     St. Martin's Day is a holiday in Holland. St. Martin was a man who did kind things for many people

in need. One cold winter day he was walking home. He wore a coat to keep warm and had a small piece of  bread to eat. Then he saw a stranger on the side of the road. The man sat on the ground and he was

hungry and had no home. St. Martin took out his knife and cut his coat in two. He gave the man half of his warm coat. Then he gave the man half of his bread.

     Nancy was a schoolgirl in Holland. One St. Martin's Day, she rode her bicycle with her classmates

after school. When she got home, she said goodbye to her classmates and went into her yard. As she

homeless cat. "That old cat keeps .scaring me!" she complained as she walked into the room. "It won't

hurt you," said her father.

     She was angry about the cat but she could not be unhappy for long. It was St. Martin's Day. "Who

was St. Martin anyway?" Nancy asked. Father told her the story of St. Martin. Nancy was touched

(惑动) by the story. She put a piece of bread in her bag and went into the yard.

     Nancy heard the noise again. "You wait a minute!" she called as she ran after the cat. She caught it
