虚拟语气（注意时态和所用规则）

一般原则

现在： if+主+动词过去式（be动词用were） 主+should/could/would/might+do

过去： if+主+had + done 主+should/could/would/might+have/has + done

将来： if+主+动词过去式

If+主+were to do 主+should/could/would/might+do

If+主+should do

出现with、without、but for、otherwise、ever if 、ever though………用法与一般原则一样

Wish原则

虚拟的动作相比wish是同时时，虚拟部分用-----------过去式

过去 -----------过去完成时

未来 -----------could/would do

例：I wish ………………………………

If only =I wish

学过倒装的，可以回顾一下if的倒装形式

区别 ： If only 与 only if

（if） (只有…才…)

意思雷同首字母

Would rather原则

对现在虚拟-------用过去式

过去 -------用过去完成式

将来 -------用过去式

例：I’d rather that………………

As if /as though 原则

虚拟语气知识点简述

1、含义：用来表示说的话并不是事实，而是一种愿望或者是一种与事实相反的假设。通常结构为if+从句，主句。

2、规则变化：

表示与现在事实相反。 从句： if+主语+动词的过去式/was，were

主句：主语+should,would,might,could+动词原形

表示与过去事实相反 从句： if+主语+had done(过去分词)

主句：主语+should,would,might,could+have done

表示与将来事实相反

从句：if +主语+动词过去式/were to+动词原形/should+动词原形

主句：主语+should,would,might,could+动词原形

省略if的虚拟语气，从句中有were，had，should等词语，省略if，将were，had，should提到句首。

3、混合虚拟条件句，不同时间的虚拟，各自遵守各自的规则。

If you had followed the doctor’s advice, you would be quite all right now.

从句对过去虚拟，所以用had done, 主句对现在虚拟，所以用would+动词原形

4、表示坚持，命令，建议或暗示的含义时，使用should+动词原形。should可以省略。此类经常考，常见单词有insist, suggest, require, demand 等。譬如：His smile suggested that he was satisfied with our work.他的笑容暗示他对我们的工作很满意。该类句式也可发生变化，甚至是词性变为名词，但意思属该类，也需要用should+动词原形的结构。

高考英语语法专题讲解-虚拟语气

1 虚拟条件句：

1.1 与现在事实不一致，其句型为：

If +主语＋did，主语＋should（could, would, 或might）＋do.

如：

If I were you, I would study hard. （可倒装）

If it rained, I would not be here now.

1.2 与过去事实不一致，句型为：

If +主语＋had＋done，主语＋should（could, would, 或might）＋have＋done.

如：

If the doctor had come last night, the boy would have been saved. （可倒装）

比较这一句：

If the doctor had come last night, the boy would be saved.

->（混合虚拟:要求根据语境判断！）

1.3 将来事实不一致，句型为：

If shouldwere to主语＋＋do，主语＋should（could ，would, 或might）＋do.

如：

If it should rain tomorrow, we would stay at home.（可倒装）

If I were to go to the moon one day, I could see it with my own eyes.（可倒装）

If you missed the film to night, you would feel sorry.（混合虚拟）

P.S:

1、If条件句中绝对不可出现“would”。

2、根据句中的时间状语，有时可能出现“混合虚拟”的情况，即主句可能是现在的情况，条件句也许是发生在过去的情况，但都是遵守上述句型。
