Surfing the Internet can help open students' eyes and get more knowledge. As a teacher, I encourage my students to use the Internet. In class those students who surf the Internet understand lessons better than the others. Besides, people can use the Internet to write letters or stories and send emails. Many students communicate with their friends online. You can also make friends by chatting on QQ. It is cheaper than calling somebody far away and it's also much quicker. Nearly one third of young people surf the Internet for fun. They like to listen to music, watch films, and go to their favourite stars' websites. But can the Internet cause problems? Some of my students who used to study well at school are now failing exams(考试不及格)，because they spend a lot of time playing computer games.
