“VPNeg”式反复问句包括“VP不”、“VP否”、“VP未”和“VP无”等四种形式。本文对这四种形式的反复问句的来源进行了一番探讨,认为“VP不”式反复问句源於称代,“VP否”式反复问句同样也源於称代,“VP未”式反复问句源於带有“VP未VP”结构的句子后一个“VP”的删除,“有NP无”式反复问句源於带有“有NP无NP”并列词组的句子后一个“NP”的删除。这四种反复问句在形成的过程中均受到语言经济原则的影响。 “VPNeg ” repeated questions include “VP does not ”, “VP no ”, “VP not ” and “VP no ” and other four forms. This paper explores the origin of these four forms of repeated questions, that “VP not ” repeated questions from the generation, “VP no ” repeated questions also come from generation , “VP not ” type repeated question originates from the deletion of a “VP” after the sentence with “VP not VP” structure, and “no NP” “NP NP without” clause after the phrase “NP ” delete. The four repeated questions in the process of formation are subject to the principles of language economy.
