本文尝试运用概念合成理论分析《红楼梦》中的歇后语。文章首先简要介绍《红楼梦》中歇后语使用的大体情况,然后介绍“概念合成”概念的提出及概念合成理论的内容,并运用概念合成理论分析《红楼梦》中两条典型的歇后语。概念合成理论为歇后语提供了一个全新的视角,可细致地阐释歇后语的认知动因、逻辑推理及意义构建的过程。 This article attempts to use the theory of conceptual synthesis to analyze the twisters in “Dream of the Red Chamber”. The article first briefly introduces the general situation of using the after-sales language in A Dream of Red Mansions, and then introduces the concept of “concept synthesis” and the content of concept synthesis theory, and uses the concept synthesis theory to analyze two typical after-talk in “Dream of the Red Chamber”.
