听力原文：M: Hi, Wendy. What are you doing for summer break? W: (7/8) I would like to Italy and work at a restaurant in Florence. My uncle owns a restaurant and he will offer me a job for the summer. M: That would be a wonderful summer. W: Yes, I really want to go. The problem is my father had a heart attack three weeks ago. He is out of the hospital now, but he cannot do much around the house. So I need to help my mother. It is such a dilemma. M: Yes, I could see that would be a very difficult decision... W: What about you, Steven? What are your plans for the summer? M: Well, I have a dilemma, too. I would love to go to Nepal and volunteer with a NGO that could require me to instruct local residents in engineering skills. However, If I do get accepted, I won't be making any money and I need money to return to university for my final year in September. W: I can see your problem. Can't you borrow money from financial aid for your final year? M: Probably, but I hate to start off with a lot of debt. Engineering fees are rising by 10 percent next year. W: No, but if you have the opportunity to take an interesting job in Nepal, and be of service, I think that would be wonderful. M: You are probably right. I appreciate your advice. What is the main topic of the conversation?
