 There are many interesting and noble (1) professions. I want to be a doctor. It is an interesting profession.
   I understand that it is necessary (2) to study a lot to become a doctor. I also understand that this profession requires (3) great responsibility (4) because it deals with the most precious thing one has — with his health.
   My grandfather is a doctor and he works as a surgeon (6) in hospital. I have been several times at the hospital and spent some time watching him working.
   His main task is to operate on people. After each operation he takes care of the patients until they recover (7). He examines people and gives them professional advice.

   I know that he wants to see all his patients able-bodie notice that he is happy when his patients recover.
