Based on verb types and the temporal relationships between them, this paper tries to divide serial verb constructions into three groups: prototypical serial verb construction, non?prototypical serial verb construction and peripheral serial verb construction, and regards VP1 as adverbial in non?prototypical serial verb construction, VP2 as complement in peripheral serial verb construction. This classification, more clear and reasonable than previous classification, turns out to be a better solution to the problem caused by the traditional classification and sheds light on the understanding of serial verb sentences.
