In one year, Chen Jingrun graduated from the Department of Mathematics of Xiamen University, and was once kept in school. He worked as a librarian in the library. Apart from sorting out books and materials, he was also responsible for correcting homework for students of the Department of Mathematics. Despite the tight time and busy work, he kept on studying mathematics science. Oh, by the way, the teacher at ABC Tianbian English Center, where I am currently attending, said that it is easy to learn English well. There must be an appropriate learning situation and an object to practice oral English. The most important thing is the foreign teacher's oral English standard. Only by practicing oral English 1v1 daily without interruption can you have a very good learning effect ... After learning, you should also review the classroom recording files repeatedly to further deepen your knowledge ~ Then, if there is really no environment for practicing objects, go to VOA or Hujiang to get after-school learning materials, practice speaking more and asking more questions, and your sense of language will be improved. Learning and growth will advance by leaps and bounds .. Chen Jingrun has a strong interest in mathematical theory, and has systematically read the monographs on mathematics by Hua Luogeng, a famous mathematician in China, using all available time. Chen Jingrun studied Russian, German, French, Japanese, Italian and Spanish while continuing to learn English in order to read foreign materials directly and master the latest information. Learning these foreign languages is an amazing breakthrough for a mathematician, but it is only the first step for Chen Jingrun. Chen Jingrun was born in a poor family. When his mother gave birth to him, he didn't have milk, so he survived by borrowing rice soup from his neighbors. The age of going to school, because the father who works as a clerk in the post office earns too little for his eldest brother to go to school, and his mother has to work in the fields with her little sister under two years old on her back. In this way, the burden of looking after my little brother on weekdays falls on Xiao Jingrun's shoulder. During the day, he led his little brother to sit on a small bench and count his fingers. In the evening, when my brother left school, he begged him to tell him the math. A little older, I squeezed out the gap to help my mother work in the fields and was busy practicing writing and calculus. Seeing that he was eager to study, his mother sent him to Chengguan Primary School. Although he is thin and thin, he works very hard and gets good grades, which makes some children jealous and kicks him. He couldn't beat those people, so he went home in tears and asked to drop out of school. His mother stroked his wound and said, "Son, it's only because we are poor that we are bullied." You should be eager to learn, fight for breath, grow up and be promising, and then they won't dare to bully us! " Xiao Jingrun dried his tears and went to do his homework again. Since then, he has never shed tears again, turning his physical and mental pain into a driving force for learning, and his grades have been top-notch. Finally, he was admitted to Sanyuan County Junior High School with the first place in the school. In junior high school, he was paid special attention by two teachers: one was a Chinese teacher who was nearly sixty years old, and was a professor. He witnessed the Japanese bullying, but the people gave in one after another, and felt saddened. Unfortunately, he was old and pinned his hopes on the next generation. Seeing that Chen Jingrun was hardworking and promising, he often called him to his side to tell the history of China's civilization for thousands of years, encouraging him to study hard and shoulder the heavy responsibility of saving the motherland. Teachers often speak with tears in their eyes, and Chen Jingrun also says with tears that when he grows up, he will definitely serve the motherland! The other is a math teacher under the age of , who graduated from the Department of Mathematics of Tsinghua University with rich knowledge. Chen Jingrun is most interested in math class, a textbook, which took only two weeks to finish. The teacher felt that this student was unusual, so he made extra efforts to tell him more, and further stimulated his patriotic enthusiasm, saying, "If a country and a nation want to be strong, it is absolutely impossible for natural science to be underdeveloped, and mathematics is the foundation of natural science." From then on, Chen Jingrun loved mathematics even more. Until I graduated from junior high school, I kept a record of straight A in mathematics. After the recovery of the motherland, Chen Jingrun was admitted to Yinghua College in Fuzhou to attend high school. Here, he was lucky enough to meet Mr. Shen Yuan, who made him unforgettable all his life. Mr. Shen used to be the director of the aviation department in Tsinghua University, then the director of Chen Jingrun and taught mathematics and English. Mr. Shen is knowledgeable and persuasive, and all his classmates like to listen to his lectures. Once, Mr. Shen came up with an interesting classical math problem: "Han Xin ordered soldiers". Everyone started to count, and Chen Jingrun quickly replied in a low voice: "People". All stunned by the speed of his calculation, Mr. Shen looked at this quiet and ill-dressed student and asked him how he got it. Chen Jingrun blushed and couldn't speak. Finally, he wrote the method on the blackboard with a pen. Teacher Shen said happily, "Chen Jingrun is very good, but he dare not speak. Let me help him!" Aft Mr. Shen finished, he introduce China's contribution to mathematics in ancient times, saying that Zu Chongzhi's research achievement on pi was 1, years earlier than that of Western Europe, and Qin Jiushao's solution to "joint linear equation" in Southern Song Dynasty was more than years earlier than that of Italian mathematician Euler. Teacher Shen then encouraged and said, "We can't stop. I hope you can create greater miracles in the future. For example, there is a Goldbach conjecture, which is still an unsolved problem in number theory. People compare it to the jewel in the crown. You should take it off!" After class, Teacher Shen asked Chen Jingrun what he thought. Chen Jingrun said, "Can I do it?" Teacher Shen said, "Since you can figure out' Han Xin points soldiers' by yourself, you will be able to pick up that pearl in the future: nothing is difficult in the world, and nothing is impossible to a willing mind!" That night, Chen Jingrun couldn't sleep, and he vowed: No matter how successful or unsuccessful he grew up, he would try his best. In 11 years, a reporter from the "I wish you success" column of Beijing TV Station once asked Chen Jingrun, "What is the purpose of life?" Chen Jingrun said: "It is dedication, not taking."
