M: Have you ever read Harry Potter? W: I'm afraid I haven't. M: What a pity! You really should. It's very interesting, you know. I have a copy here. If you like, I'll lend it to you. 2. M: Look! Jack has got the ball. Oh, go on Jack. W: That Oxford full back is trying to stop him. 3. W: Alan, have you got a meeting in Edinburgh? M: Yes, I'm going to see some important people. Why? W: I'm going to visit Glasgow on Wednesday and it's quite near Edinburgh. M: Ah...I'm going to drive there tomorrow, so you can go with me. 4. M: Did you watch the football match on TV yesterday evening? W: No, I didn't. I had dinner with a friend and didn't go back home until 8 o'clock. 5. M: Shall we watch TV tonight? W: All right. What's on tonight? M: A pop show on Channel Six is at 7:30. Then at 8:20 there is a western. 6. M: Hey, Susan. You are good at remember things, aren't you? W: Yeah, I guess so. Why? M: I'm always forgetting things. Last week I went to the bank for some money, and I forgot to take it out of the machine. When I remembered and went back, the money was gone. Besides, I couldn't remember where I parked my car. W: That's pretty bad. M: Can you give me some advice on ways to improve my memory? W: Not really. You'd better let me drive you to the bank next time. 7. M: Can I help you? W: Yes, I want to flight to Chicago on Wednesday the seventh and return on Friday the ninth. How much is the ticket? M: Tickets are cheaper if you stay over Saturday night. W: Thanks, but I have already arranged some business here that Friday. So I have to pay the extra cost. M: What time of day would you prefer, morning or afternoon? W: Morning, because I have to be there by early evening. Is there a meal? M: Yes, they will be serving breakfast, and you will also see a film. W: Sounds good. But what's the total cost? M: Eight hundred and fifty dollars round trip. W: That's more than I expected. 8. M: Hi, Ann. How's your new flat? W: Well, that's what I'm telling you about. You see, I've decided to look for a new place. M: Why? I thought you liked it. W: Oh, I do. But the distance is just killing me. Do you think you could help? M: OK. So, what kind of place are you looking for? W: Well, I'd to share a flat with one or two roommates within walking distance to school. M: How much do you want to spend a month? W: Uh, under ￡200, and I'd like a flat with furniture in it. M: Well, I know there're many flats around the corner that seem to have a few flats left. I'll draw by there. W: Thanks a lot. 9. M: Help! Yeah, uh, it was really strange, I mean. W: Calm down, sir. Tell me what exactly happened. M: Well, I was driving home from a party about three hours ago, so it was about 2:00 o'clock a.m. , when I saw this bright light overhead. W: OK, and then what happened? M: It was out of this world. I stopped to watch the light when it disappeared behind a hill about a kilometer ahead of me. W: Then what? M: Well, I got back in my car and started driving towards where the strange machine landed. W: Perhaps you only saw the light of an airplane, or the headlights of a car coming closer. Things like that happen, you know. M: I kept driving for about 5 minutes when suddenly, a huge animal jumped out in front of my car. W: Oh, yeah. Then what? M: Then, the animal picked the front of my car and said "Get out of the car. I'm taking you to my master." Something like that. W: Wow!An animal can speak English! Come on! M: Then, the animal opened the car door, carried me on his shoulder to this round flying machine, and well... W: OK, that's enough. 10. Ladies and gentleman, thank you very much. I won't take much of your time, thank you. Jayal motors has decided to move into the export business. Now, we weren't sure till late yesterday afternoon about this decision. I didn't tell you anything before that because we had to make research on the market first. Now then, I went to Australia to see if I could get us an export market. Two days ago we got word that we had got our first export order: 100 bikes, delivery in two months. Now you all know the situation on the home market. We're a small company. The big companies are moving into the provinces and putting small firms like us out of business. We have got to expand, and we can't afford to lose this chance. We can't afford to make any mistakes.
