be   1  Christmas gifts because there was not enough money in our family. I felt sad and thought, "What
would I say when the other kids asked what I had   2  ?" Just when I started to   3    that there would
no  Christmas that year, three women   4    at our house with gifts for all of us. For me they brought a
doll. I felt such a sense of   5    that I would no longer have to be embarrassed (尴尬) when I returned
to school. I wasn't   6  . Somebody had thought me important   7    to bring me a gift.  
   Years later, when I stood in the kitchen of my new house, thinking how I could try to make my   8  
Christmas in the new house special and memorable, I   9   remembered the women's visit. I decided

(孤儿) were invited at our Christmas party. For every child, we wrapped colorful packages

couldn't open their presents   15  every child had got his. Finally the   16  , which they had been so
eagerly waiting for, came as I called out, "One, two, three. Open your presents!" As the children opened
their packages, their faces beamed and their bright smiles   17  up the whole house, where The
atmosphere of   18  was so obvious, and  19 wasn't just about toys. It was a feeling - "I wasn't
forgotten", which I have been so familiar   20   that very Christmas long ago when the women came to
visit us. Being concerned matters much for any child.
