Apart from my mother, I've been very lucky to having had two teachers who have been fundamental influences in my life. The first was my first piano teacher. She really got me interesting in the piano and made a huge impression in me at a very early age. She helped me to learn the basic techniques and develop understanding of the instrument. Then, when I was 16, I start studying with my second inspirational teachers. He made me much more confident and encouraged me to enter for competitions even when I felt certain and unconfident about doing this. He had enormous faith in us, and it was this, more than anything else, which inspired me to make music my career.

【題目】根據(jù)短文理解，選擇正確答案。
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(警覺的) 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(活檢) 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(預(yù)期壽命).
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(腫瘤) 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.
