Thesis Statement
To craft an expository paragraph, first pick a broad topic that grabs your interest. It could be anything from the vast arena of modern culture like TV, sports, music, food, or movies. The process of writing begins once you've chosen a broad area to explore. Your next step is to refine this broad subject into a more focused topic suitable for a paragraph. For example, starting with the broad subject of sports, you might zoom in on professional football. However, that's still too broad for a single paragraph. You'd need to narrow it down even more. You might end up with a topic like the increasing reports of head injuries in the NFL. This shows how you start with a wide subject and funnel it down to a specific topic.
