With the devolopment of internet ,we can also make friends on line. QQ and friends-making websites facilitate our communications with strangers.
　　Some people think that people can more freely express their feelings and opinions through chatting on line. we canalso make friends with people who have different cultural background and personal opinions ,which will surely widen our eyes and make us more knowledgeable. Connecting with people especially from English-speaking countries through Internet can also improves our English level. While some other people think differently.Only a few people have succeeded in getting a real good friend in this way .Most of people have been cheated .Some people have committed crimes with the friends on line .What's more ,surfing online is just wasting time .It will not only have a bad effect on study but also do harm to our health.
　　Personally ,I think it's a pretty cool thing to have several foreign friends, but we should learn to use computers in our own right ways. The Internet doesn’t have no responsibility, it depends on the way we use it.
