“在+处所VP”(B式)和“V在+处所”(C式)是两个具有承继关系的子构式,二者同中有异,共同承继了基于连动构式的平行理据,所以在构式义上同中有异,异中有同,允许一定程度的句法可变换性。本文运用构式语法承继关系理论、语篇理论、交互主观性理论,从句法语序、语义关系、时间顺序和语用驱动等方面梳理二者的承继链接和理据。 “+ VP +” (B) and “V + +” in C + + are two substructures with inheritance relations, Therefore, there are differences and similarities in the meanings of constructions, allowing a certain degree of syntactic transformation. In this paper, we use the constructive grammatical inheritance relationship theory, discourse theory, interactive subjectivity theory, syntactic and grammatical order, semantic relations, chronological order and pragmatic driving to sort out the inheritance links and justifications.
