Answer:
that's a lot to ask for. here are some tips:
a hook is what you say at the very beginning of a piece to catch someone's interest, e.g.
Imagine, for a moment, the scene. Your face is cold , your feet sore, and you hear your cousin crying nearby.
that would be a good hook for an essay on the trail of tears.
a thesis is an argument or claim that can be supported by your research. don't worry if your research turns out to back up a different view, you can always go back and change your thesis. an example of a thesis:
The river come to symbolize both division and progress, as it separates our characters and country while still providing the best chance for Huck and Jim to know each other.
the above example would be for a book report on the Adventures of Huckleberry Finn.
as for the body paragraphs, those are just backing up your thesis. Hope this helps!
