The word "air defense" has never been touched in my mind, and I don't know its importance. Because I live in a stable era, there is no war and no suffering, so I cannot understand the importance of air defense. But when I finished reading the book "Civil Air Defense", I realized: Oh! It turns out that air defense is so important, symbolizing the prosperity of a country and defending the dignity of a country.

As the name implies, human life air defense refers to the action of preventing enemy air strikes and jointly eliminating air strikes, referred to as civil air defense. Civil defense is a combination of wartime air defense and peacetime disaster relief, which is implemented by the people and becomes civil defense. Civil Defence is the core part of China's national defense, an important factor to promote the development of modernization, and an important cause in which all the people participate. Because air defense is a task that needs to be prepared at all times, "long-term preparation, key construction, and combination of peacetime and wartime" is a three-point project of air defense.

According to China's civil air defense regulations, the task of civil air defense is to mobilize and organize people to take protective measures according to the characteristics of modern warfare, to resist enemy air strikes, to protect people's lives, to avoid or reduce national economic losses, and to preserve war potential. Civil air defense must implement the construction policy of "overall planning, highlighting key points, combining peacetime and wartime, and putting quality first". It can be seen that civil air defense is an implementation plan that our country attaches great importance to, and it can bring peace and tranquility to our people.

Civil air defense is a long-term combat readiness task, because as long as imperialism and hegemony exist, the danger of war will not disappear. So we can't let the moment of peace paralyze our thinking, and the people can't stop preparing for war. Due to the development of modern science and technology, the lethality of weapons is increasing, and the harm to residents in future wars will inevitably become more and more serious. Therefore, under the conditions of modern war, strengthening civil air defense construction is the need of today's nuclear age and has important strategic significance. So we should be prepared for danger in times of peace.

Now, I believe that as long as we cooperate with the national civil air defense construction. In the near future, our motherland must be the most powerful. We can't forget the shame, blood and tears in War of Resistance against Japanese Aggression, which is the price of our blood, and also the difficulties and obstacles when we rebuild the new China with our flesh and blood. Now, we should prepare for the future of our country in peacetime, so that we can be prepared.

When I closed the book, the word "civil air defense" had already penetrated into my heart and I couldn't shake it for a long time. For the future of our motherland, and to reach the top of the world, we should study hard and be small masters of our country in the future. We should also keep innovating, keep fit and make our motherland stand on the top of the world. I firmly believe that the people's air defense association will be paid more and more attention by the masses, and the motherland will become more and more prosperous and developed.
