Inernet has been an important part in our life.With the help of Inernet we can develop the effective of our study or job.For example ,we can learn more knowledge about the world from the Inernet.And as the youngs in 21st centery,the skill of using the Internet has been the most necessary point for us.But there are risks in it.A lot of youngners lost themselves in the data world and can not catch up with others in study.They'd like to be the best in the games instead of in hard-working.In my own point,I think Internet has more advantages than disadvantages.People should make the most use of it so that it can been useful not harmful.
