     Once upon a time there was a writer living by the sea. He had a habit of walking along the

beach before he began his work.

     One day he was walking along the beach, and he saw someone moving like a dancer. He

smiled and began to walk faster toward the men. As he got closer, he saw that it was a young

man and the young man wasn't dancing. He was bending down to the send, picking something

up and very gently throwing it into the.sea.

     As he got closer, the writer called out: "Good morning! What are you doing?"

     The young man stopped, looked up, and said: "Throwing starfish( 海星) into the sea. "

     "Why are you doing that?"

     "The sun is up, and the tide( 潮汐)is going out. And if I don't throw them into the sea, they

will die."

     "But, young man, don't you think that there are so long a beach here, and starfish all on the

beach? You can't make difference. "

     The young man listened politely then bent down, picked up another starfish, threw it into the

sea and said: "It made a difference for that one."
