The school was across the street from our home and I would often watch the kids as they played on the playground. She seemed so small as she pushed her way     36     the crowd of boys on the playground. She    37   from them all. I began to notice her at other times, basketball in hand, playing    38  . She would practice dribbling(运球)and shooting over and over again, sometimes until   39  . One day I asked her   40   she practiced so much. She looked   41   in my eyes and without a moment of hesitation she said, “ I want to go to college. The only way I can   42   is to get a scholarship. I am going to play college basketball. I want to be the best. My daddy told me if the dream is   43   enough, the facts don’t count.”
Well, I had to give in to her—she was   44  . One day, I saw her sitting in the grass, head   45   in her arms. I walked toward her and   46   asked what was the matter. “Oh, nothing,” came a soft reply, “ I am just too short.” The coach told her that at her height she would probably   47   get to play for a top ranked team,    48   offered a scholarship. So she   49   stop dreaming about college.
She was   50   and I sensed her disappointment. I asked her if she had talked to her dad about it yet. She told me that her father said those coaches were wrong. They just did not   51   the power of the dream. He told her   52   she really wanted to pay for a good college, if she truly wanted a scholarship,   53   could stop her except one thing---her own attitude. He told her again, “If the dream is big enough, the facts don’t count.”
The next year, as she and her team went to the Northern California Championship game, she was   54   by a college recruiter(招聘人员). She was indeed offered a scholarship. She was going to get the college education that she had   55   and worked for all those years.
