When it comes to medical care, many patients and doctors believe "more is better." But what they do not realize is that overtreatment-too many scans, too many blood tests, too many procedures-may bring harm. Sometimes a test leads you down a path to more and more testing, some of which may be attacking, or to treatment for things that should be left out.

Terrence Power, for example, complained that after his wife learned she had Wegener's disease, an uncommon disorder of the immune system(免疫系统), they found it difficult to refuse testing recommended by her doctor. The doctor insisted on office visits every three weeks, even when she was feeling well. He frequently ordered blood tests and X-rays, and repeatedly referred her to experts for even minor complaints. Even when tests came back negative, more were ordered, and she was hospitalized as prevention when she caught a cold. She had as many as 25 doctor visits during one six-month period. The couple was spending about $30,000 a year for her care.

After several years of physical suffering and near financial ruin from the medical costs, the couple began questioning the treatment after discussing with other patients in online support groups. "It's a really hard thing to determine when doctors have crossed the line," Mr. Power said. "You think she's getting the best care in the world, but after a while you start to wonder: What is the purpose?" Mr. Power then spoke with his own primary care doctor, who advised him to find a new expert to oversee Mrs. Power's care. Under the new doctor's care, the regular testing stopped and Mrs. Power's condition was stable. Now she sees the doctor only four or five times a year.

1.Which of the following was a problem for Mrs. Power during her medical treatment?

A.She had to be hospitalized for three weeks whenever she had a cold.

B.Her doctor asked her to consult other experts for her complaints.

C.When test results showed she was fine, her doctor still ordered more tests.

D.She did not have any insurance, so she became penniless.

2.When did the Powers start to doubt the treatment of Mrs. Power?

A.After they knew about the treatment of other patients.

B.After they analyzed the results of her blood tests

C.After Mrs power was cured of her illness.

D.After the new expert tested her.

3.Which of the following can replace the underlined word "stable" in the last paragraph?

A.not getting worse B.improper

C.unchangeable D.uncertain

4.What is the main idea of this passage?

A.Treatments do not always cause harmful side effects.

B.Patients tend to believe more testing is better treatment.

C.Doctors generally recommend office visits that are necessary.

D.Too much medical care may not be beneficial to patients.

高二英语单项填空简单题查看答案及解析

BEING an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating in zero gravity(重力).

However, there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show – because it's impossible to cry in zero gravity.

Of course, astronauts can still produce tears. But crying is much more difficult in space, reported The Atlantic in January. Without gravity, tears don't Flow downward out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go—they just stick to your eyes.

In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off of your eye... They just kind of stay there."

Besides making your Vision unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that's not the case in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is painful like crazy." Feustel told his teammate during the walk.

Since gravity doesn't work in space, astronauts need some extra help to get rid of the tears. Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait—"When the tears get big enough they simply break free of the eye and float around," astronaut Ron Parise told The Atlantic.

There are lots of small things—things like crying – that we are so used to on Earth. We usually take them for granted, until they become a problem in a totally different environment, like space. There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp (打嗝), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up (呕吐) everything in their stomach, according to the UK National Space Center.

Thus, perhaps it's only space explorers who can honestly say: "Gravity, you're the best."

1.What can we conclude from paragraphs 2 and 3?

A. Astronauts are unable to feel sad in space.

B. Astronauts produce fewer tears in space.

C. Tears produced in space flow down more slowly.

D. Tears produced in space don't flow downward.

2.What effect do tears have on astronauts?

A. They cause physical pain.

B. They bring comfort to them.

C. They make their vision clearer

D. They float around and cause trouble.

3.What can the astronaut do to get rid of the tears?

A. Rub his eyes against his helmet to let the tears float forward.

B. Rub his eyes by hand to let the tears float around.

C. Get the tears big enough to fall off of his eyes.

D. Get the tears big enough to break away from his eyes.

4.When of the following can be the best title for the text?

A. In the sky, you can't burp

B. Better life with gravity

C. In the sky, you can't cry

D. No Gravity, no tears

Aging happens to all of us, and is generally thought as a natural part of life. It would seem silly to call such a thing a　 “disease”.

On the other hand, scientists are increasingly learning that aging and biological age are two different 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, the way you would treat high blood pressure or a vitamin deficiency.

Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates encouragement to develop treatments.

“It unties the hands of the pharmaceutical(制药的) industry so that they can begin treating the disease and not just the side effects,” he said.

“Right now, people think of aging as natural and something you can't control.” he said. “In academic circles, people take aging research as just an interest area where they can try to develop interferences. The medical community also takes aging for granted, and can do nothing 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 the way 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 cure aging 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 that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them.

“There're many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease,” Hayflick said. “Even if those causes of death were removed, life expectancy would still not go much beyond 92 years.”

1.What do people generally believe about aging?

A.It should cause no alarm whatever the circumstances.

B.It should be regarded as a kind of disease.

C.They just cannot do anything about it.

D.They can delay it with advances in science.

2.How do many scientists view aging now?

A.It might be prevented and treated.

B.It can be as risky as heart disease.

C.It results from a vitamin deficiency.

D.It is an irreversible(不可逆转的) biological process.

3.What do we learn about the medical community?

A.They now have a strong interest in research on aging.

B.They differ from the academic circles in their view on aging.

C.They have ways to prevent people's aging process.

D.They can contribute to people's health only to a limited extent.

4.What does Professor Leonard Hayflick believe?

A.Aging is hardly separate from disease.

B.The human lifespan cannot be lengthened.

C.Few people live up to the age of 92.

D.Heart disease is the major cause of aging.
