Are you looking for the structure? If so, set your paper up as if you were writing an expository essay. If you are arguing, take your side and back it up with facts. You don't want to use pronouns such as I or my. Your teacher will not care about your opinion. Make sure your intro paragraph starts with a bang. You want to grab the attention of the reader. Try using a quote or foreshadow a story about his life. Your thesis statement should be the last part of intro. Hopefully this helps. My students are working on several papers this week. Must be a busy time for writing!!! Good luck. Please let me know if you need any help.
