虚拟语气的用法及专项练习题
Book6 Module5语法聚焦
——
虚拟语气表示一种假设的情况,或一种主观的愿望,即动词所表示的动作或状态并非事实,
或不可能实现。英语虚拟语气的形式有下列几种:
一.虚拟语气用于条件状语从句
注意:
主句中的should通常用于第一人称,would可用于任何人称,同时也可根据意思用情态动
词c
ould,might等代替should,would。
1.与现在事实相反
连接词
If
条件从句
1).动词过去式(或were)
2).助动词(过去式)+动词原形
结果从句
ShouldWouldCouldmight+动词原
形
If had the
time, John would make a trip to China to see the
Great Wall.
If I were you, I would give up
drinking immediately.
2.与过去事实相反
连接词
If
条件从句
had+过去分词
结果从句
ShouldWouldCouldmight + have+过去分词
If I’d
known that it was going to rain, I would never
have gone for a walk in the country.
3.与将来事实相反
连接词 条件从句
1. should+动词原形
If
2.
动词过去式
3、were to+动词原形
If it were toshould
rain tomorrow,the meeting would be put off.
If you went there next time, you would see
what I mean.
4.错综时间虚拟语气
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,动词的形式要根据它
所表示的时间来调整。例如:
ShouldWouldcouldmight+动词原形
结果从句
If I were you, I would have gone
home.(
从句说的是现在,主句指的是过去。
)
If you had
followed the doctor's advice,you would be quite
all right now.(从句说的是过去,主句指
的是现在。)
If the
weather had been more favorable ,the crops would
be growing still better.
其它状语从句
1. 方式状语as
if(as though)
如果从句表示与现在事实相反,谓语动词用一般过去时;表示与过去事实
相反,谓语动词用
过去分词表示与将来事实相反,谓语动词用动词原形。例如:
He
looks at me as if I were mad.
He spoke
English so fluently as if he had studied English
in England.
但as if(as though)后的从句也常用陈述语气,这是因为从
句中的情况往往是可能发生的或可能
被设想为真实的。例如: It looks as if our
side is going to win.
2. 目的状语in order that,so
that 从句谓语动词用动词原形。例如:
She listened carefully
in order that she might discover exactly what he
wanted.
3. 连词引导的条件状语从句:
in case , unless
,supposing ,providing,on condition
that从句谓语动词用(should)或
动词原形。
4. 连词引导的步状语从句
lest ,for fear that等
We hid behind some bushes
for fear that passer-by should see us.
二.虚拟语气用于宾语从句
t, advise
等动词之后宾语从句须用虚拟语气,其句子结构如下:
要求:ask demand require
request beg plead insist pray urge
建议:suggest
advise propose recommend move
命令、决定:order
command decide determine resolve
其它:consent
deserve desire intend maintain prefer等后面的宾语从句中
+that…(should )+动词原形
注意:在此结构中that不可省略;should省不省均可。
He suggested
that they (should ) stop smoking.
They
demanded that the black people should be treated
as well as white people.
如果that
引导的从句所表达的内容是事实,也可用陈述语气。
He insists that
he is right. 注意:insist作力言、强调解时,宾语从句不用虚拟语气。只有当
insist作坚持(应该)解时,宾语从句才用虚拟语气。例如:
Mike insisted
that he had never stolen anything.
back.
2.宾语从句表示不能实现的愿望,汉语可译为可惜……、就好了、悔不
该……、但愿……等。表示现在
不能实现的愿望,从句的谓语动词用过去式;表示将来不能
实现的愿望,用动词原形表示过去不能实现的
愿望,用过去分词或
过去分词。例如:
wish的用法
1). 与现在事实相反
:动词过去式或were
I wish we could go to the seaside
today.
I wish I were a pop singer. (=I am
sorry I am not a pop singer..)
2).与过去事实相反 :
主语+wish(that)+主语 + 动词过去完成式
We wish we had
arrived there two hours earlier.
I wish I had
never stopped teaching. (=I am sorry I stopped
teaching.)
3).与将来事实相反 :助动词过去式+动词原形
I wish
they’d let us get some sleep.
注意:wish与hope接宾语从
句的区别在于:hope表示一般可以实现的希望,宾语从句用陈
述语气。wish表示很难或不大可能
实现的希望,宾语从句用虚拟语气。试比较:
(1) We hope they will
come,(We don’t know if they can come.)
(2) We
wish they could come,(We know they are not
coming.)
3..虚拟语气在would ratherwould soonerwould
just as soon后接从句:
I'd rather you paid me
now.(从句用过去时指现在)
I would rather they came
tomorrow.(从句用过去时指将来)
I'd rather she hadn't
done that.(从句用过去完成时指过去)(此句中的would可看作是表愿望的实
义动词)
三.虚拟语气用于主语从句
在主语从句中,谓语动词的虚拟语气结构用动词原形的结构,表示
惊奇、不相信、惋惜、
理应如此等。例如:
It is necessary(
appropriate crucial desirabledreadful
essentialimportant improper
incredible
indispensable insistent natural preferable
possible probable proper right
I insisted
that you give me my money
.significant
surprising strange tragic urgent vital wrong
etc.)that we should clean the room
every day.
It was a pity(a shame,no wonder,etc.)that you
should be so careless.
It will be desired(sug
gested,decided,ordered,requested,proposed,etc.)tha
t she should finish her
homework this
afternoon.
a 在上述三种主语从句中,should意为应该、竟然可以省去,但不可换
用would。主句所用
动词的时态不限。
注意:这种从句表示的是事实。如果说话人对这种
事实表示惊奇,就可用虚拟语气。反之,如果
不表示惊奇,that从句也可用陈述语气。例如:
It is strange that he did not come yesterday.
四.虚拟语气用于表语从句、同位语从句
要求:demand requirement
request motion pray insistence
建议:suggestion
advice proposal recommendation motion
命令、决定:order command decision determination
resolution
其它:plan desire idea necessity prefe
rence等名词的表语从句和同位语从句,其谓语动词要
用虚拟语气的结构动词原形。例如:
We all agreed to his suggestion that
we(should)go to Beijing for sightseeing.
My
idea is that he (should)do exercises first.
五、虚拟语气的几种特殊用法
1.省掉if的条件从句倒装结构:(should,
had, were)
Had you asked me, I would have told
you. (=If you had asked me,…)
Were I you, I
would be back home. (= If I were you, …)
Should I know it, I would tell you. (= If I
should know it, …)
2.有时虚拟条件不用条件从句而用不定式、分词、介词、名
词、连接词或定语从句来表示,
如:A true friend would not do
such a thing. (=If he were a true friend, he...)
Without water, we would not live. (=If there
were no water,…)
But for your help, I
couldn’t have finished it.(=If you hadn’t helped
me,…)
3. 虚拟语气用于定语从句:It’s (high) time
that…+动词过去式或should+动词原形,
(should不
能省略,be用were)来表示,意为现在)该……。如:
It’s
time (that) you had a hair cut. It’s high time
(that) we took some action.
It is a pity that
you can't swim.
4.虚拟语气用于if only引导的感叹句:
If only I had taken his
advice.我要是听他的话就好了。 If only I were a
bird!我如果是一只鸟就
好了。
5.虚拟语气用于简单句
1)表示说话人谦虚、客气、有礼貌,使语气委婉,常出现在日常会话中。例如:It would
be better for
you not to stay up too late.
Would you be kind enough to open the door?
2)用于一些习惯表达法中。例如:
Would you like a cup of
tea. You had better go now.
3)用动词原形表示祝愿、但愿。may须置于句首。例如:
May you be
happy!
6.含蓄条件句
在某些虚拟语气结构中没有if条件句,虚拟条件是用其它
形式表示出来,这种现象在语法上称
为含蓄条件句。含蓄条件具体分为以下几种情况:
1)通过动词不定式短语表示条件。例如:
You would be a fool to
refuse his offer.
要是你拒绝他的建议,就太傻了。
(=If
you should refuse his offer,you would be a
fool.)
May you succeed!
2)通过介词短语表达条件。例如:
But for the storm I would have arrived much
earlier. (=If it had not been for the storm...)
要不是那场暴雨,我早就到达了。
Without air, there would
be no living things. I would not have succeeded
but for your help.
3)通过连词otherwise,or,but,that
,though,once等表达条件。例如:
She came to town
yesterday,otherwiseor I would not have met her.
昨天她到城里来了,不然我就不会遇见她了。(otherwiseor=if she hadn't
come)
I would have attended the meeting,but
I have been too busy. (=...if I had not been too
busy)
我本来要参加会议的,只是太忙了。
4)通过Were it not
for...或Had it not been
for...等句式表达条件。意为如果当时没有……表示
同过去事实相反的假设。例如:
Were it not for(=If it were not for) the
leadership of the Party,we could not live a happy
life.
要不是党的领导,我们不可能过幸福生活。(与现在事实相反)
Had it
not been for(=If it had not been for) the
leadership of the Party,we should have failed.
若不是有党的领导,我们早就失败了。(与过去事实相反)
5)通过分词短语表达条件。例如:
Given more
attention,the trees could have grown
better.倘若给予更多的关心,这些树本来可以生
长得更好的。(=If they had
been given more attention...)
6)无词句暗示条件。例如:
Such mistakes could have been
avoided.这种错误本来可以避免的。
(暗含条件从句if we had been
more careful)
It was so quiet,you could have
heard a pin drop.是那样的安静,掉根针你都听得见。
(暗含条件从句if it
had dropped to the ground)
