答案:B
提示:
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. 并注意,if从句中,若有were, had, should三词时,可省去if,同时采用主谓语倒装形式来表示条件。 例如:Should anyone call, please take a message.
