As the direct source of today`s Verb-Complement Structure, the Serial Verb Structure has unique conditions itself in syntax structure, semantic relation and pragmatic function. In syntax structure, according to the different semantic features from internal constituent parts V1,V2,O1,O2, the Serial Verb Structure has four kinds of structures, V1V2O，V1OV2，V1O1V2O2 and V1V2.In semantic relation, V1 should show the “action”, V2 should supplement and explain the result which is caused by the V1, and there is a “action-result” semantic relationship between V1 and V2. In Pragmatic Function, the V1 showing the “action” takes charge of the center of the structure, and the V2 complementing and explaining the result takes charge of the core of the expression. Through the analysis of the conditions in syntax structure, semantic relation and pragmatic function, we can find the Descriptive Structure which has direct historical development relation with the Serial Verb Structure. Not only the semantic relation, but also the syntax structure, pragmatic function of this structure are fit for the demands from the Serial Verb Structure. And, as a dynamic developing syntactic structure, the Serial Verb Structure serves as a link between the past - the Descriptive Structure, and the future - the Verb-Complement Structure.
