An argument generally has four positions: the title, the beginning, the middle of the article and the end. But it is more often at the beginning of the article, and so is the paragraph argument. When similar statements appear at the beginning and the end, the starting argument and the ending echo argument.

Some argumentative arguments are expressed in clear sentences in the article, and we just need to find them out; Others are not directly expressed in clear sentences and need to be refined and summarized by readers themselves. The summarized sentence should not contain rhetorical devices.

Note: rhetorical questions and figurative sentences cannot be used as arguments, but must be declarative sentences.
