    In my school life, a most unforgettable person is my math teacher. Not only did she helped us in class but also after class. I still remember the time that I got a “B” in the final exam. I liked math best and the teacher took pride in me all the time. However, I failed. I felt so disappointing that I lost my energy and patience. Then one day, I happened meet her in the street, and my face turned red right away. She told me not to give up and encourage me to work much more harder. Later, he offered me a great many suggestion on learning math. In addition, she cared for my feelings. Under her help, I made great progress.
