原稿开头: The Biography of Benjamin Franklin I like to read biographies. I have read many biographies. From the lives of great or common people, I know more of the world, the society and the minds of people. Biographies enlarge my views and help me to grow up. I have read The Biography of Benjamin Franklin in Chinese when I was in middle school, Franklin' s extraordinary success inspired me greatly at that time. Last month our teacher Ms Li asked us to read The Biography of Benjamin Franklin in English, so I read it again and this time, I have a better understanding of his life and his success. 修改文稿: The Biography of Benjamin Franklin 本杰明·富兰克林传记 I have read The Biography of Benjamin Franklin in Chinese when I was in middle school.
