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 comput
er, 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．

Perhaps you’ve had such experiences like these. Most people have. But most of them haven’t realized that they have a memory problem. Neither do they know a simple but important fact: Memory can be improved. If you just accept that, the following will show you how.
First, relax. If you are over worried about something, you’ll forget it. If you keep telling yourself that your memory is bad, your mind will come t
o believe it and you won’t remember things. When you forget something, don’t follow up with saying like “Oh, my god! I always forget things! ” Such words will have a bad result 
on you and your memory.
But relaxing isn’t enough. To improve your memory, you’ll need to take an active role. Like your body, your memory can be made strong through exercise. Look for opportunities to exercise your memory. For example, if you’re learning a language, try to actively remember a lot of new words.
If you don’t take notice of things actively, you won’t remember them. So, you can make pictures of what you see in your mind every day. For example, don’t just put your keys down! If you want to find them again, make a mind picture of the place where you’re putting them.

Although I didn’t have any interest in being a school bus driver, I became one. Many years later, I was still working on the school bus. There are so many good reasons. Firstly, the talk brought me different kinds of information. I also got to hear all the family secrets of the newcomers. I have a toy bear who was a great comforter(安慰者) for the little ones. The kids got to look after him on the trip to school and he waited patiently for them to get on for the trip home.
Our bus would often pass a place where we could see some alpacas (羊驼) in front of a farm house. Little Michael would cry excitedly from the seat, “Look, Miss! Look at the camels!” He used to put his head out of the bus window. When I warned him that a little insect would come into his nose if he wasn’t careful, he smartly gave up the habit.
I remember a little girl got on the bus one morning 5 years ago and sobbed(抽泣) all the way to school. We arrived at the school gate. As she waited to get down the bus, she threw her arms around my neck and cried that her grandfather had died the night before.
A school bus driver needs to keep one eye on the road and the other on the mirror to watch what the little ones are doing down the back.
Now, it’s important to think how many lives I’ve been responsible(负责的) for, and how many kilometers I’ve driven in order to get my passengers home safely during the 20 years. I’ve enjoy
ed it, but it’s time to rest and park my school bus.
