问题     Aging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call such a thing a "disease."
    On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.
    Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments.
    "It unties the hands of the pharmaceutical (制药的) industry so that they can begin treating the disease and not just the side effects," he said.
    "Right now, people think of aging as natural and something you can’t control," he said. "In academic circles, people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range."
    "But if aging were recognized as a disease," he said. "It would attract funding and change the way we do health care. What matters is understanding that aging is curable."
    "It was always known that the body accumulates damage," he added. "The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions."
    Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them.
    "There’re many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease," Hayflick said. "Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years."
What does Professor Leonard Hayflick believe?
选项 A、The human lifespan cannot be prolonged.
B、Aging is hardly separable from disease.
C、Few people can live up to the age of 92.
D、Heart disease is the major cause of aging.
答案A
解析 本题可参照文章的倒数第2段。从文章的倒数第2段可知，旧金山加利福尼亚大学教授Leonard Hayflick说，衰老可以治愈的想法意味着人类的寿命可以延长，一些研究者认为这点是有可能的。Hayflick对这种观点并不赞同。A项正确。B、D两项不正确，文中说很多人从癌症、中风或心脏病中康复。但他们继续衰老，因为衰老与他们的疾病是不相关的。C项不正确，文中说即使这些死亡原因被消除了，预期寿命仍然不会超过92岁。A项与文章的意思相符，因此A项为正确答案。
