to be able to

Twenty minutes ago I wrote a text to practice English. Someone corrected me. Now I'm looking for some examples of how to use "to be able to". Please, correct me egain.

I think I have your meaning, but I couldn't find your earlier text.

to be able to = can

I am able to speak English (I can). I would like to be able to speak a foreign language fluently (I can't, but I want to). He is able to translate for me (he can do it). He might be able to come tomorrow (maybe he can).

I hope this is helpful. Good luck with your studies!
