Anne: I can’t stand this heat. I can’t give my attention to 41 (learn) for the mid-term exam. I guess I will have to go to the library this afternoon.
Mary: The dormitory does not have an air conditioner. I can’t study there, 42 . My roommate and I are thinking about moving out to an apartment 43 has an air conditioner.
Anne: Oh, I 44 (think) about moving for a long time. But if I live in an apartment, I will have to pay a lot of money for electricity. Do you know an air conditioner is 45 (expensive) today than it was 10 years ago? On the other hand, electricity prices have risen sharply.
Mary: I don’t know that. 46 do we have to pay for electricity?
Anne: Five years ago it was 47 (possibility) to run an air conditioner 24 hours a day for just $20 a month. Today running 48 same air conditioner costs more than $40 a month.
Mary: Oh, no. That’s 49 (extreme) expensive and I can’t afford it. Well I guess I will tell my roommate we will go to the library. If 50 doesn’t work out, we will sweat all summer.
