I firmly believe that everyone in the world loves their mother. So am I. My mother is a ordinary teacher. She always works hard, just as other mothers do every day. In fact, she isn’t good health. She had been suffering from arthritis(关节炎)for many years. Despite of this, she never stops working or giving up hope. I still remember the day when my mother accepted a card of congratulations for Teachers’ 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 for my mother.
