听力原文：W: Excuse me. Do you know how many stops we have until we reach Oxford? M: Just three more stops. We left London at 10:00 so it will take about 45 minutes before we pull into the train station. Just enough time to have a bite of lunch. W: So that would put us in at about one, I guess. Great, I just got in from New York on the 8 a.m. flight. I'm going to be giving lectures on international development at Oxford for a year. M: I think you'll enjoy yourself there. I graduated from Oxford myself years ago. I'm on my way back for a business meeting. Where are the speakers?
