题目内容：
Wall Street is the name of a street in New York and very famous in the whole world. It is the financial center of the U.S.A, exerting a significant influence upon the world’s economy. Hetty Green, who was born in 1835, was nicknamed the Wizard（奇才）of Wall Street. She became almost a legendary figure in Wall Street, because she made a lot of money buying and selling shares in companies.
Hetty Green began making money when her father died and she inherited all his money. By investing it wisely, she soon built up her fortune to over 100 million dollars. However, she hated spending money on herself or on her family. Actually, she hated spending money on everything except buying shares. She was so mean that when her son Edward broke his leg, she would not send for a doctor. She did not want to have to pay a doctor’s bill. She refused to send her son to a good hospital. Instead, she took the boy to a free charity hospital. There he did not get very good treatment and, to save his life, he had to have his leg cut off. Still his mother would not pay for proper hospital treatment. She sent for a doctor who cut off the boy’s leg in her sitting room. It’s incredible, isn’t it?
