Three were in wheelchairs, one was nearly blind and two walked with difficulty, and another two 3 a lot from Cerebral palsy (脑瘫). Matthew was among them. His hands, arms, legs, and even his voice were all distorted (扭曲) from the disease. To speak, Matthew had the help of a 4 . Slowly, and with determination, he would 5 with distorted hands, letter by letter, what he wanted to say. Yet he was always bright and cheerful and loved to 6 everything his classmates were doing, both in the boat and in the classroom. They learnt fast and enjoyed every minute of the 7 .

If only the rest of the world were able to learn to afford care, respect and help to someone less 20 than themselves, violence and intolerance (不宽容) would possibly be gone. | ||||
