Mary Smith is my aunt, my mother's sister. But I don't call her aunt, I call her Mary. She is a young god-looking woman. I don't know how old she is because that is a secret（秘密）But I know her birthday is on June 29th.

She is an English teacher. In her class, she is very serious（认真）. Her students need to answer her questions in English. She often plays games with her students in class, so her class is always interesting.

After class, she is god with her students. They are good friends. Sometimes she buys fruit for them. They all like her and her class.

Do you think Mary is a good teacher?
