I have a dream since I was young. I want to be a doctor to help patients. When I was young, I was very weak and often fell sick. I went to hospital to see a doctor. He was very helpful and kind. I think that is why I want to be a good doctor in the future. To be a doctor when I grow up, I have to study hard and help my classmates with their homework now.
