高三英语情态动词2
高考英语第二轮复习情态动词_教学资料

看高考试题,学情态动词情态动词主要用来表示说话人的情感、态度等,是中学英语语法的重点,也是高考的热点,是单项填空必考的一个知识点。
情态动词在近五年高考中主要考查四点:情态动词表示推测和可能性的用法;情态动词与虚拟语气;情态动词的表达“情感、态度、语气等”,情态动词表示“必要性”等方面的用法。
请看近五年有关情态动词与虚拟语气考点分布表:二、情态动词试题的突破方法:(1) 学生首先从整体上把握情态动词的语法和语义特征。
(2) 逐个学习,了解每个情态动词的用法特征,尤其要熟练掌握一些常用或常考情态动词的基本用法并认真区别具有相同功能的、意思相近的情态动词的用法。
(3) 收集并熟练掌握真实的口语材料和近几年高考有关情态动词的试题,在真实的语境中去体会、领悟、印证、掌握情态动词的用法特征和常见考点。
三、情态动词的解题技巧:(2) 认真思考所给选项中情态动词的基本特征和用法,并结合语境推敲答案。
(3) 要注意把握时间概念。
情态动词无论是表达“推测和可能性”,还是表达“虚拟”这一概念,只要是对过去已经发生的事情进行描述,一律用“情态动词+have done”这一结构;对现在或将来的事情进行描述,用“情态动词+动词或系动词原形”。
例如:(NMET山东,24)Thank you for all your hard work last week. I don’t think we ______ it without you.A. can manageB. could have managedC. could manageD. can have managed根据题干中所给出的时间last week可知我们已经做完了工作,已经完成,故排除A、C 两项,再结合could have done表示虚拟语气以及与前面的I don’t think…,故说话者想表达的意思是:离开了你,我们本不可能完成这项工作。
故答案为B项。
四、情态动词用法归类与高考试题分析:(一)表示推测的情态动词对现在或将来情况推测,用情态动词+do / be / be doing…;对过去的推测,用情态动词+have done / been…;表示肯定推测的情态动词按可能性大小依次为must, should / ought to, may, might, could;否定推测,常用can’t / couldn’t,译为“根本不可能”、“想必不会”,表示推测的语气非常肯定,may not, might not或could not译为“可能不”、“也许不”,表示推测的语气不很肯定。

How can it be that he was late for the meeting?布什先生做什么事情都很准时,他怎么可能开会迟到呢?—Let's visit Tom together, Stephen.—There's no need to do so. He can't be at home, because I saw him board the flight to Beijing this morning.——Stephen,咱们一起拜访汤姆吧.——没必要这样做.他一定不在家,因为今天早晨我看见他登上了飞往北京的航班.2.may/might用于肯定句中可以用来表示不十分肯定的推测,意为“有可能”;用于否定句中也可以表示推测,may not意为“可能不”,表示一种不太确定的语气.The traffic is heavy these days. I might arrive a bit late, so could you save me a place?这些天交通很繁忙,我可能会来晚一点,请你帮我保留个位置好吗?3.must表示推测时只能用于肯定句中,意为“一定,必定”,表示十分肯定的语气(在疑问句中或否定句中要用can/could).—It's the office! So you must know eating is not allowed here.—Oh, sorry.——这是办公室!所以你一定知道这里不许吃东西.——噢,对不起.4.should用来表示推测时意为“应该”,即含有“按道理来说应当如此”的意思.There shouldn't be any difficulty about passing the road test since you have practiced a lotin the driving school.因为你在驾校训练了这么多,通过路考应该没什么困难.八、“情态动词+have done”结构1.should/ought to+have done,表示“过去本应该做而(实际)没有做的事情”,含有责备或遗憾的语气,意为“本应该……”.其否定形式为“should not/ought not to have+done”,表示某种行为本不该发生但实际上发生了.I shouldn't have watched that movie—it'll give me horrible dreams.我本不应该看那部电影——它会令我做噩梦.You ought to have come to the party yesterday, but why didn't you come?昨天你本来应该参加聚会的,可是你为什么不来?2.must+have done,用于肯定句,表示“过去一定做过某事”,表示一种很有把握的推测.注意,对过去发生的情况的否定推测常用“can't/couldn't+have done”表示.—Ye Shiwen won two gold medals in London Olympic Games.—She must have gone through tough training.——叶诗文在伦敦奥运会获得了两枚金牌.——她肯定受到严格的训练.—Do you know where David is?

高考英语情态动词用法详解
高考英语情态动词用法详解,想要满分的看过来情态动词的区分情态动词可以广泛分为四大类。
第一类只能做情态动词,包括may、might、must等。
第二类既能做情态动词,又能做实义助词,包括need、dare、can等。
第三类既能做情态动词,又能做助动词,包括shall、should、will、would等。
第四类是指具有情态动词特征的短语,包括have to、used to、ought to等。
Can/could通常代表许可的意思,能够广泛用于肯定句、否定句和疑问句中,而且could的表达效果通常要更加委婉。
Cannot是指“禁止”,通常用于警告和告示。
May/might的意思与can/could相似,用法也没有明显区别,不过其与后者相比大多用于正式文体,通常含有尊敬之意,其中,might较may表达的效果更加委婉,但不是很常用。
Shall通常用于表示征求意见,常用于疑问句中。
而will/would同样是表示请求,其中would的表达效果更为客气委婉,且大多用于第二人称。
Must则是表示必须、必要。
情态动词的用法重点学习:will ( would), can (could), may (might)。
will 1.客观情形主语自己不能做决定,不要受客观情形支配。
如I will be 18 years old next month. 下个月我就要18岁了。
这里的will和将来时态连用表明是受时间客观规律支配的,不以主观意志来做主的。
因此可以和一个词组be going to do 区别开来。
be going to do 也是将要的意思,用法和will有很大区别。
当be going to do 的主语是人的时候,意思为“打算,计划”;只有当其主语是物的时候才可以和will等同表示马上要发生,但是依然不可以用于表示自然规律的情形。
It is going to rain soon.= It will rain soon. 马上就要下雨了。

(完整版)高考情态动词讲解
语法专题(三)情态动词考点归纳考点一:情态动词表示能力1.表现在的或一般的能力:表示现在的或一般的能力用can或be able to,can 比be able to 使用得更普遍。
can 侧重指有能力做某事;而be able to更强调通过努力、克服困难做成某事。
A computer can't think for itself ;it must be told what to do.He is a native speaker of English,so he can of course speak English quite well.2.表示将来的能力:表示将来能力用will be able to。
If you have a good sleep,you will be able to work out this problem.如果你睡个好觉,你就能做出这道题。
3.表示过去的能力:could 表示过去一般的能力,即不表示做或未做某事;而was (were) able to do则表示过去有能力并且成功地做了某事,相当于managed to do something/succeeded in doing somethin。
g考点二:情态动词表示推测(可能性)可能性可分为客观的(理论的)可能性和具体事情实际发生的可能性。
1.客观的(理论的)可能性指并不涉及具体某事是否会发生,此种用法常常可以说明人或事物的特征。
can 用于肯定句中表示客观的(理论的)可能性,can用于疑问及否定句中则表示实际发生的可能性。
The World Wide Web is sometimes jokingly called the World Wide Wait because it can be very slow.A left- luggage office is a place where bags can be left for a short time,especially in a railway station.2.表示具体事情实际发生的可能性:表示具体事情实际发生的可能性的这些词后接动词原形是对现在事情的推测,后接完成式则表示对过去事情的推测;其中can,may/might,should,ought to,must 有时还可接进行时表示对现在正在进行的事情的推测。
