D. had come

 

Answer 1

答案：D
提示：

题目考察if连接的条件句中的虚拟语气结构： 表示未来实现的可能性极小, if从句用“should / were to + do”，主句中“should / would / could / might to do” 例如：If I should / were to so the experiment, I would do it some other way. 表示与现在事实相反，if从句用过去式，主句用“should / would / could / might + to do” 例如：If I had a bike, I would lend it to you. 表示与过去事实相反，if从句用过去完成式，主句用“should / would / could / might + to have done” 例如：If he had been here, he would have helped you.
