dialogue: M: How time flies! The winter holidays are coming next week. W: Yes, do you have any plans? M: Certainly. I want to go to Egypt. What about you? W: I'm afraid I can go nowhere. I failed my English exam. You know my parents are so strict with me. M: Bad luck! W: I see. Is Egypt an African country? Is it far? M: Yes, it's in Africa and quite far. But it's not only the Pyramids that I want to see but the Aswan Dam. W: You want to see? M: Of course. I'll go there by boat on the Nile. W: That'll be wonderful and interesting. How will you get there? M: By air - by flight No. CA808. My sister works on it. And then I'll be treated as a king! W: Don't be so proud. I'll be off now. I wish you a good trip. M: Oh, sorry. I didn't mean that. I don't want to hurt you...
