As the name implies, a comment is a comment on an argument. State an argument and ask for comments on it. The content of the comment depends on the content of the test questions, which may or may not include: whether the argument is clear in concept definition; Whether the demonstration method is correct; Whether the parameter is valid; Whether the argument is sufficient to support the conclusion; Whether there are stronger arguments to support the conclusion; Whether there are errors or loopholes in reasoning; Whether other conditions are needed for the establishment of the argument; Whether there are other explanations to oppose or weaken the argument, and what amendments can make the argument stronger.

If you really want to write a meaningful summary article, you need the following points:

First, commenting on articles requires some knowledge.

This is very important. It's not impossible to comment on articles. It is essential to pay attention to your favorite fields every day. Only with news can you comment on the topic, so that you can have your own thoughts and opinions on something. But just watching the news is not enough. You should also need some basic writing skills.

Second, writing a composition should be "regular"

This is a written expression. Like writing a composition, the common thinking of writing a review article is written in such a routine (always-divided-always). The general method is to quote or describe something at the beginning (always). (Points): Divide this matter and describe and prove it with various viewpoints, especially your own. (General): That is the final summary of the article, expressing some personal feelings, summaries, conjectures and so on.

Third: Have your own opinions.

I have seen many blogs directly quote a video and put it in their blogs without explanation. Some just said: This is a video I like very much. Let's have a look. Unless you are Lao Xu, no one will care about your preferences. This is my most taboo article. Without your own ideas and opinions, you might as well watch the news broadcast.

Fourth: Write with your heart.

I have nothing to say about the fourth point. I wrote it with care, and everyone will understand it after reading it.
