In these days,Internet has played an important role in our life.In the same way,online course is indispensable for students and teachers.Here I want to write some opinions about online course as follows.

On the one hand,online course enable students and teachers to work more efficiently.For the students,we can learn more courses from the Internet.In addition,we can speed it up if there is some familiar knowledge.As for the teachers,online course is a good way to release them from repeating the same contents.On the other hand,there are some risks in it.A lot of teenagers even lost their thought because of online course.Obviously,it lack of face-to-face communications,which make us can't get a good understanding of the teacher's explain.

All in all,online course,a new teaching method based on Internet has deep influence on us.We should also exchange our views with others when we study online.As far as I am concerned,in this way can we make the better use of it.
