Computers can injure (傷害) 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) at the same height (高度)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.

Some time ago, an old businessman had a large store in Boston. He wanted a boy to work for him, and he put an advertisement in the newspapers. The next morning, many boys came to the old man’s office, asking for the job.

There was a post by his desk, and there was a nail in it. He took a 2walking stick and said, “Everyone has three chances. If anyone can hit that nail on the head with this stick more than once, I will give him the job.”

The boys thought it was very easy. They all tried, but nobody could make it. So the old man said, “I’m sorry I can’t take any of you,” and they left.

He kept the advertisement in the papers, and the next morning many more boys came, and among them he saw a thin boy who had been there the day before. The boy hit the nail successfully for three times. The old man felt surprised and asked how he did that.

“Yes,” said the boy, “I failed yesterday, but I thought that if I kept on trying a while, I could do it. So I went home and practiced hitting a nail with a stick till I could do it, and I got up very early this morning, and tried again.”

The old man said, “You are the boy for me,” and gave him the job. Whatever the boy had to do, he tried to do his best. It was not very long before he became the best clerk in the store.

How to beat sadness

We all have days when we are down, tired and unhappy. That’s OK. You need days like this, or how would you know you are happy? You’ll enjoy your good days even more when you have a few bad days. Even if sadness is a part of life, let’s try to make it small. Here are a few simple ways to help you feel better when you are feeling sad.

1. Stand up straight and this helps your energy flow(流動). When your energy is flowing freely, you can flow too.

2. Smile! It’s easy to do and have good results. This way can not only leave you in a good mood but also bring others a good mood.

3. Listen to music. It can be your favourite music. Some kinds of music work better than others, so try and find out what kind of music works the best for you.

4. Take some “me” time. You can find pleasure in reading a book, watching a sunrise or having a hot bath, or something like that.

5. Exercise. Even something as simple as taking a walk will get your blood flowing. It is a great way to clear your mind of anything that makes you sad.

These ways will cheer you up when you are down, but don’t just use them when you are sad. Try and practice them every day to make them a habit. You will be surprised to learn that these simple ways will keep your sadness away. But if you are in a deep depression(沮喪), go to see a doctor.
