情态助动词
情态动词讲练
情态助动词表示推测，可能性，允许，能力等用法，情态助动词与完成时连用。
（一）情态动词的特征 特征（二）情态动词的基本用法 1．can和could的用法
特别说明：①could可表示请求，语气委婉，主要用于疑问句，不能用于肯定句，答语应用 can（即：could不能用于现在时态的简略答语中）。如：——Could I use your bike tomorrow morning?——Yes, you can.（否定回答可出：No, I’m afraid not.）②惯用形式“cannot…too…”表示“无论怎么……也不（过分）”。如： You cannot be too careful.（你越小心越好。） 惯用形式：“cannot but+不定式（不带to）”表示“不得不，只好”。如：I cannot but admire your bravery. 我不得不钦佩你的勇气。I could not but choose to go. 我不得不去。（我只好去）。③can与be able to都表示能力，在意义上没有区分。 但can只有现在式和过去式（could），而be able to则有更多的形式。如： 过去时：was/were able to将来时：will be able to 完成时：have/has been able to如果要表达将来的能力时，一般要用be able to. 如：I’ll be able to speak French in a few months.用be able to的过去式was/were able to表示在过去某时的某一场合设法做成了某事，相当于managed to do,而could则无此意义。如：The fire was very big, but most people were able to escape from it. 2．may与might的用法
说明：may as well 还是……好。如：We may as well stay where we are. 我们留在现在的地方倒也不错。You may as well tell me the truth. 你还是把真相告诉我的好。 3．must和have to的用法
4．shall与should的用法情态动词 用法 例句 用于第一个称，表示征求对方的意愿 What shall we do next? 用于第一、第三人称疑问句中，表示说 话人征求对方的意见和向对方请示
用于第二、第三人称陈述句中，表示说 话人给对方的命令、警告、允诺加顿号 “、”威胁 Shall we begin our lesson? Shall the driver wait?When shall my farther be able to leave hospital?You shall go with me.（命令）You shall have the book when I finished it.（允诺）He shall be punished. (威胁) 用于表示劝告的建议，作“应该”讲 We should be strict withourselves.You should keep your promise. 用于表示推测，译为“可能”或“该”讲 They should arrive by two o’clock. 用于第一人称时可表示说话人的一种谦 逊、和气、委婉的语气
还可以用在if引导的条件从句中，表示一 件事听起来可能性很小，但也不是完全 不可能。相当于“万一”的意思。从句谓 语用should加动词原形构成，主句都不 一定用虚拟语气
Why/How+should结构表示说话人对某 事不能理解，感到意外惊异等意思，意 为“竟会” I should advise you not to do that.（我倒是劝你是别这样做。）You are mistaken, I should say.（依我看，你是搞错了。）Ask Tom to ring me up if you should see him.（你万一见到汤姆，请你让他给我打 个电话。）Should I be free tomorrow, I’ll come.（万一我明天有时间，我就过来。） If things should change suddenly, please let me know.（万一情况突变，请通知我。）Why should you be so late today?（你今天怎么来的这么晚？）I don’t know why you should think that I did it.（我真不明白你凭什么认为这件事是 我干的。） 5．will与would的用法
说明：would与used to之区别：would可用来表示过去反复出现的动作，但不能表示过去存在的状态，所以我们不 能说：”She would be a quiet girl.”而used to则着眼于过去和现在的对比，隐含现在已不 复如此之意，动作或状态都可表示。如：He used to be a naughty boy. He used to make a lot of troubles. 他过去是个淘气的孩子，总是惹很多麻烦。 6．need与dare的用法
7．ought to的用法
说明：should与ought to表示“应该”时的区别：should表示自己的主观看法，而ought to语气重，含有“按道理应该…”之意，如要 反映客观情况或涉及法律义务和规定时一般用ought to。如：You should help them with their work.You are his father. You ought to get him to receive good education. （三）“情态动词+have done”的用法情态动词+不 定式完成式 用法 例句 must have done
can have done
could have done
may/might have done
might have done
should/ough t to have done
needn’t have done
had better have done 表示对过去已经发生的行为进行 推测，意为“想必/准是/一定做了 某事”
表示对过去发生的行为的怀疑和 不肯定，通常用在否定句和疑问 句中可用于肯定句中，表示“可能已 经……”之意，此外，还可以表示 过去没有实际的可能性， 意为 “本来可以…” 表示对过去已发生行为的推测， 意 为 “ 也 许 / 或 许 / 已 经 （ 没 有）…”。一般只用于肯定句或否 定 句 中 ， 不 用 于 疑 问 句 。 用 might则表示语气更加不肯定 表示“本来可能……”，但实际上没 有发生的事。另外，还可以表示 “本来应该或可以做某事”之意， 含有轻微的责备语气用于肯定句时，表示“本该做某 事”，而实际上未做；用于否定 句时，则表示不该做的事反而做 了
表示做了本来不必去做的事注 意：didn’t need to do表示“没 必要做而实际上也没有做某事”
用于事后的建议，含轻微责备的 口 吻 ， 意 为 “ 当 时 最 好 做 了 某 事”，其否定式had better not It must have rained last night, for the road was quite muddy.The lights were out. They must have been asleep.He cannot have forgotten it. Can he have gone to his aunt’s?
You could have done better, but you were too careless.I saw Mr. Wang just now. He couldn’t have gone to Beijing.It’s too late. I think he may have gone to bed.He may not have finished the work. She might have caught a cold.
You should not have swum in that sea. You might have been eaten by fish.You might have given him more help, though you were busy.You should have come to the meeting earlier.You ought to have done this exercise more carefully.You shouldn’t have told her the truth/He ought not to have treated his parents like that.You needn’t have taken a taxi here, for it was very near to my house.I didn’t need to clean the windows. My brother did it.You had better have started earlier. You had better not have scolded her.

点击典型、易错试题(一)同类词语意义不清[考题1]---Isn’t that Ann’s husband over there?---No，it __be him．I'm sure he doesn’t wear glasses．A．can’t B．must not C．won’t D．may not 解题思路：句意：---那边那个人不是Ann的丈夫吗?一不是，不可能是他。我确信他是不戴眼镜的。can用于否定句表示怀疑和否定。 答案：A易错警示：切记must not／may not表禁止，must／will只能用于肯定句，表示有把 握的推测。[考题2]I often see lights in that empty house．Do you think I __report it to the police?A．should B．may C．will D．can 解题思路：句意：我经常看到那座空房子里有灯亮。你认为我应该把这件事向警局报告吗?should和will分别用于第一人称和第二人称疑问句，表示征询意见。 答案：A易错警示：can／may用于疑问句则表示请求允许。can多用于口语中，may较正式。[ 考 题 3]“The interest be divided into five parts ， according to the agreement made by both sides，”declared the judge．A．may B．should C．must D．shall 解题思路：句意：法官宣布，“根据双方达成的协议，利息应分成五部分”。shall在条约、规章、法令等文件中表义务或规定，一般用于第三人称，表示“必须／应”。 答案：D 易错警示：must和should都表义务／责任，意为“应该／当”；may表允许。[考题4]A left-luggage office is a place where bags be left for a short time，especially at a railway station．A．should B．can C．must D．will 解题思路：句意：行李寄存处是可以短时存放行李的地方，尤其设在车站处。can表允许；should／must表责任；will表意愿。 答案：B 易错警示：容易忽视can表允许这一层意思。[考题5]I should have been there，but I _not find the time． A．would B．could C． might D．should 解题思路：分析题意可知第二个分句表示过去的某种能力，故本题选B。 答案：B易错警示：C项只表示语气上的可能性，与题意不符。[考题6] The fire spread through the hotel very quickly but everyone __get out．A．had to B．would C．could D．was able to 解题思路：该题考查了could和be able to的区别，二者都可表示过去时间的能力，但如果表示过去成功地做了某事只能使用was／were able to do。 答案：D易错警示：容易忽略can与be able to的区别。 (二)语境理解错误[考题7]---Tom graduated from college at a very young age.---Oh，he _have been a very smart boy then． A．could B．should C．might D．must解题思路：句意：—Tom年纪轻轻的就大学毕业了。—哦，他当时一定是个很聪明的 孩子。must have done是对过去的肯定推测。答案：D易错警示：should have done表示所期望的动作未完成，作“本应该”解；could have done／might have done表示“本来能够／可以”，都是可能性较小的推测。[考题8]---I’ll tell Mary about her new job tomorrow．---You her last week．A．ought to tell B．would have told C．must tell D．should have told 解题思路：句意：—我明天将要告诉Mary有关新工作的事。—你本应该上周就告诉她的。should have done表示所期望的动作未完成，作“本应该”解。 答案：D。易错警示：ought to／must do表“应当／必须”，指现在或将来；would have done 表“本来要／会”。[考题9]---Who is the girl standing over there?---Well，if you _know，her name is Mabel． A．may B．can C．must D．shall解题思路：句意：一站在那边的女孩是谁?—哦，如果你一定要知道的话，那我就告 诉你她叫Mabel。may／can表允许，“可以”；if you must do sth.(表示虽不赞同但可允 许)如果一定要那么做；shall用在表意图、要求的从句中，有“应该／要”之意。答案：C 易错警示：情态动词的选择也要结合语境分析。[考题10]---Excuse me，but I want to use your computer to type a report．---You have my computer if you don’t take care of it． A．shan’t B．might not C．needn’t D．shouldn’t解题思路：句意：—对不起，我想用你的电脑打一篇报告。—如果你不把我的电脑照 管好，你就不能借。shan’t=shall not。shall用于第二、三人称中，表说话者的意图、允 诺、警告、命令、决心等。答案：A易错警示：might not也表不可以，但语气过分委婉；needn’t表不必；shouldn’t表 不该。[考题11]---Is John coming by train?---He should，but he _not．He likes driving his car． A．must B．can C．need D．may解题思路：come，go，leave，start等趋向动词的进行时表示将来时，所以答语是对 这一将来动作作出的推断。may not“可能不；不一定”，根据he likes driving his car可以看出John可能乘火车来，也可能自己开车来。may not正好符合这一语境。must not“不 准”；can not“不可能”；need not“不必”。答案：D易错警示：容易错选B，但can not表不可能。 [考题12]---Shall I tell John about it?---No，you ．I’ve told him already．A．needn’t B．wouldn’t C．mustn’t D．shouldn’t 解题思路：情态动词shall在试题中表示征询对方意见或请求指示。答句暗示“没有必要了”，故本题选A。 答案：A易错警示：注意上下文语境的提示。[考题13]---Mum，I’ve been studying English since 8 o’clock．_ I go out and play with Tom for a while?---No, I’m afraid not．Besides，it’s raining outside now．A．Can’t B．Wouldn’t C．May not D．Won’t 解题思路：句意：---妈妈，我从8点开始一直在学英语。难道我不可以出去和Tom玩一会吗?---不可以，恐怕不行。而且外面现在正下着雨。can表许可或请求，will／would 表意志、意愿、建议，意为“愿／要”。答案：A 易错警示：can用在口语中，代替may／might，作“可以”讲。举一反三1．A left-luggage office is a place where bags be left for a short time, especially at a railway station．A．should B．can C．must D．will2．How you say that you really understand the whole story if you have covered only part of the article?A．can B．must C．need D．may 3．---The room is so dirty． _ we clean it?---Of course．A．Will B．Shall C．Would D．Do 4．Naturally，after I told her what to do，my daughter go and do the opposite!A．may B．can C．must D．should 5．My English-Chinese dictionary has disappeared．Who have taken it?A．should B．must C．could D．would 6．Look at the trouble I am in!

必会基础题： 选择题：1．D．have to 表示喜欢的需求。昨天是过去时。排除A、B两项。C是错项应写成 must have + finished.2．A．表示推测，推理用法时must只用于肯定句否定句由can't表示。 3．B．征求对方意见时，主语是you，应用Can you …? Could you / will (would)you?4．C．can回答could所指出的问题。5．B．could have gone本应该坐公共汽车去但实际是走着去的。ought后要加to have gone或should have gone均可作为答案。D项表示的时态与上句不符合。6．B．should have kept表示本应该遵守诺言，（实际未做），带有责备的语气，和下 文change his mind语气一致。7．B．need+名词，need是行为动词，否定句应加上助动词do（ does或did）+ not。8．A．shall用于第一人称I，we前，构成向对方征求对方意见的问句。 9．B．do替代like，避免重覆。10．B．at the moment应用现在进行时态。must be doing意为“一定正在做某 事”。11．C．must have forgotten一定忘记拿钥匙。12．C．should have given表示本应该多浇些水（实际没有浇）。 13．B．might have seen him. 大概会见到他。14．D．B项，don't need后加to come也可作为答案，needn't + do，need是情态 动词。15．D．针对must提出的问题可用，needn't, don't have to, don't need to作为答 语 。16．B．can用于表示疑问的推测句中，may用于肯定句和否定句，must只用于肯定句。17．B．shall用于第二人称，译为“应该”。18．A．had better + not do sth.，have+宾语+done中宾语与done是动宾关系。 单句改错：1．would→should order that 同位语从句中不用would，可用should 或省去 should。2．go→went time后面的从句中应用一般过去时态。 3．attended前加had与would have done相呼应，从句应用had done。 4．need→needs He need do sth. 是情态动词，He needs to do sth.是行为动词。5．not→do have to do的否定或是do not have to do sth. 6．去掉to would rather后只加do的形式。7．get→to get 句首有Does在need后必加to。 8．mustn't→needn’t 反意问句不出现mustn't。 9．ought→ought to ought to + do sth.。 10．will→May 第一人称应用shall I或May I...?
提高拓展题：1．A．从句中was是过去时态，应用A、C，may或might + have done表示对过去 事物的推测，might have done表示可能性更小些。might do或may do应用在目的状语 从句中。He got to the station on time in order that he might (could) meet him. 可 以看出might meet隐含过去将来时态。2．A．must be told是现在时态，can't是“不会、不可能”，may not是“大概不”之意。3．B．would rather是“意愿”的意思，其余三项均为错项。4．C．回答could I (you) do sth.？的问题应用：You can 或I can, can为真实句。 5．C．从but后分句给出无把握的情景句，应用may（大概）的意思，也表示无把握之意与下面句子相呼应。 6．A．but后meant是过去时态，前面分句也应用过去时态，ought not to havetold表示过去事不应该告诉（实际已说出）这一事实。7．A．从句子给出的信息（I've told him already），可以判断出应用needn't “没有 必要”。8．C．told暗示该句是过去时态。but也应用过去时态A、B、C都是过去时态，A、B 项与上面分句意思不顺，C项与but和perhaps语气一致：should have written一我本应 该写出（实际没有写出的意思）。9．D．该句were提供是过去时态，A、B表示现在或将来时态。must表示推测，推理 用法中must不用否定句。10．C．it's提示该句是现在时态should be是将来时意为他应该随时到达。11．B．mustn't 是“禁止、绝对不许”之意。may hurt是大概会伤害你自己。对没有 十分把握的事应用may。12．D．was able to do表示过去通过努力达到的目标的能力。 13．A．could have stayed表示过去本可以做某事而实际没有做 。14．B．15．B．I can't 表示我不能够，后面说明了原因I won't 是我不去。 16．D．I'm not sure 是无把握的意思。might go意为“大概会去”17．C．祈使句隐含将来时态，应用将来时的助动词回答，I will意为我（将）会写的。18．B．shouldn't have left指本不应该做但实际上做了的事。
