英语选择题:请问选哪个？为什么？请讲解一下，还是这题出错了？谢谢
We have to __ the rain to stop before we go out.
A: wait B: wait until C: wait for D: waited for

Answer 1

C。 have to 的后面必须跟动词不定式，所以把D排除；until做介词时后面仅跟一个名词，而名词后不能再有to do sth; 做连词时后面引导从句，故排除B; wait是不及物动词，排除A.

Answer 2

选b have to解释为不得不 后面跟动词原形所以d排除了，看a wait+介词＋名词 wait for 是等待某物或某人的意思
