英语虚拟语气语法归纳总结

虚拟语气:

表示说的话不是事实，不可能发生或者说可能性很小的情况，表达一种愿望、建议、假设。

条件状语从句中的用法

简单记法：

if were/did, would do

if had done, would have done

if were to do/should do, would do

举例：

If I were you, I would do no thi ng about it.

If you had taken your teacher ' s advice, you wouldn ' t have made such a mistake.

If it were to/ should rain tomorrow(表示降水率很低)，they wouldn ' go shopp ing.

附注：

虚拟语气，条件状从倒装

状语从句中，去掉if,提前were/ had/ should 女口：If I were you, I would give up.

—Were I you, I would give up

If you had take n the advice, you would have

—Had you take n the advice, you would have …

If the world should come to an end, .........

—Should the world come to an end ...............

另外，without, but for, otherwise构成的条件状语从句中，也有含蓄的虚拟语气

But for the popularization of electricity, we would lead a whole different life today. (popularization 普及，publicity 宣传)

Without your help, I would have failed.

We ll go earlier, otherwise we wouldn ' t(表示可能性小)

但其实，高中英语考试也常考：

错综虚拟语气条件句

即：假设条件状从发生的时间与所假设的谓语动词不一致，此时，主句和从句要根据各自的时间而定。

举例：

If our government had known better how to lay out the road construction, the traffic jam problem would not be so serious today.

（lay out规划、设计、安排、陈设、摆放…layout n.布局、规划）

二、特殊句式：

I wish my parents wouldn ' t punish me.

I wish I hadn' made such an irrevocable mistake. （irrevocable 不可撤销、不可以挽回的）

2. 「十个词」

一坚持：insist （表示坚持主张、认为，不表示坚持说）

二命令：order, comma nd

三建议：advise, propose, suggest （表示建议，不表示表明、显示、暗示）四要求：desire, dema nd, require, request （两R 两D）

这些动词后面的宾语从句要使用（should +） do的形式should可省略

例：

We suggested that Tom （should）have a rest.

It ' s suggested that the plan be carried out before long.

（before long,不久之后，Io ng before很久以前）

尝试翻译：他坚决要求我到场

同时，这些动词的名词形式构成的名词性从句（主语从句、表语从句、同位语）

也要用虚拟语气

order, advice, suggesti on, proposal, dema nd, request, desire.

例

It ' s an order that the sididj obey the rules in the army.

My suggesti on is that every one of us three fin ish one part of this project and the n we integrate them together. （integrate 整合）

3. would rather 宁愿

I would rather you had bee n to the movie in stead of me. Don' t come today, I would rather you came tomorrow.

4.部分As if/though句子好像、似乎

Tom told me this fairy tale in a manner as if it had happened for real yesterday.

5. If only ........... . 要是••就好了

从句中谓语动词形式：

If only she knew that it's I who sent the gift to her.

6. It ' s ( about/ high) time th是时候做.....

+ 1、过去式2、should do

It's time that you went to bed.

说到这里，补充两个句式：

It is the 1st (2nd /3rd) time that …have/ has done It was the 1st time that … had done ….

7. It ' s necessary/ strange/ natural/ important/essential that .....

从句动词用(should) do

It ' s essential that we master a foreign Ianguage when doing international trade and business.

(essential必要的、本质的、基本的…

8. 情态动词+have done

would have done 本来要做

could have done本能够做(却没做)

might have done 本来可能

should/ought to have done 本来应该做

shouldn ' t/ oughtn ' t to have(本i来不应该做

needn' t have done 本来不必要做

你本来不应该告诉她真相。
