3. 语法说明

学习和掌握虚拟语气的用法。

虚拟语气用来表示说话人的主观意愿或假想,所说的是一个条件,不一定是事实,或与事实相反。

1)在条件句中的应用

条件句可分为两类,一类为真实条件句,一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况,故采用虚拟语气。

A 真实条件句

真实条件句用于陈述语气,假设的情况可能发生。

时态关系

句型:条件从句 主句

一般现在时 shall / will + 动词原形

If he comes, he will bring his violin.

典型例题

The volleyball match will be put off if it_______.

A. will rain B. rains C. rained D. is rained

答案B。真实条件句主句为将来时,从句用一般现在时。

注意:

(1) 在真实条件句中,主句不能用be going to表示将来,该用shall, will.

(错) If you leave now, you are never going to regret it.

(对)If you leave now, you will never regret it.

(2) 表示真理时,主句谓语动词不用shall(will)+动词原形,而直接用一般现在时的动词形式。

B 非真实条件句

(1)时态:可表示过去、现在和将来的情况。其基本特点时态退后。

a. 同现在事实相反的假设。

句型:条件从句 主句

一般过去时 should(would)+动词原形

-If they were here, they would help you.

b. 表示与过去事实相反的假设。

句型:条件从句 主句

过去完成式 should(would)have+过去分词

-If he had come yesterday, I should have told him about it.

含义:He did not come yesterday, so I did not tell him about it.

c. 表示对将来的假想

句型: 条件从句 主句

一般过去时

were+不定式 should(would)+动词原形

should+动词原形

If you succeeded, everything would be all right.

If you should succeed, everything would be all right.

If you were to succeed, everything would be all right

(2) 混合条件句

主句与从句的动作发生在不同的时间,这时主,从句谓语动词虚拟语气形式因时间不同而不同,这叫做混合条件句。

-If you had asked him yesterday, you would know what to do now.

(从句与过去事实相反,主句与现在事实相反。)

-If it had rained last night(过去),it would be very cold today(现在).

(3)虚拟条件句的倒装

虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略,再把were, should 或had 移到从句句首,实行倒装。

Were they here now, they could help us.

=If they were here now, they could help us.

Had you come earlier, you would have met him.

=If you had come earlier, you would have met him.

Should it rain, the crops would be saved.

=Were it to rain, the crops would be saved.

注意:

在虚拟语气的从句中,动词 ‘be’的过去时态一律用 “were”。

If I were you, I would go to look for him. 如果我是你,就会去找他。

If he were here, everything would be all right.

典型例题

_______ to do the work, I should do it some other day.

A. If were I B. I were C. Were I D. Was I

答案C. 在虚拟条件状语中如果有were, should, had这三个词,通常将if省略,主语提前,变成were, should, had+主语的形式。但要注意,在虚拟条件状语从句中,省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说Were I not to do. ,而不能Weren’t I to go.

(4)特殊的虚拟语气词:should

① suggest/order/command/propose/demand/insist/require/ request… + that … (should) do

② the suggestion that … (should) do

③ This suggestion is that …(should) do

④ It is demanded/suggested/ordered/required/insisted … + that … (should) do

⑤ It is necessary/important/natural/strange… + that … (should) do

⑥ It is a pity/ a shame, no wonder… + that … (should) do

在宾语从句中的应用

在表示命令、建议、要求等一类动词后面的从句中。

order, suggest, insist … + (should) do

---I suggest that we(should)hold a meeting next week.

---He insisted that he(should)be sent there.

注意:如suggest, insist不表示“建议”或“坚持要某人做某事时”,即它们用作 “暗示、表明”、“坚持认为”时,宾语从句用陈述语气。

---The guard at the gate insisted that everybody obey the rules.

---Your pale face suggests that you are ill.

---I insisted that you were wrong.

在表语从句,同位语从句中的应用

在suggestion, proposal, idea, plan, order, advice 等名词后面的表语从句、同位语从句中要用虚拟语气,即(should)+动词原形。

-My idea is that we (should)get more people to attend the conference.

-I make a proposal that we (should) hold a meeting next week.

(5)wish的用法

用于wish 后面的从句,表示与事实相反的情况,或表示将来不太可能实现的愿望。其宾语从句的动词形式为:

wish + (that) … did/were …(现在时:从句与主句动作同时发生)

wish + (that) … had done …(过去时:从句动作先于主句动作)

wish + (that) … would/could do (将来时:从句动作于主句动作之后)

I wish I were as tall as you. 我希望和你一样高。

He wished he hadn’t said that. 他希望他没讲那样的话。

I wish it would rain tomorrow. 我希望明天下雨就好了。

(6) if only

if only 表示“如果就好了”。

-If only the alarm clock had rung. 当时闹钟响了,就好了。

if only也可用于陈述语气。

-If only he comes early. 但愿他早点回来了。

***only if 表示“只有”:

-I wake up only if the alarm clock rings. 只有闹钟响了,我才会醒。

(7)It is (high) time that …

It is (high) time that 后面的从句谓语动词要用过去式或用should加动词原形,但should不可省略。

It is time that the children went to bed.

It is high time that the children should go to bed.

(8) need

didn’t need to do表示:过去不必做某事,事实上也没做。

needn’t have done表示:过去不必做某事,但事实上做了。

John went to the station in his car to meet Mary, so she didn’t need to walk back home.

John went to the station in his car to meet Mary, so she needn’t have walk back home.

(9) 虚拟语气在其他状语从句中的用法

在as if引导的状语从句中,用过去式表示与现在事实不符,用过去完成式表示与过去事实不符;在so that,in order that引导的状语从句中,常用should/would/could/might+动词原形来表示虚拟语气。如:

They talked as if they had been friends for years.

She stayed at home for a few days so that she could take care of her mother.

(10)would rather sb. did/had done …

(would rather do)

---I’d rather stay at home than go out.

---He’d rather you came on Friday.
