情态动词，表示说话者对某一动作的看法和态度，包括可能、怀疑、允许、愿望、必要、猜测等。can(能、会),may( 可以),must( 必须、一定)等。

(2)变否定句时，直接在情态动词后面加not,无需加助动词。he can’t play the guitar well.
he can’t answer the question. you mustn’t be late.
(3)含有情态动词的句子变一般疑问句时，须将情态动词提前。can you help me? must i go there at once?
(4)can 可表示能力、允许、可能性、怀疑猜测，意为“能，会，可以。”can’t, 意为“不能，不会，不可以。”，还有“不可能”之意。
