She was a poor girl who worked to get money to pay for her lessons. She became the famous woman scientist of her time. That's the story of Marie Curie's life. She didn't mind working and she didn't care about the honors(荣誉)that were given to her in later years.

Marie was born in 1867. Her name was Marie Sklosovska then. She lived in Poland. Her father was a teacher. Everyone soon saw that Marie had a quick mind.

Marie's mother died when her youngest daughter was only ten. From then on, Marie knew that she would have to work hard at her lessons if she wanted to be successful(成功的)in her life. She studied very hard and was one of the best students at her school.

Marie and her older sister, Bronya, wanted to study in France at the Sorbonne. But their father didn't have enough money to send them there. It was Marie who had an idea: she would teach at home and send her money to Bronya. After her sister finished studying in Paris, she would get work and send Marie the money to study there herself. So Marie worked very hard for six years to pay for her sister's studies. At last it was Marie's turn but when she got to France, her sister was married and could not give her much help.

Again Marie worked. She studied in a small room without heat or light. She lived on bread and tea most of the time. But all she thought of was her maths and science. This was her world.

After four years' hard work, Marie and her husband found something which was called radium(镭). They were given the Nobel Prize(诺贝尔奖)for their great discovery(发现). But they were too ill to go Stockholm themselves to receive it.

Marie always said that it was because of her children that she want her work. And she discovered a hidden power and gave it to the world. It was the same power, however, that killed Marie in 1934.

材料一：很多人认为，这场战争（鸦片战争）标志着中国社会向近代社会的转型，我则认为，中国传统社会向近代文明的转型，在明中后期就已经开始。

——裴钰《改变中国》

材料二：19世纪末到20世纪前半叶，中国的近代企业呈现出沿着纺织、缫丝、面粉为中心的民间轻工业，军需工业、船舶修造、机械工业等政府主导的重工业两个方向发展，与此同时，在上海和东北等地设立的外国企业，在向中国引进技术方面来说也发挥了特殊的作用和具有特殊的意义。

——朱荫贵（《日本学术界对中国近代经济史研究的两个新动向》

材料三：新文化运动的倡导者们认为，中国所以危亡，民主和科学所以不能实现，是由于封建伦理道德的严重束缚所致。陈独秀尖锐地指出：孔子学说为代表的封建伦理道德，阻碍了中国人民觉醒和社会进步。李大钊发表文章指出，孔子是“数千年之残骸枯骨”“历代帝王专制之护符”“保护君主政治之偶像”，……对于不合时宜的旧道德，“虽冒毁圣非法之名，亦所不恤矣”。

——马尚斌等编《中国近代史教程》

材料四：这三十年来，有一个名词在国内几乎做到了无上尊严的地位；无论懂与不懂的人，无论守旧与维新的人，都不敢公然对它表示轻视或戏侮的态度，那个名词就是“科学”。

——胡适《（科学与人生观）序》（1923年）
