我的虚拟语气
虚拟语气
一、概念
[Subjunctive Mood]
中文译作"虚拟语气"。它是一种动词形式,表示说话人的某种假设、愿望、怀疑、猜测、建议等含义。
二、语法结构
1.if结构(非真实条件句——表示的是假设的或实际可能性不大的情况)
与..事实相反 If从句 主句
过去 Had done Would* have done
现在 Were/did Would* do
将来 Should do/were/were to do Would* do
例句:If there hadn’t been much rain in spring, we would have had a good harvest now. [过去]
If he smoked less, his cough might be well soon. [现在]
If the lecturer should be late, you would have to make a speech first. [将来]
备注:
(1)上表中’*’,would都可转换为should、could、might。
(2) 如果为时间错综句的话,左右两栏可互相搭配,排列组合。
例句:
He would still be alive today if he hadn’t taken that drug.
[与现在事实相反] [与过去事实相反]
(3) if可转换为其他形式
例句:Without your advice, our meeting wouldn’t have been so successfully. [过去]
(=>可转换为:If there hadn’t been your advice, we …)
Your notes are almost illegible (难以辨认的). Notes typed out would be a lot easier to read. [将来]
(=> 可转换为:If the notes had been typed out, it would be a lot easier to read.)
I should have gone to see Dr. Smith and he might have cured me of the disease.[过去]
(=> 可转换为:If he have gone to see Dr. Smith, he ..)
2、wish结构
与..事实相反
过去 Had done
现在 Were/did
将来 Would
备注:可转换为其他形式。
例句:He talks as if (好像) he had done all the work himself. [过去]
I wish I were a bird.
I wish he handn' done that.
I wish I would be rich in the future.
3、should结构
从句中用“should + 动词原形”构成。而且should可以省去。用于此结构的动词有:advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose, request, suggest,intend等。
例句:The teacher suggest he (should) read English aloud.
注意:当insist表示“坚持认为”、suggest表示“表明,显示”时,不用虚拟语气。
例句:The look on his face suggested that he was quite satisfied with what I had done for him.
He insisted that he was honest.
4、would rather +从句
在这种结构中,从句的谓语动词用过去形式表示虚拟。
例句:I would rather you did this instead of me.
5、主语从句中的虚拟语气
1)It be + 形容词 + that ...(should)...
用于该句型的形容词是:necessary, good, important, right, wrong, better, natural, proper, funny,
strange, surprising .
一些名词也可以用于 在该结构中。如:a pity, no wonder....
2)It be + 过去分词 + that ...(should)....
用于该结构中的过去分词是表示“建议、请求、命令”等词的过去分词。如:desired, suggested, requested,
ordered, proposed等。
3)It is time(about time, high time)that ...(过去式动词形式或should+动词原形)....
It is high time I went home now. = It is high time I should go home now.
6、表语从句、同位语从句中的虚拟语气
在suggestion, proposal, order, plan, idea, advice, decision等需要有内涵的名词后面的表语从句、同
位语从句中,要使用虚拟语气。其谓语动词应用:should+原形动词。另外连接从句的that不能省
略。
例:My suggestion is that we should go there at once.
What do you think of his proposal that we should put on a play at the English evening?
三、使用范围及判断
1、虚拟语气表示一种不能实现的假设。该语法主要用于if条件状语从句。也可用于主语从句、表语从句、宾语从句等。
2、if条件状语从句中虚拟语气的判断
判断是真实条件句还是非真实条件句。只有在非真实条件句中才使用虚拟语气。通过句子意思,看假设的条件是否能够实现,能够实现是真实条件句,不能使用虚拟语气;假设的条件不能实现则是非真实条件句,要用虚拟语气。
判断这个假设是与哪个事实相反。通常有三种情况:①与过去事实相反。②与现在事实相反。③与将来事实可能相反。
3、“后退一步法”
后退一步法是指在准确地判断了该句与哪一事实相反后,按虚拟语气的后退一步法处理从句谓语动词的时态。即:在非 真实条件状语从句中,谓语动词按正常情况“后退一步”。也就是:
1)与过去事实相反,在从句中用过去完成时形式表示。
2)与现在事实相反,在从句中用过去一般时形式表示。
3)与将来事实可能相反,在从句中用过去将来时形式表示。
主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。
例:If I had come her yesterday, I would have seen him.
If I were a teacher, I would be strict with my students.
If it should snow tomorrow, they couldn’t go out.
四、注意事项
1.if条件句中如有were, should, had,可以省去if,并使用倒装语序。
2、在现代英语中if条件状与从句中的谓语动词如果是be其过去形式一般用were。
3、wish 后面宾语从句中的虚拟语气,按“后退一步法”处理从句的谓语动词。注意:与哪个事实相反,不能以主句的时态为判断依据,而是根据从句的意义判断。
英语虚拟语气的用法归纳
概述 英语的动词有三种语气形式,即陈述语气、祈使语气和虚拟语气。陈述语气用来说明事实或就事实提出询问,可用于陈述句、疑问句和某些感叹句中;祈使语气用于表示请求、命令、建议或警告等。
虚拟语气是谓语动词的一种特殊形式,用来表达假设、主观愿望、猜测、建议、可能或空想等非真实情况。如:
He is honest. 他很诚实。 (陈述语气)
Don‘t be late next time. 下次别迟到。 (祈使语气)
If I were you ,I would not go. 我要是你,我就不会去。 (虚拟语气)
I wish I had a lot of money. 要是我有很多很多钱就好了。 (虚拟语气)
编辑本段第一类 虚拟语气在条件句中的用法:
条件句有真实条件句和虚拟条件句两种。真实条件句所表示的假设是有可能发生的,此时主句不用虚拟语气;而虚拟条件句则表示一种假想,与事实相反或不大可能会发生,此时用虚拟语气。如:
If I have time,I will go. 假若我有时间,我就去。 (陈述语气) If I were you,I would go. 假若我是你,我就去。 (虚拟语气 )
if虚拟语气的例句
与过去事实相反:If she had seen you yesterday,she would have asked you about it.要是她昨天看见你,她就要向你问起这件事。
与现在事实相反:If i knew his telephone number,i would ring him up.如果我知道他的电话号码,我就会打电话给他。
与将来事实相反:If it should rain tomorrow,the crops would be saved.
要是明天下雨的话,庄家就有救了。
