Sleep Deficit(不足)
Judging from recent surveys, most experts in sleep behavior agree that is virtually an epidemic 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 sleep-deficit crisis can be traced to the invention of the light bulb a century ago. From diary entries and other personal accounts from the 18th 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9. 5 hours a night. "The best sleep habits once were forced on us, when we had nothing to do in the evening down on the farm, and it was dark. " By the 1950s and 1960s, that 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 on their sleep, and they don’t even realize they’re doing it, " says Dr. David. "They think they’re okay because they can get by on 6. 5 hours, when they really need 7. 5, 8 or even more to feel ideally vigorous. "
"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 least expensive item on his program. "In our society, you’re considered dynamic if you say you only need 5. 5 hours’ sleep. If you’ve got to get 8. 5 hours, people think you lack drive and ambition. "
To determine the consequences of sleep deficit, researchers have put subjects through a set of psychological and performance tests requiring them, for instance, to add columns of numbers or re call a page read to them only minutes earlier. "We’ve found that if you’re in sleep deficit, performance suffers, " says Dr. David. "Shot-term memory is weakened, as are abilities to make decision and to concentrate.
According to Dr. David, Americans ______.
选项
A、are ideally vigorous even under the pressure of life
B、often neglect the consequences of sleep deficit
C、do not know how to relax themselves properly
D、can get by on 6. 5 hours of sleep
答案
B
解析
推断题。在第二段后半部分中大卫博士提到其实在睡眠上人们在自欺欺人,只是他们没有意识到而已,并且人们认为每天睡6. 5小时他们完全可以应付。事实上。要确保精力充沛,他们需要7. 5至8小时,甚至更长时间的睡眠。在第3段中,大卫博士指出,每当面对工作、家人、朋友和社会的巨大压力时,很多人认为睡眠是最不重要的,是最可以有弹性的。由此不难得出结论,美国人不在乎睡眠不足的后果或对此视而不见,因此B符合文意。
