Marie Curie was a Polish-born physicist and chemist and one of the most famous scientists of her time. Together with her husband Pierre, she was awarded the Nobel Prize in 1903, and she went on to win another in 1911.

Marie Sklodowska was born in Warsaw on 7 November 1867, the daughter of a teacher. In 1891, she went to Paris to study physics and mathematics at the Sorbonne where she met Pierre Curie, professor of the School of Physics. They were married in 1895.

The Curies worked together investigating radioactivity, building on the work of the German physicist Roentgen and the French physicist Becquerel. In July 1898, the Curies announced the discovery of a new chemical element, polonium. At the end of the year, they announced the discovery of another, radium. The Curies, along with Becquerel, were awarded the Nobel Prize for Physics in 1903.

Pierre's life was cut short in 1906 when he was knocked down and killed by a carriage. Marie took over his teaching post, becoming the first woman to teach at the Sorbonne, and devoted (= to give your time or effort completely to something you believe in or to a person, or to use a particular amount of time or energy doing something) herself to continuing the work that they had begun together. She received a second Nobel Prize, for Chemistry, in 1911.

The Curie's research was crucial (= extremely important or necessary) in the development of x-rays in surgery. During World War One Curie helped to equip ambulances with x-ray equipment, which she herself drove to the front lines. The International Red Cross made her head of its radiological service and she held training courses for medical orderlies (orderly= a hospital worker who does jobs for which no training is necessary, such as helping the nurses or carrying heavy things) and doctors in the new techniques.

Despite her success, Marie continued to face great opposition from male scientists in France, and she never received significant financial benefits from her work. By the late 1920s her health was beginning to deteriorate (= become worse) . She died on 4 July 1934 from leukaemia (= سَرطان الدَمّ (اللوكيميا), caused by exposure to high-energy radiation from her research. The Curies' eldest daughter Irene was herself a scientist and winner of the Nobel Prize for Chemistry.

Answering Tag Questions:

How do we answer a tag question? Often, we just say Yes or No. Sometimes we may repeat the tag and reverse it (They don't live here, do they? Yes, they do). Be very careful about answering tag questions. In some languages, an opposite system of answering is used, and non-native English speakers sometimes answer in the wrong way. This can lead to a lot of confusion!

Answer a tag question according to the truth of the situation. Your answer reflects the real facts, not (necessarily) the question.

For example, everyone knows that snow is white. Look at these questions, and the correct answers:

Tag question	Correct answer	*Notes*
Snow is white, isn't it?	Yes (it is).	Answer is same in both cases - because snow is white!	But notice change of stress when answerer does not agree with questioner.
Snow isn't white, is it?	Yes it is!	Answer is same in both cases - because snow is white!
Snow is black, isn't it?	No it isn't!	Answer is same in both cases - because snow is not black!
Snow isn't black, is it?	No (it isn't).	Answer is same in both cases - because snow is not black!

In some languages, people answer a question like "Snow isn't black, is it?" with "Yes" (meaning "Yes, I agree with you"). This is the wrong answer in English!

Here are some more examples, with correct answers:

The moon goes round the earth, doesn't it? Yes, it does.

The earth is bigger than the moon, isn't it? Yes.

The earth is bigger than the sun, isn't it? No, it isn't!

Asian people don't like rice, do they? Yes, they do!

Elephants live in Europe, don't they? No, they don't!

Men don't have babies, do they? No.

The English alphabet doesn't have 40 letters, does it? No, it doesn't.
