思维导图大纲

1、与现在事实相反得主观假设

条件从句

一般现在时改为一般过去时

主句

should/would/could/might +动注: be 动词一律改为were

2、与过去事实相反得主观假设

条件从句

一般过去时改为过去完成时

主句

should/would/could/migh/thave+过去分词

3、与将来事实相反得主观假设

条件从句

一般过去时

注: be 动词一律改为were词原形

should+动词原形

were + to do sth

主句

should/would/could/might +动

混合条件句

主句与条件从句所发生得时间点不一致,这个时候就需要根据各自得时态进行倒退来做相应修改

例句:If you had finished your homework by yourself yesterday (过去)

you would not copy other's answers in a hurry (现在)

虚拟语气得倒装

如果从句中有were, should, had, 则需要倒装

倒装方法:将if省略，再把were, should, had挪到从句得句首，如果从句中没有were, should, had, 则不能省略if,也不可倒装

原句: If you should make great progress in the near future, you should be grateful to your teachers

倒装: Should you make great progress in the near future, you shouldbe grateful to your teachers

(2) It isnecessary/important/indispensable, etc、( 带有主观色彩得形容词) + that sb (should) do sth

5、虚拟语气特殊句型

It is high (high 可省略) time that ...该就....得时候了“that ...”从句动词可以用

(1)过去时

例句:It is (high) time that we should draw up a contract
