“Jamila , I just found one dollar sitting on the coffee table ,” said Mrs . Johnson . “Is that your money ?”

Jamila looked up from the book she was reading . “Oops , it’s mine . I emptied my jacket pockets before I left for basketball practice yesterday . I was running late , so I didn’t have time to take it up to my room .” Jamila placed it quickly in the back of  her book and went back to reading .

“Jamila , you just put that money into the back of your book . I’m quite sure that you’re not going to be able to find it when you need it .” her mother said . “You see , some of your money is in the pencil case on your desk . Some is in the glove hanging behind the door . I think you might also have a few dollars in your bag . You are such a careless girl .”

“Mom . I’m too busy to take care of my money .”

Mrs . Johnson smiled , “It looks like it’s time for you to get your own bank account (账户).”

“My own bank account ? Is it necessary ? Kids know little about it .” Jamila replied .

The next day , Mrs.Johnson took Jamila to a bank and opened an account for her . The banking manger explained how the money in the account would increase . “The longer the money stays in the account , the more it will earn(获利) ,” he added .
