early in this year．Then I waited for the results．By mid—July，                                 
I still hadn’t received an answer．There are only two weeks                                      
left，but I gave up．Then，on August l，they called and said I                                   
had been chosen．I was shocked．“Please give her a few minutes                                 
to think about it” I said．Then I called my mom to help me buy                                  
a plane ticket．I was so exciting．I would be in Beijing the next day !                              
My task was to stand at the gate of a stadium and offered help

worth it. Besides, I also got free ticket to one of the football matches．
