精讲点拨：
can 的用法：
(1). 表示能力，意为“能，会”。

如：I can’t swim. 我不会游泳。

(2). 表示客观可能性，意为“可以，可能”。

如：The big cinema can set 2,000 people. 那家大电影院能坐2000人。

(3). 表示允许（和may意思相近），意为“可以”。

如：You can have the book when I have finished it. 书我看完了可以给你。

must 的用法：
表示“必须，应该”，其否定形式为must not / mustn’t，表示“不应该，不准”，在回答有must的问句时，否定形式用needn’t 或 don’t have to，而不用mustn’t。

如：----Must I be home before eight o’clock? 我必须在8点之前回家吗？
----Yes, you must. / No, you needn’t.是的，你必须这样。

/ 不，你不必。

must 与 have to
(1). must 表示说话人的主观看法；而have to 强调客观情况迫使人不得不做某事。

(2). must 只能表示现在“必须”，表示过去的事情要用had to. have to 有时态、人称和数的变化。

(3). must 与 have to的否定意思不同。

如：You mustn’t do that. 你千万不能做那件事。

You don’t have to do that. 你不必做那件事。

（相当于needn’t）
