Tia Betances was concerned about taking a speech class. (33) Not having any experience as a public speaker, she got butterflies in her stomach just thinking about talking in front of an audience. But when the time came for Tia’s first speech, she was determined to make it success.
    Tia chose the Special Olympics as the topic for her speech. Her younger brother suffered from Down’s syndrome, and for the past five years Tia had worked as a volunteer at the local Special Olympics competition. (34) The purpose of her speech was to explain the origins, events, and philosophy of the Special Olympics.
    As Tia spoke, it became clear that she cared deeply about her subject and genuinely wanted her audience to care about it too. Because she was intent on communicating with her audience, she forgot to be nervous. She established eye contact with her listeners and (35) spoke clearly, fluently and dynamically. Soon the entire class was engrossed in her speech.
    She combined her enthusiasm for her topic with thorough preparation and she scored a triumph in the  speech class. Afterward, Tia conceded that she had surprised even herself. "I could hardly believe it," she said. "Once I got through the introduction, I didn’t think about being nervous—I just concentrated on what I wanted to say. It was even sort of fun"
