This paper capitalizes on two peculiar properties of Mandarin Chinese resultative constructions that pose problems for a general theory of argument structure and parametric theory: (a) the widespread existence of unergative objectless resultatives, and (b) the possibility for both unaccusatives and unergatives to be causativized. It is proposed that these properties are reduced to the single possibility in Chinese (but not in English) for an unergative verb to merge as a manner modifier of an inchoative eventuality predicate BECOME in event structure. This parametric property is in turn reduced to a property of Chinese as a language of high analyticity. In opposition to certain recent models, the paper argues for the existence of a syntax-lexicon macro-parameter.
