  • 27、Hobbs was an orphan. He worked in a factory and every day he got a little money. Hard work changed him thin and weak. He wanted to borrow a lot of money to learn to paint pictures, but he did not think he could pay off the debts. One day a lawyer said to him, “One thousand dollars, and here is the money.” As Hobbs took the package of notes, he was very dumbfounded(惊呆了的). He didn't know where the money came from and how to spend it. He said to himself, “I could go to find a hotel and live like a rich man for a few days, or I give up my work in the factory and do what I'd like to do: painting pictures. I could do that for a few weeks, but what would I do after that? I should have lost my place in the factory and have no money to live on. If it were a little less money, I would buy a new coat, or a radio, or give a dinner to my friends. If it were more, I could give up the work and pay for painting the pictures. But it is too much for one and too little for the other.” “Here is the reading of your uncle's will,” said the lawyer, “telling what is to be done with this money after his death. I must ask you to remember one point. Your uncle has said you must bring me a paper showing exactly what you did with his money, as soon as you have spent it.” “Yes, I see. I will do that,” said the young man.统考英语阅读理解
