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.

What will you do if weight keeps going up? Here are ideas to help you stay healthy:
Don’t sit around
Stay active. Try to exercise 30 to 60 minutes every day. Your exercise doesn’t have to be hard. Start small. Take the stairs instead of the elevator(电梯). Walk or ride a bike to places such as school or a friend’s house. Help your mum with housework, such as cleaning windows or the bathroom. It all burns fat. Make changes from time to time so you don’t get bored: Try running, biking, skating. There are many choices. Don’t spend long hours watching TV or playing video games. Even reading a book burns more fat.
Eat healthy
Truly different kinds of food and get enough fruits and vegetables each day. Drink water and low fat milk instead of soft drinks like Cola. Stay away from fast food. Eat when you are hungry, not when you are bored or because you can’t think of anything else to. Don’t eat meals or snacks while watching TV because you’ll probably end up eating more than you need. Some worry so much about their weight that they don’t eat breakfast. This is a bad idea. Teenagers need enough food. If not, you won’t get the nutrients you need to grow normally.
Don’t rush to go on a diet
Even if you are a little heavier than your fiends, you still may be normal. Remember to talk to doctors and your parents before you decide to lose weight.

A man came home from work late, tired, to find his 5-year-old son waiting for him at the door.

“Daddy, how much money do you make an hour?”

“If you must know, I make $20 an hour,”

“Oh,” the little boy replied, with his head down. He thought for a moment, looked up and said, “Daddy, could you lend me $10?”

The father was furious, “If you asked for the money to buy a toy or some other rubbish, then go straight to your room and think about why you are being so selfish（自私的）!”

The little boy quietly went to his room and shut the door. After about an hour or so, the father calmed down, and started to think, “Maybe he really needs to buy something and he didn’t really ask for money very often.” So he went to the little boy’s room.

“Sorry! Maybe I was too hard on you just now.” said the man, “Here’s $10.”

“Oh, thank you, Daddy!” he said happily. Then, the boy took out some coins. When the father found that the boy already had money, he got angry again.

“Why do you want more money since you already have some?” The father shouted angrily.

“Because I didn’t have enough, but now I do.” the little boy replied, “Daddy, I have $20 now. Can I buy an hour of your time? Please come home early tomorrow. I would like to have dinner with you.”
