“数量·形”结构在现代汉语中并不少见,对于这种结构前人也作了一定的研究,但是对其形成的原因未曾作过深入探究,大多是从修辞的角度来研究。本文就是要深入挖掘这一结构的形成原因,主要从语言的内在因素和人们的主观因素两个方面来进行探讨分析,进一步解释“数量·形”结构存在的必然性。 The structure of “quantity, quantity and shape” is not uncommon in modern Chinese, and some studies have been made on the predecessors of this kind of structure. However, the reasons for its formation have not been explored in depth, mostly from the perspective of rhetoric. This article is to dig out the cause of this structure in-depth, mainly from two aspects of language’s internal factors and people’s subjective factors to explore and analyze, and further explain the necessity of the “number and shape” structure.
