A good book is the best of friends, the same today and forever.

一本好书，相伴一生。

I'm Sarah. Thirty years ago, I was a pupil. My dad was a teacher. He taught Maths. I was in his class. I studied very hard. I was a good pupil. Now, my dad doesn't work. I am a teacher in a school. I teach English, because I like English. And I am writing a book in English. The children in my class love English very much and study well.
