With the development of Internet, distance learning is gaining more and more popularity among us students. Many a student is addicted with online lessons. Is distance learning really benefit to us students?

In my opinion, distance learning has some advantages. As it is known to us, it is vivid and flexible because of lots of video materials and adjustable schedules. Therefore, its disadvantages should be equally paying attention to. Firstly, it isn’t suitable for students who prefers direct communication with teachers. What s worse, studying online too long greatly does harm to student’s eyes.

So what I want to express finally is that our students should weigh the advantages and disadvantages and use distance learning proper.
