A new report on 3,375 students aged from 10 to 18 in seven Chinese cities found that 38 percent of them believe they use the Internet often.While most of them get useful information and use the Internet to help in their studies, some are not using it in a good way. Many are playing online games too much. A few even visit websites(网址) they should not look at. Hong Ying, a teacher from Beijing Yinghua Middle School warns(警告) that bad things can happen if young people spend too much time on the Internet. She had a student who used to be good at school. But then he started visiting unhealthy websites. He went mad, cheated(欺骗) a girl and was taken away by the police.In order to help young people use the Internet in a good way, a textbook on good Internet behavior(行为) has started to be used in some Shanghai middle schools this term. The book uses real examples to teach students about good ways of using the Internet. The book gives useful advice such as to read news or to find helpful information to study. Teachers and parents all think the book is a very good idea.Hong said the book will be a guide for teens to use the Internet.
