Question 17 is based on the passage you have just heard

听力原文：

    Most people know Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. (16) However, few people know that she was also the mother of a Nobel Prize winner.

    Irene Curie was born on September 12, 1897, at the age of 10, Irene’s talents and interest in Mathematics were apparent. Irene entered Sorbonne University in October 1914, to prepare for a degree in mathematics and physics. When World War I began, she left Sorbonne University to help her mother, who was using X-ray facilities to help save the lives of wounded soldiers. (17) Irene continued this work by developing X-ray facilities for military hospitals in France and Belgium. After the war, she received a Military Medal for her work.

    In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot visited the Institute, where he met Marie Curie. Frederic became one of her assistants and Irene taught him the techniques required to work with radioactivity. Irene and Frederic soon fell in love and got married on October 29, 1926. Their daughter was born in 1927 and their son in 1932.

    Like her mother, Irene combined family with career. (16) Like her mother, Irene was awarded a Nobel Prize, along with her husband Frederic, in 1935, for producing new radioactive elements. (18) Unfortunately, also like her mother, she developed blood cancer because of her exposure to radiation. Irene Joliot-Curie died on March 17, 1956.

17. For what was Irene Curie awarded a Military Medal?

解析：B。本题为细节题。问题为：Irene Curie为什么被授予军事奖章？根据原文“Irene continued this work by developing X-ray facilities for military hospitals in France and Belgium. After the war, she received a Military Medal for her work.”，可见Irene Curie继承了母亲之前的工作，为法国和比利时的军事医院开发X-ray设备，并在战后因此工作而获得军事奖章。选项B) She developed X-ray facilities for military hospitals.在原文中有直接体现，根据视听一致原则，为正确答案。
