泰如片江淮方言中“V+L”和“V+在+L”结构都可用于表达某物存在于某处,但二者在构成条件、时体特征及构成祈使句的能力等方面存在着差异。这种差异是由两种结构中动词与处所词语之间“在”的有无决定的。此类“在”的主要功能不是引进处所,它的隐现具有表达“未然”和“已然”两种对立的时体意义的功能。 The “V + L” and “V + + + L” structures in the Taijian dialect of Jianghuai can be used to express that something exists somewhere, but there are differences in terms of compositional conditions, body features and the ability to form imperative sentences . This difference is determined by the “being” between the verb and the adverbial word in both structures. The main function of such “in” is not the introduction of quarters, but its appearance has the function of expressing the timeless meanings of both “unnatural” and “already existing”.
