答案以及解析
单句语法填空
1答案及解析：
答案：may/might
解析：句意:他很可能拒绝和你说话,因为他的心情不好。may/might well为固定搭配,意为"很可能,极有可能”。
2答案及解析：
答案：can/could
解析：由 he knew nothing about it 可知,他没有去参加生日会,所以应用can't/couldn’t have done表示对过去动作的否定性推测。
3答案及解析：
答案：must
解析：句意:他们房间里吵吵闹闹的,夫妇俩一定还在争吵。must be doing表示对正在进行的动作的推测,意为“一定在做”。
4答案及解析：
答案：can
解析：句意:对于你的阅读技能你怎么注重都不为过,因为它们是如此的重要。can
not/never…too/ enough…意为“无论怎样……都不过分,越……越好”。too位于所修饰的形容词、副词之前,enough则后置。
5答案及解析：
答案：shall
解析：shall与第二人称搭配表示允诺、强制、命令、威胁、警告等,还可表示在法律条文中的要求或规定。根据句意可知,此处表示允诺的语气。
6答案及解析：
答案：should
解析：由it’ll give me horrible dreams 可知,前句表示 "我本来不该看这部电影的",应使用 "should + 动词完成式”。shouldn’t have d one本不该做(而实际上已做)。
7答案及解析：
答案：must have placed
解析：考查情态动词对过去发生事情的推测,从语意来看是肯定推测,因此用must have done。
8答案及解析：
答案：can
解析：句意:Samuel是我们班里最高的男孩,他可以轻松地够到书架顶层的书。考査情态动词。can意为“可以,能够”,表示能力,符合语境。
9答案及解析：
答案：should have known
解析：考査情态动词。考查句式:should have done 本来应该做某事(但没有做)。句意:作为你最好的朋友之一,我本来应该知道你当时不高兴,但我却不知道。抱歉!
10答案及解析：
答案：would
解析：
考查情态动同。考査will表示习惯性动作的用法.可译为"常常”。"现在常常做某事”用will do 过去常常做某事”用would do sth.。由lived可知本题考査“过去常常做某事”,故用would fish。句意:当居住在加拿大时,我星期天常常在附近的池塘钓鱼。
11答案及解析：
答案：should snow/were to snow/snowed
解析：表示与将来事实相反的愿望,if从句的动词常用did/should do were to do二种形式。
12答案及解析：
答案：would have gone
解析：句意: 上周你去看时装表演了吗?——我本想去的,但我一整周都很忙。由答语but I was fully occupied the whole week可知, “我”没有去看时装表演,故填入would have gone, 表示未曾实现的愿望。
13答案及解析：
答案：had had
解析：句意:在上周举行的英语演讲比赛中,我要是更自信些就好了!在if only "但愿,要是…… 就好了”的句型中,常用一般过去时表示与现在事实相反的愿用过去完成时表示与过去事实相反的愿望。由last week可知，应填入had had。
14答案及解析：
答案：would/should/could/might
解析：句意:是张先生帮我们脱离困境的,要是没有他的帮助,我们不可能这么容易地处理好这件事。题干中用But for his help代替条件状语从句,从时间上看讲的是过去发生的事,所以应用 "情态动词+动词完成式”表示对过去的虚拟。
15答案及解析：
答案：(should) be discussed
解析：句意:他们主张他所反对的那个计划在下次会议上讨论。题干中he was opposed to 为定语从句,修饰plan; advocate意为"主张,倡导",所接宾语从句使用虚拟语气,should可以省略。
单句改错
1答案及解析：
答案：However, if we
stress
stressed
cooperation too much, there would he no progress./
However, if we stress cooperation too much, there would
will
he no progress.
解析：
句意:然而,如果我们过分强调合作,就不会有进步了。本题有两种改法,一种是看作与现在事实相反的假设,这时if条件从句用一般过去时,主句用would do来表示虚拟;第二种改法是使用陈述语气叙述事实,这时if引导的条件状语从句用一般现在时表将来,主句要用一般将来时,故将would改为will.
2答案及解析：
答案：Firstly,I’d like to show my appreciation to those who stand by me all the way, teachers, parents and friends included. Without their help or advice, my
life
will
would
he different.
解析：句意:首先,我要感谢一直支持我的那些人,包括我的老师,父母和朋友。没有他们的帮助和建议,我的人生将会不同。此处without短语表示假设,故该句的谓语动闻应使用would be表示虚拟。
3答案及解析：
答案：In my opinion, by doing part-time jobs, college students must
can
gain some
social experience and broaden their horizons.
解析：
句意:依我看,通过做兼职,大学生们能够积累一些社会经验,并拓宽视野.根据句意可知,这里指“能够”,而非“必须,一定”。
4答案及解析：
答案：Most importantly,all of us must believe in each other and been
be
honest in
our daily life.
解析：句意:最重要的是,大家必须彼此信任.在日常生活中必须诚实。错误处与前面的believe为并列关系.情态动词后需使用动词原形。

高中英语情态动词精讲与解析
高中英语情态动词精讲与解析 概说 助动词(auxiliary)主要有两类：基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。基本助动词有三个：do, have和be；情态助动词有十三个：may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to. 上述两类助动词的共同特征是，在协助主动词构成限定动词词组时，具有作用词的功能： 1）构成否定式： He didn't go and neither did she. The meeting might not start until 5 o'clock. 2）构成疑问式或附加疑问式： Must you leave right now? You have been learning French for 5 years, haven't you? 3）构成修辞倒装： Nowhere can he obtain any information about his sister. Hardly had he arrived when she started complaining. 4）代替限定动词词组： A: Who can solve this crossword puzzle? B: Tom can. A: Shall I write to him? B: Yes, do. 情态助动词的特征 基本助动词与情态助动词最主要的区别之一是，基本助动词本身没有词义，而情态助动词则有自己的词义，能表示说话人对有关动作或状态的看法，或表示主观设想： What have you been doing since? （构成完成进行体，本身无词义） I am afraid I must be going. （一定要） You may have read some account of the matter. （或许已经） 除此之外，情态助动词还有如下词法和句法特征： 1）除ought和used以外，其他情态动词后面只能接不带to的不定式。如果我们把ought

同等学力英语语法专项复习虚拟语气
2013年同等学力英语语法专项复习：虚拟语气 一、总述 虚拟语气（subjunctive mood ）用来表示说话人的愿望、请求、意图、建议、怀疑、设想等未能或不可能成为事实的情况，以及在说话人看来实现可能性很小的情况。由于虚拟语气是动词的一种特殊表现形式，因而动词的变化形式体现出虚拟语气所包含的不同含义。虚拟语气用于非真实条件句时的构成如下表所述： 二、重要考点 1. 在非真实条件句中，有时从句的动词所表示的动作和主句的动词所表示的动作并不同时发生，这样的条件句中使用的虚拟式称为混合虚拟式。其构成视具体情况而定。例如： If I had taken my raincoat when I came out this morning, I would not be wet now. If I were you, I wouldn’t have missed the film last night. 2. 引导非真实条件从句的连词if 在正式文体中有时可以省去, were、had、should 等非行为动词这时应提到从句句首。 例如： If I were you, I wouldn’t feel sorry. →Were I you, I wouldn’t feel sorry. 3. 有些句子从表层结构上看是无if 引导的非真实条件句，但从深层意思上看if 是存在的。这种情况下主句动词仍需用虚拟式。这类句子中常出现without （如果没有），but for （要不是），otherwise （否则），but that （若不，后接一从句）等词或词组。例如： But for your help, they couldn’t have succeeded. She wasn’t feeling well. Otherwise，she wouldn’t have left the meeting so early. 4. 在It is + 形容词 + that 从句的句型中，that 引导的主语从句中的谓语动词采用should + 动词原形形式，其中should 常省略。可用于此句型的形容词还有：absurd, advisable, better, best, desirable, (un)fair, fortunate, good, imperative, important, incredible, just, natural, (un) necessary, odd, pleasant, possible, preferable, right, ridiculous, sad, silly, unusual, urgent, vital, wrong 等，表示必要、应该、建议、要求、惊讶、不相信等含义。例如： It’s necessary that we (should) set out at once. It’s proposed that a committee (should) be set up to look into the matter. 5. 具有“提议、建议、请求、命令”等含义的动词所带的从句（包括宾语从句和主语从句）中，谓语动词用should + 动 词原形形式。美国英语多用动词原形，英国英语多用should + 动词原形。有相同用法的动词还有：ask, advise, agree, arrange, beg, command, decide, demand, desire, determine, direct, instruct, insist, intend, maintain, move, order, persuade, pray, propose, recommend, request, require, stipulate, suggest, tell, urge。如： I suggest that we (should) go camping tomorrow. He insisted that our laboratory reports (should) be handed in
高考英语情态动词专题复习
情态动词精品学案 情态动词解读: ①本身有一定的词义，表示说话人的情绪、态度或语气的动词。 ②不能单独作谓语。 ③和其他动词原形构成谓语。 ④谓语动词之前。 ⑤无人称和数的变化。 ⑥否定式构成是在情态动词后面加“not”。 ⑦个别情态动词有现在式和过去式两种形式，过去式可以用来表达更加客气、委婉的语气，时态性不强，可用于过去，现在或 将来。 经典例句： We can be there on time tomorrow. 我们明天能按时去那儿。 May I have your name? 我能知道你的名字吗？ Shall we begin now? 我们现在就开始吗？ How dare you treat us like that! 你怎么敢那样对待我们! We can't carry the heavy box. 我们搬不动那箱子。 情态动词考点： 1.情态动词表示推测。 2.情态动词的基本用法。 3.情态动词的答语。 1 / 17
常见情态动词： 情态动词有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。 情态动词的基本用法： 一、can, could 1) 表示能力（体力、知识、技能）时，等于be able to 。 a)Can you lift this heavy box?（体力） b)Are you able to lift this heavy box? c)Mary can speak three languages.（知识） d)Is Mary able to speak three languages? e)Can you skate?（技能） 此时可用be able to代替。 2) can表示请求和允许。 -----Can I go now? ----- Yes, you can. / No, you can’t. 此时可与may互换。在疑问句中还可用could, might代替，不是过去式，只是语气更委婉，不能用于肯定句和答语中。（特别注明：这是在表示请求和允许的时候。） ---- Could I come to see you tomorrow? ---- Yes, you can. (No, I’m afraid not. ) can't在否定句中可以表示命令，不允许，但是语气比mustn't弱，具有劝慰的意思. 3)can表示“有时会”： A kind person can lose temper sometimes. 4）表示与五种感官和知觉的动词连用。 I can hear/ see you clearly from here. You can imagine how annoyed she was ! 2 / 17
最新英语语法情态动词归纳总结
最新英语语法情态动词归纳总结 一、单项选择情态动词 1．Mr. Smith is almost on time for everything. How ________ it be that he was late for the meeting? A．can B．should C．may D．must 【答案】A 【解析】 【详解】 考查情态动词辨析。句意：史密斯先生几乎任何事情都是准时的。他怎么可能开会迟到了？ A. can可能，可能性，表示可能性时，常用于否定句和疑问句中，且有时还带有“惊奇、不相信” 等感情色彩。B. should 应该； C. may也许，表示可能性时常用于肯定句中，不用于疑问句中。D.must常用于肯定句中表推测，“一定……”的意思；本题是强调句型的一个变式：强调其特殊疑问句how的形式。根据前句“斯密斯先生几乎是很准时”可推测出“怎么可能开会迟到呢？”。根据句意可知，用于疑问句中的“可能性”且有不相信的色彩，四个选项只有“can”符合题意。故选A 【点睛】 情态动词就是表示说话者对事情的一种看法，也就是一种语气。情态动词的用法一直是命题者常设置的考点和重点，平时要加强记忆。 2．--- Oh, my God! I just missed the last bus back home. --- That’s really bad. I’m sure you ______ it, but you just didn’t hurry up. A．had caught B．could have caught C．could catch D．can catch 【答案】B 【解析】 【详解】 考查情态动词+have done结构。句意：——哦,我的上帝!我刚好错过了回家的末班车。——这是非常糟糕的。我肯定你能赶上，但你就是不抓紧。could have done“本来能做而没有做”。故选B。 3．-- Did Jim come? -- I don’t know. He _______ while I was out. A．might have come B．might come C．must have come D．should have come 【答案】A 【解析】 【详解】 考查情态动词推测用法。句意：Jim来了吗？--我不知道，在我不在的时候，可能来过。根据前文I don’t kn ow.可知，说话者不知道Jim来没来，因此后文推测来过，但是语气很不确定，故可知选A。对过去情况的推测为情态动词+have done，must have done 一定做了某

（一）情态动词常考点 （一）表能力 如：I am starving to death。I can eat two bowls of rice now。 （现在的能力）我快饿死了，现在我能吃两碗米饭。 If you have a good sleep，you will be able to work out this problem。 （将来的能力）如果你好好睡一觉，你将能够解出这道题。 The fire spread through the hotel very quickly but everyone was able to get out。 （过去有能力做并且成功的做了某事）尽管这场大火迅速蔓延到了整个宾馆，但是每个人都能够逃出去。 I could have worked out the problem，but I didn’t。 （过去有能力做但未做）我本来可以解决这个问题，但没有解决。 （二）表推测（可能性） 1.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。所谓客观的（理论的）可能性即并不涉及具体某事是否会发生，此种用法常常可以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（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。如： Accident can happen on such rainy days。 这样的多雨天气有可能会发生事故。（客观的可能性） Peter may come with us tonight，but he isn’t sure yet。 彼得今晚可能和我们来，但他还没确定。（实际可能性，不用can） 2.表示具体事情实际发生的可能性： （1）表示具体事情实际发生的可能性的层次比较

虚拟语气用法详解 一、条件句中的虚拟语气 1. 条件句中虚拟语气的形式 从句中提出一种与客观现实不相符或根本不可能存在的条件，主句会产生的一种不可能获得的结果。条件句中 的虚拟语气根据不同的时间有三种不同的形式。 2. 条件句中的虚拟语气的举例 (1) 将来时的条件句中的虚拟语气。如： If he should go to Qing Hua University, he would make full use of his time. 如果他要上清华大学的话，他就会充分 利用他的时间了。 If he were to come here, he would tell us about it. 如果他要来的话，他会通知我们一声。 (2) 现在时的条件句中的虚拟语气。如： If he were free, he would help us. 要是他有空的话，它会帮助我们的。 If he studied at this school, he would know you well. 如果他在这所学校学习的话，它会对你很熟悉。 (3) 过去时的条件句中的虚拟语气。如： If I had seen the film, I would have told you about it. 我如果看过这场电影，我会把电影内容告诉你了。 If I had got there earlier, I would have met Mr. Li. 如果我早点到那儿，我就会会到了李先生。 3. 运用条件句中的虚拟语气时，须注意的几个问题 (1) 当从句的主语为第三人称单数时，谓语动词若是系动词be 时，可用was 代替were。但在倒装虚拟结构及if I were you, as it were 中，只能用were。如： Were I ten years younger, I would study abroad. 要是我还年轻十岁的话，我会去国外学习。 If I were you, I would try my best to grasp the chance. 要是我是你的话，我要尽力抓住这次机会。 (2) 有时，虚拟条件句中，主、从句的动作若不是同时发生时，须区别对待。①从句的动作与过去事实相反，而主句的动 作与现在或现在正在发生的事实不符。如： If I had worked hard at school, I would be an engineer, too. 如果我在学校学习刻苦的话，我现在也会使工程师了 If they had informed us, we would not come here now. 如果他们通知过我们的话，我们现在就不会来这里了。

英语语法总结：情态动词的使用
英语语法总结：情态动词的使用 情态动词的使用 1）情态动词can（能够），must（必须），may（可以）结构：主语+can/must/may+动词原型 He can make the tea. Sally can air the room. We can speak English. ★变疑问句将情态动词移到句首 Can he make the tea? Can Sally air the room? Can we speak English? ★变否定句在情态动词后面加not
He cannot make the tea. Sally cannot air the room. We cannot speak English. ★肯定回答及否定回答 Yes, he can. / No, he cannot. Yes, she can. /?No, she cannot. Yes, we can. / No, we cannot. ★特殊疑问句：（必背） What can you do? 注意：情态动词的句子没有第三人称单数的变化，不要在情态动词或动词后面加s。
2）must/have to的区别 must 表示必须，是主观上觉得应该做，have to是不得不，是由于客观条件逼迫的必要要做 must 只能用在表示现在和将来的句子里，而have to do可以用在任何时态 3）must, may, might表示猜测： ·must do 表示对现在事实的猜测 ·must have done表示对过去事实的猜测 ·must have been doing 表示对过去正在进行的事实的猜测 ·may/might do, may/might have done表示没有任何事实依据的猜测，might的可能性更小。 4）can't/couldn't 表示不可能
高考英语情态动词讲解
（一） 情态动词常考点 （一） 表能力 can be able to will be able to could was/ were able to could have + ?? ???? ?? ?????? ?表示现在的能力 ：表示将来的能力 表示过去的能力 过去分词：表示过去有能力做但未做 如：I am starving to death 。I can eat two bowls of rice now 。 （现在的能力）我快饿死了，现在我能吃两碗米饭。 If you have a good sleep ，you will be able to work out this problem 。 （将来的能力）如果你好好睡一觉，你将能够解出这道题。 The fire spread through the hotel very quickly but everyone was able to get out 。 （过去有能力做并且成功的做了某事）尽管这场大火迅速蔓延到了整个宾馆，但是每个人都能够逃出 去。 I could have worked out the problem ，but I didn ’t 。 （过去有能力做但未做）我本来可以解决这个问题，但没有解决。 （二） 表推测（可能性） 1. 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。所谓客观的（理论的）可能性即并不涉及具体某事是否会发生，此种用法常常可以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（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。如： Accident can happen on such rainy days 。 这样的多雨天气有可能会发生事故。（客观的可能性） Peter may come with us tonight ，but he isn ’t sure yet 。 彼得今晚可能和我们来，但他还没确定。（实际可能性，不用can ） 2. 表示具体事情实际发生的可能性： （1）表示具体事情实际发生的可能性的层次比较 （2）表示具体事情实际发生的可能性时，may ，must 常用于肯定句，一般不用于否定句和疑问句（may not 表示“可能不”）；can 常用于否定句、疑问句或感叹句中，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。如： This can ’t/ couldn ’t be done by him 。（表不相信） 这不可能是他做的。 This may not be done by him 。（表不确定） 这可能不是他做的。 He could be on his way home now 。（could 不如may/ might 常用） 他现在可能在回家的路上。 Can this be done by him ？（表示疑惑、惊讶） 这可能是他做的吗？ Mr. Bush is on time for everything 。How can it be that he was late for the opening ceremony ？（表示疑惑、惊讶） 布什先生做每件事都很按时。他怎么可能在开幕仪式上迟到呢？ I didn ’t hear the phone 。I must have been asleep 。（表肯定） 我没听到电话。我肯定已经睡着了。 3. would ，could ，might 并不一定与过去时间有关，而是表示可能性弱于他们相应的现在时形式。另外should 也不一定与过去时间有关。如： This may/ might be done by him 。（后者比前者语气弱）
高中英语语法讲解与练习之情态动词
高中英语语法之情态动词 （一）情态动词的定义：情态动词表示说话人对某一动作或状态的态度。 （二）情态动词的特点：1）有一定词义；2）不受主语人称和数的变化影响；3）与主要动词的原形（或称不带to的不定式）一起构成谓语（除ought to作固定词组看待）。 情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加"not"。个别情态动词有现在式和过去式两种形式, 过去式用来表达更加客气, 委婉的语气, 时态性不强, 可用于过去，现在或将来。情态动词属非及物动词，故没有被动语态。 He could be here soon. 他很快就来。We can't carry the heavy box. 我们搬不动那箱子。 除此之外，情态助动词还有如下词法和句法特征： 1）除ought和used以外，其他情态动词后面只能接不带to的不定式。 ; We used to grow beautiful roses. I asked if he would come and repair my television set. 2）情态助动词在限定动词词组总是位居第一：They need not have been punished so severely. 3）情态助动词用于第三人称单数现在时的时候，没有词形变化，即其词尾无-s形式： She dare not say what she thinks. 4）情态动词没有非限定形式，即没有不定式和分词形式，也没有相应的动名词： Still, she needn't have run away. 5）情态助动词的“时”的形式并不是时间区别的主要标志。在不少场合，情态助动词的现在时和过去时形式都可以表示现在、过去或将来时间： Would you mind very much if I ask you to do something? She told him he ought not to have done it. | 6）情态助动词之间是相互排斥的，即在一个限定动词词组中只能出现一个情态助动词，但有时却可以与have和be 基本助动词连用：You should have washed the wound. Well, you shouldn't be reading a novel. （三）情态动词有四类：①只做情态动词：must,can(could),may(might),ought to ②可做情态动词又可做实义动词：need,dare ③可做情态动词又可做助动词：shall(should),will(would) ④具有情态动词特征：have(had,has) to,used to ⑤情态动词表猜测 （四）情态动词的基本用法 1. can (could) 1）表示能力，could主要指过去时间。 Two eyes can see more than one. Could the girl read before she went to school? 这女孩上学前能识字吗？ ' 2）表示可能（理论上或是逻辑判断上）。 The temperature can fall to –60℃, that is 60℃ below freezing. 气温可降至—60℃，也就是零下60℃。 He can′t (couldn′t) have enough money for a new car. 他不可能有足够的钱买新车。 3）表示允许。 Can I have a look at your new pen? 我可以看一看你的新钢笔吗？ He asked whether he could take the book out of the reading—room. 他问他可不可以把书带出阅览室。 4）表惊异、怀疑、不相信等态度。主要用于否定句、疑问句或感叹句中。 Where can (could) they have gone to? 他们会去哪儿了呢？He can′t (couldn′t) be over sixty. 他不可能超过六十岁。 《 5）比较委婉客气地提出问题或陈述看法。 Can (Could) you lend me a hand? I′m afraid we couldn′t give you an answer today. 恐怕我们今天不能给你答复。
