The purpose of a narrative report is to describe something. Many students write narrative reports thinking that these are college essays or papers. While the information in these reports is basic to other forms of writing, narrative reports lack the "higher order thinking" that essays require. Thus narrative reports do not, as a rule, yield high grades for many college courses. A basic example of a narrative report is a "book report" that outlines a book; it includes the characters, their actions, possibly the plot, and, perhaps, some scenes. That is, it is a description of "what happens in the book." But this leaves out an awful lot.
The first sentence of the concluding paragraph uses the principal words from the quotations from each paragraph of the body of the paper. This summarizes those three paragraphs. The second and third sentences provide observations which can also be considered a summary, not only of the content of the paper, but also offers personal opinion which was logically drawn as the result of this study. The last sentence returns to the Edgar Allan Poe-Stephen King relationship that began this paper. This sentence also provides a "wrap-up" and gives the paper a sense of finality.
