Take your assertions a step further in this part of the conclusion. Because the first and last paragraphs of your essay leave the strongest imprint on the reader's mind, make sure the writing is especially tight. Look for beauty of language in these parts, especially toward the end of either paragraph. Show us not only that your thoughts are cohesive, but that your speech is compelling and gorgeous, too. Improve your writing by using active voice and eliminating passive voice.
Passive voice takes the being verb, and causes wordier, irresponsible sentences.
Putting sentences into active voice strengthens your writing almost immediately. Ask yourself who acts in the sentence, and make that person or thing your subject. The object acted upon should not be the subject of your sentence. It's solid as a rock. He takes a raincheck.
