听力原文：W: I enjoy going through second-hand 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？
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 50 cents.
W: But if this is the signature of someone who is well known, it might bring a lot more. 1 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". Maybe "Dobbins"？ Wasn'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.
