听力原文:M: Say, Rason, what are you watching? W: An old Japanese film. I wonder if I'm going to spend all my next year there, I'd better start familiarizing myself with the culture. M: You mean you are accepted into the program? W: Yes. M: That's wonderful. You must be excited. W: Excited and nervous. You know I owe a lot to Professor Mercheno. He wrote a letter of recommendation for me and he bought me a set of practice tapes and a book which goes with them. Just so I can work on my basic conversation skills. M: How much Japanese can you understand? W: Not a lot at present. But I signed up for intensive Japanese this semester. M: I Wish I were as talented as you are in foreign languages. I'd like to study abroad. W: Then why don't you? The university has lots of overseas programs that don't require mastery of a foreign language. The tuition is about the same. You just have to be the kind of person who is receptive to new ways of looking at things and willing to adjust to a different kind of life style. M: I had assumed that all programs require you to know a foreign language. I might check into this. W: You won't regret it. What is the woman doing when the man interrupts her?
