Internet is now coming into our life. It brings us not only a lot of convenience ，happiness but also troubles. Some students use Internet as a too to study. They look up the meanings of the words， a translated form of a sentence，the background of an event or a story ，the information of a company or a famous person，etc.
They also read news or send e-mails through it. Internet helps them learn more and study well.
On the other hand，some students play games，chat with friends ，see the pictures or films even the unhealthy ones on the Internet the whole day. They are not interested in their subjects. It's very dangerous for them!
The Internet's advantages and disadvantages are shown clearly to us. I think we should make good use of it and stay away from the unhealthy websites.
互联网正在融入我们的生活。它不仅给我们带来了很多便利，开心同时也带来了麻烦。一些学生使用互联网来学习。他们看了这些单词的意思，翻译成一个句子，一个事件或故事的背景，一个公司或著名人物的信息，等等。
他们也看新闻或通过它发送电子邮件。互联网帮助他们学习更多更好。
另一方面，一些学生一整天都在网上玩游戏，与朋友聊天，看不健康的照片或电影。他们没对他们的学习感兴趣。这对他们来说很危险！
我们都很清楚互联网的优势和劣势。我认为我们应该好好利用它，远离不健康的网站。
