Can you lift this box on your own?Are you able to lift this box alone?的区别
can 与 be able to do 的区别:be able to与can 都可以表示能力.can泛指一般能力,be able to 则主要指具体做某件事(比较特殊的事情)的能力.如我们可以说:I can swim 和 I am able to swim 这两个句子意思是一样的,简单来说 can 与 be able to 都是用于现在时的话,基本上没有区别.
而alone 与 on one's own 的意思在此处无异,因此Can you lift this box on your own?Are you able to lift this box alone?这两个句子意思上没有区别.
已尽努力回答,望楼主满意,

can 泛指一般的能力,而 be able to 则主要指具体做某件事的能力。
on one's own=alone
区别不大
