How could you be "just ahousewife" when the basic social unit of society depends on you and yourservice? A housewife works for the longest hour, supporting your husband, childstudies, caring for eld-ers, managing finances, paying bills, grocery shopping,cooking according to individual taste, cleaning, etc. A housewife could beanyone: daughter, wife, mother, teacher, financial advisor, fashion designerand nurse, gardener, driver, cook, and so on. Don't think you are not being paid for it.  You get the re-ward that no money canoffer-the love and affection of your family, their trust in you, ahappy home and your own satisfaction.

    It is you who choose to be in thisoccupation, willingly or for any other reason. After a busy day, all wait to return to the comfortable home set by you.They know you will be there to absorb all their stress and tiredness and relaxthem. Would the life have been the same had you been working outside to earnsome money? Would you along with your family have been able to buy all thecontent in life that you are enjoying now with that money?

    Respect yourself for what you are. Introduce yourself to the world with the same dignity. The world understandsthe importance of your job; it's time to make them accept it. Introduceyourself with pride and with twinkle in your eyes "I am a housewife".Kick that "just" out.

    IPhone owners are vainer（虚荣）and spend more on clothes and grooming（仪容）than those who have BlackBerrys and Android phones, new research claims.BlackBerry owners earn the most and are more likely to have long-term relationships, while people with Android handsets are most creative and the best cooks.

    The study, carried out by TalkTalk Mobile, surveyed 2,000 owners of the three major smartphone brands to determine whether the choice of handset was an extension(延伸) of their personality. The study rated users in various walks of life using a point scoring system including personalities, daily habits and the type of industries they work in.

    Other results from the study found that people with an iPhone are more image conscious and generally consider themselves more attractive than those with other handsets. They are most likely to describe themselves as adventurous, bright and are most likely to work in media, publishing and education. They also believe their boss rates them highly. Apple owners also tend to have done more travelling and are the most active on social media sites.

    BlackBerry owners were found to be the least punctual(准时的), but despite putting in the least hours at work they are the most active phone user—sending more texts and making more calls in the average day than any other phone user. They are more social and have more friends overall. They also earn nearly two and a half thousand pounds a year more than other smartphone owners, with an average salary of $27,406. BlackBerry users classed themselves so loud and mainly work in the health, finance or property sectors. They were also found to drink more tea and coffee each day than any other phone user.

    Android owners were found to watch more TV than others and drink the most alcohol—consuming more in an average week than iPhone and BlackBerry drinkers. They have the most jobs in engineering, the government and public services and environmental services. They have the best manners and are more shy and relaxed than their counterparts.

    Dan Meader, Director of Mobile at TalkTalk, said,“Many of us have our mobile phones on us almost constantly so they do become an extension of us in many ways. It's interesting to see then how the choice in handset may reflect different aspects of personality and the results do show some unusual difference

    Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger , but we also affect our water supply in less obvious ways. You may wonder how paving(铺砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave ，the less water can flow into the ground to become groundwater.

    Human activity is not responsible for all water shortages(短缺). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs.

    Thinking about the way we use water every day can make a big difference, too In the United States , a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there's a lot we can do to lower the number.

    You can take steps to save water in your home. To start with use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗机)only when it is full 。Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.

    Many years ago, people relied on the sun, the moon and stars to find their way around. Later, the compass was introduced. And now, we have satnav（卫星导航）systems to guide us. A satnav system uses groups of satellites to show the user's location. They send information to a receiver, such as a smart phone, to show us where we are.

    The earliest built satnav system is the Global Positioning System, which belongs to the US. Then there is Russia's Global Navigation（导航）Satellite System, the European Union's Galileo and China's own satellite navigation system, BeiDou.

    On October 14, 2017, an ARJ21-700 plane, which was the first domestically-produced jet equipped with the BeiDou navigation system, successfully completed a test flight. The results showed the performance of the system developed by China matches that of similar systems produced abroad, according to the Commercial Aircraft Corporation of China.

    Since its introduction in 2000, the Beidou navigation system has seen increasing numbers of applications linked to everyday life, from shared bikes to farming.

    When it comes to shared bikes, smart locks that support BeiDou chips offer more accurate positioning than others, making it easier to find a bike.

    Farmers can use BeiDou-enabled tractors to plow（犁）the soil and use unmanned aircraft with BeiDou to sow seeds, which can improve efficiency and make better use of resources. BeiDou's farming applications have spread from Heilongjiang province to Beijing, Liaoning, Shanxi, Hubei and other regions across China.

    With its many uses, the Beidou navigation system is even playing a big role in the Belt and Road Initiative（— 带—路）. “To date, the BeiDou system has covered most parts of the Asia-Pacific region, as well as counties along the Silk Road Economic Belt and the 21^st Century Maritime Silk Road” said Yang Changfeng, Chief designer of the BeiDou system.

    Today, there are more than 20 BeiDou satellites above our heads, and China plans to launch even more this year to expand the BeiDou network to better serve the Belt and Road Initiative.

    “As BeiDou expands its overseas reach, it will be increasingly popular in the logistics （物流）industry,” said Miao Qianjun, secretary-general of the navigation services association. “Ships, for example, can use it to position themselves while sailing across oceans to European countries, no longer limited to Southeast Asian regions in the near future.”

    When it comes to gift-giving, not only must the gift giver attempt to infer the recipient's(接受者的) tastes, needs, desires, and reactions, the gift selection may also be affected by the information which it would appear to convey about the giver and the giver-recipient relationship. The ancient practice of gift-giving is still common and important in modern cultures. For instance, Lowes Turner. and Willis (1971) mention a series of British Gallup Polls from 1963-1967, in which it was found that over 90 percent of the adult population did some Christmas gift-giving each year.

Gift-giving has been treated from a variety of related theoretical aspects. A famous theoretical analysis of the gift-giving process is an essay by French anthropologist- sociologist Marcell Mauss(1923). Based on his examination of gift-giving, Mauss concluded that gift-giving is a self-perpetuating(不停的) system of reciprocity. More specifically, Mauss summarized three types of obligations (义务): the obligation to give; the obligation to receive; the obligation to repay.

    The obligation to give may be based on moral or religious necessities, with the need to recognize and keep a status hierarchy(等级制度) or the need to establish or keep peaceful relations. Receiving is seen as similarly obligatory. Mauss noted however that there is a certain tension created in receiving a gift since acceptance is an implied recognition of dependence on the giver. This tension may then be reduced by meeting the third obligation, the obligation to repay. Failure to repay or failure to repay adequately results in a loss of status and self-esteem. Adequate or overly adequate repayment, on the other hand, creates an obligation to repay on the part of the original giver, and the cycle is reinitiated.

    Schwartz (1967) noted that beyond the functions served by the general process of gift exchange, the characteristics of the gift itself also act as a powerful statement of the giver's perception(洞察力) of the recipient. He also suggested that acceptance of a particular gift constitutes an acknowledgment and acceptance of the identity that the gift is seen to imply. Among children this may lead to lasting changes in self-perceptions, but probably gifts have less influence on the self- concept of an adult.

    There can be little doubt that gift-giving is a common experience in human life and consumer behavior.

    Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO (United Nations Educational, Scientific and Cultural Organization) recently set

    April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying voice across cultures.

    Despite the celebrations, though, in the U.S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger genera-tions. It's Jason Moran's job to help change that. As the Kennedy Center's artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.

    “Jazz seems like it's not really a part of the American appetite.” Moran tells National Public Radio's reporter Neal Conan “What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore. It's actually color, and it's actually digital.”

    Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. “The music can't be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same.” says Moran.

    Last year, Moran worked on a project that arranged Fats Waller's music for a dance party. “just to kind of put it back in the mind that Waller is dance music as much as it is concert music.” says Moran. “For me, it's the recontextualization.

    In music, where does the emotion lie? Are we, as humans, gaining any insight (感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context,” says Moran, “so I want to continue those dialogues. Those are the things I want to foster.”
