4 阅读理解。 All of my childhood and early adult life, my mom weighed over 220 pounds (one pound = 0.454 kilograms). I could feel the pain that my mom experienced with her fatness. I was never uncomfortable about my mother, but I think she was uncomfortable about herself, and that feeling was painful for all of us. And she began to lose weight. After more than twenty years of battling obesity(肥胖), my mother completed a forceful eighteen-month diet that left her ninety pounds lighter than before. A new woman was born! At age twenty-eight, I got a new mom! For the first time, I met the woman my mother truly was, the beautiful little lady under the fatness. It wasn"t so much her new body that was the surprise, but rather her new spirit. To celebrate her new size and to devote herself to dancing again, my mother joined a "Mrs. Forty-Plus" competition, where she would have to model, give a speech and provide a dance performance. She told our family that she did not care if she won - she simply had always wanted to perform on stage. She told each one of us, "I"m not doing it to win; I"m doing it to dance!" The competition was exciting! I prayed that my mom would win, but while watching her on stage I was simply overjoyed just by her effort. To me, she had already won. She posed to perfection, her speech brought tears to everyone"s eyes, and her performance was wonderful. That night, at age fifty-three, my mother was crowned (为......加冕) "Mrs. Forty-Plus".
