First, the three elements of argumentative writing: argument, argument and argumentation.

(1) argument: it is the author's views and opinions on the issues discussed, and it is the soul of argumentative writing.

1. Argumentative essays generally have only one central argument, and some argumentative essays also put forward several sub-arguments around the central argument. Sub-arguments are used to supplement or prove the central argument. As long as we study the relationship between these arguments, we can distinguish between master and slave.

2. How to find the central argument? Argument should be a clear judgment, a complete statement of the author's point of view, and a complete sentence in form. Location can be divided into: article title, article beginning, article end, article middle, and some need to be summarized by readers.
