     It was December 25. Marie, a 13-year-old Australian girl, was happy It was Christmas,

and Marie's mother was making a special cake. She put four small coins into the cake, and

then she baked (烤) it. The four coins were for good luck. After dinner Marie and her family

ate the cake. They found three coins in the cake and put them on the table. Where was the

fourth coin? It was missing, but Marie's mother didn't notice.

     After Christmas Marie got sick. She coughed, and she couldn't speak. After six weeks she

felt better, but she still couldn't speak. Marie's parents took her to hospital. Doctors at the

hospital looked her over, and then said, "We are sorry, but we can't help her." For 12 years Marie

didn't speak. She grew up, she got a job, and she got married. But she never spoke. One day,

when Marie was 25 years old, she got a sore throat (嗓子疼) at work. She began to cough. She

coughed up something small and black. What was it? Marie didn't know. She took it to the hospital.

A doctor at the hospital said, "This is a coin!" The doctor told Marie, "I think you can speak again.''

 Marie went to a special doctor, and soon she could talk.
