We summarize the basic model of standardizing argumentative writing as "five paragraphs and three theories", "three points" or "five paragraphs and three theories+1". "Five paragraphs" means that the article is written in five paragraphs (or more than five paragraphs, but still five parts); "Three Theories" not only refers to the introduction, theory and conclusion of the full text, but also refers to three sub-arguments separated by paragraphs, and each sub-argument is divided into three parts: the beginning, the expansion and the end. This feature of this part is also called "subject dichotomy". "+1" means that a "of course" paragraph can be added after the three theories of subject.

The first paragraph: Introduction. Introduce topics or arguments for life phenomena and composition materials; Or for the topic, on the basis of introducing the meaning of the topic, the argument is drawn. The summary of life phenomena and composition materials here should be concise and to the point, highlighting the main points. At the same time, summarize life phenomena and materials, have turning sentences, and then lead to arguments. Transition generally has three directions: summing up the materials and analyzing them clearly, and drawing arguments from the front; Negative analysis of summary materials leads to negative arguments; After analyzing the materials, a new point of view is obtained from another angle.

The middle three paragraphs: This theory is the main body of the full text. Firstly, several sub-arguments, usually three, are established around the central argument. There are generally three methods. The first is to decompose the central argument or topic and form a total score relationship. Second, multi-level and multi-sided design problems make the central argument concrete and three-dimensional, generally from the perspective of conceptual connotation, conditions and reasons, or through assumptions. The third is to design the problem layer by layer, or to determine the argument around the three questions of "what", "why" and "how", or to determine the argument from the time sequence or according to the cognitive process of people.

The sub-argument is established, and the paragraphs of the main argument are led out by the sub-argument. Each paragraph should include three levels of discussion: at the beginning, it puts forward the argument of this paragraph (or a topic from a certain angle), which is called "the central sentence at the beginning of the paragraph"; The expansion part provides case arguments or reason arguments around the central sentence; The last part analyzes the argument and draws a conclusion. A three-part discussion section is called a "complete section".

"Of course" paragraph: Start with "of course", or discuss the other side of the argument, or discriminate the connotation differences of seemingly similar concepts, so as to make the full text dialectical. This paragraph is dispensable, depending on the central argument and discussion; Keep the text short, just two or three sentences.

Concluding paragraph: conclusion. Or sum up the above and highlight the central argument; Or hope, inspire and inspire people; Or issue a call, express sighs, and infect readers.

The model structure of "five paragraphs and three theories";

Introduction: or cut to the chase, explain the concept and put forward the argument; Or summarize phenomena and facts to lead to topics; Or quote the views of predecessors, others and materials, thus leading to your own views.

Discussion paragraph 1: argument 1+ discussion (cause and effect or case)+conclusion (complete paragraph, positive)

Discussion paragraph 2: argument 2+ discussion (famous words plus enumeration)+conclusion (complete paragraph, positive)
