一、虚拟语气在非条件句中
虚拟条件句
与现在
事实相
反的假
设
与过去
相反的
假设
与将来
相反的
假设
If+主语+动词的过去式
(动词be用were)
If+主语+had +过去分词
1、If+主语+were to+ 动词原形
2、If+主语+should +动词原形
主句
主语+should,
would,might,
could+动词原形
主语+should,
would,might, could
+have +过去分词
主语+should, would,
might, could+动词原形
eg:If I had time, I would attend the meeting.
If he had hurried ,he could have caught the train.
If I were to go abroad ,I would go to America.
More practice:
如果我是你,我就会努力学习.
If I were you, I would work harder at my lessons.
如果我知道他的电话号码,我就给他打电话了.
If I had known his telephone number, I would
have called him.
如果明天下雨的话,我们会取消比赛.
If it should \were to rain, we would call off the
match.
使用虚拟条件句要注意的几点:
1. 当条件状语从句表示的行为和主句表示的行为
所发生的时间不一致时,被称为:”错综时间条件句
“,动词的形式要根据它所表示的时间作出相应的调
整.
如果你听我的建议,你现在就会痊愈了.
If you had followed my advice , you would be
better now.
如果你努力学习的话,你现在就会是大学生
了.
If you had studied hard before, you would be a
college student now.
2.省略句
在条件句中,可省略 if,把were ,had, should 提到句首,
变为倒装句式.
If I were at school again, I would study harder.
Were I at school again, I would study harder.
If you had come earlier, you would have met him.
Had you come earlier, you would have met him.
If it should rain tomorrow, we would not go climbing.
Should it rain tomorrow, we would not go climbing.
注意:若省略的条件句中的谓语动词是否定式,不能用动词
的缩略形式.如我们可以说 Were it not for expense, I
would go abroad now. 不可以说 Weren’t it for the
expense,…
3、用介词短语代替条件状语从句.常用的介词有
with, without, but for 等。如:
What would you do with a million dollars?
(=If you had a million dollars)?
We could not have finished the work ahead of
time without your help.
(=if we hadn’t got your help).
But for the rain (=If it hadn’t been for the rain),
we would have finished the work.
4、
含蓄条件句。
有时为了表达的需要,在虚拟语气中并不是总是
出现if引导的条件句,而是通过其他手段来代替条
件句。
I was ill that day. Otherwise , I would have taken
part in the sports meet.(副词)
He telephoned to inform me of your birthday, or I
would have known nothing about it.(连词)
I might have given you more help, but I was too
busy.(连词)
Everything taken into consideration, they would
have raised their output quickly.(独立主格)
I would buy the book, but I have not enough
money.
I would have bought the book, but I didn’t have
enough money.
我会买那本书的,但我现在没有钱.
我会买那本书的,但我当时没有钱.
I haven’t enough money, otherwise I would buy
the book.
I didn’t have enough money, otherwise I would
have bought the book.
我没有足够的钱.否则我会买那本书的.
二、虚拟语气在名词从句中的运用
用于宾语从句

现的愿望。其谓语动词形式为:
表现在
过去时
表过去
过去完成时
表将来
would, might, could+动词原形
I wish (that) I were a bird.
I wish (that) I had seen the film last night.
I wish (that) I would\could go. 但愿我能去.
2.用于表示命令、建议、要求等一类词后面的宾语从句。

insist, order, command, suggest, advise,
propose, require, request, demand, desire etc.
We suggested that the meeting (should) be put off.

our work.
那个人坚持说他没有偷钱.
The man insisted that he had never stolen the money.
用于主语从句中
1.It is necessary/important/strange/natural/impossible /

原形,should可以省略。

that…
