____ your support,we might have succeeded in performing the last.
A、If we have
B、If we would have had
C、If we had
D、Had we had
【正确答案】：D
【题目解析】：D译文：如果有你的支持，我们的最后演出就会取得成功。解析：从结构上判断，此题属虚拟语气，叙述上事实情况相反。主句用might+have done ，从句要用过去完成体。D.Had we had = If we had had ,结构正确，是正确答案。A.C属时态不正确。B.If I would have had,不符合虚拟语气从句结构要求。
