Human brains begin growing and developing at a very young age. They learn from the simplest experiences, which enable your children to be aware of the world. There's no denying that outdoor play helps a lot!

Times when children have to wait for their turns on playground equipment and following the playground rules by sharing, all these form components of a healthy social-emotional development. Young children develop their social-emotional skills through practice and small steps over time.

As parents or caregivers, it is fairly simple to support your child's social-emotional skills. Acts like holding him, touching him, and speaking to him and giving him loving care and attention are all helping factors. When you allow them freedom to play, it is important to follow their interests in helping build their social-emotional skills.

Difficulties in social-emotional skills can often lead to children having trouble when playing with other children. Becoming easily angry or not empathizing (理解) with other children are all signs that may point in this direction. This can in turn lead to them not empathizing with the needs of other children.

    As for the development of cognitive (认知的) skills, these develop through practice and opportunity over time. And while some cognitive skills may be genetic, most are learned through real life situations. In other words, learning and thinking skills can be improved through experiences.

    To enable them to learn, it is important that we are mindful of what our children are interested in. And this realization is only set in place once the child is given enough room and time to grow and explore.

    Depriving children of such experiences can mean that they might struggle with higher- level thinking skills. And while it is normal to keep them safe, we forget that by rushing them and cutting down on play time, we're actually causing more harm than good.

    When the natural climate changes due to global warming, it can surely affect seals. The majority of them live in the Antarctic region so as the ice is melting, their natural habitat（栖息地）can be seriously affected. These changes don't take place overnight. They can be the result of many years of additional temperatures in the area. The seals then have to find ways to adapt.

    Seals depend on the cool air currents to bring plenty of food for them. When the temperatures get higher, there is less and less food and the seal population starts to get depleted. Mothers aren't healthy enough to feed their babies. Many of them end up abandoned as the mothers have to leave to find their own source of food.

    The fact that their desire to produce young can be changed by the warmer temperatures is frightening too. It is also believed that the warmer temperatures can allow different diseases and viruses to attack the seals. This is a huge concern as they can rapidly wipe out huge numbers of seals out there.

    However, these changes in climate and temperature aren't all bad for other species of seals. Scientists have found that those living in warmer climates are producing more young due to the changes. Research also shows that the females are moving further to find food and water. When they are out of the reach of the governing males, they are more willing to accept the moves of other males in the group.

    This is good news too because it means that there will be more selection in the gene pool（基因库）for future generations. It can help the seals as a species adapt to changes in their natural environment more easily.

    The climate change problem for seals is directly linked to humans. When we take action to change what we let out into the environment, we will make positive changes for the seals. However, it is going to take a very long time to reverse（彻底改变）the effects of what has already been done.

    Houses have been getting progressively "smarter" for decades, but the next generation of smart homes may offer what two Case Western Reserve University scientists are calling an "Internet of Ears."

    Today's smart home features appliances, entertainment systems, security cameras and lighting, heating and cooling systems that are connected to each other and the Internet. They can be accessed and controlled remotely by computer or smartphone apps.

    But a group of electrical engineering and computer science professors in the Case School of Engineering have been experimenting with a new suite of sensors (传感器). This system would read not only the vibrations (震动), sounds and even other movements associated with people and animals in a building, but also any slight changes in the existing electrical field.

    While there still maybe a decade or so away, the home of the future could be a building that adjusts to your activity with only a few small, hidden sensors in the walls and floor with-out the need for monitoring cameras.

    "We are trying to make a building that is able t0 61isten' to the humans inside," said Ming-Chun Huang, an assistant professor in electrical engineering and computer science. "We are using principles similar to those of the human ear, where vibrations are picked up and our algorithms (计算程序) recognize them to determine your specific movements. That's why we call it the 61nternet of Ears'. "

    “There is actually a constant 60 Hz electrical field all around us, and because people are somewhat conductive, they short out the field just a little," Huang said. "So, by measuring the disturbance in that field, we are able to determine their presence, or even their breathing, even when there are no vibrations associated with sound.”

    Huang said they have used as few as four small sensors in the walls and floor of a room.

    As for privacy concerns, the system would not be able to identify individuals, although it could recognize people's different ways of walking.

    The first day my new teacher walked into our school in Spanish Harlem, I burst out laughing. Ron Clark was this young white guy from North Carolina who talked with a funny Southern accent(口音). He said he used to be a singing waiter. I thought, who is this guy? He's a complete joke.

    It was 1999 and I was in the fifth grade at New York City's P.S. 83. I guessed I'd spend most of the year in the headmaster's office. I'd always been a troublemaker. I'd get shouted at, and then the teachers would give up on me. I thought that's what would happen with Ron Clark.

    I was wrong. That first week, I kept laughing at him. He pulled me out to the hallway and said I'd better shape up(表现好). "Tamara," he said, "you're a smart kid. You can do better."

    He told me I was a natural leader and that I'd go far in life if I started studying hard. I was mad at first, but then something happened: I began to respect him. There were 29 students in our class, and it didn't take long for us to realize that Ron Clark was no ordinary teacher.

    Like most teachers, he had lots of rules: Treat each other like family. Don't cut in line. But the real difference was how concerned he was. Mr. Clark ate with us in the lunchroom instead of going to the teachers' day-room. At first, my friends and I were thinking. What is he doing?

    He asked us what was going on in our lives. Between classes, he came outside with us, and we taught him how to jump rope. When it snowed, Mr. Clark, who'd never seen snow before, threw us with snowballs, and we threw him back.

    Before coming to P.S. 83, he taught at Snowden Elementary in his hometown, Belhaven, North Carolina. His parents were DJs(流行音乐节目主持人)at dance clubs, so he grew up with music and energy. He wanted a life of adventure, he told me, but his mom encouraged him to ask for a position at Snowden when one of the teachers passed away. Mr. Clark ended up loving it. He came to Harlem because he'd seen a TV show about our troubled schools and the lack of qualified teachers. He wanted a challenge. Boy, did he get one.

    China's box office numbers continue to grow rapidly. It is estimated that the revenues(收入) may pass the U. S. market's as soon as this year. However, this cinematic party could be over just as it's getting started. Some companies are working to convince consumers that the ultimate viewing experience is not on the big screen.

    Instead, it's on the small ones that are already in their pockets-thanks to the technology of virtual reality.

    Already, VR experience centers are popping up in major cities like Beijing and Shanghai. They give customers the opportunity to watch VR movies or play VR games for about the same price as a discount movie ticket. Online video sites, meanwhile, are also moving into the VR field. Some of them, like Youku, have launched(推出) their own VR apps and channels.

    China has more than 700 million smartphone users. A large percentage of them are already more than willing to download and watch TV shows and even full-length movies on their handsets. This potentially makes them more likely to embrace VR content than Americans and Europeans.

    But in fact, it's not just Chinese companies and video websites that believe VR will pull viewers away from movie theaters. International production companies that, for years, have made block busters (大片) for cinema audiences are also warning that disruptive change is around the corner.

    Maureen Fan, chief executive of the Silicon Valley VR start-up Baobab Studios, after bringing her company's animated VR short Invasion to the Shanghai International Film Festival last year, concluded that the field had been evolving much more rapidly than she expected. "What I thought would take ten years has happened in one or two," she said. However, she also noted that the industry needs more people who can create great stories to move VR beyond a niche product(小众产品 ) and into the mass market. "The technology is already there. What continues to be lacking is good content," Fan said. "There's a certain amount, but we would love to see more."

    It's one of the most common questions adults ask children: what do you want to be when you grow up? Although childhood is supposed to be fun, kids also discuss important topics regarding their futures. Now, a new study finds that children who set big goals regarding their future status and education often set themselves up for success as they age. 

    The findings, published in the Journal of Personality and Social Psychology, are the first to reveal a connection between life goal development and future success in school or the workplace. Rodica Damian, an associate professor of psychology at the University of Houston, and other researchers discovered that as children grow up, their goals naturally begin to change. However, as some childhood goals fall away, other goals related to a family stay strong. These include being close to relatives, building more friendships or finding a romantic partner, and even becoming more involved in your community or helping others. 

    During the study, researchers compared how their goals evolved as children moved from adolescence to adulthood and how a person's goals impacted their success in school and as an employee later on. Overall, a child's goals focusing on their education and future status were the most consistent predictors (预测因素) of income in adulthood. Simply put, when a child dreams big about doing well in school or achieving great success as an adult, these goals accurately paint a picture of how successful these children will be. So, the message is simple: dream big and dream of success, kids! Those goals can drive you to success when you grow up! 

    "Our work proves a strong connect ion between a child's life goals, educational achievement, and future occupational outcomes. This information is valuable for parents and educators who can use it to encourage children to set ambitious goals. Additionally, it helps develop strategies to support individuals in achieving their goals and reaching their full potential," Damian concludes.
