Emily stared at the ants for a long time. She broke a piece of sugar and threw it on the ground. Not long after, a group of ants came over and worked hard to move it, one after another. The black ants formed a small line. If one was not careful, one could trample them to death. The ants were small and weak.
A person cast a shadow. Emily did not move. She only heard a man's low and pleasant voice. "What are you looking at so attentively?"
Emily pointed at the ants and said, "I think they should be a family. These two are father and mother. This is brother, and this is sister. They are uncle, aunt, and grandparents. Look at them. They are all carrying sugar on their backs. They are trying hard to take the sugar home. There are younger brothers and younger sisters at home. They are hungry and waiting for food."
