问题：

Marie Sklodowska was the daughter of a Polish teacher. She was a very intelligent little girl; she could read when she was only four years old. Her father taught science at a school in Warsaw. Marie went to his school when she was fourteen years old. She was very interested in science and mathematics, and liked to help his father in his laboratory. She was a very good student and left school with a gold medal.

Marie wanted to be a scientist like her father. In 1891 her sister Bronya invited her to go to Paris. There she began to learn science and mathematics at the famous university of the Sorbonne. At first Marie could speak only a little French, but he worked hard and soon passed her examination. In Paris Marie met another scientist Pierre Curie, and in 1895 she married him.

In 1898 both the Curies decided to investigate the radioactive elements in pitchblende. The Austrians gave them a lot of pitchblende for their work, and the Curies began to experiment with it slowly and carefully. They worked hard for four years, and at last Marie obtained a very small piece of radioactive element—radium. It weighed only one tenth of a gramme, but it was pure radium and it shone with a wonderful light. The new element was valuable to science, but it was beautiful too.
