I believe that everyone in the world loves their mother. So am I. My mother is  a  ordinary  teacher.  She works  hard at  school,  just as other mothers do every day. In fact, she isn’t good health. She have been suffering from arthritis(关节炎) for  many years. In spite of this, she never stops working or giving up hope. I still remember the day and when my mother received a card of congratulations for Teacher’s Day from her director. The card was read “Thank you for your hard works; Happy Teacher’s Day to you!” At that moment, I was so moving that tears came to my eyes. I am proud of my mother because she is my best teacher as good as my mother.
