情态动词讲解及练习(有答案)
情态动词讲解及练习一、can和could特别说明：（1）could用来表示请求时，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 dictionary?——Yes, you can.(否定回答可用：No, I’m afraid not.)(2)can和be able to辨析can(could)和be able to都可以表示能力，意思上没有区别。
但can只有现在式和过去式，而be able to则有更多的形式。
如：I’ve always wanted to able to speak fluent English.Those bags look really heavy, are you sure you’ll be able to carry them on your own?但是，表示在过去某时的某一场合经过一番努力，终于做成了某事，通常不用could，而用was/were able to来表示。
这时，was/were able to相当于managed to do或succeed in doing。
如：After the accident it was a long time before she was able to walk again.The fire was very big, but most people were able to escape from the building.(3) 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 her determination.我不得不钦佩你的决心。

句意：虽然这并不是这次旅行的目的，但我得到了一些新的领悟，那些领悟在我的日常生活中是本不可能发生的。
此处考查虚拟语气，“我得到新的领悟”发生在过去，故此处是与过去事实相反，应用could/might/would/need/should+have done，“本不可能发生”是could never have happened，故选B项。
【点睛】本题考查“情态动词+have done”的虚拟语气，其常用表达有：could have done本能做某事而未做couldn’t have done不可能做了某事should have done本应该做某事而未做shouldn’t have done本不应该做某事而做了would have done本会某事而未做wouldn’t have done本不会做某事而做了need have done本需要做某事而未做needn’t have done本不必要做某事而做了3．—I don’t really like Janes.

仅仅是做一种观点上的表达。
He might have got stuck in traffic.He might have forgotten that we were meeting today.He might have overslept.3. couldn't have p.p.渴望、期望做某事, 但由于外部原因不可能做成, 即便是很想做。
是一种虚拟语气。

情态动词专项练习及答案详解
情态动词专项练习及答案详解一、单项选择情态动词1．—Tony _______ what I did annoying though he didn’t say anything.—So you think you will have to make an apology?A．could find B．should have foundC．might find D．must have found【答案】D【解析】【详解】考查情态动词+have done。
句意：—Tony一定觉得我做的事很烦人，尽管他什么也没说。
—所以你认为你得道歉吗?。
由“what I did”可知，此处是对过去事情有把握的推测，must have done“一定是做某事了”。
故选D项。
【点睛】情态动词+ have done结构：1.“must + have + 过去分词”表示对过去发生的事情或状态进行推测,语气比较坚定,通常只用于肯定句.如：It must have rained last night,for the ground is wet.2.“can / could + have + 过去分词”表示对过去某种情况的怀疑或不确定.can和could一般用于否定句和疑问句,could的语气较can弱.如：He can't have finished the work so soon.3.“may / might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推测,might的语气比may弱一点.这种结构主要用于肯定句和否定句,疑问句改用can或could.如：They may not have known it beforehand.4.“need + have + 过去分词”表示过去做了不必做或不需要做的事情,或过去做某事纯属多余.如：I needn't have bought so much wine—only five people came.5.“should / ought to + have + 过去分词”表示过去本该做某事但没做,其否定式表示过去不该做某事但做了,这种句式含有不满或责备之意,ought to的语气比should强一些.如：You ought to / should have studied harder.你本应该更努力学习的.（但没有）He oughtn't to / shouldn't have done that.他本来就不该做那件事.（可是做了）6.“would ＋ have ＋过去分词”表示对过去的某种情况进行猜测,或本来要做某事却因某种原因未做成,通常用来说明某一情况,但不像用should或ought to那样含有责备之意.如：I guess the poet would have been about twenty when she wrote her first poem.Another worker wouldn't have acted like that.分析句子可知，由“what I did”可知，此处是对过去事情有把握的推测，must have done“一定是做某事了”。

英语情态动词题20套(带答案)及解析
A．shallB．must
C．canD．should
【答案】D
【解析】
【详解】
考查情态动词。句意：我仍然难以想象这样聪明的孩子竟然犯这样愚蠢的错误。should作为情态动词，可以用来表示意外、惊喜或者在说话人看来是不可思议的，常常译为"竟会"、"居然"，这么聪明的孩子竟然犯这样愚蠢的错误。表示意外，shall表示允诺，命令等，must表示必须，can表示能力及可能性。所以答案选D。
【答案】B
【解析】
试题分析：考查情态动词用法。Shouldn’t have done本不应该做某事，实际上却做了（虚拟语气）；couldn’t have done不可能做某事（对过去情况的推测）；needn’t have done本不需要做某事，实际上却做了（虚拟语气）；句意：我的姐姐昨天下午在街上遇见了他，所以他不可能去听了你的演讲。故B正确。
3. shall用于第一、第三人称疑问句中，表示说话人征求对方的意见或向对方请示。如：Shall we begin our lesson? When shall he be able to leave the hospital?
4. shall用于第二、第三人称，表示说话人给对方命令、警告、允诺或威胁。如：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）

情态动词主要用来表示说话人的看法、态度等,但不能单独作谓语,只能和其他动词原形构成谓语。
1. can (could)1) 表示能力，could主要指过去时间。
例如：① Two eyes can see more than one. 两只眼比一只眼看得清。
② Could the girl read before she went to school? 这女孩上学前能识字吗？因为can不能和其他助动词连用，所以表示将来式时用will be able to例：You will be able to skate after you have practiced it two or three times.注意：Can表示一贯的能力，be able to表示客观能力和通过努力可以达到的能力I can’t swim. But I am sure I will be able to swim through more practicing.The fire spread through the hotel, but everyone was able to get out2) 表示允许。
例如：① Can I have a look at your new pen? 我可以看一看你的新钢笔吗？② 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。
3) 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。
例如：① Where can (could) they have gone to? 他们会去哪儿了呢？② How can you be so careless? 你怎么这么粗心？could 加完成式还用于肯定句时一般表过去可能完成而却未完成的动作。
You could have completed the task a little earlier.你本来能早点完成任务的。
（但事实上并没有提前完成任务）I could have passed my examination easily but I made too many stupid mistakes.我本可以轻易通过考试，但我犯了太多不该犯的错误。
如表具体做某一件事的能力时，则须用be able to .He was able to translate the article without a dictionary.他可以不用词典翻译那篇文章。
2．may (might)1) 表允许，might可以指过去时间，也可指现在时间，语气更委婉。
例如：① You may take whatever you like.你喜欢什么就拿什么。
② May (Might) I ask for a photo of your baby? 我可以要一张你宝宝的照片吗？2)在回答以may引起的问句时，多避免用这个词，而用其它方式，如Yes, please. / Certainly.等，以免显得太严峻或不客气。
/ Please don’t. / You’d better not. / No, you mustn’t.3)may /might 推测性用法可能He may be right. He may not come today (可能不) He may /might come tomorrow.注意: (1)只用于肯定和否定句中,不用于疑问句中。
(2) might 比may可能性更小He might get a job. He may get a job.(3) may not 可能不can not不可能He may not come . He can’t come4)表建议（可和as well 连用）You may（might）as well stay where you are. 你还是原地待着好。
（may as well 有“还是……的好”的含义）5)表祝愿May you be happy!6). might表过去的“可能”和“允许”多用于间接引语。
She said that he might take her dictionary. 她说他可以拿她的词典去用。
除在间接引语中外，might一般不表示过去的“可能”与“许可”。
表过去的“可能”可用could，表过去的“许可”可用were (was) allowed to。
7)might表现在的“可能”，其可能性要比may小。
Electric irons could be dangerous; they might give you a severe shock.8)may (might) + have +done 表示对过去发生行为的推测，含有“想必”、“也许是”的意思。
It may have been true. 这事也许是真的。
He might not have settled the question. 他可能尚未解决那个问题。
3. must1)表示义务。
意为“必须”（主观意志）。
例如：We must do everything step by step .我们必须按部就班地做一切事情。
Why must you always bother me? 为什么你偏要打扰我呢。
2)must be + 表语的结构，通常表示猜测，含有“一定”之意。
（只用在肯定句中）He must be an honest boy.他一定是个诚实的男孩This must be your room.这一定是你的房间。
或don’t have 3)must 的否定式有两个：当回答由must引起的问题时，否定答复要用needn’ｔto 表示“不必”、“无须”、“用不着”、“不一定”的意义。
当表示“不应该”、“不许可”、“禁止”时，就用must not。
Must I go tomorrow?明天我必须去吗？Yes, please. No , you needn’t.4)must +have +过去分词的结构，常用在肯定句中，表示对过去发生行为的推测，含有“一定”、“准是”的意思。
否定和疑问句用can。
She must have studied English before.她以前一定学过英语。
5) 区别：have to的含义与must是很接近的,只是have to 比较强调客观需要，must着重说明主观看法。
I must clean the room.（主观想法）I have to clean the room.（客观需要）另外，have to 能用于更多时态：We had to be there at ten .我们得在十点钟到那里。
We will have to reconsider the whole thing. have to 的否定式：don’t have to do 表示“不必做……”之意。
4.shall1) 表征询意见，用于第一、第三人称疑问句。
例如：① Shall I get you some tea? 我给你点茶好吗？② Shall the boy wait outside? 让那男孩在外面等吗？2)表说话人的意愿，有“命令、允诺、警告、决心”等意思，用于第二、第三人称陈述句。
例如：① You shall do as I say. 按我说的做。
（命令）② You shall have my answer tomorrow. 你明天可以得到我的答复。
（允诺）③ He shall be sorry for it one day, I tell you. 有一天他会后悔的，我告诉你。
（警告）④Nothing shall stop us from carrying out the plan. 什么也不能阻止我们执行这项计划。
（决心）5. should1)用于第一人称疑问句中询问对方的意愿，但语气较委婉温和，如：What should we do now? 我们现在该怎么办？2)表示应该、必须，常与must 换用。
例如：We should (must) master a foreign language at least.3）（表示不确定）万一。
例如：① If I should see him, I'll tell him. 万一我见到他，我就告诉他。
② If it should rain tomorrow, the sports meeting would be postponed. 万一明天下雨。
4)“should+be+表语”的结构，表示推测或惊奇。
例如：They should be back by now. 他们现在应该回来了吧。
I am sorry that she should be so careless. 我感到遗憾她竟会那样粗心。
5)“should+have+过去分词”的结构，表示过去该做而实际上尚未做的动作或行为；其否定则表示过去“早应该”、表示发生了不应该发生的行为。
其同义结构“ought to have +过去分词”，“本当”之意，语气较强。
例如：I should have thought of that. 这一点我是应当想到的。
（但没想到）They should not have left so soon.他们不应当走得这么早。
（但已走了）6) 在“It is natural (strange, natural, necessary, surprised, impossible, important ) that句型中，主语从句中的谓语动词要用should +动词原形”表示“理所当然”、“奇怪”、“必要”、“惊异”等的意思。
在lest（以免）、for fear (that) (以防)、in case（以备万一）等之后也要用should+动词原形;在advise, sugest, order, demand, request 等的从句中should+do”例如：It is necessary that he(should) be sent there at once.It is strange that he should say so. 他会说这样的话真是奇怪。
6.will和would的用法1）表示意志，决心或愿望。
例如：Surely we will support all the people in the world in their struggle for peace.He would not let me try it . 他不肯让我去试。
