初中英语语法之表推测情态动词用法和练习

初中英语语法之表推测情态动词用法和练习英语中有不少情态动词都可以表示推测,其语气有强有弱,表示的可能性有大有小,现将它们的用法归纳如下:1. 接近100%的可能这当然只有must才具有这么高的可能性,它的意思是“一定”“肯定”,所作出的推测几乎接近事实。

如:That hat must be Tom’s. 那帽子一定是汤姆的。

He must be coming by bus. 他一定是乘公共汽车来。

2. 很有可能表示可能性较大的情态动词主要有may, should, ought to,它们大致相当于汉语的“可能”“应该”“按理会”。

如:She should [ought to] be here soon. 她应该很快就到。

We may be buying a new house. 我们可能要买一座新房子。

3. 一般性的可能在所有表示推测的情态动词中,might和could所表示的可能性最小,由于它们的语气较委婉,较不确定,所以往往相当于汉语的“可能”“也许”“说不定”等。

如:He might be waiting for you. 他可能在等你。

She might not like the idea. 她或许会不赞成这个想法。

We could all be millionaires one day. 我们有一天可能都成为百万富翁。

4. 理论上的可能性表示理论上的可能通常是用can,且可以用于肯定句中。

如:Food poisoning can cause death. 食物中毒可导致死亡。

This kind of thing can happen every now and then. 这种事情是随时可能发生的。

New England can be very hot in September. 新英格兰有时9月份很热。

所谓理论上的可能性,就是指仅从理论上去考虑其可能性,至于实际情况如何,则不作考虑,比如说“食物中毒可导致死亡”,这只是理论上的一种推断,至于某人某次食物中毒了,他是否会死亡,则不在考虑之列,所以说,这种推测是非常“宏观”的!5. 表示对过去情况作推测如果表示对已经发生的情况作推测,不能用“情态动词+动词原形”,也不能用“情态动词的过去式+动词原形”,而是要使用“情态动词+动词完成式”。

初三英语情态动词表推测单选题50题

初三英语情态动词表推测单选题50题1.She have a lot of friends. She is always surrounded by people.A.mayB.mightC.canD.must答案:A。

本题主要考查may 和might 表推测的用法。

may 表示有可能,可能性比might 稍大。

在这个语境中,她总是被人围绕,有较大可能有很多朋友,所以用may。

can 表示能力或可能性,但这里不是强调能力,must 表示肯定,语气太强,不符合语境。

2.There be a test tomorrow. The teacher didn't say anything definite.A.mayB.mightC.shouldD.will答案:B。

这里表示对明天是否有考试的不确定推测,might 的可能性比may 更小。

should 表示应该,will 表示将来会,都不符合推测的语境。

3.He have forgotten his homework. He usually is very responsible.A.mayB.mightC.can答案:A。

根据后面说他通常很负责,所以这里是有一定可能性忘记了作业,用may。

might 可能性更小,can 表示能力或可能性,但这里不是强调能力,must 表示肯定,不符合语境。

'tD. ’t情态动词表推测用法总结及专项练习1 / 用于表推测的用法(1) 从使用句型上看,通常只用于否定句或疑问句,一般不用于肯定句,而可用于肯定句、否定句和疑问句。

两者没有时间上的差别,只是比更委婉,更不确定。

如:’t [’t] . 那不可能是真的。

[] ? 他们会在干什么呢?. 今年夏天我们可能要去那儿。

注: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:. 即使是有经验的教师也可能出错。

. 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,后接结构;对过去情况作推测,后接动词完成式。

如:. 他可能已经回家了。

’t [’t] . 他不可能理解了。

? [] ? 他怎么知道? 会是哪个人告诉他了吗?(3) “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 .’t ? 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:. 你本来应该帮助他的。

③表示“差点儿就要”。

如:I . 我差点儿笑死了。

2. / 用于表推测的用法表示推测,两者都可用,只是比语气更不确定,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,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(如用等)。

如:[] . 他可能知道答案。

[] . 他可能不会相信你。

[] ? 那么她会是哪一位呢?(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,后接结构;对过去情况作推测,后接动词完成式。

如:[] . 他也许会告诉他妻子。

[] a . 他可能在写信。

[] . 她可能在报上已读到过此事。

(3)“完成式”除表示对过去的推测外,还有以下重要用法:①表示过去某事可能发生而实际上却并没发生。

如:. I . 那真的是太危险了,我差点没命了。

A .很多人本来可以获救的却死了。

②表示委婉的批评或责备。

如:. 你的进步本来可更大一些的。

. 你至少可以回我一封信嘛。

3. 表示推测的用法表示很有把握的推测,其意为“一定会”“肯定会”,只用于肯定句,一般不用于否定句或疑问句。

表示对现在或未来的情况作推测,后接动词原形;表示对过去情况的推测,接动词完成式。

如:I ! 我一定是世界上最幸福的女人了。

, . 不,他一定在撒谎. 他一定误会了我的意思。

4. 的用法只用于谈论过去情况,主要有两个用法:一是用于推测过去已经发生的情况,二是用于指本该发生而实际上未发生的情况。

如: . 你早就应该告诉我。

. 此时他本该到了。

! . 瞧都什么时候了! 十分钟前我们就该到戏院了。

5. 的用法结构主要用于否定句或疑问句,一般不用于肯定句。

用于否定句时,表示本来不必做某事,但实际上却做了;用于疑问句时,用于询问某一过去动作的必要性。

如:’t . 你当时实在不必那么匆忙。

’t — a . 她本不必亲自来——写封信来就足够了。

? 你当时真须要付那么多钱吗?? 他们那时非得把农场卖掉不可吗?历届中表推测的情态动词的用法情态动词是中学英语学习中的一个重点和难点,也是高考的重点考察内容之一。
