听力原文：M: Hello. W: Hello, Dad? M: Yes... Alice! How are you? Is there anything wrong? W: Oh, no. l just wanted to call and see how you and Mom were. It's been quite a while since I saw you last time. M: Oh, we're both fine. Your mother is down at the new shopping center. How's Jack? W: He's fine. He likes his work and was given a raise last month by Mr. Davis. We were all pleased about that. M: Yes, I think you should be. And how are the children? W: Well, Billy's home from school today. It's nothing serious, just a bad cold. And it's his birthday, too! M: Oh, I thought his birthday was May 24th. W: No, the twenty-third. M: Well, that's too bad. Tell him we'll send him a present. W: All fight. Sally's still taking dancing lessons. M: She must be pretty good by now. I'd like to see her sometime. And how is Ted? W: He's OK, too. He has a part-time job at the garage now. M: When are you coming for a visit? W: I hope we can come for a few weeks this summer, probably in July. M: That would be nice. Call again soon. W: OK, Dad. Give Mom our love. M: All right. Goodbye. W: Goodbye, Dad. Why did Alice call her father?
