In modern society there is a great deal of argument about competition. Some value it highly, believing that it is responsible for social progress and prosperity; others say that competition is bad because it sets one person against another and because it leads to unfriendly relationship between people.

    I have taught many children who held the belief that their self-worth relied on how well they performed at tennis and other skills. For them, playing well and winning are often life-and-death affairs. In their single-minded pursuit of success, the development of many other human qualities is sadly forgotten.

    However, while some seem to be lost in the desire to succeed, others take an opposite attitude. In a culture which values only the winner and pays no attention to the ordinary players, they strongly blame competition. Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society. Teaching these young people, I often observe in them a desire to fail. They seem to seek failure by not trying to win or achieve success. By not trying, they always have an excuse: “I may have lost, but it doesn't matter because I really didn't try.” What is not usually admitted by themselves is the belief that if they had really tried and lost, that would mean a lot. Such a loss would be a measure of their worth. Clearly, this belief is the same as that of the true competitors who try to prove themselves. Both are based on the mistaken belief that one's self-respect relies on how well one performs in comparison with others. Both are afraid of not being valued. Only as this basic and often troublesome fear begins to dissolve (缓解) can we discover a new meaning in competition.

    When an earthquake hit a small town，many houses fell down.After the earthquake，all the newspapers reported many stories about some of the families who were in trouble.

    One Sunday，when I was reading a newspaper，a special picture touched me.It gave the clothing sizes of each family member.I thought that this would be a good chance to teach my children to help those who were less lucky than themselves.I said to my seven years old twins，Brad and Brett，and three years old Meghan，"We have so much，and these poor people now have nothing.We'll share what we have with them."

    I filled a box with foods and clothes.While I was doing this, I encouraged the boys to choose their toys and donate some of their less favourite things.Meghan watched quietly as the boys took out their old toys and games and put them together.Then she walked away.A few minutes later she came back with Lucy，her much loved doll.She put the doll on top of the other toys. "Oh, dear," I said. "You don't have to give Lucy.You love her so much."Meghan said，"Lucy makes me happy，Mommy.Maybe she'll make another little girl happy, too."

    I looked at Meghan for a long moment.She taught me a lesson.It's easy to give something that we don't want any more，but hard to give what we cherish(珍爱)，isn't it?

    It is commonly believed that the earliest Chinese paper-cuts appeared during the sixth century. Some scholars believe it was even earlier. Legend has it that during the Western Han Dynasty(206BC-AD24), Emperor Wudi was very sad after one of his favorite concubines, Madame Li, died. A Taoist priest, Li Shaoweng, cut a piece of hemp paper in the shape of Madame Li. When evening fell, the emperor's servants lit candles in his bedroom; the reflection of that paper-cut on the wall made the emperor think about his beloved concubine.

    The Yuxian paper-cut is different from most paper-cuts produced in other regions of China. Paper-cuts from other regions are mostly cut with scissors or knives from single-colored paper, such as red or black paper.

    There are four major procedures to making the Yuxian paper-cut: First, sketch the pattern on the draft paper; second, fasten the draft to the paper to be cut; third, use a knife to carve out the pattern; and fourth, dye (染色) the paper-cut with various colors.

    Precise cutting skills are needed to make a piece of the Yuxian paper-cut, which highlights the craft maker's artistic taste and dyeing skills. That explains the following saying: "The successful making of a Yuxian paper-cut is 30 percent dependent on the maker's cutting skills, and 70 percent on the maker's dyeing skills."

    The traditional Yuxian paper-cut highlights two themes: flowers and characters in Chinese operas. The paper-cut is particularly known for its vivid description of characters in various traditional Chinese operas. In October 2009, the art of Yuxian's paper-cut was added to the list of Intangible Cultural Heritage (非物质文化遗产) established by UNESCO (United Nations Educational, Scientific, and Cultural Organization).

    Both honeybees and ants are social insects that live in groups called colonies. They survive by means of their collective intelligence. Their decision-making power is distributed throughout the group; that is, no one ant or bee makes decisions for the group. Instead, they work together. As Deborah M. Gordon, a biologist at Stanford University, says," Ants aren't smart. Ant colonies are."

    The same is true for bee colonies. Although bees and ants are quite different physically, they have a lot in common in terms of their social behavior. Specifically, honeybees and ants have similar roles within the colony, both have communication systems, and both have the capacity for learning.

    Ants communicate by using chemicals called pheromones, which can alert others to danger or to a food source. For example, when worker ants find a promising source, they let the rest of the colony know how to find it by leaving a trail of pheromones on the way back to the colony. The other ants pick up the message using their sense of smell. Bees, on the other hand, use movement to communicate with each other. Worker bees send messages to each other by means of a "dance". Different speeds and movements send different messages. For example, when worker bees called scouts go out to find a new home for the colony, they return and do a dance for the other worker bees that indicates the location of the new home and how suitable it is. The faster the scouts dance, the better the new location is.

    Honeybees and ants are both capable of learning. One Chinese study found that bees can be trained to learn and remember a route to a food source. The researchers also found that bees can be taught to recognize hidden objects and use the concepts of "sameness" and" difference" to accomplish certain tasks. Ants take this one step further. Recent American research has shown that ants not only have the ability to learn, but also can teach their foraging skills to other younger ants.

They observed that older ants accompany young ants in search of food and teach them the route and how to avoid obstacles.

    As we can see, the social behavior of honeybees and ants is quite similar. Both coordinate complex actions and accomplish crucial survival tasks by cooperating in groups consisting of many individuals. Unintelligent as they may be as individuals, as groups they often show amazing brilliance as they go about their everyday activities.

    "Make way, good people, make way, in the King's name! "cried he. "Open a text; and, I promise you, Mistress Prynne shall be set where man, woman, and child, may have a fair sight of her brave clothing, from this time till an hour past noon. A blessing on the moral Colony of the Massachusetts, where immorality is dragged out into the sunshine! Come along, Madam Hester, and show your scarlet （鲜红色的；罪孽深重的）letter in the market-place!

    A lane was at once opened through the crowd. Led by the beadle （狱吏），and attended by an irregular procession of serious-looking men and unkind-looking women, Hester Prynne set forth towards the place appointed for her punishment. A crowd of eager and curious schoolboys, understanding little of the matter in hand, except that it gave them a half-holiday, ran before her progress, turning their heads continually to stare into her face, and at the winking baby in her arms, and at the shameful letter on her breast.

    It was no great distance, in those days, from the prison-door to the market-place. Measured by the prisoner's experience, however, it might be considered to be a rather long journey; for, though her manner was proud, she perhaps underwent an extreme pain from every footstep of those who thronged to see her, as if her heart had been thrown into the street for them all to step upon. In our nature, however, there is a condition that the sufferer should never know the intensity of what he endures by its present suffering, but chiefly by the pain that rankles （使痛心）after it. With almost a calm manner, therefore, Hester Prynne passed through this portion of her suffering, and came to a sort of scaffold （刑台），at the western end of the market-place. It stood nearly beneath the eaves of Boston's earliest church, and appeared to be a fixture there.

    TRAIL SAFE! is a unique safety training program designed specifically for National Park Service (NPS) Trail Volunteers, but is useful to everyone!
