     A man from a big city with a new cart (马车) and a beautiful pair of horses was driving along a

country road . He did not give much attention to where he was going. Very soon he knew he lost his

way, but he kept on driving hoping he would meet someone or find his way back.

     It was a long way. For many hours he kept on driving. When it was almost dark he saw a farmer

who was working in a field. He stopped and shouted, "Hello, farmer!" "Hello, yourself!" the farmer

answered, still working.
