Person1: Bob , you're so lucky that you've come at the right time-the 2005 International Tourism Festival is around the corner .
Person2:We've heard about that festival before . It would be quite helpful if you could give us some highlights of the festival .
Person1: My pleasure . Well , the festival is going to start on the third Saturday of October , and covers over one hundred diverse programs in one month .
Person2:What do you think we can see during the festival ?
Person1: I don't know what to suggest . There're so many attractions , and they all sound interesting . One exciting program might be the Ten Thousand People Cycling round the Town . You can choose from the five routes that lead to different destinations .
Person2:I'd like to take the one that goes to the Wild Animal Park .
Person1: Then you can take Route No . 5 . Next I would suggest the International Dragon Boat Race where you can watch Lion Dance , Dragon Boat racing , and many other water shows .
Person2:Wow , must be interesting to watch dragon boats compete a-gainst one another on the city river .
