    A man is going to the house of a rich man. He sees a box of good apples by the road. He says," I don't want them, because the rich man will give me a lot of good food." Then he takes the apples and throws them into the dustbin (垃圾桶).

    He comes to a river. The water in the river is very deep and he can't get across (穿过) it. He says to himself, "I can't go to the rich m an' s house today." So he goes home.

    He has nothing to eat the day. He is very hungry, so he comes to the apples.

    Don't throw good things away, you may be glad to have them sometimes.
