A. can 與be able to 均表示“能”，指現(xiàn)在或過去“能力所及”時(shí)，兩者可通用。例如：

He can / is able to speak English. 他會(huì)說英語。

I could / was able to run very fast when I was a boy. 我小時(shí)候就跑得快。

B. be able to的過去式還可以表示一種“經(jīng)過努力做到”的意思，can的過去式則沒有這種含義。例如：

He started late， but he was able to catch the eight o’clock train .他出發(fā)晚了，但他努力一把，還是趕上了八點(diǎn)鐘的火車。

C. can通常只用于現(xiàn)在、過去兩種時(shí)態(tài)，而be able to還用于將來時(shí)和完成時(shí)態(tài)。例如：

He has not been able to come since he got hurt. 自從他受傷，一直沒有能來。
