Carly Zalenski's eyes filled with tears.The 14-year-old and her family came from Canton，Ohio.As they approached the village，hundreds of cheering schoolchildren lined the entrance to the school Carly had raised money for.
Carly started helping others at eight，handing out Thanksgiving baskets at church to families in need.It was a snowy day，and she saw many people without warm coats.The next November，she went door to door asking for used coats，hats，gloves and scarves，then handed them out with the baskets.
But Carly wanted to do more.She remembered her grandmother's Rotary Club(扶轮社)had，years earlier，raised money to build a school in Vietnam.That was what she now wanted to do.
At 12，she began to raise money for Vietnamese children with a PowerPoint presentation.“The kids in rural Vietnam can't go to school.I want to give them a place to make their lives better.”She told a room of 200 club members.That summer.Carly set off with her family across Ohio，visiting three or four Rotary Clubs a week.“We traveled like crazy people to all these meetings，”recalls her mother，Kris.
The first few sessions yielded no donations.But one night，Carly and her dad，Fred，pulled up to a building in Minerva，Ohio.Carrying a laptop，a projector(幻灯机)and a screen，they walked into a bar where 15 people were sitting around a long table.There was dead silence after Carly finished her presentation.Fred thought that it was never going to work.Then someone made a motion：“Let's give this girl at a check right now.”Minutes later，Carly walked out with her first donation：D|S500.
Not everyone was wild about the idea of helping Vietnam.“Why should we help a Communist country？”asked one veteran(老兵)．Carly replied simply，“They're kids.And I'm just a kid who wants to help out.”
As word spread，individual donors sent checks for as little as D|S5.A restaurant chain contributedD|S1,000.Carly's coach organized a tournament that netted D|S4,000.A Bible camp bought 500 backpacks for the children.In total，Carly raisedD|S50,000，which was matched by the Vietnam Children's Fund.At the dedication ceremony，the school principal was impressed with the_ninth_grader.“How wonderful，”he said，“that a girl at her age wants to change the lives of kids so far away.”
