I know a story about “A Little Knowledge Is A Dangerous Thing”. It is about my younger brother. He is only five years old. He has little knowledge of swimming. I am a good swimmer. When I went swimming in the pond he also followed me. He looked at everything I did because he wanted to swim alone. Then, one day when I went to my friend’s home, my mother was in the kitchen, my younger brother went to the pond all alone for swimming. When he got down into the water he was almost drowned. At that time my father saw it and rescued him. Through this experience, my younger brother learned that “A Little Knowledge Is A Dangerous Thing”.
