阅读理解。 Almost 20 years ago, a few days before Christmas, Roni Austin's 6-year-old daughter, Lauren, went to a Jack in the Box in Carlsbad and ate a hamburger. She got sick, was rushed to a hospital and never came home. Lauren was the first to die in a multi-state E. coli outbreak that killed three other children and sickened 700 people. Like many people, Austin had never heard of E. coli before. At first bewildered, and then angry, Austin soon became the face of food-safety reform in California and beyond. She co-founded a nonprofit group, Safe Tables Our Priority (STOP), and pushed successfully for legislation (立法) requiring E. coli to be a reportable illness, so outbreaks could be followed and stopped sooner. Nervous initially to be in the spotlight, she learned not to fear politicians for the beef and fast-food industries. She was in the Oval Office when President Clinton signed the most sweeping changes to federal food-inspection law in the 1990s. She was in Sacramento when a state measure named after her daughter passed, indicating minimum cooking temperatures in restaurants. Austin, , is not sure she has much choice. Every time she thinks she's handed off the baton (指挥棒) to others, though, something brings her back. A phone call from a parent who has lost a child to a food-borne illness. A news story about another outbreak. An at La Costa Heights Elementary School, where redheaded Lauren was in first grade and where a memorial garden was planted in her honor. Fixing food safety meant putting her career as a fashion designer on hold and flying 10 times to Washington DC to testify. It meant going to Sacramento to speak a half-dozen times. She's not fond of the legislative process. Asked what she's proudest of in her way through all that, she said,"That I didn't give up." 1.
