高考英语复习知识点：情态动词和虚拟语气及英语作文结尾万能公式高考英语复习知识点：情态动词和虚拟语气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.couldntB.shouldntC.cantD.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。

因为是发生在过去的事实，所以正确答案为A。

3.与将来事实相反的虚拟语气，基本结构为：主语+动词的一般过去时/should do/were to do+其他成分+if+should/would/could...+动词原形+其他成分。

2019届高考英语总复习--助动词、情态动词和虚拟语气（共2套含答案）第七讲助动词、情态动词和虚拟语气助动词顺口溜巧记助动词Ⅰ 示之以范____________________________________________________原则这样运用 1．(2017•贵州适应性测试)What about Japanese? They dislike the lotus and ____________ not give it as a gift to Japanese because they regard it as the mourning flower. do 解析：考查时态和主谓一致。

结合语境可知，该句陈述的是一般常识，应用一般现在时，且主语为they，故该空用助动词do。

2．(2017•浙江卷)Without hesitation, I decided to follow them and we did had lots of fun that day.____________________ had→have解析：did加强语气，后跟动词原形。

3．She doesn’t her homework in the morning but in the evening.____________________ doesn’t后加do 解析：doesn’t为一般现在时的否定式后加动词原形。

4．This experience has been shown that traveling by train actually is the safest way of makingjourneys.____________________ 去掉been 解析：show和this experience为主动关系，故去掉助动词been。

5．My father has always go to work by bike since then.____________________ go→gone解析：由since then可知该句应用完成时，go的过去分词为gone。

高考专题虚拟语气I、重点难点解析虚拟语气的高考命题导向：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。

真实语气与虚拟语气的区别主要在谓语动词的形式上。

在做题时，要根据语境判断出是与那种时态相反的虚拟语气。

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，只能用were。

2. suggest表“暗示、表明”和insist表示“坚持认为”,其后的宾语从句用陈述句语气。

例如：You pale face suggests that you are ill. / He insisted that he was right.3. if虚拟语气条件句中如有had, should, were，可省略if, 将其提前引起倒装。

例如：Were I you, I would remain. / Had you told me earlier, I wouldn’t have missed it.4. 可用without, but for(“要不是”)代替虚拟语气条件句。

例如：But for your help, I would have failed the exam.Without air there would be no life.5.as if/though, even if/though也可以不用虚拟，表示真实的情况。

例如：It looks as if it is going to rain.II、实战演练用所给动词的适当形式填空1.---If he ________________ (warn), he ________________ (not take) that food.---Luckily he was sent to the hospital immediately.2.When a pencil is partly in a glass of water, it looks as if it _________________ (break).3.I would rather they _________________ (not hear) of the news.4.I wish I _______________ (have) a room of my own when I was a child.5.To the surprise of the public, the identification of the cause of such a simple event ___________________ (take)more than a year.6.Without air to hold some of the sun’s heat, the earth at night _______________ (be) freezing cold, too cold for us tostay.7.If I had worked harder at school, I _____________________(sit) in a comfortable office now.8.Her pale face suggested that she _____________ (be) ill, and her colleagues suggested that she _____________(have) a medical examination.9.I insisted he ____________ (go) to see a doctor, but he insisted nothing __________ (be) wrong with him.10.He asks that he _______________ (give) an opportunity to explain why he’s refused to go there.11.It is high time we _____________ (get) down to discussing this plan.12.If it were not for the fact that you ___________ (be) too busy, I would ask you to help me do this right now.
