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."

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 [br] 【C5】
选项
答案
L
解析
此处需填入名词、形容词或分词,作feel的表语。本句意为:他们认为睡6.5小时也没有问题(okay),而实际上他们需要睡7.5或8个小时,甚至更多才能感觉……。由前后两个时间的对比和空格前的ideally(理想地)可知,vigorous“精力充沛的”符合句意。
