概念

特殊疑问句是在英语中以特殊疑问词开头，对句中某一成分提问的句子。根据疑问词分类有疑问代词、疑问副词、疑问形容词：

疑问词	包含
疑问代词	what、who、which
疑问副词	when、where、why、how
疑问形容词	whose

变形

知道特殊疑问句的主语，询问 "他/他们/我可以做什么" 之类的问句时，就是由主语的情况。；不知道特殊疑问句主语，询问 "谁可以做什么" 之类的问句时，就是没有主语的情况。

特殊疑问词可以由一般疑问句变形而来。在一般疑问句的句首加上疑问词，去掉一般疑问句的答案。

有主语的情况

【陈述句】Sam will be back on Friday.
【一般疑问句】Will Sam be back on Friday?
【特殊疑问句】When will Sam be back?

一般疑问句中，具体回答了 Sam 什么时候回来。特殊疑问句是不包含答案的疑问句，所以要把 Sam 什么时候回来的时间给去掉。

其他案例：

陈述句	一般疑问句	特殊疑问句
They were walking fast.	Were they walking fast?	How were they walking?
He was watching a film.	Was he watching a film?	What was he watching?
She left beacause it was late.	Did she left because it was late?	Why did she left?

没有主语的情况

【陈述句】Sam will be back on Friday.
【一般疑问句】Will Sam be back on Friday?
【特殊疑问句】Who will be back on Friday?

不知道特殊疑问句的主语，用疑问代词作主语。

其他案例：

陈述句	特殊疑问句
John knows the way.	Who konws the way?
The wind damaged the building.	What damaged the building?
Jean likes to playing tennis.	Who likes to play the tennis?
