We are already familiar with computers-computers work for us at home, in offices and in factories. But it is also true that many children today are using computers at schools before they can write. What does this mean for the future? Are these children lucky or not?
Many people who do not know about computers think of them as machines that children play with. They worry that children do not learn from experience but just from pressing a button and that this is not good for them. They think that children are growing not knowing about the real world.
But people who understand more about computers say that computers can be very good for children. A computer can help them to learn about the real world more quickly, to learn what they want to learn and think for themselves. And for the future, don't we need people who can think clearly, who know how to get information quickly and use it well? What do you think?

Light travels at a speed which is about a million times faster than the speed of sound. You can get some idea of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke from his gun before the sound reaches your ears.
This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light that you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km. per minute. In some cases, the light from one of tonight's stars had started on its journey to you before you were born.
Thus, if we want to be honest, we can't say, "The stars are shining tonight." We have to say instead, "The stars look pretty. They were shining four years ago, but their light has only just reached the earth."

A friend of mine named Paul received an expensive car from his brother as a Christmas present. On Christmas Eve when Paul came out of his office, a street urchin(顽童) was walking around the shining car. "Is this your car, sir?" he asked.
Paul answered, "Yes, my brother gave it to me for Christmas." The boy was surprised. "You mean your brother gave it to you and it did cost you nothing? Sir, I wish…" He hesitated(犹豫). Paul thought of course he knew what the boy wanted, but what the boy said surprised him greatly. "I wish," the boy went on, "that I could be a brother like that." Paul looked at the boy in surprise, and then he said again, "Would you like to take a ride in my car?" "Oh yes, I'd love to," the boy answered.
After a short ride, the boy turned and with his eyes shining, said, "Sir, would you mind driving in front of my house?"
Paul smiled a little. He thought he knew what the boy wanted. He wanted to show his neighbors that he could ride home in a big car. But Paul was wrong again. "Will you stop where those two steps are?" the boy asked.
He ran up to the steps. Then in a short while Paul heard him coming back, but he was not coming fast. He was carrying his little crippled(残疾的) brother. He sat down on the step and pointed to the car.
"There he is, Buddy, just like I told you upstairs. His brother gave it to him for Christmas and it didn't cost him a cent. And some day I'm going to give you one just like it…then you can see for yourself all the nice things in the Christmas
windows that I've been trying to tell you about."

"I sometimes get up at three or four in the morning and I surf the net."
"I often check my e-mail forty times a day."
"I often spend more than three hours during one time on the net."
"I spend more time in chat rooms(聊天室) than with my 'real-life' friends."
Do you know any people like these? They are part of a new addiction(瘾) called Internet addiction. Internet addicts spend at least thirty to forty hours online every week. The use of the Internet can be an addiction like drug(毒品) use. People lose control(控制) of the time they spend on the Internet
For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he was surfing the net for several days straight.
