听力原文： We're very happy to we Icome you to the historic city of Brantford and to have you join us on one of our tours today. The entire trip will take most of the afternoon. We'll start with a fairly short tour of the city center area, driving by the main landmarks there and that will take us about half an hour or so. You'll see the city's distinctive architecture, dating back to the late eighteenth century. And we'll stop briefly at the government buildings before leaving the city center. Then, after we leave the city, we'll cross one of the oldest suspension bridges in the world. We'll proceed to the National Museum of Art, and then to our highly regarded weather observatory. If you have any questions, feel free to address them to me at any time. Now, let's begin our tour. What does the speaker say about Brantford?
