听力原文：M: How much are the carnations and tile roses? W: One dollar for each carnation and (9)one and a half for each red rose. M: (9)Then I'd like a dozen red carnations and half a dozen red roses. W: I bet it's for your mother, (8)as it's Mother's Day today. M: Well, not completely true. (8)It happens to be her birthday. W: Oh, really? I guess she must be very happy to receive these beautiful carnations from you. M: Yeah, she will. She really likes flowers. So I buy her some every year. I'd just wish they would stay fresh longer than they do. W: (10)Put a little sugar and vitamin C in the water. They'll stay fresh for days. M: Really? I'll tell my mother. And thanks for your suggestion. W: That's all right. Happy birthday to your mother! (8)
