an exposition is basically and arguement written down as a speech.

What is a thesis point?

a thesis point is one of the main points argued within an exposition.

How is an exposition text type structured?

an exposition is started with an introduction stating what you are trying to argue and why, then  you come in with your thesis points, just stating what they are, breifly. Now you just write a detailed explanation on your thesis points, preferably in the order you wrote them in the introduction.  To wrap it all up you will need a summary of all this in what is called a conclusion, a breif description of everything you have just written
