2020年高考英语语法必考考点(8)虚拟语气及情态动词【考点解读】 情态动词是每年高考的热点也是难点,每年单项填空题必考一题。
考点集中在:情态动词表示推测的基本用法及区别;情态动词否定式的用法辨析:“情态动词+have done”的用法区别等。
虚拟语气在高考命题中不是重点,但是难点。
考点常集中在含蓄条件句以及主语、宾语从句等特定句型中虚拟语气的使用上,因此考生应熟练掌握含蓄条件句中主从句的时态要求以及一些典型句型中虚拟语气的具体形式。
虚拟语气考点透析 考点一、虚拟语气的基本用法 1.与现在事实相反的虚拟语气,基本结构为:主语+动词的一般过去时(be动词用were)+其他成分+if +should/would/could...+动词原形+其他成分。
例如: ①If it were not for the fact that she ______ sing,I would invite her to the party.A. couldn’tB. shouldn’tC. can’tD. might not 解析句意为:如果不是因为她不会唱歌的事实,我会邀请她来参加那次聚会的。
that从句为同位语从句,描述的是事实,用陈述语气。
正确答案为C。
2.与过去事实相反的虚拟语气,基本结构为:主语+动词的过去完成时+其他成分+if +should/would/could...+have done+其他成分。
例如: If the weather had been better,we could have had a picnic. But it ______ all day.A. rainedB. rainsC. has rainedD.is raining 解析句意为:如果天气好的话,我们是能够去野餐的,但是下了一天的雨。
句子前半部分陈述的是与过去事实相反的事情,所以用了虚拟语气。
“下了一天的雨”是事实,所以用陈述语气。

虚拟语气详讲及练习一、定义:虚拟语气表示动作或状态与事实相反,或不可能发生的情况。
1.虚拟语气用于条件状语从句中1)表示与现在事实相反或不可能发生:一般过去时(虚拟语气中be→were)Eg. If he had time, he would (could, might) go with youEg.If I were you, I would work hard.2)表示与过去事实相反或不可能发生Eg.If he had taken my advice,he would have succeeded in passing the examination.Eg.If they had helped us, we would have finished the task. (实际上没帮)3)表示与将来的事实可能相反或不可能发生Eg.If it should rain, the crops would be saved.Eg.If it were to snow tomorrow, they would not go out.4)※注意:虚拟语气的倒装语序:如果if从句里含有should, had, were或其他助动词,则可将从属连词if省去,将助动词.情态动词.be或have放在句首形成部分倒装.Eg.If he had finished the work yesterday, he would have gone to the concert with you.=Had he finished the work yesterday, he would have gone to the concert with you.Eg.If I were you, I would go to the party.=Were I you, I would go to the party.Eg.If it should rain tomorrow, I would stay at home=Should it rain tomorrow, I would stay at home.2. 虚拟语气在宾语从句中的用法➢在动词wish后的宾语从句中,表示与现在或过去的事实相反,或对将来的主观愿望,从句通常省略连词that。
语法专题虚拟语气[考点解析]1 虚拟语气用于条件状语从句中(1)表示与现在事实相反的假设,条件状语从句中的谓语动词用“过去式(be动词过去式用were)”,主句中的谓语动词用“would / should/ could / might + 动词原形”。
如:If she had time, she would(could, might)help me.如果她有时间,她就会帮我了。
(事实上她没有时间)(2)表示与过去的事实相反,条件状语从句中的谓语动词用过去完成时,主句中的谓语动词则用“would / should / might / could + have +过去分词”。
如:It we had started earlier, we should not have missed the train.如果我们早点出发, 就不会错过这列火车了。
(3)表示与将来事实相反,条件状语从句中的谓语动词用一般过去时或should(were to) + 动词原形,主句中的谓语动词则用would / should/could might + 动词原形。
如:If Professor Li should have/were to have/had time tomorrow, we could ask himquestions. 如果李教授明天有时间的话, 我们就可以问他问题了。
虚拟语气用于条件状语从句中时,主句和从句谓语动词的形式见下表:(1)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,动词的形式要根据它所表示的时间作相应调整。
如:If China had not been liberated, the working people would still be leading a miserablelife. 如果中国没有解放,那么劳动人民仍会过着悲惨的生活。
(从句指过去, 主句指现在)(2)在if引导的表示虚拟的条件状语从句中,常可以省略if,将had, were或should 提至句首。

虚拟语气重难点分析虚拟语气是英语中一个较大的语法项目,高考语法填空和短文改错都曾经设过考点,考生应予以重视。
英语中的语气分为陈述语气、祈使语气、虚拟语气、疑问语气和感叹语气五类。
虚拟语气表示说话人的愿望、假设、猜测或建议,而不是表示客观存在的事实。
此外如需表达主观愿望或某种强烈的感情时,也可用虚拟语气。
虚拟语气通过谓语动词的特殊形式来表示。
一、虚拟语气在从句中的用法和构成一览表二、其他要注意的事项1. 虚拟语气中出现be的过去式,在口语中,当主语是第一、三人称单数时,可用was,但在if的倒装句中只能用were。
如:Were I you, I would apologize to her. 如果我是你的话,我就会去向她道歉。
2. suggest表“暗示、表明”和insist表“坚持认为”时,其后的宾语从句用陈述语气。
如:Your pale face suggests that you are ill. 你苍白的脸色表明你生病了。
He insisted that he was right. 他坚持认为他是对的。
(如insist表“坚持要求”时,其后的宾语从句则要用虚拟语气)3. if虚拟语气条件句中如有had, should, were,可省略if,并将这些词提前引起倒装。
如:Were I you, I would remain. 如果我是你,我会留下来。
Had you told me earlier, I wouldn’t have missed it. 如果你早点告诉我,我就不会错过它了。
4. 可用without, but for构成的介词短语代替虚拟语气条件句。
如:But for your help, I would have failed the exam. 如果没有你的帮助,我不会通过考试的。
Without water, there would be no life. 没有水,就没有生命。
5. as if/though, even if/though引导的从句也可以不用虚拟语气,表示真实的情况。
如:It looks as if it is going to rain. 看起来似乎要下雨了。
