Those are really good ideas. I think I'll choose any famous people. It could be The Bee Gees, my favorite band. Thank you very much for your ideas. Wish me luck!

Did your teacher say what s/he wanted to see? There are so many things. If you choose something you feel you already know a lot about, you can concentrate on the English and not worry about forgetting the material when you present. It's also nice if the classmates and teacher don't know a lot about that topic. How about a hobby / special interest of yours? A place you've visited? A famous person? An author or filmmaker? Something from the area health and fitness? or or or?
