do you know() next,no that's why they are all waiting here for further information

问题描述:

do you know() next,no that's why they are all waiting here for further information
a.what should we do b.what to do c.what can we do

选B
括号里是宾语从句,而宾语从句要用称述句形式,所以A不选,若A改为 what we should do也对.
C的意思不合题意,整句翻译为:“你知道接下来要做什么吗?不知道,这就是为什么他们都在等待进一步的信息的原因了.”
