Thank you for all your hard work last week. I don’t think we it without you.

A. could have managed

B. can manage

C. could manage

D. can have managed

答案：

(答案→)A. could have managed

B. can manage

C. could manage

D. can have managed

解析：考查情态动词表示推测。对过去情况的推测使用“情态动词+have done”的形式；本题中的I don’t think we could have managed it without you中是否定前移，我认为没有你我们是不可能做到的。Couldn’t have done不可能做某事。故A正确。
