Appreciation of Zhang Hengchuan

This article is a typical biography, which comprehensively describes Zhang Heng's life and many talents in science, politics, literature and other fields. Moreover, it is meticulous and outstanding, focusing on his contribution to science, which runs through the author's sincere admiration for Zhang Heng's moral character. Clear-cut, well-organized, a well-read, calm and indifferent scholar image comes into view. This article can be divided into three parts. The first part is paragraph 1 of the article. Describe Zhang Heng's academic, moral and literary achievements. The first two sentences describe Zhang Heng's name, birthplace and family background in the form of biographies of historical figures. Then he introduced his literary attainments. "Not very good at literature" shows that he has innate talent, while "wandering in the study of three auxiliary courses and watching the imperial examination because he entered the capital" shows that he pays attention to social practice. It is precisely because he laid such a deep and solid foundation in his youth and constantly improved himself that he can "master the Five Classics and Six Arts". After describing his "talent", he immediately described his virtue. "Although I am superior, I am not arrogant and often calm. It is not good to make friends with laymen. " He has a modest and steady personality and transcends vulgarity. Facing the invitation of the ruler, the author uses words such as "no", "no" and "no" to express his noble character. Erjing Fu further confirmed his literary talent and spirit of intensive research. The second part, the second to fourth paragraphs, introduces Zhang Heng's scientific and technological achievements. This paper mainly introduces the structure and function of the seismograph. The second and third paragraphs summarize Zhang Heng's achievements in science as a whole, including scientific inventions and theoretical works. When introducing its specialties, it is linked with its officials, which reflects the causal relationship between them. The fourth paragraph focuses on the seismograph, which can represent its achievements. Although the introduction of the seismograph is less than 200 words, it describes the manufacturing time, texture, size, shape, internal and external structure, decoration and function in detail. And the words are concise and plain. If the four directional words "middle", "side", "outer" and "lower" are taken as the order when introducing structural features, the structural features should be written concisely from the inside out and from top to bottom. It is very vivid and concrete to describe its shape with "wine sample", and the accuracy of the instrument is described with exaggerated description of "testing with facts and combining with spirit" and enthusiastic praise of "recording from books, nothing left". Finally, attach vivid and interesting events to verify its efficacy, so that the article can reveal its feelings in a plain way. The third part, the fifth and sixth paragraphs, introduces Zhang Heng's political talent. The article only selects two things as the starting point. First, the origin of Si shows Zhang Heng's thoughtful and cautious ideological image. The first is his struggle with traitors when he became Hejian Xiang. "Knowing the traitor's name clearly and collecting birds for a while" shows his political wisdom, and "awe from top to bottom is called political management" shows his outstanding achievements. Although there is little pen and ink in this way, it has written an honest official who is truly affectionate and righteous, with both form and spirit. Concise and clear language is the outstanding feature of this paper. The author seldom uses adjectives when writing, tries to grasp historical facts, and cherishes ink as gold when describing, without repeating a word. However, there are some wonderful things in the plain spirit, such as a vivid description in The Seismograph after the Wind, which shows that the author has his own hills and valleys in his chest, so he can be simple, decent and flexible. Only in this way can the major events in many fields in Zhang Heng's life be clearly and methodically explained.
