What is the function of rhetoric?

Rhetorical devices include metaphor, exaggeration, parallelism, personification, repetition, duality, rhetorical questions and so on. Rhetoric is a collection of expression methods used in various articles or applications to improve the expression effect.

1, metaphor is analogy, which means using concrete, simple, familiar and vivid things to explain or describe abstract and profound things. This can describe the image of things more vividly and concretely. Both sides of analogy should have the same characteristics. Metaphor aims to clarify ideas in vivid language. In other words, through metaphor, people can know and understand what they don't know, don't understand, don't know and don't know.

2. Personification means writing things into adults with the help of imagination. That is, giving them human words and deeds, thoughts, feelings, etc.

3. Parallelism uses three or more sentences or phrases with the same or similar structure, closely related meanings and consistent tone to form a string. Such sentences can strengthen the momentum of language, express strong feelings and enhance the appeal of language.

4. Exaggeration is a rhetorical way that deliberately enlarges or narrows the image, characteristics, function and degree of things in order to achieve certain expression needs. The function is to reveal the center of the article and inspire people. Set off the atmosphere and enhance the appeal of literature (sentences). Further enhance association; Create the atmosphere of the article.

5. Asking questions In order to attract readers' attention or thinking, first ask questions yourself, and then answer them yourself. That is, ask yourself and answer yourself.

6. Rhetorical questions express clear meaning in the form of questions, that is, only ask without answering, and there are answers in the questions.

7. Duality: Duality refers to using a pair of sentences or phrases with the same structure and the same number of words to express two relative or similar meanings. The most classic works are Du Fu's Ascending to the Top, Falling Leaves Returning to the Roots and I think the Yangtze River is always rolling forward. For the judgment of duality, one lies in sentence pattern and the other lies in emotion. Sentences should be similar and emotions should be the same.

8. Metonymy: refers to borrowing related things instead of what you want to express. Generally speaking, it can be divided into parts rather than whole, concrete rather than abstract, characteristics rather than people. Some students may think that metaphor and metonymy are somewhat similar. Indeed, without systematic analysis, metaphor and metonymy are somewhat similar, but after analysis, metaphor and metonymy are well distinguished.
