单项选择题

[听力原文]
M: Hi, Karen! Fancy meeting you here!
W: Fancy meeting you here, too. Jack! How are you It’s been ages since we met last time!
M: I’m fine, thank you. Seeing you now just reminds me of the good days we spent together in school.
W: Me too. Do you usually come here
M: Right, 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
W: Some of these books aren’t so old, though. See This mystery was published only six years ago. It cost seventy-five cents. You can’t beat that.
M: Hey! Look at this!
W: What Are you getting interested in nineteenth-century poetry all of a sudden
M: 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’ll worth something.
W: Everything on that shelf is worth fifty cents.
M: 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.
W: Oh I can hardly read what that one says. Who wrote it
M: 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.
W: Good luck. Your poetry book may make you rich, but I’ll bet my seventy-five cent mystery is a better buy.
