When I was young, I was naive and interested in anything new. Probably, I don't touch the ocean, so I'm a little strange to the ocean and know nothing about it. It was not until June 65438+1October 65438+May 20 that Shenzhou 5 took Yang Liwei into space, and I gradually became interested in the ocean and learned more about it. This winter vacation is about to write a review of "Going to the Ocean".
Yang Liwei overlooks his home from the distant universe. He was very surprised. It turned out that the earth he saw was not the khaki and chaotic planet he imagined. On the contrary, it is a crystal clear blue sphere and a water polo. The ocean area on the earth accounts for 70.8% of the total land area. No wonder it looks like a water polo.
Human beings are endless, from apes to humans, from ancient times to today's development. These are inseparable from two things-water and air. Water is the most important thing, and all living things benefit from the ocean. The ocean is like a meticulous cradle, the birthplace of mankind. People have gone through a tortuous and long process of 30 billion to 40 billion years. And some birthmarks of the ocean. Since the birth of life in the ocean, the barren and lonely earth has ushered in the season of dead wood and spring, and the marine industry has flourished.
Generally speaking, the first stage of mankind's formation of ocean consciousness is the fear and worship of the ocean. For early humans, the ocean was full of mystery and crisis. It is precisely because of this concept that they have wonderful fairy tales that enlighten human wisdom and inspire human beings to sail bravely.
The second stage is the exploration of the ocean. It was not until 15 and 16 centuries that people really risked their lives and started to set out across the blue and into the deep blue sea. Kyle Poirot was the leader, and everyone was influenced by him, which led to the stories of Columbus, Zheng He and Magellan.
The last step is possession and development. The ocean has become no stranger to human beings, the myth has become a distant death, and exploration has become a romantic embellishment of daily monotonous life. The ocean has become an integrated dredging network, a conveyor belt of wealth and a duel field of desire.
The ocean has a long history, during which many famous figures and troops have emerged. At the same time, all kinds of "dreams of making money" are buried in the ocean, because it is the largest freshwater reservoir of mankind, rich in biological resources and rich in gasoline fields distributed on the seabed. Is nature's greatest wealth.
Time is gone forever. Let bygones be bygones! Let's look to the future and create an era of marine commercial civilization with China characteristics. China can declare to the whole world that China is not a weak person in the East, nor is it a soft persimmon that anyone can pinch, so that China's territorial waters can become a harmonious ocean and prosper.
The ocean is a bridge to inherit history and the future. People who have entered the 2 1 century have gradually strengthened their concept of protecting the ocean. We are convinced that the ocean will continue to develop with our human society!

Do you know how a rich world unfolds before our eyes?
According to the prediction of relevant medical experts, human beings will subdue cancer in 2 1 century. So, what is the panacea for mankind? In recent years, scientists have discovered that the ocean will become a drug warehouse in 2 1 century. The ocean is a cornucopia of mineral resources. After the "international 10 marine exploration stage" in the 1970s, people's understanding of the types, distribution and reserves of marine mineral resources was further deepened. Under the current technical conditions, although submarine hydrothermal deposits can't be mined immediately, it is a potential treasure house of seabed resources. Once it can be exploited industrially, it will become one of the four major seabed minerals in 2 1 century together with submarine oil, deep-sea manganese nodules and submarine placer.
Many primary school students think that China has a land area of 9.6 million square kilometers, but it is actually 6.5438+0.26 million square kilometers. The extra 3.6 million square kilometers is the land and sea area of our country.
Endless sea water covers the earth's surface, not the land. There are the most oceans on the earth, accounting for about 70.8% of the earth's surface area. Such a large ocean area must be rich in marine resources! Therefore, the ocean is rich. It is rich in resources, including marine plant resources, marine animal resources, marine aquaculture biological resources and marine microbial resources. There are about 200,000 kinds of marine animals, including giant whales, ferocious sharks, docile dolphins and various scallops ... there are about two kinds of marine plants. More than 50,000 species, mainly algae. Most marine plants are available for human use.
The ocean is a treasure house of blue. It has given us rich marine resources and brought us countless wealth. Water is the source of life, which breeds us human beings, that is, all living things. It feeds our children and grandchildren with sweet milk. Of course, it is also the largest fresh water reservoir for mankind, providing fresh water for mankind. Let's join hands to create a green barrier, protect the ocean, and roam the wonderful world of the ocean together!
Ocean, a very simple word, but the sea is the sea, and the ocean is the ocean. "Ocean" consists of sea and ocean. "Sea" refers to the subsidiary part of the ocean edge, and its area is usually relatively small. The oceans are divided into two categories: the Mediterranean and the marginal seas. The Mediterranean Sea is a sea area between continents that goes deep into the mainland. The marginal sea is a sea area located on the edge of the mainland. "Ocean" refers to the central part of the ocean, which is different from the ocean and has its own tidal and ocean current system. Ocean is also a big pharmacy, which contains huge clean energy. There are abundant oil and gas fields on the seabed. There are many secrets hidden in the ocean, and many great wars have also taken place on the ocean, which provides essential energy for our lives.
The global oceans are interlinked, and the interests of mankind are the same. When the bell of the ocean century rings, let's join hands, sing together and walk with the ocean. Make full use of the marine resources to make this vast country with12.6 million square kilometers more prosperous and powerful in the future.

The earth is a beautiful planet. When Yang Liwei, a space hero, went into space in the Shenzhou 5 spacecraft, he found that the earth was not a yellow chaotic planet, but a blue planet. A crystal-clear sphere. We should call him water polo.
From the ocean to the land, and then from the land to the sky, the history of human development can be described as colorful, but in the final analysis, the ocean is our "hometown." In this mysterious blue area, there are many mysteries. Maybe you will say it's amazing: at a seaside near the forest, a creature climbed out one night and screamed-maybe this is the origin of human civilization. There used to be more creatures living here, so there is today's colorful world. I never expect to live by the sea, but I am proud that my ancestors once lived in the sea. In this blue world, there are wonderful performances every day!
Speaking of the ocean, we have to talk about its long and glorious history. From the eastward voyage of Yin people to Xu Fu's voyage to the Maritime Silk Road, various stories related to the sea emerge one after another. But what I like best is the history of Zheng He's seven voyages to the West. This historical event is of great significance. It shows the tenacious exploration spirit of the ancient people of China, broadens the horizons of the people of China, and promotes the economic and cultural exchanges and friendly exchanges between China and many Asian and African countries. At sea, there are also many beautiful and moving stories. From Jingwei's reclamation to where to make trouble with the sea, from mermaid to the daughter of the sea, they grow up with generation after generation. People began to live by the sea and make a living by the sea. Gradually, they developed from being afraid of the ocean to loving it. They found countless treasures in the ocean and kept asking for them. Even today, people are still asking about everything about the ocean. Although the marine resources are abundant, they should be developed moderately, otherwise they will be at the end of their tether.
Of course, the sea also has memories that make us ashamed, that is, the Sino-Japanese War and the Opium War. At that time, the imperialists bombed China with ships, which reduced China to a semi-colonial and semi-feudal society, and China people were once called "the sick man of East Asia". This historical fact that once humiliated China cheered us up. After the founding of New China, we fully realized the advantages of China's1.8000 km coastline and actively developed and strengthened the navy. Today, the powerful China stands in the east of the world, and the powerful China navy is cruising in the world ocean. Various warships and submarines independently developed by China have provided many guarantees for China's national defense, and have always defended our maritime borders and our great motherland. China has also become a soaring Asian dragon.
After reading this book, I not only know the history of China's "blue land" ocean, but also know the secrets of the ocean. For example, there are 80% of the world's creatures in the ocean, 90% of the world's fresh water (icebergs in the north and south poles) and 300 billion tons of exploitable oil and natural gas! Not only that, at least 265,438+0,700 ships are sunk every century, and some ships are full of treasures, worth about 600 billion dollars, which is a lot of money when converted into adult currency! Of course, who will look at such a large sum of wealth and immerse themselves in this boundless ocean forever? Some people try to salvage this wealth to make a fortune, but they often pay more and get less. I think in the near future, technology will be several times more developed than it is now, and those treasures that have been immersed in the sea for a long time will surely "see the light of day"! Now, exploiting oil and gas is no longer a dream. But oil leakage at sea is a very terrible thing. We should take good care of the ocean and don't let those innocent fish bear the mistakes we made!
In the future, the secrets of the ocean will be completely discovered by human beings, and the ocean will be the same as the land: human beings live on it, and they also have high-rise buildings and beautiful grasslands. . . . . .
Looking ahead, the ocean will continue to advance with us. In this strange blue world, there are more things waiting for us to discover. In the future, we will become stronger and stronger with the prosperity of the ocean. Facing new difficulties, new life and new people, the ocean will also shoulder heavy responsibilities and face it bravely!

With the progress of science and technology and the development of the times, a new era of developing the ocean has arrived. In the process of developing the ocean, people will get more wealth from the ocean more effectively. More and more countries are planning to establish or have established undersea pastoral areas and undersea pastures, and people are gradually transitioning from the simple era of marine fishing in the past to the era of "cultivating the sea" in the future. In the near future, people will work better and more effectively in undersea pastoral and undersea pasture than on land, because the output of marine culture is 100 times higher than that of land farming in the same area. People will breed a large number of seaweed and seaweed as feed for cattle, pigs and sheep on land to obtain more protein, and the total output of underwater pastoral areas in the world will soon jump from the current 20 million tons to 50 million tons. A large number of seaweed and seaweed will also be harvested by underwater combine harvesters and then hoisted to the ship by steel cables.
In the near future, the fishing nets used by people for generations will be replaced by powerful water absorption devices. Using the light emitted by electric field, sound with certain frequency and special compounds dissolved in water, fish can be lured and forced to gather together and swim close to the suction pipe laid down on board, and the suction pipe will be sucked into the cabin together with the fish carrying water. By that time, people will get more than 654.38 billion tons of seafood from the ocean, ten times or even dozens of times more than what they get from the ocean now.
With the increasing demand for oil, natural gas and other resources in the world and the massive exploitation of these resources, these resources on land will be exhausted day by day. People will inevitably look to the ocean or look for new energy sources. It is estimated that the seabed oil reserves are about 90 billion tons, and the oil reserves in the Arctic Ocean alone can be used by the world for 50 years. At present, more than 100 countries and regions have explored and developed continental shelf and deep-sea oil, and more than 500 oil and gas fields have been discovered. The implementation of a ten-year world offshore drilling plan is coming to an end. Explore and develop submarine oil and build a production base on the seabed. For the transportation problem after submarine oil exploitation, people will use large submarines. Imagine sinking a huge plastic cylinder into the bottom of the sea, which is filled with 654.38+10,000 tons of crude oil and towed by a submarine. Some people also designed to transport it by spaceship.
There is a huge amount of energy in the ocean, which is called the "blue ocean of coal" and will be transformed into the future energy of mankind. In the future, the marine thermal energy conversion plant will be located in the sea, and electricity can be supplied to cities through coastal cables. The content of heavy water in seawater called "future fuel" is much higher than that in land water. Hydrogen isotope can be extracted from heavy water, and scientists are using it for thermonuclear reaction experiments. If successful, it will become an inexhaustible source of energy.
In the near future, people will also build "underwater cities", which is not an illusion, but a reality. At present, Japan has built a "small city" for Arab countries to swim at sea. Most of it is made of steel, and the center is a six-story building. There is a small indoor garden, a cinema, and all the water and electricity are self-provided. Can meet the needs of cultural and recreational life of offshore oil production workers. The floating city is supported by eight tall pillars. Put them away and you can sail like a boat. In the future, many offshore factories will be built in the sea near raw material production sites or markets to provide materials for urban residents at sea. In Longchuan Bay, southwest of Shikoku Island, Japan, there is a "park in the sea". People can enjoy the wonders of the seabed through the 60 cm diameter 16 glass window: grotesque rocks, colorful corals, all kinds of strange fish, strange starfish and anemones. Since the first underwater laboratory was built in the United States, many countries have followed suit and built "steel houses" and other buildings on the seabed. The air pressure in the "house" is the same as the sea surface, and people can work normally in it, repair oil and gas wells on the seabed, salvage sunken ships, explore the seabed or replenish submarines. It is also reported that a group of Japanese engineers and architects. It is planned to build the world's first "marine city" in the sea area from Tokyo 120km to solve the human settlement problem in the future. Ocean City will be built at a depth of 200 meters, with a four-story steel platform, about 70 meters away from the sea surface and covering an area of 23 square kilometers. The whole city will be supported by 65,438+00,000 solid columns, and induction devices will be installed near the columns. We can measure typhoons, tsunamis and undercurrents, adjust ourselves to resist these external pressures and maintain the stability of Ocean City. In addition to residential areas, Ocean City also has a commercial center, 400 tennis courts, 8 golf courses, 2 baseball fields, 1 artificial fields for growing fruits and vegetables, and roads connecting vertically and horizontally. The construction cost of Ocean City is estimated to be 200 billion dollars, and this huge project is expected to be completed by the end of this century. By 2 1 century, this "undersea city" will be inhabited by more than 1 10,000 people. At that time, the deep seabed will no longer be silent, and it will become as lively as the mainland. More and more people will explore it, build it and paint this grand blueprint with their own wisdom and hands.
The future of the ocean shows people brilliant prospects, and the vast ocean will make great contributions to mankind!

On Saturday, I came across a book called Going to the Ocean in my brother's schoolbag. The cover of this book is very distinctive: in the vast blue sea, two dolphins chase each other and splash; In the distance, a sailboat set sail in the wind; In the air, seagulls circled bravely on the sea ... such a book with marine characteristics attracted me deeply, and I couldn't help reading it.
Going to the ocean, as the name implies, is a book related to everything in the ocean. This book introduces the intimate relationship between human beings and the ocean from three aspects. The first part tells the story of human beings from worship to exploration and from recognition to struggle, which opens the origin of human culture. The ocean is a big treasure house, rich in biological resources, rich in oil and gas, gold and silver jewelry. Of course, the ocean is also the largest freshwater reservoir in the world. If the seawater is purified, it can alleviate the water shortage problem all over the world. The second part describes the relationship between the ocean and the Chinese nation in detail. China has a long history of navigation, with the Yin people crossing eastward, Xu Fu going to sea, the Silk Road, and the forbidden sea and locked the country, which has written down the highlights of China's history. The Asia-Pacific War, the Sino-Japanese War and the War of Aggression against China are all important naval battles in China's maritime history. The ocean and celebrities complement each other. Zheng He, Zheng Chenggong and Wei Yuan are all famous figures in marine history. China's maritime defence should not be underestimated. Teams of aviation and motherships, submarines and small water ships defend our motherland. The third part looks forward to the future of the ocean. The future of the ocean is "blue", going to the world, connecting China and the world, and also the last space for human survival and sustainable development!
We have always said that "the ocean is the cradle of life, the origin of civilization, the blue treasure and the ultimate destination of mankind." After reading this book, I realized that it proved that water is one of the important factors in human evolution. It not only gave birth to us, but also is the cradle of culture. Human beings have provided us with many services by developing fresh water resources, chemical resources, biological resources, mineral resources, energy resources and space resources in the ocean. Such a long history and culture, so many beautiful ideas, wishes and plans are all built on a beautiful and healthy ocean. Looking back at our current ocean, the earthquake in Japan caused the explosion of nuclear power plants, oil leakage from seagoing ships and the invasion of "red tide" ... all of which caused immeasurable damage to our beautiful ocean. Since ancient times, we have lost many plants and animals, which is a warning from nature.
We should be vigilant and protect the remaining poor creatures so that species will no longer disappear; We should act, save resources and cherish every drop of water, every piece of paper and every grain ... Only when our ocean becomes more beautiful and healthy can more people show their ambitions in this vast ocean and let the ocean provide us with better services; Only when the "Mother Earth" on which we live is no longer riddled with holes will Mother Earth be willing to give her everything. Let all people in our society unite, rationally develop marine resources and strive to be the guardians of the environment.
