Idema, a Dutch Sinologist（汉学家）, has served as the director of the Chinese Languages and Cultures Department at Leiden University of the Netherlands and was also director of Harvard's Fairbank Center for East Asian Research.He has studied ancient Chinese plays, novels and literature, and has authored or translated a number of influential books published in English and other languages.

    The 70-year-old Dutch Sinologist recalled his half-century-long romance with Chinese culture during a recent visit to Beijing.As a child,the vivid descriptions of China in Nobel and Pulitzer Prize-winner Pearl S.Buck's books sparked Idema's interest in the country.He later read classic Chinese literature and spent whole days pouring through works at the National Library of China.

    While many other experts on China focused on the country's economic transformation, Idema continued to study traditional Chinese literature."There were scholars studying law, religion and society, but not traditional Chinese literature,which was my personal interest," Idema explains.

    Finding reference books for his research,especially regional publications,used to be a huge challenge,and Idema used to spend a lot of time collecting books and other materials during visits to China.Now it is much more convenient with the Internet.

    Idema usually chooses less-known subjects for his research and tries to get firsthand materials.In recent years, he has devoted himself to translating Chinese folk tales and writing about Chinese folk society and folk culture.

    "Traditional Chinese culture is a passion.I have been studying it for 50 years and will continue to do so,"says the retired professor.

    America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

    Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

    Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don't show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.

    For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

    Rodney Smith, Jr. started mowing the lawns (割草坪) in Huntsville, Alabama last fall. He used his time between classes at Alabama A&M to reach a goal of mowing 100 yards before winter. Smith has been cutting grass for free to help single moms, the elderly, and the disabled, while teaching the local youth the values that can turn boys into men. “I'm doing something positive. I want boys to follow me and be better than me,” he wrote on his Facebook page.

    Rodney is from Bermuda. He says people there help each other and are always friendly. “That's what drives me to help people.”

    In May this year, he was getting ready to launch his mowing service for the summer when he heard about a 93-year-old woman trying to cut grass by herself. Smith and a friend showed up to do the job for her.

    In November, a local TV station gave him $300, calling it a special gift for his good work. After he received the money, he used it to create the non-profit(非盈利的) service group, Raising Men Lawn Care Service. He also started a page to collect money to buy lawn equipment and other things—including T-shirts with special logos.

    After I read about Rodney's story, I told my friends about him. We also planned to mow lawns for single moms, the elderly and disabled in our neighborhood. And I hope more and more young people will join Rodney's service group—Raising Men Lawn Care Service.

    David Beckham was born in 1975 in London, at a place called Leytonstone. When he was a young boy, his greatest passion was in football. He played it whenever he had the chance. Sometimes he would go and watch a game with his friends. When David Beckham was 12 years old, he won the Bobby Charlton Soccer Skills award. This was an important step forward for this young boy, and it led him to go for a visit to a football training camp in Spain. As a boy he played for schools of Essex and also for his county team.

    In 1991, he became a trainee with Manchester United. This meant that he could practice football as much as he wanted to and play for the highly successful Manchester United Youth Cup team and Under-21 team. In April, 1995 he played his first football league game against Leeds Untied. During 1995 and 1996, David became a regular member of the team and Manchester United won in both football seasons, with David scoring many goals.

    His goals made him a household name. In the first game of the 1996-1997 season, he scored a surprising goal from beyond the halfway line; seeing the goalkeeper a little way out of his goal, Beckham became famous overnight. He continued to score astonishing goals, especially from free-kicks. The speed of one of his shots was timed at 157 kph. He also had the ability to make the ball go from left to right, or right to left, whenever he chose. Goalkeepers were never sure where the ball was going, and it regularly ended up in the goal.

    Prosocial behaviors are those intended to help other people. Behaviors that can be described as prosocial include feeling empathy(同感) and concern for others and behaving in ways to help or benefit other people.

    Prosocial behavior has long posed a challenge to social scientists seeking to understand why people engage in helping behaviors that are beneficial to others, but costly to the individual performing the action. Why would people do something that benefits someone else but offers no immediate benefit to the doer?

    Psychologists suggest that there are a number of reasons why people engage in prosocial behavior. In many cases, such behaviors are fostered during childhood and adolescence as adults encourage children to share, act kindly, and help others. Prosocial behaviors are often seen as being compelled by a number of factors including egoistic reasons (doing things to improve one's self­image), reciprocal benefits (doing something nice for someone so that they may one day return the favor), and more altruistic reasons (performing actions purely out of empathy for another individual).

    Characteristics of the situation can also have a powerful impact on whether or not people engage in prosocial actions. The bystander effect is one of the most notable examples of how the situation can impact helping behaviors. The bystander effect refers to the tendency for people to become less likely to assist a person in distress when there are a number of other people also present. For example, if you drop your purse and several items fall out on the ground, the likelihood that someone will stop and help you decreases if there are many other people present. This same sort of thing can happen in cases where someone is in serious danger, such as when someone is involved in a car accident. In some cases, witnesses might assume that since there are so many other present, someone else will have surely already called for help.

    Why do people help in some situations but not in others? Experts have discovered a number of different situational variables that contribute to (and sometimes interfere with) prosocial behaviors. First, the more people that are present decreases the amount of personal responsibility people feel in a situation. People also tend to look to others for how to respond in such situations, particularly if the event contains some level of ambiguity. Fear of being judged by other members of the group also plays a role. People sometimes fear leaping to assistance, only to discover that their help was unwanted or unwarranted. In order to avoid being judged by other bystanders, people simply take no action.

    Experts have suggested that some key things must happen in order for a person to take action.

    In the western Los Angeles sits the famous city of Hollywood, known as the global center of movie studios and film stars.

    The Selig Film Manufacturing Company was the first major film company to come to Hollywood, shooting its first film entitled The Heart of A Race Tout in 1908. The next year the film company built the first permanent film studio.

    Although electric lights existed at that time, none were powerful enough to adequately expose film. The best source of illumination for movie production was nature sunlight. Besides the sunny weather, film producers were also drawn to Hollywood because of its open spaces and wide variety of natural scenery.

    Another reason was the distance of Southern California from New Jersey, which made it more difficult for Thomas Edison to enforce his film patents. At that time, Edison owned almost all the patents relevant to film production. As a result, in the East, movie producers acting independently out of Edison's Motion Picture Patents Company were often accused by Edison. But in Los Angeles, things were different. If he sent his men to California, word would usually reach Los Angeles before they did and the movie makers could escape to nearby Mexico.

    In 1911, a second movie studio—Nestor Studios, was founded. At about the same time, many film production companies from New York and New Jersey started moving to sunny California because of the good weather.

    The first Academy Awards presentation ceremony took place in 1929 in the Hollywood Roosevelt Hotel. Tickets were $10 and there were 250 people attending the ceremony.

    From about 1930, five major "Hollywood" movie studios in Hollywood, Paramount, RKO, 20th Century Fox, Metro-Goldwyn-Mayer and Warner Bros, owned almost all large theatres throughout the country for the exhibition of their movies. The period between the years 1927 to 1984 was considered the "Golden Age of Hollywood".
