情态动词表推测用法总结(整理稿)
情态动词表推测用法总结 （一）情态动词表推测 能用于表推测的情态动词： 英语情态动词表推测的时态构成 （1）语气部分：（以下情态动词语气由强至弱） 肯定句：must、may、might（=could） 否定句：can’t（=couldn’t）、mayn’t、mightn’t 疑问句：can、could（语气更加委婉不确定） （2）时态部分： 一般现在或一般将来时间的推测：情态动词+be；情态动词+v. 对过去时间的推测：情态动词+have done 对正在进行的时态的推测：情态动词+be doing （二）表许可、请求 1、 can, could 2、may, might 3、must 4、shall 5、will, would 1. can, could 1) 用在疑问句中，表示一般的请求。两者不同在于：用could 要比用can更加委婉，特别是没有把握得到允许时。 Can I go with you? 我能和你一起去吗？Could I ask you something? 我能问你一个问题吗？ 2) 用在陈述句中，表示许可：You can leave when you finish your work. 做完事情后你才可以走。 2. may, might 1) may用在疑问句中，也表示一般的请求。同can相比，may比较正式，常常表示尊敬之意。并且，may在疑问句中常用于第一人称，很少有May you…/they…这样的句型。Might比较少用在疑问句中，它表示请求的时候常用陈述句。 May I make a suggestion? 我可以提个建议？ 2) 用在陈述句中，表示许可，此时与can, could相近。 You may have a rest before we set out again. 我们再次出发之前你可以先休息一下。 3. must 1) 表示说话人“不许”和“禁止”某人做某事，有很强的劝告语气。 Cars must not be parked here.此地不准停车。 2) Must的一般疑问句的回答有两种，表示肯定，用Yes, you must. 表示否定，用No, you needn’t. Must I post this letter tomorrow? 我明天必须得寄掉这封信吗？ Yes, you must. 是的，你必须明天寄掉。
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
情态动词表猜测的用法
情态动词表猜测的用法 情态动词must,can,could,should,may,might 等可以用在句中表示猜测。 1.“情态动词+动词原形”表示对现在或将来情况的猜测 I don’t know where she is. She may be in Wuhan. 2.“情态动词+进行式”表示对现在或将来正在进行的情况的猜测 At this moment, our teacher must be correcting our exam papers. 3.“情态动词+完成式”表示对过去情况的猜测 You must have been caught in the rain on your way home yesterday. 4.“情态动词+完成进行式”表示对过去正在进行的情况的猜测 Your mother must have been looking for you. 5.推测的否定形式用can’t/couldn’t，may not/might not表示
Mike can’t have found his car, for he came to work by bus this morning. 6.句子中含有表示猜测的情态动词时，其反 意疑问句的构成不能再用原句中的情态动词，而应根据原句在去掉情态动词的情况下的主谓关系来确定其反问形式。 ①The man in the white clothes must be a doctor, isn’t he? ②She must have seen the film before, hasn’t she? ③He must have an uncle abroad, doesn’t he? ④You must have met Uncle Wang in the shop yesterday, didn’t you? 7.在表示“猜测”方面的区别 情态动词must,can,could,should,may,might 都可以用于表示“猜测”（注意：could, might 表示推测时不表示时态, 其推测的程度不如can, may）。实际上，“猜测”与“可能性”在逻辑上是有必然联系的。如果认为没有某种可能性，人们就不会作出某些猜测。因此，请注意六个情态动词之间的区别与它们各
高中英语情态动词讲解与练习(含答案)
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。 I'm sorry I can't help you. 对不起，我帮不上你。 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 to 和used to看做是固定词组的话，那么，所有情态动词无一例外地只能接不带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. 两只眼比一只眼看得清。 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℃。 t) have enough money for a new car. 他不可能有足够的钱买新车。 He can′ t (couldn′ re walking around in the wood. You could start a fire. You mustn′ t smoke while you′
情态动词表推测用法总结及专项练习
情态动词表推测用法总结及专项练习 1.can / could用于表推测的用法 (1) 从使用句型上看，can 通常只用于否定句或疑问句，一般不用于肯定句，而could 可用于肯定句、否定句和疑问句。两者没有时间上的差别，只是could 比can 更委婉，更不确定。如：It can’t [couldn’t] be true. 那不可能是真的。 What can [could] they be doing? 他们会在干什么呢? We could go there this summer. 今年夏天我们可能要去那儿。 注：can 有时也用于肯定句中表示推测，主要用于表示理论上的可能性(即从理论上看是可能的，但实际未必会发生)，或表示“有时”之意。如： Even experienced teachers can make mistakes. 即使是有经验的教师也可能出错。 She can be very unpleasant. 她有时很令人讨厌。 (2) 从时间关系看，对现在或将来情况作推测，后接动词原形；对正在进行的情况作推测，后接be doing 结构；对过去情况作推测，后接动词完成式。如： He could have gone home. 他可能已经回家了。 He can’t [couldn’t] have understood. 他不可能理解了。
Why does he know this? Can [Could] someone have told him about it? 他怎么知道? 会是哪个人告诉他了吗? (3) “could+完成式”除表示对过去的推测外，还有以下重要用法： ①表示过去没有实现的可能性，常译为“本来可以”。如： I could have lent you the money．Why didn’t you ask me? 我本来可以借这笔钱给你的。你为什么不向我提出? ②用来委婉地责备某人过去应该做某事而没有去做，常译为“本来应该”。如： You could have helped him. 你本来应该帮助他的。 ③表示“差点儿就要”。如： I could have died laughing. 我差点儿笑死了。 2. may / might用于表推测的用法 表示推测，两者都可用，只是might 比may 语气更不确定，表示的可能性更小。 (1) 在句型使用方面：两者均可用于肯定句和否定句，但用于疑问句时，may通常不用于句首，但可用于疑问句的句中（如特殊疑问句等），而might尽管可以用于疑问句的句首，但不算普通，通常会改用其他句式（如用could等）。如： He may [might] know the answer. 他可能知道答案。
最新情态动词表推测的讲解及练习题
九年级英语表推测语气的讲解与练习 表推测时，英语中只使用must,may,might,may not和can't。这五个表达的语气依次递减： must:一定（语气肯定） may：也许（不很肯定） might：或许（比may语气更弱） may not：也许不（表否定） can't：一定不（must的反义） 推测现在的事情用must,may,might,may not和can't+do或be e.g.She must be at home now. The boy may play now. 推测过去的事情用must,may,might,may not和can't+have done e.g.She might have been ill yesterday. He must have hold the party. 情态动词must, can, could, may, might表推测的用法 情态动词中的must, can, could, may, might都表推测。其中must的可能性最大，can / could次之，may / might最小。具体用法如下： 1.must的用法 （1）表示推测“可能性”时，意思是“一定、准是”，语气较肯定，较有把握。He must be American. = It is certain that he is American. 他准是个美国人。 （2）must表推测只能用于肯定句。如果要表示“一定不、肯定不”的意思时，应用can’t,如询问某种可能时，应用can。 He must know my address. 他肯定知道我的地址。（一定） He can’t know my address. 他肯定不知道我的地址。（一定不） Can he know my address? 他知道我的地址吗？（询问可能性） （3）must表示推测时，可以推测现在/正在发生的动作/过去发生的动作。 He must have a car now. （现在）他一定有辆小汽车。 He must be doing his exercises in the classroom.（正在进行）他一定在教室里做练习。 He must have finished the work.（过去发生）他一定已完成了工作。 注：must表示推测时很少用于将来的情况。一般不用He must come tomorrow.可用It`s certain / I’m sure that he will come tomorrow. （4）在反意疑问句中，当附属部分含有表示推测意义的must时，疑问部分的助动词应与must后面的动词在非推测情况下的用法保持一致。 He must be a worker, isn’t he? （现在）他准是个工人，是吗？ It must have rained last night, didn’t it? （过去）昨晚一定下雨了，是不是？

情态动词表推测的用法
情态动词表推测的用法 一、must表示推测的用法 must表示推测时，只用于肯定句，表示很大的可能性，意为“一定，准是，必然会”。其否定形式是can’t/couldn’t (不可能)。例如： 1. You haven’t eaten anything since this morning; you must be hungry. 2. That can’t be Mary —she’s in hospital. 二、can/could表示推测的用法 1. can表示推测时，多用于肯定句和疑问句。当用于肯定句时，指“有时可能会”，是理论上的可能，其时间意义宽泛不具体。例如： Even experienced teachers can make mistakes. 2. could表示推测时，既可以用于肯定句，又可以用于疑问句。例如： My book has disappeared. Who could have taken it? 3. can’t/couldn’t表示推测时，用于否定句，是语气最强的否定推测，意为“不可能，一定不(是)”。例如： He can’t/couldn’t have see n her there. 【即学即练】 一、用表示推测的情态动词must, could, , can的适当形式填空。 1. — Hi, Tom. Any idea where Jane is? — She be in the classroom. I saw her there just now. 2. — I hear they went skiing in the mountains last winter. — It be true because there was little snow there. 3. Accidents happen on such rainy days. 二、翻译下列句子，注意情态动词的推测用法和情态动词后动词的形式。 —那个人一定是布朗先生。—不可能是他，他去纽约了。 【反义疑问句】又叫附加疑问句。它表示提问人的看法，没有把握，需要对方证实。反义疑问句由两部分组成：前一部分是一个陈述句，后一部分是一个简短的疑问句，两部分的人称时态应保持一致。如：She was ill yesterday, wasn’t she? They don’t work hard, do they?
