2018年专四真题虚拟语气和情态动词-章振邦语法书页数标注DC. would beD. were[译文]如果你把情况向你的事务律师说明，他会比我更能给你提出好的建议。

[考点]虚拟语气。

本句条件从句中的谓语动词用了过去式explained，但这是复合时态形式，主句说明其内容与现在/将来的情况相反，所以主句谓语应该由would+动词原形构成。

B，C不用于虚拟语气；D．were只用于表虚拟的条件句中。

9．___ if I had arrived yesterday without letting you know beforehand? （2004年44题）A. Would you be surprisedB. Were you surprisedC. Had you been surprisedD. Would you have been surprised44．答案：A 参考译文：如果昨天没有提前通知你，我就来了，你会觉得奇怪吗？试题分析：本题考查的是虚拟语气的用法。

详细解答：这是一个错综时间条件句。

条件从句表示的动作和主句表示的动作，发生的时间是不一致的，动词的形式要根据表示的时间来调整。

10．All of us would have enjoyed the party much more if there ___ quite such a crowd of people there. （2000年49题）A. weren’tB. hasn’t beenC. hadn’t beenD. wouldn’t be[解析]考点：虚拟语气。

由于主句中使用了would have done，即表示与过去事实相反，那么从句中相应地使用had done。

[译文]若不是那儿人太多，我们在聚会上都会玩得更尽兴的。

专四虚拟语气总结(打印)

专四语法（虚拟语气）虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。

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。

eg. If he comes, he will bring his violin.典型例题The volleyball match will be put off if it ___.A.will rainB. rainsC. rainedD. 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，主句谓语动词便不用shall (will) +动词原形，而直接用一般现在时的动词形式。

从句中提出一种与客观现实不相符或根本不可能存在的条件，主句会产生的一种不可能获得的结果。

条件句中的虚拟语气根据不同的时间有三种不同的形⏹If I had time, I would do it again.⏹If I had known of your arrival, I should have met you at the station.⏹If she had further considered the problem, she might have come to the correctconclusion.真题举例：1. All of us would have enjoyed the party much more if there _____ quite such a crowd people there.（00, 49）[C]A. weren’tB. hasn’t beenC. hadn’t beenD. w ouldn’t be2.

If there were no subjunctive mood, English _____ much easier to learn.(09, 52) [B]A. could have beenB. would beC. will beD. would have been4. _____ for the fact that she broke her leg, she might have passed the exam.(02, 60）[A]A.

I had not been called awayD. nobody called me away当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为：错综时间条件句，动词的形式要根据它所表示的时间做出相应的调整。

Would have done过去常常做某事；是对过去发生的事情的推断。

【分析】句意为“我原来能够早点来，但我真不知道他们在等我。

”but I didn’t know表示了过去时间，所以前句是对过去的虚构，用主语+should / would / could / might + have done表达，应选D。

专业四级考试语法-虚拟语气(全)

Subjunctive Mood1. 语气Mood语气是动词的一种形式，表示说话人对一事物和人的态度和看法。

包括陈述语气，祈使语气和虚拟语气三种。

陈述语气表示动作或状态是现实的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句。

①There are two sides to every question.每个问题都有两个方面。

②Were you busy all day yesterday?昨天一整天你都很忙吗？③How good a teacher she is!她是多好的一位老师啊！祈使语气祈使语气：表示说话人对对方的请求或命令。

① Never be late again!再也不要迟到了。

② Don’t forget to turn off the light.别忘了关灯。

虚拟语气表示动作或状态不是客观存在的事实，而是说话人的主观愿望、假设或推测等。

①If I were a bird, I could fly in the air.如果我是一只小鸟，我就能在空中飞行。

②I wish I could pass the examination.我希望我能通过考试。

③May you succeed!祝您成功！虚拟语气是动词的一种特殊形式，用来表达未能成为事实或者不可能成为事实的情况，或者在说话人看来实现可能性很小的情况。

此外还可用来表示命令、建议、设想、祝愿（或could have done 本来可以- - -might have done 本来可能- - -should / ought to have done 本来应该做- - -shouldn’t / ought not to have done 本不该做- -你本不应该告诉她真相。

You shouldn’t have told her the truth .needn’t have done 本不必做- - -比较：didn’t need to do 没必要做也没有做- - -我没必要擦窗户。

专题06 情态动词和虚拟语气2018年高考题1.2018·江苏24. It’s strange that he _______have taken the books without the owner’s permission.A. wouldB. shouldC. couldD. might答案B点睛：本题考查虚拟语气。

It is important/necessary/strange/impossible/natural that... 主语从句多数情况下用虚拟语气，表达一种要求、命令或者责备、建议或主观看法。

但是如果只是表示陈述一个事实而不是强烈的感情，完全可以用一般的陈述语气。

试比较： It is strange that he had made a mistake.（陈述一个事实：他犯了错误让人有点奇怪。

） It is strange that he (should) have made a mistake. （虚拟语气，说话者是在责备他本不应该犯错。

）2.2018·江苏27. There is a good social life in the village, and I wish I _______ a second chance to bee more involved.A. hadB. will haveC. would have hadD. have had答案A解析考查虚拟语气。

句意：在这个村里有很好的社交生活，并且我希望我再有机会去更多的参与。

本题考查wish引导的宾语从句，表示与现在事实相反的愿望，所以从句用一般过去时。

故选A。

点睛：本题考查wish引导的虚拟语气。

由wish引起的表示愿望的虚拟语气：1．用wish表示对现在的愿望时，它所引起的宾语从句中谓语动词形式为：过去式（be动词用were）。

2．用wish表示对将来的愿望时，它所引起的宾语从句中谓语动词形式为：would, could, might 动词原形。

PART III LANGUAGE USAGEThere are twenty sentences in this section. Beneath each sentence there are four options marked A B C and D. Choose the one that best completes the sentence or answers the question. Mark hour answers on ANSWER SHEET TWO.11. The Bent Pyramid outsi de Cairo __________ ancient Egypt’s first attempt to build a smooth-sided pyramid.A. has been believed to have beenB. was believed to beC. is believed to have beenD. is believed to beTo have done【解析】本题考查非谓语动词中不定式的用法，属于专四语法高频考点，考点拓展：不定式的完成时to have done表示三种意思，第一，跟在表示情感类的词后，比如sorry happy blessed。

第二，跟在表示观点的谓语动词，比如is said/ thought/believed to have done 第三，跟在表示推断类的谓语动词之后seem/appear等。

本题意思：据说开罗外的金字塔是古代埃及人的一次尝试，尝试建立一个smooth-sided金字塔。

is believed to have been 为什么是is believed 这里表示现在人们也是这么认为，所以is believed 用的是现在时态，to have been 表示“尝试”这个动作发生的时态在被认为之前，当然是古老的埃及人们做了这个尝试之后，才有后来的人们的“据说”。

这并不是因为他们完全不能体会快乐，也不是因为不能听音乐。

而是他们对音乐不敏感。

They can discriminate all the sounds of all languages,no matter what country we’re testing and what language we’re using,and that’s remarkable because you know,I can’t do that.We’re culture-bound listeners.We can discriminate the sounds of our own language,but not those of foreign languages.So the question arises:When do those citizens of the world turn into the language-bound listeners that we are?And the answer:before their first birthdays.What you see here is performance on that head-turn task for babies tested in Tokyo and the United States,here in Seattle,as they listened to the“ra”and“la”—sounds important to English,but not to Japanese.So at six to eight months,the babies are totally equivalent.Two months later,something,something incredible occurs.The babies in the United States are getting a lot better while babies in Japan are getting a lot worse.So the question is:What’s happening during this critical two-month period?We know this is the critical period for sound development,but what’s going on up there?Maybe there are two things going on.The first is that the babies are listening intently to us,and they’re taking statistics as they listen to us talk—they’re taking statistics.That is to say,the two babies listen to their own mother speaking motherese—the universal language we use when we talk to kids.During the production of speech,when babies listen,what they’re doing is taking statistics,that is,sound distribution on the language that they hear.And those sound distributions grow and babies absorb more.And what we’ve learned is that babies are sensitive to the statistics,and the statistics of Japanese and English are very,very different.I mean,the sound distribution of both languages is different.So babies absorb the statistics of the language and it changes their brains;it changes them from the citizens of the world to the culture-bound listeners that we are because we as adults are no longer absorbing those statistics.In this case,of course,we’re arguing that the learning of language material may slow down when our distribution stabilizes.OK.Today,we just talked about a recent project on babies’language development.In our next lecture,we will concentrate on bilingual people,how bilinguals keep two sets of statistics in mind at once.听力翻译婴儿的语言天赋大家早上好。

2018版英语大一轮复习语法考点讲练能力快速提升(北师大版教师用书)第五节情态动词和虚拟语气含答案

第五节情态动词和虚拟语气考法1考查情态动词的基本用法本含义.个别高频情态动词在特殊语境下的特殊含义（如:must“非得;偏要"，should“竟然”，shall用于第二、三人称表示警告、命令、威胁、允诺、规定等）是高考的热点和难点。

常见情态动词的基本用法是高考考查的重点。

(1）表示推测（可能性)对于情态动词表示推测的考查多以填空的形式出现，其特点有三：一是空格后紧跟动词原形;二是结合具体的语境命题；三是侧重must，can，could，may，might，should表示推测时在语气和句式上的差异.（2015·高考重庆卷改编)You be Carol.You haven't changed a bit after all these years.解析：句意：你一定是卡罗尔。

这么多年后你一点儿都没变。

根据语境可知，此处应该用情态动词表示推测,由下文“这么多年后你一点儿都没变”可推知此处为非常肯定的猜测.故填must，意为“一定”。

考法总结:空后为动词原形，故此处只能填助动词或情态动词；根据下文内容可知此处是说话人的猜测，因为有“据”可循，所以非常肯定，故填语气最为强烈的情态动词must，意为“一定”.（2）表示必要性、义务、责任等主要集中在考查must（意为“必须”），should和need等的用法上.（2016·高考北京卷改编）I love the weekend,because Iget up early on Saturdays and Sundays。

解析：句意：我喜欢周末，因为在周六、日我不必早起.根据句意可知填needn’t，意为“不必”.考法总结：根据考题要求,无提示词填空题只填1个词，所以此处不能填don’t have to。

（3）表示请求、建议、命令、允许、允诺、禁止等(2015·高考四川卷改编）You be careful with the camera.It costs！解析：句意：你必须要小心使用相机。
