听力原文： Good morning. My name is Taylor and I will be your tour guide today. Right now, we are in the Ambassador Room of the Rawlins Building. This room is used mainly as a meeting place between high officials and foreign diplomats. Guests arrive from those big doors, while the host greets them from where you are now standing. Recent guests have included the Queen of Denmark and the Prime Minister of Canada. Notice the wonderful artwork adorning the walls. Each painting is a portrait of the original Rawlins Building designers. Let's go to the next room.
