Deep sadness spread across China's social media as news spread that famous physicist Chen-Ning Yang had passed away. Yang, a Nobel Prize winner and academician of the Chinese Academy of Sciences, died in Beijing at the age of 103.
Yang was born in 1922 in Hefei, Anhui Province, at a time when China was poor. He studied at Tsinghua University and later went to the United States to further his education. Yang became famous for his work on parity laws（宇称定律）with Tsung-Dao Lee. Their work challenged an old idea in physics and won them the Nobel Prize in Physics in 1957. He also worked with Robert Mills on the Yang-Mills theory, which helped set up the Standard Model of Particle Physics（粒子物理标准模型）. This is considered one of the cornerstones of modern physics.
Yang settled down in China and taught at Tsinghua University in 2003, helping students become outstanding scientists. His students described him as energetic, modest and calm, with a clear mind. Even in his 80s, Yang continued teaching. He encouraged students to do top-level research and use science to solve real problems in China.
Yang's contributions went beyond research. At age 99, he donated more than 2,000 books, letters, and papers to Tsinghua. He said, "I hope Tsinghua keeps not only my scientific work, but also the truth about who I am."
Netizens left plenty of heartfelt messages online to express their feelings about the great scientist. One netizen wrote, "He is a towering giant in the field of physics, proving to the whole world that Chinese scientists can reach great heights." Another pointed out, "Through his lifelong scientific career, Yang built a valuable bridge connecting Chinese and Western science study."

三、信息还原（10分）
As we all know, Wang Xuan was one of the most famous computer scientists and inventors. 1. As a result, he is known as "The Father of the Chinese Language Laser
Typesetting（激光排版）".
Since there is a big difference between Chinese and English writing systems, laser typesetting for the Chinese language was a serious problem for scientists all over the world. 2. In 1975, he began researching laser typesetting and electronic publishing systems for Chinese characters. He was not afraid to try new technology. 3. He spent most of his spare time on experiments. He often worked late into the night in his lab.
Wang Xuan's great invention is widely used all over the world. 4. Besides, it has brought huge benefits to China's newspaper publishing industry and supported the development of China's printing business.
Wang Xuan was not only a great modern scientist but also a great role model for many young people. 5. His life story teaches us that a person should follow his own dream and try his best to make it come true.
A. We middle school students should learn from him.
B. He invented the technology for printing Chinese characters.
C. Wang Xuan only focused on newspaper printing all his life.
D. He spent all his free time reading science books at a young age.
E. Although he didn't have success all the time, he never gave up.
F. For this reason, Wang Xuan decided to try to come up with a method.
G. It has greatly lowered printing costs and saved plenty of time for printing workers.
