[Q]: M: Good for you. Tell me about the house! W: It doesn't look good outside. but it is lovely inside. M: How nice! How many bedrooms does it have? W: Well, it has three bedrooms, two bathrooms, one big sitting room and a modern kitchen. M: Then your two boys don't need to share a room. They are happy with it? W: Yeah, they can have their own rooms. What interests me most is the small garden before the house. You know I love gardening so much. What was said before this conversation?

[A]: W: Can you believe that we've finally found a house?

[Q]: M: Hello, Susan, this is Jim. I'm calling from the bus stop at Pine Street. I've been searching for your house for about thirty minutes now, but I can't find it. I forgot to bring the map you gave me. W: OK. Wait right where you are, I'll come and get you. M: That's not necessary. If you tell me the direction once again, I'll probably be all right this time. W: OK. Can you see a bank on the corner? M: Yes, there's one across the street. W: Well, cross the street and walk past the shoe shop. My house is the seventh house from the corner on your right. M: OK. Thanks. I'm sure I'll be able to find it this time. What was said before this conversation?

[A]: W: Hello.

[Q]: W: I am the manager, Sir. How can I help you? M: Oh, really? It's this radio. It doesn't work. W: Mm... did you buy it here? M: What do you mean? Of course I bought it here. Look, you switch it on and nothing happens. W: Could I see your receipt? M: Receipt? I haven't got one. W: Oh, you should have got a receipt when you bought it. M: I perhaps did. I must have thrown it away. W: Ah, well, have you got any other proof of purchase, the guarantee, for example? M: No. It must have been in the box. I threw that away, too. W: Oh, dear. You really ought to have kept it. We need to know the exact date of purchase. M: What? I only bought it yesterday! That young man over there served me. Oh, I paid by cheque. I've got the cheque stub. W: That's all right then. Did you check the radio before you left the shop? M: Check it? No, it was in the box. I hoped it would work. It wasn't a cheap radio. It's a good make. W: You should have checked it. M: Come on! Do not tell me what I should have done, and do something! Either give me my money back or give me another raido. W: There's no need to get aggressive, Sir. Let me look at it... mm... you see this little switch on the back? M: Yes? W: It's on "main", and it should be on "battery". You really should have read the instructions. M: Oh!

[A]: M: Good morning, Miss. I'd like to speak to the manager.

[Q]: M: Not at all. Go ahead. W: What is the purpose of your visit to the States? M: I'm going to attend a conference on air pollution. W: When and where is this conference being held? M: It's being held in the first two weeks of February at the University of Stanford in California. W: Who will pay your expenses? M: The University of Stanford. Here is the official letter of invitation. W: I see. Fine. When do you want to go? M: I'd like to leave in mid-January if my passport is ready by then. W: That shouldn't be difficult. Why don't you phone me about January 10th? I should be able to give you an answer then. M: Thank you. What was said before this conversation?
