       A man was exploring(探测)some caves on the beach.ln one of them he found a bag with many

clay(泥)balls. It seemed that someone had made them and had left them there. They interested the

man very much,so he took the bag out of the cave with him.

       As he was walking down the beach,he threw one clay ball at a time into the sea as far as he could.

       He didn't think much of it until he dropped one of the balls. The clay ball broke,and a beautiful,

precious stone came out of it.Excited,the man started breaking the other clay balls. He found that they

all had similar treasure in them. He found treasure that is worth thousands of dollars in the 20 left clay

balls.

       He regretted that he had thrown away about 50 0r 60 of the clay balls into the sea. He could have

had a lot more money.

       This is just like what happens in life. We look at people,maybe even ourselves,only from the outside. The outside doesn't look beautiful,so we pay no attention to them and only envy(羡慕)people who are

beautiful or famous. We don't notice that we may have missed the treasure inside those people.
