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.

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] 【C7】
选项
答案
