When i was a child ,an idea occurred to me that i want to become a nurse .mum asked why ,i answered happily "being a nurse ,i can assist with the doctor to save patients' life.what a grateful job the nurse is !so ,i dream of being a nurse everyday.
one day ,when i cross the street ,i saw an old lady felt on the ground ,hurt badly .i was in a hurry to make her stand up ,then i called 120 .later,the first aid car came and pick her up to the hospital ,i was proud of myself of helping others .from then on ,i prefer being a nurse to make contributions to others .
