––You _____ mine. I wasn’t using it then

1. A.
   might borrow
2. B.
   should borrow
3. C.
   must have borrowed
4. D.
   could have borrowed

Answer 1

D
考察虚拟语气。本题是对过去情况进行虚拟，故使用情态动词+have done的形式，排除AB。Must have done是对过去所发生的情况进行肯定的推测，不表示虚拟。Could have done本可以做某事，实际上却未作。结合句意可知D正确。句意：—因为汽车坏了，我昨天没有去上班。—你本可以用我的汽车，我昨天没有开车。
