In order to write a very good expository essay, you are going to have to mix up your thesis with your text. Many essays are structured so that they make a thesis statement, add evidence in the body and then call back to the thesis at the end. The typical expository essay will make frequent references to the thesis within the essay body in order to make its point.
How to create your introduction paragraph for your expository essay format
Use an interest-creating device or add a thesis statement. You can make statements of organization and then start concluding or add a transitional sentence. Do not reach a conclusion within the introduction, but start the conclusion process, which will run through the essay to the very end. The way you conclude your essay is mostly up to you, but many will make it an expanded version of their introduction’s conclusion.
Your first body paragraph
Start with your topic sentence and a brief transition followed by your major support. You then add context and quotation or some sort of concrete detail. You then add a little analysis. You then move on to the second major support, along with your context, your quotation or your concrete detail and your analysis. You then do the same for your third major support and you end your paragraph with your by either concluding or using a transitional sentence.
Your other body paragraphs
You should follow the same format as the first paragraph. Your job is to make up to three points per paragraph, and make sure you follow them with concrete details, statistics, or quotes. You cannot add in something that appears to be opinion until you conclude the paragraph. Your mini conclusions all add to the end conclusion. The reason that you put in your paragraph conclusions is because you are exposing an issue. It is a little like peeling back the petals from a closed rose bud.
How you should conclude your essay
You need to restate your statements of organization, but you should try to do it in separate sentences and try to word them slightly differently. You are probably going to have to restate your thesis in many cases. You then have a choice of concluding devices, but they are not limited. You can summarize all the mini conclusions that you made in order to show you have proved your point. Or you can create a conclusion based upon a complete summary of your entire article.
