Computers can injure (伤害) 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 happen 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 more than 50 centimeters from the screen. Don’t forget 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) as high 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 the wrong way, you can injure your back or your neck. So you shouldn’t bend your back when you sit. The top part of the screen should 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 half an hour and exercise your arms, legs and neck.
Enjoy your computer, but use it safely.

My children are1. up fast. My daughter is 16 and my boy is already in junior high school. As they get bigger our house seems to get2. . So we want to sell some of our things in a yard sale and give the money to a3. home.
We have already cleared out a lot of things from our bedrooms. We have 4. to each sell five things that we no longer use. My son was quite 5. at first. Although he has not played with his old toys for a long time, he still wanted to keep them. For example, he has owned a train and railway set since his6. birthday, and he played with it almost every week until he was about seven. And he did not want to lose his toy monkey, either.
He 7. next to the monkey every night when he was a child. My daughter was more understanding, although she also felt sad to part with8. toys.
As for 9. , I did not want to give up my football shirts, but, to be10. , I have not played for a while now. I am getting older, too!
