Question

【題目】Who knows about sleep? Astronauts (宇航員). They have to. Their bodies are cut off from the outside world that reminds (提醒) us what time it is. But actually, it's even worse than that. An astronaut reported in his diary that he was likely to make mistakes on days following an unusually late bedtime.

So NASA started doing some serious research. They quickly realized that we're a slave to the outside world. Without light and darkness, we' re unable to regulate (管理) sleep times.

Because of modern technology, we're all living more like astronauts now. Light is no longer a function (功能) of the sun, but of always-on indoor lights, TV and computer screens. Temperature no longer follows a cycle of cooling at night and warming during the day. Is it any wonder that a third of Americans have sleep problems?

Maybe you think this doesn't affect you — or at least not much. You're wrong. Research done on non-astronauts has shown the same thing. After two weeks of six hours of sleep a night; you're drunk. By the end of two weeks, the six-hour sleepers behaved as badly as those who hadn't slept for 24 hours.

But what did they say when asked how they felt? "It's not affecting me." So if you are performing poorly because of sleep problems, you may have no idea. This is a real problem.

So what answers did NASA come up with?

Take an hour to calm down before bed. Yes, you're busy. But your time is not more valuable than an astronaut's.

Keep your bedroom dark, cool and free from noise. Even if you think "the light doesn't affect you" or "the noise isn't that bad", it can still affect sleep quality.

Another advice: forget the alarm clock (鬧鐘) in the morning; set an alarm to remind you to go to bed at night. When it goes off, finish up any work on the computer, and turn off any unnecessary lights. This prevents you from cheating yourself on sleep and allows you to wake up naturally.

【解析】

試題分析:本文通過宇航員的睡眠分析了lingt和darkness對(duì)睡眠的影響,并提出了解決睡眠問題的一些建議。

【1】B 細(xì)節(jié)理解題。根據(jù)第二段“They quickly realized that we're a slave to the outside world. Without light and darkness, we' re unable to regulate (管理) sleep times.” 可知我們的的睡眠完全受外界影響，沒有光明和黑暗，我們就沒法管理睡眠時(shí)間，故選B。

【2】B細(xì)節(jié)理解題。第四段提到如果讓人連續(xù)兩周每天睡六個(gè)小時(shí)，他們的行為會(huì)和24小時(shí)不睡覺的人一樣，而第五段中提到But what did they say when asked how they felt? "It's not affecting me." So if you are performing poorly because of sleep problems, you may have no idea. This is a real problem. 由此可知，他們根本不知道自己睡眠有問題，故選B。

【3】B 細(xì)節(jié)理解題。本句的意思是“但你的時(shí)間比宇航員的時(shí)間還寶貴嗎”，也就是說，你再忙也能找出時(shí)間的，故選B。

【4】A 細(xì)節(jié)理解題。最后一段提到“set an alarm to remind you to go to bed at night.”可知選A。
