A pragmatic interpretation of questioning is intended for a discussion of the speech act of questioning (Q-ing) in a pragmatic (context-dependent) fashion. By 'pragmatic' ,the author means something practical and broader than the Levinsonian model. What the author is interested in , inlike most orthodox pragmaticians, is the subjective factors affecting utterance constructing processes. Part One is an examination of the micro-structure of a typical Q-ing utterance (which is a supro-sentential functional entity). Part Two examines the informational properties of Q-ing, based on the theory of relevance,with intention-procedure duality.Part Three examines the interpersonal functions of questioning. Six chapters are devoted to the discussion. The whole paper is written in Chinese, with English and Chinese examples to illustrate my views.
