Do you know why you sleep? You may think it"s because you"re tired. Or perhaps you"ve been told sleep is good for you. Yet no one knows exactly why or how people sleep. Until the early 1950s, most scientists thought the body and brain rested during sleep. Then a scientist watched people sleep. He noticed that during periods of between 5 and 30 minutes, sleepers" eyes made rapid movements, as if they were watching something. He called these periods REM (Rapid Eye Movement) sleep. He called periods when sleeper"s eyes did not move non-REM sleep. Whenever the scientist woke people during REM sleep, they were having vivid dreams. Measurements showed that sleepers" pulses (脉搏) went up quickly during REM sleep. Their breathing, heartbeat, and the blood going to the brain also increased. Far from being a time of rest, sleep is a time when the body is hard at work. Scientists still don"t know the reason for this. Some believe REM sleep makes learning easier. Babies spend a lot of time on REM sleep. Because of this, some scientists believe that REM sleep helps the brain grow. Others think REM sleep is a time for the brain to empty the day"s garbage. One thing all the scientists agree on is that sleep is necessary. Without enough sleep, people make mistakes. Most car accidents happen during the early morning hours, when people are sleepiest. | |

Japan is one of the cleanest countries in the world. What are its secrets? In Japan, people have to pay for their garbage. If they have a lot, or their garbage is difficult to treat, they have to pay more. They also have to pay for things they no longer need, like old TVs and fridges. This makes people think before they throw away. There are few garbage cans in Japanese streets. People take their garbage home and sort through it carefully. They also have different ways of treating different kinds of garbage. People turn old chopsticks into paper. They burn some garbage to make fertilizer (肥料). People even use garbage to make more land area. Japan has set a good example to the rest of the world. If people in every country did the same, we would be able to do something about our environmental problem. What can we do to help the environment? Here are some ideas. ·Reduce! Check it out. Buy products with less packaging (包装). Buy less and create less garbage. We shouldn"t buy things we don"t need. ·Reuse! Be creative and make use of garbage.

Dreams are expressions of thoughts, feelings and events that pass through our mind while we are sleeping. Everybody dreams. But only some people remember their dreams. Our dreams often include all the senses-smells, sounds, sights, tastes and things we touch. We dream in colour. Sometimes we dream the same dream over and over again. These repeated dreams are often unpleasant. They may even be nightmares-bad dreams that frighten us. Early in the twentieth century, two famous scientists developed their personal ideas about dreams. Austrian psychiatrist Sigmund Freud published (出版) a book called "The Interpretation (诠释) of Dreams" in 1900. Freud believed people often dream about things they want but can"t have. These dreams often have something to do with sex and aggression (侵犯行为). Swiss psychiatrist Carl Jung worked closely with Freud for several years, but he believed dreams could help people grow and understand themselves. He believed dreams provide solutions (解决办法) to problems we face when we are awake. He didn"t believe dreams hide our feelings about sex or aggression. Today we know more about the science of dreaming because researchers can take pictures of people"s brains while they are sleeping. Other researchers are studying how dreaming helps our bodies work with problems and very sad emotions. Robert Stick gold is a professor of psychiatry at Harvard University in Massachusetts. Doctor Stick gold says that when we dream, the brain is trying to make sense of the world. He does not agree with Sigmund Freud that dreaming is the way we express our hidden feelings and desire (愿望). Scientists believe it is important to keep researching dreams. Doctor Stick gold says it has been more than one hundred years since Sigmund Freud published his important book about dreaming. Yet there is still no agreement on exactly how the brain works when we are dreaming or why we dream. | |
