That is exciting to have a presentation project! 😊 In Japanese, people say 「テーマ」. But the English pronunciation is different. We say "theme". 🙂

Hi! As a topic of a presentation I would choose something I can develop a story from. For example, I would describe my childhod friend, what we've been through, some funny or enlightening stories and adventures, how we travelled together, how we helped each other. What this friendship taugh me, and so on. If to pick up a thing, I would choose one of the New Years presents I've got or prepared. It would be easy to develop a story from this, I suppose. Good luck with the presentation!

Well, that's quite a wide topic. You could talk about a relative or a friend that helped you in times of need or for whom you have a lot of respect and explain why. You could even talk about a pet for example. Those of course are just a few suggestions.
