问题描述:

do you know who is my teacher?
or "do you know who my teacher is?"
which is riht,and why?

Do you know who is my teacher?正确
因为Do you know 是插入语。

do you know who is my teacher?
正确,因为who在从句中做主语,所以who is my teacher是陈述语序。

第二种对,宾语从句用倒装语序

do you know who is my teacher? 正确, 这是个复合句
do you know是主句, Who is my teacher 是宾语从句,宾语从句是陈述语序: 主语: who, 谓语: is, 表语: my teacher.
翻译: 你知道谁是我老师吗?
