现在，中国有一亿六千多万网民，其中66%是青少年。你知道人们上网做什么吗？你能够想象得到没有网络的世界会是什么样子吗？
Can you imagine a world without the Internet? It's surprising to think about it.
Now，China has more than 162 million Internet users，according to the China Internet Network Information Centre. This is the second largest number of users in the world after the United States. Today，66% of Chinese “netizens(网民)” are teenagers. “They spend about thirteen hours every week online，” said Qian Hulin，an Internet expert. Doctor Song in Beijing Xuanwu Hospital said about 14% of Chinese netizens who are teens often lasted over ten hours to play online games.
The main reasons why teenagers surf the Net are to search for information，to communicate with others and to have fun. On the Internet，teenagers can find out almost anything. And surfing the Net can help students with their homework and widen(扩大) their knowledge.
Li Dong，a teacher at No.41 Middle School in Shijiazhuang，likes her students to use the Internet. “When we talk in class，students who surf the Net usually know more background(背景) information than the others，” she said.
In addition，people can use the Internet to write letters or stories，send emails and chat. Many teens keep in touch with their friends online. It is cheaper than phoning somebody far away and also much quicker.
