ⅰ. 情態(tài)動(dòng)詞
情態(tài)動(dòng)詞有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。 情態(tài)動(dòng)詞無人稱和數(shù)的變化；不能單獨(dú)使用，必須與其后的動(dòng)詞原形構(gòu)成謂語(yǔ)。
1. can, could
1) 表示能力（體力、知識(shí)、技能）。 例如：
can you lift this heavy box?（體力）
mary can speak three languages.（知識(shí)）
can you skate?（技能）
此時(shí)可用be able to代替。can只有一般現(xiàn)在時(shí)和一般過去式；而be able to
則有更多的時(shí)態(tài)。例如：
i’ll not be able to come this afternoon. （一般將來時(shí)）
當(dāng)表示“經(jīng)過努力才得以做成功某事”時(shí)應(yīng)用be able to，不能用can。如：
he was able to go to the party yesterday evening in spite of the heavy rain.
2) 表示請(qǐng)求和允許。 例如：
-----can i go now?
-----yes, you can. / no, you can’t.
此時(shí)可與may互換。在疑問句中還可用could, might代替，但could, might 并不表示過去式，只是語(yǔ)氣更委婉。它們不能用于肯定句和答語(yǔ)中。 例如：
---- could i come to see you tomorrow?
---- yes, you can. (no, i’m afraid not.)
3) 表示客觀可能性（客觀原因形成的能力）。例如：
they’ve changed the timetable, so we can go by bus instead.
this hall can hold 500 people at least.
4) 表示推測(cè)（驚訝、懷疑、不相信的態(tài)度），用于疑問句、否定句和感嘆句中。
can this be true?
this can’t be done by him.
how can this be true?
2. may, might
1) 表示請(qǐng)求和允許。might比 may語(yǔ)氣更委婉，而不是過去式。否定回答時(shí)可用can’t 或mustn’t，表示“不可以，禁止”。 例如：
----might/ may i smoke in this room?
---- no, you mustn’t.
---- may/might i take this book out of the room?
