II.情态动词的重点知识
表示“能力、许可”的can和may
表示能力的情态动词用can/could
A computer _____ think for itself; it must be told what to do.
A. can’t
B. mustn’t
C. may not
D. might not
表示许可时用may/might ,can/could 都可以，但在问句中用could…?或might…？以使口气委婉客气，其回答一定要用can或may，以使回答口气明确（must表示一定，必须，mustn’t表示禁止，不许可）。
①—Could I call you by your first name? —Yes, you______
A. will
B. could
C. may
D. might
②Johnny, you _____ play with the knife, you _____ hurt yourself.
A. won’t/can’t
B. mustn’t/may
C. shouldn’t/must
D. can’t/shouldn’t
在肯定句中could不可以用来表示过去某一特定场合的能力，而要用was/were able to。

Everyone _____ get out.
A. had to
B. would
C. could
D.was able to
表示“推断、判断”的can
may,must
在肯定句中都可以用来表示可能。在含义上must语气最肯定,may表示的是事实上的可能性。
Peter ______ come with us tonight, but he isn’t very sure yet.
A. must
B. may
C. can
D. will
而can表示的是逻辑上的可能性：
Mary is in poor health. She can be ill at any times.
在否定句中只能用can和may。所以can’t时用以代替mustn’t，语气比may更肯定。中文可以翻译为不可能。
Michael ______ be a policeman, for he’s much too short.
A. needn’t
B. can’t
C. should
D. may
在疑问句只能用can，不能用may和must。
He may be very busy now.
Can he be very busy now?
He must be very busy now.
Can he be very busy now?
need
need作为情态动词只有一种形式，只用于否定句和疑问句。
dare
dare作为情态动词用时有两种形式：dare和dared两个词形，除了可以用于否定句和疑问句外，还可以用于条件从句或表示怀疑的句子中。
If he dare come, I will kick him out. I don’t know whether he
dare say.
注意:He doesn’t dare(to)answer the question.（否定句）
Does she dare(to)enter the dark room?（疑问句）
shall
用于第一人称：征求对方的意见。
What shall we do this evening?
用于第二、三人称：警告、命令、允诺、威胁等。
You shall fail if you don’t work harder. 警告
He shall have the book when I finish reading.允诺
He shall be punished.威胁
should
劝告、建议、命令、应该做、道义上的责任。
You should(ought to) go to class right away.
I should(ought to) help him because he is in trouble. will/ would
请求、建议，would比will委婉客气。
Would you pass me the book?
表示意志、愿望和决心。
I will never do that again.
They asked us if we would do that again
would可表示过去反复发生的动作或某种倾向。
During the vacation he would visit me every week The wound would not heal.（伤口老是不能愈合）
would表示估计或猜想。
It would be about ten when he left home.
What would she be doing there?
情态动词+have done的用法
could+have done：本可以做而实际上未能做。
You could have done better, but you didn’t try your best.
cannot+ have done：表示对现在或过去行为的否定推测。
He cannot have been to that town.
can+主语+ have done：表示对过去行为的怀疑或不肯定（用在疑问句中）。Can he have got the book?

(完整版)虚拟语气的用法及专项练习题[1]
虚拟语气的用法及专项练习题 虚拟语气表示一种假设的情况，或一种主观的愿望，即动词所表示的动 作或状态并非事实，或不可能实现。英语虚拟语气的形式有下列几种： 一.虚拟语气用于条件状语从句 注意:主句中的should 通常用于第一人称,would 可用于任何人称,同时 也可根据意思用情态动词could,might 等代替should,would 。 If I were you, I would give up drinking immediately. country. 3.与将来事实相反 If it were to/should rain tomorrow,the meeting would be put off. If you went there next time, you would see what I mean. 4.错综时间虚拟语气 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来调整。例如: If I were you, I would have gone home.
If you had followed the doctor's advice,you would be quite all right now.(从句说的是过去,主句指的是现在。) If the weather had been more favorable ,the crops would be growing still better. 状语从句 1. 方式状语as if(as though) 如果从句表示与现在事实相反,谓语动词用一般过去时;表示与过去事实相反,谓语动词用"had+过去分词";表示与将来事实相反,谓语动词用"would(might,could)+动词原形"。例如: He looks at me as if I were mad. He spoke English so fluently as if he had studied English in England. 但as if(as though)后的从句也常用陈述语气,这是因为从句中的情况往往是可能发生的或可能被设想为真实的。例如: It looks as if our side is going to win. 2.目的状语in order that,so that 从句谓语动词用" may/might,can/could)+动词原形"。例如: She listened carefully in order that she might discover exactly what he wanted. 3. 连词引导的条件状语从句: in case , unless ,supposing ,providing,on condition that从句谓语动词用(should)或" might, could)+动词原形"。 4. 连词引导的步状语从句: lest ,for fear that等 We hid behind some bushes for fear that passer-by should see us. 二.虚拟语气用于宾语从句 注意：在此结构中that不可省略；should省不省均可。 He suggested that they (should ) stop smoking. They demanded that the black people should be treated as well as white people. 如果that 引导的从句所表达的内容是事实，也可用陈述语气。 He insists that he is right.
情态动词与虚拟语气
情态动词与虚拟语气 【语法要点】 情态动词 所谓情态动词是指它含有一定的含义，可以表达某种感情和说话的语气，但是它不可以单独使用 作谓语动词。学习情态动词主要学习英语国家的语言习惯和表达法，特别是在口语中不要过分追求原理，更不要不根据说话场合而进行推理，编造出一些语法结构正确的中文式英语。 一、情态动词的类型 1.只作情态动词的有：must、can、could、may、might、ought to 2.既可作情态动词又可作实义动词的有：need、dare 3.既可作情态动词又可作助动词的有：shall、should、will、would 二、情态动词的特征 1.表示说话人的情感态度，不能单独作谓语，与行为动词或连系动词一起作谓语。 2.情态动词没有人称和数的变化，后接动词原形。 3.具有助动词的特征：可用来构成否定句、疑问句或简短答语。 三、情态动词的用法 1.表示能力 （1）表示现在的能力，用can 或be able to。表示一般的能力时多用can，表示“经过努力成功 的做成某事”用be able to。 （2）表示过去的能力，用could或was/were be able to。区别同上。 （3）表示将来的能力，用will be able to。 2.表示推测、可能性 （1）can 用在肯定句中表示客观的可能性，而不表示具体事情实际发生的可能性。 例如：Accidents can happy on such rainy days. （2）表示具体事情实际发生的可能性的情态动词，其表示可能性的层次如下表： 情态动词肯定式否定式疑问式 must 必定、必然、一定 will 很可能、大概不会、不该会,,吗？ would 可能性较will 小不会、不该（较won’t 弱）会,,吗？（较will 弱） should 应该会、理应（表示合乎理想的情况或结果） ought to 与should 同义 can 一定不会、不可能（否定推测）有可能吗？ could 可疑的可能不可能（与can’t 同义）有可能吗？（较can 弱）may 或许、可能、说不定可能不 might 或许、可能（较may 弱）可能不（较may not 弱） 注意→（1）may，must 常用于肯定句，一般不用于否定句和疑问句。 （2）can 常用于否定句，疑问句和感叹句中，表示疑惑、惊讶或不相信等意思。could 既可用于肯定句，又可用于否定句、疑问句中。

虚拟语气的用法及经典练习题(附答案)
虚拟语气
概念
虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通 过谓语动词的特殊形式来表示。英语中的语气分为陈述语气、祈使语气、虚拟语气三类。
应用条件 在表示虚假的、与事实相反的或难以实现的情况时用虚拟语气，表示主观愿望或某种强 烈情感时，也用虚拟语气。即当一个人 说话时欲强调其所说的话是基于自己的主观想法，而不是根据客观实际，就用虚拟语气。 在非真实条件状语从句中的用法 真实条件状语从句与非真实条件状语从句 条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设或实际可能性不大的情况，故 采用虚拟语气。 例： If he doesn’t hurry up, he will miss the bus. 如果他不快点，他将错过巴士。 ( 真实 ) If he is free, he will ask me to tell stories. 如果他是空闲的，他会要求我讲故事。 （真实） If I were you, I would go at once. 如果我是你，我马上就会去。 （非真实，虚拟语气） If there were no air, people would die. 如果没有空气，人就会死亡。 （非真实，虚拟语气） 用法及动词形式

虚拟语气专项练习经典
虚拟语气专项练习经典 一、初中英语虚拟语气 1．–I argued with my best friend. What should I do? --If I ________ you, I would say sorry to her. A．am B．was C．are D．were 【答案】D 【解析】试题分析：句意：我和我最好的朋友吵架了。我该怎么办？如果我是你，我就对她说对不起。虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。在虚拟条件语气句中，表示与现在事实相反的事实，条件从句中的谓语动词用过去式（be用were不用was），主句谓语动词为“would+原形动词”，所以选D。 考点：考查虚拟语气。 2．If I not so busy ,I with you . A．was , would go B．were , would go C．was , should go D．were , will go 【答案】B 【解析】句意“如果我不忙，我就跟你去”。本题考查对将来的虚拟语气。即“if+过去时，主语+should/would/could/might do”结构。故选B。 点睛： 3．If I ___ you, I ___ be afraid . A．was, wouldn’t B．were, won’t C．were, wouldn’t 【答案】C 【解析】 试题分析：根据语境可知此句的含义是如果我是你，我就不害怕。考查的是虚拟语气的基本用法。条件用过去时，主句要用过去将来时，故选C。 考点：虚拟语气 点评：虚拟语气其实就是if引导条件状语从句时，词义为“如果”，不过这个条件是无法实

复习专题虚拟语气专项练习题及答案
复习专题虚拟语气专项练习题及答案 一、初中英语虚拟语气 1．–I argued with my best friend. What should I do? --If I ________ you, I would say sorry to her. A．am B．was C．are D．were 【答案】D 【解析】试题分析：句意：我和我最好的朋友吵架了。我该怎么办？如果我是你，我就对她说对不起。虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。在虚拟条件语气句中，表示与现在事实相反的事实，条件从句中的谓语动词用过去式（be用were不用was），主句谓语动词为“would+原形动词”，所以选D。 考点：考查虚拟语气。 2．If I you, I give it to Microsoft research. A．am, will B．am, would C．were, would D．was, would 【答案】C 【解析】 【详解】 句意：如果我是你，我会把它交给微软研究部。 考查虚拟语气。根据If I you，这是一个虚拟语气，此句虚拟语气表示一种不能实现的假设，即与现在事实相反，谓语动词用过去式；该语法主要用于if条件状语从句，本句“如果我是你”，be动词用were，后面主句用过去将来时would＋动词原形，故答案选C。 3．I suggest that we Chinese people_______Chinese culture with love and joy everywhere we go. A．spread B．spreading C．to spread D．will spread 【答案】A 【解析】 【详解】 句意：我建议我们中国人无论走到哪里都要带着爱心和欢乐来传播中国文化， 考查动词suggest后跟虚拟语气。spread是动词原形；spreading是动名词；to spread是动词不定式；will spread是一般将来时。动词在这里suggest表示建议，后面宾语从句中使用虚拟语气should+动词原形，should可以省略。根据句意说明本句的suggest表示建议，故后面使用虚拟语气，省略了should，故选A。 【点睛】 动词suggest 后面可以跟名词作宾语，用于句型“suggest sth.”。如：I suggested a visit. 我提议参观。 suggest 后跟动名词作宾语，如：He suggested going home. 他提议回家。 suggest后面跟that引导的宾语从句时，用虚拟语气，一般省略情态动词should，所以本题选项是A。
