The car fell into the ditch,but the driver __get out of it.A could B was able to 选哪一个?Why?
答案是B.could表示过去的能力,并不表示主语真的在执行这个动作.而was able to do 表示能够做并且执行了该动作.比如说 she could play the piano when she was five.她五岁时就会弹钢琴.并不是说她在谈,只是泛指她五岁时会弹钢琴,拥有这个能力而已.题中汽车栽进了水沟,司机从车里爬出来显然是真正执行了的动作.故选B.这种题目一项是英语教学中很难赢语言表述的.不知道我的回答是否让你满意.

B
be able to表示经过努力后能够做到某事。

选B
can 表示天生的能力
be able to 表示后天学习的技能
