The internet was set up in the 20th century. At that time computers were big and expensive. Later, the
computer becomes small and cheap. Thanks to (多亏) the internet, the world becomes smaller and smaller.
     A net friend is a man who talks to you online. You first talk to him in a chat room and then begin to know
him well. You never probably (可能) meet them, you have no way of knowing the real world around them.
So you mustn't meet or go out with them.
     QQ is a good way to chat and make friends. Now some young people don't often talk with their parents
or teachers, but they talk a lot with the old friends on QQ, but you must be careful about making net friends,
because you don't know the friends are good or bad on QQ.
