Now, China has more than 68 million Internet users, according to the China Internet Network Information
Centre. This is the second highest number of users in the world after the United States. Today, 44% of
Chinese "netizens (网民)" are teenagers."They spend about 13 hours every week online," said Qian Hulin, an
Internet expert.
The main reasons why teenagers surf the Web 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 Web can help
students with their homework and widen 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 information than the others," she
said.
In addition, people can use the Internet to write letters or stories and send emails. Many teens keep in
touch with their friends online. It is cheaper than phoning somebody far away and also much quicker.
