情态动词没有人称变化、接动词原形。can表能力(不能与情态动词连用),be able to表能力、事件、突出不容易、可以与其他情态助动词连用(used to、might)

表将来:在表将来的时候can必须与明确的将来时间、不能与will连用,而be able to可以与will连用

表现在完成:只能使用be able to,因为can没有过去分词形式

但be able to可以表事件(具体一件事情做到了),有能力(泛泛而谈的能力)去做不代表能够做到,而be able to可以表事件(具体一件事情做到了)

例1说Jack年轻的时候可以打败任何人,但没有提及具体的人/事情(泛泛而谈的能力)

例2说Jack做的比赛,Jack昨天的比赛打败了Andy,有具体的事件只能用be able to。如果用can来代替,会感觉到Jack具备打败他的能力,但是没有打败他的错觉

escape写成一般过去时就有表成功的意思(客观事实),添加was able to一方面表成功逃脱另一方面表不容易
