Argumentative writing, also called argumentative writing, is a style of analyzing things, discussing things, expressing opinions and putting forward opinions. The author determines the right or wrong of an opinion and establishes or denies a claim by putting facts, reasoning, distinguishing right from wrong and giving examples. Argumentative writing has the characteristics of clear viewpoints, sufficient arguments, concise language, reasonable argumentation and strict logic.

Contrast: Vivid narration indirectly expresses the author's thoughts and feelings, which is different from narrative, introducing or explaining the shape, nature, reason and function of things, and also different from expository. In a word, argumentative writing is an article that convinces people with reasoning, while narrative writing and expository writing are articles that move people with things and teach people with knowledge.

Logical characteristics: the language of argumentative writing must be accurate, distinct, rigorous and targeted.

There should also be a very clear logical relationship between paragraphs, such as total score, contrast, progression and parallelism. Highlight this relationship with the help of turning sentences or related words.
