二、阅读短文，选择正确答案。
Do you remember the 4th“Tiangong Classroom”? On September 21, 2023, Shenzhou－16 taikonauts Jing Haipeng, Zhu Yangzhu and Gui Haichao gave a lesson in China’s space station.
First, they told us about their life and work inside the space station. They said, “We get up early every day. We wash our faces with a wet cloth and brush our teeth with a special toothpaste. We do sports and grow vegetables too.”
Then they showed us the Mengtian Lab. Later, the most fun part came: the round flame test (球形火焰实验). In space, a candle’s flame turned into a blue ball! How magical it was! They also asked young viewers to do experiments along with them because they wanted to make the lesson more interesting and let kids learn from doing experiments. Some kids asked about the flame, and the taikonauts explained (解释) it clearly.
We learned a lot from this super cool lesson!
