A famous study was done in a school by a professor （教授） from a university. At the start of the school year, the teachers were given the names of five children. They were told that these five were the most excellent students in the class. But the fact was that these students were only average(中等)，and they were not the best students at all. Well, guess what? At the end of the year, all the five average students scored among the highest in the class.

　　What made these average students change so much to become top students？The only difference was the change in their teachers’ attitude(态度). Because the teachers believed that these five kids were the top students，they expected(期望) more from them. And so these five average students began to believe and expect more from themselves. So they worked harder to do as well as they could.

　　Do you know why? If you expect the best from people, they’ll usually want to give you their best. A great leader said, “Treat(对待) a person just how he appears to be on the outside, and you’ll make him even worse. But treat a person like he’s already a success，and you’ll help make him the best he can be.”

　　Like the true story of 7-year-old Johnny, his teacher got so angry with him that one day she said，“Johnny，you’re the naughtiest(最顽皮的) boy in this class. I’m sure you’ll never change.” The next year Johnny had a new teacher. And on the first day of class，she met with Johnny after school and said，“Johnny, I’ve heard a lot about you! But do you know that I don’t believe a word of it.” And every day after that, this new teacher treated Johnny as if he was one of the smartest students even when Johnny did naughty things. Later on, Johnny became a school leader. Because that’s the power of our belief(信任) and attitude(态度) toward children.

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.
