     Your friends might be in Australia or may be just down the road, but they are all just a few clicks

(点击) away. Life has changed for millions of young people across the world who now make friends

online. Whether you use chat-rooms, QQ, MSN or ICQ, you are a member of this group.

     "I don't often talk with my parents or grand-parents, but I talk a lot with my old friends on QQ," said

Fox's Shadow, the online name used by a girl student in China. "Most of my classmates use QQ after

school."

     QQ is the biggest messaging service in China. A recorder from Tencent, the company which

developed QQ, shows that 4 million people used it one Saturday night in October. And probably Fox's

Shadow was one of them. "I log in(登陆) on Friday nights, and Saturdays when I feel everything around

me boring. I usually spend about ten hours chatting on-line every week," she said. "But I never talk with

strangers, especially boys or men."

     Even though she likes chatting, she is careful about making friends with strangers online. "You don't

know who you're talking to. You should always be careful about whom you believe in online." Many

people would like to meet offline when they feel they have got to know someone very well. Fox's

Shadow once met one of her online friends face to face. It was a girl who was a football fan like herself

and they went to a football match together.

     A 16-year-old Beijing boy, named Bart Simon online, dislikes QQ uses. "I used to chat on QQ, but

I found that most people were talking about foolish things," he said. Now he chats online in English, using MSN. "I only chat online because I've got friends in Japan, the US and Singapore," he said. "I want to

learn more about foreign cultures." But he spends little time chatting on QQ as he sees it as a waste of

time and money.

     "If you are really addicted to(沉溺于) it, sometimes you can't give your mind to your lessons," he

said. "And friends in your real life are always more important than those so-called friends you meet

online."
