Maybe you can make a informative speech on the worlds most deadliest diseases, but a certain question in particular, does it need to be about something English related? If so I give another topic that may work for you, maybe Athenian survival, or their agricultural surplus.
Pick a topic you know a lot about and is easy to write about. If you dont really know a lot about a topic pick one that is easy to research like dogs or the importance of exercise.
