if条件句的虚拟语气与倒装句课件

虚拟语气与倒装句(教师版)什么就是虚拟语气(subjunctive mood)?If I were you, I would not do like this、要我就是您,我就不会这样做I wish I became a millionaire、要就是我就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就是真实发生,只就是一种假设,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: 那就是不就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,表示的假设就是有可能发生的,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,表示的就是一种假象,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、要就是您再试一试,您就会成功的。

(would表结果)②If you tried again, you might succeed、要就是您再试一试,您可能会成功的。

(might表可能)③If you tried again ,you could succeed、要就是您再试一试,您就能成功了。

(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,而主句即指的就是现在或将来,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、要就是昨晚下过雨的话,现在地面就会就是湿的。

1. 通过本课的学习，能够全面掌握if虚拟条件句的几种较复杂和特殊的情况。

2. 通过本课的学习，能够准确运用错综时间虚拟条件句、虚拟倒装句和含蓄虚拟语气等。

重点：掌握错综时间的虚拟语气以及虚拟倒装句的具体规则。

难点：能够在解题过程中熟练识别和运用含蓄虚拟条件句。

近几年高考对于虚拟语气的考查主要集中在语法填空和书面表达中，语法填空涉及动词提示词的填空中多次出现对虚拟语气的考查，考查难度不大。

一、错综时间虚拟条件句：有些条件句中主句的谓语和从句的谓语表示的动作在时间上并不一致，这类句子称为错综时间条件句。

当虚拟条件状语从句与主句所虚拟的时间不一致（如从句虚拟过去，而主句虚拟现在或将来）时，主句、从句中谓语动词的形式须依据各自所表示的时间，综合if虚拟条件句的三种基本类型进行调整。

If you’d listened to me, you wouldn’t be in such trouble now.如果你听了我的话，你现在就不会有这样的麻烦了。

（过去→现在）If I were you, I wouldn’t have missed the movie last night.如果我是你，我就不会错过昨晚那部电影。

（现在→过去）If they had left home early, they would arrive in half an hour.要是他们早离开家的话，再过半个小时就该到了。

（过去→将来）If Monica should arrive today, she must have started three days ago.如果莫尼卡今天到达的话，那她一定是在三天前就动身了。

（将来→过去）If you had studied hard last year, you would be a college student now.要是你去年努力学习的话，现在你就是个大学生了。

If it had rained last night, the ground would be wet now.如果昨天下雨了的话，地面现在就应该是湿的。

If 条件从句（虚拟语气）If 条件句可分为真实条件句和非真实条件句。

一．真实条件句：用于假设可能发生但不确定的事情。

If you don’t hurry, you will be late for school. (假设可能发生的情况)If he comes here, I will go shopping with him. (假设可能发生的情况)二．非真实条件句：用于假设不太可能发生或与事实相反的事，须用虚拟语气。

(虚拟条件句，谓语永远是过去)If I were you, I would tell him the truth.(事实是我不可能是你)If we never slept, we all would get better grades.(事实是我们不可能不睡觉)从句通常分为三种情况：与现在事实相反，与过去事实相反，与将来事实相反。

1.与现在事实相反；从句：if+主语+did. (be动词都用were)主句：主语+should/would/could/might+do. （我是迈克）If I were rich, I shall/would not work. (事实是我现在没钱)If he had time, he would/might help you.If you knew the truth, could you tell me?If I were the principal, I would plant more trees in our school.If he were here, everyone would be all right.If I had enough money, I would buy a new car.2.与过去事实相反；从句：if+主语+had+done.主句：主语+should/would/could/might+have+done. （我是迈克）If the police had caught the thieves, they would have put them in prison.If you had work harder, you might have succeeded.If I had got earlier, I would not have been late for school.If it had not been for your help yesterday, I could not have caught the bus.If the weather had been nice yesterday, we would have gone for a picnic.3.与将来事实相反；从句：①if+主语+should+do.②if+主语+did. (be动词都用were)③if+主语+were to do.主句：主语+should/would/could/might+be/do. （我是迈克）If he should go to the university, he would be very proud.If it were to snow tomorrow, we would make snowmen.If we had less homework than usual, we would play games.If he succeeded/should succeed/were to succeed, everything would be all right.If you should fail, what would you do?三．省略if的虚拟语气（倒装句）如果if从句中含有were/had/should (我很帅)，则可以把if 省略，把这三个词放置句首形成倒装句。
