问题     The physicians in a hospital form the core of the medical staff. But they couldn’t provide effective medical care to their patients without the help of numerous other medical employees. From the viewpoint of the patients, the nursing staff is particularly important. Nurses are usually in close contact with patients as long as they are in the hospital.
    A nurse does not study for as many years as a doctor. However, each must be equally dedicated. Caring for sick persons requires a great deal of patience and concern. Most nurses work long days, and they often must work at odd hours or during the night.
    Under the supervision of the head nurse, the nursing staff must provide nursing services on a 24-hour basis and attend to patients’ needs. This responsibility continues around the clock, and so nurses must work in shifts. A shift is a period of duty, usually eight in length. The nurses on the ward rotate their shifts. All of them work out of a central area on the ward called the nurses’ station.
    A nurse must always be alert. She can never afford to be careless. This is true in all nursing situation, but it is especially true in the intensive care unit. Patients under intensive care are critically ill, and they must be monitored at all times. The nurses who do intensive care duty have one of the most demanding jobs in the hospital.
    Serving as a nurse can be a very rewarding job. But it is not an easy one. Not every person is suited to become a nurse. Only very dedicated people have chosen nursing as a profession.
Why must nurses work in shifts?

选项 A、Because they are careless.
B、Because nursing services must be provided continuously.
C、Because they work at night from time to time.
D、Because a shift is usually eight hours long.

答案B

解析 本题是一道具体细节题。问为什么护士必须轮班工作。利用查阅式阅读法,我们可以发现文章第三段指出,在护士长的监督下,医护人员必须一天24小时不问断地提供护理服务和照管病人的需要。这种任务要求24小时连续工作,因此护士们必须轮班工作。所以,本题的正确答案应是B“因为护士的护理工作不能间断”。
