can无人称和数的变化，过去式为could；be able to有人称、数和时态的变化。
can泛指一般的能力或一种客观可能，而be able to更加强调通过后天的学习和努力获得的能力，或者在某个场合和背景下，具体做到了某件事。
Edison always wondered why hens could hatch chickens while he was not able to.A big fire broke out in ABC hotel yesterday. Luckily, everyone was able to run out of the building. 在第二个例句中was/were able to do sth.相当于managed to do sth. /succeeded in doing sth.-I feel so bored.-You can watch TV.Could/Can you wait a few days for the money?-Could/Can I use your bike?-Yes, you can. / No, you can’t.②表示请求、建议、允许、许可，用could 比can语气更委婉(回答用can)。
