作为“边缘功能语类”的Ex

Ex as a Peripheral Functional Category

本文从理论内部和经验数据上论证提出Ex作为“边缘功能语类”的合理性,并且主要利用Chomsky(1995)关于“等距”的原理,解决存现句研究中长期有争议的问题:(1)主谓一致是在存现动词和其后的表示存现对象的名词性词组之间而不是和there之间;(2)存现动词后的表示存现对象的名词性词组的格核查。

This paper argues, theoretically and empirically, for the plausibility of establishing Ex as a Peripheral Functional Category （PFC）, aiming to solve, based upon the Equidistant Principle proposed by Chomsky （1995）, two lingering problems in existential constructions： （1） the agreement between the existential verb and the postverbal nominal phrase instead of there; （2） the Case-checkihg problem of the postverbal nominal phrase.
