问题     Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors—or doesn’t it?
    While such vigilant (警觉的) tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it’s important to weigh the health benefits of screening against the risks and costs of routine testing.
    In many cases, screening can lead to surgeries to remove cancer, while the cancers themselves may be slow-growing and may not pose serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so deep-rooted that when health care experts recom-mended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups.
    It’s hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy (预期寿命).
    A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening—especially considering the explosion of the elderly that will soon swell our population.
    It’s not an easy calculation to make, but one that makes sense for all the patients. Dr. Otis Brawley said, ’Many doctors are ordering screening tests purely to cover themselves. We need to think about the rational use of health care."
    That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.
What does the author say is the general view about health care?
选项 A、The more, the better.
B、Prevention is better than cure.
C、Better early than late.
D、Better care, longer life.
答案A
解析 本题询问关于医疗保健的普遍看法。题干中的view一词对应最后一段后半部分的belief。该段提到“当涉及到医疗保健时，越多总是越好”，这属于被误导的观念，也即是普遍的看法，A“越多越好”的表述跟原文more is always better一致，故为答案。B“预防比治疗要好”，C“早比晚好”和D“保健得越好，寿命就越长”均是利用常识干扰，但题千限定是作者笔下(What does the author say)人们关于医疗保健的普遍看法。原文最后一段段末的when it comes to health care，more is always better，清楚表明此为答题依据，A的表述与此一致。
