Judging from recent surveys, most experts in sleep behavior agree that there is virtually an epidemic of sleepiness in the nation. "I can’t think of a【C1】______study that hasn’t found Americans getting less sleep than they ought to," says Dr. David.【C2】______people who think they are sleeping enough would probably be【C3】______off with more rest.
The beginning of our sleep-deficit crisis can be 【C4】______to the invention of the light bulb a century ago. From diary entries and other personal【C5】______from the 18th and 19th centuries, sleep scientists have reached the conclusion that the【C6】______person used to sleep about 9.5 hours a night. "The best sleep habits once were【C7】______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【C8】______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【C9】______they’re doing it," says Dr. David. "They think they’re okay because they can get【C10】______on 6.5 hours, when they really need 7.5, 8 or even【C11】______to feel ideally vigorous."
Perhaps the most merciless robber of sleep, researchers say, is the【C12】______of the day. Whenever pressures from work, family, friends and community【C13】______. many people consider sleep the least expensive item on the【C14】______. "In our society, you’re considered dynamic【C15】______you say you only need 5.5 hours’ sleep. If you say you’ve got to get 8.5 hours, people think you lack【C16】______and ambition."
To assess the【C17】______of sleep deficit, researchers have put subjects【C18】______a set 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 sleep-deprived, performance【C19】______." says Dr. David. "Short-term memory is impaired,【C20】______are abilities to make decisions and to concentrate." [br] 【C19】
选项
A、descends
B、suffers
C、takes
D、makes
答案
B
解析
语义衔接题。由sleep-deprived(睡眠不足)和下句的short-term memory is impaired(短期记忆能力减弱)可知,这里应填一表示不好结果的词,且该词能与performance(表现)搭配,符合这两个要求的只有[B]suffers。
