同源结构与同源动词研究

同源动词包括非宾动词和非作格动词。非宾动词的同源宾语实际上是个副词,占据附加语位置.无格特征核查要求。在同源结构中,非作格动词由名词衍生而来,同源宾语是该名词的拷贝,占据动词的内部题元位置,有格特征核查要求：通过与Tr合并,名词N派生为动词,其拷贝与Tr形成核查关系,由Tr核查其宾格特征。

On Cognate Construction and Cognate Verbs

Cognate verbs include unaccusative and unergative verbs.Cognate object of the unaccusative verb is an adverb,occupying an adjunct position,having no case to be checked.In a cognate construction,the unergative verb is derived from N;the cognate object is a copy of N,holding the internal argumental position,having case to be checked： via merging with Tr,N is derived into V;its copy establishes a checking relation with Tr which checks accusative case of the copy.
