问题描述:

.The teacher has already told me but I'm still not clear ____to do next.
The teacher has already told me but I'm still not clear ___ to do next.
A.how B.what C.why D.whether
为啥选B不选A呢..
有什么不一样吗?...

因为clear后面接一个宾语从句,宾语从句中,记住
有两种常用情况
【what to to】做什么
【how to do it】怎样做
用how这个疑问词提问的时候都后面要加it,但是题目没有,所以不选A
翻译:老师已经告诉我但我仍然不清楚下一步该做怎么.
