The gymnasium smelled of delicious food and was filled with people.The place was more lively when kids in each class of kindergarten came in and sat in chattering rows.This was the big day --- the kickoff to the St.Baldrick's event.And the kids knew what was coming.A fourth-grade teacher was about to have his head shaved.
    The St.Baldrick's Foundation provides funds for children's cancer research.Their money comes from participants offering to publicly shave their heads in exchange for donations to the fund.When the fourth-grade teacher Mr.Leckron offered to shave his blond hair for the good of the cause，many kids signed up to be shaved as well.Many community members and parents stepped forward to donate money to support the events.
    This event took place on a May afternoon.In the beginning of the after-school community shaving event，our principal stepped to the microphone and introduced the honorable guest，our town's mayor（市長）．Our mayor said the students were worth his respect because they were so sympathetic（同 情的）to those unfortunate.
    After the mayor's speech，a mother stepped to the microphone and shared the story of her son's childhood cancer.The mother said the cancer was terrible to his son，but the St Baldrick's funded research made him triumph over the challenge in the end.His story showed how the program was making a difference to real people.
    Next the barber stepped forward and gestured Mr.Leckron to the stage.But Mr.Leckron shook his head and pretended to be afraid.Everyone cheered as Mr.Leckron walked forward and took his seat.When the barber shaved a path right down the center of Mr.Leckron's head，everyone laughed.My heart pounded.I was excited at the joy that filled the gymnasium.
It stated that our little school raised over 10，000 dollars in the end.When I learned the good news of the result of the event，my eyes welled and I took great pride in my community that supported it.
