阅读理解 Judging from recent surveys,most experts in sleep behaviour agree that there is virtually an epidemic (流行病) of sleepiness in the nation."I can't think of a single study that hasn't found Americans getting less sleep than they ought to," says Dr David.Even people who think they are sleeping enough would probably be better off with more rest. The beginning of our sleepdeficit crisis can be traced back to the invention of the light bulb a century ago.From diary entries and our personal accounts from the 18th and 19th centuries,sleep scientists have reached the conclusion that the average person ud to sleep about 9.5 hours a night."The best sleep habitsonce were forced on us,when we had nothing to do in the evening down on the farm,and it was dark." Bythe 1950s and 1960s,the sleep schedule had been reduced dramatically,to between 7.5 and 8 hours,and most people had to wake to an alarm clock."People cheat in their sleep,and they don't even realize they'redoing it," says Dr David."They think they're okay becau they can get by on 6.5 hours,when they really need 7.5,8 or even more to feel ideally energetic." Perhaps the most merciless robber of sleep,rearches say,is the complexity of the day.Whenever pressures from work , family, friends and community increa , many people consider sleep the leastexpensive item on their programme."In our society,you're considered dynamic if you say you need only 5.5 hours' sleep.If you've got to get 8.5 hours,people think you lack drive and ambition." To determine the conquences of sleepdeficit , rearchers have put subjects through a t of psychological and performance tests requiring them,for instance,to add columns of numbers or recall a passage read to them only minutes earlier."We've found that if you're in sleepdeficit,performance suffers," says Dr David."Shortterm memory is weakened,as are abilities to make decisions and to concentrate."1.What is the main topic of the passage?A.Rearch on the caus and conquences of sleepdeficit.B.The epidemic of sleepiness in the modern times.C.The history of people's sleeping patterns.D.The minimum of our sleeping hours.2.Which of the following is Dr David's opinion?A.People who think they are sleeping enough are better off than tho who don't.B.Some people can remain energetic with only 6.5 hours'sleep a night.C.If they get 18.5 hours'sleep,people will be full of drive and ambition.D.People's metal power suffers if they are lacking in sleep.3.People in the 18th and 19th centuries slept about 9.5 hours a night becau________.A.they were forced by their parents to do soB.they knew what was best for their healthC.they had no electricityD.they were not so dynamic and ambitious as modern people are4.The major cau of sleepdeficit of modern people is________.A.the endless TV programmes in the evenings and the InternetB.the pressures of the dayC.the sufficient energy modern people usually haveD.loud nois in modern cities5.What does the word "subjects" in Paragraph 4 mean?A.Persons or things being discusd or described.B.Branches of knowledge studied in a school.C.Persons or things being treated in a certain way or being experimented on.D.Any member of a state apart from the supreme ruler. 题型:未知难度:其他题型答案
