Grammar Focus
情态动词表推测
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。英语中表示推测的情态动词主要有 must, can, could, may, might等。
Introduction
Grammar
Characteristic
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。
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。
Grammar
can
情态动词
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。
Grammar
情态动词
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。
Grammar
情态动词
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。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。
eg: — Must we hand in our exercise book today
— Yes, you must. ( No, you needn’t.)
