What country/city did Kate visit? What information helps you to understand it? (reading/listening for detail)
Kate: Oh Jess, it was a marvellous trip. Everything was perfect. I am so happy.
Jess: Are you? But, what makes you so happy? You know a Iot about the country you visited. Did you like their English?
Kate: It sounds strange, but I didnt mind it. I understood them... most of the time. But they looked at me as if I were a representative of an aristocratic family or the British ambassador (засол).
Jess: Thats really surprising. Is that all, Lady Kate?
Kate: Stop it. Cant you see that I am full of impressions? Know anything about their capital?
Jess: Yes, I do know about it. I know that their lawmakers moved there in 1800.
Kate: Well, have you ever heard about the mysterious echo in the National Statuary Hall?
Jess: Echo? In a hall? Youre kidding (ты разыгрываешь меня).
Kate: No! There were times when Representatives met there to discuss political problems. So, Mr John Quincy Adams desk was just on the place where he could hear whispered (произносимые шепотом) discussions of the opposing party on the far side of the room.
Jess: You must be joking.
Kate: No! Just fancy that (только представь для себя)! He surprised everyone when he seemed to guess what the other side was going to do before they did it.
Jess: How rotten (какая низость)!
Kate: Yes1 I agree. I saw so many interesting things: I saw the Senate and the House of Representatives in action while they were in session. It was terrific.
Jess: Im sure it was.
Kate: Oh Jess, you must see it to understand how great it was.
