　　Have you ever felt your mind falling into disorder after a sleepless night? You couldn't come up with an original thought no matter how hard you tried.

　　You were probably right if you thought that was caused by a lack of sleep. Dr. Home,a sleep researcher in England, studied 24 college students. One group got their normal　eight hours of sleep. The other group didn't get the smallest amount of sleep-they stayed awake all night. The next day, Dr, Home tested the students. He asked them question that　required creative and original thinking. One of the questions was "How many uses can a　cardboard box be put to?"

　　The result? The wide-awake students did well on the test. The tired students did　poorly.

　　Research has already shown that tired people can do OK on tests of habitual thinking,like simple addition But Dr. Home tested creative thinking only.

　　As part of his study, he offered an amount of money as reward to the sleepy students　if they did well. But even this encouragement was not enough to help the students conquer　their tiredness. They did poorly. Dr. Home believes that the part of the brain where thinking takes place may becomes very tired during waking hours. Sleep may help to repair the brain. "Without any sleep," he emphasizes(强调), "even if you pay closer attention,　you can't do better. "

　　It's important to learn about protecting environment. Here is 5R rule for us:

　　1. Reduce

　　If you want to reduce waste, you should use things wisely. A large number of trees are　being cut down to make paper. If everyone uses a little paper carelessly and throw it out,　soon we would not have anv trees left. Other things are also being wasted.and DeODle don'tknow what to do with the waste in big cities. So it is necessary to reduce the waste.

　　3. Recycle

　　Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and　money. For example, coke cans are sent to a factOry, where they are smashed flat and　melted, and the metal things are made for new coke cans.

　　4. Recover

　　When you buy a box of apples, there may be a few rotten apples, you have two choice: one is to throw the whole apples away, or you could cut off the rotten parts and use the good parts.In this way, you are recovering the eatable parts of food.

　　5. Repair
