Examples and illustrations are a basic kind of evidence and support in expository and argumentative writing.
In her essay about anorexia nervosa, student writer Nancie Brosseau uses several examples to develop a paragraph:
Another problem, lying, occurred most often when my parents tried to force me to eat. Because I was at the gym until around eight o'clock every night, I told my mother not to save me dinner. I would come home and make a sandwich and feed it to my dog. I lied to my parents every day about eating lunch at school. For example, I would bring a sack lunch and sell it to someone and use the money to buy diet pills. I always told my parents that I ate my own lunch.
Look at your own topic. What examples and illustrations would help explain your subject?
