Students need advice through their life. Teachers are wise enough to offer advise because they have had enough experience and knowledge. Since, students need teachers who have enough advise, teachers receive respect from students.
For instance, when I was a little child, I learned dance. I often asked dance’s teacher not just dance but also my life’s issue. Thereby, I obtained solution. From that time, I respected teacher.

A -  Students still have to learn from teachers. Teachers are leaders in education. from the educational aspect, since students have to learn academic education, teacher still receive respect from students.
 
For example, when I was a high school, chemistry teacher and I discussed about chemistry issue. At that time, the teacher seem like she was ignoring students. As a student, I felt depressed. thus(therefore) I lost interest in chemistry. Losing interest meant that there was the distance between teacher and me. As a result it caused bad academic record. I recognized that teacher could influence on academic course because teacher was academical leader.
