For the final copy of your paper, you will need to include and introduction and a conclusion. Below you will find some suggestions for an introduction. A conclusion should be about the same length, repeat the thesis and paragraph topics, and then made some extension to broader ideas that your paper has helped reveal.
Your introduction to your expository paper should be about 5-6 sentences long. The last sentence should present the thesis of your paper: One of the ways Greeks used Mythology was to explain the natural world around them. Of course, you’ll want to phrase this in your own words. The final sentence should also present the paragraph topics or categories of your discussion: Plants, Animals, Trees, Geographical locations, etc.
Your first 4-5 sentences should present background information that is in some way connected to your paper. You might consider a few sentences on
• Basic information about Greek gods and goddesses
• Comments on mankind’s desire to explain things
• Reflections on different types of Mythology in the world
• Contrasts to how mankind uses science to explain elements of the world today
There are many possible options, so this list does not present your only possibilities. Also, remember this is formal voice, so you still want to avoid the pronouns “I, you, we, our”.
