There are many ways to help improve your health like eating healthy food, taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are, the longer sleep you need. But regardless of(不管)age, some people need to sleep more while for some a few hours is enough.
The problem with sleep is that more and more people in the world are not sleeping enough.
According to the World Health Organization over half the people in the world may be sleep-deprived. Having less sleep not only makes people feel tired but also causes accidents. In the United States alone, sleepy drivers cause at least 100, 000 traffic accidents a year. Also sleep problems can cause medical problems such as high blood pressure.
Why are so many people sleep-deprived? Part of the reasons may be cultural. In the American culture, people put a higher value on work than on sleep. In fact, people who sleep a lot are usually seen as "lazy". Also, you can sometimes hear some people say proudly that they don't have much time to sleep. They only sleep four or five hours a night. It seems that the less you sleep, the more work you'll do.
How do we teach these people to learn the value of sleep? Perhaps they may listen to the advice of Dr. James Maas, an expert(专家)in sleep. He says, "Sleep is like a credit(信用卡)card. When you sleep less, you are only borrowing time. You always have to pay it back. The more hours you don't sleep, the more hours you should sleep to "pay back" the hours on your 'sleep credit card'."
For those who value work more than sleep, they should listen to what a famous person once said. "Don't think you will be doing less work because you sleep during the night. That is a foolish idea which is held by people who have no imagination. You will be able to do more."

Most scientists say animals never feel happy or sad. In fact, they say animals probably don't feel love, anger, hate or other emotions, either.
Scientist Joseph LeDoux studied mice to find out whether animals have emotions. He found that mice feel at least one emotion—fear. He also found the part of the brain that seems to control fear in mice. In humans, that part of the brain controls fear and some other emotions.
A number of scientists say animals have emotions. Some scientists who have studied such animals as dogs, cats, elephants and lions say those animals feel emotions.
Scientist Joyce Poole studies elephants. She has written that pachyderms often show sadness when a relative dies. She says elephants have "deep emotions".
Jane Goodall studies chimpanzees(黑猩猩). She says she has seen them playing and running after one another for fun. Goodall also says they feel sad sometimes. For example, an old chimpanzee died, and one of her sons, Flint, refused to eat food. Flint's brothers and sisters tried to get him to eat, but they failed. Three weeks later, Flint died. Goodall says Flint "died of sadness".
More recently, scientist Marc Bekoff watched an elk(糜鹿)run back and forth through the snow. Bekoff said it was feeling the "joy of life". He said he couldn't prove that animals have feelings, because animals can't talk. But he said animals can communicate feelings in other ways. "I can't prove that an animal is feeling happy or sad, but I can guess how he or she is feeling through body language and facial expressions, "he said.

Fights at school sometimes happen. But how can you keep away from a fight? Here's something you can do.
Be calm. Sometimes, you feel so angry that you really want to teach somebody a lesson. But being angry can't solve problems. Neither can a fight. Instead, it may bring you more problems. In the school, everyone involved(卷入)in a fight will be punished, no matter who started it. There are no winners in a fight.
Shout loudly. If you know someone is coming up behind you to attack, turn toward the person with your hands up in front of your body and loudly say "stop" before walking away. Loud voice can usually make the attacker calm down. If the person doesn't stop, cry for help by calling out the name of a teacher whose office is nearby.
▲ Your friend may ask you to join in a fight. Learn to say no. Helping him fight is not really helpful to him. If you really want to give him a hand, try to ask him to give it up. Also, you can tell him if he gets involved in a fight, he may get hurt and be punished. Then, try to learn why he wants a fight and help him find a right way to deal with the problem.
