以特殊疑问词开头,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.
可先分为3种:
疑问代词：what,who,which,whose,whom
疑问副词：when,where,why,how
疑问形容词：what（which,whose）+名词
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?
