虚拟语气讲解与练习
1.辨别if 引导真实条件句和if引导的虚拟条件句的区别
If he has time, he will go with us.= Probably he has time and will go with us.
If he had time, he would go with us.=But in fact he has no time.

与将来的事实相反 1. 行为动词用did2. should + 动词原形3. were to + 动词原形 shouldwouldcould + 动词原形might
3.混合时间的虚拟语气
如果条件句中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。
1)0If I had received the passport yesterday, I would start today.
2)If he had telephoned me last night, I would see him now.
3)If he had followed the doctor’s advice, he would be all right now.
4)If China had not been liberated, the working people would still be leading a miserable life.
4.should/ could / might/ ought to + have done 表示“过去本应该/可以做而实际上却没做”
needn’t have done 表示“过去没必要作而实际上做了”
5.虚拟语气中的倒装句
如果虚拟语气的条件从句谓语动词中含有were, had, could, should，有时可将if省去，而将条件从句的主语置于were, had, should, could 之后。
Had you invited us, we would have come to your party.
Were I you, I would do more practice after class.
Could she lend us a helping hand, she would do so.
6.wish 后面的宾语从句的谓语动词应使用虚拟语气， 表示“可惜…；….就好了；悔不该…；但愿…。”

7.表示命令或建议动词suggest, insist, propose, desire, demand, request, order, command 后的宾语从句中应使用虚拟 should +动词原形； should 不可用would 来替代; 主句所使用的动词时态不限。
8.suggest 为“建议去做…; 命令…”从句用should + do
为“ 说明； 暗示”, 从句用过去时或过去完成时。
1) The doctor suggested that I should take the medicine three times a day.
2) The doctor suggested that my grandmother had caught a bad cold.
9.insist “坚持要去做…，坚持应该去做”，从句用should + do为“坚持表明，坚持说/解释”， 从句用过去时或过去完成时。
10.虚拟语气也用于表语从句和主语从句中，表示间接的命令、要求、请求、建议、决定等，主句的主语通常是suggestion, proposal, request, order, idea 等。表语从句中的谓语动词是should +动词原型，should 可以省略。
11.在主语从句中，当从句用来表示惊奇、不相信、惋惜等，从句的谓语动词用需拟语气形式。其谓语动词时should + 动词原型， 或should 省略。
12．含蓄虚拟条件句：
有时一个假设的情况并不用条件从句表示，而用其它方式来表示，这样的句子叫含蓄条件句。主要有以下几种情况。
1) 用with, without，but for等介词短语来替代条件从句, 它们都可以转换成由if引导的虚拟条件句。如：
We might have died without your help. =We might have died if you hadn’t helped us.
如果（那时）没有你们的帮助，我们可能已经死了。
Without the sun, nothing would grow. = If there was no the sun, nothing would grow.
没有太阳，万物都不能生长。
2) 用or, otherwise, but that, suppose/ supposing (that), provided / providing (that) 等引导的虚拟语气。如：
You didn’t come yesterday, or you would have seen him.
你昨天没有来，否则的话，你就已经看到他了。
I was very busy last week, otherwise I would have come to see you.
我上周很忙，否则的话，我就来看你了。
Supposing I was still a little child, I would study hard from now on.
假如我还是一个小孩子的话，我将从现在开始努力学习。
3) 通过上下文来表示虚拟：这种情况下，需要加以分析。
I would have given you more money, but I was so poor then.
我（那时如果有钱的话）就可以给你更多的钱了，但是我当时太穷了。
I would have called you, but I forgot your telephone number.
我本来可以给你打电话，但是我（那时）忘了你的电话号码。
Having known the fact in time, we couldn’t have said that. = If we had known the fact in time, we couldn’t have said that.
如果我们（那时）及时知道事实的话，就不会说那件事了。
Any man in his position would have done that.
处于他那个位置的任何人都会那样做的。
4）由should +动词原形或者should/could/might have +过去分词构成的虚拟语气。
种情况下，虚拟条件句经常省略，而只剩下主句结构，如：
I should have told you that, but I was afraid that you couldn’t accept the fact.
我本应该告诉你那件事，但我担心你不能接受这个事实。
Tom, you are so lazy! This work should have been finished hours ago.
汤姆，你太懒了！这个工作本应该几个小时之前完成。
13. 在if it were/had been not for …句型中的虚拟语气
If it were not for…,表示对现在事实的假设；If it had not been for…,表示对过去事实的假设。
If it were not for the Internet, everything would be very difficult.
要不是互联网，一切都会变得很难。
