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。

高考英语情态动词和虚拟语气讲解
（一）虚拟语气常考点（一）虚拟语气在非真实条件句中的运用使用虚拟条件句时要注意的几点：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，被称为“错综时间条件句”，动词的形式要根据它所表示的时间做出相应的调整。
如：If you had studied hard before，you would be a college student now。
假如你以前学习努力的话，你现在将已是一名大学生了。
2.if省略句在条件句中可省略if，把were，had，should提到句首，变为倒装句式。
如：If I were at school again，I would study harder。
→Were I at school again，I would study harder。
假如我再次回到学校，我一定更加努力的学习。
If you had come earlier，you would catch the bus。
→Had you come earlier，you would catch the bus。
假如你来早点，你就赶上公交车了。
If it should rain tomorrow，we would not go climbing。
→Should it rain tomorrow，we would not go climbing。
假如明天下雨，我们就不去爬山了。
注意：当省略的条件句中的谓语动词是否定形式时，不能用动词的缩略形式。
比如，我们可以说：Were it not for the expense，I would go abroad now。
但不能说：Weren’t it for the expense，I would go abroad now。
3.用介词短语代替条件状语从句。
常用的介词有with，without，but for。
如：What would you do with a million dollars？（=if you had a million dollars）假如你有一百万美元的话，你会做什么？We couldn’t have finished the work ahead of time without your help。

高考英语 冲刺专题化情态动词和虚拟语气
落堕市安心阳光实验学校高考英语考前冲刺专题强化情态动词和虚拟语气一、几组常见情态动词的含义及用法1．can和could的用法can可以表示能力；表示客观的可能性；表示请示和允许；表示惊异、怀疑、不相信的态度，主要用于肯定句、否定句和疑问句。
表示对现在或将来的推测时，两者均可用，但can通常只用于否定句或疑问句中，一般不用于肯定句，而could则可用于肯定句、否定句和疑问句。
could可表示请求，语气较之can 更委婉，多用于疑问句，其答语应用can。
[典例1] (高考江西卷)It________be the postman at the door.It's only six o'clock.A．mustn't B．can'tC．won't D．needn't[解析] 句意：门口的人不可能是邮递员，现在才六点。
mustn't禁止，不许；can't不可能；won't将不会；needn't不需要。
根据“现在才六点”可知说话者作出“不可能”的推断。
[答案] B点金can的用法集锦1．cannot....to...“越……越好，无论怎样……也不过分”与can never...too 同义。
2．cannot/could not but＋动词原形表示“只有，除……之外别无可能”，cannot help but＋动词原形及cannot help＋动名词表示“不可避免某事”。
3．can/could＋否定词＋动词原形＋形容词或副词的比较级，这一结构形式上是否定的，意义上却强调一种肯定。
如：I couldn't agree more。
2．may与might的用法在表示允许的时候，若表示请求别人允许自己做某事，两者都可用，只是might 表示的语气较委婉；表示自己允许别人做某事，通常要用may而不用might。
在通常情况下，may表示允许(请求允许或给予允许)时，总是针对“现在”或“将来”而言，若要表示已经给予或已经存在的允许，则通常不用may，而用can。
2023年高三英语复习核心知识点情态动词和虚拟语气
情态动词和虚拟语气一、问：本考点旳命题思绪是什么？答：情态动词要注意如下3个方面：1、重视在语言环境中根听说话人旳语气来使用情态动词。
2、情态动词表达推测或判断旳使用方法考察。
3、设置场景考察学生纯熟使用表达责怪等旳情态动词加完毕时旳使用方法等。
虚拟语气是历年高考旳选考考点。
考点常集中在含蓄条件句以及宾语从句中旳虚拟语气上。
所设选项常通过谓语动词旳特殊形式来表达，并且都是结合详细语境来考察对考点旳运用能力。
此后高考对虚拟语气旳命题重点仍会是在特定语境中考察虚拟语气中旳含蓄虚拟条件句、宾语从句中旳谓语动词等。
例1：(08上海卷). According to the air traffic rules, you ___ switch off your mobile phone before boarding.A. mayB. canC. wouldD. should【答案】D。
【题源探究】考察should旳基本使用方法。
【广角思维】句意为“根据航空交通法，有在登机前应当把手机关掉。
”should“应当”符合该句语境因此答案为D。
【易误警示】不能精确地把握该提旳语境是考生在做该题时出现旳重要错误。
做此类试题时一定要通过语境把握准语境体现出来旳说话人旳语气和态度。
【悟彻高考】should旳其中一种重要使用方法是：should 作为情态动词，一般用来表达目前或未来旳责任或义务，译作“应当”、“应当”，这时它可以和ought to，be supposed to 互换使用。
例如：You should （= are supposed to ）complete your test in time.你们应当准时做完你们旳试验。
You should （= ought to ）tell your mother about it at once.【同类预测】对should旳这种使用方法旳考察会比较灵活，也比较常见，有时会运用ought to 来考察该使用方法。

高考英语语法复习情态动词与虚拟语气知识讲解一、情态动词（1）表示能力时，can只用于一般现在时，could仅用于一般过去时；而be able to则有更多的时态，如将来时、完成时等。

高考语法必考点专题复习10--情态动词和虚拟语气
语法考点专题复习（10）---情态动词和虚拟语气【知识框架】[注意]虚拟条件句与主句的谓语动词——与现在事实或将来可能的事实相反，从句用一般过去时(be用were)；与将来可能事实相反时还可用were to/should＋动词原形，主句用would/should/could/might ＋动词原形；与过去事实相反，从句用过去完成时，主句用would/should/could/might have＋过去分词。
1．熟记虚拟语气的三种句型公式(1)表示与现在事实相反的情况(2)表示与过去事实相反的情况(3)表示对将来情况的主观推测2.表示能力，can与be able to一般可互换，但be able to可用于将来时和完成时等更多时态；在表示过去具体某次能够成功做成某事时，只能用was/were able to。
3．表示请求许可，可说May/Might/Can/Could I．..？但表示给予许可时，不能用might/could，即不说you might/could。
4．must强调主观认为“必须”做某事，只有一般现在时态；而have to强调客观上要求“不得不”做某事，有更多的时态变化；mustn't“不准”，而don't have to＝needn't“不必”。
5．表示“应该，应当”，should和ought to可互换，只是ought to的语气稍重；should强调主观看法，而ought to强调客观要求。
6．表示推测的情态动词，若按语气强弱排列，依次有must，can，could，may，might等。
其中，could，might不一定是can，may的过去式，只是语气分别比can，may更弱。
使用时注意以下几点：(1)must只用于肯定句，表示有把握的推测，可译作“一定会，准会”。
(2)can一般不用于肯定句，可译作“可能”；但语气稍弱的could可用于肯定句；can表示“有时也会”时也可用于肯定句。

高考英语考前冲刺专题强化情态动词和虚拟语气一、几组常见情态动词的含义及用法1．can和could的用法can可以表示能力；表示客观的可能性；表示请示和允许；表示惊异、怀疑、不相信的态度，主要用于肯定句、否定句和疑问句。
表示对现在或将来的推测时，两者均可用，但can通常只用于否定句或疑问句中，一般不用于肯定句，而could则可用于肯定句、否定句和疑问句。
could可表示请求，语气较之can更委婉，多用于疑问句，其答语应用can。
[典例1] (2011年高考江西卷)It________be the postman at the door.It's only six o'clock.A．mustn't B．can'tC．won't D．needn't[解析] 句意：门口的人不可能是邮递员，现在才六点。
mustn't禁止，不许；can't不可能；won't将不会；needn't不需要。
根据“现在才六点”可知说话者作出“不可能”的推断。
[答案] B点金can的用法集锦1．cannot....to...“越……越好，无论怎样……也不过分”与can never...too同义。
2．cannot/could not but＋动词原形表示“只有，除……之外别无可能”，cannot help but ＋动词原形及cannot help＋动名词表示“不可避免某事”。
3．can/could＋否定词＋动词原形＋形容词或副词的比较级，这一结构形式上是否定的，意义上却强调一种肯定。
如：I couldn't agree more。
2．may与might的用法在表示允许的时候，若表示请求别人允许自己做某事，两者都可用，只是might表示的语气较委婉；表示自己允许别人做某事，通常要用may而不用might。
在通常情况下，may表示允许(请求允许或给予允许)时，总是针对“现在”或“将来”而言，若要表示已经给予或已经存在的允许，则通常不用may，而用can。
在表示推测的时候，两者都可用，只是might比may语气更不确定，表示的可能性更小。
此外may/might(just)as well“不妨，最好”，其意义与had better相近。
3．must和have to的用法must表示“必须，应该”之意，语气比should，ought to强烈；must be＋doing/adj.表示对现在情况有把握的推测，意为“一定，准是，想必”，用于肯定句中。
其否定形式mustn't 表示“不准，不应该，禁止”等意。
have to“必须，不得不”，意义与must相近。
但must表示的是说话人的主观看法，而have to 则往往强调客观需要；must只有一种形式，即现在式与过去式都是一种形式，而have to则涉及人称、时态等方面的变化。
另外情态动词must表示决心，意思是“一定要”、“坚持”；或表示命中注定或(某事发生的)必然性，意思是“必定会”。
[典例2] —Good morning.I've got an appointment with Miss Smith in the Personnel Department.—Ah，good morning.You ________be Mrs.Peters.A．might B．mustC．would D．can[解析] 此处考查must表示肯定推测的用法。
根据“I've got an appointment wi th Miss Smith in the Personnel Department.”可知，答话者能够肯定地推测出此人就是Mrs.Peters，所以此处要用must。
[答案] B[典例3] You ________buy a gift，but you can if you want to.A．must B．mustn'tC．have to D．don't have to[解析] 从后面的you can if you want to可知“买礼物”这件事可做也可以不做，因此我们可推知前一分句表达的意思是“你没有必要(don't have to)买礼物”。
而mustn't表示禁止做某事，不符合题意。
[答案] D4．shall与should，ought to的用法shall用于第一、第三人称且用于疑问句时，表示说话人征求对方的意见或向对方请示；shall 用于第二、第三人称且用于陈述句时，表示命令、警告或威胁。
should可表示劝告或建议，意为“应该”；表示推测，意为“可能”；表示出乎意料，意为“竟然”；should do表示某种情况是合理的，符合逻辑的，用于第一人称且用于疑问句时表示征询意见。
ought to表示“有义务”或“必要”，含劝告或推测之意。
[典例4] —I haven't got the reference book yet，but I'll have a test on the subject next month.—Don't worry.You ________have it by Friday.A．could B．shallC．must D．may[解析] 根据上文的“Don't worry.”，可知答话者对上文的说话者进行安慰，并且“许诺到周五前能拥有参考书”，此处shall用于第二人称表示许诺。
[答案] B二、虚拟语气在条件句中的使用点金在虚拟条件句中，若有动词were，should或had，有时可以省略连词if，而把这三个词放在主语之前，变成倒装句。
[典例5] Had I known about this computer program，a huge amount of time and energy ________.A．would have been saved B．had been savedC．will be saved D．was saved[解析] 根据句子的倒装特征判断此处是省略了if的虚拟条件句，此句可还原为“If I had known about this computer program，a huge amount of time and energy ________.”。
此处表示与过去事实相反的假设，故A项正确。
句意：如果我早知道这个电脑程序，就可以节省大量的时间和精力了。
[答案] A[典例6] (2011年高考陕西卷)I________ through that bitter period without your generous help.A．couldn't have gone B．didn't goC．wouldn't go D．hadn't gone[解析] 句意：没有你的慷慨帮忙，我不可能熬过那段痛苦的日子。
从without your generous help可知，此处考查的是与过去事实相反的虚拟语气。
故选A。
[答案] A三、虚拟语气在其他从句中的使用1．虚拟语气有时候在假设的情况不是以条件句的形式呈现的，而是用介词without，but for 等或用连词but，or，otherwise等来表示的。
2．表示建议、要求、命令、决定、督促的动词，如suggest，propose，recommend，insist，order，demand，request，advise，command，require，urge等后面的that从句中要用虚拟语气，谓语动词用“should＋动词原形”，should可省略。
但是，当suggest作“暗示，表明”讲时，不用虚拟语气，从句的谓语动词的形式要视情况而定。
insist当“坚持说”讲时，不用虚拟语气，从句的谓语动词的形式要视情况而定。
3．suggestion，order，proposal，demand，request，advice，idea等名词在句中作主语、表语、宾语，并且后面出现表语从句、同位语从句时，从句的谓语要用should＋动词原形，should可省略。
4．wish/if only(要是……就好了)表示不可能实现的愿望，其后用动词的过去式表示与现在事实相反的虚拟语气；用had done表示与过去事实相反的虚拟语气；用could/would/might do 表示将来没有把握或不太可能实现的愿望。
5．as if/as though作“好像”讲，引导方式状语从句，表示一种非真实的情况时，用虚拟语气。
从句中的谓语动词形式与wish/if only后的从句中的谓语动词形式相同。
6．It's(high)time that＋主语＋did/should＋动词原形，表示说话人的建议或愿望。
7．It's necessary/important/strange...that...句式表达了说话者的命令、要求、建议等，从句中谓语应用should＋动词原形，其中should可省略。
8．would rather后跟从句，表示主语“宁愿让某人干某事”时，从句要用虚拟语气，即用一般过去时表示现在或将来要做的事；用过去完成时表示过去要做的事。
[典例7] (2011年高考北京卷)—Where are the children? The dinner's going to be completely ruined.—I wish they________always late.A．weren't B．hadn't beenC．wouldn't be D．wouldn't have been[解析] 句意：“孩子们在哪儿？这顿饭要彻底毁了。
”“我但愿他们不会总来晚。
”从“Where are the children？”可知，说话人指现在。
根据动词 wish 后的宾语从句用虚拟语气的用法可知，表示与现在事实相反的情况时，从句用一般过去时态，因此选项A正确。
[答案] A高考秘笈1．学习和掌握情态动词的意义和用法，应遵循如下步骤：(1)阅读语法参考书，首先从整体上把握情态动词的语法特征和语义特征；(2)逐个学习，了解每个情态动词的用法特征；(3)认真区别具有相同功能的、意义相近的情态动词的用法；(4)收集大量真实的口语材料(如教材中的对话材料及听力材料)，在真实的交际情景中印证和领悟它们的用法和特征。
2．正确分析句子语境历年高考对情态动词的考查都是考查其在具体语境中的运用，只要正确分析语境即可正确选择答案。
3．注意谓语动作发生的时间(1)如果推测过去的情况，情态动词后用完成式；(2)如果推测正在进行的情况，情态动词后用进行式；(3)如果推测现在的情况，情态动词后用动词原形；(4)如果推测将来的情况，用may/might＋动词原形。
