Grammar Focus
表示可能、怀疑、允诺、愿望、义务、必要、猜测等的动词就是情态动词。情态动词可以表示说话人的语气或某种情态，也可以表示推测。英语中表示推测的情态动词主要有 must, can, could, may, might等。
定义
句式 情态动词 意义 用法
肯定句 must
may/might/could
否定句 can’t/couldn’t
may not/might not
疑问句 can/could
一定;肯定
表示有把握的肯定推测
可能
表示不太有把
握的肯定推测
不可能
表示有把握的
否定推测
表示不太有把 握的否定推测
可能
表示推测
可能不
用法
1. 情态动词不能表示正在发生或已经发生的事情，
只表示期待或估计某事的发生。 2. 情态动词ought和have,后面只能接带to的不定式。
语法特征
3. 情态动词没有人称、数的变化，即情态动词第三
人称单数不加-s。
4. 情态动词没有非谓语形式，即没有不定式、分词
等形式。
can可表示能力/允许/可能性/怀疑猜测，意为“可以，会，能”；can’t意为“不会，不能，不可以”，还有
“不可能”之意。could为can的过去式，用法与can类似，常用于过去时态中；could还可用于现在时态中表示委婉客气，相当于can；could也可表示惊讶怀疑，不相信。
can
eg: He couldn’t be a thief.
may
may表示允许、也许，意为“也许；可能；可以”，语气不太可能。对may的一般问句的回答：
肯定回答一般是：Yes, please./ Certainly./ Sure等
否定回答一般是： No, you can’t/mustn’t.
might是may的过去式，与may用法类似，语气比may弱，表示推测的可能性更小，常用于肯定句和否定句中，不用于疑问句中。
must
must表示必须要做的事，意为“必须，应该”。must一般问句的否定回答用needn’t或don’t have to，而不用mustn’t，mustn’t意为“不可以，不能”，表示禁止，不许可。
eg: — Must we hand in our exercise book today
— Yes, you must. ( No, you needn’t.)
must还可表示有把握的推测，意为“一定、肯定”。must的过去式还是must。在回答以must开头的一般疑问句时，否定式需用needn’t，表示“不必”的意思。
