Katherine Com male is an 11-year-old girl from Pennsylvania. At the age of five she began raising money to buy nets for children in Africa to help stop the spread of malaria(疟疾).
When she was five, Katherine learnt about malaria in Africa. She learnt that every 30 seconds a child died from this disease. She, also learnt that people wouldn’t get that disease if they had enough bed nets. “I was really sad to learn that a child died every half a minute because of malaria.” Says Katherine, “I wanted to send nets right away, so that’s what I did.”
Five-year-old Katherine made presentations at churches and schools. She told students and others how important bed nets were for Africans. After people heard the presentations, many of them donated money. Katherine sent the money to NBN. NBN is an organization that sends bed nets to Africa.
Besides_, every holiday Katherine makes something called “ net gift certificate” with the help of her friends and brothers. On each l0-dollar certificate there is a message. It explains that a bed net would be sent to Africa. When more certificate orders come, Katherine gets help from students in her school.
Katherine has helped to raise $200,000 for NBN. “It makes me proud to help African children. I won^’t stop working until everyone in Africa has a bed net.” says Katherine.
