Please explain what simile, metaphor, metonymy and pun are, and give examples.

Simile: A clear metaphor is a rhetorical device, which connects two different things with certain features. The expression of simile is: A is like B.

For example, snowflakes fly like goose feathers.

Metaphor: Metaphor is the simultaneous appearance of ontology and vehicle, and the relationship between them is consistent in form. It is said that A (ontology) is (metaphor) B (vehicle). Metaphor is often used to express judgment words, such as yes, success, success and change. Metaphor is also called metaphor.

For example, she is a night pearl, which radiates brilliant light in the dark night.

Metonymy: When you speak or write an article, you don't directly say what you want to express, but borrow someone or something closely related to it instead. This rhetorical method is called metonymy. Body double is called "noumenon" and body double is called "borrowing body". "Ontology" does not appear, but "borrowing body".

For example, the green hills on both sides of the strait are opposite, and the solitary sail is a part of the whole.

Pun: Using the polysemy of words and homonymy (or homonymy) conditions, the sentence is intentionally made to have double meanings, that is, pun.

For example, it is clear that it is winter all around, and it is cold and air-conditioned. Lu Xun's Kite

("Cold power" and "air conditioning" refer to the weather and also to a conservative society. )
