Family structure is the core of any culture. A major function of the family is to socialize new members of a culture. As children are raised in a family setting, they learn to become members of the family as well as members of the larger culture. The family provides the model for all other relationships in society. Through theobservations and modeling of the behavior of other family members, children learnabout the family and society including the values of the culture. Familystructure and their inherent relationships and obligations are a major sourceof cultural difference.

        The family is the center of most traditional Asians' lives. Many people worry about their families' welfare,reputation, and honor. Asian families are often extended, including severalgenerations related by blood or marriage living in the same home. An Asianperson's misdeeds are not blamed just on the individual but also on the family—includingthe dead ancestors.

        Traditional Chinese, among many otherAsians, respect their elders and feel a deep sense of duty toward them.Children repay their parents' sacrifices by being successful and supportingthem in old age. This is accepted as a natural part of life in China. Incontrast, taking care of aged parents is often viewed as tremendous burden inthe United States, where aging and family support are not honored highly.

        The Vietnamese family consists of peoplecurrently alive as well as the spirits of the dead and of the as-yet unborn.Any decisions or actions are done from family considerations, not individualdesires. People's behavior is judged on whether it brings shame or pride to thefamily. Vietnamese children are trained to rely on their families, to honorelderly people, and to fear foreigners. Many Vietnamese think that theiractions in this life will influence their status in the next life.

        Fathers in traditional Japanese familiesare typically strict and distant. Japanese college students in one study saidthey would tell their fathers just about as much as they would tell a totalstranger. The emotional and communication barrier between children and fathersin Japan appears very strong after children have reached a certain age.

        Although there has been much talk about"family values" in the United States, the family is not a usual frameof reference for decisions in U.S. mainstream culture. Family connections arenot so important to most people. Dropping the names of wealthy or famous peoplethe family knows is done in the United States, but it is not viewed positively.More important is a person's own individual "track record" ofpersonal achievement.

       Thus, many cultural differences exist infamily structures and values. In some cultures, the family is the center oflife and the main frame of reference for decisions. In other cultures, theindividuals, not the family, is primary. In some cultures, the family'sreputation and honor depend on each person's actions; in other cultures,individuals can act without permanently affecting the family life. Somecultures value old people, while other cultures look down on them.

    An interesting study posted on Facebook recently shows how men and women develop new interests as they mature(成熟).

    While women tend to take exercise seriously from the age of 34, men will wait until their 45th birthdays before working hard to get in shape. The average woman spends more time talking about sports, politics, career and money as she gets older.

Women's interest in books reaches its peak(顶峰) at the age of 22, while that of men does so when they are in their 50s.

    Men start to change their focus from the workplace to other things after age 30, while women do not do so until eight years later. Both, however, care most about fashion at age 16.

    The research used anonymous(匿名的) data donated by thousands of Facebook users, recording the statuses, 'likes' and 'interests' they had posted on their profiles.

It found the average woman talks about television most at 44, while men peak much younger, at age 31.

    Men are also most likely to see a film in a cinema at age 31, while women go out to see films most when they are only 19.

    Men are most interested in travel at 29, women at 27, while women talk most about food and drink at 35, and men at 38.

    And if you are middle aged, a safe topic for any audience is the weather, which is a key interest for many as they approach 60.

    Stephen Wolfram, the British scientist who carried out the research, says, “It's almost shocking how much this tells us about the changes of people's typical interests.

    “People talk less about video games as they get older, and more about politics.”

    Crown shyness(树冠羞避) is a mysterious natural phenomenon in which the crowns of some tree species do not touch each other, but get separated by a gap clearly visible from ground level. The effect usually occurs between trees of the same species, but has also been observed between trees of different species.

    There are many theories going around, most of which make sense, but no one has been able to prove without the shadow of a doubt why some trees avoid touching each other.

    In his 1955 book Growth Habits of the Eucalypts, Australian forester M.R. Jacobs writes that the growing tips of the trees are sensitive to abrasion(擦伤), which results in crown shyness phenomenon. This theory was also supported by Dr. Miguel Franco. Some experiments have shown that if trees displaying crown shyness are artificially prevented from swinging in the wind and touching each other, they gradually fill up the gaps between them.

    But while the above theory is arguably the most widespread, it's certainly not the only one. Some scientists have suggested that crown shyness is a mechanism to stop the spreading of leaf-eating insects. These pests have been known to work together and create structures that extend up to 10 cm off of tree branches in order to reach other plants, so the gaps are the trees' natural defense method.

    One Malaysian scholar studied many trees, but found no traces of abrasions, despite their clear crown shyness. Instead, he suggests that the growing tips of the trees were sensitive to light levels and stopped growing when they got too close to other trees. Plants are able to sense how close they are to other plants and in order to get more light, they give off some chemical element to stop other trees from growing too close.

    Whatever the reason, one thing is for sure: plants are more intelligent than people used to think.

    We have heard some interesting ways that 5G wireless technology might change our lives in the future.

    5G, short for the 5th generation mobile communication technology, promises Internet speeds between 50 to 100 times faster than current 4G systems. While 5G is set to be used in some limited areas of America this year, much of the world is not expected to receive widely available service until 2023.

    One project in Britain, however, is already testing this superfast technology on an unlikely group of Internet users-cows. The project was developed by American technology company Cisco Systems. It also receives money from the British government. Cisco says the program seeks to explore the future of 5G connectivity in rural areas around the world.

    Testing areas were set up at farms in three rural areas of England. The cows are equipped with 5G-connected devices (装置) that link up to a robotic milking system, which uses sensors and machine learning to fully automate the process. System designers say technology takes over after a cow feels ready to be milked and walks toward an automatic gate. The device is designed to recognize each individual cow. It then positions equipment to the right body position for milking. During the process, machines release food for the cow as a reward.

    Other 5G technology tools include automated brushes that turn on when the cow rubs up against them. Sensors also control the amount of light to the cows' living areas depending on the weather. And, an automatic feeding system makes sure the animals always get enough to eat.

    Duncan Forbes, head of the project, told Reuters that the project shows the farm's cow operations can be greatly improved with 5G technology and that the experiment provides strong evidence that 5G technology can be widely used in the future, not just on farms in Britain, but in rural communities across the world.
