Today, the little horse’s mother says to him, “You must take the grain to the mill（磨坊）.”
　　He must cross the river on his way to the mill. When the little horse is thinking how to cross the river, a squirrel（松鼠） comes over to him. The squirrel says to him, “The river is deep（深的）. My friend died yesterday.”The little horse is afraid.
　　Then he sees a cow and asks him, “Is the river deep? How can I cross the river?” The cow says to him, “No, it’s shallow（浅的）. It’s up to my knee（膝盖）.”
　　The little horse says, “But the squirrel said it was deep.” The cow says, “The squirrel is shorter than you, you can cross it.”
　　Finally, the little horse tries to cross the river and gets to the mill.
