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
时态类型主句从句例句
与现在事实相反主语+would/should/could/
might+ do
If+主语+did
(be动词用were)
1.If I were you, I should work hard、
2.The bedroom would be so
clean if I had time、
与过去事实相反主语+would/should/could/
might + have done
If+主语+had
done
1.If I had finished my homework,
I would have passed that test、
2、If I had left a little earlier, I would
have caught the train、
与将来事实相反主语+would/should/could/
might + do
①If+主语+did
(可能性一般)
1、If you came tomorrow, we would h
ave the meeting、①
②if+主语+shou ld +do(可能性最大)
③If+主语+were to + do(可能性最小) 2、If it were to rain tomorrow, the m eeting would be put off、③
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。
If he were free today, we would sent him to Beijing、
如果她今天有空的话,我们就已经派她去北京。
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,…)
如果您问我,我会告诉您。
四.巩固检测
1.If I were you, I would take an umbrella (如果我就是您,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、。
