Yesterday I asked AI, could you please give me some sentences to practice the word “departure” ? AI did. And told me , I should say “for practicing” instead of “to practice”. Because it’s more polite. Ok, thanks, I learned. After a while, I asked AI, could you please give me some sentences for practicing the phrase “it never occurred to me ”? AI did. And told me, I should say “to practice”instead of “for practicing”, because it is more native . I am confused. I asked AI, have you made up your mind? So, my friends,what should I say?
