How time flies! I will graduate from middle school in two month. I'm eager to shre my happiness and sadness with you. Thinking back, I alwasy remembered the moving moment. One day, when I stepped into the classrom, my classmate told me that Mr.Sun, our math teacher, couldn't come to school because of a terrible traffic accident. I was so worried about him that I went to the hospital to visit him. Although he got badly hurt, he smiled to me as usual. Sucn a beautiful smile made me warm and moved. Mr.Sun is the teacher who not only gives me knowledge but also encourages me to be positive all the time. I will never forget his smiles. 纯手打,希望能够帮到你!
