A. has come

B. did come

D. had come

 

Answer 1

答案：D
提示：

題目考察if連接的條件句中的虛擬語氣結構： 表示未來實現(xiàn)的可能性極小, if從句用“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. 表示與現(xiàn)在事實相反，if從句用過去式，主句用“should / would / could / might + to do” 例如：If I had a bike, I would lend it to you. 表示與過去事實相反，if從句用過去完成式，主句用“should / would / could / might + to have done” 例如：If he had been here, he would have helped you.
