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)、对现在情况的虚拟(与现在的事实相反):从句用过去式或过去进行式(时间上是同时的)。

混合虚拟语气的用法归纳引言虚拟语气是英语语法中一个非常重要的概念,它表达的是一种假设、愿望或不可能实现的情况。
在使用虚拟语气时,我们可以运用不同的时态和情态动词来达到不同的表达效果。
其中,混合虚拟语气是一种特殊的方式,指代过去时间但对于结果产生影响的状况。
我们将在本文中详细探讨混合虚拟语气以及其常见用法。
一、介绍混合虚拟语气混合虚拟语气架构于过去时间,表示与现实相反和与当前事实无关的假设条件。
也就是说,在使用混合虚拟语气时,我们将主句置于过去完成时,从句中则采用过去式来描述所假设的情况。
此外,分辨成真和成假条件也是理解混合虚拟语气的关键。
二、表示对现在情况无法改变的后悔1. "If only" 句型"If only" 用于表达对过去某个事件感到遗憾或后悔,并且现在无能为力去改变它。
这种结构中,主句使用了过去完成时,从句中的动词采用了过去完成时或者强调情态动词。
例句:- If only I had studied harder for the exam, I would have passed it.(要是我当初更努力地学习考试,我就能通过了。
)- If only she had listened to my advice, she wouldn't be in this mess now.(如果她当初听我的建议,现在她就不会陷入这种困境。
)2. 表示对过去错误决定的后悔使用虚拟语气来表示对于以前做出的决定和选择感到遗憾和后悔常常是混合虚拟语气的典型应用之一。
例句:- I wish I hadn't quit my job without a backup plan.(我真希望当初没有毫无准备地辞掉工作。
)- We regretted that we hadn't bought the tickets earlier when they were still available.(当时门票还有余额时我们没有早点购买真是后悔不已。

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。
