请牛牛们具体讲解一下can &be able to的区别

cherrychengyue

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.

另外，GMAT常考的一个错误用法是be able to be done

cherrychengyue

也就是说不需要从意思上（能力还是可能性）加以区分吗，只要注意时态看哪个更合适，又没有明显错误就行吗？谢谢

各位，语言改正错误考试中会不会出现整体不是一个句子的情况？谢谢

The work of mathematician Roger Penrose in the early 1970s, on the geometry of what are called aperiodic tiles, turned out to describe the architecture of a previously unknown class of crystals. 有错误吗
