New research suggests that there are only four basic facial expressions of emotion. However, how these expressions are understood might depend on where you are from.

    Research by scientists from the University of Glasgow in the UK has challenged the traditional view of how the face expresses emotions. Many scientists had believed that there were six basic emotions that people from all cultures recognized. These were happiness, sadness, fear, anger, surprise and disgust(厌恶). However, the University of Glasgow's work now suggests that the human face only had four basic expressions of emotions. This is because some pairs of emotions are impossible to tell apart, especially when they are first shown on the face. Fear and surprise, both share wide-open eyes. The facial expressions for anger and disgust also look the same.

    So if our faces are only able to express four basic emotions, how do we communicate much more complex feelings? The study found that the way expressions are understood is different in different cultures. Lead researcher Rachael Jack was studying this because “facial expressions were considered to be universal”, she explained. However, while looking at how people from the East and West recognize different parts of the face, they found that although there are some common features across cultures, the six basic facial expressions of emotion are not recognized universally.

    “We said we don't know what a disgust face looks like in China, so the best way to go about that is to make all combinations of facial movements and show the Chinese people and ask them to choose the ones they think are disgust faces.” With the software they developed, they discovered that in the early stages of signaling emotion, fear and surprise, and anger and disgust, were often confused. Jack explained that this development of facial expressions is related to biology and social situations.

    What has caught people's interest is the cross-cultural aspect of the work. “This study shows which emotions we share, and which are different in different cultures,” Jack said. This finding could help us develop new communication technologies, for example ones that use video-calling programs like Skype. When you talk to someone in Japan in the future, a programme could “read” your facial expressions and then “translate” them for the Japanese person. The Japanese person would see the Japanese facial expression on their screen. In this way, people from different cultures could understand each other better.

    It was the night before my election. I was running for Sophomore Vice President.

    I had prepared a performance for the election--a funny boxing match. The fight had popular moves as seen in Dodge Ball, Iron Man, and Super Smash Brothers. In the end, I would perform my famous move, the Power-Punch from Hot Rod.

    My friend Cheyenne and I rehearsed (排练) the fight for hours, but the fight would not be a fight without music and sound effects. This is where my brother came in. He stayed up all night to work on that soundtrack. And when my computer's disk burner (刻录机) went out at 6 in the morning, he spent a college student's week's worth of incomes to replace it.

    Why would he go into all that trouble? Because he knew that out of all the other important things he could be doing, this was imperative to me. He knew because it was once important to him. Having graduated from Layton High just a year earlier, he knew what it was like to be in the center of people's attention. He knew how fun high school could be, and he wanted me to have a great experience.

    I ended up losing the election, but that day changed my world forever. The lesson my brother taught me became my most important belief. But it wasn't until I had a similar opportunity that I really understood why he cared so much.

    What did it take for me to understand? It was the performance. The rest of the cast and I would rehearse every day after school for 6 months all for what? The chance to perform a play eight times. As I came out on that stage for the first time and listened to the laughter, I was filled with joy. By the end of the play, the audience broke into tears, and so did we. What happened? We had the sweet opportunity of giving them an unforgettable theatre moment -- a moment to laugh, reflect, and shed tears.

    Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son. Suddenly he seemed to be talking far more to his friends than to his parents. "The door to his room is always shut." Joanna noted.

    Tina and Mark noticed similar changes in their 14-year-old daughter. "She used to sit in my arms on the sofa and talk with me," said Mark. "Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which."

    Before age 11, children like to tell their parents what's on their minds. "In fact, parents are first on the list." said Michael Riera, author of Uncommon Sense for Parents with Teenagers. "This completely changes during the teen years." Riera explained. "They talk to their friends first, then maybe their teachers, and their parents last."

    Parents who know what's going on in their teenagers' lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental (思想的) break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.

What better way to experience the history of a site than to have a hand in actually preserving it? This was the thought behind the founding of Adventures in Preservation (AIP) in 2001. The nonprofit's founders. Judith Broeker and Jamie Donahoe, were both long time preservationists and world travelers. They had seen a great many buildings in poor condition, as well as buildings that had been "restored" without the benefit of conservation expertise.

Twelve years on, they are still involved in the day-to-day management of the organization, supported by a volunteer staff located around the world, Judith's favorite projects have long been the ones in Eastern Europe, and she enjoys opportunity to travel there each year. She, along with anyone else who's joined an adventure, always quotes their fellow jammers, as they're called, as the highlight of each project. The groups are made up of people from all different ages, occupations, and cultures. Yet each time, they form a strong bond and work so well together that the work becomes fun. Which, after all, is the point of a working vacation, no?

Raising understanding of people's own heritage(遗迹) is another part of AIP projects. In many places, there is so much focus on the news that not only are heritage buildings being lost but so are the traditional building skills needed to keep them. By providing training and raising awareness of the importance of their heritage, AIP is helping keep both alive.

Next year, AIP has projects in Europe and the US. There will be even more projects the following year as projects currently under development in Ghana, Armenia, Ukraine and the US come on line. Each project is also an opportunity for travel, adventure, and personal growth, and AIP welcomes people from around the world to join a project and" "jam" with them.

Fans of art believe that its main purpose is to make us look at life from many different angles. When it comes to Cubism(立体主义), however, the artists of this era wanted us to look at life from every angle. 

The father of Cubism, Spanish artist Pablo Picasso, is among the art world's most famous names. Like many other great names before him, he felt restrained by the rules of his teachers and decided to do something: break them. 

Early in his painting career, Picasso realized something important about how people view and remember scenes of beauty. When we look at a subject, we don't just see it from one angle, as many paintings appear. Instead, we study the subject from a number of different angles, heights and viewpoints. This is the aim of Cubism: It portrays(描绘) subjects from a wide range of angles; it doesn't force us to see things as the artist viewed them at the time he or she painted them. To bring his visions to life, Picasso and other Cubists took the most basic components of a subject and rearranged them in a way which let us see it in full detail. 

"By breaking objects and figures down into distinct areas, Picasso aimed to show different viewpoints at the same time and within the same space," in the words of the Tate Institution. Or as Lithuanian—born Cubist Jacques Lipchitz once put it: "Cubism is like standing at a certain point on a mountain and looking around. If you go higher, things will look different; if you go lower, again they will look different."

Cubism stood out as it was an art movement which didn't just rely on the artist to share their vision by painting what they saw. As cubist paintings mainly show their subjects in a deconstructed form, this means that viewers must use their imaginations to find the missing pieces for themselves. As Guardian art critic Johnathan Jones noted, this is part of the beauty of enjoying Picasso's works. "If you can relax your gaze(凝视)enough and just enjoy the painting long enough, something really amazing happens. Your mind produces a solid feeling of the things Picasso was looking at. the world is revealed in its majesty(壮观)," he wrote.

"I'm going to fail!" My best friend cried. She and I had this conversation almost every day while we were in high school.
    The truth was that my friend never failed in any subjects. I just think that she can't accept failures because she lives her life as a perfectionist. What she fails to understand is that a lot of good can come from failures.
    For example, failure can help build relationships. Once I was cooking dinner for a friend, I was tired, and several dishes I tried to make turned out bad. I grew more and more upset until my friend told me that I shouldn't worry. She cared more about our friendship than the dishes. That day, I learned that failure doesn't always make people dislike you. In fact, after she said those words to me, I grew closer to her.
    Failure can make success evermore exciting. Every few years, there would be an important test in the PE class at our school. Students had to run a mile within eight minutes. I was never good at running, so I failed every time until the third year at school. Then I began working out regularly, and yet still failed that year. A few days later, however, the teacher gave me and some other students another chance to run and I got a pass finally! You can't imagine how excitedly I was after that. I felt the memory of the success was as sweet as honey, because I had to overcome failure to reach it.
    Now it's clear to see that failure can teach us good lessons. It's not an end, but it can be a beginning
