Last Sunday, Peter went swimming in a lake. The weather was fine. There were many people by the lake. A little boy was playing by the lake, too. Suddenly, the boy fell into the lake. He was too little to swim. Then a strong man jumped into the lake and swam to that boy. He brought the boy back to the bank (岸边). The boy's parents were very grateful(感激的 ) to the strong man.
