日语中的主语一直是研究者关注的问题,也是日语学习者的难题。就日语主语存在与否有过激烈的讨论,其中三上章主张废除主语。本文撇开这些问题,在认可主语的前提下,从认知语言学的视角来考察日语主语的语义特征。通过考察我们发现主语的语义是多样的,在定义或理解主语的时候,不能简单地将其看成行为主体。 The subject in Japanese has always been a concern for researchers and also a problem for Japanese learners. There is heated debate on the existence of Japanese subject, of which the last chapter advocates the abolition of the subject. Apart from these problems, this dissertation examines the semantic features of Japanese subjects from the perspective of cognitive linguistics under the premise of recognizing subjects. By examining the semantics of the subject we found to be diverse, we can not simply consider it as the subject of behavior when defining or understanding the subject.
