Advice to “sleep on it” could be well founded, scientists say. After a good night’s sleep, a problem, which couldn’t be solved the night before, can often seem more manageable, although the evidence until now has been anecdotal (个人体验的). But researchers, at the University of Luebek in Germany, have designed an experiment that shows a good night’s sleep can improve insight (顿悟) and problem-solving.
“If you have some newly-got memories in your brain, sleep acts on these memories and restructures (重新组织) them, and as a result, after sleep, the insight into problem which you could not solve before increases,” said Dr Jan Born, a neuroscientist (神经科学家), at the university.
To test the theory, they taught volunteers two simple rules to help them turn a string of (一连串) numbers into a new order. There was also a third, hidden rule, which could help them increase their speed in solving the problem. The researchers divided the volunteers into two groups: Half were allowed to sleep after the training, while the rest were forced to stay awake. Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out (想出) the third rule as the other group.
“Sleep helped,” Born said in a telephone interview. “The important thing is that you have to have a memory representation (描绘，表现) of the problem you want to solve in your brain and then you sleep, so it can act on the problem.” But Born admitted that he and his team don’t know how restructuring of memories occurs or what governs it.
Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the anecdotal suggestions that sleep can help develop creative thinking. Although the role of sleep in human creativity will still be a mystery, the research gives people good reason to fully respect their periods of sleep, they added.

The home of the future won’t be completely different and we will be living in houses and flats just as we do today．But people will want to shape their homes to match their dreams．No two homes will be the same．People will be able to buy “house kits” containing a basic house structure, with movable walls, doors and windows．They will put together the different parts to create the home they want．
Many jobs that we do today will disappear, others will still exist but will change and new jobs will be created. Skilled workers such as builders, gardeners and electricians won’t disappear because machines can’t replace them. Teachers will still exist because students need human contact. But they will be using modern technology in class more and students will be working more from home. The medical technology revolution and space travel will create new jobs which we can only imagine today．
Space holidays will develop in the future, but these holidays won’t be for everyone because they won’t be cheap. Short space trips will develop first, then space hotels will orbit the earth where it will be possible to have a longer vacation. By the end of the next century, there will be holiday centres on the moon with leisure facilities for families．
Paper won’t exist in the future. Instead, there will be e-paper which people will be able to use over and over again. This will develop in order to save natural resources. E-newspapers and e-magazines will replace traditional newspapers and magazines and we will download information and news articles from the Internet every day onto our reuseable paper．
The laws of physics tell us that the earth is going to disappear some time in the future．This isn’t going to happen tomorrow but scientists predict that it will happen in five billion years when our sun explodes (爆炸)．We will have to explore the universe and find another home. At some point in the distant future, either we stay on the earth and die with it, or we leave and move to another planet. There won’t be any other choice.Homes of the future will ________．
| A．be completely different from those of today |
| B．be very similar to our homes |
| C．all be different from one another |
| D．be movable as you want |
Space trips and staying in space hotels will ________．
| A．become a very common way to spend a holiday |
| B．be the best holiday option for families |
| C．attract a lot of people |
| D．still only be for very rich people |
E-paper will replace traditional paper because ________．
| A．we will use it again |
| B．it won’t waste natural resource |
| C．it will be cheaper to produce |
| D．it will be convenient to carry |
We will have move to another planet ________．

As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through life, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health．
The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities, others lose heart at the first sign of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between “flight or fight” and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Since we can't remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it．People are finding less and less time for relaxing themselves because ________.
| A．they regard working as their greatest enjoyment |
| B．they believe that work is superior to relaxation |
| C．they are traveling fast all the time |
| D．they are becoming busier with their work than ever before |
According to the author, the most important character for a good manager is his________.
| A．strong will to hold out stress |
| B．knowing the art of relaxation |
| C．high sense of responsibility |
| D．having control over performance |
Which of the following statements is TRUE, according to the passage?
| A．We can find quite a few ways to avoid stress． |
| B．Stress is always harmful to people's health |
| C．It’s easy to change the habit of keeping oneself busy with work． |
| D．Different people can bear different amount of stress． |
In the last sentence of the passage, “do so” refers to ________.
| A．“expose ourselves to stress” |
| B．“find ways to deal with stress” |
| C．“remove stress from our lives” |
| D．“establish links between diseases and stress” |
The story goes that some time ago, a man punished his 3-year-old daughter for wasting a roll of gold wrapping paper．Money was tight and he became infuriated（愤怒的） when the child tried to decorate a box to put under the Christmas tree．Nevertheless, the little girl brought the gift to her father the next morning and said, “This is for you, Daddy.”
The man was embarrassed by his earlier overreaction, but his anger flared again when he found out the box was empty．He yelled at her, stating, “Don't you know, when you give someone a present, there is supposed to be something inside?” The little girl looked up at him with tears in her eyes and cried, “Oh, Daddy, it’s not empty at all．I blew kisses into the box. They’re all for you, Daddy.”
The father was crushed．He put his arms around his little girl, and he begged for her forgiveness．
Only a short time later, an accident took the life of the child．It is also told that her father kept that gold box by his bed for many years and, whenever he was discouraged, he would take out an imaginary kiss and remember the love of the child who had put it there．
In a very real sense, each one of us, as humans beings, have been given a gold container filled with unconditional love and kisses from our children, family members, friends, and God．There is simply no other possession, anyone could hold, more precious than this．The 3-year-old girl was punished by her father for ________．
| A．decorating a box |
| B．wasting wrapping paper |
| C．putting the box under the Christmas tree |

Michael Fish may soon be replaced as a weather forecaster by the shark (鲨鱼).
Research by a British biology student suggests that sharks could be used to predict storms. Lauren Smith, 24, is close to completing her study on shark’s ability to sense pressure. If her studies prove the theory, scientists may be able to monitor the behavior of sharks to predict bad weather.
Miss Smith had previously studied the behavior of lemon sharks in the Bahamas.
She then used their close relatives, lesser spotted dogfish, for further research at Aberdeen University.
Her work---thought to be the first of its kind to test the pressure theory ---- resulted from the observation that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001.
Miss Smith said: “I’ve always been crazy about traveling and diving and this led me to an interest in sharks.”
“I was delighted to have been able to research in the area for my degree. I know there’s so much more we need to understand ---- but it certainly opens the way to more research.”
It has been discovered that a shark senses pressure using hair cells in its balance system.
At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.
In Aberdeen, she was able to study the effects of tidal (潮汐的) and temperature changes on dogfish----none of which were harmed. She also used a special lab which can mimic (模拟) oceanic pressure changes caused by weather fronts.
She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.The passage is most probably taken from _______.
| A．a short-story collection |
| B．a popular science magazine |

Once there was an 11-year-old boy who went fishing with his father in the middle of a New Hampshire lake. On the day before bass (巴斯鱼) season opened, they were fishing early in the evening, catching other fish with worms. Then the boy tied on a small silver lure (鱼饵) and put it into the lake. Suddenly he felt that something very big pulling on the lure. His father watched with admiration as the boy skillfully brought the fish beside the bank. Finally he lifted the tired fish from the water. It was the largest one he had ever seen, but it was a bass.
The boy and his father looked at the big fish. The father lit a match and looked at his watch. It was 10 p.m.—two hours before the season opened. He looked at the fish, then at the boy. “You’ll have to put it back, son,” he said.
“Dad!” cried the boy. “There will be other fish,” said his father. “Not as big as this one,” cried the boy. He looked around the lake. No other fishermen or boats were in sight in the moonlight. He looked again at his father.
Even though no one had seen them, nor could anyone ever know what time he had caught the fish, the boy could tell from his father’s voice that the decision couldn’t be changed. He threw the huge bass into the black water. The big fish disappeared. The boy thought that he would never again see such a big fish.
That was 34 years ago. Today the boy is a successful architect in New York City. He often takes his own son and daughters to fish at the same place.
And he was right. He has never again caught such a large fish as the one he got that night long ago. But he does see that same fish ... again and again ... every time he has an ethical (道德的) decision to make. For, as his father had taught him, ethics are simple matters of right and wrong. It is only the practice of ethics that is difficult. What happened when the big fish turned out to be a bass?
| A．The boy and his father discussed what to do with the big fish. |
| B．The boy threw the bass back into the water willingly. |
| C．The father lit a match in order to check the time. |
| D．They worried other fishermen may discover what they had done. |
From the text we know that the father _________.
| A．didn’t love his son |
| B．always disagreed with his son |
| C．disliked the huge fish |
| D．was firm and stubborn |
How did the boy feel when the huge bass was thrown into the water?
