W: Wow, it’s freezing in here! Why is the air conditioner still on? What’s the matter?
M: I turned it on just now. (12)I just finished my morning exercising as usual and I’m sweating like a pig.
W: That’s no reason to turn the air conditioner on full blast! I’m cold. I’m turning on the heat for a little while. Otherwise, I cannot finish doing the housework before going to work.
M: Are you crazy? (13)It’s 70° outside!
W: I’m no crazier than you are. How come you can turn on the air conditioner and I can’t turn on the heat?
M: I only turned on the air conditioner because (13) it’s so humid outside, and it was taking a long time for me to cool down. If you’re cold, we should just open the windows and doors, and we’ll get some fresh air in here. It’ll heat up again pretty quickly.
W: What should I do in the meantime? Put on my winter coat or crawl under the covers?
M: No need to do that. Calm down. Just go sit outside and wait. I’ll do something to make both of us comfortable. I’ll get myself a glass of iced tea and (14) I’ll get you a cup of hot tea. How does that sound?
W: That sounds OK. Leave it to you to come up with the best idea of the day! What about the housework?
M: Take it easy. (15) We’ll do it together as newly match!
