“V就V在P”是常用口语格式，文章对其语义结构和语用功能进行深入探讨。以形式差异为依据将该格式划分为三个语义次类；并从概念域理论出发，认为它们分别对应于“行域”、“知域”和“言域”，而且处于不同的语法化等级。根据该格式所保留的话题特征，文章推论指出它源自汉语的拷贝式话题结构，进而分析其语义重点和语篇功能。
The paper discusses a frequently-used oral structure“V就V在”P by exploring its semantic characteristics and pragmatic functions. Based on the theory of conceptual domains, it attempts to categorize the structure into three types concerning formal differences. It suggests that these types are domains of acting, knowing, and uttering, which form grammatical hierarchies. It makes a deduction that the structure came from copying the topic structure by its remaining topic feature. And the semantic emphasis and pragmatic function of the structure are also investigated.
