求教!虚拟语气。

"If I should be given a chance, you wouldn't ..." 虚拟语气,表示对将来的虚拟,“如果将来你给我一个机会,你绝不会..“

请问前半句可以省略吗?能的话该怎么省略呢?

是一个比较困难的语法问题。然而只要我们好好总结一下虚拟语气的构成和用法,那就可以化难为易了。现将虚拟语气有关用法归纳如下:

1.虚拟语气在条件句中的用法
        (1)若表示与现在事实相反的假设,则条件从句中用过去式,主句中用过去将来式(would,should,could,might + 动词原形);若表示某事将来实现的可能性不大,则条件从句中用should + 动词原形也可用“were to+动词原形”或用过去式动词。如:
            I would certainly go if I had time.(现在)
            If it should rain,we wouldn”t go out.(将来)
            If I knew German,I would read the paper to you.(现在)
            If he were here,we could ask him.(现在)
        (2)若表示与过去事实相反的假设,从句中用过去完成式,主句中用过去将来完成式(should,would,could,might + have + 过去分词)。如:
            If I had set off a little earlier, I would have caught the train.
            She would / might have come if she hadn”t been so busy.
            If I hadn”t taken your advice,I would have made a bad mistake.
            If only you hadn”t told him the news.
        (3)含有虚拟语气的条件状语从句中,如有had,should,were 这三个词的话,在正式或书面语言中可将if省略,再将句子的主语和谓语动词实行全部倒装或部分倒装。如:
            Had they time(=If they had time),they would certainly come and help us.
            Should it be fine(=If it should be fine),we would go for an outing.
            Were I go(=If I were you), I would go.
        (4)若主句从句所指的时间不一致,即条件从句表示与过去事实相反,主句表示与现在事实相反;或者条件从句表示与现在事实相反,主句表真实情况,则从句中应采用与具体时间相对应的虚拟形式。如:
            If it had rained last night(过去),It would be very cold today(现在).
            If I had taken your advice(过去),I should have no trouble with the work now(现在).

2.虚拟语气在宾语从句中的用法
        在动词suggest,order,demand,propose,request,command,insist等后的宾语从句中,用虚拟语气(即Should+动词原形或只用动词原形)来表示愿望、建议、命令、请求等。在动词wish /would rather后的宾语从句中,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。如:
            I suggest that we(should)set off at once.
            The doctor insisted that the patient (should)be X-rayed.
            I wish I were as strong as you.
            I would rather that you hadn”t told him.

3.虚拟语气在主语从句中的用法
        在It is necessary/important/strange/natural;It is requested/suggested/desired/proposed;it is a pity等结构后的主语从句中要用虚拟语气,即Should+动词原形或只用动词原形。如:
            It is necessary that he(should)be sent there at once.
            It is requested that Professor Li(should)give us a speech.
            It is desired that we(should)get everything ready by tonight.

4.虚拟语气在表语从句、同位语从句中的用法。
        在 suggestion, proposal,idea,plan,order,advice等名词后的表语从句、同位语从句中要用虚拟语气,即should+动词原形或只用动词原形。如:
            Our suggestion is that you( should)be the first to go.
            My advice is that we(should)send for Doctor Li.
            Do you know the order that you(should)keep watch?

5.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.
            He took a taxi to the station so that she should not miss the train.

6.虚拟语气在定语从句中的用法:
        在it is time后面的定语从句中常用过去式表示虚拟。

不可以省略的。因为主句和从句主语不同。
我想你是把它和另外一种情况混淆了。下面的这种情况是可以省略的:
If I should be given a chance, I would try my best.
前半句从句可以缩写为:
Given a chance, I would try my best.
记住哦,主语一致才可以本回答被提问者采纳

你好。前面的从句不能省略,只能倒装:
1 should I be given a chance, you wouldn't regret
2 Were I to be given a chance, you wouldn't regret.
3 Were you to give me a chance,you wouldn't regret.

还有,我不明白,为什麼要省略?

听老师之间的对话学习虚拟语气

求教,虚拟语气的公式及用法。
一、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。二、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...

求教!虚拟语气。
在动词suggest,order,demand,propose,request,command,insist等后的宾语从句中,用虚拟语气(即Should+动词原形或只用动词原形)来表示愿望、建议、命令、请求等。在动词wish \/would rather后的宾语从句中,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。如:I suggest that we(should...

but for虚拟语气问题!求教!
could have done 和should have done 都是虚拟语气,只是情态动词could 和should 的含义不同,could 表示本可能,should 表示本应该, 表示有责任和义务到,语气不对。

英语单项求教!!!
这是虚拟语气,两个分句都与过去事实相反,要用完成时。If I had taken his advice, I wouldn't have made such a silly mistake.省去if时,要倒装:Had I taken his advice, I wouldn't have made such a silly mistake.至于为什么要用would 而不用should,从意思上讲,第一件事可以说自己...

大神求教!
句意:我们不知道他的电话号码,否则我们就会给他打电话。这里otherwise相当于一个虚拟条件句:If I had known his telephone number,主句应该使用和过去相反的虚拟语气,所以用would have done,选C。考点: 考查虚拟语气 【答案】C

求教英语语法选择 ___ the expense, I ___ to Italy.
D选项的语法有错,应该是if it hadn't been for.这道题考的是虚拟语气的时态问题,意思是如果不是因为经费问题,我会去意大利,是对现在的情况的假设。如果最后一个选项语法没错那就是“如果不是因为经费问题,我早就去了意大利是对过去的假设,也是没有问题的。

英语必采纳,不懂,求教
选D没错的。要用过去完成时表示虚拟语态。你要弄清楚他这句话的意思:要不是昨天我们在那个小村子里迷路了,我们昨天就会到更多有趣的地方玩了。

...的是什么三建议···之类的,高一教的忘了!求教!具体点
某个事实”则不用虚拟语气。 eg: He insists he is a student. 他坚持说他是个学生。 这个语句表示的是事实,因此在这个语句中不能使用虚拟语气。 suggest意为“建议”才用虚拟语气,意为“暗示”则不用虚拟语气。 eg: His face suggests that he looks worried . 他的表情暗含着他很担心。

求教几组词用法区别
六、 “might+have+done”表示对过去事情的推测,might与may意思相同,但可能性更小。多用于虚拟语气结构中。1. He might have given you more help, even though he was busy. 他或许会多给你一些帮助,即使他很忙。2. She might have achieved greater progress, if you had given her more ...

虚拟语气中什么时候一定要用were
答案是:在表示与现在相反的事实时,如果用到be动词,不管主语是单复数还是第几人称一律使用 be动词were ~手工翻译,尊重劳动,欢迎提问,感谢采纳!~
