Looking back at the modern history of the motherland, it was dark, and our Chinese nation suffered a lot and suffered humiliation, which is rare in world history. Since the Opium War 1840, China's dark history has come, but the people of China have never given in, kept fighting in humiliation and suffering, shed tears and shed blood, finally mastered their own destiny and started the great process of building their own country. This spirit needs us to pass on. For example, in the documentary "Broken Knife", in the "War to Resist US Aggression and Aid Korea", China volunteers were all dressed in light clothes and their weapons were very backward, but they confronted enemy planes and artillery in the heavy snow. They finally won, and they won with this perseverance and belief, which fully demonstrated the great national spirit with patriotism as the core.

At present, the technology of the motherland is developing constantly, such as the developed aviation industry and nuclear industry in China, as well as artificial satellites, the manned submarine "Jiaolong" diving for 7 kilometers in the deep sea, and computers with more than one trillion times per second, etc. Our great motherland is getting richer and richer day by day.

Today, standing at a new historical starting point, we should continue to pave the way for the future motherland and support the hope of the nation with actions. First of all, we should improve our knowledge, broaden our horizons and strive to be a useful person to society, which is also our responsibility. At the same time, we should always know the basic national conditions of China.

We should aspire to be a patriotic youth. Only by remembering history can we remember: "backwardness will be beaten and development will be self-improvement"; We should base ourselves on the present and work hard in a down-to-earth manner; We should look to the future and never give up the future of our motherland.
