With a Classic Structure
In a speech where you're trying to persuade someone, the classic structure is called "Problem-Solution." In the first part of your speech you say, " Here's a problem, here's why things are so terrible. " Then, in the second part of your speech you say, " Here's what we can do to make things better. " Sometimes it helps to persuade people if you have statistics or other facts in your speech. And sometimes you can persuade people by quoting someone else that the audience likes and respects.
Practice organizing your writing. Before starting your written response allow 2-5 minutes to make an outline of your essay. Do not worry that the time is running, a good outline will save you lots of troubles and time while writing. The essay outline should include the major ideas for the paragraphs in 2-3 main phrases per paragraph, as well as some examples and supporting details. Do not write complete sentences, but some words and phrases that may help you follow that outline and add additional information to develop a well-organized and coherent essay.
