听力原文：W: What else has made a deep impression on you during your visit to America? M: Hmm... I should say I'm a little surprised to see so many different kinds of ethnic restaurants in your country. W: Yeah. In America, you can enjoy the cooking of different countries, such as that of China, Italy, India, and France. M: Is it because immigrants miss the traditional foods of their native lands? W: Not necessarily. Some of them open restaurants because they don't have the skills or qualifications to do anything else when they arrive in the US. M: Are these ethnic restaurants also popular with native-born Americans? W: Sure. Americans love to try new and unusual foods. M: I see. No wonder it is sometimes a bit hard to find a 'traditional' American restaurant. W: You are right. When it comes to food and eating, America truly is a melting pot. Q6.
