Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries slowly.

　You probably know how to ride a bike safely. Now learn to use a computer safely.

Your eyes

　Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters from the screen. Remember to look away from it sometimes. This gives your eyes a rest.

　When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.

Your hands and wrists (手腕)

　　Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something. 2) Keep your elbows (肘部） at the same height as the keyboard. 3) Stop something and exercise your hands, wrists and fingers in a different way.

Your back

　　Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should all be in front of your eyes. Your forearms（前臂）, wrists, hands and the upper（上部） part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and necks.

　　Some people think only school children do not agree with their parents, however, it is not true. Communication is a problem for parents and children of all ages. If it's hard for you to communicate with your parents, don't worry about it. Here are some advice for you to bridge the generation gap(消除代沟).

　　Don't argue(争辩) with your parents. Don't get to your parents when you are angry. Your parents probably won't agree with your ideas if you are shouting at them. And you can't express yourself well if you are angry. Go someplace to cool off. Make sure you understand why you are unhappy. Then think about what you want to say to your parents. If you don't think you can speak to them at the moment, try writing a letter.

　　Try to reach a compromise(和解). Perhaps you and your parents disagree on something. You can keep your disagreement and try your best to accept each other. Michael's mother didn't agree with him about buying a motorcycle. They argued over it. But they finally came to a compromise. Michael bought the motorcycle, but only drove it on certain days.

　　Of course, your parents might refuse to compromise on something. In these situations, it is especially important to show love and respect(尊敬) to them. Showing respect will keep your relationship strong.

　　Talk about your values(价值观). The values of your parents are probably different from those of your own. Tell your parents what you care about and why. Understanding your values might help them see your purposes in life.

“Four pounds fifty,”says David．
