Abstract:Chinese wh phrases can be used as universal quantifiers and existential quantifiers besides their interrogative use. They get their distributive reading at [Spec, DistP] in the process of derivation. Chinese wh phrases are used as existential quantifiers in yes-no questions, A not A questions or imperative sentences or c commanded by negative morpheme or epistemic adverbs. Whether wh questions, alterative questions, yes no questions and A not A questions are used as rhetorical questions or imperative sentences is mainly decided by pragmatic factors.
