①can表示能力“会，能” ②也可表示客观可能性。
③同时也表示“建议或请求”。可用Can I…?或Can you…?等结构，语气比较客气。
④表示“允许”或“请求允许”。其意思相当于may(可以)。但can比may用的更广泛。
⑤表示惊讶、怀疑、不相信等态度（主要用于否定句和疑问句），can't 还可以表示“不可能”之意。如： Mr Wang can't be at home. He is abroad now. (2) could表示过去的能力，更为客气、委婉的提出请求或陈述看法，有时则表示可能性不大。

（1）should的用法: should意为“应该”，表示主语的职责、义务或说话人的劝告，侧重于向别人建议怎样做才最合适。Should不如must那样语气强烈。should的否定形式为 shouldn’t.
（2）must的用法
① 表示“必须,应该”在第二、三人称中表示说话人的命令或要求。 ②must的否定有两个，当回答由must引起的问题时，否定回答用needn’t 或don’t have to，表示不必或无须。当表示“不应该，禁止”时用must not /mustn’t。 ③have to的含义与must接近，只是have to着重强调客观要求，must着重说明主观看法， ④表示推测，只用于肯定句，意思是“一定，大概”否定性的猜测应用can’t，不用mustn’t
