1, metaphor and analogy are different in nature.
Metaphor heart must be two different things. For example, people cannot be compared with adults, one voice cannot be compared with another voice, and one trait cannot be compared with another.
(2) There must be a stage between two different things. For example, catkins fall like snowflakes. Catkin and snowflake are two different things, but they are very similar.
(3) Although comparison is two different things, it does not require similarities between them. For example, peach trees, pear trees and apricot trees are full of flowers to catch up with. Write these trees directly as adults, endow plants with human behavior, and integrate trees with people.
2. Different sentence structures
The structure of figurative sentences consists of noumenon, vehicle and metaphor, such as A is like B, A is like B, etc. It's not helpful to describe thing A directly with thing B. Like the northwest wind, like a beast. This is a metaphor. The northwest wind came at me with its teeth bared. This is a comparison.
