I think that taking classes online has many advantages. First of all, the class environment is much more pleasant and relaxed. Compared with when we kept silent when we had a break, we are now more talkative. (not sure what this means) The teacher not only chats with us but also plays music and video for us. Also, we can playback the class whenever we want to. It is a good way to digest the information and improve our learning. Finally, we save a lot of trivial time, such as walking to the classroom, eating in the cafeteria, and so on. However, every coin has two sides, and online courses are not an exception. Its disadvantages are obvious. For one thing, some students who are not disciplined would not take classes seriously because teachers can’t see us through the computer, and the students can play video games while taking the class without shame. Therefore, online classes cause polarization between good and bad students: Self-disciplined students can benefit from the online learning environment, while bad students will suffer. In addition, after a long time watching e-books and the computer, everyone feels tired and suffer from sore eyes. To some extent, online classes harm our health.

By comparison, break times are much more chatty now. We had been quiet during breaks but now there is conversation. The teacher not only chats with us but also plays music and videos. We can learn by using the play back feature at our convenience. Finally we save a lot of travel time. There is no time spent walking to the classroom or to the canteen. Every coin has two sides though and the online listening of a course is no exception to this rule. Some students may even play a video game during class and fell no shame about this action. ...everyone feels tired and may get sore eyes. I hope this helps. S.
