Question

In our life,they are two different types of dreamer，一low-recall dreamers and high-recall dreamers. According to researchers at the Lyon Nero-science Research Center in France, high-recall dreamers reported they remembered their dreams almost every day while low-recall dreamers said they only remembered their dreams once or twice a month, reported Live Science.

Perrine Ruby,a lead scientist at the research center in Lyon, studied 41 people (21 high-recall dreamers and 20 low-recall dreamers) and recorded their brain activity. She found that a part of the brain called the temporo-parietal junction ( 颞顶叶交界处）was more active in high-recall dreamers. This was true both when they were sleeping and awake. This area of the brain is responsible for collecting and processing information from the outside world. This means that high-recall dreamers are more sensitive to what is happening around them. For example, when they are awake, they respond more strongly to hearing their own names. When they are sleeping, they tend to be woken up more easily by sounds and movements.

By closely studying people’s brain activity, Ruby found that high-recall dreamers have twice as much “wakefulness time” during sleep as low-recall dreamers do. And it is during these short periods of wakefulness that the brain memorizes dreams.

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

As another research project at the University of Turku in Finland showed, dream content can also affect our memory. Negative dreams are easier to recall than ordinary dreams. Nightmares are often recalled because they are emotionally negative, and such dreams cause fear.

1.What can we know about high-recall dreamers according to the article?

A. They have very little brain activity when they sleep.

B. They can remember their dreams clearly.

C. They don’t know how to describe their dreams.

D. They can’t remember their dreams.

2.Which is true about low-recall dreamers compared to high-recall dreamers?

A. They have higher quality sleep.

B. They have more sleepless nights

C. They are more easily woken at night.

D. They respond faster when hearing their names.

3.What is the main purpose of the second to last paragraph?

A. To explain Ruby’s findings.

B. To attract readers^, interest in future studies.

C. To show the advantages of being a low-recall dreamer.

D. To suggest what to do to become a low-recall dreamer.

4.What did the research project in Finland find?

A. Ordinary dreams can help our brain rest.

B. Dreams are often affected by our emotions.

C. Nightmares often happen when we don't sleep well.

D. Negative dreams are more likely to be recalled.

【解析】

本文是一篇科普类说明文。研究表明，做梦的人可以分为高回忆型和低回忆型。高回忆型做梦者比较敏感，睡觉质量不高，总能记得自己的梦是什么样的，而低回忆型的做梦者记不住梦的内容。

1.细节理解题。根据第一段中的high-recall dreamers reported they remembered their dreams almost every day可知，高回忆型的做梦者说他们记得每一天的梦，故选B。

2.推理判断题。根据第四段中的if you sleep well and soundly, you tend to remember very little in the morning.可知，如果睡得很香甜，就记不住梦的内容。而低回忆型的做梦者就是记不住梦的内容，由此可以推断他们的睡觉质量很高。故选A。

3.写作目的题。第二段的首句Perrine Ruby,a lead scientist at the research center in Lyon, studied 41 people (21 high-recall dreamers and 20 low-recall dreamers) and recorded their brain activity.就说明了Ruby做了一个研究，而下面几段就是具体介绍了研究的内容以及结果等。故选A。

4.细节理解题。根据最后一段As another research project at the University of Turku in Finland showed, dream content can also affect our memory. Negative dreams are easier to recall than ordinary dreams.可知，芬兰的研究项目发现消极的梦更容易被想起来。故选D。
