4.I'll never forget the night in 1946when disaster and challenge visited our home.My brother,George,came home from football practice and his temperature sharply fell.After an examination the doctor informed us it was polio(小儿麻痹症). The doctor felt it was his duty to inform George of the horrible truth that he couldn't walk as others any more.
George had always expected himself to be a championship wrester for his senior year,after just missing it the season before while he was a junior.Mom and dad taught us that we should never let a damaging thought come into our mind and break up our dreams.
The next day George practiced walking and refused any assistance or even a walking stick that was given tohim.Six months later,he stepped out on the mat as captain of the wrestling team.No one had ever been known to recover so quickly or so completely from this disease.
The next year after being named to start for Missouri Valley College,George caught mononucleosis(单核细胞增多症).The family was sitting in George's room at the hospital watching the game on TV,when the announcer said,"And George Schlatter makes the first catch of the game"
Shocked,we all looked at the bed to make sure George was still there.Then we realized what had happened.My brother Bob who had made the starting line-up,had worn George's number so George could spend the afternoon hearing himself catching six passes.
George spent the next 3falls season in the hospital.Following each challenge,George came back stronger of his own ability to overcome any obstacle.He had literally been through the furnace(火炉)and come out of It with a soul as strong as steel and he used it to strengthen and entertain a ntion.
