Penny was a five-year-old girl. One day when she and her mother were in a department store, Penny saw a plastic pearl necklace (珍珠项链). What a beautiful necklace! She wanted it very much, so she begged（乞求）her mother to buy it for her. The mother said, “Well, I can buy you the necklace, but when we get home, we should discuss what you can do to pay for it. Can we do that?” Penny agreed with much happiness, and she got the necklace.
How much Penny loved the necklace! She wore it everywhere and every minute. Penny also did part - time jobs to make pocket money. She worked very hard. Soon she succeeded in paying off the price for the necklace.
Penny’s daddy knew how she tried her best to get the necklace. He also knew how much Penny cared about it. One night, he asked Penny if she loved him. “Sure, Daddy.” the little girl said. “Then how about giving me your necklace?” “Oh, no, Daddy! Not my necklace!” Penny cried. “Oh, dear, it’s fine.” her father gave her a kiss.
Several days later, Penny went to her daddy, with her lips(嘴唇) trembling(颤抖). “Here, Daddy. I love you.” She held out her hand. Inside it was the plastic pearl necklace that she loved so much.
When he saw this, Penny’s father smiled with surprise. He then pulled a cute box out of his pocket. Inside the box was a real and colourful pearl necklace, which was waiting for Penny for so long.
