请牛牛们具体讲解一下can &be able to的区别 总是分不开，虽然知道can是表可能性，be able to表能力，不过具体应用还是不懂，请指教，举个例子好不。谢了

You can say that somebody is able to do something, but can is more

usual.

Bau can has only two forms: can and could. So sometimes it is

necessary to use be able to. For instance,

I will be able to get the car in a week.
