There are four kinds of demonstration structures: hierarchical, comparative, total score and parallel. Argumentative essay structure refers to the basic structure of argumentative essay, which consists of introduction, theory and conclusion. Generally speaking, the introduction is the beginning, the theory is the theme and the conclusion is the end.

Step-by-step type means that the latter argument is based on the previous argument, and the relationship between before and after is gradually promoted and deepened. In the hierarchical structure, the order of each level and paragraph is closely linked and cannot be changed at will. The advantage of this layout is that it can reflect the author's rigorous logical thinking ability.

Contrast formula refers to the comparison of this part of the argument when expounding and demonstrating it. It is the relationship between positive and negative comparison or related comparison of argumentation content. The specific arrangement is to compare two things or meanings positively and negatively, or to compare one thing or meaning with another. Its advantages are clear layout contrast, clear focus and outstanding arguments.

Sum formula is an argument method that introduces the relationship between general theory and local theory into the argument paragraphs and hierarchical structure. The application of this method can make the content of argument clear and orderly.

Parallelism: in the argumentative essay, the central argument is analyzed in detail, and several sub-arguments are decomposed to jointly explain the central argument of the article. This is juxtaposition.
