【正文】 as to deepen the understanding of basic physical concepts and laws such as mass, weight and Newton’s law. Microgravity environment is difficult to obtain on the earth. If it cannot be pleted on the ground, it is moved to space. The experimental phenomenon will be more direct and intuitive without using inference and other methods. Live broadcast of such scientific research is worth looking forward to.　　Wang Yaping is in space, facing the earth and teaching to people on earth. He is the first Chinese space teacher, demonstrating the demeanor and style of a space power.　　Wang Yaping said: “in the face of the vast universe, we are also students. I look forward to feeling and exploring the magical and wonderful space with the majority of young friends to obtain knowledge and happiness.” The universe is vast. The universe is magical, plex and changeable. Many mysteries in the universe are worth exploring. This is the attitude of science.　　Aerospace technology has always been an emerging field that any country must pay attention to. It plays a very important role in our exploration of space and the unknown. In today’s society, air control has bee very popular, so the deeper level is the right to space. For example, the United States, a powerful country, took the lead in landing on the moon, and then he united with other countries to divide areas on the moon. He said that whoever occupied the moon would have the right to mine in the future, so our aerospace technology should not lag behind, otherwise we will gradually lag behind in the next 100 years, Therefore, aerospace technology and aerospace hobby will be the most important direction of our new generation.　　The first contact with aerospace knowledge was in the large class of kindergarten. That day, the teacher pasted a newspaper on the wall. There was a rocket actually Shenzhou 6, and two people actually Fei Junlong and Nie Haisheng. Hearing the teacher’s vivid explanation, I got a general idea and felt proud. Suddenly, I found that there was no woman. At that time, I thought: if only I could be the first female astronaut in China! From then on, I went to primary school with such a dream. I was proud to say to one of my classmates that I would bee China’s first female astronaut in the future. He listened and showed envious eyes. At that time, I was very proud. I thought it was too easy to be an astronaut! In the third grade, I gradually learned some knowledge about aerospace. Only then did I know that being an astronaut is not so simple. It requires not only knowledge, good health, but also good psychological quality in fact, I didn’t understand what psychological quality is at that time, but just vaguely felt that it is a part of good health.　　Although I know it is unrealistic for me to bee an aerospace astronaut, I can work underground for them, such as ground service and research. We can study some safer and more efficient spaceships or space equipment on the ground, or we can take a look at their vital signs and various information security technologies in the underground mand center and the middle space astronauts. So, in order to realize this dream, I am constantly learning and participating in some science and technology exhibitions. In order to know more about this knowledge and pave the way for my future dream.　　On December 2, 2021, another good news came! China Manned Space Engineering Office announced that in order to give full play to the prehensive benefits of China’s space station, China’s first space science popularization education brand “Tiangong classroom” will be officially launched. The first space teaching activity of China’s space station will be broadcast live to the world in the near future.　　I am very excited to see this news, because I can see a series of wonderful phenomena of object motion in the space microgravity environment. This reminds me of the space lecture in 2013.　　In only 40 minutes, the astronauts only used five simple experiments to make us better understand the changes of objects and the principle of their changes in the weightless environment. There are water film experiment and gyro experiment... Let me know that I can do many incredible things in the weightless environment. Among them, I am most interested in water polo experiment!
