A man went to the house of a rich man. He saw a bag of apples by the roadside. He thought, “I don’t want to eat those apples, because the rich man will give me a lot of good food.” Then he took the apples and threw (丢掉) them away into the dust(垃圾堆).
He came to a river. The water in the river was very deep(深) and he couldn’t go across the river. He waited for some time and then said, “I can’t go to the rich man’s house today because I can’t cross the river.” So he began to go home.
He had nothing to eat that day. He was very hungry when he came to the apples. He was glad to take them out of the dust.
Don’t throw good things away, you may be glad to have them sometimes.
