Nowadays more and more schools and students focus on online education. Of course， online education is shaping up as the hottest issue. As we all know， everything has two sides. On the one hand，online education not only can save time so that we can do more other things， but also can be convenient for our daily life and study. Moreover， after class we can find the videos which we did not understand and then study again. On the other hand， online education will increase in the face of the computer time which will be harmful to our health， especially it will lend to vision loss. Online education will reduce between students and teachers and students exchanges. Besides， it will make students become lazy more and more. Most of all， online education is short of the learning atmosphere. In my opinion， I prefer online education because it can help us save a lot of time to solve our other things. We should reduce the face of the computer time to maintain our health. Above all， it is convenient for our study indeed. So I support online education.
