Jenny was almost five. Waiting with her mother at the checkout stand, she saw a circle of white pearls（珍珠） in a box. “Oh please, Mommy .Can I have them? Please, mommy, please!” Quickly the mother checked the back of the little box and said ,” That’s almost $2.00. If you really like them, I’ll think of some extra chores for you and in no time you can save enough money to buy them for yourself.” Then Jenny began doing more chores at home and did housework for neighbors. On her birthday, Grandma gave her another new dollar bill and she had enough money to buy the necklace.
