问题描述：
Well,that was really a good meal.I＿＿you were a really good cook.B:Thank you.A.didn't
A:Well,that was really a good meal.
I＿＿you were a really good cook.
B:Thank you.
A.didn't know B.don't know
C:haven't known D.hadn't known
该选哪一个啊?就在A和D之间,
还有,另一套题中D选项是know,所以选A,根据过去完成时的用法,总感觉这个不是很严密
根据过去完成时的用法,情境中应该描述的是过去吃完饭的过去，感觉选D啊，纠结
答
A,因为从底下的回答可以看出,他现在已经知道了,但之前不知道,没有持续的意思在里面,只是单纯的过去不知道,所以用过去式!
