一天，小马驮着麦子去磨坊。
当他驮着口袋向前跑去时，突然发现一条小河挡住了去路。小马为难了，这可怎么办呢？
它向四周望了望，看见一头奶牛在河边吃草。小马问道：“牛阿姨，请您告诉我，这条河我能趟过去吗？”
奶牛回答说：“水很浅，刚到膝盖。”
小马正准备过河，突然丛树上跳下一只松鼠，拦住它大叫道：“小马，别过河！你会被淹死的。昨天，我的一个伙伴就在这条河里淹死啦！”小马不知如何是好，于是决定回家问问妈妈。
小马把路上的经历告诉了妈妈。妈妈说：“孩子，光听别人说是不行的，你自己亲自去试一试，就知道答案了。”
小马回到河边，刚要下水，松鼠又大叫起来：“小马，你不要命啦？”
小马说：“让我自己试试吧。”它一面回答一面下了河，小心地趟了过去。原来河水既不像老牛说的那样浅也不像松鼠说的那样深。
这下明白了吧，实践才能出真知。
【 How a Colt Crossed the River】
One day， a colt took a bag of wheat to the mill.
As he was running with the bag on his back，he came to a small river.
The colt could not decide whether he could cross it. Looking around，he saw a cow grazing nearby. He asked，“Aunt Cow， could you tell me if I can cross the river?”
The cow told him that he could and that the river was not very deep，just knee high.
The colt was crossing the river when a squirrel jumped down a tree and stopped him.
