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.
