听力题 M: So you''re visiting San Francisco? W: Yes, I just got here yesterday. And you? M: I''m a native. W: Oh, really? Everyone else I''ve met so far has been a tourist like us. I was beginning to think that there were no natives. . M: Well. San Francisco has a lot of different ethnic groups so you might think you''re seeing a lot of foreigners. But actually, the city has a population of about 700,000. W: What are the different ethnic groups? M: After whites, the largest one is black. W: I thought it was Chinese. M: It''s true that San Francisco has the largest Chinese community outside of 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 all over 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 and things like that. W: What about the Japanese? Doesn''t San Francisco have a large Japanese population too? M: Actually there are only about 12,000 Japanese people here, but we do have an area called "Japan-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.
