听力原文：W: Excuse me. Is this seat taken? M: No, it's not taken. Do you want to sit by the window? W: Oh, no, thank you. I like the aisle seat better. M: My name's John, John Smith. Please to meet you. W: I'm Mary White. How do you do? M: Do you live in New York? W: No, no. I'm from Florida. M: I'm too. But didn't you just get on? W: No, no. I just changed my seat. A man next to me was smoking, and smoke really bothers me. M: Do you have family in New York? W: No, no. But I do have very close friends in New York City. We like to go to the theatre together. How about you? M: Yeah. A son and his wife and their three children-my grandchildren. W: You must be excited. M: I can't wait to see them. W: Are you going to live with them? M: Yes. W: Permanently? M: Well, they want me to, but it's too early to know for sure. Some people don't mind being alone. I do. W: I understand. But tell me, why did you stop working? M: I retired because... I wanted to be with my family. I didn't want to be alone anymore! (23)
