虚拟语气1
If引导的虚拟语气用于非真实条件句
❤与现在事实相反：从句用“动词的过去式（be动词一律用were）”
主句用“would/could/should/might + 动词原形”
如果我有时间，我就会参加你的晚会。
例句：If I had time, I would attend your party.
❤与过去事实相反：从句用“had + 过去分词”
主句用“would/could/should have + 过去分词”
你当时不让我来开车。
如果我们轮流开车，你就不会觉得那么累。
例句：You didn’t let me drive. If we had driven in turn, you wouldn’t have got so tired.
❤与将来事实相反：从句用“动词的过去式；should + 动词原形； were to + 动词原形”
主句用“would/could/might/should + 动词原形”
如果明天下雪，我们就照相。
❤混合虚拟条件句：如果条件从句的动作和主句的动作不是同时发生，主句和从句的谓语动词的形式应分别根据各自所表示的时间加以调整。
If I were as clever as you think, I should have been rich by now.
如果我像你想得那么聪明，现在就会很富有了。
(从句是真实条件句，主句是虚拟语气)
If you had worked hard, you would be very tired now.
如果你真的努力工作了，你现在就会感到很累的。
（从句指过去，主句指现在）。
虚拟语气-1..
3、可能违背将来事实的假设 这里指的是将来不大可能发生的假设，或者虽有可能发生， 说话人主观上不希望发生的假设。这种假设相当于汉语中 常用的“万一”，“居然”，“竟然”等含义。例如： If he should fail, we would encourage him to try again. 万一他失败，我们就鼓励他再试一次。 If I were to do it, I would do it in a different way. 要是我来做这件事，我会是另外一种做法。 We would wipe them out if they should attract us. 如果他们胆敢进攻，我们就将他们消灭。 If it should rain tomorrow, what could we do? 万一明天下雨，我们能做些什么呢？ If the rocket should fail in a few seconds, it would certainly explode.如果火箭几秒钟内竟然向下坠落，那就一定会爆炸。
5、连接词 if 的省略 如果条件从句的谓语包含有had, should 或 were，有时 if 可以 省略。这时had，should 或 were 要移到主语前面，形成倒装。 （这种句型主要见于书面形式。） Had he not been ill, he might have come. 要不是生病，他是会来的。 Were I to do it, I would do it in a different way. 要是我来做这件事，我会是另外一种做法。 Should it rain tomorrow, what could we do. 万一明天下雨，我们能做些什么呢？ Were it not for his help, we couldn’t have got over the difficulties. 如果不是因为他的帮助，我们就克服不了这些困难。

四、用在as if/ as though引导的方式状语从句中 用在 引导的方式状语从句中 She loves the orphan as if he were her own son. He talked as if he had known everything. 五、It is (high/ about) time that…(用过去时) that…(用过去时 用过去时) It is high time we began to work. It is high time that we should begin to work. It is time that children went to school. It is time that children should go to school.
*可以把 省略，将were, had, should 可以把if省略 可以把 省略， 提前， 提前，构成倒装 Should it rain tomorrow, we would stay at home. Were it to rain tomorrow, we…. Had I not taken your advice, I would have made a bad mistake.
二、在非真实条件句中（所提出的假设 在非真实条件句中（ 实现的可能性极小或与事实相反） 实现的可能性极小或与事实相反） (1)与现在事实相反 (1)与现在事实相反 I would go if I had time. If there were no air, people would die. (2) 与过去事实相反 If you had got there earlier, you would have caught the bus. If I had not taken your advice, I would have made a bad mistake.
