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 single study that hasn’t found Americans getting【C1】________sleep than they ought to." says Dr. David.
【C2】________people who think they are sleeping enough would probably be【C3】________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【C6】________that the average 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 even【C9】________they’re doing it," says Dr. David. "They think they’re okay because they can【C10】________on 6.5 hours, when they really need 7.5, 8 or even more to feel ideally【C11】________."
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【C14】________item on the agenda. "In our society, you’re considered【C15】________if 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."
【C7】
选项
A、reinforced
B、forced
C、relied
D、counted
答案
B
解析
根据本题后半句“那时,人们晚上不用下地干活而且到处一片漆黑”可知,当时人们形成最好的睡眠习惯是环境所迫,故选B项forced,force…on“把……强加于”。A项reinforced“加强,增强”不与habits搭配,且不与on连用。rely on“依赖,依靠”(C项)。count on“依靠,指望”(D项),这两项代入句中意思不通。
