| While Pierre Curie [[tận tâm]] himself chiefly to the physical study of the new radiations, Marie Curie struggled to obtain pure radium in the metallic state. | devoted |
| On May 13, 1906, she was appointed to the professorship that had been left [[trống rỗng]] on her husband’s death, becoming the first woman to teach at the Sorbonne. | vacant |
| The sudden death of her husband in 1906 was a bitter blow to Marie Curie, but was also a turning point in her career: [[từ nay trở đi]] she was to devote all her energy to completing alone the scientific work that they had undertaken. | henceforth |
| Turning her attention to minerals, she found her interest drawn to pitchblende, a mineral whose radioactivity, could be explained only by the presence in the ore of small [[số lượng]] of an unknown substance of very high activity. | quantities |
| One of Marie Curie’s outstanding achievements was to have understood the need to accumulate intense radioactive sources, not only to treat illness but also to maintain an [[dồi dào]] supply for research. | abundant |
| Turning her attention to [[khoáng sản]], she found her interest drawn to pitchblende, a mineral whose radioactivity, could be explained only by the presence in the ore of small quantities of an unknown substance of very high activity. | minerals |

| Pierre Curie joined her in the work that she had [[đã thực hiện]] to resolve this problem, and that led to the discovery of the new elements, polonium and radium. | undertaken |
| From childhood, Marie was remarkable for her [[phi thường]] memory, and at the age of 16 won a gold medal on completion of her secondary education. | prodigious |
