阅读理解 Jim, a young farmer, was once put into prison. 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 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.
