Michael Platte, a 12-year-old boy, is from the USA. He likes making cupcakes (纸杯蛋糕). His grandma is his teacher. Now he's good at making all kinds of cupcakes. He always makes cupcakes on Sunday afternoon and takes some to his classmates the next morning. They say the cupcakes are nice.

One day, Michael sees a boy standing in front of(在……前面) a cake store for a long time. He is from a shelter(收容所). He stands there and watches a big cake. The boy loves it, but he doesn't have money. Michael really wants to help the homeless children like the boy. Then with his family's help, Michael has a small cupcake store - Michael's Desserts(甜点). When Michael sells one cupcake, he gives $ 0. 5 to the shelter. And every week he gives about $ 15 to it. It's not much money, but his small act of kindness (善举) can help those children.
