2 . We have all experienced how easy it is for a smile to light up our day, improve our emotions and make it easier for us to recover from illnesses. But do you also know that smiling improves your chances of success in many aspects of your life?

Studies have shown that people are more likely to think that a smiling person is more confident than others. Smiling will inspire your boss to trust you on-a particular project. Standing in front of a group of people, a confident smile on your face indicates knowledge, competence. trustworthiness, and ability to carry out tasks efficiently. It also opens up the way to higher job earning opportunities.

If you meet a person for the first time and walk into the restaurant, the person is seated by the table, looking sad on the face. What would be your first thought? Either the person regrets the meeting or the person is troubled by other issues. The chances are more likely you wouldn't want to see the person anymore. Smiling makes a great first impression on anyone. Studies have shown that people are more likely to remember a person who has a friendly and sweet smile. This is because no one wants to have to deal with a person who is always worried. It is also a great way to ensure that you get callbacks from job interviews and other potential meetups.

When you smile, neurotransmitters, materials that are anti-stress, are released from your brain. They spread throughout the body,causing a happy feeling to take over the negative emotions Being positive gives you enough enthusiasm to go ahead and make more use of your day and be productive. In recent researches, it has been found that people who were unhappy with their work-life were less productive than others who loved their jobs.An individual who is not happy at what they do is unwilling to put in the efforts needed to go beyond the average. While the other who is positive is more likely to carry on more tasks and is more productive, gains more experience,and gets promoted more easily.

But when you are in an environment that is sad or pessimistic, it isn't easy to remain happy and optimistic. If you are caught up in a situation where something had gone wrong, and you are having a heavy heart, try looking for reasons to be happy,smile, and watch your day begin to change positively.

Do not forget that when you smile, you are not only making your day better but someone else's too. A smile is what it takes to make all the difference.

4 . People today are not unfamiliar with term such as "going eco-friendly" and "sustainable lifestyle". However, there exists a group of sceptics（怀疑论者）who believe that going eco-friendly is merely a fad（一时的风尚）. I disagree with this viewpoint, Going eco-friendly is not merely a fad and it does, in fact, change the beliefs and attitudes of people.

The long-term presence of environmental organisations shows the efforts that people have made towards going eco-friendly. Organisations such as World Wildlife Fund advocate people to go eco-friendly. The high involvement of the organisations and the participants is thus a strong indicator that going eco-friendly is not merely a fad but a trend that can last decades.

Another strong indicator is the emergence of sustainable products in many industries, such as organic produce and electric vehicles. The consumer demand, coupled with eco-conscious（环保意识的）businesses, is behind the sharp increase in such products. This shows a shift in the beliefs and attitudes of people towards adopting a sustainable lifestyle. Thus, it seems quite certain that going eco-friendly is not merely a fad.

While some people who broadcast their eco-friendly practices are criticised for just hoping to project an eco-conscious image, there are a number of celebrities who have been practising the zero-waste lifestyle for years. For those who do so for years, and not mere days or months, it is indeed a commitment that can only come with a true change in beliefs and attitudes towards caring for the earth.

The call to save the earth looks set to stay. With the development of technology and the appearance of many platforms advocating going green, people are more willing to change their beliefs and attitudes when they can learn about and appreciate the positive impact of the work of different environmental organisations and individuals. It is hoped that these effects will go a long way in ensuring that our planet will remain a suitable place to live in.

5 . There's nothing difficult about how to act at a concert. It' s mostly just common sense: the music needs silence, so the audience keeps silence; both the musicians and the audience want to concentrate on the music, so listeners stay put during a performance.

    1     You can breathe; you can shift your body in your chair. You can respond to the music, but your response will be inward, which means emotion without motion (运动).The basic idea is to help each other focus on the music. Making noise or walking around can distract(使....分神)other listeners, and it may interfere with (干扰)the musicians' concentration.     2     In other words, it's easy to forget that at a concert the performers can see and hear the audience! Your attention and silence will help the musicians to perform better. They can feel your concentration, and it inspires them to give their best.

A common concern of listeners at classical concerts, and one of the main difficulties in enjoying the music, is the terrible fear of clapping in the wrong lace. It's no wonder the audience is afraid: Classical musicians don't usually make clear what they expect of the audience.     3     That is to say, if the music stops, people give a big hand. But in classical music, you are supposed to wait to the very end of the very last ending before you clap.

    4     How do you tell when a piece of music is really over? Quite often a classical piece has several sections (小节),each with its own ending, and it can be hard to tell which ending is the eventual ending, the one you're supposed to clap for. How do you know when it's really the end of the whole thing? Don't worry.     5    

7 . In 1953, when visiting his daughter’s maths class, the Harvard psychologist B.F. Skinner found every pupil learning the same topic in the same way at the same speed. Later, he built his first “teaching machine”, which let children tackle questions at their own pace. Since then, education technology (edtech) has repeated the cycle of hype and flop (炒作和失败), even as computers have reshaped almost every other part of life.

Softwares to “personalize” learning can help hundreds of millions of children stuck in miserable classes—but only if edtech supporters can resist the temptation to revive harmful ideas about how children learn. Alternatives have so far failed to teach so many children as efficiently as the conventional model of schooling, where classrooms, hierarchical year-groups, standardized curriculums and fixed timetables are still the typical pattern for most of the world’s nearly 1.5 billion schoolchildren. Under this pattern, too many do not reach their potential. That condition remained almost unchanged over the past 15 years, though billions have been spent on IT in schools during that period.

What really matters then? The answer is how edtech is used. One way it can help is through tailor-made instruction. Reformers think edtech can put individual attention within reach of all pupils. The other way edtech can aid learning is by making schools more productive. In California schools, instead of textbooks, pupils have “playlists”, which they use to access online lessons and take tests. The software assesses children’s progress, lightening teachers’ marking load and allowing them to focus on other tasks. A study suggested that children in early adopters of this model score better in tests than their peers at other schools.

Such innovation is welcome. But making the best of edtech means getting several things right. First, “personalized learning” must follow the evidence on how children learn. It must not be an excuse to revive pseudoscientific ideas such as “learning styles”: the theory that each child has a particular way of taking in information. This theory gave rise to government-sponsored schemes like Brain Gym, which claimed that some pupils should stretch or bend while doing sums. A less consequential falsehood is that technology means children do not need to learn facts or learn from a teacher—instead they can just use Google. Some educationalists go further, arguing that facts get in the way of skills such as creativity. Actually, the opposite is true. According to studies, most effective ways of boosting learning nearly all relied on the craft of a teacher.

Second, edtech must narrow, rather than widen, inequalities in education. Here there are grounds for optimism. Some of the pioneering schools are private ones in Silicon Valley. But many more are run by charter-school groups teaching mostly poor pupils, where laggards (成绩落后者) make the most progress relative to their peers in normal classes. A similar pattern can be observed outside America.

Third, the potential for edtech will be realized only if teachers embrace it. They are right to ask for evidence that products work. But skepticism should not turn into irrational opposition. Given what edtech promises today, closed-mindedness has no place in the classroom.

8 . Raising just one child can be a tough job for any parent, which is why this woman is being honored for taking in more than 600 children over the course of five decades. 75-year-old Linda Herring from Johnson County. Iowa has been tirelessly providing food, clothing, love» and medical care to hundreds of adopted kids since the 1970s.

When Herring first began adopting kids, she was also running a home daycare and working as a night custodian（监护人）in a local high school. Additionally, she volunteered as a first responder for 50 years of her life.

Out of the hundreds of adopted kids that Herring has taken under her wing, many of them experienced a range of medical conditions and special needs-but that never prevented Herring. Linda mostly adopted young children and children with special medical needs and kept boxes of clothes in her garage, piled to the ceiling, labeled by size and gender. No one had to worry about a child going without clothes at Linda’s, even if they arrived with nothing but what they were wearing.

Anthony Herring, who was just 3 years old when he was adopted into Linda’s family, described his mother like this： "It’s hard to say in words her impact. She was always available and ready for a child in need. " These kids were usually taken from a traumatic（受到创伤的） situation and she’d take them in, providing a warm bed, clean clothes» warm meals, and love. She also worked hard to keep families together. Helping biological parents make the changes needed to be able to keep their children. She always makes sure a new child in her home was given a professional photograph that was placed on the wall in the living room. "That seems like a small thing, but it helps them feel like they’re at home.”

9 . My Biggest Challenge

As a writer on an adventure sports magazine, I’d always fought shy of doing the adventurous stuff myself, preferring instead to observe the experts from a safe distance and relay their experiences to readers in the form of written language. Thus, when I was challenged to take part in a mountain climb in aid of raising money for charity — and to write about it afterwards — I was unwilling, to say the least.

I was lucky enough to have a brilliant climbing coach called Keith, who put me through my paces after my daily work. He gave me knowledge about everything from the importance of building muscle groups to how to avoid tiredness through nutrition. It quickly became apparent that the mechanics of climbing were more complex than I had imagined. There was the equipment and techniques I’d never even heard of, all of which would come in handy on the snow-capped peak I’d be climbing.

Aware of the challenge, Keith made a detailed action plan and I forced myself to stick to it, doing a daily workout at the gym and going on hikes with a heavy pack. I perfected my technique on the climbing wall and even went to climb the mountains to get vital experience. My self-belief increased alongside my muscle power and I became confident about finishing the climb.

All too soon I was on a plane to my destination. On that day, when I looked up at the mountain, I thought of abandoning it. But then I remembered all the hard work I’d done and how disappointed Keith would be if I gave up at the last minute-not to mention letting down the charity and the sense of failure I’d experience myself. With a deep breath I gathered my equipment and headed out into the sunshine to meet the rest of the group.

And as I sit here now, tapping away on my laptop, I’m amazed at the details in which I can recall every second of the climb: the burning muscles, the tiredness, the minor problems along the way. Could I have been better prepared? Possibly. Would I be back for another go? Thankfully not. The feeling of being excited when I stood on top of the world is a never-to-be-repeated experience but one I will enjoy forever nevertheless.

10 . Liu Jichen, founder and CEO of Clear Plate®, designed a mini-program that recognizes empty plates and rewards users with points. These points can be exchanged for gifts like books and cellphones, or better yet, they can be used to purchase charity meals donated to poor children in rural areas of China.

In 2016, Liu, a then student of Tsinghua University, noticed a popular campaign called “Leftover Party”, where people brought their leftovers to eat together, intending to raise awareness of food waste. Liu and his classmates organized one such event, which was attended by hundreds of people. The success encouraged him to spread the concept of reducing food waste to a wider audience.

The idea of a mini-program struck him at a dinner in 2017 when Liu dined at a restaurant, which rewarded diners who finished off their food. Liu found that the restaurant would give these diners a card every time and offer them small gifts when they collected a certain number of cards. “Everyone who values food can enjoy a sense of gain at a lower cost,” Liu said, noting that such an idea could be realized online.

He formed a team to work on the project. Yet it was quite a challenge for the AI system to identify the uploaded photos. Liu and his team, assisted by more than 1,000 others, spent half a year collecting over 100,000 samples across the country to train the digital brain.

“There were so many uncertainties in research and development. For our team members, the biggest challenge was whether we were confident enough to complete it,” Liu said. They not only achieved their goal, but now, the mini-program has more than five million registered users. “We hope to inspire everyone to take action against food waste and to contribute Chinese wisdom and solutions to global food security challenges,” he added.
