If every essayist felt pressured to show all their cards in the opening paragraphs of their essay, they would rightly find that a burdensome restriction.
Keep the essay question in mind. You may, for example, follow your thesis with a brief road map to your essay that sketches the basic structure of your argument.
If you wish to summarize—and often you must—do so in fresh language. Use 'signpost' words in your writing. Try to use a working definition from an expert in your subject area rather than referring to a general dictionary definition.
Some of that time can be more usefully channeled into planning and writing. I think these questions have a point, I think they deserve to be answered. This becomes increasingly important as essays become longer and more complicated.
An essay is our opinion on the text, this is reflected in any statement we make. The following examples from Model Essays One and Two show how concluding paragraphs are developed. Make use of detailed references to the play in your response. If your discipline encourages personal reflection, illustrate your concluding point with a relevant narrative drawn from your own life experiences.
