Some people say that this "living fossil" of China's shipbuilding industry is not only to build a ship, but also to dream of making China the first shipbuilding power. In order to inherit his feelings, You Yang has donated his life savings of more than 6.5438+0 million yuan and established the "You Yang Scholarship", which inspired the younger generation to study hard and trained a large number of shipbuilding backbone elites. Huang Xuhua ("the father of China's nuclear submarine"), Xu Qinan (the chief designer of "Jiaolong"), Zhu Yingfu (the chief designer of China's first aircraft carrier Liaoning) and Zeng Hengyi (the designer of China's first offshore oil drilling ship) are all his students. He is a well-deserved colleague and witness in the development of China's marine industry.
How to write a good composition? First of all, examine the questions properly. The examination of college entrance examination composition is actually a kind of reading with a specific purpose. It requires the author not only to decompose the content and refine the meaning, but also to be good at judging the main tendency of the material as a whole, to capture the intention of the proposer from some hints, and to make his own judgment and choice on the theme of the material according to the limitations and requirements of the proposer. Therefore, the first point in the examination of material composition is to realize the overall cognition and grasp the main idea of the material. The second point is to silently read the composition questions word by word. You should circle the key words with a pen (so as not to deduct the text), or draw a horizontal line below.
Secondly, the structure is perfect, and the structure is actually very general. Think carefully at the beginning, use some famous sentences or poems, don't be too familiar, be atmospheric and highlight your own views. Two or three arguments, first analyze the relationship between arguments, arguments and your point of view, and describe your point of view. To put it bluntly, it is a set of words, one paragraph for each argument. Finally, parallelism, poetry and songs can be used, and you can also refer to excellent compositions to see what other people's models are.
Third, the proper use of inscriptions cannot be abused; It should be closely related to the composition materials; Summarize or deepen the main ideas; The language should be concise, and it is generally better to control it within one line. Writing a few crosses is often self-defeating; To prevent the inscription content from repeating the title and the first paragraph of the article.
Finally, the first and last paragraphs are very important. In these two paragraphs, you should use all the skills and improve all the tricks and witty sentences you can use. In addition, it is very important to echo from beginning to end, so that the article looks as a whole and will add points to the article.
