no one knows ____ ,so we can do nothing about it.

题目

no one knows ____ ,so we can do nothing about it.
A how to do next
B how to do the next
C what to do the next
D what should we do next

答案

C
没有人知道下一步做什么,所以关于这件事我们什么也不能做.
答案不能是B,因为HOW 是副词,不能作DO 的宾语,根据这点排除A与B,而D的语序错,宾语从句应该是陈述句语序.如果改为what we should do next .就对.
