The structure of argumentative writing is: total score, parallelism, progression and contrast. The basic structure is 1, asking questions (introduction), analyzing problems (theory) and solving problems (conclusion).

It can be divided into two categories.

A. vertical style: discuss the structure step by step.

Example 1. "Layer by layer deepening" type, first put forward the argument, then demonstrate it from the opposite side, and then further discuss it from the front.

Example 2. "start recording, turn around" style: break the topic at the beginning and lead to discussion; Then take the lead and explain the problems discussed; "Turn" is a double proof argument from all angles; In the final analysis, it is "combination."

B. horizontal style: parallel expanded discourse structure

For example:

There is a kind of "general-sub-theory-general" style, which first puts forward the argument, then expounds it from several aspects and finally summarizes it;

There is a style of "general theory-divided theory", which first puts forward arguments and then demonstrates them from several aspects.

There is a style of "divided theory-general theory". The things to be discussed are always analyzed in several aspects, and then a comprehensive conclusion is drawn.

In a word, to analyze the structure of an argumentative essay, we should first understand the internal relationship between the levels of paragraphs in the article, and also pay attention to the transitional paragraphs, transitional sentences and transitional words that serve as a link between the preceding and the following.

The linguistic features of argumentative writing are: ① accuracy and strictness. ② Generality and conciseness. (3) Use rhetoric to express its vivid, vivid and emotional words.
