故事简介：我的数学老师是一个聪明又有趣的人。我第一次遇到她是在大学的数学课上。她非常喜欢
我，她专注于学生。不像其他老师，她总是有很多有趣的教学点子，比如如何估算一个寿司店的利润。

My mathematics teacher, Jane, is very interesting and smart although she was 50 years old. She is 5 feet 5, has a bit fat body and a great complexion. Her face is a bit round, which makes her look amiable.
I first met her in a mathematics lecture, when I was in the first year of the university. She is a lovely woman who, if I remember well, really likes me. She is very humorous and dedicated  towards her students, and that is probably one of the reasons why I grow to love mathematics. During the lectures in a spacious room, she often introduces us to solve problems with basic operations, like addition and multiplication.

She always has interesting ideas, and she often explains difficult theories in plain language, keeps a bag of candies and would give candy to anyone who answered challenging questions. Compared with other teachers, her ideas about teaching are much more interesting. She always show us how to think about simple real-life problems using mathematics. Various daily examples demonstrated during the lecture attract us a lot, making lectures more interesting. For example, counting people in rush hour is an excellent way to evaluate the profit of a local Sushi store.
