本文基于原型理论和语法化理论,对“有+NP+VP”无主句中“有”的词性和用法进行了分析,得出以下结论:“有+NP+VP”无主句不是兼语式,其中的“有”不是动词而是语法标记;“有”提升NP的有定性,可以看作有定标记;通过“有”的引进介绍,NP成为一个新话题,“有”可以看作话题标记;“有+NP+VP”无主句与无定NP主语句的根本区别是语用功能不同,前者用于话题陈述,后者用于情景描述。 Based on the prototype theory and grammaticalization theory, this paper analyzes the part of speech and usage of “有 ” in “有 + NP + VP ” without clause and concludes that “+ NP + VP The main sentence is not a combination of language, which ”has “ is not a verb but a grammar mark; ”there “ to enhance the NP has qualitative, can be seen as a definite mark; through the introduction of introduction, NP is a new topic, ”has “ can be regarded as the topic mark; ”+ NP + VP " The main difference between the main clause and the indefinite NP main clause is that the pragmatic function is different. The former is used for the topic statement, The latter is for scenario descriptions.
