介词框架“PX时”的表时功能及虚化机制研究

On the Temporal Function of Prepositional Framework "PX Tense" and Its Grammaticalization Mechanism

汉语介词框架"PX时"通常在句子里中做状语,常被看做是汉语的同时性时间结构。通过对一系列的语言事实考察发现,它在表达时间范畴时既可以与句子的主要谓语动词是同时关系,也可以是非同时关系。在语义虚化的促动下,这一介词框架还能表达假设关系和条件关系。

The prepositional framework of ＂PX tense＂ in Chinese is usually used as adverbial in a sentence, and is regarded as concurrent time structure. By conducting studies on a series of linguistic fact, the author finds that when it is used to represent time, the PX tense could be concurrent or non-concurrent with the predicate verb of a sentence. Promoted by semantic grammaticalization, it can also be used to express hypothetical and conditional categories.
