47、Mark Twain was famous as a writer, but he was also famous as a public speaker and teller of funny stories. He often went from town to town giving lectures. One day he was walking along the street of a small town where he was going to give a lecture that evening. He met a young man who said, "Mr. Twain, I'd like to talk to you for a minute, please. I have an uncle that I'm fond of. The problem is he never laughs or smiles. Can you do anything?" "Bring your uncle to my lecture this evening, young man. I guarantee that he'll laugh and smile." That evening the young man and his uncle sat in the first row. Mark Twain spoke directly at them. He told some funny stories, but the old man never smiled. Then he told the funniest stories he knew, but the old man's face still remained blank（茫然的）. At last, Mark Twain left the platform almost exhausted. Later Mark Twain was talking with a friend about this. "Oh!" said the friend, "I know that old man. He has been deaf for years."统考英语阅读理解
