Part one is the introduction which always includes two main functions. The introduction should (1) get the reader's attention and (2) tell the reader what the essay is about. Telling the reader what the essay is going to be about is also called "Stating your Organization." If your introduction is good, it will not only help your reader anticipate what your essay is about, but it will also help you organize the main points in your own mind, possibly even before sitting down and putting thoughts to paper.
