Passage 2
There is nothing new about TV and fashion magazines giving girls unhealthy ideas about how thin they need to be in order to be considered beautiful. What is _1_ is the method psychologists at the University of Texas have come up with to keep girls from developing eating disorders. Their main weapon against superskinny (role) models: a brand of civil disobedience _2_ “body activism.” Since 2001，more than 1,000 high school and college students in the U.S. have participated in the Body Project, which works by getting girls to understand how they have been buying into the _3_ that you have to be thin to be happy or successful. After critiquing (评论）the so-called thin ideal by writing essays and role-playing with their peers, participants are _4_ to come up with and execute small,_5_acts. They include slipping notes saying “Love your body the way it is” into dieting books at stores like Borders and writing letters to Mattel, makers of the impossibly _6_ Barbie doll. According to a study in the latest issue of the Journal of Consulting and Clinical Psychology, the risk of developing eating disorders was reduced 61% among Body Project participants. And they continued to exhibit _7_ body-image attitudes as long as three years after completing the program, which consists of four one-hour _8_. Such lasting effects may be due to girls’ realizing not only how they were being _9_ but also who was benefiting from the societal pressure to be thin.“These people who promote the perfect body really don’t care about you at all，” says Kelsey Hertel, a high school junior and Body Prqject veteran in Eugene, Oregon. “They _10_ make you feel like less of a person so you’ll buy their stuff and they’ll make money.”
