虚拟语气与倒装句（教师版）
什么是虚拟语气(subjunctive mood)?
If I were you, I would not do like this. 要我是你，我就不会这样做
I wish I became a millionaire. 要是我是个百万富翁多好啊
口头解释上面两个例句后引出虚拟语气的概念
表示说的话不是真实发生，只是一种假设，主观愿望，猜测，建议等非真实的情况。
今天主要讲在条件句中虚拟语气的使用情况
Q: 那是不是所有的条件句都用虚拟语气？这里可以提问同学，进行互动后给出正确答案
一．分类
1. 真实条件句，表示的假设是有可能发生的，此时主句不用虚拟语气。
e.g. If I have time, I will do the homework. (口头解释分析这个句子)
2. 虚拟条件句，表示的是一种假象，与事实相反或不太可能会发生，那就要用虚拟语气
e.g. If I were you, I would do the homework. (口头解释分析这个句子)
二．用法
总结：从句都往过去推一个时态。
与现在相反--过去，与过去相反--过去的过去（过去完成），与将来相反--过去
三．重点解析
1. l would/should/could/might主句谓语中的should主要用于第一人称后；would表示结果还表示过去常常做某事，might表示可能性，could表示能力、允许或可能性。
比较：
①If you tried again，you would succeed.
要是你再试一试，你就会成功的。
(would表结果)
②If you tried again，you might succeed.
要是你再试一试，你可能会成功的。
(might表可能)
③If you tried again ，you could succeed.
要是你再试一试，你就能成功了。
(could表能力)
2.错综时间虚拟条件句：即条件从句与主句所指时间不一致，如从句指过去，而主句即指的是现在或将来，此时应根据具体的语境情况，结合上面提到的三种基本类型对时态作相应的调整
If it had rained last night, the ground would be wet now.
要是昨晚下过雨的话，现在地面就会是湿的。
If he were free today, we would sent him to Beijing.
如果他今天有空的话，我们就已经派他去北京。
3.If虚拟条件句的倒装形式：即把were, had, should置于句首，if可省略;。
e.g. Were I in school again (= If I were in school again), I would work harder.
如果我能再上一次学，我会学习得更努力。
Had you asked me, I would have told you. (=If you had asked me,…)
如果你问我，我会告诉你。
四．巩固检测
1.If I were you, I would take an umbrella (如果我是你，我会带把伞)
2.If I had gotten there earlier, I should/could met her.(如果我早点到，我就会见到她)
3.If there were a heavy snow next Sunday, we would not go skating. (如果下周日下大雪，我们就不能去滑冰了)
4.If it should snow tomorrow ，I would make a snowman . 把这个句子改成if条件句虚拟语气倒装句
Should it snow tomorrow，I would make a snowman.。
