2. Subject of the text: The text tells that when I was a child, "I" thought that everything that could make a sound was a living creature, so I was extremely curious about my father's performance and thought that there was a "little scorpion" in what my father said. Through such a childish and interesting thing, it shows that my childhood "I" has a strong curiosity about things, that "I" is a child who is good at observing and thinking, and inspires students to cultivate their habit of observing and thinking and the spirit of continuous exploration from an early age.

In the first part (paragraphs 1 to 9), when I was a child, I thought that everything that could make a sound was a living creature, so I guessed that there were creatures in my father's watch; Part II (paragraphs 10 to 19): It is written that my father opened the watch cover to let me see the world inside and told me that there was a little scorpion inside, so I couldn't move. His words confirmed my guess; The third part (paragraphs 20 to 2 1): It took a long time to write "I", and everyone was talking about the scorpion on my father's face.
