现代汉语疑问句焦点研究

是非问句都存在焦点，但有的焦点透明度较低，需要借助语境确定。特指问句只有一个疑问词时，只有一个焦点；含有多个疑问词时，则有多个焦点；多个焦点之间可以是并列关系。正反问句的焦点总落在“X不X”上。选择问句的焦点可以是选择肢中的某一成分，也可以是整个选择肢。特殊疑问词进入特殊构式后，疑问焦点被消解，产生疑问词的非疑问用法。

Study on Focus of Interrogatives in Modern Chinese

There are focuses in all yes-or-no questions,but some focuses are difficult to be found without context.If there is only one wh-word in wh-questions,there will be one focus.If more than one,there will be more.And these focuses can be coordinate.In positive and negative questions,the focus always lies in 'positive X negative X'.In alternative questions,the focus can be a constituent in the clause,and sometimes also the whole clause.If a wh-word is embedded into a special construction,it will be de-focused and the construction will not convey question any longer.
