【求权威】选词填空,可改变形式：When he was yong,he -----play the violin very well (can;be able to)
答案上是把be able to 改成was able to.
我觉得为什么不能把can改成could填上去呢?

e able to 表示主语具备完成后面所提到的行为的能力.
can 除了可能性外,还表示本身具有某种固有的能力或技能.
如果孤立地看,用 could 和 was able to 都可以,不过用 could 会出现两种含义,一是有可能把提琴拉好,一是有能力把提琴拉好.在没有上下文的时候容易产生歧义.
本题本意是企图表示他在小时候具备完成把小提琴演奏得很好得能力,这种能力是经过后天努力而习得的,而不是无师自通,天生下来就具备这种固有的能力.我想,这个句子可能是出自一篇有上下文的完形填空,而不是一道单纯的单项选择题.
再问：你想错了这确实没有上下文。
再答：如果没有上下文，你的想法也有一定道理，但是比较起来，根据最佳选择原则，还是 be able to play 贴切一些，这时因为：用 was able to 只含有一种意思，即“具备能力”；而用 could 则含有两层意思，一是“可能性”，一是“有能力”。
