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。

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
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′

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!
