1. Vertical structure mode

According to the introduction (introduction, introduction), this theory (text) and conclusion, the material is organized into three parts, which are called longitudinal structure. Generally, it is arranged in the logical order of asking questions, analyzing problems and solving problems. Also known as "three-stage structure".

2. Parallel structure

Around the central argument, from different angles to demonstrate, forming a number of sub-arguments, a number of sub-arguments constitute a parallel relationship, * * * and the central argument of the argument, which is the parallel structure of argumentative papers.

3. Progressive structure

When expounding the central argument, the relationship between all levels and paragraphs is interlocking and deepening step by step. The former part is the basis of the latter part, and finally draws the conclusion of the article.

4. Contrast structure

This is a structural way that combines positive and negative views, examples and backchat, forming a strong contrast, making two different things clearer in comparison, thus highlighting positive arguments and propositions more effectively.

In argumentative writing, the above structural models are often used alternately, and generally one structural model is the main one, supplemented by other models. In this way, the style of writing can be varied and the articles will not be chaotic. ?
