on us, when we had nothing to doin the evening down on the farm, and it was dark.” By the 1950s and 1960s, thatsleep schedule had been reduced dramatically, to between 7.5 and eight hours,and most people had to wake to an alarm clock. “People cheat on their sleep,and they don't even realize they're doing it,” says Dr. David. "They thinkthey're okay because they can get by on 6.5hours, when they really need 7.5, eight or even more to feel ideallyvigorous."

　　Perhaps the most merciless robber of sleep,researchers say, is the complexity of the day. Whenever pressures from work,family, friends and community mount, many people consider sleep the leastexpensive item on his programme. 'In our society, you're considered dynamic ifyou say you only need 5.5 hours' sleep. If you've got to get 8.5 hours, peoplethink you lack drive and ambition."

　　To determine the consequences of sleep deficit,researchers have put subjects through a set of psychological and performancetests requiring them, for instance, to add columns of numbers or recall apassage read to them only minutes earlier. "We've found that if you're insleep deficit, performance suffers," says Dr. David. “Short-term memory isweakened, as are abilities to make decisions and to concentrate.”

　　1.B答案見第2段第1句。18、19世紀的時候，首先是因為沒有電燈照明，所以人們晚上才無事可做，只好早早睡覺。而不是D項所說，是由於無事可做才多睡。

　　2.B全篇多處提到Dr.David的看法，在文中找到有Dr.David說話的地方，綜合比較一下，不難看出Dr.David認為美國人經常忽視睡眠不足的後果。

　　3.A答案見第2段倒數第1、2句和第3段第1、2句。

　　4.C最後一段一開始就講，為了確定睡眠不足所產生的後果，研究人員讓subjects通過一系列心理和行為的測試，要求他們把一欄數字相加或者回憶剛讀過的文章。這樣看來，subjects應該是指人了。

　　5.D推理題，依據見本文最後兩句話。其實，也只有D項才把睡眠充足所帶來的好處講得最完整。
