To bee a doctor in the United States, students usually attend four years of medical school after they plete college. Then these young doctors work in hospitals for several years to plete a training program called a residency(住院医生实习期).
These medical residents provide hospitals with needed services in return for not much pay. They work under the supervision(管理) of medical professors and more experienced doctors. Medical residents treat patients . they carry out tests. They perform operations. They plete records. In hospitals with few nurses, residents also do work formerly done by nurses. Some medical residents work one-hundred or more hours in a single week. They often work for more than thirty-six hours at a time before they can rest.
Critics (批评家) of this system say medical residents work too long and do not get enough res. They say these young doctors may be too tired to perform their medical duties effectively. Now, the government will limit the number of hours of work that residents can work. Most doctors in training will be limited to eighty-four hours of work each week. They will have work periods of no more than twenty-four hours at one time. They will have ten hours of rest between work periods.
Medical residents will have one day each week when they do not have to work. Any work they accept outside their hospitals will be limited．Experienced doctors and medical professors will closely supervise the residents to make sure they are not too tired to work.
Many medical residents weled the work limits. Others, however, said the new policy may interfere with patient care and their own medical education.
