“比”字句“小王的爷爷比小李的硬朗”之所以不能说,是因为“小李的”转指“爷爷”不能成立。本文在前人研究的基础上,运用认知语言学“转喻的认知模型”理论,从认知框架和显著度的角度,分析了其转指不能成立的原因。 “Than ” than “Wang’s grandfather than Tony’s tough” Can not say that because “Li’s ” refers to “Grandpa ” can not be established. Based on the previous researches, this paper uses the cognitive linguistics “cognitive model of metonymy ” theory to analyze the reasons why the transfer can not be established from the perspective of cognitive framework and saliency.
