【答案解析】[听力原文]
   W: Welcome back, Dan. How was your trip to Mongolia?
   M: I really can't complain. My daughter works at a university there, and she used some of her vacation time to show us around. Actually, one of her colleagues, a Mongolian woman, came with us.
   W: So you had a local showing you around? She must have taken you to some very special places.
   M: She did. It ends up that when growing up, she lived in yurts, you know, those Mongolian tents? Her mother and father still do, so we visited her family and experienced their traditional way of life for a few days.
   W: What an unbelievable experience! I can't wait to see photos from your trip.
