题型:完形填空
As we all know, the Internet has become part of teenagers(青少年)       . A new reporter on 3,375 students aged from 10 to 18 in seven Chinese cities found that 38 percent of them used the Internet very       .
Most of them get useful information and use the Internet to help in their studies, but some are not using it in a        way .Many are playing online games too much.       even visit websites (网站)they should not look at. A teacher from Yucai Middle School says that bad things can happen if young people       too much time on the Internet. She had a student who used to be (曾经)good at school.     then he started visiting unhealthy websites. He went mad(变得疯狂),cheated(欺骗)a girl and was taken away by the police.
In order to help young people use the Internet       a good way, a textbook on good Internet behavior(行为) has started to be used in some middle schools this term. The book uses real examples to       students about good ways of using the Internet. The book gives useful advice such as to read news or to find helpful     to study. Teachers and parents all think the book is very good.
The book will be a guide (向导) for teens to use the Internet. We believe it will keep students away from bad websites, and teach students       to be a good person in the online world.
