解析：[听力原文] 5-8
W: Whose book is this
M: It’s mine. Why do you ask
W: Could I borrow it I’ve been wanting to read it.
M: Be my guest, but I’ll warn you. It’s not as good as they say.
W: What’s the matter with it
M: Well, for one thing the plot is highly improbable and also, the characters seem more like paper dolls than people.

M: I’ve been a fan of his for a long time too, but he really flubbed on this one!
W: What did the review say
M: They were mixed — some good, some bad. My review, bad!
