"Make-A-Wish" is one of the world's most well-known charities(慈善机构) . It makes wishes come true for children who have serious illnesses. It gives them hope and joy and helps them forget about their health problems and have fun.
It all started in 1980 in Phoenix, Arizona. Christopher was a 7-year-old boy who was very sick. He always dreamed of becoming a police officer. Tommy Austin and Ron Cox, two police officers, made his wish come true. They gave Christopher a tour of the city in a police helicopter(直升飞机) and made a real police uniform(制服) for him.
There are four kinds of wishes children usually have:
I wish to go. Children usually want to travel or go to a concert, a game or a park.
I wish to meet. Children sometimes want to meet their favourite actors, singers or players.
I wish to be. Some children wish to become actors, singers or police officers.
I wish to have. They often want to have a computer, a game, a bike or many other things.
Let's hope more wishes will come true in the future. People who work in the charity always try for the best. Almost 25 ,000 volunteers(志愿者) help, work or give money. Will you be one of them?
