针对高职学生英语基础相对薄弱,词汇量少,记忆单词的积极性不高的现象,多义词教学成为高职英语词汇教学的难点。认知语义学认为,词义的延伸主要是通过隐喻和转喻的认知思维方式来实现的,而且转喻比隐喻更为基本。本文主要以学生熟悉的人体部位词汇的词义延伸为例研究如何将认知语义学的转喻策略应用于高职英语词汇教学中。 In view of the phenomenon that the English foundation of higher vocational students is relatively weak, the vocabulary is less and the enthusiasm of memory words is not high, the teaching of polysemous words becomes the difficult point of vocational English vocabulary teaching. Cognitive semantics holds that the extension of semantic meaning is mainly achieved through cognitive thinking of metaphor and metonymy, and metonymy is more basic than metaphor. In this paper, we mainly take the extension of the lexical meaning of the human body parts familiar to the students as an example to study how to apply cognitive semantic metaphorical strategies in the vocational English vocabulary teaching.
