隐喻是人类普遍的一种思维方式,一种认知手段。隐喻认知对多义词的形成起着不可取代的作用。本文从隐喻映射理论、隐喻认知等方面阐述隐喻理论对大学英语词汇教学的启示:鼓励学生联想,深刻理解一词多义现象;分析词汇隐喻文化差异;将语境引入教学。 Metaphor is a common human way of thinking, a cognitive means. Metaphorical cognition plays an irreplaceable role in the formation of polysemous words. This paper expounds the implication of metaphor theory on college English vocabulary teaching from the aspects of metaphor mapping theory and metaphorical cognition. It encourages students to associate and profoundly understand the meaning of polysemy, analyzes the cultural differences of vocabulary metaphors, and introduces the context into teaching.
