If you have ever talked about your dreams with your friends, you will find some of your friends don’t remember their dreams, while others can tell their dreams very clearly. Why do people remember dreams differently? The answer is simple: they are two different types of dreamers -low-recall dreamers and high-recall dreamers.

High-recall dreamers reported they remembered their dreams almost every day while low-recall dreams said they only remembered their dreams once or twice a month. 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 more active in high-recall dreamers .This was true both when they were sleeping and awake .This area of the brain is to collect 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(作出反应)more strongly to bearing their own names. When they are sleeping, they can be woken up more easily by sounds and movements

This is not hard to understand. Just try to think of your own sleeping experience. If you’re worried during the night, you are easy to remember your dreams, but if you sleep well, you remember very little in the morning This is because "you never get a chance to remember”

As another research project at the University of Turku in Finland showed, what you dream can also affect our memory. Negative(消极的) dreams are more likely to be recalled than ordinary dreams. Nightmares(噩梦)are often recalled because they are negative, and such dreams cause fear.

1.What can we know about high-recall dreamers?

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

2.Compared to high-recall dreamers, low-recall dreamers_______.

A.have better sleep

B.have more sleepless nights

C.are more easily woken at night

D.respond faster when hearing their names

3.What's the meaning of the underlined word “sensitive"?

A.敏感的 B.迟钝的 C.严重的 D.便利的

4.What did the research project in Finland find?

A.Ordinary dreams can help our brain rest.

B.Ordinary dreams cause fear.

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

D.Negative dreams are easier to remember.

5.What's the main idea of the article?

The energy which the sun radiates(辐射) goes in every direction. But only a minute part of it falls on the earth. Even so, it radiates power of about 5,000,000 horsepower per square mile per day. The sun gives us as much energy every minute as mankind uses in a year. At present, we use this energy indirectly, and it is our final source of power.

Coal(煤) represents the chemical action of the sun on green plants thousands of years ago. Water power results from the rain formed by vapor when water changes into gas under the sunshine. Even windmills(风车磨坊) operate because of air current(流) starts moving by the different heating effects of the sun in different places.

Someday, through chemistry or some types of solar engine, we should use this great source of energy more directly. Already a scientist has worked out an engine, surprisingly doing well, in which the sun’s rays are concentrated through mirrors on water to create steam.

1.What do the underlined words “a minute” mean in this passage?

A.一分钟 B.一点点 C.片刻 D.一份笔记

2.How much energy does the sun radiate every ten square miles per day?

A.About 5,000,000 horsepower B.About 208,333 horsepower

C.About 100,000,000 horsepower D.About 50,000,000 horsepower

3.Which of the following statement is not true, according to the passage?

A.Even windmills turn because of the sun.

B.The sun produces enormous energy for man to make use of.

C.Someday man will be able to use 100% of the solar energy that gets to the earth.

D.The sun produces different heating effects in different places.

4.This passage is mainly about _______.

A.water power B.our final source of power

C.how water power is produced D.the amount of solar energy that can be used
