“Community” is not a concept that is easy to define (定义) . In this essay I will examine what turns individuals into a community, and discuss some different types. I will also look at what all communities have in common, the benefits they offer and draw conclusions about their increasing importance.

    The word “community” may make you think of traditional communities in the developing world, where large families live together. We may also imagine the neighbours as people who are happy to help out whenever it is needed. The stereotpical(老套的) view is that of a village, where people have little but can feel very rich because everyone takes responsibility for the welfare of the others.

    On the other hand, there are other types of communities: ultramodern(超现代的) ones, where the community members are unlikely to have actually met each other. These are online communities, where people blog or chat about particular issues that are important to them. They come across others on websites and may develop a relationship there with like-minded people, discussing the same topics. The view is often that these are artificial connections between people who are, in effect, still isolated(孤立的) strangers.

    In reality, the connections are real. Moreover, there are many types of communities in between these extremes: people who join clubs, who sign up with voluntary, political or other organizations, or who take part in group discussions in their local area. They may be campaigning about issues or simply getting together for companionship and support.

    Human beings are social by nature, so it should not be a surprise that we organize ourselves in groups. However, there is more going on: these groups provide something that we cannot achieve on our own. The main benefit of being part of a larger group is strength in numbers. For example, we can access and share more information, we can take part in team sports, we can complain and campaign more effectively and even if we are just having a chat, online or in person, we can feel supported in whatever we do.

    Whatever forms communities take, what defines them is the sense of identity and safety that they provide for their members: the knowledge that there are people who we have something in common with and who can be relied on when we need each other.

    Once upon a time there were two friends who lived in a palace and worked in the service of the king. One of the two boys knew a girl he liked so much that he wanted to give her a present.

    One day, when he was walking with his friend in the main palace hall, he saw a big vase filled with the most beautiful flowers. He decided to take one to give to the girl, thinking that no one would see him do so except his friend. He did the same thing the next day, and the next, and the next... until, one day, the king noticed how few flowers were left in the vase. He was so angry that he called everyone in the palace to come together in the hall.

    When they were all before the king, the boy thought he should say it was he who had taken the flowers. However, his friend told him to be quiet, because the king would be terribly angry with him. The boy was filled with fear, but when the king came near, he decided to confess.

    As soon as the boy said that he had done it, the king went red with anger, but on hearing what the boy had done with the flowers, a smile appeared on the king's face, and he said, “I couldn't have thought of a better use for my flowers.”

    And from that day, the boy and the king became great friends. They went to the vase and took two of those wonderful flowers, one for the girl, and the other for the queen.

    After retirement, Michael Kennedy could have chosen to take walks around his seaside home. Instead, the former mechanical engineer engaged himself in the toughest task of his life - keeping the thundering waves of the Norfolk coast.

    The 73-year-old has spent the past 14 years building his own sea wall at Hunstanton, piling up rocks picked from the sandy beach to slow the erosion （侵蚀）of the soft limestone （石灰岩）and chalk cliffs. It's estimated that Michael has shifted 200 tons of stone in the last 14 years.

    “It's a real labour of love because I come down here whatever the weather, in spring, summer, autumn and winter,” said the divorced father of two. “It keeps me fit and I love it.”

    Mr Kennedy moved to the area after retiring from the London Underground. Nicknamed Fred Flintstone by locals, he tries to move at least 40 pounds of rocks in two-hour sessions which he finishes by 2 pm.

    Everything he collects is placed into piles at the foot of the cliffs. Larger rocks go at the bottom to provide the main line of defence and smaller ones are placed at the top. He also picks up rubbish and prides himself on having created a spotless, stone-free sandy beach for holidaymakers to enjoy.

    The work goes on six days a week. Saturdays are his day off so that the Chelsea “fanatic” can watch football and other sports. However, there are signs that he is becoming a victim of his own success, as the number of stones has dwindled significantly in recent months.

    “It's confusing, Mr Kennedy said. “Usually every year the stones just come in with the sea but this year we haven't had any.” He added, “I hope to still be doing it when I'm 100 but perhaps just four days a week instead of six.”

    Town mayor Peter Mallam said Mr Kennedy had become “quite a local legend”. “It's fascinating. Everyone knows of the old guy who collects the stones. He's done a sterling effort.”

    Visual language is a form of communication that uses visual elements (元素) as opposed to formal written language to convey meaning or an idea, Graphicacy, the ability to communicate visually, is considered as important as literacy and numeracy, the abilities to read and count. Some people are visual thinkers, using that part of the brain that is emotional and creative to process and give meaning to information. Visual communication can find expression in paintings, drawings, symbols, or simply lines and shapes arranged for a specific effect.

    Art is an example of visual language. A painting or sculpture can convey ideas or arouse specific kinds of emotional responses. It may also express ideas about historical events, abstract concepts, or simply be about the way certain shapes or forms "work" together or create a certain effect on the mind. Some researchers believe that different parts of the brain respond in unique ways to colors and shapes.

Pictograms (象形文字) and ideograms (表意文字) are types of visual language. Pictograms are pictures that are similar to what they represent. They are still used today to communicate information. Many people around the world are familiar with the pictograms indicating such things as airports, public facilities, and non-smoking areas indicated by a cigarette in a circle with a line across it. Ideograms are pictures that represent ideas and can often be understood without the aid of written language. Some scholars track modern alphabets to pictures Letters are actually ancient pictures, and words are a series of pictures. Modern alphabet letters are not only phonetic (语音的) symbols but are based on ancient religious images and symbols.

    Musivisual communication is also a part of visual language. The term refers to music created specifically to improve the visual experience of film. It corresponds to the images being seen on the screen, and the music may arouse a sense of terror, fear, or other emotions. Most movie goers understand the language of musical clues showing that something dramatic or important is about to happen.

    We often hear stories of animals rescuing people. But now someone has managed to return the favor.

    The event took place one snowy January morning Thomas Smith was walking his dog, Jack, in the park." As I was walking, I just saw Jack running onto the ice towards the ducks in the middle, and then he fell into the water and couldn't climb out, "said Smith. He realized he had no choice but to try and save his dog. "Someone else told me the lake was only one-meter deep, but it was at least twice that. I had to break my way through the 6-cm ice. Finally, I got Jack by the neck, and pulled him out. I don't think I have ever felt so cold by the time we got back to dry land. And when we got there, everyone was asking if Jack was okay no one was particularly worried, about me!"

    A neighbor, Julie Brown, saw it all happen. "The dog went onto an icy lake. All of a sudden, it started to go under. There were crowds of people around, and they were all shouting and screaming. Before I knew it, the owner Smith was in the water forcing his way through the ice. I can't begin to imagine how cold it was. Everyone was very nervous, but he was as cool as a cucumber he just crawled back out, put the dog on its lead, and went home."

    Many regard him as a hero, but Mr. Smith is quite laid-back about it. "Most dog owners are the same as me. They would do what I did without a second thought. But in the future, I'm going to make sure he's on lead near any ice ponds, Pets are members of our family. Would you do the same for them?

    In a recent series of experiments at the University of California, researchers studied toddlers' thinking about winners and losers, bullies (欺凌) and victims.

    In the first experiment, toddlers (学步儿童) watched a scene in which two puppets (木偶) had conflicting goals: One was crossing a stage from right to left, and the other from left to right. The puppets met in the middle and stopped. Eventually one puppet bowed down and moved aside, letting the other one pass by. Then researchers asked the toddlers which puppet they liked. The result: 20 out of 23 toddlers picked the higher-status puppet — the one that did not bow or move aside. It seems that individuals can gain status for being dominant (占优势的) and toddlers like winners better than losers.

    But then researchers had another question: Do toddlers like winners no matter how they win? So, researchers did another experiment very similar to the one described above. But this time, the conflict ended because one puppet knocked the other down and out of the way. Now when the toddlers were asked who they liked, the results were different: Only 4 out of 23 children liked the winner.

    These data suggest that children already love a winner by the age of 21-31 months. This does not necessarily mean that the preference is inborn: 21 months is enough time to learn a lot of things. But if a preference for winners is something we learn, we appear to learn it quite early.

    Even more interesting, the preference for winners is not absolute. Children in our study did not like a winner who knocked a competitor down. This suggests that already by the age of 21-31 months, children's liking for winners is balanced with other social concerns, including perhaps a general preference for nice or helpful people over aggressive ones.

    In a time when the news is full of stories of public figures who celebrate winning at all costs, these results give us much confidence. Humans understand dominance, but we also expect strong individuals to guide, protect and help others. This feels like good news.
