虚拟语气： 1. 对现在情况的虚拟： If后面用动词过去式，主语用would/could/should/might 动词原形 例句1：如果我是你，我会选择在小城镇工作。 英语1：If I were you, I would choose to work in a small town. 例句2：如果现在有地图，我们能很容易地走出森林。 英语2：If I had a map now, we could easily get out of the forrest. 2. 对过去情况的虚拟： If后面用 had done/had been/had been done，主语用 would/could/should/might have 动词过去分词 例句：如果昨天没有你的帮助，我不会赶上公交车。 If it had not been for your help yesterday, I couldn’t have caught the bus. 3. 对将来情况的虚拟： If后面用should do或动词过去式或were to do，主句用would/could/should do 例句：如果我们明天能来，就能见到总经理。（实际上明天来不了） If we should come tomorrow, we could meet the general manager. 4. 错综时间条件句： 例句1：如果当时听我劝，你现在就不会有麻烦了。 英语1：If you had taken my advice, then you wouldn’t be in trouble now. If句是对过去的虚拟，所以用过去完成时； 主句是对现在的虚拟，所以用would 动词原形。 例句2：如果我是个更优秀的老师，也许我就能打动他们了。 英语2：If I were a better teacher, maybe I could have reached them. If句是对现在的虚拟，而主句是对过去的虚拟。 5. If only后面跟虚拟语气，表示“要是……就好了。” 例句1：要是我年轻一些就好了。 英语1：If only I were younger. 例句2：要是我昨天来参加聚会就好了。 英语2：If only I had come to the party yesterday. 注意：Only if是“只要”的意思，不涉及虚拟语气。
