请英语高手答题：
It was in Paris that Marie met and married Pierre Curie,a young scientist who had already won respect.
Together they made their experiments in an old wooden house that was too cold and damp (潮湿) for their health.They knew that some elements (元素) in the world gave off a strange power that could go through other objects.They found more of this power in some elements than in others,which made them believe that it must be a new element itself.
For years they tried experiments to separate this powerful new element.Then they found something which they called radium (镭).Its power was very much greater than the power contained (包含) in other elements.
The Curies were given the Nobel Prize for their great discovery,but they were toe ill to go to Stockholm themselves to receive it.They used the money for further experiments on the uses ‘of radium.They found it could be used in treating diseases.
Pierre died suddenly just after he had been offered a good post at,a university.Marie Curie was given the post.She thus became the first woman ever to teach there.She continued their work and made many more important discoveries.In 1911 she received another Nobel Prize.It is the only time in history that two Nobel Prizes have been given to the same person.
