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 less sleep than they ought to." says Dr. David.
The beginning of our sleep deficit crisis can be【C1】______to the invention of the light bulb a century ago. From diary entries and other personal【C2】______from the 18th and 19th centuries, sleep scientists have reached the conclusion that the average person used to sleep about 9.5 hours a night. By the 1950s and 1960s, that sleep schedule had been reduced【C3】______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【C4】______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【C5】______
Perhaps the most merciless robber of sleep, researchers say, is the【C6】______of the day. Whenever pressures from work, family, friends and community mount, many people consider sleep the least【C7】______item on the agenda. "In our society, you’re considered dynamic 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【C8】______and ambition."
To assess the【C9】______of sleep deficit, researchers have put subjects through a set of psychological and performance tests. "We’ve found that if you’re sleep-deprived, performance【C10】______says Dr.
David. "Short-term memory is impaired, as are abilities to make decisions and to concentrate."
A)consequences B)complexity C)ingenious D)dramatically
E)suffers F)tracked G)realize H)expensive
I)slightly J)traced K)detaches L)vigorous
M)inspiration N)accounts O)drive
【C8】
选项
答案
O
解析
此处需填入与ambition(抱负)并列的抽象名词,作lack的宾语。drive作名词时意为“干劲”,符合此处语境,表示“如果你说要睡8.5小时,人们就会觉得你缺少干劲和抱负”。
