情态动词的用法 完整版
情态动词定义:情态动词是一种本身有一定的词义,但要与动词原形一起使用,给谓语动词增添情态色彩,表示说话人对有关行为或事物的态度和看法,认为其可能、应该或必要等。
情态动词后面加动词原形。
分类:情态动词有四类:①只做情态动词:must,can(could),may(might),ought to②可做情态动词又可做实义动词:need,dare③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) to,used to位置:情态动词在句中放在谓语动词之前, 谓语动词前若有助动词,则在助动词之前,疑问句中, 情态动词则在主语之前。
I can see you. Come here.我能看见你,过来吧。
He must have been away.他一定走了。
What can I do for you?我能帮你吗?How dare you treat us like that!你怎能那样对待我们!特点: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。
情态动词没有非谓语形式,即没有不定式,分词,等形式。
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。

句意:如果我们对超载车辆问题给予足够的重视,就可以避免无锡立交桥垮塌的悲剧。
本句为“情态动词+have done”结构,结合句意表示“本来可以;本来能够”应用could have done结构,且主语与谓语动词avoid构成被动关系,故应用be done形式。
故选D。
【点睛】情态动词+have done的结构和用法有以下几种:一、must have done sth.“一定做了某事”。
表示对过去事情的较有把握的推测,这时只能用在肯定句中,“肯定/必须已经干过……”,在否定句和疑问句中用can’t或could n’t或can/ could,例如:1.From what you said, she must have told you all about it. 从你的话看,她一定告诉了你所有的事情。
二、can/could have done sth.本来能够做某事,而实际上未做;1.But we could have done it all so much better. 但是,我们本可以把这一切做得更好。
三、can't/couldn't have done sth.不可能做过某事;1. We could't have done it without you.没有你我们办不成这事。
四、ought to/should have done sth.过去本应该做某事而实际上并没有做。

(完整版)小学英语情态动词知识点及练习
神情动词【知识要点】 :神情动词( Modal verbs )自己有必然的词义,表示语气的单词。
但是不能够独立作谓语,只能和动词原形一起构成谓语。
神情动词用行家为动词前,表示说话人对这一动作或状态的看法或主观设想。
神情动词诚然数量不多,但用途广泛,主要有以下:can (could), may (might), must, need, ought to,dare (dared), shall (should), will (would) must not.神情动词无人称和数的变化,神情动词后边跟的动词须用原形,否定式构成是在神情动词后边加 "not" 。
疑问形式是将神情动词提至主语前。
个别神情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,宛转的语气,时态性不强,可用于过去,现在或将来。
神情动词属非及物动词,故没有被动语态。
【典型例题】:【专题一】 : can 和 could 的用法【例 1】 Can you lift this heavy box? ( 体力 )【剖析】表示能力 ( 体力、知识、技术 )【练习】1. Mary speak three languages.( 知识 )2.you skate?( 技术 )此时可用 be able to 代替。
Can 只有一般现在时和一般过去式则有更多的时态。
; 而be able toI ’ ll not be able to come this afternoon.be able to,不能够用Can。
当表示“经过努力才得以做成功某事”时应用【例 2】-----Can I go now?-----Yes, you can. / No, you can’t.【剖析】表示恳求和赞同。
此时可与 may互换。
在疑问句中还可用 could,might 代替 , 不是过去式 , 可是语气更宛转 , 不能够用于必然句和答语中。
【练习】----I come to see you tomorrow?---- Yes, you.---- No, you/I ’m afraid not.【例 3】 Can this be true?【剖析】表示推断 ( 惊讶、思疑、不相信的态度 ), 用于疑问句、否定句和惋惜句中。
