A) A good doctor should be well-educated because he has to diagnose different illnesses. He should be patient because he works with different people. He should be professional because he has a very responsible job. He should be friendly because patients don't like very serious doctors. He ought to be hard-working because sometimes he has to stay long hours in hospital. A good doctor must be very dedicated to his work.
b) A good nurse should also be professional because she does different things to people who are at hospital. She gives injections so she has to be really careful when she doesn't want to hurt anybody. She should be patient because people in hospital are often in pain and complain about everything. She should be understanding and helpful. A good nurse must be well-educated and intelligent. It is also good when a nurse has a great sense of humour.
