情态动词用于推测的情况,指对某事情的发生与否进行推测,后面接不同的内容表示对不同的时态所发生的事情与否进行推测。

1.情态动词+动词原形对应于一般现在时,表示对经常发生的,有规律的事情的推测

2.情态动词+be+v-ing 对应于现在进行时,表示对正在发生的事情的推测

对某事情的发生与否进行推测常用的情态动词:

2.对事情的肯定的,不是完全有把握的推测,依照对其发生概率的肯定程度的强弱大小,依次用could, may, might,其肯定程度逐渐减弱,意思为“可能”。

3.对事情的否定的,完全有把握的推

测用can't,表示“一定不,不可能”

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

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。

(完整word版)初中情态动词练习题及答案

(完整word版)初中情态动词练习题及答案 一、单项选择情态动词 1.—_______ you disturb me now? I’m busy preparing a report. — Terribly sorry, but I have something urgent to tell you. A.Need B.Should C.Might D.Must 【答案】D 【解析】 【详解】 考查情态动词特殊用法。句意:—你非要现在打扰我吗?我正在准备一份报告。—真对不起,但是我怕有紧急事情告诉你。A. Need需要;B. Should 应该;C. Might也许;D. Must 必须;一定;偏偏,非得;根据语境可知must表示“偏偏,非得”符合上下文语境,用来指责对方。故D项正确。 2.It is really cold and the ground is wet; it ________ have rained last night. A.might B.must C.can D.should 【答案】B 【解析】 【详解】 考查情态动词辨析。句意:天气很冷而且地面是湿的,昨晚一定下了雨。根据上文the ground is wet可知,“昨晚下了雨”是肯定的,故用must have done“必定做了……”表示对过 去十分有把握的推测,故选B。 【点睛】 must have done用法辨析 must have done:表示对过去的肯定的逻辑推测,推定某件事情、动作或状态可能在过去发生过(存在过)。 He must have been a doctor, for he knows medicine so well. 他过去肯定是一位医生,他对医学如此了解。 Somebody must have stolen the ring. 肯定有人偷了这枚戒指. [该句所推断的偷窃动作发生在过去.] The temperature must have dropped to below zero last night, because the water is frozen all over.昨夜的温度肯定降到零度以下,因为水都冻住了。 如果“must + have + 过去分词”句型与by now连用,还可以表示对现在完成的动作和状态的肯定推测,但实质上还是指所推测的过去的动作。例如: They started early this morning; they must have arrived by now. 他们今晨很早就出发了,现在肯定已经到了。 中国学生的常见病句是:They...; they certainly have arrived.病句的句义是“他们当然已经到 达了。”(这不是对过去的肯定推测,而是断定动作已经完成。)

How can you be so careless! This cannot be done by him. 2. may和might的用法 ①表示许可。如: You may drive the car. —May/Might I use your pen? —No,you mustn't. ②用于祈使句中表示祝愿。如: May you succeed! ③表示推测、可能(疑问句不能用于此意)。表推测的might并不是指过去时间,而表示比may把握性略小些。如: He may be very busy now. ④用于表示目的或让步状语从句中。如: No matter what difficulties you may come across,you shouldn't give up. 3. will和would的用法 ①用于各种人称,表示“意志”“意愿”“决心”等。如: I told her to stop crying,but she just would not listen. ②用于第二人称的疑问句,表示说话人向对方提出请求。用would比用will语气更客气。如: Will/Would you please keep the door open? ③表示真理或习惯,意为“惯于,总是”。如: She will listen to music alone in her room for hours. He would get up early when he lived in the country. 4. should的用法 ①表示现在或将来的责任或义务,意为“应该,应当”,这时它可以和 ought to,be supposed to 互换使用。如: You should(=are supposed to ) complete your test in time. ②表示有较大可能实现的猜测、推论,通常意为“可能;总该……吧”,相当于 be expected to。如: They should be home by now,I think. ③用于第一人称时可以表示说话人的一种谦逊、客气、委婉的语气。如: I should think it would be better to try it again. ④用在条件状语从句中,表示语气较强的假设,意为“万一”,这时也可将should置于从句之首,即将should放在主语前面,而省略从属连词if,主句谓语却不一定用虚拟语气。如: Should I (=If I should) be free tomorrow I will come. ⑤用来表示意外、惊喜或者在说话人看来是不可思议的。尤其在以 why,who,how 等开头的修辞疑问句或某些感叹句中常常意为“竟会,居然”。如: A gentleman like him should be rude to a lady! ⑥用于虚拟语气句中(略)。 5. ought to的用法 表示应该、推测,相当于should。如: You ought to take care of him. 6. shall的用法

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?
