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 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.

Soon computers and other machines will be able to remember you by looking at your eyes! The programme works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are. The eye-recognition(眼睛识别) programme is tested in shops and banks in the USA, Britain and Italy.

Scientists are working on other systems, such as knowing you from the shape of your face or hand or even your smell! And machines can already tell who you are from your voice or your fingerprint(指纹). But eye-recognition will replace other ways of finding out who you are. It is better, because your eyes don’t change as you get older, or get dirty like hands or fingers. And even twins have different eyes, so the programme can be up to 94% correct, depending on how good the technology is. In Britain, it was found that 91% of people said that they liked the idea of eye-recognition.

根据短文内容，选择正确答案。

1.Where has the programme for remembering eyes been tested?

A.Banks and factories. B.Banks and shops.

C.Schools and computers. D.Schools and shops.

2.How does the eye-recognition programme work?

A.You look at the machine and type a number. B.You need to speak and then look.

C.The machine looks at your face. D.You look at the machine.

3.Which recognition technology is already in use?

A.Remembering eyes or smell. B.Remembering fingerprints or voices.

C.Remembering faces or voices. D.Remembering hands or faces.

4.What problems could there be with the eye-recognition programme?

A.Some eyes are the same. B.Eyes can change.

C.It is not always correct. D.Eyes can get dirty.

5.What is the advantage of the eye-recognition programme?

A.You needn’t remember a number. B.You needn’t take money with you.

C.You don’t need to look at the machine. D.People think it’s interesting.

Today almost everyone knows computers and the Internet. If I ask you “What is the most important in your life?” maybe you will say “Computers and the Internet.”

The first computer was made in 1946. it was very big but it worked slowly. Today computers are getting smaller and smaller. But they work faster and faster. What can computers do? A writer has said, “People can’t live without computers today.”

The Internet came a little later than computers. It is about twenty-five years later than computers. But now it can be found almost everywhere. We can use it to read books, writer letters, do shopping, play computer games or make friends.

Many students like the Internet very much. They often go into the Internet as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don’t know their real names, ages, and even sex. They are so interested in making the “unreal friends” that they can’t put their hearts into study. Many of them can’t catch up with others on many subjects because of that.

We can use computers and the Internet to learn more about the world. But at the same time, we should remember that not all the things can be done by computers and the Internet.

1. The Internet can not be used for______.

2. When the computer was invented, it was______.

3. The Internet was born in about________.

4.Which of the following is TRUE?

5.What does the writer think of the Internet?
