听力题 M: So you are visiting San Francisco? W: Yes, I just got here the day before yesterday. And you? M: I am a native. W: Oh, really? Everyone else I''ve met so far has been a tourist like us. I was beginning to think that maybe there were no natives. M: Well. San Francisco has a lot of different ethnic groups, so you might think you are seeing a lot of foreigners. But in fact, the city has a population of about 700,000 people. W: What are the different ethnic groups? M: Well, after whites, the largest one is blacks. W: I thought it was Chinese. M: It''s true that San Francisco has the largest Chinese community outside Asia. But there are many more blacks here than Chinese. W: That''s interesting. Don''t most of the Chinese people live in China-town? M: Well, no, they live throughout the city, but China-town is definitely the center of Chinese culture here. That''s where you''ll find the best Chinese restaurants, bookstores, art theaters, things like that. W: How about the Japanese? Doesn''t San Francisco have a large Japanese population too? M: No, actually there are only about 12,000 Japanese people here, but we do have an area called "Japanese-town" that has Japanese restaurants and bookstores. W: You seem to know a lot about this city. M: Well, most San Franciscans think their city is pretty special. We like to talk about it. Besides, I teach ethnic history at the university here. W: No wonder you know so much!
