The Internet has become part of teenagers’(十几岁的) life. 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. She believes it will keep students away from bad sites.

Now many people like to keep dogs as their pets. But how did dogs become humans’ close friends
In some places of Europe (欧洲), about 10,000 years ago, some wild (野生的) dogs often came to human’s houses to find food. The wild dogs looked different from the ones today. They looked like wolves (狼). At first, they felt ① frightened. They always stood and looked for a short time. Then they got the food and ran away. Sometimes the young dogs couldn’t run fast and people caught them. People trained them and the young dogs grew up with the help of people. Slowly, the wild dogs became home dogs. They could make home safe when people were away. They helped people hunt (狩猎). They helped people keep warm on cold nights. ② Sometimes, they could smell and hear danger before people could. In some cold places, they helped people pull (拉) things people need.
Now there are more than 400 different kinds of dogs in the world. And they look different from each other. The number and kind are growing all the time. Today, some people mainly (主要地) regard dogs as pets. In fact, dogs are really our close friends. We should protect them from being killed.
