Those objects what verb“Chi”carries are not only becoming more and more complicated in terms of semantic types, but also expanding the specific range they belong to. From the perspective of semantics, this paper want to work a new studying on“Chi”and the structure of“Chi＋NP”, by analyzing the conceptual sememe and functional sememe on“Chi”and the tools object, way object, result object and purpose object it carries, we can certify the structure’s composition mechanism in a deeper level of semantics. The reason why some special use cases about structure“Chi＋N（NP）”are rational in both Grammar and Pragmatics is that“Chi”coordinate well with“NP”on the level of functional sememe.
