The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on well with their parents, which is the opposite of the popularly-held image of unhappy teenagers locked in their room after endless family quarrels.

    An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it had ever been in the past. “We were surprised by just how positive today's young people seem to be about their families,” said one member of the research team. “They're expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds: they want a car and material goods, and they worry about whether school is serving them well. There's more negotiation(商议) and discussion between parents and children, and children expect to take part in the family decision-making process. They don't want to rock the boat.”

    So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-year-old Daniel Lazall. “I always tell them when I'm going out clubbing. As long as they know what I'm doing, they're fine with me.” Susan Crome, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I'd done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”

    Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion(反抗) is not rooted in real facts. A researcher comments, “Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over. ”

    Lying alongside mountains of smelly garbage under the South American sun, Cateura is a long way from the conservatories of Prague or Vienna. Yet the township, which grew out of Paraguay's largest dump(垃圾场), is gaining a reputation as a hothouse for musical talent and for its youth orchestra(管弦乐队) that plays instruments made from garbage. "The world sends us garbage. We send back music," says Favio Chavez, leader of the "Recycled Orchestra," during a recent visit by the group to Los Angeles. Orchestra members, poor children from Cateura, play violins fashioned from oven trays and guitars made from dessert dishes. The orchestra provides the youngsters an outlet and an escape, a chance to go beyond the mess of their slum(贫民窟) through the music of Mozart, and even Sinatra. "In the beginning, it was difficult to play," says the l0-year-old violinist Celeste Fleitas." But Favio helped me learn over time. From Favio, I have learned to be more responsible and value the things I have."

    The destination for more than 1,500 tons of waste each day, the community has no safe drinking water and little access to electricity or sanitation(卫生设施). Illiteracy is severe, and the children of the township often fall into drugs, violence and crimes.

    Favio Chavez, a musical talent, came to Cateura as an environmental technician in 2006 and started a youth music school. He knew shop-bought instruments were beyond the means of villagers whose sheds are worth less than a violin, so he approached a carpenter to make some out of waste from the dump.

    The orchestra caught the eye of Paraguayan filmmaker Alejandra Amarilla. She uploaded a short piece of the orchestra to YouTube in 2012, hoping to secure crowdfunding for what would become Landfill Harmonic, a documentary released across the United States this month and promoting the youngsters on a tour of the world's music halls later on.

     Stephen Hawking is perhaps the world's most famous living physicist. To the public, he's best known as an author of bestsellers such as The Universe in a Nutshell and A Brief History of Time, which have brought an appreciation of theoretical (理论上的)  physics to millions. He is regarded as having one of the brightest minds on the planet. But outstanding astrophysicist (天体物理学家) Stephen Hawking has admitted that he did not learn to read until he was eight years old.

    In a public lecture at the Royal Albert Hall, Professor Hawking also admitted that he was not active in studying while at Oxford University, where he studied physics, and that only the news that he might die young from motor neurone (运动神经元) disease made him focus on his work.

    Professor Hawking said, “My sister Philippa could read by the age of 4 but then she was brighter than me.” He said that he was common at school and was never further than halfway up his class. “My classwork was very untidy, and my handwriting was very bad in the teachers' eyes,” he said. “But my classmates gave me the name Einstein, so probably they saw signs of something better.”

    But he said that it was when doctors told him that he probably only had a few years to live at the age of 21 that he began to focus on his work, which resulted in some of his early achievements. He said, “When you are faced with the possibility of an early death, it makes you realize that life is worth living and there are lots of things you want to do.” Hawking serves as Lucasian Professor of Mathematics at the University of Cambridge, where he continues to contribute to both high-level physics and the popular understanding of our universe.

    I remember my childhood summers fondly, as many of us do. Those golden days in which I would leave the house after a still sleepy, leisurely breakfast and come home only for lunch in the middle of a day spent entirely outdoors. We did not live in town and, thus, playmates were limited to siblings (兄弟姐妹) and the cousins who lived down the road.

    Our backyard became the playground in which our imaginations would run wild—turning those few acres into magical forests, the creek (小溪) into a violent river and our trusty dog, Rex, into the many roles of horse, monster and any other creature that we children did not want to play. By the end of the three months of summer break we were sunburned from our hours in the sun, full of the memories of a thousand magical moments and bonded to our siblings in a way that winter's forced hibernation (冬眠) never seemed to connect us.

    Today, I live on the same acreage that I did as a child. My children have the blessing of having the same grassy patches to scratch their bare feet as they run through it, the same creek to stomp(跺脚)through, and not the same dog—but their very own energetic pup to imagine away the days with.

    However, this is not the same world as it was twenty, thirty years ago. There are screens everywhere in the house to demand attention—televisions with hundreds of channels, computers with access to a thousand entertaining sites, tablets stocked with apps. There is also no longer the expectation of a stretch of an unscheduled three months. Their school friends tell competitive stories of carefully planned vacations, spending time traveling to all of the local attractions—various parks, the zoo, the science center, all of the festivals which come breezing through town. On the very first day of school they will be asked to list their favorite activities of the summer and no longer are these lists filled with things like finding wood to make a bridge over a creek or a day spent in imaginative play with their siblings. The lists are now full of trips, overscheduled days and “camps” that no longer offer a stay in nature.

    Our children have become used to being entertained every minute. In our house, we have limits on electronics and kick the kids outside on a nice day. Even as we try as parents to set limits and get our children out in nature, the new cry of childhood seems to be “I'm bored,” which is not really just meaning “I'm bored,” “but “Please find something to entertain me, as I no longer can entertain myself even for a short period of time.” Our children no longer know how to sit in silence, entertain themselves while even waiting for a few minutes and have lost the awe of nature as they have become addicted to screen time.

    We have made a choice in this household to do what is no longer expected of children in many households—we will ensure that there are days of “boredom.” We refuse to spend our days scheduling our children's every hour. There will be many days with no plans at all, when they will be sent outside with only the grass and the trees and their own imaginations to entertain them.

    The screens will be turned off and our children will find that times of quiet can be just as or even more entertaining. They will bond with their brother and sister, making memories that they will replay in their minds well into adulthood. Even though sunscreen will be religiously applied, they will leave summer with sunburned and scratches coming from climbing trees, stomping through creeks and chasing the dog in the field.

    This summer I will be giving my children the greatest gift of all—boredom. For inside boredom is the gift of getting to know your own mind, of finding comfort and joy in nature and in the realization that the greatest gifts are experience, not things.

    “He is the best choice for goodwill ambassador.” Indian movie fans in China say.

    Indian actor Aamir Khan has got his major celebrity status in China. Aamir Khan was in China last week to promote his latest Hindi film Secret Superstar. During his weeklong stay, first in Shanghai and then in Beijing, the Indian actor also found out that he has become a major celebrity in a country where Hollywood's reach has been traditionally limited.

    Some local analysts compare his star status in China to that of Hollywood actors Tom Hanks, Tom Cruise and Leonardo DiCaprio. Others wonder if Khan is an activist actor. Still others describe him as a feminist（女权主义者）. The Chinese media seem to have called him Mishu, or Uncle Aamir. The surprising rise in popularity of the 52-year-old Bollywood star is owing to his striking movies. At more than 1 million, Khan has the most followers as an Indian on Sina Weibo, the country's Twitter-like platform.

    Secret Superstar had made more than 400 million yuan（$63 million）earlier this week. The story of a teenage Muslim girl's fight against ugly patriarchy（父权制）to realize her dreams was released in China on Jan 19.

    Last year, his film Dangal, inspired by the real journey of an Indian wrestler through a conservative landscape to turn his daughters into world-class athletes, had made nearly 1.3 billion yuan.

    In 2011, Khan's work first got major attention from Chinese moviegoers with Three Idiots, which was released in India much earlier. A statement on India's orthodox education system, similar to that of China, the Hindi film went along with the local audience. Film critics and fans alike recommended it to their friends.

    Some film critics say the education systems, gender discrimination（性别歧视）and domestic violence（家庭暴力）that Secret Superstar shows are among similarities of social issues in India and China. A series of “masterpieces” have made Khan an effective brand in China, in addition to his movie marketing and film devotion.

    Age has never been a problem for 16­year­old Thessalonika Arzu­Embry. After all, she's already got her master's degree.

    The North Chicago­area teen started homeschooling at the age of 4. She began having an influence on others soon after. When she was 6 years old, she was an inspirational speaker at an organization called Tabitha House Community Service, a shelter for people who were forced to leave their homes due to the situations such as earthquake, flood and other natural disasters.

    At the age of 11, she graduated from high school and then earned her bachelor's degree in psychology in 2013. She completed those classes online as she was traveling for church events and leadership meetings.

    She doesn't stop there, though. The teen plans to focus on aviation psychology(航空心理学) for her further study, a decision inspired by her father who is a pilot. She grew up around airplanes and took fights all the time. Her goal is to use it to determine whether pilots are dealing with problems that could have deadly results once the plane takes off­a topic that has been in the news lately. For her, it's a mix of two of her interests.

    In her free time, Thessalonika enjoys playing tennis, swimming and being active in her youth group at church. She also has three self­published books, which are on her site. Jump the Education Barrier is written to help students finish college, and in the future aims to help business owners with trends. Her third book The Genius Race, has a wider appeal. It is designed to help people to be geniuses in various areas of life.
