0910AW SPECTACULAR 之【SU & SY SO】第四期——虚拟语气
一、介绍:虚拟语气是英文中一特殊的语言现象,主要用于表达与事实相反或者对尚未发生的事情进行假设的陈述,常表达强烈愿望、遗憾、感慨、后悔、责备、规劝等语义。
可大致分为三类:
1、对现在事实的虚拟
基本形式:If + were /did等过去式…, …would /could /should /might + do
例句:
If I were a bird, I would fly to the moon.
If she knew who you are, she would go out of joy.
If they were here, they would help you.
2、对过去事实的虚拟
基本形式:If + had done…, …would /could / should /might + have done
例句:If she had been warned earlier, she wouldn’t have broken the rules.
(事实上:She was not warned earlier and she broke the rules.)
If it hadn’t rained, the match would have seemed more fascinating.
(事实上:It rained and the match was less fascinating.)
If she had worked harder, she would have succeeded.
The rice would not have been burnt if you had been more careful.
If my lawyer had been here last Saturday, he would have prevented me from going.
If he had come yesterday, I should / would have told him about it.
含义:He did not come yesterday, so I did not tell him about it.
If he had not been ill and missed many classes, he would have made greater progress.
含义: He was ill and missed many lessons, so he did not make greater progress.
3、对将来事实的虚拟
基本形式:If + should do…, …would /could /should /might + do; 意思类似汉语中的“万一”
If + were+ 不定式…, …would+ do;
Should+ 动词原形
例句:If he should forget the date, I might teach him a good lesson.
(事实上:他不大可能忘记那个日期)
If it should snow this afternoon, we could make a snowman.
(事实上不大可能会下雪)
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.
其他一些重要的语言点:
4、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。
例句: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.
Should my car fail, I would have to return home on foot. = If my car should fail, I would have to return home on foot.
Had the letter been sent out, it would have ruined our friendship. = If the letter had been sent out, it would have ruined our friendship.
5、wish的用法
1)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:
(比真实的提前一格)
| 真实状况
| wish后
| 从句动作先于主句动词动作(be的过去式为were)
| 现在时
| 过去时
| 从句动作与主句动作同时发生(had+过去分词)
| 过去时
| 过去完成时
| 将来不大可能实现的愿望
| 将来时
| would/could+动词原形
|
例句:
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。
2)Wish to do表达法。
例句: Wish sb / sth to do
I wish to see the manager. = I want to see the manager.
I wish the manager to be informed at once. (= I want the manager to be informed at once.)
6、比较if only与only if:
only if表示"只有";if only则表示"如果……就好了"。If only也可用于陈述语气。
例句:I wake up only if the alarm clock rings. 只有闹钟响了,我才会醒。
If only the alarm clock had rung.(与过去事实相反)当时闹钟响了,就好了。
If only he comes early. 但愿他早点回来。
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。
例句:It is time that the children went to bed.
It is high time that the children should go to bed.
这个忘了
8、need "不必做"和"本不该做"
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。
例句:John went to the station with the car to meet Mary, so she didn't need to walk back home. 约翰开车去车站接玛丽,所以她不必步行回家了。
John went to the station with the car to meet Mary, so she needn't have walked back home. 约翰开车去车站接玛丽,所以她本不必步行回家了。 (Mary步行回家,没有遇上John的车。)
9、as, 或者whether…or…谓语多用be的原形,引导让步虚拟从句,这种用法通常采用倒装结构。
例句:Church as we use the word refers to all religious institutions, be they Christian, Islamic, Buddhist, Jewish, and so on.
不管是基督教,还是伊斯兰教,佛教和犹太教,我们都用church来指代宗教场所。
The business of each day, be it selling goods or shipping them, went quite smoothly.
注意1:部分动词的宾语从句中需用虚拟语气,形式为should do, 其中should常被省略。
此类动词有:insist, demand, suggest, propose, order, require, decide, ask, request, command等表示命令、建议、要求等.
例句: We all insist that we (should) not rest until we finish the work..
The professor suggests that the students (should) collect enough materials before they work on this project.
上面的动词如果以名词形式出现(如以表语从句,同位语从句形式出现)时,后面的that从句仍然要采用虚拟语气
例句:He gives me the suggestion that I (should) eat breakfast every morning.
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.
注意2:在一些惯用语之后经常需要用虚拟,来表示与事实相反或者难以实现的事情
这类习语有:as if , as though, but for, otherwise, without, wish, if only, for fear that, unless, in case, lest等
表示一种假设,就用虚拟语气
例句: But for your help, I would not have arrived here in time.
(如果没有你的帮助,我就不能准时到达)
Without your help, I would not arrive here in time.
She put a blanket over the baby for fear that he should catch cold. 她在那个婴儿身上盖上了毯子以免他着凉。
The bad man was put in the soft-padded cell lest he injure himself.
注意3:在下列形容词引导的that从句中必须要用虚拟语气(should) do,但是由于 should经常被省略,所以实际上用的就是动词原形。
这类形容词有: It is important/ necessary/ proper/ imperative(必要的)/ essential/ advisable等 + that
例句:It is necessary that he (should) realize his situation.
注意4:在虚拟语气的从句中,动词'be'的过去时态一律用"were",不用was,
即在从句中be用were代替。
例句: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. (如果他在这儿,一切都会好的。)
注意5:如suggest, insist不表示"建议" 或"坚持要某人做某事时",即它们用于其本意"暗示、表明"、"坚持认为"时,宾语从句用陈述语气。
例句:The guard at gate insisted that everybody obey the rules
