My teacher is making us write a book report. it has to have 2 paragraphs. i need to have characters, internal and external, setting, conflict and resolution, theme and opinion. how should i organize my book report.

I think he just wants you to explain all of those parts of the book like you would describe it to a friend. There's no set organization for a book report like that, especially not one so short. Just try to explain everything! If you're totally lost, I'd start by explaining the plot, then introduce the characters and the setting, describe the conflict, state the resolution, then close by explaining the themes or lessons in the book and give your opinion on it.
