Tom is a naughty boy.In this summer holiday,she likes to catch the frogs from pond.And on this Sunday,he goes to the pond again and catch many frogs.He's always happy for doing that.One day,he stays at home and listens to the radio.The radio says"Protecting frogs is very important.Frogs can bring many profits to people.We must protect them and do not hurt them".Tom feels strange and he reads some passages about protecting frogs.Tom is ashamed about that.He comes to the pond.What will he do?He is not for catching frogs.He is "sprinkling" for the frogs.He wants to do something good for animals from then on.
