The central argument exists in argumentative essays, and narrative essays generally only mention the central idea or theme idea. To find the central argument, we can consider it 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) put forward the central argument with a connecting sentence in the middle of the article. ⑤. The article does not directly put forward the central argument, but always discusses it ... 2. To analyze the argumentation idea of the article, we must first understand the structure of the general argumentative paper: asking questions (introduction)-analyzing problems (this theory)-solving problems (conclusion). In fact, it is to add some words such as "first", "then", "next" and "last" on the basis of paragraph level. When doing this topic, we should pay special attention to the expression at the beginning and the end. The contents at the beginning include: (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) Issue a call ... or exhort people ...; (4), supplementary argument ...... (Sometimes we will examine the role of this aspect, and its role is to make the argument more rigorous. To do 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 this way: first, quote the famous saying of French thinker Pascal that "man is a thinking reed" and put forward the central argument that "man's nobility lies in the soul", and then use the examples of Archimedes and Wilde to prove that "inner spiritual wealth is more precious than external material wealth". Finally, taking a girl studying on the train as an example, it warns people that "people should keep pure spiritual pursuit". Analysis of the language characteristics of argumentative writing: The analysis of the language characteristics of argumentative writing is relatively fixed, with only two perspectives: (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. ). And the stylistic features are just making a fuss about four words with strict logic. One thing that needs special attention is that there must be concrete sentence support to do this kind of topic. That is to say, take the specific cases in the article as examples of 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 and so on. (2) Demonstration method: refers to the function of demonstration method. (3) Writing skills are relatively fixed, such as: (1), combining case argumentation with reason argumentation (narration and discussion); (2) Demonstration method is the main method. Similarly, doing this kind of topic should be supported by concrete sentences, that is, analyzing it with concrete examples in the article. 5. The function of paragraph structure: (1), which leads to the following (all); (2) Summarize the first (full) articles; (3) As a connecting link between the preceding and the following, as an argumentative paragraph, it must be answered in combination with stylistic features. If the opening paragraph often leads to the central argument (topic), then we can refer to the following two examples of specific answer formats to use or adapt: ①. At the beginning, the central argument (or topic introduction) is put forward by writing an example. (3) at the beginning, by quoting interesting stories of celebrities (or …), the topic of central argument … (or leading to …) is put forward, which also plays a role in attracting readers to read and enhancing the interest of discussion.
