As a parsing-based grammar formalism,Dynamic Syntax, in recent years, has adopted event argument of event semantics in its parsing model. This new advancement, the utilization of event node, could satisfactorily delineate conditionals as well as tense and aspect in English, while in the meantime, it could provide a new perspective for the account of focus constructions like verb doubling cleft construction and lian...dou construction in Chinese. Hence, the introduction of event node in DS could not only overcome its pitfalls and improve its interpretation of cross-linguistic data, but also serve as an ideal formal approach to the interface between syntax, semantics and pragmatics.
