The Earth’s daily clock, measured in a single revolution, is twenty-four hours. The human clock, 【C1】______, is actually about twenty-five hours. That’ s【C2】______scientists who study sleep have determined from human subjects who live for several weeks in observation chambers with no【C3】______of day or night. Sleep researchers have【C4】______other surprising discoveries as well.
We spend about one-third of our lives asleep, a fact that suggests sleeping, 【C5】______eating and breathing, is a fundamental life process. Yet some people almost never sleep, getting by on as【C6】______as fifteen minutes a day. And more than seventy years of【C7】______into sleep deprivation, in which people have been kept【C8】______for three to ten days, has【C9】______only one certain finding: Sleep loss makes a person sleepy and that’s about all; it causes no lasting ill【C10】______. Too much sleep, however, may be【C11】______for you.
These findings【C12】______some long-held views of sleep, and they【C13】______questions about its fundamental purpose in our lives. In【C14】______, scientists don’t know just why sleep is necessary.
Some scientists think sleep is more the result of evolutionary habit than【C15】______actual need, Animals sleep for some parts of the day perhaps because it is the【C16】______thing for them to do: it keeps them【C17】______and hidden from predators; it’s a survival tactic. Before the advent of electricity, humans had to spend at least some of each day in【C18】______and had little reason to question the reason or need for【C19】______. But the development of the electroencephalograph and the resulting discovery in 1937 of dramatic【C20】______in brain activity between sleep and wakefulness opened the way for scientific inquiry in the subject.
【C6】
选项
