"Make-A-Wish” is one of the world's most well-known charities(慈善机构) . It makes wishes come true for childrenwho 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 ofbecoming a police officer. Tommy Austin and Ron Cox, two police officers, made his wish come true. They gaveChristopher a tour of the city in a police helicopter(直升飞机)and made a real police uniform(制服) for him.
