As a normal syntax format in Ancient Chinese Period, the Serial Verb Structure “V₁不V₂” is different from the modern Chinese Predicate- Complement-Object Structure. The “V₁不V₂” structure has the distinct semantic feature, syntax feature and pragmatic feature. Each of the “V₁不V₂” structure has a semantic relation of “action-result”, and through different syntax structures this “action-result” semantic relation can be realized. In the dynamic environment where the “action-result” semantic relation realized the pragmatic function of “Structure Center - Descriptive Center” between V₁ and V₂ can be formed. Just because of the special semantic feature, the syntax feature and the pragmatic feature, we can find that there are two sources of the “V₁不V₂” structure. One is from the Descriptive Structure “V₁,不V₂”, another is from the Serial Verb Structure “V₁V₂”. Generally “V₁不V₂” has an important role in the process of development and evolution from the Descriptive Structure “V₁,不V₂” to the Verb-Complement-Structure “V不C(O)”.
