根据材料内容，选择正确答案。

    Jim, a young farmer, was once put into prison (监狱).

    One day, he got a letter from his mother. "I'm so worried about our farm," she wrote. "It's time to plant potatoes. I can't dig(挖) all the fields by myself. "

    Jim read the letter and became sad. "What can I do?" he thought. Then he had a good idea. He wrote to his mother, "Don't dig the fields. There's a pot of money in the earth. Don't plant potatoes until I come home."

    Some days later, Jim got another letter from his mother. It said, "Two days ago, about ten men came to our farm and dug all our fields. I can't understand it. It looks as if they were looking for something. What shall I do?"

    Jim smiled when he read his mother's letter. He wrote a letter to his mother at once. It was very short. Guess what it would say?

       黔无驴，有好事者船载以入。至则无可用。放之山下。虎见之，庞然大物也，以为神，蔽林间窥之。稍出近之，慭慭然，莫相知。

他日，驴一鸣，虎大骇，远遁，以为且噬己也，甚恐。然往来视之，觉无异能者；益习其声，又近出前后，终不敢搏。稍近，益狎，荡倚冲冒。驴不胜怒，蹄之。虎因喜，计之曰：“技止此耳！”因跳踉大阚，断其喉，尽其肉；乃去。
