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 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, wrists, hands and the upper 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.
Enjoy your computer, but use it safely.

Do you know how to play a game called “Musical Chairs”? It is easy to play and most people enjoy it. All you need are some chairs, some people and some way of making music. You may use a piano or any other musical instrument, if someone can play it. You may use a tape recorder. You can even use a radio.
Put the chairs in a line. The chairs may be put in twos, back to back. A better way is to have the chairs in one row with each chair facing in the opposite direction to the chair next to it.
The game is easy. When the music starts, the players walk round the chairs. Everyone goes in the same direction, of course, they should walk in time to the music. If the music is fast they should walk quickly. If the music is slow, they should walk slowly.
The person playing music cannot see the people in the game. When the music stops, the players try to sit on the chairs. If a person cannot find a chair to sit on, he drops out. Then, before the music starts again, one chair must be taken away. When the music stops again, one more player will be out.
