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(活检) 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(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 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(合理的) 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.

Our risk of cancer rises as we age. So it makes sense that the elderly should be routinely screened for new tumors(肿瘤)—or doesn't it?
While such careful 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 consider the health benefits of screening and the costs of routine testing.
In many cases, screening can lead to additional 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 that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a strong reaction among doctors, patients and advocacy(拥护) 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, 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 a remaining life expectancy.
A recent study suggests that doctors start to make more right decisions about who will truly benefit from screening—especially considering the explosion of the elderly.
It's not an easy guess to make, but one that makes sense for the whole patient. Dr. Otis Brawley said, "Many doctors are ordering these tests purely to protect themselves against medical disputes(纠纷). We need to think about the good use of health care and stop talking about the rationing(定量配给制) 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.

A. adds too much to their medical bills
B. helps contribute to a long life

A. important B. reliable C. precious D. deep-rooted
3.According to Dr. Otis Brawley, why do many doctors recommend routine screening for cancer?

高二英语用适当的词完成句子中等难度题查看答案及解析
As we age, our ability to think and remember starts to deteriorate. But not everyone. Some of us have brains that age more slowly. Enter the super-ager!
Super-agers are people over the age of 80 who have the brain structures and abilities of much younger people. Eighty-seven-year-old Bill Gurolnick is a super-ager. “What do I feel like? If I was to give a number, I probably feel like I’m about my early 70s…”
Scientists know that parts of the brain decrease in size with age. But in super-agers that process is much slower. Emily Rogalski is a neuroscientist at Northwestern University’s Feinberg School of Medicine, in Chicago, Illinois. In a recent study, she showed that super-agers have young brains. The area of the brain responsible for attention and memory—the cortex—was shown to be thicker in super-agers. “When we look at the cortex of their brain, we see that, on average, that it looks more like a 50-year-old brain that it looks like an average 80-year-old bran…”
Not only do super-ages have thicker cortexes, they have more spindle neurons. These large brain cells appear to be involved with social-emotional communication. But their exact purpose is still a mystery. Scientists writing for Smithsonian magazine say they are “brain cells for socializing.”
Several factors affect how our brains age. Scientists say super-agers have several things in common, including an active lifestyle. Many travel and play sports. They are often big readers. And they usually have healthy relationships and spend time with friends. Super-agers also seem to have certain common personality traits. Rogalski says they are, for the most part, known for their optimism, resilience and perseverance. Growing old, she adds, does not have to be depressing and sad. “Perhaps, if we expected a bit better from ourselves, then we would understand that not all aging is stressful!”
Can we all be super-agers? The science behind super-aging is a relatively new, but growing field. Scientists involved in the research offer this advice as we age: Stay active. Learn new things. Challenge yourself. Surround yourself with healthy relationships.
1.What does underlined word “deteriorate” mean?
A. Become better as time passes. B. Speed up with time.
C. Improve whatever happens. D. Become worse as time passes.
2.What is the function of the cortex?
A. Be responsible for social-emotional communication.
B. Take care of attention and memory.
C. Keep track of numbers and charts.
D. Care for healthy relationships.
3.Super-agers have the tendency to ________.
A. stay at home with friends all day long
B. learn new things but seldom read books
C. be optimistic and like playing sports
D. travel a lot alone
4.The best title of the passage may be ________.
A. A New Scientific Study B. Can We All Be Super-agers?
C. How People Get Old D. Being Young Forever

The Internet has changed the world we live in dramatically, so that in some ways it is unrecognizable from the place we lived in twenty years ago. Communications have been revolutionized. Not only have cell phones found their way into most people’s pockets or purses, but they are also used for next messaging and as cameras. Long distance phone calls have been replaced by e-mail and video conferencing. Communications, person to person or company to company, have turned into a fast-paced exchange with instant response. In fact, it has become more convenient and efficient.
The other kind of communication the Internet provides is information. School children and medical researchers alike will tell you that they could not work without the Internet and its ability to connect them to any number of websites and databases of information. Many people do their banking on-line. Others plan a trip and book a flight for themselves. People do their own stock trading through the Net. Sports fans follow scores and statistics on websites. Political junkies(政治狂) gather campaign statements and debate topics, even between elections. And almost everyone who owns a computer and has Internet access has bought at least one item on-line. No wonder some young people can not imagine what life was like before the Internet.
Some Advantages of the Internet
I. ________1.________ of the Internet communication
●A fast-paced exchange replacing long distance phone calls with ________2.________ like e-mail and vedio conferencing
II. Accessibitlity to the Internet information
●On-line ________3.________ service
