Now, China has the second largest number of Internet users in the world after the United States.
Many of Chinese Internet users are teenagers. They spend about 13 hours every week online. On the
Internet, students can find out almost anything. Surfing the Internet（网上冲浪）can help them with their
homework and learn a lot of knowledge.
People can use the Internet to write letters, stories and to send emails. Many teenagers keep in touch
with their friends online. They can also make new friends through QQ or ICQ.
Some of the students surf the Internet just for fun. They like to listen to music, watch films, and go to
their favourite stars' websites.
But some parents always think that the Internet takes young people away from study. "They spend too
much time playing computer games and most games are about killing and fighting. It's too dangerous. And
there are some dirty things on the Internet, "says the mother of a 13-year-old boy.
