雅思口语P2 Describe a person who is good at his or her job(文字版）

Mention about the topic, someone who I think can do well in his job is my university professor Jason. He who teaches us French is pretty good at his job. You know, I got to know this special person a couple of years ago when I was a freshman on campus, he looks rather tall, short hair, which made him feel quite confident. He was not the type of teacher who liked to talk a lot, but very patient after the class. You know, we had his Emial, when we met some problems of study or couldn't understand something of the class, we would ask for help through the Email. The point was that I could get the reply quite soon every single time, maybe in 2 hours, sometimes at midnight, occasionally early in the morning. He was very careful with his work, I mean he wouldn't make any mistakes in the class or after the curriculums. I didn't know why he could do this. It was not an easy work. The other day I had the answer from him, I just like what I am doing, he said so. He loves teaching by the way. So, Jason is the one who I look up to. That is it.
