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."

Actually we have known a lot of examples and meaningful words to support the fact that we should try our best to ease the bad impression of others. Just like the old saying goes, we should give a better assumption to the one than we think he was. But many of us always fail to do this.

Take the situation of my class for example. Right at the beginning of the first semester when we were freshmen we all showed great favor to each other. And when there was an activity that needed some people to join, we would be willing to attend whether it was interesting or not. And we were really like brothers and sisters, and our class was just like a family, a warm family. But now, I feel tired of those meaningless activities not only because of the boring activities themselves but also the cool response of our classmates.

I think the reasons why the passion of most classmates is so low may be as follows:

To start with, many of us take part in more than one organization, which will certainly make us tired. Also, in the study fields, many of us may find that our courses are sometimes difficult to understand or comprehend, especially the specialized subjects. Moreover,　 "history" teaches us that if one does not study hard, it is possible to fail in the exams. So it is a big and good excuse to say that "I do really want to attend, but I have a lot of horse work to do, so'"."

Last but not least, some people believe that some of our leaders should not be regarded as a leader, maybe I should say we, as leaders, lost the reputation, support and trust of yours. At least I am the warm-hearted one, although I cannot promise you that your advice will be adopted surely, at least I will spare no effort to "give" you the right to be heard, and to serve you.

Be active to show your talents and abilities and to create a better image of our class. Most important of all, work painstakingly for a better condition that we should have reached.

1.At the beginning of the first semester the students were_____ each other.

A. quite curious about　　　 B. active and kind to

C. full of sympathy to　　　 D. specially tired of

2.Now the students are unwilling to get involved in the activities because they are______.

A. not easy to organize　　　 B. costing too much time

C. difficult to comprehend　 D. meaningless and boring

3.Which of the following statements is TRUE?

A. Students' passion for activities was high at first but disappeared gradually.

B. Students' passion for activities grew gradually because they were interesting.

C. Students were too busy to take part in activities after their classes.

D. Students were unwilling to participate in activities because of their leaders.

4.We can infer from the passage that the writer must be　　　　　　 .

A. a supporter of activities

B. a responsible teacher

C. a top student in class

D. a devoted class leader

If you make a list of the world's top ten most challenging jobs,chances are that being a teacher will not make the cut.But think about the discouraging task millions of educators face each day as they try to shape a group of often bad-tempered,wild kids into intelligent,well-rounder individuals.That surely has to be the toughest job in the world, especially given that there is no promotion or bonus awaiting them even if they are wildly successful!

What if there all-important individuals that we often take for granted（想当然）disappear from our lives?That was what Project Ed and Participant Media's Teach campaign asked filmmakers of all ages to imagine in their recently-held competition.Entitled "A World Without Teachers",its purpose was to inspire more young people to become teachers.However,the 62 amazing video submissions also serve as a reminder of how horrible things would be if we didn't have these selfless individuals guiding us through life.What was interesting is that even the youngest participants did not appear to be happy at the idea of not having anybody telling them what to do.

High-school student Savannah Wakefield reflected if art as we know it today would have been different without teachers.Would Monet have discovered his talent for impressionism?Los Angeles-based Miles Horst,who won the 1000 USD prize for the best adult submission imagines a world where teachers are replaced by a “brain box” in his fun lively entry.

Youth category winner Marina Barham's video represents a fact we all know but often forget.Teachers don't just teach,they inspire something that no electronic device,no matter how smart,can do!So the next time you think your teacher is being "mean" for trying to channel you in the right direction,imagine a life without him/her.We have a feeling it will not appear as rosy!

1.What is the text mainly about?

A. The significance cf teachers.

B. The campaign to promote teachers' status.

C. A survey of people's views about teachers.

3.What is the purpose of the project “A World Without Teachers”?

4.What does the underlined sentence in Paragraph 4 suggest?

You may not be aware, but digital currency (货币) is a big part of the Internet world. QQ Coins can buy you accessories (配饰) for your QQ images. More importantly, a new digital currency, Bitcoin, is bringing the world’s commerce online.

If you’re traveling, you can spend Bitcoins at restaurants and hotels listed at BitcoinTravel.com. In China, Bitcoins can be used to buy goods at about 134 online shops on Taobao. And at a café named 2nd Place in Beijing, you can even buy fresh coffee with Bitcoins.

So what makes Bitcoin so attractive to investors?

First of all, the Bitcoin system is not controlled by anyone. One central authority cannot make policies to change the value of Bitcoins. The fixed amount of Bitcoins also means they cannot lose value through inflation(通货膨胀), as all forms of paper money have done over time.

In addition, accounts in the Bitcoin system are anonymous and transparent. Users can set up an account easily and track every Bitcoin. All of these features seem to make Bitcoins immune(有免疫力的) from loss, but that is not entirely true.

“The value of Bitcoins can vary wildly as no central government makes the price of them steady. If the value drops suddenly, investors cannot get any compensation(赔偿),” Zhao Qingming, a senior researcher at China Construction Bank, told China Economic Weekly. And Bitcoins, unlike company shares, are not backed by any tangible funds, which also adds to their risk.

While China will not recognize the digital currency anytime soon, Xinhua said, lawmakers and officials at a hearing on Nov. 18 in the US made positive comments about Bitcoin.

Ben Bernanke, outgoing chairman of the Federal Reserve, told the Washington Post that “these types of creations, such as Bitcoin… may hold long-term promise, particularly if its system promote a faster, more secure and more efficient payment system.”

1.Bitcoin is ______.

A. actually exactly like QQ Coins

B. only used online

C. a new currency used both online and in real life

D a country’s new digital currency.

2.We can use Bitcoin to buy the following things except ______.

A. online goods

B. goods at 134 online shops on Taobao

C. books in physical shops

D. coffee at a café named 2nd Place

3.What is the disadvantage of Bitcoin?

A. the value of it can rise and fall wildly.

B. It cannot lose value through inflation.

C. Every bitcoin in your account can be followed.

D. It can even be used at some specific restaurants and hotels.
