Andrew was able to walk when he was only eleven months old. A lot of them couldn't read or write. I wasn't able to do these quizzes. 但是要用was / were able to (不是could) 表示特定情况下的能力,意思是有能力做某事并确实做了这件事（通常做这件事有困难或需要努力,总之,不是一般的能力）,could没有这个意思： The injured man was able to walk to a phone box. 受伤的男子走到了电话亭.(肯定句) (意思是他有能力走到电话亭,而且他的确走到了那里.) was / were able to do的这一含义与succeeded in doing或者 managed to do的含义相同. 在否定句和疑问句中could和be able to这两种形式都可以用,意思没有区别： Detectives couldn't identify / weren't able to identify the murder. 侦探们无法确定凶手.(否定句) Could you get / Were you able to get tickets for the show? 你买到演出的票吗?(疑问句) 如果想要表示“（过去）有能力做某事但事实上没有做”这一意思,可用could have done这种形式,例句： He could have walked there, but he was too lazy. 他太懒了,他本可以步行去那里的.

It may not be easy. 当表示“某事是不可能的”这一意思时用cannot或could not： You can't talk to the dead. It couldn't possibly be poison. 可以用can表示“某事有时是可能的”这一意思： Such shifts in opinion can sometimes have a snowball effect. 9、表示过去的可能性： 表示过去的可能性用could have形式： He could have been doing research on his own. might have和may have也可以这样使用： The teacher might have known the local policeman. It may have been a dead bird. 当表示“过去某事有可能是...,但事实上不是...”这一意思时也可用could have这种形式： It could have been worse.

(当我们正在讲到正在发生的事情时不用be able to（我正在讲"Look, I can swim."这句话时我正在游泳）) This furniture can be assembled by anyone, with just a screwdriver.这种家具任何人都能装配,用一把螺丝刀就行了. （在“be +过去分词”前不用 be able to,这句话中的can不能用be able to代替） be able to 后面不能接动词不定式的被动形式,这就是答案.
