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... yo.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。

【例2】-----Can I go now?----.Yes.yo.can..No.yo.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.yo.....----No.yo..../I’.afrai.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。

初二下册 unit 3 情态动词 练习测试题 带参考答案
概念引入情态动词有具体的词义，但也同助动词一样，需要与其他词语一起构成句子的谓语，另外情态动词没有人称和数的变化，情态动词后必须跟动词原形。
用法讲解I、常见情态动词的用法一、can的用法：Couldyoudomeafavour?你能帮我个忙吗？—CouldIuseyourpen?我能用一下你的钢笔吗?—Yes,youcan.可以。
三、may的用法：(1)表示请求、许可，比can正式。
例如：MayIborrowyourbike?我可以借你的自行车吗？Youmaygohomenow.现在你可以回家了。
(2)表示推测，谈论可能性，意为“可能，或许”，一般用于肯定句中。
例如：Itmayraintomorrow.明天可能会下雨。
Shemaybeathome.她可能在家呢.(3)may的过去式为might，表示推测时，可能性低于may。
?例如：Heisawayfromschool.Hemightbesick.他离开学校了，可能是他生病了。
(4)表示希望、祈求、祝愿，常可译为“祝愿”。
通常是用may+主+动词。
例如：Mayyouhaveagoodtime.祝你过得愉快。
Mayyoubehappy!祝你幸福！五、need的用法：(1)need表示需要、必须，主要用于否定句和疑问句中，其否定形式为needn’t，意为“没有必要，不必”。
用need提问时，肯定回答为must，否定回答为needn’t或don’thaveto。
?例如：—NeedIstayhereanylonger?我还有必要留在这儿吗？—Yes,youmust.是的。
—No,youneedn’t/don’thaveto.不，你不必。
(2)need还可以作实义动词，此时有人称、数和时态的变化，如果是人作主语，后边多接动词不定式。
例如：Ineedtodoitrightnow.我需要马上做这件事。
Heneedstolearnmoreaboutthegirl.他需要多了解那个女孩。

一般不用He must come tomorrow.可用It`s certain / I`m sure that he will come tomorrow.（4）在反意疑问句中，当附属部分含有表示推测意义的must时，疑问部分的助动词应与must后面的动词在非推测情况下的用法保持一致。
He must be a worker, isn`t he? （现在）他准时个工人，是吗？It must have rained last night, didn`t it? （过去）昨晚一定下雨了，是不是？You must have learned English for many years, haven`t you? （完成时）你一定学了好多年英语，是吗？2. can / could的用法（1）can表示推测“可能性”时，往往用于否定句或疑问句。
