【C】A little girl made a difference in the world. She is Katherine.In 2006,when she was five, she saw a video about Africa on TV. Itshowed a kid would be killed by malaria(瘧疾) every 30 seconds.She asked her mom why there was malaria in Africa and why thepeople there didn’t use mosquito(蚊子) nets to protectthemselves. She was told they didn’t have money to buy one. She decided to help the kids. She sold her used clothes and toys,saved the money, and bought a net to send to Africa. When sheknew a net only could help six kids, she invited her neighbors tojoin her. She also gave speeches in churches to raise money.However, the money was still not enough. She came up with anidea to write a letter to Bill Gates. The letter said, “Dear Mr. BillGates, Without nets, the kids in Africa would die. They needmoney. But people tell me that you have all the money.” Afterreading the letter, Bill Gates donated $3,000,000 and helped havea video shot(拍攝) to raise more money. So far, Katherine hassaved two million lives. Now a place in Africa is called “KatherineNet Village” because the kids in that village write “Katherine” onthe nets to show their thanks to her.
