We really don't know_______.()A.which one to choose B.which one chooseC.to choose what D.to choose which one

问题描述:

We really don't know_______.()
A.which one to choose B.which one choose
C.to choose what D.to choose which one

A 说不清楚 这就是一个宾语从句吧 还是什么从句 反正后面该倒装

a
意思:
我们确实不知道选哪一个。
which one代表了主语
don't know how to do something 为固定句式

选A
句意:我们确实不知道选哪一个.
don't know后面只能加名词动名词等等
就先排除C,D
而which one to choose 就和what to do之类的一样
可以用作固定句式,常考
