雅思口语P2 Describe a polite person you know (文字版)

The polite person in my mind is a professor in university, actually I have been in his class for 2 years, very impressive. You know, he looks a bit old, at the age of 60 or something, usually put a smile of joy on face. I majored in history, apparently lots of questions were waiting for me each day. More importantly, he would answer all the questions from the students, sometimes in person, sometimes through the Internet, like email for example. You know, every single day, a formal suit is always with him, which makes him feel quite confident and gorgeous, for real. You know, I talked to him a couple of times, he must have good temper I suppose. He tried to explain something one or two to me patiently, time and time again. I thought that this point was hard to get, since patience is the greatest love to someone and something, those people who want great career need the patience, undoubtedly. For me, if you are patient at your work and life, then you must be a polite person. So, that is it.
