In the Caucasus (高加索) region of Russia, nearly 50 out of every 10,0000 people live to celebrate their 100th birthday, and many don't stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren't alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans (厄瓜多尔人) of the Andes Mountains seem to share the secret of long life, too.
These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-grandchildren Even the idea of aging is foreign to them. When asked “at what age does youth end?” most of these old people had no answer. Several replied, “Well, perhaps at age 80.”
What accounts for this ability to survive to such old age, and to survive so well? First of all, hard physical work is a way of life for all of these long-living people. They begin their long days of physical labor as children and never seem to stop. For example, Mr. Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. “Why? What else would I do?” he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel system stronger.
Another factor that may contribute to the good health of these people is their isolation. To a great extent, they are separated from the pressures and worries of industrial society. Inherited factors also play some role Most of the longest-living people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.

【推荐1】Much like people whose relatives or friends have died, orphaned (成为孤儿的) elephants get by with a little help from their friends, according to a study.
Scientists in the United States and Kenya analysed stress hormones (激素) in the baby elephants whose mothers had died, expecting to find higher levels. Instead, the support of their peers appeared to reduce the orphans’ level of anxiety.
The study, published last week in the journal Communications Biology, concluded that social relationships have a psychological impact on the young elephants. Elephants have strong familial and group ties. Before the age of nine, baby elephants rarely move away more than 30 feet (nine metres) from their mothers, and even a few hours of separation lead to joyous reunion. The bond between female elephants and their young has long been thought to reduce stress.
Expecting to find that the orphaned elephants, which tend to die early at a higher rate than those whose mothers are still alive, would be more depressed, the team analysed stress hormone levels in the waste matter of 36 young elephants in the nature reserves in northern Kenya between 2015 and 2016. Twenty-five of the elephants had lost their mothers to drought or hunting between 2009 and 2013, when a rise in the demand for ivory left many elephants on the reserves motherless.
However, the researchers were surprised to find that long-term stress hormone levels were similar among orphans and elephants with living mothers. Jenna Parker, the study’s main author and a professor at Colorado State University, said their unexpected resilience is directly linked to social support from other elephants, specifically companions of a similar age. Those with more “friends” had significantly lower stress hormone levels. The results may encourage elephant orphanages to pair up animals to help them to recover from loss and adapt to future threats.
It could be a timely move as interactions between humans and elephants are on the rise, thanks in part to drought related to climate change. Experts say the increased conflict is a threat to Kenya’s 36,000 strong elephant population.

【推荐2】True happiness lies in rewarding relationships, not material wealth, according to new research. Scientists have said that a close circle of friends and family is most important for happiness, and that owning things such as iPhones, computers, being wealthy and owning a sports car do not provide the same level of satisfaction.
The study was done by psychologists at the Sahlgrenska Academy and Lund University, in Sweden. The experts analyzed articles in Swedish newspapers published in 2016 and recorded which words most often occurred in the same articles as the Swedish word for happiness. In this way, they could know our common happiness.
Co-author Dr Danilo Garcia, a researcher at the Sahlgrenska Academy’s Center for Ethics, Law and Mental Health, said, “It’s relationships that are most important, not material things that we possess, and this is in line with other findings in happiness research.”
The study, which contained more than 1.5 million words, showed that terms such as “grandmother” and personal pronouns such as “you”, “me”, “us” and “them” often emerge in the same article as the Swedish word for happiness. Researchers found that words such as “iPhone”, “millions” and “Google” almost never appear with the word “happiness”.
The study is a part of a larger research project on how people describe both positive and negative events in their lives. The researchers believe that the word analysis reflects a common perception among the members of our society as to what should make us happy.
Dr Danilo Garcia said, “Just as the Beatles sang, most people understand that money can’t buy you happiness or love. But even if we can understand the importance of close and warm relationships at a social level, it isn’t certain that everyone is aware that such relationships are actually necessary for our own personal happiness.”

【推荐3】Apps such as Snapchat already give users the ability to add dog ears, colorful hats and other images onto smart phone photos. Virtual(虚拟的)mirrors are a little different. They are designed to let users see what they would look like wearing something that they might want to buy, such as eyeglasses and earrings.
A smart mirror is an app that turns the screen of a smart phone or other mobile device (装置) into a mirror, using its camera. As users look at the image(影像), the app will make it appear as if they are wearing the object. These smart mirror Apps are becoming popular among retail(零售的))businesses, which want to get people into their stores.
Peter Johnson is with FaceCake Marketing Technologies. He said, “Virtual try-on off the ability to try on a great many objects, many more than they would be able to try on if were no such kind of App.” Recently, Johnson showed how an app called Dangle works. It lets store customers try on different earrings(耳环)without touching a single pair Dangle can be used on a computer. It uses the app's facial recognition technology to make it appear as if the user is wearing earrings. The earrings in the image appear almost real.
With Dangle, retailers can show customers all of their earrings in a short period of time---something almost impossible without technology. There are other good reasons to use the app. Trying-on goods with the virtual mirror means there is nothing to damage, lose or at risk of being stolen.
Alec Gefrides is with the American technology company Intel. “We always hear about the big store closings,” said Gefrides. “But Intel sees technology becoming more important in providing customers with a better experience.”

【推荐1】The secret of successful response
The novel coronavirus(新冠状病毒)is an uncommon threat. We don't know how bad it will be, nor do we know for how long it will spread. But we do know that it has already infected (感染) more than 18,000 people and killed many around the world. It also caused serious global economic damage. We need to adapt our responses to different countries and different parts of the same country in order to limit damage. Using data well is essential to such a successful response.
Data is key to all successful public health programs. In New York City, we raised tobacco taxes and made all indoor public places smoke free. Smoking rates declined at first but then the decline stopped. Because we had a tracking system in place, we realised that progress had stopped. So, we produced strong and direct no tobacco ads to the public. Our programs quickly reduced adult and teenager smoking, preventing more than 10,0000 deaths.
Every country facing the coronavirus disease needs to strengthen their data systems to track diseases, investigate skillfully and respond fast and successfully. Fast action will save lives and save money. But building the capacity to do this isn't free. It will cost about $1 to $2 per person per year for at least 10 years --- at least 30 billion. That's a lot of money for public health, but it's a tiny part of the amount lost when we don't know what we need to know about health threats.
Getting he data right is hardly quick and never easy, but it is always very important if we want to respond successfully, limit spread, and protect our communities and economy.

【推荐2】Two musicians from Germany are using robotic equipment to add sounds to their performances. The two-man band performs with a robot that can play several musical instruments at the same time. The robot can sound like a guitar, keyboard, drum or other percussion instrument. When performing, members of the band provide many of the sounds, but others are controlled by a computer. Once connected to wires and set up, instruments can play on their own.
One of the instruments was created from a long, self-turning wooden stick that sits on top of a microphone stand. The stick contains long strings. They are tied on each end. The strings are connected to a small wooden ball. As the stick turns, the ball hits a block on the floor, creating a sound.
The two-man band, called Joasihno, recently performed at the South by Southwest Conference and Music Festival in Austin, Texas. They describe their electronic sound as “psychedelic (迷幻的) machine” music. “Actually, we call it a psychedelic robot orchestra,” said Cico Beck, one of the creators of the group.
The group’s other member, Nico Siereg, says playing in an experimental band with robots is not the same as playing in a traditional one. “It’s a little bit different because you also have in mind that there are machines playing around you, so there’s no reaction from them,” he said. But Siereg said that in some ways, the robots actually help him improve his performance. Since the self-playing instruments are programmed, he sometimes feels freer to center on what he is playing, and at times to even play without preparation.
The musician says he can imagine similar technology having a greater influence on many different kinds of music in the future. “Technology is like a very important tool that even, very often, it’s also a very important part of inspiration,” he said. But he also expressed hope that “real music won’t die.”
In addition to performing recently in Texas, Joashihno has been busy putting on shows in Europe and in Canada. The band hopes its high-tech music “experiment” will keep reaching new people and pleasing the ears of its fans.

【推荐3】Dogs are born to socialise with people because we raise them that way. Two-month-old dogs can already recognise when people are pointing at objects and will stare at our faces when they’re spoken to—both signs that dogs have an innate capacity to interact with us through body language.
“Although individual relationships with people might influence that behaviour, at least 40percent of this ability comes from genetics alone, “says Emily Bray at the University of Arizona. “Over the course of keeping dogs, there has been a clear selection for these social skills,” she says. “It’s something that’s deep in them and that comes out at a really young age even before they have much experience with humans.”
Bray and her colleagues tested these types of skills in 375 eight-week-old dogs that were chosen to become service dogs. Bray says, “It was the earliest age when the dogs could carryout such experiments because they were only just old enough to be motivated by food rewards.”
The researchers found that pointing at food hidden under a cup helped the dogs to find it nearly 70 percent of the time. The success rate was high from the start, meaning they weren’t learning to follow pointing, but had already known to do so. In a control test, the randomly selected dogs couldn’t find food hidden under one of the two cups at a higher rate, indicating that they weren’t simply smelling it. Much of the variation in different dogs’ abilities to follow finger-pointing is explained by genetics. Using statistical analyses based on the dogs’ parents and other relatives, the researchers found that genetic factors were responsible for much of these variations.
The team also ran another experiment in which the researchers spoke “baby talk” to the dogs and found that the dogs fixed their eyes on the person for more than 6 seconds on aver-age, representing an understanding that the researchers were communicating with them.

【推荐2】Suppose your permanent residence, or hukou, was in Chongqing, you worked in Beijing and you needed to get a passport for a business trip abroad. What should you do?
You have to go back to Chongqing, which is 1,500km away, and apply to local public security authorities for the passport, because in China public services are closely linked to hukou. But a new regulation, which is part of the hukou reform, will make this annoying experience a thing of the past.
The regulation targets China’s newly introduced residence permit system, which will take effect on Jan 1, 2016. It allows people who don’t have local hukou to receive more access to basic public services in the cities where they are living. These include education, basic employment services, automobile registration, and passport and ID card application processing.
You can apply for a residence permit at the local police station, which has jurisdiction (管辖权) over the area where you live. The documents needed for the permit application include your ID card, photos and materials that prove that you have a job, a place to live, or that you are studying at an education institution.
To certify that you have a place to live, a house rental contract or property ownership certificate will do. For employment, a business license, job contract, or employment certificate can do the trick. If you are a student applying for the permit, show your student card or other documentation issued by your school.
Despite all this, maybe you are still not happy about not having a local hukou. Don’t worry. People will have a chance, as the country is reforming the hukou system further.

I am writing to express my concern about the plans to build a motorway near our village.
Haldersham is one of the loveliest villages in England. It is peaceful and quiet, and it is situated in a very attractive valley. There are also several beautiful countryside walks in the surroundings, with a view of many rare trees and plants.
Most of the people who live in Haldersham have moved here from other places, often from London and other big cities. They have bought houses here to live in a place far away from the noise and the stress of the big city. They paid a lot of money for their houses, but they knew they would get a high quality of life for it.
If the planned motorway is built, life in Haldersham will change greatly. There will be a lot of noise around us, and nobody will want to go on the walks. House prices will certainly go down, because nobody will want to buy houses in a place close to a motorway. Haldersham will become an ugly place.
I don’t think any of the people living in this beautiful village want that, and we all believe exposure to noise pollution can have a direct influence on our health. So, let’s all tell the politicians who support the motorway plans what we think about them!
Yours faithfully,
Hilary Riley

【推荐1】A mother in Northern Ireland was surprised when her son managed to greet her with a tiny "hello" at just 7 weeks old. Toni McCann said her son Cillian, now 9 weeks, has said "hello" twice. The infant（婴儿） appeared to try and unsuccessfully imitate his mother before finally managing a quick "hello" for the first time.
"He was making a lot of eye contact and that's why I started filming him, "she said. " I realized he was trying to copy what I was saying and then it just came out. "McCann said she first noticed Cillian trying to mimic（模仿）sounds at just 5 weeks old when her husband was holding him.
"This is a perfect example of modeling behaviour, Mum is coaching him to do what she's doing, "said Murray. " It's an important example of what we want all mothers to do with their baby. "
Murray said Cillian's first word is likely not the same as a l to 2-year-old's first word, where they have attached the word to some meaning.
"They don't have muscle coordination（协调, 配合）of the mouth, "Murray said of newborn infants. "It's usually a process of both learning what words mean by hearing them and by seeing mum and by trying to imitate mum over and over again. "
Murray said new mums should talk to their babies, even if the infants can't say full words yet. She also recommended letting babies "talk back" in the conversation, even if they don't have full words yet. While the video of Cillian saying hello has gone popular, McCann said she has already moved on to a new phrase for the baby. "Now I'm saying to him' I love you'. " she added.

【推荐2】Israeli company Watergen has produced an appliance that can generate clean,drinkable water out of air. The device,called GENNY, is small enough to be used in a home or office but can generate up to 30 liters of water a day.
GENNY takes air in and passes through a filter(过滤器)to remove dust and dirt. The filter is powerful enough to work with high air pollution. The air is directed through GENius,a heating and cooling process which causes water in the air to condense(凝结).This water is then passed through several more filters and minerals are added to improve the flavor of the water. Finally, the water is stored in a tank where it is continually circulated to keep it fresh. Therefore,the water produced by GENNY is often of a higher quality than water running through filtration systems attached to the city's water lines.
The technology of GENius is much better than other technologies that generate water from air. It produces four to five times more water per kilowatt-hour.Watergen has other products that use this same technology on a larger scale, the largest of which can produce up to 5,000 liters of water per day.
As an added bonus,during the water generation process, GENNY can emit clean air which is healthier for people to breathe.
At the Consumer Electronics Show in Las Vegas, GENNY was named the Energy Efficient Product of the Year. The award series recognize the world's top high-tech home products.
Last year,Watergen's large-scale products were donated to authorities in Brazil,Vietnam and India. They also assisted rescue and recovery efforts during the 2018 California wildfires and provided clean,safe water for the residents of Texas and Florida in the aftermath of the devastation caused by hurricanes Harvey and Irma.
Watergen also seeks to help protect the environment by reducing waste generated by plastic water bottles. People are called upon to put the water from GEENY into reusable bottles so that plastic ones don't get used and thrown away.

Simply Electrifying offers the comprehensive story of one of mankind's most important journeys: from a time when only a few could even imagine a world with electricity to today when, for most of us, a world without electricity would be unimaginable.
Since the birth of the modern science of electricity 265 years ago, mankind has built a great structure to produce, deliver, and use electricity, thanks to a combination of pioneering science, innovative technology, wise business strategy, and pervasive (到处存在的) economic and environmental regulation.
Simply Electrifying brings to life the stories of the people that made it all possible- from early pathfinders like Benjamin Franklin, Michael Faraday, James Clerk Maxwell, and Albert Einstein to innovators such as Samuel Morse, Thomas Edison, George Westinghouse, and Nikola Tesla. In modern times, business strategists and economic and environmental regulation driven by many, including President Franklin D. Roosevelt, Rachel Carson, and even President Barack Obama, have shaped how we use and understand electricity in important ways. Today, Elon Musk and others are on the edge of again changing the way we think about and interact with it.
Simply Electrifying is painstakingly researched and beautifully written, showing us how both profit-makers and policy-makers must use a wide-angle lens to truly understand the past and predict the future.
1. According to the passage, the book Simply Electrifying is written to tell us ______.| A．pioneering science of electricity |
| B．the significant journey of electricity |
