短文改錯(cuò)Last summer vacation,I worked as avolunteer in ahospital,which Imet a little girl,Xiaoxiao,who is only seven years old,Ahe just had an operation on her leg but had to stay in the bed for some time.I was amazed by her courage because she never cried even ad shewas suffering a lot of pain.I once noticed her helping a little boy which parents couldn't come tu see him that day.She was sharing her sweets and toys for the boy and telling stories to calm her down.Soon the boy stopped crying,I wondered many grownups could be as kind as she was to other!
