(ale kto? pies? kot? musisz napisac) should evaluate students equally. The teacher should be 'favorable for' (to jest zle) students, 'which' (to jest calkocicie zle slowo, tutaj musisz potwierdzic ze to wlasnie ma waznosc, ale nie tak jak ty to napisalas) can affect the good 'relations' (nie, slowo 'relationship') between students and the teacher. An important feature of the teacher is 'too patient' (co? piszesz ze nauczyciele maja za duzo ...to zdanie przekazuje calkowicie cos innego nic masz na mysli)( A very important feature of the teacher should be a sense of humor, because with such a teacher (ale kto? nieznajomy kolega?) 'is working better' (to jest zle, napisz to biernie)
