听力原文：M: Hello. W: Hello, Dad? M: Yes. . . Alice! How are you? Is there anything wrong? W: Oh, no. I just wanted to call and see how you and Mom were. It 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 shopping. W: For a new dress? M: No, for shoes this time, I think. How' s Jack? W: He' s fine. He likes his work and was given a raise last month by Mr. Davis. We were all pretty 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 right. 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 loves working on cars and has a part-time job at the garage now. M: Well, it' s certainly good to hear your voice. When are you coming for a visit? W: Not for a few months, I' m afraid. But 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. Nice talking to you and glad everything' s all right. Give Mom our love. M: All right. Good-bye. W: Good-bye, Dad. Why did Alice call her father?
