1引言在语义学研究领域,多义词研究是一个常议常新的课题。特别是20世纪70年代以来,伴随着认知科学的跨越性发展,研究者开始从人类的认知过程来重新认识语义,基于原型范畴理论提出了一系列认知语义模型,例如Taylor(2003)的连锁模型、Lakoff(1987)的辐射模型、Langacker(2007)的网络模型等。这些模型认为,多义词的语义范畴是一个原型范畴,词的各个义项就是该 1 Introduction In the field of semantic studies, polysemy is a common topic often studied. Especially since the 1970s, with the leapfrog development of cognitive science, researchers began to re-understand the semantics from the cognitive process of human beings. Based on the prototype category theory, a series of cognitive semantic models were proposed. For example, Taylor (2003) , Lakoff (1987) radiation model, Langacker (2007) network model and so on. These models believe that the semantic category of polysemy is a prototype category, the meaning of the word is the
