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.
 Enjoy your computer, but use it safely.

In Britain you’re allowed to drive a car when you’re seventeen. You have to get a special two-year driving license before you can start. When you’re learning, someone with a full license always has to be in the car with you because you aren’t allowed to drive the car on the road alone. You don’t have to go to a driving school --- a friend can teach you. The person with you isn’t allowed to take money for the lesson unless he’s got a teacher’s license.

Before you’re allowed to have a full license, you have to take a driving test. You can take a test in your own car, but it has to be fit for the road. In the test you have to drive round for about half an hour and then answer a few questions. If you don’t pass the test, you’re allowed to take it again a few weeks later if you want to. In 1970 a woman passed her fortieth test after 212 driving lessons! When you’ve passed your test, you don’t have to take it again, and you’re allowed to go on driving as long as you like. Britain’s oldest driver was a man who drove in 1974 at the age of 100.

Before 1904 everyone was allowed to drive, even children. Then from 1904 car drivers had to have a license. But they didn’t have to take a test until 1935. On the early days of car driving, before 1878, cars weren’t allowed to go faster than four miles an hour, and someone had to lead the car with a red flag.
