Every one has his dream. Some want to be teachers,others want to be scientists. My dream is to become a doctor. My friends asked me why. I told them my story. When I was a small boy I was very weak. Once I was terribly iii. I had a high fever. My parents sent me to the hospital but the doctors could do nothing for me. Then my parents heard there was a very good doctor in another town. They took me there. I was saved. A good doctor can save people' s lives. From then on I decided to become a doctor. I know it is not easy to be a doctor.But I am determined to study hard. I am sure my dream will come true.
