听力原文:M: What do you plan to do for Christmas?
W: No concrete plan, but I think I'll most likely go skiing in Montana and spend a few days in the mountains doing cross-country skiing.
M: I heard you are very good at skiing. Believe it or not, I haven't done any skiing in my life. I wish I could ski just like you.
W: Yeah, you could if you gave it a shot. You know, skiing is my love and the only reason I like it so much is because it gives me great pleasure to speed through the snow.
M: My parents and I vacationed in Montana National Park when I was little and I remembered we had great time going hiking. Now I feel like going back again.
W: Well, since we have two weeks' break for Christmas, you can spend a few days in Montana and I can give you lessons on skiing. That would give you some basics and hopefully you can ski like a professional in a few days.
M: Ski like a professional? No way. Actually, you do have a good point. I could spend some time in Montana and head back home for Christmas. Perhaps you could spend Christmas at my place too. My parents would like to meet you.
W: That would be great, since my folks will be in Jamaica for Christmas and New Year.
M: Oh, I am anxious to learn how to ski.
W: And you can bet I will be a very strict instructor.
M: No problem. I have been known to be an excellent student during my school year.
W: Well, maybe you won't be this time.
M: Really? I am looking forward to it now.
W: OK. Then, let's wait and see.
