     I was doing some last-minute Christmas shopping in a toy store. A nicely dressed little girl was   1   the
teddy bears (泰迪熊) beside her father   2   she saw a little boy walk in and stop in front of the Pokémon toys.
His jacket was obviously too small. He had money in his hand.   3  , it looked no more than five dollars at most.
He was with his father as well, and   4   picking up the Pokémon video games. Each time he showed one to his
father, his father   5   his head, "No".
     Rather   6   , the boy gave up the video games and chose a book of stickers   7  . After they walked away,
the little girl ran over to the Pokémon video games. She excitedly picked up one   8   on top of the others, and
raced down toward the check-out. I picked up my purchases and   9   the girl and her father.
     Then, much to the little girl's   10   , the little boy and his father got in line   11   her and me. After the
video was paid for and bagged, the little girl   12   it back to the cashier (收银员) and   13   something to her.
The cashier smiled and put the   14   under the counter (柜台). I was putting things in my bag when the little
boy came up to the cashier. The cashier said,"   15   , you're my hundredth customer today, and you win a
prize!" and she handed the boy the Pokémon game. The boy could only   16   in disbelief. It was, he said,
   17   what he had wanted! The little girl and her father had been standing at the doorway, and I saw the
biggest and   18   smile on that little girl I have ever seen in my life.
     I suddenly understood that the world is not   19   into the strong who care and the   20   who are cared
for. We must each in turn care and be cared.
