    Once a small boy lived on the farm which seemed so far away from everywhere.

    He needed to get up before sunrise every morning to help his father on the farm. During sunrise he would take

a break and climb up on the fence along the side of the farm. He could see a house with a golden windows. "If

they could afford golden windows, then there must be other nice things inside the house." He imagined how

great it would be to live there. Then he promised himself, "Some day I will go there and see this wonderful

place". 

    One morning his father would go to the town and told him to stay at home for a rest. Knowing that this was

his chance, he took a sandwich and headed across the field towards the house with the golden windows.

    As the afternoon went on, he began to realize how wrong he was. The house was much father than he had

expected. As he went near the house, he saw no golden widows but instead a place in bad need of painting. A

small girl very close to his age came out of the poor house and stood be the broken fence. He asked her if she

had seen the house with the golden windows. The girl said, "Sure, I know," and invited her to sit on the porch

(门廊). As he sat there, he looked back from where he just came. There he saw the sunset (夕阳) turned the

windows of his house to gold! Now he understood that everyone had his own house with golden windows.
