Generally speaking, there are five ways to put forward the central argument of argumentative writing, including straight to the point, quoting classics, narration, asking questions and directly refuting.
Generally speaking, the central argument of most argumentative papers appears at the beginning of the middle paragraph.
If you want to prove it with arguments, then the first sentence at the beginning of each paragraph must be its argument, and then further truth, examples and analysis.
Generally speaking, all the contents of an argumentative paper are written around its central argument, so we can also analyze it in combination with the content.
