Sue broke two keys on her typewriter. Is this active passive

in june, we will have been married for eighteen months. (i am assuming this is what you want? the sentence, as you have presented it, is grammatically incorrect--   you want it corrected, yes? )

in my opinion, ap calculus was the most difficult. i often struggled with it a lot. however, i have gotten a lot better.

i literally just read the book and studied it for months so i could you, but i need to know where these questions are coming from. they are too general.
