    High school is a time that we may meet many good teachers. When I was in Senior One, I met a teacher who name is John. He was very old, and taught us chemistry well. He tried his best to make her classes lively. He usually made good preparation for the lessons and was strict with us, too. Whenever we made mistakes in our homework, he would ask us to correcting them. I was used to be poor in chemistry. He often helps me with my studies very patient. Because of his help, I made rapid progress and caught up with the class. He was always very kind to every student. As experienced teacher, he was respected and loved by all the students.
