问题描述：
No one has told us____,so we need your help.
A.what to do it B.what should we do C.how to do D.how to do it 该选哪个?为什么?为什么不选A?
答
选D
意思是：没人告诉过我们该怎么做这件事，所以我们需要你的帮助。
答
D
A. 用what to do就表示“做什么”了，加个it是多余的；因为do的宾语就是what
B. 语序不对，应该是what we should do, 因为它在句中是宾语从句，要用陈述语序
C. do后少了宾语it, 因为do的宾语不可能是how, 不能do how
答
D
do为及物动词，what作do宾语，所以A多了it
答
选 D
如果选A， 要把 it 去掉
答
what to do with it ,how to do it,这样才正确
