请教What is he doing和What he is doing的句子成分
我觉得he是主语,is doing是动词,what是补语,做is doing的补语?

两句都是：he 作主语,is doing 作谓语,what 作宾语
宾语是动作的承受者,这里what是do的承受者.
补语在主动语态下是补充说明宾语的,是先有宾语,后有补语.如 I want him to sit down
I 是主语,want 是谓语,him 是宾语,to sit down 是补语
两句话的区别是：第一句倒装语序,第二句陈述语序
What is he doing?
I don't know what he is doing.(宾语从句要用陈述语序)
再问：我看到stupidbaby411 的回答觉得有点儿道理，再向您请教一下。 What is he doing你可以把它还原成成述句：he is doing what。所以he：主语；is是系动词做独立谓语， doing what一起做表语，而what又作do的宾语这样理解对不对？貌似“主系表”结构是 he is fine。到底怎么个句子成分呢？还是这两种分析都对？ 1、is doing 作谓语，what 作宾语 2、is是系动词做独立谓语， doing what一起做表语，而what又作do的宾语
再答： is doing 是进行时态，是这个时态不可分割的句子成分。句子分析时，绝对不可分开来看。在 is doing 中，is 已经不是系动词了，它是助动词，是构成进行时态的一部分。只有is 当"是"讲时才是系动词，可独立做谓语。同时要说的是：将来时be going to中的be也是助动词还有被动语态中的be。请其他人不要误导学生。
再问：对对对，你说的太对了。is doing 是进行时态，是这个时态不可分割的句子成分。万分感谢！顿时开悟了！谢谢。
