考情分析
分析近年高考真题可知,高考虚拟语气的考查可能出现在阅读的长难句中。语法填空中不作为考查热点,但在写作中能够成功地在应用文写作和读后续写中用上1-2句虚拟语气可以起到美化文章的作用。复习目标:1. 掌握if引导虚拟语气条件句的基本用法。2. 熟练运用虚拟语气的倒装和省略。3. 掌握三大从句中虚拟语气的常用法,如should+动词原形。4. 掌握虚拟语气的特殊句式。如It’ high time that...5. 熟练运用含蓄虚拟语气与错综虚拟语气句。掌握在复杂语境中辨别虚拟语气并正确理解句意的能力。

如果他还在这里,他就会帮助我们的。
例2.If I had been free,I would have visited you.(过去)
如果我有空,我会去看你的。
例3.If it should rain tomorrow, we would not go camping.(将来)
如果明天要下雨,我们就不去露营了。
思维建模:虚拟语气在长难句中可以通过辨析谓语动词的特殊形式来迅速甄别虚拟还是真实。
知识点1 if引导的虚拟语气典型用法
典例 1.(2025高三·全国·专题练习)If I had a chance to study abroad, I ________ (study) at Cambridge University.
【解析】考查虚拟语气。句意:如果我有机会出国留学,我会在剑桥大学学习。if的虚拟条件句使用了过去式,表示与现在事实相反,主句用would do。故填would study。
【答案】would study

典例2.(23-24高三·黑龙江哈尔滨·期中)If motorists _________ (avoid) speeding on highways, there would not be more traffic accidents reported.
【解析】考查虚拟语气。句意:如果驾驶者在高速公路上避免超速行驶,就不会有更多的被报道的交通事故了。分析句子可知,此处为if引导虚拟语气句型中从句谓语动词的填入,结合句意以及主句动词would not be可知,此处应为对现在情况的假设,所以从句动词为一般过去时。故填avoided。
【答案】avoided

在条件句中,如果有were, had, should等,则可省略if,但应注意把were, had, should等提到从句主语之前。
例1.If he were to come, I would join him in the discussion.(对将来虚拟)
=Were he to come, I would join him in the discussion.如果他来,我将和他一道参加讨论。
例2.If you had turned to me, I would have helped you. (对过去虚拟)
= Had you turned to me, I would have helped you.如果你请我帮忙,我就帮你了.
例3. If I weren't busy, I would have come.(错综虚拟)
=Were I not busy, I would have come.
例4.Had you come a few minutes earlier,you would have seen him.如果你早来几分钟,你就能看见他了。
名师提醒:在虚拟条件状语从句中,省略连词的倒装形式的句首不能用动词的缩略形式.比如我们可说Were I not busy,而不能说 Weren't I busy.
知识点2 虚拟语气的省略和倒装
典例1.(2024高三·全国·专题练习)__________he leave today, he would get there by Friday.
【解析】考查虚拟语气和倒装。句意:如果他今天出发,星期五就能到那里。结合句意和主句谓语动词would get可知,此处为if引导的虚拟条件状语从句,与将来的事实相反,从句谓语动词可用did/were to do/should do;根据动词原形leave可知,此处为should do;当从句有should时,可省略if,并将should置于主语之前。综上,故填Should。
【答案】Should

变式训练. __________ we made a great effort last term, we might have succeeded.
【解析】考查虚拟语气。句意:如果我们上学期努力了,我们可能会成功的。分析句子结构和主句的might have succeeded可知,此处考查if引导的虚拟语气。再根据we made a great effort last term可知,这是表示对于过去是事情的假设,从句应用过去完成时,此处省略if将助动词had置于句首,构成部分倒装。故填Had。
【答案】Had

当条件从句的行为与主句所表示的行为所发生的时间不一致时,主从句中动词的形式要根据它所表示的时间作出相应的调整,我们称之为错综条件虚拟语气。
例1.If they had studied hard, they could do it easily now.(从句过去,主句现在)
如果他们以前努力学习的话,现在做得就会容易些了。
例2.If he had not taken my advice, he wouldn't do it much better like this.(从句过去,主句现在)
如果他过去不听我的建议,他就不会做得这么好了。
例3.If you had asked him yesterday, you would know what to do now. (You didn't ask him yesterday, so you don't know what to do now.(从句与过去事实相反,主句与现在事实相反)
如果你昨天问了他,现在你就知道要做什么了.
知识点3 错综虚拟语气
典例(24-25高三·全国·专题练习)If he had spent more time practising speaking English before, he________ (be) able to speak it much better now.
【解析】考查虚拟语气。句意:如果他以前花更多的时间练习说英语,他现在就能说得更好了。本句是虚拟语气含蓄条件句,now说明主句与现在事实相反,应用would do。故答案是would be。
【答案】would be

含蓄条件句是指非真实条件句中的条件从句有时是暗含在上下文中的.含蓄条件句常见的表达方式有:
1.介词及介词短语 but that, but for, without, with, under, under ... condition, supposing, on condition that, in the past 等.
例1.But for air and water, there would be no life on the earth. (but for提供了虚拟条件)
要是没有空气和水,地球上就没有生命。

3.根据上下文推理出条件.
例1.It would do you no good.这可能会对你没好处.
(条件可能是if you should give up the job“如果你放弃这项工作的话

知识点4 含蓄虚拟语气
典例1.(24-25高三·全国·专题练习)But for the medical team’s efforts, more lives (claim) in this pandemic.
【解析】考查含蓄虚拟语气。句意:要不是医疗队的努力,这场大流行病会夺去更多的生命。这是一个含蓄虚拟语气,表示与过去事实相反的假设,主句:主语 + should(would, could, might)+have done+其他。claim 意思是夺去,“生命”和“夺去”之间是被动关系,用被动语态,所以填would have been claimed。
【答案】would have been claimed

7.(24-24高三·全国·专项训练)It's high time that we __________(apply )ourselves to the task of protecting our environment.
【答案】applied/should apply
【解析】考查虚拟语气。句意:该是我们投身于保护环境这项任务的时候了。在“It's high time+that从句”这一句型中,从句谓语动词常用一般过去时或“should+动词原形”,其中should不能省略,故填applied/should apply。
