The reference method is changeable and flexible.

Characteristics of argumentative language

When analyzing the linguistic features of argumentative writing, we should pay attention to the following four aspects:

1, the rigor of language. Argumentative essays generally use long sentences, because the more attributive, adverbial and complement elements in long sentences, the more rigorous the reasoning.

2. The motivation of language. Argumentative writing should make the truth clear and convincing, and the language must be aggressive. This momentum can be obtained with the help of appropriate rhetorical devices and some special sentence patterns.

3. The image of language. The language of argumentative essays can sometimes be visualized and humorous to attract readers' interest in reading.

4. Language contrast. When explaining a certain truth, we can use groups of antonyms or antonyms to form a sharp contrast and distinguish praise from criticism.
