小学英语情态动词知识点与练习题
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】----Might/ May I smoke in this room?
---- No, you m ustn’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。
【练习】:
1.You go to class right away.
2.I open the window?
【专题四】need的用法

【解析】need 作情态动词用时, 常用于疑问句、否定句。在肯定句中一般用must, have to, ought to, should代替
【练习】
---- Need I finish the work today?
---- Yes, you / No, you
【专题五】should的用法
【例1】I should help her because she is in trouble.
【解析】should表示应该

小学英语情态动词知识点及练习
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。
