In high school, my the worst subject just math. I hated it vastly, especial trigonometry, because there are many problems which need to think in logic. Plus I was so lazy to make much practices that my grades had been so terrible.
At large, everyone wanted to give me up because of my terrible condition. But my math teacher, Mr Li, still want to try his best to change me. He told me many interesting ways to solve problems in life, which let me learn much. Maybe math was not as boring as I imagined. Hence, I started to study it hard for changing my terrible past. I know the importance of math. The math to one what water is to fish.
At length, I got a good grade. I was very grateful for my math teacher, I knew my debt to him is beyond to measure.
