第一节

阅读下面短文，从每小题所给的A、B、C、D四个选项中选出最佳选项。

Deng Jiaxian was born in Huaining,Anhui Province,on 25 June,1924.He entered the Physics Department of the Southwest Associated University（西南联大） in 1941.After graduation in 1945,he taught in middle schools and later in the Physics Department of Peking University. In 1948,he entered the Graduate School of Purdue University in the United States and received a PhD（博士学位） in physics two years later. After Deng’s graduation,he didn’t accept the high‑paid jobs and superb research conditions provided by the American government or universities. Instead,he returned to China in 1950 to work on nuclear（核能） research.

Deng Jiaxian set up classes,giving lessons himself and organising people to translate and study foreign language materials. At the same time,he never gave up on his ideas regarding the main direction of atomic bomb（原子弹） development. Following the successful test of the atomic bomb,Deng and his team joined the research group led by Yu Min in 1965 and immediately started designing the hydrogen bomb（氢弹）.Within no more than one year,they handed in the Deng‑Yu Project. It made China’s hydrogen bomb develop much faster.

In the nuclear experiments,Deng always stood in the front line and never made his colleagues（同事） do the dangerous work for him. Unfortunately,he got radiation sickness（辐射病） in the early 1980s. However,he continued to work until 1985 when he had to stay in the hospital.
