(完整)情态动词专题讲解
(完整)情态动词专题讲解情态助动词专题训练概说助动词（auxiliary)主要有两类：基本助动词(primary auxiliary）和情态助动词（modal auxiliary）。
基本助动词有三个：do， have和be；情态助动词有十三个：may, might; can, could; will, would； shall， should； must, need， dare， used to, ought to。
上述两类助动词的共同特征是，在协助主动词构成限定动词词组时，具有作用词的功能：1）构成否定式:He didn’t go and neither did she.The meeting might not start until 5 o'clock。
2) 构成疑问式或附加疑问式：Must you leave right now?You have been learning French for 5 years, haven’t you?3) 构成修辞倒装:Nowhere can he obtain any information about his sister。
Hardly had he arrived when she started complaining.4）代替限定动词词组：A: Who can solve this crossword puzzle？B： Tom can.A: Shall I write to him?B： Yes， do.情态助动词的特征基本助动词与情态助动词最主要的区别之一是，基本助动词本身没有词义,而情态助动词则有自己的词义，能表示说话人对有关动作或状态的看法,或表示主观设想：What have you been doing since？（构成完成进行体,本身无词义）I am afraid I must be going. （一定要）You may have read some account of the matter. (或许已经）除此之外，情态助动词还有如下词法和句法特征：1）除ought和used以外，其他情态动词后面只能接不带to的不定式。

——好主意，这是母亲节的一个特殊的礼物。
A. can’t不能；B. mustn’t禁止；C. shouldn’t不应该；D. needn’t不必。
根据题意，表示不必给母亲买礼物。
故选D。
2．A解析：A【解析】【详解】句意：请你说大点声好吗？我不能很好地听到你说的话。
考查情态动词辨析。
can't不能，表示不能够；mustn't不许，表禁止；shouldn’t不应该，表劝诫；needn’t无需，表示没必要。
本句表示“不能够”，根据句意语境，可知BCD三项意思都与句意不合，故选A。
3．C解析：C【解析】【详解】句意：——你认为网上购物安全么？——我觉得是的。
淘宝上，消费者可以无理由退货，但是他们要承担运费。
考查情态动词辨析。
A. can’t; can不能，能；B. must; must必须，必须；C. can; have to可以，不得不；D. mustn’t; can禁止，能。
根据句意表示的是顾客能退货，是可以，第一空用can；但是不得不承担运费，非主观情愿用have to。
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：——那顶帽子是Bob的吗？——不，那不可能是他的。
他的是蓝色的。
考查情态动词表推测。
can’t 不可能，否定推测；mustn’t 禁止，不表推测；needn’t 不需要；may not 可能不是，表不确定的推测。
根据回答“No”和“His is blue.”可知这里说话者表达完全否定推测，故选A。
【点睛】在情态动词表推测时，很多同学会搞混can’t和mustn’t，认为他们都表示完全否定的推测，在做题时容易误选。
can’t 不可能，表示完全否定的推测，但是mustn’t 禁止，并不用于表推测。
6．B解析：B【解析】【详解】句意：——吉姆坐火车来吗？——我不确定，他可能开自己的车。
考查情态动词辨析。
A项，必须，一定，表示肯定推测；B项，也许，表示有可能；C项，需要；D项，应该。
根据回答部分I’m not sure.可知，此处并不确定吉姆是开车来还是乘坐火车来，所以此处是“可能”。
故选B。
【点睛】must意为“必须，应该”，可以表示主观上一定要做什么或者肯定推测。
例如：I must go home to look after my mum. This pair of shoes must be hers. may意为“可以，也许”，可以表示请求或者推测（无法断定）。
例如：May I come in？ It may be hers，but I’m not sure. need意为“需要”，既是情态动词也是行为动词。
例如：You needn’t finish your homework right now. You need to tell him the truth. should意为“应该”，表示责任或者义务。
例如：You should finish practising playing the piano at first.7．A解析：A【解析】【详解】句意：——我戒不掉烟，医生。
——为了你的健康，恐怕你必须戒掉。
