以疑問詞開頭,對句中某一成分提問的句子叫特殊疑問句.常用的疑問詞有：what who whose which when where how why等.
特殊疑問句有兩種語序：
1．如疑問詞作主語或主語的定語,即對主語或主語的定語提問,其語序是陳述句的語序：疑問詞（＋主語）＋謂語動詞＋其他成分?如：
who is singing in the room?
whose bike is broken?
2．如疑問詞作其他成分,即對其他成分提問,其語序是：疑問詞＋一般疑問句語序?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?
