Sally 了解到邓稼先为中国核武器的研发做出了重要贡献，是两弹元勋。 阅读材料，选择正确的答案。
Deng Jiaxian(1924—1986) was a great nuclear scientist, known as China’s “Two Bombs Hero” for developing atomic and hydrogen bombs(氢弹). He spent his whole life making our country stronger and safer.
Deng was born in Anhui Province on June 25th, 1924. He loved to study at an early age and wanted to be a professor like his father. However, his father hoped he would learn science well to build a modern China. Deng studied hard and entered university in the end.
After finishing university in 1945, he taught physics at several middle schools at first and later worked as a physics teacher at Peking University. In 1948, Deng went to the US to study for his doctor’s degree in physics. This study usually takes four or more years. Although Deng was the youngest person in his class, he never wasted time. He earned his doctorate in physics in only two years. His classmates called him the “Baby Doctor”.

Why was Deng Jiaxian great?

1. A 解析 由文中“Deng Jiaxian ( 1924—1986 ) was a great nuclear scientist, known as China’s ‘Two Bombs Hero’ for developing atomic and hydrogen bombs (氢弹)”可知,邓稼先被称为“两弹元勋”,A选项正确。B选项“Medical Hero (医学英雄)”和C选项“Space Hero(太空英雄)”均不符合原文描述。
2. B 解析 文中提到邓稼先生于1924年,并由文中的“In 1948, Deng went to the US to study for his doctor’s degree in physics”以及“He earned his doctorate in physics in only two years”可知,他1948年赴美,两年后即1950年获得博士学位,1950 - 1924 = 26,所以他获得博士学位时26岁,B选项正确。
3. B 解析 由文中的“Although Deng was the youngest person in his class, he never wasted time. He earned his doctorate in physics in only two years. His classmates called him the ‘Baby Doctor’”可知,因为他是班里最年轻的,且用很短的时间就获得了物理学博士学位,所以同学们叫他“娃娃博士”,B选项符合文意。A选项“他看起来像个婴儿”和C选项“他喜欢婴儿”均与原文不符。
4. B 解析 根据常识以及原文对邓稼先回国后为中国研制两弹的描述可知,他没有永远留在美国,故A选项错误;结合文中提到的“He loved to study at an early age”“Deng studied hard and entered university in the end”“Although Deng was the youngest person in his class, he never wasted time”等内容可知,他学习很努力,故C选项错误;文中第一句明确提到“developing atomic and hydrogen bombs(氢弹)”,说明他为中国制造原子弹,故B选项正确。
开放回答: Because he loved his country and worked hard to make China stronger and safer. He helped China develop atomic and hydrogen bombs.(答案不唯一,合理即可)
