     Sam “Fingers” had been in trouble all his life.He'd started stealing things when he was only a kid(小孩).He used to walk through the street market near his home and “pick up” a few things-a pine apple or a hairbrush perhaps.But things got worse as Sam got older.By the time he was twenty-five he was spending a lot of time stealing-and then he got caught(被抓).While he was in prison he decided that he'd never steal

again.He really had to stop.

     On his first day out of prison,Sam went for a walk along the High Street.It was so nice to walk along in the crowds and look at the shops.Oh,the shops!

     "I'll just go into this jeweller's and have a look around,” Sam said to himself,“there is nothing to worry

about.No more stealing for me.”Then Sam saw the diamond ring.He'd always wanted to give one to his

girlfriend.And nobody was looking.In a minute the ring was in his pocket and Sam was walking out of the

shop.But as he went towards the door he felt a hand on his shoulder.

     "I saw you put that ring in your pocket.” said the manager.“I shall have to call the police.”

     "I will pay for it.Yes,I'll pay for it”.said Sam.

      With a smile,the manager handed him the bill:500!

      “Er,um,well^_…”said Sam,“ I really didn't want to spend that much.Would you please show me

something a little cheaper?”
