高中英语语法情态动词与虚拟语气讲解
高中英语语法情态动词与虚拟语气讲解情态动词的基本用法情态动词具有一定的词义，没有人称和数的变化，必须和其他动词一起构成谓语，用来表示愿望、态度或推测等。
1．表示能力(2)表示将来的能力：will be able to(3)表示过去的能力I can't promise anything, but I'll do what I can.我不能许诺什么，但我会尽力而为。
(表示现在的能力)The fire spread through the hotel very quickly but everyone was able to get out.尽管这场大火迅速蔓延到了这个宾馆，但是每个人都逃了出去。
(表示过去有能力做并且成功地做了)I could have worked out the problem, but I was too nervous.我本来可以解出这道题，但我太紧张了。
(表示本来有能力做但未做)2．表示推测(可能性)可能性可分为客观的可能性和具体事情实际发生的可能性两种。
(1)客观的可能性并不表示具体某事是否会发生，而用来说明人或事物的特征。
情态动词can可用于肯定句中表示客观的(或理论的)可能性，而表示具体事情实际发生的可能性时， can 一般不用于肯定句。
Accidents can happen on such rainy days.在这样的多雨天气里可能会发生事故。
(表示客观的可能性)We may go to the cinema tonight, but we are not sure yet.今晚我们可能去看电影，但还没确定。
(表示实际可能性，不用can)(2)表示具体事情实际发生的可能性表示具体事情实际发生的可能性的层次(由强及弱)比较：①在肯定句中表示推测(must/have to, should/ought to, may, might, could)a．当说话者表达怀疑或犹豫之意时，需用may, might或could, 其中might, could比may所表达的怀疑或犹豫之意更强。

榜首部分、神态动词一、can/could与be able to1．can/could用来标明“一般才能”；be able to有多种时态，且用来标明在特定条件下的“详细才能”。
如：My grandma is over seventy，but she can stillread without glasses.They will be able to tell you the news soon.He was able to flee Europe before the war broke out.2．标明答应可用can或could，与may/might含义挨近。
could可用于现在时，仅仅口气愈加宛转、谦让，答复时则一般要用can而不用could。
—Could I have the television on?—Yes，you can./No，you can't.二、may与might1．标明答应，意为“能够，答应”，用法根本上同can与could。
如：May I use your bicycle?2．标明或许性，意为“或许，或许”。
如：According to the weather forecast, it may rain tomorrow.3．may能够放在句首，标明祝福。
如：May good luck be yours!三、must与have to1．must用来标明说话人的片面观点；have to标明客观的需求，着重外界压力，不得已而为之。
如：He said that they must work hard。
他说他们有必要努力工作。
(片面上要做这件事)My brother was ill, so I had to call the doctor in the middle of the night.我弟弟生病了，我只得半夜里把医师请来。
(客观上需求做这件事)2．标明“不用”，须用don't have to或needn't。

高考英语考点之情态动词和虚拟语气
高考考点之情态动词和虚拟语气考点详解【命题解读】英语中常用的情态动词主要有can，could，may，might，must，will，would，shall，should，ought to，dare，need，used to，had better等。
在学习情态动词时应注意以下几点：同一情态动词表示不同的意义的情况；情态动词后跟各种形式的用法；尤其要注意＂情态动词+完成式＂是高考中的重点所在。
对虚拟语气的考查重点在于根据句子的语境灵活多样地运用虚拟语气，宾语从句中虚拟语气的应用，交际用语中为表示委婉而使用的虚拟语气，含蓄条件句中的虚拟语气，以及特殊句型中的虚拟语气等。
【命题预测】情态动词是2021年各地高考试题中的必考项目，每年高考单独命题区的单项填空必有一道考查情态动词的项目。
新课标卷主要在语法填空和短文改错中考查。
考点依次是：推测(可能性)→请求/允许→必要性→特殊用法。
试题的立意不偏不怪，但有效信息越来越隐蔽，语境越来越真实，考查角度越来越细致，这些因素在很大程度上增加了试题的难度。
情态动词和虚拟语气与动词的时态和语态相结合的考查是近年来高考的趋势。
【复习建议】情态动词：1. 掌握情态动词的基本用法；2. 掌握情态动词表达＂情感、态度、语气等＂方面的用法。
虚拟语气：1. 掌握虚拟语气的基本用法；2. 掌握含蓄虚拟条件句的用法；3. 掌握主从句时间不一致的虚拟条件句的用法；情态动词考向一情态动词的基本用法1）can，could与be able to1．表示能力，意为＂能，会＂。

高考英语二轮复习知识点：情态动词和虚拟语气
高考英语二轮复习知识点：情态动词和虚拟语气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。

英语中常用的情态动词主要有can，could，may，might，must，will，would，shall，should，ought to，dare，need，used to，had better等。
在学习情态动词时应注意以下几点：同一情态动词表示不同的意义的情况；情态动词后跟各种形式的用法；特别是注意“情态动词+完成式”是高考中的重点所在。
can，could与be able to的用法1．表示现在的能力：can，am/is/are able to。
2．表示将来的能力：will be able to。
3．表示过去的能力：could表示过去的能力，不表示是否成功地做了；was/were able to表示过去有能力做而且成功地做了。
4．can/could表示惊讶，常用在否定句和疑问句中。
5．can/could表示礼貌地请求别人做某事，意为“能，可以”。
may与might的用法1．表示请求、允许时，might比may的语气更委婉一些，否定回答时要用mustn't，表示“不可以”“禁止”“阻止”之意。
2．may/might还可以表示推测，意为“可能”。
3．“may/might as well＋动词原形”意为“最好，倒不如”。
must的用法1．must用于否定句，表示“禁止”，表示说话者的命令或指令，语气比较强烈。
2．must表示必要性，意为“必须”。
