标题 Is opening the blog good or bad for middle school students?
Nowadays, it is a common phenomenon that more and more high school students open their blogs on the Internet. But opening blogs has both many advantages and disadvantages.A blog can be a window that shows the owner to others. If the owner is shy,it is easier for the owner to talk with others.It can also be helpful to the owner to be relaxed. It can also improve our ability of writing articles.
However,every coin has its two sides. Sometimes,it has a bad effect on their studies.
In my opinion,it is good for us to open our blogs,but we shouldn't spend too much time on it ,it is not worth doing that. Our main mission is to learn more knowledge to pass the exams.
