1) He's being late for school.
He has been late for school.
2) He's being ready for school.
He's doing ready for school.
Actually, I'd like to use the word BEING in the sentence. So, please try to correct these sentences with reference to word "BEING".
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
appreciate you so much.
He keeps being late for school.
Your second sentence should probably read........
He's getting ready for school.
He is ready for school.
Which is appropriate depends on what you intend to say.
buggles (not a teacher)
