Our risk of cancer rises rapidly as we age. So it makes sense that the elderly should be routinely screened(拍片检查) for new tumors (肿瘤) or doesn’t it?
While such 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 additional examinations and operations to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not cause serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained (根深蒂固的) that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a noisy reaction among doctors, patients and social 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 previous personal experience with the disease, should continue to get screened regularly. But for the rest, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy.
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.
It’s not an easy calculation to make, but one that makes sense for patients. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves from medical disputes（争端）. We need to think about the wise use of health care, which 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.”
1. Routine cancer screening for the elderly people makes sense because ______.
A. it is believed to contribute to a long life
B. it is part of their health care package
C. they are more sensitive about the health
D. they are in greater danger of tumor growth
2.How do some researchers now look at routine cancer screening for the elderly?
A. It adds too much to their medical bills.
B. They are doubtful about its necessity.
C. It helps increase their life expectancy.
D. They think it does more harm than good.
3. What is the traditional view about women screening for breast cancer?
A. It is a must for adult women.
B. It applies to women over 50.
C. It is intended for young women.
D. It doesn’t apply to women over 74.
4.What does the writer say is the general view about health care?
A. Better care, longer life.
B. Prevention is better than cure.
C. Better early than late.
D. The more, the better.

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 additional biopsies and surgeries to remove cancer, which can cause side effects, 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 ingrained that when health care experts recommended 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 make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing 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.
1.Why do doctors recommend routine cancer screening for elderly people?
A. It is believed to contribute to long life.
B. It is part of their health care package.
C. The elderly are more sensitive about their health.

2.How do some researchers now look at routine cancer screening for the elderly?
A. It adds too much to their medical bills.
B. It helps increase their life expectancy.
C. They are doubtful about necessity.
D. They think it does more than good.
3.What is the conventional view about women screening for breast cancer?
A. It applies to women over 50.
B. It is a must for adult women.
C. It is optional for young women.
D. It doesn’t apply to women over 74.
4.Why do many doctors prescribe routine screening for cancer?
A. They want to protect themselves against medical disputes.
B. They want to take advantage of the medical care system.
C. They want data for medical research.
D. They want their patients to suffer less.
5.What does the author say is the general view about health care?

One of the things that makes your smart-phone so smart is that if you pull it out in the sun, it senses that—and dials up the screen brightness to compensate. But it’s not a perfect solution.
“First of all, it’s still not bright enough—you have to remember how respectable sunlight is.” Shin-Tson Wu, a physicist at the University of Central Florida. The other problem, he says of the brightened screen, is it kills the battery. So Wu and colleagues have produced a battery-sparing alternative: an anti-reflective screen-coating. Based on the eyes of moths. “Nature is so rich! We can learn a lot from nature. “The thing Wu and others have learned about moth eyes, is that they’re uneven, dotted with tiny projections. That uneven surface reduces the reflection of light off their eyes- thought to help the bugs escape predators (捕食者), and see better in low light. So Wu and his team built a similar surface with tiny dimples (凹), to cut down on glare. He says the dimpled coating could improve the readability of a screen by five to 10 times, compared to a normal smart-phone screen. The details are in the journal Optica.
The tech hasn’t been commercialized yet, and that could take a few years. Which gives researchers time to take advantage of another property of these surfaces: they’re flexible. Meaning the possibility of bendable displays. Combine that with the bendy batteries we reported on in a recent podcast(播客), and it looks the smart-phones of the future could be set for a real transformation.
1.Why do the researchers develop the anti-reflective screen-coating?
A.To brighten the screen. B.To make profits.
C.To take in the sunlight. D.To save the use of battery.
2.What inspired the invention of the screen?
A.The predators. B.The reflection of light.
C.The eyes of moths. D.The smooth surface.
3.How does the screen work?
A.It helps bugs escape.
B.It slows down reading.
C.The smooth surface protects our eyes.
D.The rough surface decreases the reflection of light.
4.What do the researchers expect of the screen?
A.I’ll transform itself. B.I’ll be environment-friendly.
C.I’ll reach consumers soon. D.I’ll be powered by recyclable batteries.
