Persuasive Paragraphs

Persuasive or Argumentative paragraphs are paragraphs that try to convince the reader to agree with something.
Writing a good paragraph just takes practice. You will be able to write well if you keep at it! Anyone at all can learn how to write a good paragraph, even if they don't make perfect grades or speak wonderful English. All you have to do is be willing to practice writing, and you can do it! A hortatory exposition is a special type of argument that is written in specific language. To write hortatory exposition, you use words that focus on the writer instead of on the reader (I, me, mine). You also use more abstract language such as passive voice ("it was done" instead of "they did it") and present tense instead of the usual past tense ("I am in town" instead of "I was in town"). Hortatory exposition is just an argument which is phrased in a less emotional, more passive voice.
