The Earth’ s daily clock, measured in a single revolution, is twenty-four hours. The human clock,【B1】______, is actually about twenty-five hours. That’ s 【B2】______ scientists who study sleep have determined from human subjects who live for several weeks in observation chambers with no【B3】______of day or night. Sleep researchers have 【B4】______ other surprising discoveries as well.
We spend about one-third of our lives asleep, a fact that suggests sleeping, 【B5】______ eating and breathing, is a fundamental life process. Yet some people almost never sleep, getting by on as 【B6】______ as fifteen minutes a day. And more than seventy years of【B7】______into sleep deprivation, in which people have been kept【B8】______for three to ten days, has 【B9】______ only one certain finding: Sleep loss makes a person sleepy and that’ s about all; it causes no lasting ill【B10】______. Too much sleep, however, may be【B11】______for you.
These findings【B12】______some long-held views of sleep, and they【B13】______questions about its fundamental purpose in our lives. In【B14】______, scientists don’t know just why sleep is necessary..
Some scientists think sleep is more the result of evolutionary habit than【B15】______actual need, Animals sleep for some parts of the day perhaps because it is the 【B16】______ thing for them to do: it keeps them【B17】______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【B18】______and had little reason to question the reason or need for【B19】______. But the development of the electroencephalograph and the resulting discovery in 1937 of dramatic【B20】______in brain activity between sleep and wakefulness opened the way for scientific inquiry in the subject.

选项
A、effects
B、affections
C、influences
D、impacts
答案
A
解析
考查固定搭配。此处句意为“缺乏睡眠让人犯困,仅此而已;没有长期的______”。ill effects为固定搭配,意为“副作用,负面影响”。故A.effects符合题意,为正确答案。affection“喜爱;喜欢”,influence“影响,势力”,impact“影响,作用”,均无此用法,故排除。
