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.

A Talking Fish

One afternoon last summer, Mr. Stow went to a fishman to buy fish for his supper, because a friend of his would come to have supper with him that evening.

It was hot, and most of the fish were not so good, but the fishman said, “Sir, all of my fish are good and fresh. Would you like some?” Mr. Stow held one fish up to his nose and smelled it. “Why do you smell that fish? Do you think it bad?” asked the fishman. “No, I didn’t smell it.” “Then what did you do with your face so close to the fish?” asked the fishman. “I didn’t smell the fish, I only talked to it,” said Mr. Stow. “What did the fish say to you?” “He said he didn’t know the latest news of the river , because he was out of the river for more than a week.”

When I was ten, my sisters and I were amazed at our neighbor’s Christmas tree. We returned home from their house and decided that we must have one of our own. In our house we never had enough money for a Christmas tree.
In fact, we insisted so much that my father had no choice but to agree. “Yes!” he finally said.“This year we will have a Christmas tree.” Our mouths dropped open at the thought of having our own tree. Then Dad said,“I’ll do it myself.”
We followed him around the house as he gathered up the materials he would need, We all sat close to him, carefully watching everything he did. He passed the thread around the first nail on the corner of a box, then back down to the second nail on the box, and up again to the nail, until right there before our eyes a green Christmas tree began to take shape. He carefully did the same with all of the 50 nails in the box and when he had finished, he said,“Now you can decorate it.”
I don’t remember where the decorations came from, but they were red and small and to us they just looked so beautiful and perfect for our tree. When we finished decorating it, we proudly invited all our friends over to see our Christmas tree. We were so happy, not only because it looked so pretty, but because my father had made it himself. It truly was the most beautiful Christmas tree we had ever seen.
Years later, things got better and Dad was able to buy a proper Christmas tree which we would happily decorate. However, my sisters and I will never forget the night when we got our first Christmas tree.
