Argument is a sentence that correctly and clearly expounds the author's point of view, and it is the soul and commander of an article. Any article has only one central argument, and generally there can be sub-arguments.

The argument should be correct, clear and general, and the complete judgment sentence should never be ambiguous.

(1) correctness: the persuasiveness of the argument is rooted in the correct reflection of objective things, which in turn depends on whether the author's position, viewpoint, attitude and method are correct. If the argument itself is incorrect or even absurd, no amount of arguments can convince people. Therefore, the correctness of the argument is the minimum requirement of the paper.

2 Significantness: What is for and what is against should be very clear, and it must not be ambiguous or ambiguous.

Novelty: the argument should be as novel and profound as possible, which can transcend other people's views. It's not repeating other people's platitudes, nor is it irrelevant and general. It should be as unique and novel as possible.

An argument generally has four positions: the title, the beginning, the middle of the article and the end. But it is more often at the beginning of the article, and so is the paragraph argument. When similar statements appear at the beginning and the end, the starting argument and the ending echo argument.

The arguments of some papers are expressed in clear sentences, and we just need to find them out; Others are not directly expressed in clear sentences and need to be refined and summarized by readers themselves. The summarized sentence should not contain rhetorical devices.
