The predictability of our death rates is something that has long puzzled social scientists. After all, there is no natural reason why 2,500 people should accidentally shoot themselves each year or why 7,000 should drown or 55,000 die in their cars. No one establishes a quota (定额) for each type of death. It just happens that they follow a consistent pattern year after year.
A few years ago a Canadian psychologist named Gerald Wilde became interested in this phenomenon. He noticed that mortality rates for violent and accidental deaths throughout the Western world have remained strangely static throughout the whole of the century, despite all the technological advances and increases in safety standards that have happened in that time. Wilde developed an interesting theory called “risk homeostasis”. According to this theory, people naturally live with a certain level of risk. When something is made safer, people will get around the measure in some way to get back to the original level of danger. If, for instance, they are required to wear seat belts, they will feel safer and thus will drive a little faster and a little more recklessly, thereby statistically canceling out the benefits that the seat belt offers. Other studies have shown that where a crossing is made safer, the accident rate invariably falls there but rises elsewhere along the same stretch of road as if making up for the drop. It appears, then, that we have an inborn need for danger. In all events, it is becoming clearer and clearer to scientists that the factors influencing our lifespan are far more subtle and complex than had been previously thought. It now appears that if you wish to live a long life, it isn’t simply a matter of paying attention to certain precautions such as eating the right foods, not smoking, and driving with care. You must also have the right attitude. Scientists at the Duke University Medical Center made a 15-year study of 500 persons personalities and found, somewhat to their surprise, that people with a suspicious or mistrustful nature die prematurely far more often than people with a sunny disposition. Looking on the bright side, it seems, can add years to your life span.

Like many languages spoken by people, Ayapaneco is dying. Only two people in the world still speak it, and they won't talk to each other.
Spoken in Mexico for centuries, Ayapaneco is one of 68 surviving languages in the mainly Spanish-speaking nation. The two speakers are Manuel Segovia and Isidro Velazquez. Though they live only 500 meters from each other in the village, the two men seldom talk to each other. Daniel, an American expert, who is working to make a dictionary of Ayapaneco, says the two men “don’t have a lot in common,” and that Segovia can be “active” while Velasquez tends to mind his own business and stay at home.
While Segovia still speaks to his wife and son in Ayapaneco, neither of them can manage more than a few words. Velasquez hardly speaks his native tongue any more. Daniel is working to preserve the language in dictionary form before its last surviving speakers pass away. According to Daniel, Ayapaneco and the other languages began dying out with the introduction of public Spanish education in the mid-20th century. For decades, local children weren’t allowed to speak anything else. Many people to cities, starting in the 1970s, also helped the dying out of native languages.
Ayapaneco is the name given to the language; Segovia and Velazquez call it “Nuumte Oote”, which means “true voice”. Neither man, however, speaks the same language. The dictionary will contain two versions(版本) of the language when it comes out later this year. Those behind the dictionary aren’t the only ones trying to save Ayapaneco. The National Language Institute plans to hold classes so that Segovia and Velasquez can pass on what they know to children.
It is thought that there are about 6,000 languages spoken on earth and that about half will disappear over the next 100 years. Let’s hope the “true voice” isn’t one of them.
Segovia and Velasquez seldom talk to each other in Ayapaneco because they___________________.

A.both dislike the language
B.don’t get along well with each other
C.are too busy to talk to each other
D.don’t share the same interests

Which are the main reasons why the language Ayapaneco started dying out?

One day, a poor boy who was trying to pay his way through school by selling goods from door to door found that he had only one dime left. He was hungry so he decided to beg for a meal at the next house.
However, he became nervous when a lovely young woman opened the door. Instead of a meal, he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?”
“You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” He said, “Then I thank you from the bottom of my heart.” As Haward Kelly left that house, he not only felt stronger physically, but it also increased his faith in God and the human race. He was about to give up and quit before this point.
Years later, the young woman became seriously ill. The local doctors were baffled. They finally sent her to the big city, where specialists could be called in to study her rare disease. Dr. Haward Kelly, now famous was called in for the consultation. When he heard the name of the town she came from, a strange light filled his eyes. Immediately, he rose and went down through the hospital hall into her room.
Dressed in his doctor’s gown he went in to see her. He recognized her at once. He went back to the consultation room and determined to do his best to save her life. From that day, he gave special attention to her case.
After a long struggle, the battle was won. Dr. Kelly requested the business office to pass the bill to him for approval. He looked at it and then wrote something on the side. The bill was sent to her room. She was afraid to open it because she was positive that it would take the rest of her life to pay it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words,
“Paid in full with one glass of milk.”
(Signed) Dr. Haward Kelly
Tears of joy flooded her eyes as she prayed silently, “Thank You, God. Your love has spread through human hearts and hands.”

When I was growing up in the suburbs of New York, our first local Earth Day was organized around a drive to a town field where families were urged to empty items from their basements (地下室)for recycling rather than dropping them in the dustbin. It was an eye opening idea for a kid in 1970.
But as an environmental reporter, I'm bored of the large amount of deals and promotions that arrive by email or in my office or home mailbox on Earth Day. Like Valentine's Day, Earth Day has become a huge marketing opportunity—a way to promote consumption.
In fact, Earth Day is such a good sales opportunity that some shops, like Target, have expanded Earth Day into Earth Month.
There isn't time to give you a variety of the Earth Day shopping opportunities I was informed of this past week. They included deals on buying bottled water and earth-friendly wipes.
My award for the silliest promotion: a plan to gift 25 of the most environmentally conscious stars with unique, useful and “green” products and services, including skin care products, cheese-cake and artwork. My guess is most of the stuff will end up in celebrities' garbage.
Is buying and selling a good way to celebrate and protect the environment? I would argue that Earth Day might be an occasion to consider giving up purchases or habits that are environmentally questionable or that we could happily do without. How about not buying bottled water, but refilling a water bottle? How about not buying foods—even “organic” foods—that are packed in non-recyclable plastic?
Don't get me wrong. The company of Bridgestone is celebrating Earth Day by promising to repurpose a spent tire(利用废旧轮胎)for every tire that it sells. Verizon will plant a tree for each cell phone you trade in. Some coffee stores will even refill reusable cups at no charge. Target is giving out free reusable carrier bags without requiring a purchase.
But few shopkeepers are taking the next step-charging a fee at the cash register for disposable plastic bags, a common practice in Europe-to encourage customers to use those new reusable carriers.
Earth Day is transient(短暂的). If you only showed love on Valentine's Day, would that really mean anything at all?
The author's first local Earth Day was celebrated by ___________.

A.driving to the town field
B.emptying waste for recycling
C.looking for good ideas for reuse
D.clearing items from their basements

Why do some people expand Earth Day into Earth Month?

A.Because many activities are organized for the day.
B.Because they intend to make many sales strategies.
C.Because they want to have more selling opportunities.
D.Because they have to deal with too much waste.

According to the author, it's environmentally friendly to .

A.buy packed organic foods
B.offer stars green products
C.refill water bottles
D.ask for free plastic bags

It could be inferred from the text that Bridgestone and Verizon .

A.are likely to misunderstand the author
B.have a good way to celebrate Earth Day
C.are devoted to making money on Earth Day
D.make wrong promotion plans on Earth Day

“If you have not played video games, your childhood should be called 'incomplete'.” That's from Zhan Zaozao, 29, the screenwriter(编剧)of Play to Grow Up, a 40-minute short movie.
It tells the story of two men growing up fans of video games and how they find happiness in games. While people think playing games makes one lazy and is a waste of time, Zhan tries to prove that one can make a living out of it. In the movie, the two heroes, Dunzi and Yanjing, who are in middle school, visit a video games room on the street each day after school.
But why make a short movie about video games, since there are lots to write about childhood, such as puppy love, sports and study? “Playing games is so important to everyone's childhood from little kids to teenagers, though it's a bittersweet experience,” said Zhan. According to him, his teachers and parents didn't allow video games, but they played games “under their noses ” anyway.
In the movie, the two playmates follow different paths after school. Dunzi opens a small store selling gaming products. Yanjing works as a manager in his father's company, After years of working and facing various problems in life, they get together again, build a video game machine and play on the street. Free, simple and happy. They rediscover the carefree childhood, which they have lost in the adult world.
Many consider playing games as a bad influence, but it isn't all true, according to Zhan. “It can change your attitude toward life,” said Zhan. “On the other hand, the movie also tells you that, although the world of video games is fun, you must face real life at the end of the day. ”
What is the purpose of Zhan writing the short movie?

A.To memorize his past.
B.To offer an exciting movie.

Dennis Sinar, 51, a doctor from Washington, N. C., is quick to explain why he took a yearlong break from his job. “I was pretty burned out after practicing medicine for 26 years. I needed a recharge.” So he took a “gap year”, from July 2011 to June 2012, to explore things like ancient buildings, antique restoration, and traditional Eastern medicine, in locations including Alaska, Nepal and Romania.
“Taking a break from work is an excellent way for adults to go into a new career or refresh an old one,” said Holly Bull, president of the Center for Interim(过渡时期)Programs in Princeton, N, J., which sets up gap-year programs. The group works mainly with college-age students, but it has also served older adults since it was formed 28 years ago. “In recent years, mid-career breaks have been gaining more interest,” she said. A report on adult gap years published this year by a market research company also described the potential(潜在的)American market for gap years as a “sleeping giant.”
“A gap year is a challenge for the older individual to step out of a comfort zone and take a risk. I enjoyed that side most.” said Dr. Sinar, who kept a daily blog about his experience. His time studying Eastern medicine “reaffirmed(再次肯定)the reasons I went into health care,” said Dr. Sinar, who returned to practice medicine at his old job, although he works fewer days. “I use those experiences to provide my patients with more care,” he added. “And I listen better than I did before.”
George Garritan, chairman of the Department of Leadership and Human Capital Management at New York University, certainly agrees with Dr. Sinar. He said a gap-year experience could be worthwhile for employees and companies. For employees, investing in themselves and improving skill sets is a move that will benefit throughout their career. He added that returning employees feel refreshed and have given more thought to their career. For companies, offering unpaid leaves makes good sense for attracting and keeping talented employees.
“My hope is that this takes off,” Dr. Garritan said. “We’re all thinking, ‘What’s my next act?’ ”
Dr. Sinar took a gap year because he _________.

A.gave up his old job
B.felt exhausted after 26 years’ work
C.wanted to travel very much
D.became interested in historical research

After his gap year, Dr. Sinar _________.

A.became more considerate in his job
B.regretted taking a “gap year”
C.was eager to explore ancient buildings
D.Improved his speaking ability

What’s George Garritan’s attitude toward the “gap year”?

A.Unhappy.. B.Positive C.Uninterested. D.Negative.

What’s the passage mainly about?

A.Whether a gap year is popular with adults.
B.How an adult plans a mid-career gap year.
C.Why a gap year is worthwhile for adults.
D.Why a gap year is challenging for individuals.
