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【C1】________sleep than they ought to." says Dr. David.
【C2】________people who think they are sleeping enough would probably be【C3】________with more rest.
The beginning of our sleep deficit crisis can be【C4】________to the invention of the light bulb a century ago. From diary entries and other personal【C5】________from the 18th and 19th centuries, sleep scientists have reached the【C6】________that the average person used to sleep about 9.5 hours a night. "The best sleep habits once were【C7】________on us, when we had nothing to do in the evening down on the farm, and it was dark." By the 1950s and 1960s, that sleep schedule had been reduced【C8】________, 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【C9】________they’re doing it," says Dr. David. "They think they’re okay because they can【C10】________on 6.5 hours, when they really need 7.5, 8 or even more to feel ideally【C11】________."
Perhaps the most merciless robber of sleep, researchers say, is the【C12】________of the day. Whenever pressures from work, family, friends and community【C13】________, many people consider sleep the least【C14】________item on the agenda. "In our society, you’re considered【C15】________if you say you only need 5.5 hours’ sleep. If you say you’ve got to get 8.5 hours, people think you lack【C16】________and ambition."
To assess the【C17】________of sleep deficit, researchers have put subjects【C18】________a set of psychological and performance tests requiring them, for instance, to add columns of numbers or recall a passage read to them only minutes earlier. "We’ve found that if you’re sleep-deprived, performance【C19】________," says Dr. David. "Short-term memory is impaired,【C20】________are abilities to make decisions and to concentrate."
【C18】
选项
A、down
B、across
C、through
D、among
答案
C
解析
本题空格前的subjects指“实验对象”,解决了这个语言难点,本题就迎刃而解。“通过一组测试”用介词C项through。A项down“沿着,在……下方”通常后接地理位置。B项across“穿过。横穿”与tests无法搭配。D项among代入句中意为“把实验对象放在测试之中”,不合逻辑。
