Kate's dream of helping poor people started when she was visiting her father, who worked for the homeless.

"I never knew that there were so many people in the world who didn't have home or food before,"said Kate, a university student. "I got to know that there was something important I had to do."

At the age of 14, Kate started to raise money with her friends to build a playground. "It took us two years,"she said."We did it little by little. We hoped our efforts(努力) could help make a difference."

In 2016, when Kate was 16, she visited some places in Africa. She saw many people going hungry and families living in houses made of cardboard(硬纸板)."The rooms were smaller than my bedroom, but there were eight people living in each one,"Kate said."We also found some dirty rivers. Those people got drinking water from them."The next year, Kate set up a club with her friends. It helped poor people in Africa.

Providing clean drinking water, food and clothes for the people living in poor areas is now an importanttask for Kate's club. "This girl is changing some people's lives, and she is also changing the world,"said Kate's teacher.
