How does dad like to write a composition?

"Dad is an astronomer." Dad has been an astronomer since he was a child, but for various reasons, he has never been able to do so. Dad still sticks to this hobby after he joined the work. As long as I have spare money, I will buy some astronomy books. There are many books about astronomy at home. Mom's boss is unhappy and often nags: "Look, all the money at home makes you buy some useless things. Can you still eat and drink?" Dad doesn't think so. Maybe it was infected by my father. I also like astronomy since I was a child. Dad bought an astronomical telescope. We often watch the astronomical phenomena at night, the craters on the moon, the halo on Saturn, the great red spot on Jupiter and the big tail of comets ... We are very curious. While explaining astronomy to me, my father told me stories about astronomers at home and abroad. Zhang Heng, Guo Shoujing, Wan Hu, Kepler, Galileo, Newton ... have all become familiar names. Their stories are very attractive, and I am fascinated by them. From the mystery of celestial bodies to the discovery of gravity, my father talked endlessly, and I listened with relish. I didn't expect my father to be so knowledgeable. I can't help secretly trying. I must study hard and become a scientist in the future and make contributions to the country.
