高中英语虚拟语气讲解及练习

虚拟条件句就是对现实条件的一种虚拟假设,所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。根据时间的不同,虚拟条件句可分为三种,即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句及与将来事实相反的虚拟条件句。具体情况请看下表:

条件状语从句 主 句

与过去事实相反 had + 过去分词 should /would/could/might + have

+ 过去分词

与现在事实相反 一般过去时(be用were) would/should/could/might + 动词原形

与将来事实相反 一般过去时或should(were to) + 动词原形 would/should/could/might + 动词原形

例句:

(1)表示与现在事实相反

If I had enough money now, I would lend it to you.

(2)表示与过去事实相反

If he had taken your advice, he wouldn’t have made such a bad mistake.

(3)表示与将来事实相反

I would go shopping with you if it were to be Sunday tomorrow.

1. 虚拟条件句的倒装

在虚拟条件句中,为了强调所假设条件的虚拟性,或突出说话人的一种主观愿望,虚拟条件句可用倒装结构。虚拟条件句的倒装是通过去掉if,把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。例如:

Had I been(= If I had been ) in that situation, I would not have let the thief

escape away with so much money.

Should there be (= If there should be) a drought, what should we do at that

time ?

2. 错综时间条件句

有时条件从句的动作和主句的动作发生的时间并不一致,这时谓语动词的形式应根据它所要表示的具体时间来确定。例如:

If we hadn’t been working hard in the past few years ,things wouldn’t be going

so smoothly.

3. 含蓄条件句

有时假设的情况并不以条件从句的形式表现出来,而是通过某个介词或介词短语(如:with,otherwise,without,but for,in that position)、上下文或其它方式表现出来。这种句子称为含蓄条件句。例如:

But for the help from you , I would not have had the chance to go to college.

二、虚拟语气在某些从句中的运用

在某些词或短语后接的从句中要使用虚拟语气,表示愿望、建议或命令等。根据虚拟语气的形式不同,虚拟语气可以分为“should类”和“过去时态类”。

(一)should类 这一类的虚拟语气是通过从句中的谓语动词使用“should +动词原形”体现出来的,should可以省略。其具体运用体现在:

1. 在suggest , order, demand , propose, command, request, desire,insist等表示建议、命令、要求、意见的动词后接的宾语从句中要使用虚拟语气。

如:He suggests that she should leave the house at once.

The leader ordered that the task(should) be finished as soon as possible.

He proposed that we (should)deal with the problem by the view of

development.

2. 与suggest,order,demand,propose,command,request,desire,insist等动词相对应的名词suggestion,order,demand,proposal等后的表语从句或同位语从句中要使用虚拟语气。如:The general sent the order that the battle(should)be held on until the complete failure of the enemy.

My proposal is that we(should) set a deadline for handing in the plan.

3. 在It is/was suggested (ordered,demanded,proposed,etc.)结构以及necessary,essential,important,strange,natural等形容词后的主语从句中要使用虚拟语气。如:

It’s requested that we (should)keep the stability of the society for the people’s

peaceful life.

It is necessary that the badly wounded man(should) be treated immediately.

(二)过去时态类

英语中,还有一些词或短语后接的从句或句子,也要使用虚拟语气,虚拟语气是通过句中的谓语使用过去的某种时态(如:一般过去时、过去完成时等)来体现的。

1. wish,would rather 后的宾语从句。如:

He wished he had never been involved in such affairs.

I would rather you could teach me again.

2. as if,as though引导的从句。如:

The little boy knows so many things as if he was a man.

He acted as usual as though nothing had happened.

3. 由if only (要是……,那该多好啊!)引导的惊叹句。如:

If only I had passed the test!

If only it stopped raining!

4. It is(about/high) time 后的定语从句。如:

It is time we went out for a walk.

It was high time they had begun to prepare the experiment.

三、虚拟语气的其它用法

在英语中,一些表示建议、请求、劝告、愿望、祈祷、祝福或诅咒的句子,也需要使用虚拟语气。如:

Would you mind smoking here?

May you be lucky!

Long live the people of China!

God save me.

虚拟语气练习题

1.If we __________ a ticket earlier, we would be watching the film now.

A.have booked B.booked

C.book D.had booked

【答案】D

【解析】

【详解】

考查虚拟语气。句意:如果我们早订了一张票,我们现在就会看这部电影。此处是if引导的虚拟语气,与过去的事实相反,所以从句要用过去完成时态,故选D。

【点睛】

虚拟语气在 if 引导的条件句中的用法:

(一)表示与现在事实相反的情况 从句:if + 主语+ 动词的过去式(be 用 were) + …… 主句:主语+ would (should, could , might) + 动词原形+ …… 例:1. If he hurried, he could catch the first

bus. 他要是快点能够赶上头班公共汽车。(可是他不着急) 2.If it weren’t for your help, we

would get into trouble. 如果没有你们的帮助,我们就会陷入困境。 (而事实上得到了你 们的帮助)

(二)与过去事实相反的情况,句子结构为:从句:if +主语 +had +动词完成式 +其他,主句:主语 +would have +动词的完成式 +其他。1)If he had come here yesterday, he would

have seen his ol d friend.假如他昨天来这儿的话,就会看见他的老朋友。 2)If it had rained

yesterday, we would have stayed at home. (如果昨天下雨的话,我们就会留在家里。)

(三)与将来事实相反的情况,句子结构:从句:if +主语 +should +动词原形 +其他,主句:主语+would +动词原形+其他 If I should have enough money ,I would buy a book.

2.He ______ busy yesterday, or he ______ you with your experiment.

A.was; had helped B.was, would have helped

C.had been; would have D.were; would have helped

【答案】B

【解析】

【详解】

试题分析:本题实际上考察的是or(否则,要不然)引导的含蓄的虚拟条件句。前面句中含有yesterday这个过去时的时间状语,故使用过去时即可。Or后面的句中要使用与过去事实相反的虚拟语气would have done的形式。句义:昨天他很忙,要不然他就会帮助你做实验了。故B正确。

考点:考察虚拟语气

3.It is requested that the reporter ________ to blame for the wrong report.

A.referring to B.referring to as

C.referred to be D.referred to being
