You need to taste things to see if you like them. You know, some of the pieces at the exhibition were even for sale. The last one was on sale for $9,000. M: $9,000? Well, I may go and visit the exhibition tomorrow, but I'm not going tobuy anything. W: OK, let me know how it goes, won't you? And you might give Tom a call.

input question: M: Yes. I have to do a research paper for history. There's a major book that I need, but I can't find it. W: Did you try the card list? M: Yes, but it's not there. W: Well, if it's a recent book, it won't be in the card list. All information about books since 1995 is in the computer. I advise you to try that. M: No wonder! This book is published in 1998. W: All you have to do is to type in the title or the writer's name. M: Do you mean it will tell me whether the book is out or not? W: Yes, it will. It will also give you the due date if it is out. If the book is in the library, it will tell you where you can find the book. What was said before this conversation????

Answer: M: Hi! Weren't you two at the English Evening yesterday?
Q: M: No. What is it like? W: It's one of the most interesting cities in the United States. It has a French Quarter, with narrow streets and little shops. Many of the shops and restaurants are French. M: There's a lot of jazz music in New Orleans, isn't there? W: Yes. You hear wonderful jazz there. New Orleans and San Francisco are my two favorite cities. Have you been to San Francisco? M: No. What is it like? W: It has lovely views, and one of the most beautiful bridges in the world - the Golden Gate Bridge. It's a very hilly 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 arrive, your car needs good brakes. M: Do you have to drive? Can't you take buses? W: Well, most people who visit San Francisco ride in the cable cars. A cable car goes on tracks, and a strong cable pulls it up the hills. M: That doesn't sound very safe. W: Don't worry. Hundreds of people ride in cable cars every day. What was said before this conversation?
