它与can 的区别就在于be able to 有人称和数的变化,而can 没有。
举例:我们可以说:If he work hard, he will be able to pass the exam.
而不能说:If he work hard, he will can pass the exam. able [形容词,不是动词!] =能; 能够;有才干
(1) He was able to open the door;
(2) He will come if he is able. 能够的
(3) The brakes were able to be fixed.
(4) Maria is a very able nurse. 有才干的
(5) They are bright, intelligent, able and confident.有才干
(6) I'd like to be able to study in peace.能够 如果细分的话:be able to表示有能力做某事,强调一种后天的,经过努力或培训后得到的能力。can表示一种天生的能力。
而它们的区别更多的体现在适用范围上,can表示能力时,因为时态限制,只能表示现在(can)或者过去(could)所具有的能力。
而be able to则可以表示过去(was、were able to),现在(am、is、are able to),将来(will be able to)三种时态的能力。

able [形容词,不是动词!] =能; 能够;有才干

2.位于情态动词后
3.位于句首表示条件
