There is a small shop about 200 meters from where I live that sells meat and other basic necessities. About 10 years ago, there was a beggar who would go into the shop every day and ask the owner for a        . The owner,       he would love to help, simply didn't have any jobs available, so he kept       the man's request.
This situation continued         for a few months, until the owner         to give the homeless man a job which        sweeping outside the shop. Every single day from 5 am, the homeless man was there doing the very        he could for the        , and it did earn him some pennies.        , the owner saw how good a job the man was doing and gave him a job working        a cashier(出纳、收银员). He was watched closely to make sure that he didn't        any of the money received from the sales. He was still homeless,       . The homeless man did a/an        job as a cashier for over 2 years, and did such a good job that he was asked to         the finances(财政、金融) for the whole shop.
Two years later, the owner        . In his will, he only had one         , to give the whole shop to the "homeless" man. Now, I could walk into that shop and see him working as hard as      , with his own business that is still       and active 10 years after getting his job as a sweeper.
