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 manage
D. can have managed

Answer 1

答案B
根据题干中所给出的时间last week可知我们已经做完了工作，已经完成，故排除A、C两项，再结合could have done表示虚拟语气以及与前面的I don’t think…，故说话者想表达的意思是：离开了你，我们本不可能完成这项工作。故答案为B项。
