You should say:
- how you know the person

- how long you have known this person and explain why you respect this person.
and explain why you respect this person.
The person I respect most is the physics teacher in my middle school who had a special individuality. His name was Mr Zhang. He was over 50 then, he had a large bright eyes with a pair of glasses, and there was a bald spot on the top of his head. He always seemed to be thinking about something when walking on the road.
He was extremely knowledgeable. When he taught us, he always made many references to different physicists. Unlike other physics teachers, he never treat physics as maths that always put everything into formula to calculate. He frequently gave us articulate speeches that the physics was the gymnastics for the brain, which inspired my enthusiasm to learn it well. He taught us physics for three years, which made me really fancy this subject all my life long.
Mr Zhang was very dedicated to his teaching. He always prepared his lessons well, and tried various methods to attract students’ attention. He once wore the shirt of Real Madrid in class to arouse our enthusiasm. I believed he was really respectable in his ordinary job.
