When it comes to "building a happy China", students may say, "We are primary school students, and the construction of the country is a big problem. There are adults on it, why don't they just build it? " Some people may say; "I don't have the ability to build." This is completely wrong. In fact, we primary school students can also work hard to build a happy China.

Let me give an example! Everyone knows about scientist Qian Xuesen, right? He has made great contributions to the people of China and even the whole world. In his youth, Qian Xuesen went to the United States to study. He has profound attainments in missile science. When the Japanese war of aggression against China broke out, he was ready to return to China, but the United States tried its best to retain him to work for the United States. However, Qian Xuesen has made up his mind not to make a weapon for the United States, draw a drawing and try his best to return to China. The United States has no choice but to let it go.

Soon after he returned to China, he joined the * * * production party and made many new missiles. After the founding of New China, he and many inventors created "two bombs and one satellite", namely the atomic bomb, the hydrogen bomb and the Chang 'e-1 missile satellite, in order to strengthen China's border defense capability. He always said: "My surname is Qian, I don't love money, I only love my motherland." Qian Xuesen died on 20 1 1. It can be said that he has been working hard to build a safe and happy China all his life. We should learn from him and build a happy China together.

Maybe some students will say, "I really want to build a happy China, but I don't know where to start?" I can't think of big ideas, and I can't think of small ideas. But do you remember what I just said? Every move we make can make efforts to build a happy China. Although we can't make great achievements like a great man like Qian Xuesen, we can make small contributions! Although these forces are small, many a mickle makes a mickle, and they can also become great. Such as protecting and saving water and electricity.

According to statistics, the people of the whole country only need to turn off a tap and press the turn-off button of an electrical appliance every day, and the electricity saved can be used by the people in the three northeastern provinces. When it comes to saving water, we can keep the face washing water and rice washing water for secondary use to water flowers and flush toilets. Save electricity, don't turn on the lights during the day, use electric fans and air conditioners as little as possible, watch TV at night, and don't let TV stand by all night ... In this way, we can save some electricity and water in our country, which is a contribution to building a happy China.

Finally, I ask you to join hands and contribute to the construction of a happy China!
