Friendly greetings
The first thing the teacher said in class was "Good morning, class." A smile and a gentle greeting immediately brought the distance between teachers and students closer.
Respect students' personality
The core of teachers' polite language always lies in respecting students' personality. Speak kindly to students, with moderate and measured tone, soft and pleasant tone and sincere feelings.
Friendly attitude
Have a friendly attitude towards students, and always put yourself in the other's shoes when talking with students, so that students can realize from the bottom of their hearts that everything a teacher does is for the good and development of students.
First think and then speak.
A teacher must speak elegantly, think twice before you act, and speak carefully. Never use harsh and sarcastic words to hurt students' self-esteem, let alone insult them.
