Once a small boy lived on a 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 .a break and climb up on the fence(篱笆)along the side of the farm. He could see a house with 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 1 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 know how wrong he was. The house was much farther than he had expected. As he went near the house, he saw no golden windows but instead a place in bad need of a painting. A small girl very close to his age came out of the poor house and stood by the broken fence. He asked her if she had seen the house with the golden windows. The girl said, “Sure, I know.” and invited him to sit on the porch (门廊).As he sat there, he looked back from where he just came. There he saw the sunset turned the windows of his house to gold! Now he understood that everyone had his own house with golden windows.
