     (Chen Hong and Peter Johnson are talking about two American cities:  New Orleans and San

       Francisco. )

Peter: New Orleans and San Francisco are my favorite cities. Have you ever been there?

Chen: No. I've been to neither of them.

Peter: Well,  New Orleans is one of the most interesting cities in the United States. It has a French

          Quarter (地区 ), with narrow streets and little old shops.  Many of the shops and restaurants are

          French.

Chen: There's a lot of jazz (爵士) music in New Orleans, isn't there?

Peter: Yes. You can hear wonderful jazz there.

Chen: And San Francisco?

Peter: It has lovely views and one of the most beautiful bridges in the world—the Golden Gate Bridge.

          It's   a very hilly (多山丘的) city. The hills are in the middle of the town, so you have to walk up

         and down hills when you go anywhere. When you drive, your car needs good brakes (刹车).

Chen: Do you have to drive? Can't you take buses?

Peter: Well, most visitors to San Francisco ride in cable cars (缆车). A cable car goes on tracks (轨道),

          and a strong cable pulls it up the hills.

Chen: That doesn't sound very safe.

Peter: Don't worry. Hundreds of people ride in cable cars every day.
