【答案解析】[听力原文] Jolly Hubbard is a diet and nutrition expert who travels around the state to speak in middle and high schools. She primarily speaks to students in health classes but sometimes the school will arrange for her to speak to several different groups of girls. Her biggest concern is the emphasis American culture places on thinness and the negative way this affects girls today. Jolly has a Ph.D in nutrition but more important, she has personal experience. Her mother taught her to diet when she was only 8 years old. Jolly has created several different presentations, which she gives to different types of audiences and she tries to establish an emotional connection with the students so that they will feel comfortable asking questions or talking to her privately. She shows some pictures and images from popular culture of beautiful women and explains how computers are used to make the women look even more thin and beautiful than they are in real life. She describes how the definition of beauty has changed over the years and even from culture to culture. She then talks about health issues and the physical damage that can occur as a result of dieting. Finally, she addresses self respect and the notion that a person's sense of beauty must include more than how much a person weighs. Sometimes, Jolly feels that she succeeds in persuading some students to stop dieting. Other times she feels that she fails. Who does Jolly Hubbard primarily speak to?
