W: Hi, Jack,(12)how’s everything going around here?
M: Oh, great.(12)I think I’ll get it all done in a few days. I’ve just finished replacing the windows in the living room. Now with these larger windows, the room looks much brighter.
W: Yeah. And you also have a better view of your garden.
M: Absolutely.
W: Jack, what are these speakers in the ceiling for? I’ve noticed there’s even one in the hallway.
M: Oh, they are part of our music system. I’ve installed speakers in every room, all connected to the stereo system in the living room. That way, we can listen to the high-quality music everywhere in the house.
W: That sounds great. I’m impressed.
M:(13)You know both my wife and I love music. And I’d like to have some background music playing when I’m working out in the gym or taking a shower in the bathroom.
W: A gym? You mean you have a gym in the house?
M: Sure.(14)I’ve turned the basement into a home gym and I’ve bought some exercise equipment, but they haven’t arrived yet.
W: I see.
M: And this door here leads to the bathroom. See?
W: Hey, the gym, the music, Jack, you’re going to spoil yourself.
M: Well, you know after a busy week, you really want to relax.
W: You bet. By the way, have you done anything to the storeroom?
M: Yes.(15)I’ve made it into a multi-functional room that can also serve as my home office. You know I work at home a lot these days.
W: Jack, you’re amazing. You must be the handiest man in town.
M: Thank you.
