W: Have a seat, Mr. Smith. Now, what’s the problem?
M: Well, as I told you on the phone, (19)I’m having a lot of trouble with my landlord.
W: That’s right. But can you explain in detail? What sort of trouble?
M: Well, when I moved in six months ago, he said he was going to fix up two or three things that needed doing.
W: What kind of things exactly?
M: Well, for example, there was no ventilation (通风设备) in the kitchen and the hot wetter system wasn’t working properly.
W: And did he say he’d have them attended to?
M: Yes, that’s right. (20)He promised to have them done. But now six months have gone by, yet nothing has been done.
W: Urn... so he’s broken his promise.
M: Yes, and not only that. Now that the lease has run out, (21)he wants to increase the rent by $ 10 a week!
W: Well, (21)he can’t do that without your agreement, you know.
M: Yes, I know that, but the trouble is that he will evict me if I don’t agree.
W: Yes, that’s true. He can do that. However, eviction is easier said than done. Don’t worry!
M: You mean it could be difficult for him?
W: Yes, he can’t just throw you out on the street. He has to give you reasonable notice in advance, usually a month.
M: So that means I can stay there at least for a month? That makes things easier.
