In the era of rapid development of information technology, the Internet plays an important role in society. Some people think that with the Internet, we can easily get the information we need and improve the efficiency of learning and work. But some people think that the Internet has a bad effect on the growth of teenagers. Teenagers can't resist the temptation of the Internet, even some indulge in the Internet, and finally deviate from the track of learning. In my opinion, we should pay more attention to and give full play to the advantages of the Internet. At the same time, we should actively guide young people to use the network, so that the network becomes a tool for the healthy development of young people.
