     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 1earn

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?
