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.

In Germany, English expressions are used in conversations and increasingly in written form. Advertisements are often expressed completely in English. When I go to the gym, there are “aerobic-classes (增氧健身法课程)”. We “warm up”. We go “jogging.” In business, we attend a “meeting” and we have “good connections.”
Other nations, like France, have taken action to protect their language from the influence of “Americanization”. In Germany, however, there is concern that those rules could be connected with Hitler’s Third Reich (帝国), when the language had to be pure. If the government curbed（限制）the use of English words now, this could be considered by some as a return to that terrible past.
Some German citizens are now trying to stop the use of English vocabulary in German. However, I think generally it is not a big deal to use some common English expressions as they often describe things more directly. But we should know that it is important to use English correctly. All too often, bad English is spoken or even written instead of good German. The proper use of the German language would be the better choice. However, there are some fields that require the use of English words, for example, in the high-tech communication and the Internet fields, there is no alternative to English. Also, I think sometimes I have to speak English when I introduce some scenic places to tourists.
I think you have to find a balance and decide when it is better to use good German in place of bad English or when the use of correct English words is more suitable. Languages have always changed naturally, and I disagree with a restriction by law. Some nice expressions borrowed from other languages can make a conversation more vivid.

I had never seen sand dunes（沙丘）before. If you go to the seaside in Britain, you may see some small hills of sand, but nothing very impressive. Of course, Africa is home to many beautiful “sandscapes”, but I was in China, so I went to Dunhuang.
I had spent my first day looking at the beautiful Mogao caves. Now I wanted to experience something very different.
I have been walking in Asia, Europe and America, but nothing prepared me for walking over hills of sand. Whenever I took a step up a hill, my feet would sink into the sand and move backwards. Sometimes it seemed as if I were moving in the wrong direction.
I wanted to see the sunset so I had to climb to the top of the highest sand dune. The sun was beating down upon my back as I walked slowly over the sand. Some plants had managed to survive in the dry ground but not many.
As I climbed higher, the hills of sand became steeper and my feet started to slip further backwards. I ended up with my hands and knees, crawling (爬行)upwards through the top. I just let go if I would fall the way down. But I refused to give up: inch by inch, I made my way to the top of the sand dune.
When I got there I was amazed by what I saw. The sand formed a very sharp point, just like a knife-edge. One side of the dune was bathed in sunshine, the other covered by shade. As I looked into the distance, the same pattern was repeated on all of the hilltops, and the difference between dark and light was beautiful.
As the sun began to sink, the shadows grew longer and the light became warm and orange. The wind had come to life and sand was blown against my legs as I walked along the dunes. Soon it was getting dark and I could only just make out the line of footprints that marked my journey to the top of the hill. I slowly made my way down to the bottom, my path lit by the dying sun.

If you are in charge of a project, the key to success is getting everyone to want to help you. As a director, I point, I suggest. I gently push the actors in the direction I want them to go. In the 1986 movie, “Nothing in Common”, Jackie Gleason’s character, Max Basner, gets fired from his job as a clothing salesman. The scene, shot on a boat, shows Max’s despair about being out of work. I was looking for some gesture that would allow Max to show his feelings.
Jackie had far more experience at everything than I did, and at first I was frightened. What could I possibly tell “The Great One” about acting? Finally I decided to direct by suggestion, and sat down with Gleason to talk about the scene. “So Max is sad, right?” I said.
Gleason nodded.
“And he’s probably still carrying his pens with name on them—the ones he used to hand out to his customers, right?”
Gleason nodded.
“So what would you want to do with the pens after you were fired?”
He was silent for a moment. “Why don’t I throw them overboard?”
I stood up and turned up and turned toward the crew. “Hey, everybody, Jackie has a wonderful idea. Let’s shoot it.”
After filming the scene, Gleason called me over and said with a smile. “Garry, what kind of wonderful idea am I going to have tomorrow?”
You and your team can discover the answers to problems together. When there are no prizes or gold stars for who gets the solution first, you’ll all benefit when everything turns out right.

In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartments. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent-controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.
Some theorists argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low-paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. The price, which is the wage that employers must pay, increases. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim, an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.
Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.
Economic theory predicts the results of economic d
ecisions such as decisions about farm production, rent control, and the minimum wage. The predictions may be correct only if “other things are equal”. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.There is the possibility that setting maximum rent may.
a. cause a shortage of apartments

loyment will arise .
a. if the minimum wage is set too high
b. if the minimum wage is set too low
c. if the workers are unskilled
d. if the maximum wage is setWhich of the following statements is NOT true?
a. The results of economic decisions can not always be p
redicted.
b. Minimum wage can not always protect employees.
c. Economic theory can predict the results of economic decisions if other factors are not changing.
d. Economic decisions should not be based on economic theory.
As we have seen, the 
focus of medical care in our society has been shifting from curing disease to preventing disease – especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most ni
ghts but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.
The field of medicine 
has not traditionally distinguished between someone who is merely “ not ill” and someone who is in excellent health and pays attention to the body’s special needs. Both types have simply been called “well”. In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively striving to maintain and improve their health. People who are well are concerned with nutrition and exercise and theymake a point of monitoring their body's condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap may be "well," in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. "Wellness" may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life.Today medical care is placing more stress on______.
a. keeping people in a healthy physical condition
b. monitoring patients' body functions
c. removing people's bad living habits
d. ensuring people's psychological well-beingIn the first paragraph, people are reminded that_____.
a. good health is more than not being ill

a. does not have any unhealthy living habits
b. does not have any physical handicaps
c. is able to handle his daily routines
d. is free from any kind of diseaseAccording to what the author advocates, which of the following groups of people would be considered healthy?
a. People who have strong muscles as well as slim figures.
b. People who are not presently experiencing any symptoms of disease
c. People who try to be as possible, regardless of their limitations.
d. People who can recover from illness even without seeking medical care.
