2024年12月大学英语四级阅读模拟题仔细阅读1
Questions 46 to 50 are based on the followingpassage.
Aging happens to all of us, and is generally thoughtof as a natural part of life. It would seem silly to callsuch a thing a "disease."
On the other hand, scientists are increasingly learning that aging and biological age are twodifferent 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, theway you would treat high blood pressure or a vitamin deficiency.
Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said thatdescribing 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 thedisease and not just the side effects," he said.
"Right now, people think of aging as natural and something you can't control," he said. "Inacademic circles, people take aging research as just an interest area where they can try todevelop interventions. The medical community also takes aging for granted, and can donothing 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 theway 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 cureaging 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 thataging can be cured implies the human lifespan can be increased, which some researcherssuggest is possible. Hayflick is not among them.
"There're many people who recover from cancer, stroke, or heart disease. But they continue toage, because aging is separate from their disease," Hayflick said. "Even if those causes ofdeath were eliminated, life expectancy would still not go much beyond 92 years."
