2. 情态动词种类:
can
①表示能力,“能够;可以”。

②表示许可,请求“可以”
e.g. Can you…
③ can’t be 用于否定推测(100%否定)
e.g. It can’t be true!
could
①表示能力“能,会”,是can的过去式。
e.g. My father could swim when he was ten years old.
② Could在疑问句中,表示委婉的语气,此时could没有过去式的意思。表请求,但是回答时不可用could。
e.g. —Could you help me
—Yes, you can./No, you can’t.
must
① “必须”
e.g. I must find my phone.
②否定mustn’t“禁止,不准”

it just now.
④疑问句:Must I…
肯:Yes, 主语+must.
否:No, 主语+needn’t/don’t have to/doesn’t have to.
(不能用mustn’t)
e.g.—Must I clean my room now
—Yes, you must.

must & have to区别:
都表示“必须”
1.must指人的主观看法。
We must work hard.
2.have to表客观需要 “不得不”,通常带有不愿意的意味。 e.g. My bike was broken. I have to walk to school today.
3.must 没有人称和数的变化,但have to 有人称和数的变化。

He has to stay at home.
may
①表示推测,“可能,也许”,常用于肯定句。
e.g. He may like the black pencil box.
②表示请求、许可,“可以,允许”,may比can正式。
这里的might比may 语气更委婉,而不表示过去式。
e.g. May/Might I come in
③ May/Might I … 一般疑问句答语
肯定回答:Yes, you may./Yes, please./Certainly/OK/Sure
否定回答:No, you can’t(不能)/mustn’t. (不准,禁止)/Please don’t.
其他的情态动词:
should “应该”表劝告、建议等
shall “应该,将要”+I/we do sth. 表示征求对方
的意见或客气的请求。
will “决心,将要” sb will do... 表示意愿、打算

的变化。
