There are two relationships between thesis and research: (1) Writing a thesis is because the research has produced results; (2) Because I have to write a paper, I have to study something. Obviously, the former is based on feeling, and the "direction" is already there. Only the latter has the problem of determining the research direction of the paper. For the purpose of publishing papers, some students strive to get a good ranking in the exam. Although the cause and effect are reversed, it is by no means useless. In order to write a paper, the direction can point to a small field that has not been summarized, and the expected result is a summary paper; It can also be aimed at the unpopular position in a certain theoretical system (lack or lack of depth in theory or practice), and the expected result is an innovative paper. No matter which direction is determined, it needs to be based on a full understanding of the existing related research results.

Actually, this is very simple.

Generally speaking, the emergence of the central argument in argumentative writing has its own laws. First of all, we should master the basic knowledge of argumentative writing, such as the three elements of argumentative writing: argument, argument and argumentation. And to be able to judge the content of an argumentative paper, which are arguments, which are related to arguments, and what argumentation methods are used. Argumentation methods include: case argument, reason argument, quotation argument, metaphor argument, contrast argument, etc. Generally speaking, arguments are found in truth arguments or quoted aphorisms.

In addition, we need to know several structures of argumentative writing and learn to judge what structure to analyze. The structure of argumentative writing generally includes: total score, total score, total score and so on. Then, when we judge the arguments of an argumentative essay, it is much easier to find or summarize them in the general part of the argumentative essay.

In addition, judging from the overall layout of most argumentative papers, the author always likes to put the central argument at the beginning of the article for logical and organizational reasons, which is called getting to the point, so that the central argument of the article is straightforward and clearly appears in the reader's field of vision. Then, the central argument of some argumentative papers is at the end of the article, which is called ending with a point, giving people a sense of pleasure in one go.

Well, having said so much, maybe everyone has a clear understanding. As long as we have a solid foundation and know some common sense of argumentative writing style and writing rules, we can easily find the central argument of argumentative writing or solve other problems.
