完形填空
I used to live selfishly, I should admit. But one moment changed me.
I was on my lunch break and had  41  the office to get something to eat . On the way, I  42 a busker (街头艺人),with a hat in front of him. I had some  43 in my pocket, but I would not give them to him, thinking to myself he would  44  use the money to feed his addiction to drugs or alcohol. He  45  like that type---young and ragged.  46  what was I going to spend the money on ? Only to feed my addiction to Coca-Cola or chocolate! I then  47  I had no right to place myself above  48  just because he was busking.
I  49  and dropped all the coins into his  50 , and he smiled at me. I watched for a while. As  51  as it sounds, I expected something more to come from that moment—a feeling of  52  or satisfaction, for example. But nothing happened.  53 , I walked off. “It proved to be a waste of  54  ,” I thought.
On my way home at the end of the  55 , I saw the busker again and he was _56 . I watched him pick up the hat and walk  57 a cafe counter. There he poured the  58  contents into a tin collecting  59  an earthquake fund-raising (募捐) event. He was busking for charity!
Now I donate any  60  I have to charity tins and enjoy the feeling of giving.
