This article aims to look into non-prototypical patient object sentences in Chinese in the framework of generative grammar. Based on a full description of the syntactic phenomenon, the article attempts to explain how non-prototypical patient constituents occur as non-prototypical patient objects in dynamic object positions and what syntactic conditions they are subject to. The material object and the instrument object differ from each other due to their different degree of patientiveness and hierarchy of abstractness, which can be testified in the transformation of passive constructions, object extraction, the use of aspect markers, adverbs, and modal particles. As non-prototypical patient objects, however, both the material object and the instrument object must conform to the condition of V`-Reanalysis.
