My grandfather came from Hungary and was the only one in his family who settled down in the United States. The rest of his family remained in Europe. When World War I broke out, he seemed to have become another man, downhearted. Such obvious change was not born out of concern for his welfare, but out of fear: if his only son, my uncle, had to go to war, it would be cousin fighting against cousin.

    One day in 1918, my Uncle Milton received his draft notice. My grandparents were very upset. But my mother, at the age of 10, felt on top of the world about her soldier brother going off of war. Realizing how he was regarded by his little sister and all of her friends, my uncle bought them all service pins, which meant that they had a loved one in the service. All the little girls were delighted.

    The moment came when my uncle and the other soldiers, without any training but all in uniforms, boarded the train. “The band played and the crowd cheered. Although no one noticed, I'm sure my grandmother had a tear in her eye for the only son. The train slowly pulled out, but not about a thousand yards when it suddenly paused. Everyone stared in wonder as the train slowly returned to the station. There was a dead silence before the doors opened and the men started to step out. Someone shouted, “The war is over!”For a moment, nobody moved, but then the people heard someone bark orders at the soldiers. The men lined up in two lines, walked down the steps, and with the band playing, marched down the street, as returning heroes, to be welcomed home. My mother said it was a great day, but she was just a little disappointed that it didn't last a tiny bit longer.

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple — eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

    The reason is thought to be so-called similarity attraction theory — where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

    In a test, participants were told to watch TV — where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble (咬), while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too.

    The researchers added, “Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions (交易) from the start.”

    Harley Street psychologist Dr. Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, “This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful.”

    Americans gave nearly $300 billion away last year. Do you know the reason? Beyond the noble goals of helping others, it is that giving will make them happier.

    It is a fact that givers are happier people than non-givers. According to the Social Capital Community Benchmark Survey, a survey of 30,000 American households, people who give money to charity are 43% more likely than non-givers to say they are "very happy" about their lives. Similarly, volunteers are 42% more likely to be very happy then non-volunteers.

    The happiness difference between givers and non-givers is not due to differences in their personal characteristics, such as income or religion. Imagine two people who are identical in terms of income and faith, as well as age, education, politics, sex, and family circumstances, but one donates money and volunteers, while the other does not. The giver will be, on average, over 40 percentage points more likely to be very happy than the non-givers.

    A number of studies have researched exactly why charity leads to happiness. The surprising conclusion is that giving affects our brain chemistry. For example, people who give often report feelings of euphoria, which psychologists have referred to as the "Helper's High". They believe that charitable activity produces a very mild version of the sensations people get from drugs like morphine and heroin.

    Of course, not only does giving increase our happiness, but also our happiness increases the possibility that we will give. Everyone prefers to give more when they are happy. Researchers have investigated this by conducting experiments in which people are asked about their happiness before and after they participate in a charitable activity, such as volunteering to help children or serving meals to the poor. The result is clear that giving has a strong, positive causal impact on our happiness, so does happiness on giving

    The traditional tent cities at festivals such as Glastonbury may never be the same again. In a victory of green business that is certain to appeal to environmentally-aware music-lovers, a design student is to receive financial support to produce eco-friendly tents made of cardboard that can be recycled after the bands and the crowds have gone home.

    Major festivals such as Glastonbury throw away some 10,000 abandoned tents at the end of events each year. For his final year project at the University of the West of England, James Dunlop came up with a material that can be recycled. And to cope with the British summer, the cardboard has been made waterproof.

    Taking inspiration from a Japanese architect, who has used cardboard to make big buildings including churches, Mr. Dunlop used cardboard material for his tents, which he called Myhabs.

    The design won an award at the annual New Designers Exhibition after Mr. Dunlop graduated from his product design degree and he decided to try to turn it into a business.

    To raise money for the idea, he toured the City's private companies which fund new businesses and found a supporter in the finance group Mint. He introduced his idea to four of Mint's directors and won their support. Mint has committed around ￡500,000 to MyHab and taken a share of 30 per cent in Mr. Dunlop's business. The first Myhabs should be tested at festivals this summer, before being marketed fully next year.

    Mr. Dunlop said that the design, which accommodates two people, could have other uses, such as for disaster relief and housing for the London Olympics.

    For music events, the cardboard houses will be ordered online and put up at the sites by the Myhab team before the festival-goers arrive and removed by the company afterwards. They can be personalized and the company will offer reductions on the expense if people agree to sell exterior(外部的) advertising space.

    The biggest festivals attract tens of thousands of participants, with Glastonhury having some 150,000 each year. Altogether there are around 100 annual music festivals where people camp in the UK. The events are becoming increasingly environmentally conscious.

    I'd done it before, and so I had no reason to believe that this time would be any different. I was sure that when I returned home from my mission trip. As always, I'd bring back nothing more some mud on my boots. A hole or two in my jeans and, of course, a lot of great memories.

    The summer before my high school graduation, I went to West Virginia with others as volunteers to repair the homes of those in need. Arriving at our destination, my group was assigned the task of rebuilding sections of a home that had been damaged by fire. No sooner had we parked on the home's dirt driveway than we saw an excited little girl, no more than six years old, standing in the doorway of the family's temporary home. Shoeless and wearing dirty clothes and the biggest smile I'd ever seen, she yelled, "Ma, Ma, they really came!" I didn't know it then, but her name was Dakota, and four more days would pass before she'd say another word near me.

    Behind Dakota was a woman in a wheelchair — her grandmother, we'd soon learn. I also discovered that my job that week would be to help change a fire-damaged dining room into a bedroom for this little girl. Grabbing our tools, we went to work. Over the following days, I noticed Dakota peeking at us every now and then as we worked. A few times, I tried talking with her, but she remained shy and distant, always flying around us like a tiny butterfly but keeping to herself.

    By our fifth and final day, however, this was about to change.

    Before I went to work on her home on that last morning, I spoke for a moment or two with the grandmother. I was especially pleased when she told me how much Dakota loved her new room — so much, in fact, that she'd begged to sleep in it the previous night, even though it wasn't quite ready. As we talked, I noticed something I hadn't seen before — Dakota was hiding behind her grandmother.

    Cautiously, she stepped into view, and I could see that just like her clothes, her face was still dirty. But no amount of soil could hide those bright blue eyes and big smile. She was simply adorable. I wanted so much to hug her, but respecting her shyness, I kept my distance.

    Slowly, she began walking toward me. It wasn't until she was just inches away that I noticed the folded piece of paper in her tiny hand. Silently, she reached up and handed it to me. Once unfolded, I looked at the drawing she'd made with her broken crayons on the back of an old coloring book cover. It was of two girls — one much taller than the other — and they were holding hands. She told me it was supposed to be me and her, and on the bottom of the paper were three little words that instantly broke my heart. Now almost in tears, I couldn't control myself anymore — I bent down and hugged her. She hugged me, too. And for the longest time, neither of us could let go.

    By early afternoon, we finished Dakota's bedroom, and so I gladly used the rare free time to get to know my newest friend. Sitting under a tree away from the others, we shared a few apples while she told me about her life. As I listened to her stories about the struggles she and her family went through daily, I began to realize how boring various aspects of my own life were.

    I left for home early the next morning. I was returning with muddy boots and holes in my Jeans. But because of Dakota, I brought back something else, too-a greater appreciation for all or the blessings of my life. I'll never forget that barefoot little butterfly with the big smile and dirty face. I pray that she'll never forget me either.

    A Christmas Carol was written by Charles Dickens. The first 6,000 copies of the book were sold out in a week. And the book has inspired many plays and movies. The first play was put on in 1844. The first two movies were silent films made in 1901 and 1908. Since then, the story has been remade more than 60 times for television and cinema. What makes such a tale so attractive? Audiences have always loved a good plot, a villain(反面人物)who harms other people or breaks the law, and the ending of right over wrong. The book offers all three.

    The book tells the story of a man named Ebenezer Scrooge. He is mean and cruel(残忍的)to his clerk and turns away his only living relative. One night, Scrooge is visited by three spirits. The first shows scenes from Scrooge's youth that led to this present state. The second takes him to the homes of his clerk and his nephew. Here Scrooge sees that people can be happy without lots of money. The spirit also shows him the desperate poor people of London. The third spirit shows Scrooge will die alone, and no one will care if he continues to live as he has. At last the message is understood, and Scrooge repents. He becomes generous and caring to all around him, especially to his clerk's sick son, Tiny Tim.

    Every year, thousands of people watch A Christmas Carol. Why? They may be touched by its lessons on the true meanings of wealth and happiness. They may enjoy the special effects and feelings or watching every year may be just a habit. Viewers never seem to grow tired of the old miser(守财奴), Scrooge, and his dramatic message of hope and change.
