How do you interpret this pattern so that your reader will understand the book, essay, poem, speech, etc. What philosophical, moral, ethical, etc. Examine how characters are presented in a story. Note that chapters, while they form obvious sections can themselves be grouped. This means that you must quote and interpret passages that demonstrate or support your argument.
Quotation is usually stronger than paraphrase.
It puts me in a good mood before I start reading. Walden is a book comprised of chapters. Each of these chapters could also be called an essay. Within these essays, Thoreau sometimes tells stories. The book itself is not a story, but closer to a narrative, which is non-fiction.
