On the basis of diachronic linguistic evidence SHI (2020)puts forward the notion of “super construction” and proposes that the evolution of grammatical constructions in Chinese such as the passive construction derives from the diachronic change of “super constructions”. It is found that the notion of “super construction” and the role it plays in linguistic system might meet theoretical and methodological problems, and also deviate from the spirit of construction grammar. In the framework of cognitive grammar, this paper re-analyzes the generalization such as the adverbial-verb construction and the verb-complement construction found in SHI (2020),and proposes that they embody the cognitive dynamicity of the modern Chinese grammar at the phrasal level. The emphasis on the coding of this cognitive property may also contribute to the structural distinction of modern Chinese from pre-Qin Chinese.
