虚拟语气解析以及练习题答案详细解答
虚拟语气解析及练习与答案详解虚拟语气一、虚拟语气的运用练习题及答案解释The millions of calculations involved, had they been done by hand,______all practical value by the time they were finished.A.could loseB. would have lostC. might loseD. ought to have lost解析：这个句子中含有一个省略if，把助动词提前到主语they之前的虚拟条件句，该条件句表示对过去情况的假设，而主句中by the time they were finished表明主句也应该是对过去发生的情况的假设，因而应该选（B）would have lost为正确答案。
2. Had Paul received six more votes in the last election, he our chairman now.A. must have beenB. would have beenC. wereD. would be解析：这道题目是一个混合虚拟语气的句子。
条件句省略了if，把助词had提前到主语前面，表示对过去情况的假设，而主句中now表明了对现在情况的假设，所以应选would(should, could, might)+动词原形这种表达形式。
四个选项中只有（D）是正确表达形式，故为正确答案。
3. If you Jerry Brown until recently, you’d think the photograph on the right was strange.A. shouldn’t contactB. didn’t contactC. weren’t to contactD. hadn’t contacted解析：until recently，因此（D）是正确答案，而主句是隐含的对现在情况的假设，该句是一个混合虚拟条件句。

一类是虚拟条件句。
一类是虚拟条件句。
如果假设的情况是如果假设的情况是有可能发生的，就是真实条件何。
在这种真实条件句中的谓语用陈述语气。
如: If it doesn’t rain tomorrow, we will go to the park.如果假设的情况是过去或现在都不存在的，如果假设的情况是过去或现在都不存在的，或将来不大可能发生的，或将来不大可能发生的，则是虚拟条件句。

英语虚拟语气答题技巧及练习题(含答案)及解析
英语虚拟语气答题技巧及练习题(含答案)及解析一、初中英语虚拟语气1．---If I were you, I ________ study harderA．had B．would C．did D . do【答案】B【解析】试题分析：虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。
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。
1、与现在事实相反若与现在事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用“should （would, could, might）+动词原形”2、与过去事实相反若与过去事实相反，条件从句的谓语用过去完成时（had+过去分词），主句谓语用“should （would, could, might）+have+过去分词”3、与将来事实相反若与将来事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用“should （would, could, might）+动词原形”：句意：如果我是你，我会学习更努力。
结合语境可知本句表示的是对现在的虚拟，故从句中用过去时态，主句中用过去将来时态。
选B。
考点：考查虚拟语气2．If I you, I the army.A．am, would join B．were, would join C．am, will join D．were, will join【答案】B【解析】试题分析：句意:如果我是你,我会参军.结合语境可知本句是对客观状况的虚拟,故用过去时态,主句用过去将来时态.选B.考点：if引导的条件状语从句点评：虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。
英语语法专项：虚拟语气用法详解及练习(附答案)
高中英语虚拟语气讲解及练习虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。
根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句（1）表示与现在事实相反If I had enough money now, I would lend it to you.（2）表示与过去事实相反If he had taken your advice, he wouldn’t have made such a bad mistake.（3）表示与将来事实相反I would go shopping with you if it were to be Sunday tomorrow.1. 虚拟条件句的倒装在虚拟条件句中，为了强调所假设条件的虚拟性，或突出说话人的一种主观愿望，虚拟条件句可用倒装结构。
虚拟条件句的倒装是通过去掉if，把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。
例如：Had I been（= If I had been ） in that situation， I would not have let the thief escape away with so much money.Should there be （= If there should be） a drought， what should we do at that time ？2. 错综时间条件句有时条件从句的动作和主句的动作发生的时间并不一致，这时谓语动词的形式应根据它所要表示的具体时间来确定。
例如：If we hadn’t been working hard in the past few years ，thing s wouldn’t be going so smoothly.3. 含蓄条件句有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。
虚拟语气总结附练习及答案
虚拟语气简介虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。
虚拟语气通过谓语动词的特殊形式来表示。
英语中的语气分为陈述语气、祈使语气、虚拟语气三类。
在表示虚假的、与事实相反的或难以实现的情况时用虚拟语气，表示主观愿望或某种强烈情感时，也用虚拟语气。
即当一个人说话时欲强调其所说的话是基于自己的主观想法，愿望，假想，猜测，怀疑或建议，而不是根据客观实际，就用虚拟语气。
①错综时间条件句: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表示的时间作出相应的调整。
如：If you had followed my advice just now, you would be better now.If you had studied hard before, you would be a college student now.②if省略句在条件句中可以省略if, 把were, had, should提到句首，变成倒装句式。
如：If I were at school again, I would study harder.→Were I at school again, I would study harder.如果我还有上学的机会，我会更加努力学习。
If you had come earlier, you would catch the bus.→Had you come earlier, you would catch the bus.如果你来得早点，你就能赶上公共汽车。
If it should rain tomorrow, we would not go climbing.→Should it rain tomorrow, we would not go climbing.如果明天下雨的话，我们就不能登山去了。

常用来表示含蓄虚拟条件的方式有：（1）介词或介词短语（代替状语从句）：but for（要不是…），without（假若没有…），with（假若有…）With your help, I could have finished the work ahead of time. 如果有你的帮助的话，我本可以提前完成这项工作。
Without air and water, there would be no living things on the earth. 如果没有空气和水，地球上就不会存在生物。
But for the rain, we should have had a pleasant journey. 如果不是因为下雨，旅途会很愉快。
（2）用or，otherwise(否则)，but等类似转折词We didn’t know his telephone number; otherwise we would have telephoned him.I would have come to help you ,but I was busy that day.I was ill that day. Otherwise, I would have taken part in the sports meeting.（3）根据上下文语境来表示某种假设情况Five minutes earlier and you could have met her at the station. 早来五分钟的话，你就能在车站见到他了。
