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.
