Question

You’d think the human race would have understood sleeping very well by now, but many of us are still sleeping poorly. Part of the problem is that we have wrong information and beliefs about this important health need. Let’s set the facts straight. 1.

1. More sleep is better for you.

There could be such a thing as too much sleep. The amount of sleep we need varies by person and also changes as we age. Harvard researchers found that a lot of sleep (9 hours or more) is linked with poor sleep quality. 2. Aim for better sleep.

2. 3.

Alcohol can help most people fall asleep. However, it also can cause you to wake up more during the night, decreasing your sleep quality. Consider drinking non-alcoholic drink before bed instead.

3. If you wake up in the middle of the night, lie in bed until you eventually fall back asleep.

4. We all hope to quickly fall back asleep. So we tend to stay in bed hoping it’ll happen at any minute now. If that doesn’t happen, though, within 15 minutes, most experts recommend getting out of bed to do something that occupies our bodies and brains without overstimulating us. Try not to check the clock either.

.4. You can catch up on sleep on weekends.

When we lose sleep during the week, we accumulate a kind of sleep ＂debt＂. 5.     Not so fast. This might actually make you sleepier the next week. Instead of waking up later on the weekends, you’d better go to sleep earlier or perhaps take a nap in the afternoon.

A. Alcohol helps you sleep.

B. Here are some things you might have been told about sleeping but aren’t completely true.

C. Everyone should get 7—8 hours of sleep per night.

D. So don’t aim for more sleep — even on the weekends.

E. Waking up in the middle of the night is the pits (烦心事), but it happens to all of us.

F. You’ll have a better day and perhaps sleep better at night.

G. Can you pay that debt back by sleeping on Saturday or Sunday?

【解析】

本文是一篇说明文，现代社会很多人的睡眠不好，部分原因是人们对睡眠有一些错误的观点。本文介绍了其中4个错误看法。

1.根据本段第二局“Part of the problem is that we have wrong information and beliefs about this important health need.”可知人类睡眠不好的部分原因是人们对于睡眠有错误的了解。2-4段即为人们对睡眠的一些错误看法。B项“Here are some things you might have been told about sleeping but aren’t completely true.”很好地把第一段和2-4段串联在一起。

2.横线前一句“Harvard researchers found that a lot of sleep (9 hours or more) is linked with poor sleep quality.”告诉我们睡觉太久通常睡眠的质量较差。也就是不要睡的太久。故D项符合上下文串联。

3.根据本段第二局However, it also can cause you to wake up more during the night, decreasing your sleep quality.有时候酒精会让你半夜醒过来，反而影响你的睡眠。说明人们通常会人物酒精有助睡眠，而这种看法通常是错误的。故A项符合上下文串联。

4.本段的主题是“If you wake up in the middle of the night, lie in bed until you eventually fall back asleep”如果半夜醒来，一直躺在床上直到睡着。本段首句内容应该与此有关，故E项“Waking up in the middle of the night is the pits (烦心事), but it happens to all of us.”符合中心思想。

5.本段中提出很多人认为我们可以在周末补交，把以前损失的睡眠弥补回来。而这种看法是错误的。在根据横线前句“当我们工作日损失了睡眠，我们积累了睡眠“债”。”可知本句应该是G项“我们能否通过周末睡觉来还债？”与本段中心思想完全一致。
