1862年的一天,一名老妇人去拜访刚刚在伦敦作完报告的美国博物学家路易斯·阿加西斯博士。她向博士抱怨自己没有机会学习,因为她总有做不完的家务。听了这个女子的话,阿加西斯博士问:“你是说,夫人,你从未有机会?那么你一天都干些什么?” One day in 1862, an old lady went to visit Dr. Louise Agascis, a U.S. naturalist who had just finished a report in London. She complained to the doctor that she did not have a chance to learn because she always had endless housework. After listening to this woman, Dr. Agassiz asked: “You mean, Madame, you have never had a chance? What are you doing all day?”
