All of my students think I’m a good teacher．I _________ in the school since 1999．I am always nice to my students．I often_________ them with their school work．So I__________ as their best friend．They love me very much and they often do something nice for me．One day before Teachers’ Day, some of my students __________ me some presents．When they gave me the presents, they said “Thank you for teaching us so well and we _________ harder than before.” How nice my students are!
