Today is Earth Day! These earth-related knowledge can be told to children.

Today is the 53rd Earth Day.

April 18-April 24

It is the theme publicity week of World Earth Day.

This year’s publicity theme is

"Cherish the earth and live in harmony with nature"

Protect the earth on which we live.

Is everyone’s responsibility.

Now we should also pass on this sense of responsibility to the children.

heretofore

Let’s learn about the origin of Earth Day!

The World Earth Day, that is, April 22nd every year, is a festival specially set up for world environmental protection, aiming at raising people’s awareness of existing environmental problems, mobilizing people to participate in the environmental protection movement, and improving the overall environment of the earth through a green and low-carbon life.

10 Cold Knowledge about the Earth

The word "Earth" in English originated from "Erda" in Anglo-Saxon (Old English), which means "ground" and "soil". Although the name is "ground", 71% of the earth’s surface is covered with water.

The mass of the earth is 5.975× 10 24 kg. Today, it is still accumulating comets, meteorites, cosmic dust and interstellar molecules in space. According to experts’ estimation, the earth can get about 100,000 tons of interstellar matter every year, including 23,430 tons of cosmic dust. Therefore, the earth grows a little fatter every year.

Since the birth of the earth from chaos 4.6 billion years ago, more than 1 trillion species have lived and multiplied on it. How many living things are there on the earth now? Go to the small garden in front of the door and dig a spoonful of soil with a spoon. There are more organic organisms living there than there are people on the earth.

About 620 million years ago, the earth’s day was only 21.9 hours. It can be seen that the rotation speed of the earth is gradually slowing down, but for us, the range is negligible-only 70 milliseconds every 100 years, so we have to wait another 100 million years if we want an extra hour in the day of the earth.

In history, there have been many magnetic pole reversals on the earth, from north to south and from south to north, and the most recent one was 780,000 years ago. Some scientists suspect that the reversal of the earth’s magnetic pole was the cause of ancient biological extinction.

Thanks to Jupiter, our earth can survive safely in the universe. Jupiter is big, massive, rotates fast, and its gravity is bigger than that of ordinary planets. The meteorites that originally flew to the earth were attracted by Jupiter and crashed into it one after another.

The earth is the only known planet with plate structure. Seven huge plates are moving in different directions, shaping the ever-changing geological features on the earth. Although it only moves 1-10 cm a year, the global carbon cycle depends on it by a few centimeters a year, so as to prevent the earth from overheating.

Man’s exploration of space has never stopped since ancient times. However, with the launch of satellites and space stations, there are more and more space junk. In 2014, a NASA data said that there were 2,600 failed but in-orbit satellites floating over the earth, twice as many as working satellites. According to the statistics of American space monitoring network, there are 26,000 objects in orbit over 10 cm, and 50,000 objects over 1-10 cm, most of which are space junk.

The water in ninety-seven percent on the earth is salt water. Of the remaining 3% fresh water, 70% is frozen in polar regions, and most of the rest is in soil or deep underground which is difficult for human beings to draw.

About 300 million years ago, almost all the land on the earth was a whole. During the Jurassic period, Pangea split into two continents, and with the passage of time, they split into what they are now.

What can we do to care for the earth?

The earth is our common home.

Each of us should have the responsibility to protect it.

Keep it from getting hurt.

Tell the children what we can do.

Garbage sorting is very important.

What else can I do with the milk cartons left over from breakfast today? Can I load things? Can you put it in the material supermarket? Can it be used to paint and decorate our classroom?A lot of "garbage" isIt can be reused.

When we throw garbage, we have toPay attention to the classification, you canThe importance of reuseSend it to the recyclable trash cannautical/sea mile, toxicYes, tooSend it to "harmful waste" so that small animals can’t eat it.Do a good job of garbage separationClass, we can save resources and prevent garbage from polluting the environment.

Protect animals and plants

Be friendly with small animals and protect them. If you are a little scared, you can stay away, but you can’t hurt them.

多植树，保护花花草草。

节约水、节约电

我们出门前、睡觉前要记得关灯，不使用电器的时候也要记得关闭电源。

洗手的时候要及时关好水龙头，喝水的时候喝多少接多少，不浪费。

低碳出行

开车会消耗汽油、还会排出很多有害的尾气。

我们出行可以尽量选择公共交通、自行车或者走路，在天气晴朗的时候，大家也可以多去户外骑车、健步走等，既锻炼了身体，放松了身心，也降低了能耗。

做个环保宣传小卫士

记得把这些环保知识教给家人，提醒家人垃圾分类、出门时提醒家人关灯、吃饭的时候呼吁大家一起“光盘”……

让更多的人一起来爱护地球，这样地球才能感觉到，环境才会变得越来好！

American War Crimes Record ｜ Sharp Reference

　　Reference News Network reported on March 19 (text/Ping Yue Jiang Tao Huang Jin Zhang Weiwei) Former US President Jimmy Carter mentioned in a speech in June 2019 that only 16 years in the history of more than 240 years since the founding of the United States did not fight, which is called "the most combative country in the history of the world." In the words of Dakota Wood, a senior researcher in the defense program of the American Heritage Foundation, the United States is involved in a war every 15 years on average.

　　Since the end of World War II, the United States has launched or participated in many wars overseas, such as the Korean War, the Vietnam War, the Afghan War, and the Iraq War, which have caused extremely serious civilian casualties and property losses and caused huge humanitarian disasters. Since 2001, the war and military actions launched by the United States in the name of anti-terrorism have caused more than 900,000 deaths, of which about 335,000 were civilians, millions were injured and tens of millions were displaced.

　　In today’s world, the hegemony, hegemony and bullying of the United States are obvious to all. In the major overseas wars directly launched or participated by the United States after the Cold War, the war crimes of this superpower are obvious.

　　:: Bombing Kosovo

　　[Time] March 24, 1999-June of the same year

　　[Crime] Without the authorization of the United Nations, NATO, led by the United States, carried out a continuous bombing of the then Federal Republic of Yugoslavia for 78 days under the banner of "preventing the humanitarian crisis in Kosovo". On May 7th of that year, the US forces involved in NATO bombing attacked the Embassy of China in Yugoslavia with missiles, which killed three China journalists, seriously injured many others and severely damaged the premises. In June of the same year, NATO signed an armistice agreement with Yugoslavia, and Kosovo was temporarily entrusted by the United Nations.

　　The war killed more than 2,000 innocent civilians, injured more than 6,000 people, displaced nearly 1 million people, and lost more than 2 million people’s livelihood, resulting in economic losses of more than 200 billion US dollars to Yugoslavia. According to statistics, NATO troops used at least 31,000 depleted uranium bombs, which led to a sharp increase in the incidence of cancer and leukemia in this region and had a long-term disastrous impact on the local and European ecological environment.

　　▲ On March 24, 2010, in Mitrovica, located in the north of Kosovo, Serb residents held the Serbian flag at a rally to mourn the victims of NATO air strikes against Yugoslavia 11 years ago. (Xinhua News Agency)

　　【 Consequence 】 In 2008, Kosovo unilaterally declared "independence". Serbia has always adhered to its sovereignty over Kosovo. The British "Guardian" published an article on the 10th anniversary of NATO bombing of Yugoslavia, saying that NATO bombing actually escalated the Kosovo crisis into a full-scale humanitarian disaster. German writer Michael Luders once wrote in his book that after the Kosovo War in 1999, NATO went beyond the principle of collective self-defense and launched a military operation against Yugoslavia, which caused civilian casualties in the name of humanitarianism. This shows that in the eyes of the United States and the European Union, human rights are only a secondary concern, especially when human rights standards are only applied to non-allies.

　　Iraq War

　　[Time] March 20, 2003-December 18, 2011

　　[Crime] Many countries, such as the United States and Britain, launched a military operation codenamed "Iraq Freedom" on the grounds that Iraq possessed "weapons of mass destruction". A few months after Saddam Hussein’s regime was overthrown, the United Nations indicated that its inspectors had not found any weapons of mass destruction. On December 18, 2011, with the withdrawal of the last batch of American soldiers, the Iraq war officially ended.

　　According to statistics, this war caused about 200,000 to 250,000 civilian deaths, of which more than 16,000 were directly killed by the US military and more than 1 million were homeless. The British "Guardian" reported that the Coalition forces led by the United States used a large number of depleted uranium bombs and white phosphorus bombs. A report from the Dutch peace organization PAX showed that American warplanes and tanks used nearly 10,000 depleted uranium bombs in the Iraq war in 2003, which led to a sharp increase in the birth defect rate of Iraqi babies after the war.

　　▲ On March 20, 2003, on the day of the war, a building in Baghdad, the capital of Iraq, caught fire after being hit by a US cruise missile. (US Department of Defense website)

　　【 Consequence 】 After Saddam Hussein was overthrown, the United States dissolved Iraq’s military, security and intelligence infrastructure organizations during Saddam Hussein’s time, creating a huge security vacuum in Iraq and opening the door to armed militia organizations that were not controlled by the state.

　　According to the website of the Gulf News of the United Arab Emirates, a bloody sectarian civil war broke out in Iraq, which led to the emergence of the "Islamic State" organization. What the United States left in Iraq was an ignominious legacy — — Corruption is rampant, public services are poor, armed militia organizations are everywhere and sectarian differences are deepening.

　　The war in Afghanistan

　　[Time] October 7, 2001-August 30, 2021

　　[Crime] After the September 11th terrorist attacks in 2001, the United States and its allies launched a military strike against Afghanistan in early October of that year on the grounds that the Taliban in Afghanistan refused to hand over Osama bin Laden, the leader of Al Qaeda, and quickly overthrew the Taliban regime and stationed troops for a long time on the grounds of anti-terrorism. On August 30, 2021, the last US military transport plane took off from Kabul International Airport. This "longest war in American history" ended in the sudden withdrawal of the US military. This war, which lasted for nearly 20 years, caused 47,245 Afghan civilians and 66,000 to 69,000 Afghan soldiers and policemen who had nothing to do with the "September 11" incident to die in the US military operations, and more than 10 million people were displaced.

　　▲ On December 16, 2003, the US military patrolled Wardak province in central Afghanistan. (Xinhua News Agency)

　　【 Consequence 】 The war in Afghanistan spanned the term of four American presidents and evolved into the longest war in the United States, so long that it itself became a "hasty stop" in the "9.11" era in the United States. The article in the British weekly New Politician pointed out that the Taliban’s victory in Afghanistan was not only called a solid blow to the dignity and reputation of the United States, but also a public denial of the foreign policy called "liberal intervention".

　　The United Nations World Food Program warned in 2021 that about 98% of Afghans do not have enough food, and Afghanistan is facing "avalanche hunger and poverty". After the United States withdrew from Afghanistan, it imposed economic sanctions on the Taliban regime and frozen billions of dollars of foreign exchange assets of the Central Bank of Afghanistan in the United States, which led to the collapse of the Afghan economy. The interim government formed by the Taliban needs to deal with the problems of striving for international recognition, restoring economic and social order, and cracking down on the extremist organization "Islamic State". Coupled with frequent natural disasters such as earthquakes and floods, Afghanistan still faces a serious economic and humanitarian crisis.

　　:: Air strikes against Libya

　　[Time] On the evening of March 19th, 2011.

　　[Crime] A riot broke out in Libya, which quickly developed into a civil war. On the grounds of the human rights crisis, the United States led NATO countries to indiscriminately bomb the Libyan government and military institutions under the banner of protecting citizens in Benghazi. According to the data released by NATO, from the end of March to the beginning of June of that year, NATO has dispatched 10,000 sorties, destroying about 1,800 targets. The air strikes also caused a large number of civilian casualties. According to the website of the Canadian Center for Globalization Studies, NATO fighters deliberately targeted the tents set up in front of Gaddafi’s official residence and brutally slaughtered civilians, but the mainstream media described these civilians as "radicals".

　　▲ On March 20, 2011, Libyan government vehicles burned and exploded after being attacked by air (Xinhua/Reuters)

　　【 Consequence 】 Gaddafi was overthrown by the opposition, Libya’s economy quickly regressed, the country was completely divided, and it was caught in a stalemate in which the two regimes confronted each other with international support behind them. In addition, the rampant terrorist organizations have taken root in Libya, and Libya is still mired in war today.

　　Alan cooper Mann, an associate professor at the University of Texas at Austin, wrote in Foreign Affairs magazine that when the United States and its allies intervened in Libya in 2011, the civil war in Libya was nearing the end. At that time, about 1,000 people were killed, and at least 10,000 people were killed after western intervention. Since then, Libya has been in turmoil for a long time, with economic collapse, tribal scuffles and extremism. The refugee problem caused by this has finally caused great economic and social pressure on Europe. The United States, as the initiator, stayed out of it. At the same time, in the process of crossing the Mediterranean, refugee ships have caused many humanitarian disasters due to the constant capsizing accidents.

　　The United States, Britain and France jointly attacked Syria militarily.

　　[Time] In the early morning of April 14th, 2018,

　　[Crime] On April 7, 2018, some anti-government figures in Syria claimed that Syrian government helicopters dropped bombs containing chemical agents on the town of Duma that day. The United States identified the Syrian government as launching a chemical attack on the Duma as an excuse to use force against Syria. The Syrian government said that the so-called chemical attack in Duma was fabricated. In the early morning of April 14, 2018, the United States, Britain and France carried out a "precision strike" against Syria without the authorization of the United Nations, and fired more than 110 cruise missiles and air-to-surface missiles at Syrian military and civilian facilities from the air and sea, causing at least six Syrian civilians to be injured. In order to "prove innocence", the United States has continuously released videos on the Internet about the Syrian people being attacked by chemical weapons. However, more and more evidence shows that the videos published by western media are suspected of fraud.

　　After the civil war broke out in Syria in 2011, the United States and its western allies strongly supported the Syrian opposition armed forces, which led to the local war and conflict continuing to this day. Since 2017, the United States has launched an air strike against Syria on the grounds of "preventing the Syrian government from using chemical weapons." From 2016 to 2019, Syria recorded 33,584 civilians who died in the war. Among them, 3833 people were directly killed by the bombing of the United States-led Coalition forces, half of whom were women and children. On November 9, 2018, the American public television network reported that only the so-called "most accurate air strike in history" launched by the US military on the city of Raqqa killed 1,600 civilians.

　　▲ On April 16, 2018, in the town of Duma, the eastern suburb of Damascus, Syria, a child received food on the street. (Xinhua News Agency)

　　【 Consequence 】 The US-led military strike has further complicated the situation in Syria. According to a survey conducted by the World Food Program in April 2020, about one third of Syrians do not have enough food, and 87% of them have no savings. According to the estimation of Doctors of the World, since the beginning of the war in Syria, about 15,000 doctors (about half of the total number of doctors in the country) have fled the country, 6.5 million people have been internally displaced and 5 million people have fled as refugees.

　　The United States and its western allies strongly supported the Syrian opposition armed forces and tried to overthrow the Syrian government by supporting agents, which led to local wars and conflicts that have continued to this day. The civil war has made Syria the bloodiest battlefield in the Middle East, expanded the ethnic and sectarian rift in Syria, led to the expansion of extremist forces, the spillover of the refugee crisis, and the constant violent conflicts, making the situation in the Middle East more turbulent.

　　▲ On April 14, 2018, on the north side of the White House in Washington, USA, people held slogans to protest against military strikes against Syria. (Xinhua News Agency)

　　In addition to the above-mentioned head-on conflicts, the United States has also adopted such "unconventional" wars as "shadow war" (assassination by using remote-controlled drones and "targeted killing" by dispatching small-scale special forces in the Middle East, Africa and Asia) and "proxy war" (supporting the Mujahideen guerrillas during the Soviet invasion of Afghanistan and the recent conflict between Russia and Ukraine).

　　According to a report on February 28th, 2023 on the website of the US Capitol Hill Daily, "From January 2022 to January 2023, the amount of US military assistance to Ukraine has reached $77.5 billion".

　　Christopher Kelly and Stuart Laycock, American historians, pointed out in their book "American Aggression: How We Invaded or Intervened in Almost Every Country on the Earth" that among the more than 190 countries recognized by the United Nations, only three countries have not fought with the United States or been subjected to its military intervention. These three countries were able to "survive" because "the United States did not find them on the map."

　　Tufts University’s research report "Military Intervention Project: A New Data Set of American Military Intervention from 1776 to 2019" shows that from 1776 to 2019, the United States conducted nearly 400 military interventions around the world, 34% targeted Latin America and the Caribbean, 23% targeted East Asia and the Pacific, 14% targeted the Middle East and North Africa, and 13% targeted Europe. At present, US military intervention in the Middle East, North Africa and sub-Saharan Africa is on the rise.

Young eagles spread their wings! China Air Force, which grew up in the War to Resist US Aggression and Aid Korea.

The War to Resist US Aggression and Aid Korea is of great significance in the history of the development of China People’s Liberation Army. The harsh war has accelerated the transformation of our army from a single infantry unit to a modern combined army of various services and arms, and promoted the modernization of the people’s army. The growth of the People’s Air Force is a typical example.

The People’s Air Force grew rapidly in the War to Resist US Aggression and Aid Korea.

On January 21, 1951, the Chinese people’s Volunteer Army Air Force engaged in the first air battle with the US Air Force. The 28th Brigade, 10th Regiment, 4th Division of the Volunteer Air Force injured a US plane. From the shooting photographic film of Captain Li Han, it was the F-84 bomber that was hit. At this time, they took off together with the Soviet Air Force and studied actual combat for only one month.

Sun Weitao (then Secretary and Translator of Air Force Commander Liu Yalou): Even the Soviet expert can’t believe it. You pilots are the only ones who went up and died. Commander Liu (Yalou) said that we can’t wait. War is about fighting and building while learning from war.

Li Hanqi won, and his classmates in the old aviation school in Northeast China were all ready to try.

Liu Yudi (then the captain of the 1 ST Brigade of the 7 th Regiment of the 3 rd Division of the Volunteer Air Force): Liu Yalou attended the meeting. He pointed to your name, Liu Yudi, Mou Dunkang, Wang Hai and Lin Hu. You guys, can you be like Li Han? Can you get off the plane? At that time, we didn’t speak and didn’t dare to speak, so what did we say at the meeting? Later, after the meeting, we ate and drank together, and two glasses of wine would embolden us. Wine would embolden us. I went to propose a toast to Liu Yalou. I said that Commander Liu and Li Han could get off the plane, so we could fight. As long as we were told to get on, we could get on and get off the plane!

Liu Yudi, a first-class combat hero of the Air Force, set a record of shooting down four enemy planes in an air battle.

Sun Weitao (then Secretary and Translator of Air Force Commander Liu Yalou): How bold is Liu Yudi? When firing at enemy planes, don’t fire at a distance of 600 meters, and fire at a distance of 400 meters in Liu Yudi. The shrapnel exploded in front of my eyes. To that extent, the Soviet instructor was surprised, too brave, too brave. He said it was too brave. If you don’t fight, you will hit it.

Li Han, Wang Hai, Lin Hu, Liu Yudi, Zhang Jihui, Zhao Baotong, Lu Min … The first generation of pilots of the People’s Air Force, with quick occupation, fierce attack and not afraid of death, established the famous "MIG Corridor" with the fearless spirit of "fighting bayonets in the air", that is, the airspace north of Qingchuan River and south of Yalu River. In the 200-mile "MiG Corridor", the air control does not belong to the US military!

Zhao Baotong, the "king of air combat" in the history of the People’s Air Force, shot down 7 American planes and wounded 2 others, creating the highest personal record of volunteers pilots.

Wang Hai, later the fifth commander of the Air Force, led his team to engage in fierce battles with the US Air Force for more than 80 times, shooting down and injuring 29 enemy planes. On December 3, 1952, over the Qingchuan River, Wang Hai led 12 MiG-15s against the 51st Brigade, the ace flying team of the US Air Force, and won with a record of 6: 1.

Wang Hai (then the captain of the 1st Brigade, 9th Regiment, 3rd Division of the Volunteer Air Force): We have a saying in Jiaodong that Lao Tzu is not afraid of death, so don’t pin his head and melon seeds on his belt. As long as he is not afraid of death, you can’t die. The more he is afraid of death, he will die first. That’s what I mean. Right? I just thought, you in the United States are also a person, and we in China are also a person, and we were nurtured and grown up in Mao Zedong Thought at that time, right? Lao Tzu is not afraid of death, and there is nothing, so there is not a coward in my brigade.

On August 2, 2020, 94-year-old General Wang Hai left us. In the last years, he encouraged young pilots like this.

Wang Hai (then the captain of the 1st Brigade, 9th Regiment, 3rd Division of the Volunteer Air Force): Oh, I’m flying into the J -20. I hope young people will fly well!

In the process of learning from the Soviet Air Force and fighting with the US Air Force, China’s Air Force grew up in the War to Resist US Aggression and Aid Korea, and the Vietnam War became stronger. In actual combat, they put forward the tactics of "one domain, multiple layers, four systems", with high and low coordination, step-by-step attack and flexible operation; In November 1951, the 8th Air Division was able to cooperate with the 50th Army of the Volunteers to bomb Dahe Island and carry out joint air-ground landing operations. By the end of the Korean War, China Air Force had 10 fighter aviation divisions and 1 regiment, and 3 bomber aviation brigades participated in the war, shooting down 330 enemy planes and injuring 95 enemy planes. It lost 231 aircraft. By the end of 1953, the People’s Air Force had grown to 28 divisions and 70 regiments, with more than 3,000 aircraft of various types.

As mentioned just now, the first volunteer air force to shoot down the enemy plane of the US military was the heroic pilot Li Han, who came from the famous Air Force 4 Division. This heroic unit fought in the DPRK five times in the War to Resist US Aggression and Aid Korea. In March 1956, it was awarded the honorary title of "China People’s Liberation Army Air Force First Division" by the Central Military Commission. Let’s take a look at the daily training and mission of the young pilots who passed on this heroic unit.

The ace troops of air combat victory continue to defend the air and space security of the motherland.

At 9 o’clock in the morning, a 2-on-2 "air battle" was about to begin. Yao Kai, a super pilot who played on behalf of the Red Party, took off his fighter plane. However, shortly after taking off, the battlefield situation changed.

Yao Kai, Deputy Chief of Staff of an Air Force Aviation Brigade: My wingman has been locked by the opponent, has entered the inescapable zone, and was directly hit by the opponent.

The shooting down of the wingman meant that Yao Kai had to confront two blue fighters at the same time, and it was almost impossible to win in the case of one to two.

With rich experience and tacit cooperation, the wingman made a move before being shot down, which made the situation instantly clear.

Yao Kai, Deputy Chief of Staff of an Air Force Aviation Brigade: Before being shot down, I had lured my opponent within an optimal launching distance. At that time, when I turned around, I fired a missile and shot down my opponent.

The situation of 1-to-2 instantly turned into 1-to-1. After a series of heavy tactical maneuvers, Yao Kai launched the final attack on the blue fighter.

Yao Kai, Deputy Chief of Staff of an Air Force Aviation Brigade: I found one of my best attack windows, fired a missile and shot him down.

Yao Kai, which made the impossible possible, came from China’s first aviation unit, and its predecessor was Air 4 Division, which became famous in World War I in the War to Resist US Aggression and Aid Korea. Since 2014, this unit, which has a special relationship with the War to Resist U.S. Aggression and Aid Korea, has carried out the escort mission of the volunteers’ martyrs’ remains for seven consecutive times.

Yu Changyi, pilot of a brigade of Air Force Aviation: Our unit is the trump card of the War to Resist U.S. Aggression and Aid Korea. On the way to welcome the remains of martyrs back to China, we went through this journey again. My heart was heavy, but I was proud to welcome them home.

Every escort mission is a spiritual baptism for officers and men, and this baptism also gives everyone in this unit a deeper understanding of defending the peace and tranquility of the motherland.

The bright spot on the radar is approaching, and a rapidly approaching foreign fighter plane keeps the warning signal in the cockpit continuous, but Lowe has no intention of retreating.

Luo Wei, a pilot of an air force aviation brigade: Having seen his badge and number clearly, the other plane immediately pressed the slope to us and compressed the interval, which interfered with our tracking and monitoring. I immediately made an S-turn behind his tail and followed him all the time. When the other side found that they couldn’t get rid of me by hovering or pressing the slope, they left our coastline and flew to the high seas.

Safeguard the peace of the motherland in the most dangerous places and defend the air and space security of the motherland in nine days. With the deepening of the strategic transformation of the People’s Air Force, the flying track of this "ace" unit is getting farther and farther, and the list of tasks is getting more and more: the whole system is trans-regional maneuvering, the distant sea police patrol mission, and the plateau live ammunition shooting … The number of "firsts" they have created has been refreshed repeatedly, and these firsts have also witnessed their mission in the capacity building of "actual air force, transformation air force and strategic air force".

Just now, we also mentioned that during the War to Resist U.S. Aggression and Aid Korea, the only joint air-ground landing operation of the Volunteers was to land on Dahe Island. In that year, another heroic unit of the Air Force, the Air Eighth Division, carried out air missions. During the war, less than a year after the establishment of the Air Eighth Division, our first bombing mission was carried out. Now, in the information age, what is their combat effectiveness? Follow the reporter into the air force to bomb a certain aviation regiment.

"Yamato Island Spirit" Inspires Air Force Ace Forces to Win the Sky and Space.

When carrying out the mission of bombing the size and island, the Air Eighth Division experienced the extreme moment of nine minutes of air combat.

Yang Zhukui (87 years old), former pilot of Chinese people’s Volunteer Army Air Eighth Division: When we are alive and our comrades are in a group, it takes nine minutes. Generally, the battle will be solved in one or two minutes in air combat. As an air combat, it takes you more than nine minutes, which is quite long and rare in history.

The Air Force bombed Sun Qichao, a pilot of a certain aviation regiment; 70 years ago, we bombed the heroic deeds of Yamato Island, and in recent years, we went out to the island chain, went out to the West Pacific and patrolled the South China Sea. Now it has become the norm. These are the operational missions of our army in the new era, so I still feel glorious and proud in such an army.

Seventy years ago, this division was not afraid of strong enemies, and defended the country and played a national and military power. Today, defending national sovereignty and interests, the "Yamato Island Spirit" has become more emboldened. On the tarmac of an air force aviation division, H -6K fighters, known as the God of War, nervously and orderly mounted ammunition, and they will go to strange areas thousands of kilometers away to launch live-fire assaults on predetermined targets.

After graduating from college, Song Chuntao has been serving in the fighter plane combat unit, performing many major tasks and flying safely for more than 4,000 hours.

Song Chuntao, head of the air force bombing aviation regiment; Simply hitting a bomb and a certain target is no longer suitable for our current combat environment or a battlefield we will face in the future. This is no longer suitable. It is more a test of our pilots’ integration into the system. I know how to hit, what ability I have, what kind of target I can hit, and when I can’t hit the situation, there are other coordinated troops to help me complete it and make up for my shortcomings to achieve this combat goal.

Sun Luyu, Deputy Head of Air Force Bombing Aviation Corps; For us, taking off is combat, and only when we go up, even if it is simple training, we should regard it as actual combat training to perform this task.

　　It is reported that the Zhejiang pre-school education expert group went to Xinjiang to provide professional guidance through various means such as summit forums, activity exhibitions, and admission (school) guidance, and to teach Zhejiang pre-school education experience.

　　At the Zhejiang-Xinjiang kindergarten curriculum construction summit forum with the theme of "exploring suitable and effective curriculum", Hu Ying, the director of Zhejiang Normal University’s preschool education group, gave a keynote speech on "Exploring the new pattern of kindergarten learning and teaching based on children’s position", and took Song Yun’s scene learning as an example to interpret the innovative measures of "four breaks and four stands" to lay a solid foundation for cultivating children’s learning quality in the future.

　　Hu Ying said that kindergartens should try to build a new scene learning model, giving children the experience of immersive games, so that children can be in a free, autonomous and self-disciplined state when learning scenes, so as to learn voluntarily, spontaneously and introspectively. Hu Ying believes that observation, as a basic skill of kindergarten teachers, is indispensable in curriculum implementation. After observation, teachers should keep tracking and reflect on the whole process of curriculum implementation path, starting with basic reflection, phased reflection, critical reflection and progressive reflection, sorting out the problems encountered step by step, optimizing the curriculum plan, igniting children’s interest in inquiry, and making children’s learning achievements valuable and meaningful.

　　Li Haixia, director of Blue Sky Kindergarten in Keping County, said, "Not long ago, we just went to Zhejiang ‘ Charging ’ In a week, I was warmly received and given everything by the master and the vast number of Zhejiang preschool education colleagues, which not only gained growth, but also enhanced the friendship between preschool teachers in the two places. "

　　"A road to aid Xinjiang will help Xinjiang for a lifetime." Hu Ying said that the next step will continue to promote mutual visits and exchanges between the two places, explore the practical "scene learning" education model together, promote the in-depth development of preschool education in Aksu, and lay a solid foundation for meeting the beautiful needs of Aksu people for education.

China football, why is it ＂hot＂ again recently？

BEIJING, Beijing, May 27 (Reporter Bian Liqun) "Shanghai Shenhua goalkeeper Ma Zhen committed violent acts and punched the opponent’s player in the face. He was suspended for 5 games and fined 50,000 yuan; Rodriguez, a foreign aid from Meizhou Hakka, carried out non-sports behavior and used insulting gestures to the opposing players. He was suspended for 4 games and fined RMB40,000. "

On the evening of 26th, China Football Association issued another heavy ticket. This is already the second consecutive round of the Super League, and two players have been severely punished for violence on the field.

Recently, football in China is full of anger, and in addition, the referee is insulted in the game and accused by social media. Since May, the China Football Association has issued as many as 21 tickets, most of which are concentrated in the past half month.

The fire can’t be suppressed again.

The league has returned to the home and away games, and the fans have returned to the stadium. This season, the Super League is very popular. However, recently, there has been a lot of anger.

Of course, every season, there will inevitably be angry scenes. At the beginning of last season, just after two rounds of competition, the Super League created nine red cards and five tickets.

In contrast, this season, it is an improvement to enter the third node of the league and get frequent fines.

Since the fifth round, the fire in the Super League has gradually started. Sunic, the foreign aid of Henan team, pushed down Fang Hao, a teenager from Beijing Guoan, and was suspended for five games by China Football Association, and fined 50,000 yuan.

In the same round of competition, Fan Bing, an official of Nantong Zhiyun Team, was banned from entering the competition stadium for one game and fined RMB10,000 by the Football Association for publishing the contents of questioning the referee in the WeChat circle of friends.

Coincidentally, Xie Hui, the coach of Dalian People’s Team, was also banned from entering the competition stadium for one game and fined RMB 10,000 for publishing the contents of the penalty dispute on social media.

As Nantong Zhiyun sent a long article in response to the Football Association’s fine on May 16th, the fire reached a new height.

"The facts on which the penalty decision is based are unclear and are not within the jurisdiction of the Football Association Disciplinary Committee, and the applicable rules are inappropriate; Moreover, although the punishment decision shows that there is a’ description of the parties’ by applying the template, in fact, it did not give our club or Fan Bing any opportunity to communicate, explain and defend themselves, and never held an interview meeting or hearing under the rules, lacking due process. "

"If such’ punishment decisions’ that lack legal basis and express personal opinions are allowed to flood, it will inevitably lead to illegal restrictions on the legitimate freedom of expression of football players and lead to a chilling effect."

Until now, the China Football Association has not responded to this. And a wave of unrest, a wave of rise again.

In the match between Tianjin Jinmen Tiger and Shandong Taishan Mountain on May 19th, Jia Desong, a foreign aid of Taishan Team, punched Beric, a foreign aid of Tianjin Jinmen Tiger, and the latter was injured. Jia Desong was finally banned for five games by the China Football Association and fined 50,000 yuan.

In the same round of competition between Wuhan Sanzhen and Chengdu Rongcheng, Aziz, a foreign aid from the three towns, trampled on his opponent’s leg and was banned for four games and fined 40,000 yuan.

Next, Shanghai Shenhua goalkeeper Ma Zhen and Meizhou Hakka foreign aid Rodrigo.

Why are you so angry?

Recently, the violence in China football field has been concentrated, which has to cause a question: Why are people so angry?

This season’s return to the home and away Super League, although the star flavor is insufficient after the loss of big-name stars, the game is still quite fierce.

To a certain extent, some of the anger also comes from this. Under the competition for every inch of land on the court, coupled with the blessing of the players’ own hormones in the game, irrational behavior is prone to occur.

However, combing down, the source of a lot of anger comes from some penalties.

For example, Fan Bing, an official of Nantong Zhiyun, and Xie Hui, the coach of Dalian, made speeches on social media, all of which were aimed at the referee’s penalty.

In the match between Tianjin Jinmenhu and Shandong Taishan, the players of the two teams have accumulated anger for a long time. Before Jia Desong’s boxing behavior, the fighting action has gone beyond the normal range. Unfortunately, the referee on duty failed to control the field well, which indirectly led to a large-scale conflict at the end of the game. All kinds of chaos have buried the original excitement of this goal war.

Sunic, a foreign aid from Henan province, and Aziz, a foreign aid from three towns in Wuhan, were given additional punishment for their violent behavior, but in the game, the two referees on duty only showed them yellow cards.

The Wuhan Three Towns team punished Aziz for one dollar and responded to the ticket in disguise.

Another big source of anger is the intensive schedule. Since the start of the game on April 15th, the Chinese Super League has played 9 rounds in more than one month, with each team playing once every 4 days on average.

Under the long-term consumption of double matches in a week, the players are inevitably tired of fighting, which further increases their anger.

Sparse fire can reduce fire.

Objective factors, such as the intensive schedule and the referee’s ruling level, cannot be changed in a short time. Therefore, the way of suppressing fire, which is similar to punishing improper remarks, can not reduce the fire well, but is easy to be swallowed up by fire.

Therefore, Nantong Zhiyun, Wuhan Sanzhen and other clubs responded fiercely, and the behavior of club officials abusing referees on the court and questioning referees on social media off the court became more and more concentrated.

Fans in the stands and on social media are also angry.

For the current football in China, communication needs to be strengthened, and all parties need to reduce the fire.

In fact, in the 2021 season, the Super League used the mechanism of publicly responding to controversial penalties, but it did not last long, and such responses disappeared.

In addition, some fans suggested that it is possible to reconsider choosing an international referee in some 6-point battles related to championship or relegation.

Although this move may not necessarily put an end to the phenomenon of questioning the referee and the misjudgment and omission in the court, it can still alleviate the anger caused by various trust crises.

In any case, it is really precious that the league resumes home and away games, fans return to the stadium, and some stadiums even have a hard-to-find ticket. Football practitioners in China should cherish this fire, not anger. (End)
