    Several years ago, 1 a cold winter morning, I was shopping alone. I tried to buy some winter socks to 2 my cold feet warm. When I went around the corner in the store, I saw a Christmas tree 3 paper angels(天使). On each angel was the name of a poor child 4 family couldn't afford to buy him/her a gift that year. Shoppers who picked an angel could buy a simple toy or gift and the store would 5 it up and send it to the child that Christmas.

    Around the tree, I saw a boy and a girl picking out several angels each. Their mother was smiling while she was watching 6. I walked up next to her and started talking with her. She told me that her children 7 this several years ago when she first explained to them what the Charity Angel tree was for. Each offered to give up one of their toys that year 8 a poor child could have one. Since then, the two have 9 money the whole year in order to buy gifts for more children. It has become a family tradition.

    When we finished talking, I smiled. I walked over m the tree, and picked out a few angels, too. I left the store, feeling 10 and love for that Christmas.
