In a far-away place, there was a village. The village was1in potatoes than anywhere else in the country. At the end of every growing season,2potatoes were dug (挖掘) out of the ground, and readied for market. In each home, men and women would3divide (分成) the potatoes into three groups, large, medium (中等) and small.
One year, there was a young man4received his share of the potatoes. As the other villagers5, he walked around the village laughing and talking.
6villagers thought he was lazy, and they worried that this man would never get7potatoes ready in time. When it was time for the villagers8to market, they were greatly surprised to find that the man's potatoes9perfectly into three groups.
After10the man how he did it, they understood he was not lazy,11very clever. He had put all his potatoes in a car（t 运货马车） and pulled it along the village's rough dirt (肮脏粗造的) road. As the cart moved up and down over the road, the potatoes moved12. The small potatoes moved to the bottom, the larger potatoes rose to the top and the medium potatoes rested13the middle.
Life14like this too. The rough roads we travel along can also15us.
