问题描述:

I don't know ____________.A how to do it B what to do it C what I should do it D what I should do
选择.请回答都有哪个答案是正确的,为什么.其它的为什么不对?

b应该改成B what to do
c应该改成C what I should do或者How I should do it?
至于D, 我认为AD都是对的--我不是乱说的

A

a
不为什么

I don't know 与 what to do
或者是 how to do it 连用。
C错在 多个it.
选A和D

how是“怎么”,后要加一个宾语“it”,what是“什么”,后不用加宾语.所以是AD拉!按我们老师说的,就是把它变成陈述句,比如D,变成陈述句就是I should do what,讲得通吧!而C,I should do it what,有两个宾语~

A,D,正确.习惯搭配哦.
