Our risk of cancer rises rapidly as we age. So it makes sense that the elderly should be routinely screened(拍片检查) for new tumors (肿瘤) or doesn’t it?
While such 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 examinations and 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 (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 noisy reaction among doctors, patients and social 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 previous personal experience with the disease, should continue to get screened regularly. But for the rest, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy.
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.
It’s not an easy calculation to make, but one that makes sense for patients. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves from medical disputes（争端）. We need to think about the wise use of health care, which 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.” Routine cancer screening for the elderly people makes sense because ______.
| A．it is believed to contribute to a long life |
| B．it is part of their health care package |
| C．they are more sensitive about the health |
| D．they are in greater danger of tumor growth |
How do some researchers now look at routine cancer screening for the elderly?
| A．It adds too much to their medical bills. |
| B．They are doubtful about its necessity. |
| C．It helps increase their life expectancy. |
| D．They think it does more harm than good. |
What is the traditional view about women screening for breast cancer?
| A．It is a must for adult women. |
| B．It applies to women over 50. |
| C．It is intended for young women. |
| D．It doesn’t apply to women over 74. |
What does the writer say is the general view about health care?
| A．Better care, longer life. |
| B．Prevention is better than cure. |
| C．Better early than late. |
| D．The more, the better. |

Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago.
Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Company. The idea for the product came from an awful experience he often had while singing in his church choir. Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. Around that time, Fry heard about a new adhesive (粘合剂) that a colleague, Dr. Spence Silver, had created. This adhesive was special because it was strong enough to hold papers together, but not strong enough to tear the paper when it was removed.
A short time later, Fry realized that his new invention had even more uses than being a great bookmark. He came to this realization when he wrote a note on one of his new “bookmarks” and attached it to a report he was going to give to a colleague. Soon, co-workers were asking Fry for more of his invention so that they could use the new type of notes themselves.
Fry and some other people at 3M believed so much in the new product that they asked the company to give away thousands of the “sticky pieces of paper” for trial use. When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off.How did Dr. Spence help Art Fry?
| A．He created the Post-it Notes. |
| B．He offered the new adhesive to Art. |
| C．His adhesive made Art’s invention possible. |
| D．He often worked and discussed science with Art. |

If you could take a large snapshot (照片) of everyone in the United States today, it would contain six million more females than males. In this country, women outlive men by about seven years. Throughout the modern world, cultures are different, diets are different, ways of life and causes of death are different, but one thing is the same--- women outlive men.
It starts before birth. At conception, male fetuses(胎儿) outnumber female by about 110 to 100; at birth, the rate has already fallen to about 105 boys to every 100 girls. By the age of 30, there are only enough men left to match the number of women. Then women start taking a lead. Beyond the age of 80, there are nearly twice as many women as men.
“If you look at the top ten or twelve causes of death,” said Deborah Wingard, a disease expert at the University of California at San Diego, “every single one kills more men.” She listed out one sad fate after another – heart disease, lung cancer and so on. Each kills men at roughly twice the rate of that it does women.
More than a century ago American men surpassed and outlived the women. But in the 20th century, women began living longer, primarily because pregnancy（怀孕) and giving birth to children had become less dangerous. The gap grew steadily. In 1946, for the first time ever in the United States, females outnumbered males.
Parts of the reasons are self-made. Men smoke more, drink more and take more life-threatening chances than women. Men are murdered (usually by other men) three times as often as women are. They commit suicide at a higher rate and have more than twice as many fatal car accidents as women do. Men are likely to be involved in alcohol-related deaths.
But behavior doesn’t explain away the longevity gap.
Today, some scientists studying the gender gap believe that the data point to one conclusion: Mother Nature may be partial(偏袒) to women.
Every living thing is assembled according to instructions on its chromosomes (染色体), and humans have 23 pairs of them. But in males, one of these is a weak non-matching pair, expressed by “xy”. The agreement pair in females is “xx”, and its genetic “backup” power is sometimes listed as a clue to woman’s superior restoring force. If the male’s single “x” chromosome isn’t perfect, it is possible for a serious genetic disorder to appear. Some blood diseases, for instance, are diseases caused by a shortcoming in a single gene on the “x” chromosome. They are far more common in males than females.What may the underlined word “outlive” in Paragraph1 mean?
| A．Become stronger than. |
| B．Live longer than. |
| C．Be wiser than. |
| D．Be born more earlier than. |
What can we infer from the second paragraph?
| A．Female fetuses are more than male. |
| B．The female are surpassing the male with age increasing. |
| C．By the age of 30, the female are more than the male. |
| D．Over 90, men are more than women in the United States. |
How many exact diseases are mentioned as examples killing twice men than women?
| A．Two. | B．Three. | C．Ten. | D．Five. |
The best title for this passage is _____
| A．Why women live longer than men |
| B．Women are different from men |
| C．American men once lived longer than the women |
| D．Men smoke and drank more than women |

I remember my math teacher Mr. Young very well. He stood out because the kids made fun of him. He was missing one of his fingers, and always pointed at students with his middle finger.
I was not very good at English and math. No matter how hard I tried, I just could not figure out why I did not understand what all the other kids found so easy to learn.
One day, I was told that if I got one more E on my report card, I would be taken to the “big prison for kids”.
I tried really hard for weeks. I just couldn’t understand how to make different parts of numbers into whole things.
The day before report cards were to come out, I knew that Mr. Young would give me an E, just like he always did.
I went to Mr. Young and told him that the orphanage (孤儿院) was going to send me to the big prison if I got another E on my report card. He told me there was nothing he could do; it would be unfair to the other kids if he gave me a better grade than I had actually earned. I smiled at him and said, “Mr. Young, do you know how the kids make fun of you because you’re missing your finger?”
He looked at me, moved his mouth to one side and said nothing.
“They shouldn’t do that to you because you can’t help not having a finger, Mr Young. Just like I can’t help not being able to learn numbers and stuff like that,” I said.
The next day, when I got my report card, I tucked it into one of my books. While on the school bus, I opened it: Geography, B+; Mechanical Drawing, C-; English, D-; History, C-; Gym, B+; Art, C; Math, D-.
That math grade was the most favorite one I ever received. Because I knew that someone in the world finally understood what it was like for me to be missing a finger inside my head.From the second paragraph we can infer that the boy is ______ in some subjects.
| A．mind-blowing | B．badly-behaved |
| C．fun-loving | D．slow-witted |
Where may the boy live according to the passage?
| A．In an orphanage. | B．In a big prison. |
| C．In the school dormitory. | D．In his home. |
What grade should the boy have got in the math test this time?
| A．D | B．C | C．B | D．E |
The reason why the boy remembers Mr Young is that ______.
| A．he missed one of his fingers |
| B．he treated his students very well |
| C．he understood the boy |
| D．he taught his students in a special way |

Last December, Doris Low turned 90. Once a week she still drives to the Canadian National Institute for the Blind (CNIB) in Toronto, where she helps transform literature into Braille() to bring the power of story and knowledge to the hears and minds of blind readers. She has been volunteering her time and talents to such enterprises foe more than 40 years.
After working in the business world for a while, Low got fed up. So she turned to teaching at a technical school and later moved into the library.
Low’s mother liked reading. As her eyes began to fail, low read to her. Then “ hearing an advertisement encouraging people to learn Braille, I decided to give it a try.” In 1973, she was certified as a braille transcriber (转译者) and began transcribing books as a volunteer for the CNIB library.
The job was strenuous ---she could get to the end of a page, make a mistake on the last line, and have to do the whole thing again. For a number of years, low also worked in the CNIB sound studio reading books onto tape. Three years ago, she took up proofreading (校对) at the CNIB’s word factory.
In April, during Volunteer Week, the CNIB recognized Low for her great contributions. Thanks to volunteers like Low, the CNIB library has got more than 80,000 accessible materials for people unable to read traditional print. “ I can’t imagine how many readers of all ages have benefited from
Doris’s contribution as a skilled volunteer through her rich voice and her high degree of accuracy in the hundreds of books she has brailled and proofread over the years--- and she is still doing so,” said a CNIB official.
“For me,” said Low, “the CNIB is more than just a place to volunteer. Three thins matter most in my life: a little play, a little work, a little love. I’ve found them all here.”What does Low still do at the age of 90 at the CNIB? ( no more than 10 words)
Why did Low learn Braille? ( no more than 15 words)
what does the underlined word “strenuous” most probably mean?(1 word)
What are Low’s contributions to the CNIB? ( no more than 10 words)
