B. Famous deeds of fighting for ideals

(1) In order to confirm Goldbach's conjecture, Chen Jingrun taught himself English, German and even Russian. Whether it is hot or cold, Chen Jingrun will spend more than ten hours studying Goldbach's conjecture. When Chen Jingrun confirmed Goldbach's conjecture, the draft paper of optical calculus was packed in several sacks.

He wrote the research results of Goldbach's conjecture into the paper "Even number represents the sum of the products of a prime number and a prime number not exceeding two". Once published, "Big even number represents the sum of the products of a prime number and a prime number not exceeding two" immediately attracted the attention of international mathematicians.

British mathematician Haberstein and German mathematician Li Xite spoke highly of Chen Jingrun's Goldbach conjecture, and wrote the research results of Chen Jingrun's Goldbach conjecture into a book named Chen Theorem.

(2) Tu Youyou has been engaged in the research of integrated traditional Chinese and western medicine for many years, creating new antimalarial drugs artemisinin and dihydroartemisinin. A colorless crystal with the molecular formula of C 15H22O5 was successfully extracted from 1972 and named artemisinin.

20 1 1 In September, artemisinin, a drug used to treat malaria, saved millions of lives around the world, especially in developing countries, and won the Lasker Prize and the "Outstanding Achievement Award in Life Science" of GlaxoSmithKline China R&D Center.

20 15- 10 Tu Youyou won the nobel prize in physiology or medicine for discovering artemisinin, which can effectively reduce the mortality of malaria patients. She became the first China person to win the Nobel Prize in Science.

(3) Stephen Hawking was born in Oxford, England on 1942 10. He was terminally ill when he was young. However, he persevered, overcame his pain and became a world-renowned scientist. Hawking went to Cambridge University for postgraduate study after graduating from Oxford University. At this time, he was diagnosed as "Luger's disease" and soon became completely paralyzed.

He became a world-recognized giant of gravitational physics in the incredible difficulties of ordinary people. Hawking is a Luxun professor of mathematics at Cambridge University. His black hole evaporation theory and quantum cosmology not only shocked natural science, but also had a far-reaching impact on philosophy and religion.

(4) Ma Yun, Alibaba, a small online workshop with 18 people and 500,000 yuan, became the world's largest B2B business website eight years later; Eight years later, the small sampan drifting in the West Lake became the Internet carrier of China in the Pacific Ocean. Eight years later, this ordinary English teacher became the head of a world-class Internet company.

(5) Deng Yaping, she was born in a table tennis family, and her father Deng Dasong was a table tennis player in Henan Province. Since Deng Yaping was more than two years old, his father often put Deng Yaping on a bicycle and took Deng Yaping to the workers' club to watch them play. Deng Yaping learned to play table tennis with his father at the age of 5, and his father developed a set of training methods different from routines.

At first, Deng Yaping shot horizontally. Because Deng Yaping was slow and had short arms, she was asked to take publicity photos the next year. Deng Yaping was particularly serious since she was a child. Deng Yaping encountered many difficulties in her growth.

Because she is short, the provincial team doesn't want her. My father told Deng Yaping all this. Deng Yaping understood his father's meaning: if others say you can't do it, you should fight for breath and practice more. Therefore, Deng Yaping was excellent since she was a child, and her training was particularly hard.

(2) The story of science 100 words for further reading:

Goldbach conjecture is one of the three major mathematical problems in the modern world. Goldbach put forward the following conjecture in his letter 1742 to Euler: any even number greater than 2 can be written as the sum of two prime numbers.

But Goldbach himself could not prove it, so he wrote to the famous mathematician Euler to help him prove it, but until his death, Euler could not prove it. Because the convention that "1 is also a prime number" is no longer used in mathematics, the modern statement of the original conjecture is that any integer greater than 5 can be written as the sum of three prime numbers.

Any sufficiently large even number can be expressed as the sum of a number with no more than one prime factor and a number with no more than b prime factors, and the proposition is called "a+b". 1966 Chen Jingrun proved that "1+2" holds, that is, "any sufficiently large even number can be expressed as the sum of two prime numbers, or the sum of a prime number and a semi-prime number".

Tu Youyou, female, pharmacist. 1930 was born in Ningbo, Zhejiang province on February 30th, and was admitted to Peking University in195/0, studying in the department of biochemistry and pharmacy of medical college. 1955, graduated from Beijing Medical College (now peking university health science center).

After graduation, he received Chinese medicine training for two and a half years and has been working in China Academy of Traditional Chinese Medicine (renamed China Academy of Traditional Chinese Medicine in 2005). During this period, he was promoted to master tutor and doctoral tutor, and now he is the chief scientist of Chinese Academy of Traditional Chinese Medicine. Lifelong researcher and chief researcher of Chinese Academy of Traditional Chinese Medicine, director of artemisinin research and development center, doctoral supervisor, pharmacist, winner of Nobel Prize in Medicine.

E. How to improve English

Now I want to learn English, no matter what the reason is. Everyone needs to find a way that suits them. Now many so-called English learning methods are drawing cakes. Give you a beautiful picture, and when you try it yourself, you will find it. These are actually useless. Even if you know that you really follow this method, you may succeed. But you will still choose to give up. The reason is simple: you are not him, you are not the successful person.

So for me, if I want to learn English successfully, two methods are feasible. Only these two methods can really suit the public and those who want to learn English now.

Method one, find a teacher.

G. Scientists' stories, good words and sentences

Mao Yisheng (1896 65438+1October 9-1989 65438+1October 12) is a Chinese bridge scientist, civil engineer, educator and social activist. Tang Chen, a native of Zhenjiang, Jiangsu. My ancestral home is Mao Qian, and my previous business life was full of people, progressive thoughts and revolutionary tendencies. He once founded Nanyang Official Newspaper, a celebrity in Zhenjiang. Shortly after Mao Yisheng was born, the whole family moved to Nanjing. At the age of six, he went to a private school. At the age of 7, I studied at No.41 School, the first new primary school in China founded by Nanjing 1903. 19 1 entered Jiangnan Business School, 1 was admitted to Tangshan Road and Mining School. 19 12, Dr. Sun Yat-sen pointed out the importance of mining and repairing railways, and strengthened the road of "saving the country by science" and "building the country by engineering" in Mao Yisheng. From then on, he studied harder and regarded building the motherland as his own responsibility. The result of each exam is the first in the class, and the average score of each subject in five years is 92.5, which is rare in the history of this school. 19 16 graduated from the civil engineering department of Tangshan Institute of Technology. The following year, he received a master's degree in civil engineering from Cornell University. 192 1 received his doctorate in engineering from Gary Institute of Technology. His doctoral thesis "Secondary Stress of Bridge Truss" is called "Mao's Law" and won the "Fittis" Gold Research Medal of Cornell University. After returning to China, he served as professor of Tangshan College of Jiaotong University, director of engineering at Southeast University, president of Hohai University of Technology, dean of Beiyang Institute of Technology, director of Qiantang River Bridge Engineering in Hangzhou, dean of Tangshan Institute of Technology of Jiaotong University, and director of Bridge Design and Engineering Department of Kuomintang Ministry of Communications. After the establishment of People's Republic of China (PRC), he served as President of Northern Jiaotong University, Director of Railway Research Institute of Ministry of Railways, Dean of Railway Research Institute, Second Vice-Chairman and Honorary Chairman of China Association for Science and Technology, Chairman of Beijing Association for Science and Technology, Member of Chinese Academy of Sciences, Third Chairman of china civil engineering society, Senior Member of the 5th-7th China Bridge and Structural Engineering Society of Jiu San Society, and Member of the International Society of Soil Mechanics and Basic Engineering. In 1930s, Mao Yisheng's achievements in the engineering technology of Qiantang River Bridge made foreign counterparts look at the bridge-building engineers in China with new eyes. In 1950s, during the construction of Wuhan Yangtze River Bridge, Mao Yisheng served as the chairman of the technical advisory committee composed of Chinese and foreign experts, and solved 14 problems in the construction of Wuhan Yangtze River Bridge. 1979 When he was invited to visit the alma mater of Kalicky Mellon University, the president awarded him the "Outstanding Alumni" medal in recognition of his contribution to world engineering technology. 1982 was awarded the title of foreign academician by the National Academy of Sciences. 1933, he led the design and construction of Hangzhou Qiantang River Bridge, the first railway and highway bridge designed and built by China people. He also participated in the construction of Wuhan Yangtze River Bridge, the first modern bridge in New China. 1959 served as the head of the structural review team of the Great Hall of the People and contributed his own technology, experience and wisdom to this historic building. Mao Yisheng is an important founder of bridge engineering in China. As an educator, Mao Yisheng has served as a professor in five schools, the presidents of two universities and the deans of two colleges during his more than 20 years' educational career. He actively advocated popular science education and wrote many popular science articles such as Qiao Hua and China Stone Arch Bridge.

Mao Yisheng was studious and enterprising since childhood, and was good at independent thinking. When he was 10 years old, a dragon boat race was held in his hometown during the Dragon Boat Festival. All the people watching the game stood on Wende Bridge. Because there were too many people, the bridge collapsed and killed many people. This unfortunate incident weighed heavily on Mao Yisheng's mind. He secretly made up his mind that when he grew up, he must build the strongest bridge. From then on, whenever Mao Yisheng saw a bridge, whether it was a stone bridge or a wooden bridge, he always saw enough from the deck to the bridge column. After Mao Yisheng went to school, he saw articles and paragraphs about bridges from books, so he copied them in his notebook. When he saw pictures about the bridge, he cut them out and pasted them on. After a long time, he accumulated several thick notebooks.

After graduating from high school, Mao Yisheng was admitted to the Department of Civil Engineering of Tangshan Institute of Technology. After graduating from Tangshan Road Mine 19 16, he was sent to the United States for postgraduate study with the first place, and set off for Cornell University in September. Who knows that the director of the school's registration office proudly said: "Tangshan, China has never heard of this school, and you must pass the exam to register." . After the examination, Mao Yisheng got excellent grades, so he applied for the postgraduate of bridge major. Since then, the graduates of Tangshan Road and Mine School have been sent to Cornell University for postgraduate study, and they are no longer allowed to pass the exam. Mao Yisheng received his master's degree from Cornell University Graduate School on 19 17 and his doctor's degree in engineering from Gary Leakey Institute of Technology on 19 19. The title of the doctoral thesis is "Secondary Stress of Bridge Mechanics", which was first-class in the world at that time, so it won the gold medal for scientific research awarded by Gariji Institute of Technology. 19 19 12, 24-year-old Mao Yisheng resolutely returned to China and became a professor at Tangshan College of Jiaotong University. Mao Yisheng said: "Looking back on my study and life, this 14 year effort is like building a bridge, which has built a solid pier for my life." After returning to China, Mao Yisheng successively served as a professor of Tangshan Institute of Technology, a professor and director of engineering at Nanjing Southeast University, the president of Hohai University of Technology, the president and professor of Tianjin Beiyang Institute of Technology, the director of Jiangsu Water Resources Bureau, the general manager and chief engineer of China Bridge Corporation of the Ministry of Communications, and the president of Northern Jiaotong University.
