Metaphor teaching in education and teaching is a very rich form of expression for people to carry out teaching activities. The teacher makes a metaphor through what the student is familiar with, and vividly expresses his inner meaning. Let students better understand this metaphor, which contains people's understanding and cognition of education. Through metaphor teaching, we can better analyze the values and ideas behind the phenomenon of education and teaching. Before the teaching of educational metaphor, we must first understand what metaphor is, and we will use metaphor to describe it. We can describe what we know by analogy. Through the implicit transformation between metaphor and metaphor ontology, we can express the effect of metaphor well, make readers understand it better and introduce its internal logic and function.
