In summary, it would be very difficult to learn if you don't have a teacher. Also you should pay attention to the importance of working together in a class.So I hope every student values this great invention and makes good use of it.

The rapid development of the Internet inChinahas brought us great convenience in our daily life and work. We can send e-mail or even talk to our friends or parents via the Net. We can get whatever we need on line. So some people think we can learn all we need on the Internet.

中国互联网的快速发展给我们的日常生活和工作带来了很大的方便。我们可以通过网络给朋友们发送邮件甚至是和他们交谈。我们从网上获取我们想要的任何东西。因此，有些人认为我们可以从互联网上学到我们需要的所有东西。

But I do not agree with this opinion, because sometimes I find many students play the computer games, or talk about love affairs through the Net, which makesthem fall behind others in study. In my opinion, the Internet should be a good tool for us to communicate with others rather than an invention for fun. What’s more, it will do harm to us instead of good if we spend too much time looking at a computer.

但是，我不同意这个观点，因为有时候我发现很多学生玩电脑游戏或者通过网络谈恋爱，这会使他们在学习上落后于别人。在我看来，互联网应该是我们和别人沟通的好工具，而不是一项娱乐发明。另外，如果我们花太多时间面对电脑的，它会给我们带来害处而不是好处。

In summary, it would be very difficult to learn if you don't have a teacher. Also you should pay attention to the importance of working together in a class.So I hope every student values this great invention and makes good use of it.

总之，如果没有老师，你是很难学会的。此外，你应该注意在一个班级共同努力的重要性。因此，我希望每个同学能够正确对待这一伟大的发明并且好好利用它。
