First of all, I want to call on you to protect the marine ecological environment. We ask too much of the ocean. The ocean provides us with all kinds of food, provides conditions for ships to sail and presents us with beautiful scenery. However, while using the ocean, human beings have not taken good care of it. Now she is facing various problems such as seawater pollution. Therefore, our urgent task is to curb the deterioration of the marine ecological environment and make it significantly improved. This requires the joint efforts of all people to establish the awareness of protecting the ocean as soon as possible.

The ocean is the cradle of human life. In the history of the world's oceans, there are Kyle Poirot who explored the Atlantic Ocean, Columbus who discovered the New World, Zheng He who made seven voyages to the West, and Magellan who sailed around the world. In the history of China's navigation, there are both the myth of Jingwei's reclamation and the legend of trouble at sea. There are both Lin Zexu's feat of smoking in Humen and the fiasco of Sino-Japanese Sino-Japanese War of 1894-1895. The ocean has brought us too many amazing stories and legends, and also brought us endless exploration of the unknown world.

China has 65,438+8,000 kilometers of coastline, 3 million square kilometers of blue land and rich marine resources. We can proudly say that we are a maritime power, but we can't say that we are a maritime power. 1840, foreign powers attacked our country with artillery fire, and our country began a humiliating century-old modern history. The sea is surrounded by strong neighbors and its national strength is weak. People with lofty ideals in China are heartbroken and run around looking for ways to save the country. Mr. Chen Jiageng, a famous patriotic overseas Chinese, witnessed the weakness of the country's maritime power and was bullied by foreign powers. 1920 Established Jimei Navigation Education in his hometown, determined to train advanced navigation talents for the country and enhance the country's navigation strength. It is precisely because many patriots like Mr. Jia Geng have made immortal contributions to the development of the motherland with the heart of serving the country. In June last year, the submarine "Jilong" dived 7000 meters deep, which means that China's marine scientific research strength has reached a new level; Shortly thereafter, there was exciting news that China's first aircraft carrier "Liaoning" was launched in Dalian and officially delivered to the navy for service. Hearing this news, I am extremely excited and proud of the gradual enhancement of the country's maritime strength and the progress of science and technology.

I know that the enhancement of national strength can not be separated from the efforts of many researchers, and I also want to be one of these researchers and make my own contribution to the country's scientific and technological progress. Fortunately, I took this step, successfully passed the postgraduate examination of Dalian Maritime University, and came to a middle school attached to the sea again, and had the opportunity to make efforts for marine development. The 18th National Congress of the Communist Party of China put forward "improving the ability of developing marine resources, developing marine economy, protecting marine ecological environment, resolutely safeguarding national maritime rights and interests, and building a maritime power". As a party member, it is our duty and responsibility to keep up with the pace of the Party and respond to its call. As national citizens, it is our mission to study scientific knowledge hard and make contributions to national scientific and technological progress.
