M: (19)I have been studying too much and I really need a change. So I am just making plans to go away during January break. I grant to enjoy myself.
W: Really? You do deserve a great holiday. You did a great job. Where are you going?
M: I’m planning to visit New Mexico. How about it?
W: (20)My sister and I had the vacation there last year and we had a great time.
M: Did you get into Albuquerque?
W: Sure. We were skating all the time. I really love skating.
M: Is it far from the mountains?
W: Not at all. Even though Albuquerque is on the high plateaus, there are even high mountains near it. Just half an hour away from the city there is a snow-covered slope.
M: Well. As the mountains are just thirty minutes away, (21) I guess I should take my ice skate and my skis.
W: Definitely. You’ll need them.
M: I heard that the weather there is great.
W: It is. No humidity, moderate temperatures, but you do need to be careful about high altitude.
M: High altitude... What should I do about that?
W: Oh, just take it easy for a few days. Don’t go hiking up to the mountains or exercise too vigorously. Just do everything gradually. You’ll get used to it soon.
M: I’m sure I will be fine. And I will let you know all about my trip when I come back.
