(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。
情态动词讲解及练习(含答案)
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。

情态动词【知识要点】:情态动词（Modal verbs）本身有一定的词义，表示语气的单词。
但是不能独立作谓语，只能和动词原形一起构成谓语。
情态动词用在行为动词前，表示说话人对这一动作或状态的看法或主观设想。
情态动词虽然数量不多，但用途广泛，主要有下列： can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) must not.情态动词无人称和数的变化，情态动词后面跟的动词须用原形，否定式构成是在情态动词后面加 "not"。
疑问形式是将情态动词提至主语前。
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。
【典型例题】:【专题一】:can和could的用法【例1】Can you lift this heavy box?(体力)【解析】表示能力(体力、知识、技能)【练习】1.Mary speak three languages.(知识)2. you skate?(技能)此时可用be able to代替。
Can只有一般现在时和一般过去式;而be able to 则有更多的时态。
I’ll not be able to come this afternoon.当表示“经过努力才得以做成功某事”时应用be able to,不能用Can。
【例2】-----Can I go now?----- Yes, you can. / No, you can’t.【解析】表示请求和允许。
此时可与may互换。
在疑问句中还可用could,might 代替,不是过去式,只是语气更委婉,不能用于肯定句和答语中。
【练习】---- I come to see you tomorrow?---- Yes, you .----No, you /I’m afraid not.【例3】Can this be true?【解析】表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。
【练习】This be done by him.How this be true?【专题二】may和might的用法：【例1】----M ight/ May I smoke in this room?---- No, you mus tn’t.【解析】表示请求和允许。
might比may语气更委婉,而不是过去式。
否定回答时可用can’t或mustn’t,表示“不可以,禁止”。
用May I...?征徇对方许可时比较正式和客气,而用Can I...?在口语中更常见。
【练习】---- I take this book out of the room?---- Yes, you . No, you【例2】May you succeed!【解析】用于祈使句,表示祝愿。
【例3】He may /might be very busy now.【解析】表示推测、可能性(不用于疑问句)。
might不是过去式,它所表示的可能性比may小。
【练习】1.Your mother not know the truth.2.He very busy now.他现在可能很忙。
【专题三】must和have to的用法：【例 1】The man be our teacher。
那个人一定是我们的老师。
【例 2】I study hard because of my dream .为了我的梦想我必须努力学习。
【例 3】1.You come in time.你必须准时过来【解析】：must表示必须、必要。
表示主观对事物的推测时，意为想必、一定，只用于肯定句中;表推测时，情态动词与动词原形(常为be动词)连用。
而have to强调客观需要。
【练习】:1.Her play is boring,I go now.2.Your mother be waiting for you now.3.I go home,because my father is ill.【例4】---Must we hand in our exercise books today?---Yes,you---No,you【解析】：在回答由must引出的问句时，如果是否定的，不能用mustn’t,而用needn’t,don’t have to.must是说话人的主观看法,而have to则强调客观需要。
【练习】:---Must he go to school now?---Yes,he---No,he .【专题四】should及其否定式用法【例 1】：I should help her because she is in trouble.【解析】：should表示应该、劝告、建议和命令。
