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

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(反射) on the screen. If the windows 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 times, follow these three rules: 1) Rest your wrists on something. 2) Keep your elbows at the same height as the keyboard. 3) Stop sometimes 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 a 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 be in front of your eyes. Your forearms(前臂), wrists and hands should all be parallel to(与......平衡) the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and neck.

Enjoy your computer, but use it safely.

Once a circle lost a piece of its own. The circle wanted to be whole, so it went around looking for its missing piece. But because it was not complete, it could only roll (滚动) very slowly. It enjoyed the flowers and the sunshine along the way. It talked with worms(蠕虫). It found lots of different pieces, but none of them was fit. So it left them all by the side of the road and kept on looking for the missing piece. Then one day the circle found a piece that fit perfectly (完美). The circle put the missing piece into itself. It could be whole with nothing missing. It was so happy and began to roll. As it was a perfect circle, it could roll very fast, too fast to see flowers or talk to worms. It realized how different the world was when it rolled so quickly. It felt so sad that it stopped, left its found piece by the side of the road and rolled away slowly.

A man who has everything is a poor man in some ways. He will never have hopes, dreams or something better. He will never know someone loves him or someone is giving him something he has always wanted or never had. We couldn't be perfect, but we must be brave enough to love, strong enough to forgive (原谅), kind enough to share happiness with others and clever enough to know there is enough love around us, and then we can always have a wonderful time in our lives.
