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.

C. The elderly are more sensitive about their health.

D. The elderly are in greater danger of tumor(肿瘤) 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. 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.

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.

1. Some researchers now think that routine cancer screening for the elderly 　　　　　　　 .

A. adds too much to their medical bills

B. helps contribute to a long life

C. can prevent tumor growth

D. is not always necessary

2.The underlined word "ingrained" in Paragraph 3 most probably means "　　　　　　 ".

A. important B. reliable C. precious D. deep-rooted

3.According to Dr. Otis Brawley, why do many doctors recommend routine screening for cancer?

A. Because they want to get more money from the health care system.

B. Because they want to perform their normal duties actively.

C. Because they want to avoid possible trouble.

D. Because they want their patients to suffer less.

4. What does the author mainly argue for?

Regularly staying late at the office significantly increases the risk of having a stroke or heart attack, researchers have found, working just an hour extra each day pushes up stroke risk by 10 per cent, according to a huge review of working patterns. And people who work an extra three hours a day--or 55 hours a week--are 33 per cent more likely to have a stroke, the scientists found.

The research, published in the Lancet medical journal, is based on health records of more than 500, 000 people across Europe, the US and Australia.

Scientists led by University College London warned that people who work longer hours tend to do less exercise, sit at a computer for hours at a time and drink more than people with a better work-life balance. Repeated stress may also be to blame for greater health problems, the scientists think.

They looked at the combined result of 17 previous studies, in which 529, 000 people were tracked over an average of seven years.

Experts stressed that the study had only found a link between hours worked and heart problems---it had not proved what had actually caused each death. But they warned people to take note of the findings.

Dr Tim Chico, consultant cardiologist at Sheffield Teaching Hospitals, said “For many people, reducing their working hours would be difficult or impossible, and this study does not show that it would reduce the risk of stroke." Most of us could reduce the amount of time we spend sitting down, increase our physical activity and improve our diet while working and this might be more important the more time we spend at work.

1.Which areas are involved in the research?

A. The US, Australia and Russia.　　

B. Japan, Britain and China.

C. China, Russia and Japan.

D. Europe, the US and Australia.

2.Which factor is NOT the cause of the higher risk of health problems?

A. Excessive drinking.　　　　　　　 B. A healthy diet.

C. Repeated stress.　　　　　　　　　 D. Lack of exercise

3.What can we infer from the passage?

A. People who work longer are less likely to suffer a stroke.

B. All the deaths are caused by working long hours.

C. The research was based on the tracking of over 500, 000 people.

D. Reduced working hours will surely decrease the risk of stroke.

4.Where is this passage probably taken from?

A. A news report.

B. A science magazine.

C. A psychological journal.　

D. A hospital introduction.

Two new studies suggest that modern running shoes could increase the risk of injuries to runners．

One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week．The runners were observed on a treadmill machine（跑步机）．Sometimes they wore running shoes．Other times they ran barefoot．

Researchers found that running shoes create more stress that could damage knees，hips and ankle joints than running barefoot．They observed that the effect was even greater than the effect reported earlier for walking in high heels．

The other study compared runners in the United States and Kenya．The researchers divided the runners into three groups．One group had always run shoeless．Another group had always run with shoes．And the third group had changed to shoeless running．

Runners who wear shoes usually come down heel first．That puts great force on the back of the foot．But the study found that barefoot runners generally land on the front or middle of their foot．That way they ease into their landing and avoid striking their heels．

Daniel Lieberman says the way most running shoes are designed may explain why those who wear them land on their heels．The heel of the shoe is bigger and heavier than other parts of the shoe，so it would seem more likely to come down first．Also，the heel generally has thick material under it to soften landings．

But the researchers do not suggest that runners immediately start running barefoot．They say it takes some training．And there can be risks，like running when your feet are too cold to feel if you get injured．

1.What’s the main idea of the passage?

A. Running in shoes is partly good to runners.

B. Two new discoveries encourage people to run in high heels.

C. Walking in high heels could cause less serious effects than running barefoot.

D. Two new studies prove running without shoes is beneficial to runners in most cases.

2. From the fifth paragraph we can infer that__________.

A. running barefoot is faster than running in shoes.

B. the landing point is very important in running.

C. running shoeless can give people a real exercise.

D. different running ways cause different injuries.

3.Why do people who run in shoes land on their heels?

A. Because the shoes put great force on the back of the foot.

B. Because the design of running shoes is unreasonable.

C. Because people who often run get used to landing on their heels.

D. Because the running people want to run faster.

4.What’s the writer’s attitude towards the use of the modern running shoes?

A. Positive.　　　　 B. Persuasive.

C. Objective.　　　 D. Supportive.
