do you know what is she 还是do you know what is she

do you know what is she 还是do you know what is she
请说明原因
还有 这一类的问题我都分不清
好像说什么作主语
我看到过一句话the boy didn't know what is in his pocket.

是后者：
do you know what is she
一个解释这种句型的技巧是：
把句子改写为：what is she,do you know?
what is in his pocket,the boy didn't know.
就很清楚了.
再问： 你的技巧有问题吧
再答： 这是帮助你了解英语句子结构的技巧，不一定是习惯写法。 朋友，英语是我母语。我也曾是海外英语中学老师。
再问： 可是正确答案是前者
再答： 该“正确”答案是错的。
再问： 请说明原因
再答： 正确答案是 Do you know what she is. 因为你的问题是 do you know what is she 还是 do you know what is she （前者和后者一样） 我把它看错了。抱歉。
