Consider who is being addressed or discussed in the original text. Think about what is being addressed or discussed. Mention where the text is set, if relevant. Finally, determine why the author is discussing or addressing the subject matter in the original text. For example, if you are writing about The Great Gatsby, you should address the two main characters in the novel (Jay Gatsby and his neighbor/the narrator Nick Carraway). You should also focus on what occurs, briefly, in the novel, where the novel takes place, and why Fitzgerald explores the lives of these two characters. Aim to have one to three supporting points at the most, as you do not want to make the summary paragraph too long. Use events from the text as well as quotes or points in the text to support your opening line. For example, if you are discussing an article, you may use the author’s key arguments in the article as supporting points. If you are discussing a novel or short story, you may use the key events in the story as supporting points. Do not copy or paraphrase the original text. Use your own words in the summary. Avoid using the same language or word choice as the original text, unless you are quoting it directly. Keep in mind a summary paragraph should simply state the essential information in the original text. You do not need to present an opinion or argument about the text in the summary paragraph. This can be done in a separate paragraph or section in your paper. A summary paragraph should be no longer than six to eight sentences. Once you finish a draft of the summary paragraph, read it over and revise it so it is short and to the point. Remove any sentences or phrases that seem redundant or repetitive. You may also show the summary paragraph to a writing instructor or a friend to get feedback on it. Ask the person to make sure the summary paragraph includes the essential information about the text in a concise, clear way.
