摘要
Metaphor and metonymy are viewed as two different figures of speech in traditional rhetoric,while,in cognitive linguistics,both are both conceptual,spontaneous,and unconscious human activities based on thinking and basic experience in the human brain.In some sense,metaphor and metonymy can be a mode of thinking.A Concept is inseparable from perception and perception is inseparable from thinking.The basic composition of metaphor and metonymy is a concept.That is the way they are associated with.This paper aims to build conceptual structures of metaphor and metonymy from the micro perspective and probe into their working mechanisms.The author also lays out their distinctions in terms of basis,principles,span,and effectiveness through analyzing some examples extracted from literary works.
