2019年mpa考试英语真题——虚拟语气276

{01}Thank you for all your hard work last week.I don’t think we ______ it without you. A.can manage B.could have managed C.could managed D.can have managed 解析：由语境可知这里要表达的意思是：如果没有你们辛勤的工作，我们不可能处理好这件事。很显然，这是对过去发生的事实的虚拟，所以要用could have done，故应选B。
本题选B。

{02}— Catherine, I have cleaned the room for you.
— Thanks. You ______ it. I could manage it myself. A.needn’t do B.needn’t have done C.mustn’t do D.shouldn’t have done 解析：根据句意可知Catherine对对方为她打扫了房间表示感谢并提到对方本来不必为她打扫房间。很显然对方打扫房间是过去所为，表达“去不必做某事”用needn’t have done sth.
本题选B。
