No one can deny that buttons are an important device. Whenever we see a button, we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the “on/off” button on the TV. But some buttons are actually fake, like the “close” button on a lift.

    Many people are in the habit of pressing the “close” button because they don't have the patience to wait for the lift doors to shut. But lifts' “close” buttons are a complete scam (骗局), at least in the US － the doors will not close any faster no matter how hard you press.

    It started in the 1990s when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.

    But to normal lift riders, the buttons aren't completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control.

     “Perceived (能够感知的) control is very important. It reduces stress and increases well-being,” Ellen J. Langer, a psychology professor, said, “ having a lack of control is associated with depression.”

    Experts have revealed that a lot of buttons that don't do anything exist in our lives for this same purpose. For example, many offices in the US have fake thermostats (温度调节器) because people tend to feel better when they think they can control the temperature in their workspace.

    But psychologists found it interesting that even when people are aware of these little “white lies”, they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

     “That habit is here to stay,” John Kounios, a psychology professor, said. “Even though I have real doubts about the traffic light buttons, I always press them. After all, I've got nothing else to do while waiting. So why not press the button in the hope that this one will work?”

    Body language is one of the most powerful means of communication, often even more powerful than spoken language. It is said that our body movements communicate about 50 percent of what we really mean while words only express 7 percent. So, while your mouth is closed, your body is just saying.

    Arms. How you hold your arms shows how open and receptive you are to people you meet. If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of taking on whatever comes your way. Outgoing people generally use their arms with big movements, while quieter people keep them close to their bodies. If someone upsets you, just cross your arms to show you're unhappy!

    Head. When you want to appear confident, keep your head level. If you are a monitor in class, you can also take on this position when you want your words to be taken seriously. However, to be friendly in listening or speaking, you must move your head a little.

    Legs. Your legs tend to move around a lot more than normal when you are nervous or telling lies. If you are at interviews, try to keep them still!

    Posture (姿势). A good posture makes you feel better about yourself. If you are feeling down, you normally don't sit straight, with your shoulders inwards. This makes breathing more difficult, which can make you feel nervous or uncomfortable.

    Mouth. When you are thinking, you often purse(噘嘴) your lips. You might also use this position to hold back an angry comment you don't wish to show. However, it will probably still be noticed, and people will know you're not pleased.

    Face. When you lie, you might put on a false face. But that expression would crack briefly, allowing displays of true emotions such as happiness, sadness, disgust (厌恶) and fear to come through.

    Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

    Sometimes, the word “green” means young, fresh and growing. For example, a greenhorn is someone who has no experience. In the 15th century, a greenhorn was a young cow or an ox whose horns(角)had not yet developed. A century later, a greenhorn was a soldier who had no experience in war. By the 18th century, a greenhorn had the meaning it has today—a person who is new in a job.

    Someone who is good at growing plants is said to have a green thumb(大拇指). The expression comes from the early 20th century. A person with a green thumb can make plants grow quickly and well.

    Green is also the color used to describe the powerful feeling , jealousy(嫉妒). The green-eyed monster （怪物）is not a dangerous animal from outer space. It is an expression used about 400 years ago by the British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling when someone has something he wants. For example, a young man may suffer from the green-eyed monster if you get a pay rise and he does not.

    In most places in the world, a green light means to move ahead. In everyday speech, a green light means agree to continue with a project.

    From childhood, Moira loved to write. Throughout school she enjoyed writing, but pursuing it professionally was never a possibility. Her father was a doctor, her mother a nurse. “Medicine was a fairly safe choice,” Moira says, “and writing was a career where it wasn't a certainty that you'd have high income.”

    She became a doctor but still wanted to write something. However, being a doctor was so demanding that she didn't take up writing until her thirties. She produced a novel—a fictionalized version of her travel in China after university. She got excellent reviews. Moira sent it off to as many agents as she could find, and found one who wanted to represent her. Suddenly, it seemed she was on her way as an author.

    “I had one lengthy phone call with the agent where we went through all possible areas that she thought needed polishing. I worked on those and sent it back to her but didn't hear anything.” It wasn't long before Moira found another agent who was interested if she was willing to rewrite it from the first person to the third person. She did the hard work and sent it off again. “I got back a really brief letter: 'Thank you, I'm no longer interested.' It was really disappointing.”

    A decade went by, and Moira found herself eager to write again, this time purely for her own enjoyment. She set herself the challenge of creating a thriller and chose Western Australia as her setting.

    As she was writing just for herself, something surprising began to happen. “The characters took on a life of their own; they started doing things I hadn't thought about. It just flew.” One day, an agent called from Australia. Three weeks later, Moira had a publication deal. Her novel, Cicada, was published in March.

    “Even if it hadn't been published I still gained so much from the process,” says Moira.

    The pupils of Grangetown High have been busy getting to know their newest and tallest classmate — a 7-meter-tall giraffe outside their school.

    The giraffe is a huge sculpture (雕像). The school's headmaster noticed it in an artist's garden as he drove past one day, and thought it would be perfect for his school. “I knew everyone would love it," he said, "because our basketball team is known as the Grangetown Giraffes, and they wear giraffes on their shirts. So I asked them to write to the artist, asking how much it would cost to buy the giraffe. He was very kind and got it ready to deliver (递送) in six weeks — all for nothing! It was expected to arrive one Sunday morning, so that the pupils would see it when they got to school on Monday — at that time they had no idea that we were getting it."

    The artist, Tom Bennett was a university professor of chemistry before he retired in 2012 and only took up metalwork a couple of years ago. "I've always drawn pictures," he said. I can even remember doing it on my first day at school — I drew a horse. I wanted it to be the best horse picture ever, but I don't think I succeeded."Tom's first metalwork was a bicycle on which he and his wife could go cycling together, “It was the most uncomfortable bike ever created," he said, "so I gave up making bicycles and went into sculpture instead."

    Meanwhile the pupils at Grangetown High are very happy with their new classmate. "We're going to hold a competition to give it a proper name," said one girl. "Everyone likes the expression on its face, so perhaps that will give us some ideas."

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.
