HOW would you like to step into the world of other people’s dreams? That’s just what Dom Cobb (Leonardo DiCaprio) does. His work is to steal secrets from people when they are asleep and dreaming. He has an even rarer ability: He can plant an idea in someone’s sleeping mind, and watch it grow and take root in reality. This ability is called inception.

The movie Inception (《盗梦空间》) was on show in Chinese cinemas not long ago. It is imaginative, of course. The movie leads one to wonder just how much we know about dreams. For years, scientists and researchers have been trying to solve sleep’s greatest mystery.

Is it possible to enter someone’s dreaming mind? In the movie, DiCaprio uses a drug and a dream machine to put a scenario (某一特定情节) into someone’s sleeping mind. He then goes to sleep himself, connected to the machine, and enters the other person’s dream.

In real life, there is a machine that can read someone’s mind. A brain scanner takes pictures of brain activity, and then the software recreates images of what the person was looking at.

Researchers say it may be possible one day to record someone’s dream – without the danger (or the fun) of actually sharing that dream.

What’s a dream, anyway? A dream is a group of images and sounds our brain creates when we’re sleeping. In the 1950s, researchers discovered a sleeping condition that happened around every 90 to 120 minutes during sleep: rapid eye movement, or REM. During this period you’re fast asleep, yet your eyes move around quickly under your eyelids (眼皮) and your brain is nearly as active as during the day. That’s when most dreams happen.

What do dreams mean? Dreams are not always filled with meaning. Sometimes dreams are just your mind playing with thoughts and images from your life, or things you may have read or seen on TV. But at other times, dreams show things that you want to achieve in real life, or things that cause you trouble or stress.

The movie Inception is mentioned at the beginning of the article to ______.

       A. encourage readers to watch the movie

       B. tell readers about people with special dreaming abilities

       C. inform readers about the science of dreams

       D. warn reader about the threat of dream stealers

According to the article, how does a brain scanner work?

       A. It records dreams.

       B. It uses a special drug that causes no pain.

       C. It finds out what dreams mean.

       D. It takes pictures of brain activity and recreates images.

According to the article, which of the following statements about REM sleep is TRUE?

       A. Most dreams occur in REM sleep.

       B. Over the last ten years scientists have solved the mystery of REM sleep.

       C. People always remember what they have dreamed in a REM sleep.

       D. People can have REM sleep all night.

The article claims that ______.

       A. dreams tell us a lot about a person’s character

       B. dreams are connected to real life

       C. dreams are useful and help keep our brains active

       D. dreams are usually about meaningful things

 Space is a dangerous place. not only because of meteors (流星) but also because of rays from the sun and other stars. The Atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.

    Radiation is the greatest known danger to explorers in space. The unit of radiation is called “rem”. Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed (畸形的) children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys, the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.

1. According to the first paragraph, the atmosphere is essential to man in that ______.

A. it protects him against the harmful rays from space    

B. it provides sufficient light for plant growth

C. it supplies the heat necessary for human survival      

D. it screens off the falling meteors

2. It can be inferred from the passage that ________.

A. the Apollo mission was very successful        

B. protection from space radiation is no easy job

C. astronauts will have deformed children or grandchildren

D. radiation is not a threat to well-protected space explorers

3. The best title for this passage would be ________.

A. The Atmosphere and Our Environment   B. Research on Radiation.

C. Effects of Space Radiation             D. Importance of Protection Against Radiation

If you dream in color, you’re not alone: the majority of people today claim to have colorful dreams. But it wasn’t always thus. Research conducted in the early part of the last century consistently found that people reported dreaming most often in black and white.

According to Eva Murzyn at the University of Dundee, there are at least two possible explanations for this strange situation.

The first is the methods used in the researches. The early studies tended to use questionnaires（问卷）, while more modern studies use dream diaries (filled in upon rising in the morning) or so-called “REM-awakening”, which involves interrupting people’s dream-filled periods of sleep to find out what they were dreaming about. People’s memories of their dreams are likely to be less accurate by using the questionnaire approach and they are more likely to reflect their beliefs about the form dreams generally take in an unclear way.

The second explanation has to do with black and white television and film. It's possible that the sudden increase in black and white film and television during the first half of the last century either affected the form of people’s dreams at that time, or affected their beliefs about the form dreams generally take.

According to Murzyn’s findings, it’s the explanation based on media exposure that carries more weight. She used both questionnaire and diary methods to study the dreams of 30 older (average age 64) and 30 younger people (average age 21).

The methodological technique made no difference to the type of dreams people reported. However, the extremely important thing was that, across both questionnaires and diaries, the older participants (who had had significant early life exposure to black and white media) reported experiencing significantly more black and white dreams over the last ten days than the younger participants (22 per cent vs. 4 per cent).

Another finding was that older participants reported black and white dreams and colorful dreams to be of equal clearness. By contrast, the younger participants reported that the quality of black and white dreams was poorer. This raises the possibility that the younger participants didn’t really have any black and white dreams at all, but were simply regarding poorly remembered dreams as black and white.

1.We learn from the text that ______.

       A. people in the first half of the last century never had colorful dreams

       B. older people are more likely to have black and white dreams

       C. the dreams of younger people are always colorful

       D. people today don’t have white and black dreams any more

2.What did Murxyn do to find out the explanations for the colors in people’s dreams?

       A. She applied both questionnaire and diary methods to study people’s dreams.

       B. She used diary methods to record people’s dreams.

       C. She chose 60 people to answer her questions about their dreams.

       D. She woke people up to record the colors of their dreams.

3.What does the underlined expression “carry more weight” in paragraph 5 mean?

       A. be heavier  B. be more powerful      C. be more important     D. be more useful

4.From Murxyn’s findings we can infer that ______.

       A. both older people and younger people could report colorful dreams clearly

       B. young people don’t have any black and white dreams in fact

       C. the color of a person’s dream is decided by one’s age

       D. it is probably the color of media that affects the color of one’s dream
