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.

Burning the midnight oil before an exam or interview has an opposite effect according to a research which found that sleep is necessary for memories to be “downloaded” into the brain.

“A good night's sleep within 30 hours of trying to remember a new task is a necessary condition of having good recall in the weeks ahead，” scientists have found.

“We think that getting that first night's sleep starts the process of memory consolidation(加强)，” said Robert Stickgold, a sleep researcher at Harvard Medical School who conducted the latest study.

“It seems that memories are normally washed out of the brain unless some process nails them down. I feel uncertain that sleep is one of those things that do the nailing down，” Professor Stickgold said.

Professor Stickgold's team trained the 24 people to tell the direction of three diagonal bars (斜线) shown for a sixtieth of a second on a computer screen full of horizontal stripes(水平线)．

Half the subjects were kept awake that night, while the others slept. Both groups were allowed to sleep for the second and third nights to make up for any differences in tiredness between the volunteers.

Those who slept the first night were much better at remembering the task while the second group showed no improvement in spite of enjoying two nights of catch－up sleep.

A further study by scientists at the Medical University at Lubeck in Germany showed that memories are laid down in two stages during the night. The first is during the deep, so－called “slow wave” sleep, which usually takes place in the first half of the night. The second, and less important stage happens during the periods of dreaming or “rapid eye movement (REM)”. When people don't sleep well in the first half of the night, their memory consolidation is almost the same as having no sleep at all.

B. Sleep speeds up the loss of memory.

C. Man should have a good sleep if he wants to keep a good memory.

D. Staying up late will make you better prepared for an exam or interview.

2. It can be inferred from the fourth paragraph that________.

A. some process helps memories to be washed out of the brain

B. Professor Stickgold is doubtful about whether sleep can make memories worse

C. some memories normally influence the function of the brain

D. sleep may can improve the condition of memories

3. How was the research conducted by Professor Stickgold?

A. The subjects were divided into two groups.

B. All the subjects were kept awake for 3 nights.

C. One group slept at the first night but was kept awake the next two nights.

D. One group was kept awake for 3 nights but the other slept for the second and third nights.

4. What was the study result of the scientists' at the Medical University at Lubeck?

A. REM sleep is not important at all for the consolidation for memory.

B. Intellectual performance mainly depends on the slow wave sleep period.

C. When people sleep poorly in the first half of the night, it is almost the same as having no sleep at all.

D. REM sleep is as important as slow wave sleep in terms of memory recall.

5. The BEST title of this passage is “________”．

A. Sleep Necessary for Memories

B. The Importance of the First Stage of Sleep

C. Studies Made by Scientists About Sleep

D. The Scientists' Achievement in Sleep Research

The Meanings of Dreams
Sleep and dreams have interested people for centuries. Scientists are learning more about sleep, but they still know very little about why we dream.
   【小题1】   First, we have most of our dreams during REM (rapid eye movement) sleep. At this time, the brain is very active. Second, everyone dreams – even if we cannot remember doing so when we awaken.    【小题2】   While we are asleep, it works more slowly and sometimes puts our thoughts and memories together in strange ways.
   【小题3】   Some believe that our dreams are associated with thoughts and feelings that we experience while we are awake. Many dream researchers think that a dream about death, for example, is really about an important life change.    【小题4】   Dreams about a car or travel often represent feelings about your own life. Dreams about teeth – especially broken or loose ones may indicate stress and fear. Dreams in which you are flying often represent freedom or escape.
Researchers think people in our dreams can tell us something about ourselves. If the person in the dream was yelling (叫喊), for example, maybe you are angry.    【小题5】
There is still a lot about dreaming that we do not understand. By learning more about our dreams, we may learn more about ourselves.

A．Dreams may be more important than sleep.

B．Scientists do not know for certain why we dream.

C．If he or she was terrified, then maybe you are afraid of something.

D．Modern research can tell us some important things about dreams.

E. There are three things you should pay attention to to have a sweet dream.
F. Finally, a part of our brain helps us to understand daily experiences we have.
G. Dreams about telephones are thought to be about giving or receiving an important message.
