Your body paragraphs should analyze concrete examples from the text you’re discussing. Each topic sentence should hearken back to your thesis, further proving your point and discussing how a specific instance of a tool employed by the author contributes to the text’s purpose. In most cases, each body paragraph should consist of a topic sentence, a short quote from the text, an analysis of that specific quote and how that quote furthers the author's purpose. Keep your quotes short and include at least three times more analysis than quoted text.
Notice that since I took a direct quote from John Smith's book, I placed those words in quotation marks. Notice also that I placed the date that the book was published directly after the author's name in parentheses--this is proper APA format. Finally, notice that because I explained WHO wrote the book and WHAT book it comes from, the reader is easily able not only to find the source on his/her own to check my facts, but the reader is also more likely to believe what I have to say now that they know that my information comes from a credible source.
