Earlier this month, blogger Lisa Henderson announced that she and her husband John had decided not to have Christmas. The family, who lives in Utah, will still put up decorations, but presents from Santa are a no-go this year.

    “John and I feel like we are fighting a very hard uphill battle with our kids when it comes to their rights,” Henderson wrote on her blog. “It is one of the biggest struggles as a parent these days in middle class America. Our kids have been acting so ungrateful lately. ... John said, “We shouldn't just celebrate Christmas. And, so that's what we did.”

    Instead, the Hendersons are putting the money they would have spent on gifts toward service projects in order to teach their three sons the “pleasure of giving.” The children will still receive gifts from grandparents and other family members, but this year, she said, their letters to Santa will be asking him to find someone who needs presents more than they do.

    In an interview with ABC News, 11-year-old Caleb Henderson admitted that he and his brothers had been behaving badly. “We would hit each other. We were fighting and crying,” he admitted, and Lisa said that when she broke the news to her sons, they cried pretty hard.

    But so far, Henderson told Fox News last week, the family is having a sudden turning this into a different kind of gift. They have already held a clothing drive and sent boxes of clothes and candy to a village in the Philippines that was hit hard last year by Typhoon Haiyan.

    “The children were excited and kept wanting to give more and more,” she reported on her blog.

    Many readers responded positively to Henderson's post. Some sharing their own stories of limiting Christmas in order to teach their children to be charitable(仁慈的) or grateful. “As parents you're giving your kids something so much more special than a bunch of gifts on Christmas,” one wrote.

    But Henderson received negative follow-ups as well on her blog. Responding to critics, she updated her blog with a statement that reads, in part:

I just wanted to explain a couple of things. First, my kids are in no way hurt for things.... They have reacted by making gifts for each other and packing them into each other's stockings stealthily(偷偷地). They are learning exactly what we wanted them to learn, because they are not moving around feeling sorry for themselves. They are thinking of others.

    The second thing I wanted to explain is why I wrote this post. Some people seem to think I wrote this for attention. Ummm, the attention you get from posts like this is not good and actually extremely difficult to deal with.... The reason I wrote this post is I want to empower parents to feel like it's okay to take a stand. ... I wanted to share what we are doing, so any parents that feel they are struggling with the same issues in their home can see what others are doing and get ideas for their family. My intention is to help support other parents and to raise amazing kids.

    Many people turn to doctors or self-help books, but they ignore a powerful thing that could help them fight illness: their friends.

    Researchers are only now starting to pay attention to the importance of friendship in health. A 10-year Australian study found that old people with a large circle of friends were 22 percent less likely to die during the study period than those with fewer friends. A large 2007 study showed an increase of nearly 60 percent in the risk  for obesity (肥胖) among people whose friends gained weight. And last year, Harvard researchers reported that strong social ties could improve brain health as we age.

    “In general, the role of friendship in our lives isn't well realized,” said Rebecca, a professor at the University of North Carolina. “Friendship has a bigger effect on our psychological health than family relationships.”

    While many friendship studies are about the close relationships of women, some research shows that men can benefit, too. In a six-year study of 736 middle-aged men, having friendships reduces the risk of heart attack. Only smoking was as important a risk factor (因素) as having little social support.

    Exactly why friendship has such a big effect isn't entirely clear. While friends can send a sick person to the hospital or pick up medicine, the benefits go well beyond physical assistance. Friendship clearly has a big psychological effect. “People with stronger friendships feel like there is someone they can turn to,” said Karen, a doctor. "The message of these studies is that friends make your life better.”

A Teenage Inventor

    The world could be one step closer to quick and inexpensive Ebola detection thanks to a teenager from Connecticut.

    Olivia Hallisey, a junior at Greenwich High School, was awarded $50,000 in the Google Science Fair for her new method that detects Ebola, a virus that causes bleeding from different parts of the body and usually causes death. Olivia's method is to ask patients to put their saliva (唾液) onto a testing card. The card changes color if the person is catching Ebloa. Present Ebloa tests take up to 12 hours and cost $1,000. Olivia's method, however, can be done just in 30 minutes for about $25. Besides, the sample (样本) doesn't have to be put in a refrigerator thanks to the silk material Olivia uses to produce the testing cards.

    Olivia was inspired to deal with this global problem after watching the news that more than 10,000 people died from Ebola in West Africa. She was particularly worried about the fact that, while the acts of involvement can improve survival rates, present detection methods are costly, time-consuming and require complex tools. Olivia got help from her science research teacher. She drew out directions from past research, and figured out detection systems that have proven to work with other diseases, including Lyme disease and yellow fever.

    "What affects one country affects everyone," Olivia told CNBC. "We have to work together to find answers to the huge challenges which cause harm to the global health." The Connecticut's teen, who hopes to become a doctor one day, was named the Google Science Fair winner in the competition of 20 competitors from across the globe. The fair is open to young people between the ages of 13 and 18 in most countries.

    Olivia hopes her success will inspire other girls interested in science and computers. "I would just encourage girls to try it in the beginning, and remind them that they don't have to feel naturally drawn or feel like they have a special talent for maths or science," she told CNBC, "but just really look at something they are interested in and then think how to improve something or make it more enjoyable or relate it to their interests."

    Humans are social animals. They live in groups all over the world. As these groups of people live apart from other groups, over the years and centuries they develop their own habits and ideas, which are different from other cultures. One important particular side of every culture is how its people deal with time.

    Time is not very important in nonindustrial (非工业的) societies. The Nuer people of East Africa, for example, do not even have a word TIME that is in agreement with the abstract thing we call time. The daily lives of the people of such nonindustrial societies are likely to be patterned around their physical needs and natural events rather than around a time schedule (时间表) based on the clock. They cook and eat when they are hungry and sleep when the sun goes down. They plant crops during the growing seasons and harvest them when the crops are ripe. They measure time not by a clock or calendar, but by saying that an event takes place before or after some other event. Frequently such a society measures days in terms of "sleeps" or longer periods in terms of "moons". Some cultures, such as the Eskimos of Greenland measure seasons according to the migration of certain animals.

    Some cultures which do not have a written language or keep written records have developed interesting ways of "telling time". For example, when several Australian aborigines want to plan an event for a future time, one of them places a stone on a cliff or in a tree. Each day the angle of the sun changes slightly. In a few days, the rays of the sun strike the stone in a certain way. When this happens, the people see that the agreed-upon time has arrived and the event can take place.

    In contrast (成对比), exactly correct measurement of time is very important in modern, industrialized societies.

    This is because industrialized societies require the helpful efforts of many people in order to work. For a factory to work efficiently (well, quickly and without waste), for example, all of the workers must work at the same time. Therefore, they must know what time to start work in the morning and what time they may go home in the afternoon. Passengers must know the exact time that an airplane will arrive or depart. Students and teachers need to know when a class starts and ends. Stores must open on time in order to serve their customers. Complicated (复杂的) societies need clocks and calendars. Thus, we can see that if each person worked according to his or her own schedule, a complicated society could hardly work at all.

American country music is also known as country western music. It has a very long history. It comes from the folk songs of immigrants (移民) from Britain.

 Country music uses simple music and words to express everyday feelings such as loneliness, love, and sadness. That is to say, country music describes life. It talks about friends and enemies, trucks and roads, farm and crops. People in many parts of the world like country music, because everyone can understand what the music is about.

Country western music became popular first among cowboys (牛仔) in the American west countryside. Cowboys had to take care of cows day and night. When they were alone with the cows, they often sang beautiful and peaceful songs to calm the animals and to overcome their own fear. They were not well-educated and so they sang about their daily life in very simple words. They played guitars, violins and other instruments. In the south of America, many people added instruments from their homes, like bottles and spoons. When cowboys visited their friends and families on holidays like Thanksgiving, they usually sang and played country western music.  

In recent years, many musicians have made country western music a little different from the one in the past. These changes make the songs sound even better. Today singers such as Carth Brooks, Reba McEntire, Emmylou Harris, Lyle Lovett, Eddie Rabbitt, LeAnn Rimes, Randy Travis and a group called Alabama are singing and playing in different styles. They have brought country western music more and more fans from all over the world.
