Nowadays the Internet has become part of our daily life. Some students even think that computers can give us lessons instead of teachers .I don't agree with this opinion. In my opinion, we can't have lessons without teachers because teachers can help us whenever we meet with difficulties or questions. What's more, it's very important to work together as a class.
There are some other disadvantages besides these.Firstly, it will be harmful to our eyes if we look at a computer for a long time. Secondly, it takes us so much time , money and energy. If we spent too long time playing computer games and got addicted to it , it would be very difficult to get out of it. What's worse, we may have access to the scenes of violence and sex
