"Dad, what's the smallest bird in the world?" I asked. Dad said, "it's a hummingbird, and it can fly backwards.". Dad's knowledge is boundless, like an encyclopedia. No matter what questions I ask Dad, he always gives me answers. Dad has a wide range of knowledge.
Why does Dad have such a wide range of knowledge? Because he likes reading books, he never read comic books and novels, but literature, history, natural geography, science...... So he has a wide range of knowledge. Dad's books are everywhere, on the table, on the floor, in the bedroom, on the sofa, and even in the bathroom. Dad said that he could read at any time, so he has a wide range of knowledge.
Dad, I must read more books than you!
