Tìm dẫn chứng giúp em ạ. Long ago a lot of people thought the moon was a god. Other people thought it was just a light in the sky. And others thought it was a big ball of cheese. The telescopes were made. And men saw that the moon was really another world. They wondered what it was like. They dreamed of going there. On July 20, 1969 that dream came true. Two American men landed on the moon. Their names were Neil Armstrong and Edwin Aldrin. The first thing the men found was that the moon was covered with dust. The dust was so thick that the men left footprints where they walked. Those were the first marks a living thing had ever made on the moon. And they could stay there for years and years. There is no wind or rain to wipe them off. The two men walked on the moon for hours. They picked up rocks to bring back to earth for study. They dug up dirt to bring back. They set up machines to find out things people wanted to know. Then they climbed back into their moon landing craft to begin their long trip back to the earth. Behind them they left the plains and tall mountains of the moon. They left the machines they had set up and they left footprints that may last forever. 1. What is the story about? A.
