On the one of the lessons of methodology of foreign language  I  have learned about some  rules for teacher.They are include such rules as to clean a board at the end of the lesson. It always must be ready for the next lesson.Then  the teacher should start and finish a   lesson on time! You have to return borrowed things. It can be need teacher for the next  lesson or preparing tests or so on.You should use computers  and class's  equipment  neatly , don't break them, and if something broke, you must report about it. Your   dress style should be official.    
     It was rules   that  I remembered and of course I will  use   them.
