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 .

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 .
