The central argument exists in argumentative essays, and narrative essays generally only mention the central idea or theme idea. Looking for the central argument can be considered from the following five aspects: 1, the way the article puts forward the central argument: ①, the title of the article points out the central argument; ② Put forward the central argument at the beginning of the article; ③ At last, the article summarizes the central argument; 4. In the middle of the article, put forward the central argument with a connecting sentence. ⑤ The article does not directly put forward the central argument, but always focuses on …2. To analyze the argumentation ideas of the article, we must first understand the structure of general argumentative papers: asking questions (introduction)-analyzing problems (papers)-solving problems (conclusions). In fact, analyzing the argumentation idea of argumentative essays is to add some words such as "first", "then", "then" and "last" on the basis of paragraph level. When you do this topic, you should pay special attention to the opening and closing sentences. The content at the beginning is: (1), putting forward the central argument; (2), lead to the topic; In the above two aspects, it is necessary to specifically answer the specific tests that put forward the central argument or lead to the topic, some through famous sayings, some through celebrity anecdotes, and some through anecdotes and jokes. The final content: (1), deepen the central argument and put forward the conclusion of …; (2) Repeating or strengthening the central argument ...; (3) Appeal ... or exhort people ...; (4) Supplementary argumentation. (Sometimes, the role of this aspect is to make the argument more rigorous. Doing this topic is to specifically state the introduction, theory and conclusion of the article. For example, in the article "Man's nobility lies in the soul", we can express it like this: firstly, we quote Pascal, a famous French thinker, "Man is a thinking reed" and put forward the central argument that "Man's nobility lies in the soul", then we quote Archimedes and Wilde to prove that "inner spiritual wealth is more worth cherishing than external material wealth", and finally, we quote a girl who is studying on a train as an example to exhort people that "one should keep a pure spiritual pursuit. 3. Analysis of the language characteristics of argumentative essays: The angle of analysis of the language characteristics of argumentative essays is relatively fixed, with only two angles: (1) language characteristics; (2) Stylistic features. To do this kind of topic, we should master some key words of language style: concise and plain, vivid and humorous, implicit and euphemistic, rich in literary talent and so on. The stylistic feature is that it is enough to make a fuss about the word strict logic. One thing that needs special attention is that doing this kind of topic must be supported by specific sentences, that is, using specific example sentences in the article as examples for analysis. 4. Analysis of the characteristics of argumentative writing There are many angles to analyze the characteristics of argumentative writing, such as rhetorical devices, argumentation methods and writing skills. (1). Rhetoric: for example, metaphor can be combined with the characteristics of metaphor, that is, vivid image; For example, parallelism enhances the momentum of the article argument; For example, quoting ancient poetry makes the article rich in literary talent. (2) Model Law: Talking about the function of reference model law. (3) The writing techniques are relatively fixed, and the common ones are: (1), the combination of example and argument (narrative and discussion); (2), give priority to ... model law. Similarly, doing this kind of topic must be supported by specific sentences, that is, using specific examples in the article as examples of analysis. 5. The function of paragraph structure: (1), leading out (all) below; (2) Summarize the first (full) articles; (3) connecting the preceding with the following. As an argumentative paragraph, it must be answered in combination with stylistic features. If the function of the opening paragraph is often to lead to the central argument (topic), then we can refer to the following two examples of the standard answer format to use or adapt it: ① At the beginning, we put forward the central argument … (or lead to the topic of …) by writing an example of …. (2) At the beginning, by quoting famous sayings, put forward the central argument … (or lead to the topic of …). (3) At the beginning, by quoting interesting stories of celebrities (or …) to put forward the central argument … (or …) also played a role in attracting readers to read and enhancing the interest of discussion.
