问题补充：

It is very kind of you to do the washing-up, but you it.

A. mustn’t have done

B. wouldn’t have done

C. mightn’t have done

D. didn’t have to do

答案：

A. mustn’t have done

B. wouldn’t have done

C. mightn’t have done

(答案→)D. didn’t have to do

解析：句意：洗了衣服你真是太好了，但是你没有洗的。mustn’t have done表达不对，wouldn’t have done 不会做的，mightn’t have done 不可能做，didn’t have to do没有必要做，根据语境应选D。
