Mary did not go to bed until she __all the housework Ahad finishedBhas finished CfinishedDfinishes
为什么不选A 答案是C

比如：
It was not until he came that I left.
I didn't go to bed until I finished my homework.

因为你前边有个did你看到没,所以可以确定until后面也用一般过去时
整个句子都是一般过去时!
until后面是没有规定具体要用什么时态的.所以只能看前半部分.前面是什么时态,后面就是什么时态.
不懂还可追问!
