Question

where do you think has he gone

Where do you think he has gone?
Where do you thing has he gone?
哪个正确?为什么?
do you think可以看作插入语吗？

Answer 1

第一个是正确的.
这句话的陈述句形式是I think (that) he has gone somewhere.
可以看到,这是一个宾语从句.
问题是对从句中的somewhere提问,就应变为：
Where+ 助动词 + I变成you + think he has gone
相似的句子比如：
where do you think you are?
---你以为你在哪?
I think I'm on a race track.
---我想我在跑道上.
