The teacher is imparting knowledge to the students in class. This process is a very serious matter, and we should respect it. When we are in class, the students are all listening attentively, and the teacher is also trying to teach. This process is to impart knowledge. If a teacher smokes in such a solemn environment, it is a very disrespectful behavior to knowledge and students, and he must not smoke in class. 2. University professor is an influential profession, which will teach bad students.
Speaking of university professors, everyone is very respectful, because a person can become a university professor, first of all, he is a very excellent university graduate, and secondly, he is a very excellent teacher, so university professors are a very influential profession. If a university professor smokes in class, the students below are easy to imitate, so it is easy to lead bad students. Being a university professor is a demanding occupation.
As a university professor, he is a high-end talent and has received a lot of praise. University professors should set an example and be strict with themselves. They should not smoke in class. Doing so is not in line with your status as a high-end talent, which will lower people's expectations of university professors.
In a word, I don't think university professors should smoke in class, because first of all, smoking in class is a serious matter. They don't respect knowledge or students. Secondly, university professors, as high-end talents, should set an example and not smoke. Besides, university professors can easily teach bad students to smoke.
