Before I studied psychology, I used to think that people would laugh when funny things occurred. While I was right about that, I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke. When someone laughs at a joke, there will usually bemore than one reason that makes him laugh—and the more reasons there are, the more powerful the joke will be.

    I was attending a stand-up comedy show in Egypt, and when the man started to make fun of pedestrians crossing streets, everyone laughed their hearts out. The main reason those people strongly laughed was that almost allof them felt angry towards pedestrians who crossed streets carelessly. The joke wasn't only funny, it also made the audience feel that they were right about being angry at those pedestrians. That is, people were laughing both because ofthe funny joke and because of the happiness experienced as a result of the psychological support they got.

    The better a joke makes a person feel, and the more it includes other psychological factors, the more the person will like it. For example, if you envy one of your friends, and someone tells a joke that is funny and, at the same time, makes your friend seem stupid, then you will probably laugh atit louder than if you weren't jealous of him.

    In short, we don't laugh only when we hear something funny; we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage making fun of anyone or belittling someone to make someone else laugh. All Iwant to explain is that if your joke supports a person's emotions, he will certainly like it a lot.

    Several times my daughter had telephoned to say, “Mum, you must come and see the daffodils(水仙花)before they are over.” I wanted to go, but it was a two-hour drive from Lake Arrowhead. "I will go next Tuesday," I promised, a little unwillingly, on her third call.

    The next Tuesday dawned cold and rainy. Still, I had promised, and so I drove there. When I finally walked into Carolyn's house and hugged and greeted my grandchildren, I said, "Forget the daffodils, Carolyn! The road is invisible (看不见的) in the cloud and fog, and there is nothing in the world except you and these children that I want to see!"

    My daughter smiled calmly and said, "We drive in this weather all the time, Mum. You will never forgive yourself if you miss this experience."

    After about twenty minutes, we turned onto a small road and I saw a small church. On the far side of the church, I saw a hand-lettered sign that read "Daffodil Garden."

    We got out of the car and each took a child's hand, and I followed Carolyn down the path. Then, we turned a corner of the path, and I looked up amazed. Before me lay the most beautiful sight. Flows of flowers of different colors seemed poured down the peak and slopes. There were five acres of flowers! A sea of daffodil! It was like a fairyland all beyond description.

    "But who has done this?" I asked Carolyn. "It's just one woman." Carolyn answered. "That's her home." Carolyn pointed to a well-kept A-frame house that looked small and modest in the midst of all that glory. We walked up to the house. On the patio (露台), we saw a poster." Answers to the Questions I Know You Are Asking" was the headline.

    The first answer was a simple one. "50,000 bulbs (鳞茎)" it read. The second answer was, "One at a time, by one woman." The third answer was, "Began in 1958."

    I thought of this woman whom I had never met, who, more than fifty years before, had begun one bulb at a time to bring the beauty and joy to the mountain top. Just planting one bulb at a time, year after year, had changed the world where she lived and created something of magnificence, beauty, and inspiration.

    When we multiply tiny pieces of time with small amounts of daily effort, we too can accomplish great things. Everyone can do something to change the world.

    Augusto Esquivel is a sculptor who, in his own words, is “crazy with comparisons of reality and potential and the balance between them.” Perhaps the best example of what he's talking about are his most famous creations: the suspended(悬挂的) button sculptures.

Made entirely from buttons hanging on various lengths of string, Esquivel's sculptures are made to look like common objects: a piano, a gumball machine, and even a toilet. If it wasn't for the clear string hanging above, these objects, these sculptures, would look solid, yet you can put your hands right through them. The process starts with him deciding on a subject and setting the acrylic （丙烯酸树脂）from where the buttons are being suspended. He buys buttons of different shapes and sizes, paints them with spray paint, and carefully hangs them. After that, it's a manner of hanging each individual button, which takes a lot of time. For his piano, for example, he individually hung over 60 pounds worth of tiny buttons.

Esquivel's sculptures, while mostly housed inside art galleries, perfectly capture one of the main principles of street art: something that is eye-catching and something that invites interaction. Often the best sculptures outside the art galleries aren't the ones behind guards and fencing, but the ones people can go right up to and touch. In Vancouver, a series of laughing old men are attracting people for pictures and to just generally hang around, but the people who simply walk by and see the sculptures almost always leave with a smile on their face. That's good street art: it draws the viewer in rather than relying on a gallery to draw in an audience and point them to certain pieces.

Esquivel's art is not only a presentation of talent, something that mentions larger philosophical questions, like the ones he stated above, but also just the right combination of interesting idea and painstaking work. One can look at his work in a critical way, or simply appreciate his idea and execution(艺术品的制作).

    With the development of our society, cell phones have become a common part in our lives. Have you ever run into a careless cell phone user on the street? Maybe they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new "species" of human has kept rising, they have been given a new name—phubbers (低头族).

    Recently a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes a selfie (自拍) in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events finally leads to the destruction(毁灭) of the world.

    Although the ending of the film sounds unrealistic, the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. "Always bending your head to check your cell phone could damage your neck," Guangming Daily quoted doctors' words. "The neck is like a rope that breaks after long-term stretching." Also, staring at cell phones for a long time will damage your eyesight gradually, according to the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. When getting together with family or friends, many people prefer to play their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

    It can also cost your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

    It had been a long winter. Bitter cold, snowy days had hit us again and again. On the warmer days there had been little sunshine, but only cold, icy rain. The sun had become such a rare sight that I had to look at a picture of it on my wall calendar from time to time to remember what it looked like. The grass had remained brown and dormant（潜伏的）in the grassland. My own backyard had turned into a muddy mess that tried to steal the shoes right off my feet as I walked on it. My heart ached and longed for spring, and my own good cheer had trouble rising up against the continuous, cold, gray days.

    The rain poured down on me as I walked my dogs, holding their leashes in my icy fingers. I looked up at the sky hoping to see the sun smiling down with its warm, golden face. But it was no use. It was then, however, that I saw it. It wasn't the smiling face of the sun in the sky but a little, yellow face peeking（微露出） through the mud. It was a tiny flower, and it filled my heart with hope and joy. I smiled and thanked God for this little sign that winter would soon be over and that spring would arrive. I felt my good cheer rising up at last and I promised God that I would share it with everyone I could.

    One day that tiny flower's seeds will fill the grassland with little, yellow faces smiling up from the ground. Its work will make this world a better and more beautiful place. May we all do the same. May we all shine our light and share our love even on the coldest and grayest days. May we all help to share a bit of spring in winter. May we all work to make this world better and brighter even when it is at its darkest.

    When I was a boy there were no smart phones. Computers were something you saw on STAR TREK(星际航行), and our television only got one channel clearly. Still, I was never bored. The fields, hills, and woodlands around my house were the nature ready-made playgrounds.

    I can remember once hiking to a nearby lake and slowly walking around it. At the backside of it I was amazed to find an old, one-lane, dirt road that I had never seen before. I immediately set out to travel it. It was full of holes and muddy tracks and deep woods bordered it on both sides, but exploring it still seemed like a fine adventure.

    I walked on and on for what seemed like hours. I was sure my guardian angel was whispering in my ear to turn around and head back home but I was stubborn and even a bit stupid, so I walked on.

    The dirt road give way to a rock one and then a paved one, yet there was still neither a car nor a house in sight. My legs were getting tired. I noticed that the sun was starting to go down and I grew scared. I didn't want to end up trapped on this road in the dark of night, but I was sure it would be dark before I could make my way back to the lake again.

    I was almost in tears when I turned one last curve(弯曲处) and saw something in the distance. It was a house that I recognized. My heart leapt up! I jumped up and down and laughed out loud. I knew the way home! It was still over a mile away but my legs felt like feathers and I hurried back to my house in no time. I walked in with a big smile on my face just in time for dinner.

    I remembered this recently when I saw a sign that said, “All roads lead Home.” This is true. In this life all roads no matter what their twists(弯曲) and turns are can lead us home again. They can lead us to our homes here on Earth. They can lead us to our homes in our heart, if we can insist.
