【答案解析】[听力原文]
   At only 28, Jamie Oliver now is an extremely successful and well-known chef, with his own acclaimed restaurant in the centre of London. He has made quite a few TV series, written four books, and still does a large number of shows a year. He doesn't have many free days any more. How did he make it big?
   Well, his rise to fame and fortune came early and swiftly. By the age of eight he had already started cooking at his parents' pub. It was an easy way to earn a little pocket money! After a couple of years in catering college, and a little time spent in France, he started working in restaurants. He worked under a few famous chefs in London before he was spotted by a TV producer at 21, and his life changed.
   Even though he had hardly any experience, he had a lot of enthusiasm for cooking, and was very natural in front of the camera. His first TV program featured his ripping around London on his scooter buying ingredients and cooking for his friends, all to a rock and roll soundtrack. The recipes were rare and simple—they didn't involve complicated cooking techniques and used lots of fresh ingredients and herbs. It attracted a completely new audience that previously didn't have any interest in food programs. Jamie Oliver became an overnight success.
   So what's his recipe for success? "A little bit of luck, a little bit of passion, and a little bit of knowledge!" he says.
   What changed Jamie Oliver's life?
