Hello! First of all, I'm sorry that I took the liberty to call you "teacher" because I listened to your lecture carefully in the space. This course aroused my strong interest in science; This course has increased my confidence and strength in studying hard; This class makes me know more about the mystery and greatness of the universe.
This morning, I was very excited to learn that you, Uncle Haisheng and Uncle Guang Xiao have returned successfully! How I want to fly to your side, see you, hold your hand and listen to your story about manned spacecraft. During the fifteen days of space life, you and your two uncles have done so many experiments, experienced severe challenges and tests, and accumulated valuable wealth for the development of China's space industry. I really admire you!
Mr. Yaping, you just got back. I don't want to bother you too much. However, there is a problem that has been bothering me for several days, that is, where is the garbage generated by your work and life in space and how to deal with it? Before you leave, I learned from TV that there are garbage collection bags on both sides of the working cabin, which can be put in at any time. However, what kind of bag is this, how much garbage can it hold, and will it flow into space? I have always been curious. I hope Mr. Yaping can give me some advice.
I want to be an environmental messenger, telling my classmates about the environmental protection concept and advanced technology in space and passing it on to everyone. Let's join hands with everyone to protect our homeland, so that smog will not invade, earthquakes and tsunamis will not happen again, and adults and children will live in the beautiful China with sky blue, water green and fresh air!
Teacher Yaping, let's call it a day and look forward to your early reply.
Sincerely bless you!
