Today, the topic of my speech is "The motherland is in my heart". Now, with the development of science and technology in China, we all live a happy well-off life. But you know what? In 1950s, China was looked down upon by people. It has no great scientific achievements, and its science and technology cannot develop. However, some intellectuals who returned from studying abroad brought a fundamental turning point to China's fate. They straightened China's back.

Deng Jiaxian is one of these international students. At that time, he heard about the state of science and technology in China, gave up his doctorate and decided to return to China to contribute his strength, because he knew that he was a child of China and a descendant of the Chinese people!

He returned to China and participated in the development of the atomic bomb. Deng Jiaxian is not afraid of difficulties, and often leads staff to work in the front. He personally went to the Gobi desert where the yellow sand filled the sky to collect books, and even risked being irradiated to supervise the production of atomic bombs. Finally, with the joint efforts of him and everyone, the atomic bomb test exploded successfully! Subsequently, Deng Jiaxian successfully developed the hydrogen bomb and the Dongfanghong satellite at an alarming rate. Grandpa Deng Xiaoping mentioned Deng Jiaxian and said, "Two bombs are his medals, and China is proud of him!"

Among these intellectuals, there are still many unknown people who work in the front line and forget to eat or sleep. What are they working so hard for?

China has such beautiful rivers and mountains, such a long history and such a splendid culture. They just want to keep the motherland from being insulted and laughed at by foreigners.

Which is not magnificent, the Forbidden City or the Great Wall?

Which is not beautiful and magnificent, Mount Tai or Huangshan?

Paper making or gunpowder, which is not our pride in China?

When the bright red five-star red flag Ran Ran rises, we will all think of those patriotic intellectuals. It is this sentence that has become their motivation-I come from China and I love China!
