初中英语虚拟语气讲练(附答案)
初中英语虚拟语气讲解及练习
英语中的语气分为陈述语气、祈使语气、虚拟语气三类。
虚拟语气表示说话人的主观愿望或假想,所说的是一个条件,不一定是事实,或与事实相反。条件句可分为两类,一类为真实条件句,一类为非真实条件句。陈珊妮情歌
非真实条件句表示的是假设的或实际可能性不大的情况,故采用虚拟语气。
如果假设的情况可能发生,是真实条件句,这种情况下谓语用陈述语气。如:Iftime permits, we'll go fishing together.如果时间允许,我们就一起去钓鱼。
如果假设的情况是不存在的或不大可能发生的,则是虚拟条件句。如:If youhad come yesterday, you would have met that famous professor.如果你昨天来,你就会见到那位著名的教授了。(隐含的事实是:你昨天没来,也没见到那位著名教授)。
虚拟语气的基本形式和用法在含有虚拟条件句的复合句中,主从句的谓语都要用虚拟语气。
1.含有条件状语从句的复合句
wish(would rather)+宾语从句
suggest(…)+宾语从句
2.主语从句It is + adj./p.p/n.+ that+ S+ (should) +do
表语从句S+is that +s + (should) +do
同位语从句S+that +s +(should) +do
3.定语从句It is (high) time that + S + did
用过去式表现在情况
1.时态后退型用过去完成式表过去
两种形式用过去将来表将来
2. should+动词原形型
内容详述
I.含有条件状语从句的复合句(以do为例;S=主语)
时间条件状语从句主句
与现在事实相反的假设If+S+did…S+would/should/could/might+do…与过去事实相反的假
设If +S+haddone…S+would/should/could/might+havedone…
与将来事实相反的假设did…
If+S should do
were to do
S+would/should/could/might+do…
注意事项:
1.倒装句。如果条件句中含有功能词had,should,were时,可以省去If,把功能词提前,构成倒装句。
2.错综条件句。若条件句和主句动作不存在同一个时间,则谓语形式应根据具体情况而定。
3.If there weren't/had not been+…=without…
4.If it were notfor…/If it hadn't beenfor…=butfor…
5.otherwise+虚拟语气的句子
6.虚拟语气的句子,but+陈述事实的句子蔬菜市场
