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. Its very dangerous for them!
The Internets advantages and disadvantages are shown clearly to us. I think we should make good use of it and stay away from the unhealthy websites.
