Once upon a time, there was a little boy named Tom. He lived in a small house with his mom and dad. Tom had a big wish. He wanted to understand why the sun was so hot and bright.
One day, Tom went to the park with his friend, Sam. They saw a big tree with harsh branches. Tom asked Sam, "Do you understand why the sun is so hot?" Sam said, "I don't know, but I wish I did."
Tom and Sam decided to ask their teacher, Miss Lily, about the sun. Miss Lily told them, "The sun is hot because it has fire inside. It gives us light and warmth." Tom was happy that he finally understood. Now, he could share his new knowledge with everyone.
