If I have the honor to be chose to work for the 29th Olympic Games, I will at first improve my English so that I can talk easily about foreign visitors. Second, I will learn more about history of the Olympics as much as the 2008 Olympic Games. Third, since I was familiar with Beijing, I can help visitors find their ways in the city. Finally, I should be able to tell visitors about our history or culture and show them their great achievements. In short, I will do my best to help making the Games a success.
