Abstract:Some lexicalist studies argued that the resultative constructions in English should be divided into two classes, true and pseudo, according to the situation type of main verbs of clauses.However, these studies neglected the function of the RP, which can add an endpoint to the so-called action verb, and realize the endpoint of accomplishment verb and make it prominent.The syntactic features of so called true and pseudo resultative constructions are very similar, so the semantic criteria can not be supported by syntactic evidence.The author argues that resultative constructions originated from different sources, and blended into one in Modern English.
