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. Deng Jiaxian passed away on 29 July,1986.He is considered as the “Founding Father of China’s A‑Bomb and H‑Bomb”. 16.What does the underlined word “superb” in Paragraph 1 mean? A. Silent. B.

Deng Jiaxian had no experience in leading a research team. 18.What is the main purpose of the passage? A. To explain the development process of China’s atomic bomb and hydrogen bomb. B. To introduce Deng Jiaxian’s life experiences and his contributions（贡献） to China’s nuclear research. C. To describe the working conditions of nuclear researchers in the 1960s and 1970s. D.

Among the three astronauts,a new face has drawn a lot of attention. He is Gui Haichao,a professor at Beihang University. Born in 1986 in Shidian,Yunnan Province,Gui grew up in a common family. When he was in primary school,he was known for asking lots of questions. There were only a few books he could get in the countryside school,but he spent much of his free time exploring the unknown world within the books. In high school,Gui was always the first to arrive at the classroom in the morning to study and the last to leave at night. His interest in aerospace began at the age of 17.That year,Shenzhou‑5 was successfully sent into space and Yang Liwei became China’s first astronaut in space. Gui studied even harder. Two years later,he entered Beihang University to learn aircraft design and engineering. To achieve his dream,Gui spent nine years taking his bachelor’s and PhD degrees（学士和博士学位） at Beihang University. Then he worked abroad for three years as a postdoctoral researcher. After returning to China,he began teaching and doing research at Beihang University.
