是非特指双层问的功能及其话语策略

Complex Interrogatives With Both Yes-no and Wh-Questions:Function and Discourse Strategy

本文讨论"你有什么需要我帮忙吗?"这类兼有是非问与特指问某些特征的是非特指双层问,重点讨论其内部类型、双层焦点与话语策略。是非特指双层问实际上包含两个不同层次的问句:既满足一般问句的需求,也适应更进一层特指问句的需求,外层是非问是次要焦点,内层特指问才是主要焦点。其关键是话语策略在起作用,符合礼貌原则、经济原则与灵活原则。最后,本文对这类特殊疑问句形成的历史轨迹进行了初步探讨,指出它可能是从反问句经过诱导句演变而来的。

The paper explores special interrogatives like ＂ni you shenme xuyao wo bangmang rna ？＂, which combines the nature of both yes-no question and wh-question, one is to ask yes or no and the other is to further a special question. The surface yes-no question is the minor focus while the inner wh-question is the major focus. The key factor is the effect of discourse strategy with the application of Politeness Principle, Economical Principle and Flexibility Principle. The paper stresses their categories, the double loci and discourse strat-egy. At last, the diachronic evolution process of this kind of special interrogatives is dis- cussed and it was proposed that these complex interrogatives may have developed from rhe-torical questions through induced sentences.
