听力原文：M: Andrew Jackson, who was President of the United States from 1829 to 1837, was one of the most colorful political figures in American history. He first won national attention during the War of 1812 when, as the commander of about 5.000 backwoods farmers and soldiers, he completely defeated a well-trained British army of 10,000 men at the famous Baffle of New Orleans. There are many anecdotes about Jackson. Among them there is a humorous one: After his wife died, Jackson lived alone and felt very lonely. He also began to worry greatly about his health. Several members of his family had died after suffering paralytic strokes, and Jackson was sure that he was going to die in the same way. He therefore lived in constant fear of having such a stroke. One day at the home of some friends, he was playing chess with a young girl. Suddenly Jackson's hand dropped to his side and he seemed to become very weak. His face became pale. Several friends rushed to his side. 'At last it has come,' said Jackson weakly. 'I have had a stroke. My whole right side is paralyzed.' 'How do you know?' someone asked. 'Because,' Jackson answered, 'in the past few minutes I have pinched my right leg several times, and there is absolutely no sensation in it.' 'Oh! I beg your pardon, Sir,' said the young woman with whom he had been playing. 'But that was my leg you were pinching!' Who was Andrew Jackson?
