Tom was a happy shepherd. Each morning, after having breakfast, Tom would tell his mother, "Mama, I am full. Now, I will bring our sheep out into the fields to graze." Each morning, his mother would say to him, "Ok, be careful! Be sure to take care of our sheep, and protect them from the cunning wolf!" One day, Tom brought his flock of sheep to a grassy hill to graze. He was humming a cheerful tune when driving his sheep. Suddenly, out of the bushes jumped a scrawny wolf. "Go away, bad wolf!" Tom shouted nervously. However, the wolf did not attack his sheep. Instead, it followed quietly behind. Tom felt confused by the wolf's strange behavior, and guarded his flock of sheep closely.

The next day, Tom brought his sheep out to graze as usual. The wolf continued to follow quietly, and did not attack his sheep. Tom thought to himself, "This wolf does not want to eat my sheep. It even follows behind to protect them. Maybe it is a good wolf!" Slowly, Tom stopped keeping an eye on the wolf. On the third day, The wolf gobbled up some sheep while Tom was resting under a tree. By the time Tom realized what happened, it was already too late. The wolf had filled its belly and ran away. Tom said, "I should not have trusted the wolf and lowered my guard. It is too late for regrets now."

　　小乖是一個快樂的牧羊人，每天早上吃完豐盛的早餐後跟媽媽說：「媽媽，我吃飽了，我現在要出門帶小羊去吃草。」媽媽回答說：「好，路上小心，你要好好地保護小羊不要被壞心的狼給吃掉喔！」說完小乖就帶著一群小羊到山坡上去吃草，小乖一邊哼著歌，一邊趕著羊群。突然，從路旁的草叢裡跳出一隻瘦小的狼，嚇得小乖緊張地大叫：「壞野狼，快走開！」但是說也奇怪，這隻狼不吃羊，只是默默地跟隨著羊群走，小乖很疑惑，但還是十分謹慎的保護著羊群們。

　　第二天小乖照樣出門趕著羊去吃草，這一天狼也繼續跟著羊群走在後頭，一點也沒有想要搶走羊的意思。小乖心想：「這隻狼不但不會偷吃我的羊，還會跟在後頭保護我的羊群，說不定牠是一隻善良的狼呢！」因此，小乖漸漸的不再防備這隻狼。到了第三天，當小乖在山坡的大樹下休息時，狼趁小乖不注意就吃掉了幾隻小羊，小乖發現後著急地想要阻止，狼卻早已填滿肚子逃走了，小乖後悔地說：「我真是活該，不該掉以輕心，現在後悔也來不及了。」
