[EX Q]: 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 .

[EX Q]: Person1: Hey , Joe ! Where have you been these past few days ?
Person2:I ' Ve been busy with a first aid course that I started about a week ago at the Red Cross .
Person1: Cool ! I ' Ve always wanted to do something like that ! Have you learned anything useful ?
Person2:For sure ! I mean we ' Ve learned how to apply pressure to stop bleeding , how to check for a pulse , and even how to apply CPR !
Person1: Have you treated any real emergencies ?
Person2:Well , they took us along with some paramedics.There was this guy who fell off his motorcycle and suffered a concussion as well as a couple of compound fractures . His wounds were pretty serious so they had to rush him to the hospital . It was intense !
Person1: I can imagine ! I tend to faint when I see blood , so I think I won ' t be taking up a course like that anytime soon !
