本文基于英汉“事态限定”范畴的类型学特征，发现汉语“主题提升”句实现“施行性事态限定”，其句法行为以意义的“交互主观性”为理据，体现发话人基于不同概念主体间的互动和协调，引导受话人接受对“事态”的认知性评价。同时，“主题提升”句法行为与话语功能相关。因此汉语的句法类型与凸显的“交互主观性”有一定联系，并且概念性意义实现为语言形式的过程具有动态性。

By studying the typological features of the qualification of states of affairs(SoA)in English and Chinese,this paper discovers that Chinese topic-raising sentences realize "performative qualification of SoA".The syntactic behaviors of Chinese topic-raising sentences are motivated by the intersubjectivity semantics.based on the interaction and coordination between different conceptualizers,the speaker invites the audience to accept his way of evaluating a state of affairs.The topic-raising syntax is also found to be related to discourse functions.The findings in this paper provide proof that Chinese syntactic types are related to the prominence of intersubjectivity semantics,and that the process from conceptualization to linguistic forms is dynamic.
