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。

情态动词讲解及练习(含答案)一、单项选择情态动词1．—You rang me up at about 10:00 last night, didn't you?—No, I didn't phone you. It someone else.A．must have been B．could be C．must be D．could have been 【答案】A【解析】【详解】考查情态动词+have done。

句意：“昨晚10点左右你给我打了电话，是吗？”“不，我没给你打电话。

一定是别人干的。

” must have done 是对过去发生的动作最有把握的猜测，意思是“一定”，结合语境可知，我没有打电话给你，因此猜测一定有别人给你打了电话。

故选A 项。

2．—I don’t really like Janes. Why did you invite him?—Don’t worry. He come. He said he was’t certain what his plans were.A．must not B．need not C．would not D．might not【答案】D【解析】考察情态动词，题干中的he wasn’t certain说明他可能不来，可能来，因此使用不完全否定，might not。

3．Mr. Baker, some students want to see you. ______ they wait here or outside?A．May B．Should C．Shall D．Will【答案】C【解析】【详解】考查Shall的用法。

句意：贝克先生，有些学生想见你。

他们是在这里等还是在外面等?Shall用于第一、第三人称疑问句中，表示说话人征求对方的意见或向对方请示。

故选C。

【点睛】Shall的用法Shall作为助动词，一般用于第一人称Ⅰ和We，表示一个将来的动作，构成将来时态。

小学常考情态动词（can,must,should,might）及习题情态动词:情态动词本身具有一定的词义，表示说话人的某种语气或感情，但不能单独作谓语，通常要和行为动词一起构成谓语。

情态动词没有人称和数的变化，适用于所有人称，其后要接动词原形。

一、情态动词can的用法：1、其中情态动词can表能力时意为“能够做某事”，后接动词原形；否定形式为can't或cannot；can的过去式为could。

例：1.Tony can play basketball, but he can't play the piano.Tony会打篮球，但他不会弹钢琴。

2.Can Lily speak Chinese? —Lily会说中文吗？-Yes, she can. —是的，她会。

3.What can you do, Kate? —Kate，你会做什么？-I can play the violin. —我会拉小提琴。

2、其中情态动词can表许可或请求别人的许可时，意为“可以”，后接动词原形，相当于may，但may多用于正式、庄重的场合；can的否定形式为can't 或cannot。

例：You can go now if you like. 如果你想走，现在就可以走了。

-Mark, can I use your pen? —Mark，我能用下你的钢笔吗？-Of course. —当然了。

二、情态动词must表示“必须，应该，一定要”。

●∙主语是第一人称I或we时，表示说话人认为有必要或者有义务做某事；主语是第二、第三人称you、they、he、she等时，表示说话人要求或命令别人做某事。

●∙must的否定形式为must not，缩写为mustn't，意为“不许；严禁”。

●∙must引导的一般疑问句，肯定回答用must，否定回答用needn't或don'thave to，意为“不必”。

小学情态动词入门详解与练习兴趣是最好的老师。

不要求成绩的让孩子看、听英语，对孩子来说绝对是一种享受。

小偏整理了小学情态动词入门详解与练习，欢迎参考借鉴。

小学情态动词入门详解与练习一、定义情态动词表示说话人对某一动作或状态的态度，表示“可能”，“可以”，“需要”，“必须”，“应当”等意思。

情态动词没有人称和数的变化，后面的动词要用原形。

二、情态动词的种类：情态动词词义否定形式词义can能够，会can’t不能，不会could能够，会couldn’t不能，不会may可以//must必须mustn’t不允许，不能shall将，要//should应该shouldn’t不应该need需要needn’t不必would将会，愿wouldn’t不会，不愿三、情态动词的常见用法：1.can和could的用法(1)can/could 表示“能力;许可;可能性”等。

could 为 can 的过去式。

如：Can I use your book?我可以用你的书吗?(2)can 用在疑问句中，表示征求意见、请求许可，答语仍用can; could 用在疑问句中，比can 更委婉、客气，是一种礼貌的说法，并不表示过去时态，答语用can，而不能用could。

Eg: -Could you tell me the way to the park?你能告诉我去公园的路吗?-Sorry. I can't. I'm new here。

不好意思，我不知道。

我是新来的。

[注意]①can 和could 只能用于现在时和过去时两种时态。

②另外， can't 可表示否定推测。

2.may和might的用法may/might 意为“可以”，表示同意、许可或请求对方许可，也可表示祝愿。

might 是may 的过去式，有两种用法：一种表示过去式;一种表示虚拟语气，使语气更加委婉、客气，或表示可能性更小。

以may开头的一般疑问句，其否定回答用mustn't。
