It was Mabel's birthday one day. Mrs. Black had not enough money to buy a birthday cake for her. When she was walking past a shop, she spent all her money on some plums(李子). She put them on a plate and began to cook. Peter, her five-year-old son, saw them. He never ate any plums and wanted to taste one. He looked around and there was nobody except himself. He quickly ate one and left.
That evening Mrs. Black found a plum missing. She asked,“Who ate the plum?”
Every child answered,“It's not me.”
“I'm afraid you swallowed(吞) the stone(核),”said the mother,“then you'll be ill.”
“Don't worry about it, Mummy,” Peter said happily. “I threw the stone out of the window!”
