Each body paragraph must deal with a particular theme or text, and must start with a topic sentence. A topic sentence, similar to a thesis statement, will tell the reader what you plan on discussing. From there, you must justify your statements with evidence. A basic tool you can use is the . system – highlight a technique, identify an example and explain the effect – the effect will relate to your topic sentence, which in turn relates to your thesis! The conclusion of a body paragraph must sum up your argument for the paragraph and relate it to the thesis once again.
