Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?Jane Addams(1860－1935)Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize.Rachel Carson(1907－1964)If it weren't for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world's lakes and oceans.Sandra Day O'Connor(1930－present)When Sandra Day O'Connor finished third in her class at Stanford Law School, in 1952, she could not find work at a law firm because she was a woman. She became an Arizona state senator (参议员) and, in 1981, the first woman to join the US Supreme Court. O'Connor gave the deciding vote in many important cases during her 24 years on the top court.Rosa Parks(1913－2005)On December 1,1955, in Montgomery, Alabama, Rosa Parks would not give up her seat on a bus to a passenger. Her simple act landed Parks in prison。
