While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

         Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

Fellow Robots is one company bringing social robots to the market. The company's “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

          The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.

    Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.

    At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn't eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins. The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person's food.

    Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don't, they can also take vitamin pills.

    My mother raised me as best as she could, taking on odd jobs in the neighborhood for money. Still without a father to tell me how to act and what was expected of me, I felt lost. I wandered for years and got involved with tough guys on the East Side of New York. They would fight madly over a dropped coin. They would steal to get what they wanted. I wanted to be like them.

    It was lucky for me that I left the city and entered a world of discipline (纪律), after following my mother's advice. During three years of military service, I had time to rethink my life, and my thoughts often ran to my mother. I realized suddenly just how much of a heartache I must have been to her, how little I had noticed her suffering. When my father left this world, my mother was completely alone. To support us, my mother cleaned apartments and took in washing and ironing from the neighbors. And as she worked hard at this labor, she kept her head high. Each week she would bring a pile of books home from the library and read to us. My mother had wanted nothing more, than for me to turn into an honest responsible man. But I had acted against her. Finally, almost too late I had the sense to feel shame.

    Ten years passed and I returned to the apartment on the East Side. I knew I wouldn't fall back in with the wrong people, although I still wasn't sure where I was heading. My mother, I could tell, was worried about me. In my neighborhood, to become a police officer or a firefighter was a mark of significant social success and achievement. For me it was an opportunity for a real start in life. I wondered if I was up to it, but I knew that it was time to try. When I found myself in the big hall raising my hands to take the firefighters oath (誓言) of office, my mother was sitting a few rows behind with a smile of relief. She knew that at last I was off on life's road and moving steadily. Her smile said, “My job is finally done.”

    It's Friday night. You're looking through your Instagram (a photo-sharing app) feed when you see it: a photo of your friends hanging out without you.

    Why didn't anyone invite you? What are they doing later? Should you text them? What if no one responds (回应)?

    Sounds like a typical case of FOMO.

    FOMO, or "fear of missing out", is a form of anxiety that causes people to feel like they're missing out on something. The word was added to The Oxford English Dictionary last year. But just how serious is FOMO?

    According to a study by a US research organization, JWTIntelligence, 47 percent of teen millennials (those who are 13-17 years old now) feel upset or nervous when they learn that their friends are doing something they're not. And 41 percent said they spread themselves too thin, trying to do too many things at one time to avoid FOMO.

    Today's technology is a big cause of FOMO, according to Jonathan Pochyly, an adolescent psychiatrist (青少年精神病学专家) at Lurie Children's Hospital in Chicago.

    "Technology is one of the things that makes life special for adolescents these days," he explained.  

    "There's a lot of focus on what everyone else is doing. It became a trend, so there's pressure to keep up with it."

    As social media (社交媒体) feeds are always updating us with our friends' activities, it's easier than ever to feel left out. So what can we do?

    To fight against FOMO, Jones freshman Emmy Brewer just calls people and talks to them.

    "I'd be upset for a bit, but then I'd realize that I should be reaching out to them," she said.

    Oak Park and River Forest High School senior James Cullinane said he fights off FOMO by living in the now.

    "If I'm hanging out with my friends, or just sitting at home on my couch, I think it's best to stay off social media and focus on what I'm doing in the moment," Cullinane said.

    While FOMO will continue to affect (影响) teenagers in the future, Pochyly said that he believes these feelings are just side effects of growing up.

    "These types of interactions (交往) with people are … a function (功能) of kids being more independent, looking for connections with other people, moving away from just being a child in a home, and moving toward adulthood," he said.

    The Ministry of Construction has released the names of the first group of 20 national parks, including 9 Suzhou classical gardens: Zhuozheng Garden, Liu Garden, Wangshi Garden, Huanxiu Villa, Lion Grove, Yipu Garden, Ou Garden, Tuisi Garden and Canglang Pavilion.

    National parks refer to the famous city parks and gardens. Suzhou classical gardens are parts of China's precious cultural heritage (遗产) (all the 9 gardens are on the list of World Cultural Heritage) as well as a necessary part of the life of Suzhou citizens, not to mention they are also world-famous tourism resorts (胜地). In fact, their unique historical and cultural background serves to contribute to their ranking among national parks.

    The earliest classical gardens in Suzhou can date back to the Song Dynasty. However, the gardens impress their visitors not only with their age-old history but also with their delicate scenes, particularly Canglang Pavilion, Zhuozheng Garden, Lion Grove and Liu Garden, the most famous four that represent different styles of dynasties of Song, Yuan, Ming and Qing.

    In 1978, an imitation（仿造物） of a Suzhou classical garden was set up by Chen Congzhou (the author of the book Suzhou Classical Gardens) in the City Museum of Art in New York, US, which was the first time ever to directly introduce Chinese ancient architecture to Westerners.

    It was May 23, 2016. Arnot, the 32-year-old mountain guide, reached the top of Everest without the use of oxygen (O2) equipment. It was achieved after seven years, three previous attempts, and fourteen straight hours of climbing.

After 15 minutes at the top, Arnot began her descent (下坡). Eight hours later, she reached the camp at 7, 600 meters and became the first American woman-and only the seventh woman ever—to successfully reach Mount Everest without oxygen equipment.

    "There are so many reasons for her impressive achievement, especially the physical and emotional efforts that she has put forth over the years to make this happen," says the professional climber and photographer Richards, "The mental courage that it requires is something very few people have."

    Arnot didn't start climbing until she was 19 years old. Money was tight in her family, and climbing mountains never occurred in her mind. After graduating from college, Arnot was invited by her friend to climb a mountain. "It totally changed my life," says Arnot. I always know that if you want something, you can achieve it, but knowing what you want is a whole different thing," she says. "I am athletic but not competitive. After my first climbing, I knew immediately that mountains are what I want—as that is where I felt home for the first time in my life."

    After that first climb, she devoted herself to learning how to climb and move through mountain. It was during her second trip to Everest in 2009 that she first set her sights on a no-oxygen attempt. However, while hiking into Everest Base Camp that year, she hurt her leg and wasn't able to climb without oxygen. In 2013 she nearly made it to the top, but was forced to take oxygen at 8,504 meters while helping another climber.

    When Arnot finally stood at the top Everest, she called her best friend, "I reached the top and I'm not using any oxygen." Then, tears began to stream down from her eyes. So much of Arnot's life has been about pushing the limits of her abilities, and in this case, she's also pushed up against the outer limits of the human spirit.
