“I am able to play the piano”中用了be able to词组,to之后的动词为什么不用动名词（v+ing)的形式?

to 后面不一定非要接动词原形 be able to do sth是一个固定搭配；这里的to do是动词不定式.而i'm used to doing this that way.(我习惯用那种方式解决问题)这里的to 是介词,介词后面跟名词或者名词类词（也就是你所说的v+ing形式）.

“I am able to play the piano”中用了be able to词组,to之后的动词为什么不用动名词 I will be able to为什么要用be而非I will am able to be able to 的同义词组是什么? _Are_____you able to play the piano for us tomorrow?　为什么用Are I'll be able to dress more casually.和I'll am able to dress m I am able to protect you and be fond of would be able to和be able to的区别 be able to 和will be able to 的区别 be able to 的用法 be able to的同义词 be able to的词性 be able to的用法
