Question

【題目】D

Do you and your friends ever talk about your dreams with each other? If you do, you might have noticed something interesting – some of your friends seldom remember their dreams, but some can always describe their dreams so clearly that it seems like they’re describing things that really happened to them. What makes those people different?

The answer is simple. There are two different types of dreamers – low dream recallers（回憶者）and high dream recallers.

Low dream recallers usually remember their dreams only twice a month. But high dream recallers are able to remember them about five mornings a week. And a new study suggests that activity in a certain part of the brain could have something to do with it, reported The Huffington Post.

Perrine Ruby, a French researcher at the Lyon Neuroscience Research Center, studied 41 people (21 high dream recallers and 20 low dream recallers) and recorded their brain activity.

She found that a part of the brain called the temporo-parietal junction (顳頂聯(lián)合區(qū)) was more active in high dream recallers than in low dream recallers – both when they were sleeping and awake.

This brain area collects and processes（編程）information from the outside world. This means that high dream recallers know more about what’s happening around them. For example, when they are awake, they respond (對……有反應(yīng)) more strongly to hearing their own names, and when they are sleeping, they are woken more easily by sounds and movements.

By closely studying people’s brain activities, Ruby found that high dream recallers have twice as much “wakefulness time” during sleep as low dream recallers do. And it is during these short times of wakefulness that the brain remembers dreams.

“The sleeping brain is not able to remember new information,” Ruby told The Washington Post. “It needs to wake up to be able to do that.”

This is not hard to understand. Just try to think of your own sleeping experiences. If you are worried during the night, you are more likely to remember your dreams, but if you sleep well, you will remember little in the morning, and this is because “you never get a chance to remember”, Robert Stickgold, a Harvard Medical School researcher, told The Washington Post.

【1】According to the article, high dream recallers ______.

A. have very little brain activity during sleep

B. can remember their dreams clearly

C. don’t know how to describe their dreams

D. remember their dreams twice a week

【2】Compared to high dream recallers, low dream recallers ______.

A. have higher sleep quality

B. have more sleepless nights

C. are more easily woken at night

D. respond faster when hearing their names

【3】What is the main purpose of the last paragraph?

A. To show the advantages of being a low dream recaller.

B. To suggest what to do to become a low dream recaller.

C. To make readers interested in future studies.

Answer 1

【答案】

【1】B

【2】A

【3】D

【解析】這是一篇關(guān)于做夢的短文，文中講述了低的夢想回憶者和高的夢想回憶者。文中對于這一現(xiàn)象做了調(diào)查。

【1】根據(jù)文中This brain area collects and processes（編程）information from the outside world. This means that high dream recallers know more about what’s happening around them.可知，高的做夢回憶者能更清晰地記住他們的夢。故選B。

【2】根據(jù)文中Ruby found that high dream recallers have twice as much “wakefulness time” during sleep as low dream recallers do.可知，低做夢回憶者有更好的睡眠質(zhì)量。故選A。

【3】通讀最后一段可知，這里主要是為了證明Ruby的實驗調(diào)查。故選D。
