Afterwards, the traditional metaphor rhetorical view gradually has been formed into three schools in its long development history with three typical theories: comparison theory, substitution theory and interaction theory。 Comparison is made by the ancient Greek Aristotle。 Comparison theory is actually a theory of the mechanism of metaphor interpretation, where the basic idea is that every metaphor implies a simile。 In other words, each metaphor is omitted simile marked word such as “like”。 In the first century AD, the Roman rhetorician Quintilian proposes substitution theory。 Metaphor is actually that one word replaces the other word phenomenon。 That is to say, metaphor is an alternative lattice, substituting one thing for another, or by implication。 In 1936, I。 A。 Richards proposes the famous metaphor interaction theory。 In his view, metaphor is judged by the existence of “interaction” between two subjects, whether a word is used as a metaphor, whether it provides an ontology and a metaphor, interacting to produce an inclusive meaning。 If ontology and metaphor cannot be discovered, the word is used in the original meaning, however, if it can be pided into at least two kinds of interactive significance, then the word is used as metaphor。
