If you used to be a student, I'm sure that you have to have a good teacher in your mind. For me, My good teacher is my english teacher. Her name is Jessica, she is a American teacher. I was impressed by her character. If your teacher is hard, Jessica is easy. She always smile with her student and help us improve our grammar and vocabulary. In addition, she know French, Japanese and Chinese. It's a special impression for me because that's the first time I was taught by a teacher who know so many foreign languages.
Nowaday, she doesn't teach me, but in my mind, she's still a best teacher.
"Jessica, I wish you had all best things"
