I don't know who do you think you are和 I don't know who you think you are的差别
如题,一个有do 一个没有do.我知道who do you think you are是你以为你是谁的意思.后面一句我是听一首英文歌的·歌词.

前一句的表达是不规范的.
I don't know who you think you are.
我不知道你以为你自己是谁.
who引导的部分是宾语从句,要使用陈述语序,即主语在前,谓语动词在后,不需要助动词do,does或did.前一句问题就在于是疑问语序,要把助动词do去掉,就成了后一句的规范表达.
