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。
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.yo.can..No.yo.can’t.【解析】表示请求和允许。

我可能不得不见我的朋友。
考查情态动词。
can’t 不能；might可能，have to不得不；needn’t不需要。
根据句意空格处必须是肯定的。
可知，此处表示“我可能不得不见朋友。
”所以去不了派对，故用might have to，故选B。
2．D解析：D【解析】【详解】句意：——我不能戒烟，医生。
——为了你的健康，恐怕你得这么做。
考查情态动词辨析。
must必须，强调主观意愿；can能，表能力或许可；need需要，指有必要；have to必须，强调客观需要。
根据“For your health为了你的健康”，可知无论愿不愿意戒烟是健康所需，故选D。
3．C解析：C【解析】【详解】句意：乔的生日我给她买了一条漂亮的项链。
她可能会喜欢，但是我不确定。
考查情态动词表示推测。
can表示能、可以；may表示可能，might是其过去式；must表示一定、必须。
根据题干中but I'm not sure．可知可能性较小的推测，则可用may或者might，B项中may后有系动词be，原句中有动词like，则只能用might。
故选C。
4．A解析：A【解析】【详解】句意：—温迪现在在教室吗？—我不确定。
她可能不在那里，十分钟前我在图书馆见过她。
考查情态动词表推测。
may not可能不；must not一定不要；shall not将不会；would not 将要、会、就会，表示虚拟、假设、条件等。
根据回答句“I’m not sure”，可推测后句应该是说：她可能不在那里。
是对现在情况的推测，may not“可能不”。
故选A。
5．A解析：A【解析】【详解】句意：你不必担心你的功课。
下次小心点，你会取得好成绩的。
考查动词need用法辨析。
need用作情态动词时常和不带to的不定式一起作谓语，否定式是将not置于其后，并有其否定的缩写形式needn't，在疑问和否定句中不加助动词；可知BCD三项表达错误。
用作行为动词时，need是一个普通的及物动词，用在肯定、否定和疑问句中均可，接不定式时要带to。
本句need用作及物动词，根据句意结构，故选A。
6．B解析：B【详解】句意：——我能带些牛奶和饼干到阅览室吗？——不行，我们学校规定学生不许在那里食用食物。
考查情态动词的用法。
can’t不能；mustn’t禁止，不许；needn’t不必；may not可能不。
由“a rule”可知，“学校禁止或不许学生在阅览室食用食物”。
故选B。
7．A解析：A【解析】【详解】句意：——Tom，我们8点将会去购物，对么？——是的，但是我可能会晚一点，所以不要等我。
考查情态动词词义辨析。
A. may可能；B. should应该；C. mustn’t禁止。
根据句意可知是可能会晚到。
故选A。
8．B解析：B【解析】【详解】句意：——妈妈，我从快递公司收到了一个大箱子。
它是什么？——我不确定。
可能是你祖母送的礼物。
考查情态动词。
should应该；might可能；must必须； will将，会。
根据“I’m not sure”可知下文是没有把握的肯定推测。
根据题意，故选B。
9．C解析：C【解析】【详解】句意：--这栋楼是多么好呀！它用来做什么的？--它可能是一个旅馆，我不确定。
A. must be一定是；B. have to be 不得不；C. may be也许是；D. can be可能是。
根据But I'm not sure可知，这里表示的可能性小；can 表示推测的是用于否定句或疑问句，故选C。
