以疑问词开头,对句中某一成分提问的句子叫特殊疑问句.常用的疑问词有：what who whose which when where how why等.
特殊疑问句有两种语序：
1．如疑问词作主语或主语的定语,即对主语或主语的定语提问,其语序是陈述句的语序：疑问词（＋主语）＋谓语动词＋其他成分?如：
who is singing in the room?
whose bike is broken?
2．如疑问词作其他成分,即对其他成分提问,其语序是：疑问词＋一般疑问句语序?如：
what class are you in?
What does she look like?
Where are you from?
What time does he get up every morning?
How do you know?
