How to write a 300-word composition by someone I know very well?

I know many people, but the person I know best is my mother, and I know her very well.

My mother is of medium height. She has black hair, big eyes and a glib mouth. My mother is eccentric. When I was good, she was as gentle as a sheep. I am like a bison when I do something wrong or don't study hard, and I have a particularly bad temper. Mother likes eating shrimp best and drinking best. She also likes playing mahjong on the computer and looking up information online. Mother studies hard and often works day and night. Mom said: "It is also a great enjoyment of life to prepare lessons while eating melon seeds at home!" So what!

My mother is a biology teacher in middle school. She often teaches me biology, probably because of heredity. I also love biology. Under the influence of my mother, I know a lot about biology. Therefore, I am a doctor of biology in my class. On one occasion, the teacher wanted to teach a text entitled "Kingfisher". She told us to go home and look for information. I turned to my mother for help as soon as I got home. Mother agreed, so she said plausibly, "Kingfisher Cantonese call it Diaolang. The largest and most widely distributed kingfishers are Eurasian kingfishers ... "I heard what my mother said as if I knew all about kingfishers, clapping my hands and praising my mother again and again, and I admired her very much.

My mother is very kind to me. Whenever I have a question, she helps me answer it. She is also my friend for life. My mother is both my good mother and my good teacher, because she has given me sincere love and endless knowledge.
