题目内容：

    It’s a Friday morning in Boston, which means Dr. Jim O’Connell is making his rounds.

He might be a little more comfortable inside an exam room, but that’s not where his patients are. Dr. Jim O’Connell is Boston’s only doctor left still making house calls to the homeless.

Nearly 600,000 Americans are homeless, and many have health problems with no access to care. O’Connell and his well-known team of “street doctors” are doing something about it, treating about 700 regular patients.

O’Connell and his team of psychologists and social workers spend their days walking around the downtown where his patients live – in parks, under bridges and on the outskirts of town. During his morning rounds, O’Connell himself usually see about 20 patients. “I feel like I’m a country doctor in the middle of the city.” he said. “You couldn’t find a more grateful population.” “This man is unbelievable!” one patient remarked. “This is my doctor. He’s been my doctor for life,” another added.

O’Connell does just about everything, from stitches (缝补)for an arm to surgery for the soul. If patients can’t be treated on the street, he finds them a temporary treatment bed in a shelter.

“Everything I had been taught to do in my medical school – go fast, be efficient – was counterproductive (适得其反) when you take care of homeless people.” O’Connell told Harvard Magazine.“When you see somebody outside, you get them a cup of coffee and sit with them. Sometimes it took six months or a year of offering a sandwich or a cup of coffee before someone would start to talk to me. But once they engage(参与), they’ll come to you any time because they trust you. I often say that the best training for this job is being a bartender because it’s all about listening.”

When asked about how his life might have turned out, had he become a highly paid doctor, O’Connell said, “I never think about it anymore.”
