If you've ever seen your insides on an x-ray，you can thank Marie Curie for being able to see them so clearly.
   Marie was born in Poland on November 7，1867.Her father，who taught math and physics，helped her develop a talent for science early.As she grew older，she wanted to go to university and learn all about physics.But women students were not allowed in the local university.Dreaming to become a scientist and work on her experiments，she moved to Paris，F(xiàn)rance，to study physics at a university.
   In 1895，she married Pierre Curie.Together they discovered two new radioactive elements（ 放射性元素），and won the Nobel Prize in physics in 1903.And she became the first woman to win any kind of Nobel Prize.Then she continued to make more amazing achievements in science.In 1906，she became the first woman physics professor at the university.In 1909，she was given her own lab at the University of Paris.Then in 1911，she won a Nobel Prize in chemistry.She's still the only person—man or woman—to win the Nobel Prize in two different sciences.
   She soon started using her work to save lives.She used her understanding to help the x-ray take detailed pictures inside the human body.In 1914，during World War I，she created mobile x-ray units that could be driven to hospitals.She also helped train some women to operate the units.With these x-ray units，doctors could see broken parts inside soldiers' bodies clearly and help save over one million soldiers.
   After the war ended in 1918，Marie Curie returned to her lab to continue working with radioactive elements.But those can be dangerous in a very large amount，and on July 4，1934，she died of a disease caused by radiation.
   Marie Curie was a woman hero，not only because of her groundbreaking and life-saving scientific work.She encouraged，and today she continues to encourage women to work in science，and scientists to use their work to help people.
