Let’s think about the type of writing that most of us encounter in our daily lives. When you pick up and read a non-fiction book, magazines, or newspaper article, the author uses expository writing to inform you, the reader, about the topic. At school, students are required to submit school exams and research papers as a means for their teachers to grade their progress. Finally, at work, people are required to produce business reports and memorandums to inform their superiors and co-workers about the occurrences that take place at other levels of the company. In addition, oral exposition is primarily observed in oral academic presentations, business talks, and speeches that are delivered to a group of people. As each of these different cases illustrate, expository writing and speech surround us in our everyday lives. The primary intent here will be to help move students closer to mastering the hows, whens, and wheres to select different oral and written expository styles for a variety of real world contexts.  Formal exposition is a variation that requires formal tone, so there are no personal references (such as I and you), no contractions (such as I’m or you’re; can’t or didn’t; weren’t or wasn’t), no references to yourself or to me.
