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.

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
【C4】
选项
答案
G
解析
空格前出现否定助动词don’t,故此处需填入动词原形。上文说人们偷走了(cheat on)睡眠时间,空格前的even“甚至”表示递进关系,realize“意识到”符合句意,表示他们甚至都没有意识到这一点。
