The Internet has become part of teenage life. There’s a report on 3,375 students aged from 10 to 18 in seven Chinese cities. It says 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 they should not look at. Bad things can happen if young people spend too much time on the Internet.
In order to help young people use the Internet in a good way, a textbook on good Internet behavior has started to be used in some Shanghai middle schools this term. It uses real examples to teach students all about good ways of using the Internet. It gives useful advice such as it’s good to read news or find helpful information to study. Some students also make online friends. But if you are meeting a friend offline, let your parents know.
