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.

A)consequences B)complexity C)ingenious D)dramatically
E)suffers F)tracked G)realize H)expensive
I)slightly J)traced K)detaches L)vigorous

【C4】
选项
答案

解析
