Look back at the title “Space: The Final Frontier”, what’s your understanding of it Share your ideas with the whole class.
I don’t think the space is the final field of exploration because on the earth there are still more places to be explored by people, such as the original forests, the remoted mountainous areas, the deep ocean, and the polar regions. There are so many unknown places, and the space is just one of them.
