同学你好，解答如下，希望能帮到你：
间接疑问句是间接引述的用疑问代词提出的问题，而直接疑问句则不需要间接引述。
间接特殊疑问句由特殊疑问词将主语与问句连接起来. 如:
(a) 直接特殊疑问句: Why do you come so late ？
间接特殊疑问句:Mary wanted to know why she came so late.
(b) 直接特殊疑问句:Where are going ？
间接特殊疑问句:He asked me where I was going.
注意: 当疑问词做宾语时,间接疑问句的语序不变,如:
(a) 直接疑问句:Who did you see yesterday ？
间接疑问句:Please tell me whom you saw yesterday.
(b) 直接疑问句:Which room do you prefer ？
间接疑问句:He wanted to know which I prefered the room.
