My Friend’s Job

  One of my friends is a doctor. He receives many patients every day. Every patient is different, so he must ask carefully about the the patients' situation , such as which pain, how pain  so on. Make sure the situation is accurate, he might give the patients some physical examination, for example X-ray, blood text  so on. Depending on the result of the examination, he would make an advice for  the treatment. After the patients' agreement, he would give some medication. If the patient's situation is quite serious, he might make the operation for the patient.
