【答案解析】[解析]
W: I enjoy going through secondhand bookstores, don't you? It's interesting to see what people used to enjoy reading. Did you see this old book of children' s. stories?
M: Some of these books aren' t so old, though. See? This mystery was published only six years ago. It costs seventy-five cents. You can' t beat that.
W: Hey! Look at this!
M: What? Are you getting interested in nineteenth century poetry all of a sudden?
W: No. Look at the inscription. Someone gave this book as a present and wrote a note on the inside of the front cover. It' s dated 1893. Maybe it's worth something.
M: Everything on that shelf is worth fifty cents.
W: But if this is the signature of someone who is well known. It might bring a lot more. I hear William Shakespeare' s signature is worth about a million dollars.
M: Oh? I can hardly read what that one says. Who wrote it?
W: The name looks like "Harold Dobson". May be "Dobbins" ? Wash' t he a politician or something? I' m going to buy this book and see if I can find a name like that in the library.
M: Good luck. Your poetry book may make you rich. But I' ll bet my seventy-five-cent mystery is a better buy.
