The concept of culture has been defined many times, and although no definition has achieved universal acceptance, most of the definitions include three central ideas: that culture is passed on from generation to generation, that a culture represents a ready-made principle for living and for making day-to-day decisions, and, finally, that the components of a culture are accepted by those in the culture as good, and true, and not to be questioned. The eminent anthropologist George Murdock has listed seventy-three items that characterize every known culture, past and present.

    The list begins with Age-grading and Athletic sports, runs to Weaning and Weather Control, and includes on the way such items as Calendar, Fire making, Property Rights, and Tool making. I would submit that even the most extreme advocate of a culture of poverty viewpoint would readily acknowledge that, with respect to almost all of these items, every American, beyond the first generation immigrant, regardless of race or class, is a member of a common culture. We all share pretty much the same sports. Maybe poor kids don't know how to play polo, and rich kids don't spend time with stickball, but we all know baseball, football, and basketball. Despite some misguided efforts to raise minor dialects to the status of separate  tongues, we all, in fact, share the same language.

    There may be differences in diction and usage, but it would be ridiculous to say that all Americans don't speak English. We have the calendar, the law, and large numbers of other cultural items in common. It may well be true that on a few of the seventy-three items there are minor variations between classes, but these kinds of things are really slight variations on a common theme.

    There are other items that show variability, not in relation to class, but in relation to religion and ethnic background — funeral customs and cooking, for example. But if there is one place in America where the melting pot is a reality, it is on the kitchen stove; in the course of one month, half the readers of this sentence have probably eaten pizza, hot pastrami, and chow mein. Specific differences that might be identified as signs of separate cultural identity are relatively insignificant within the general unity of American life; they are cultural commas and semicolons in the paragraphs and pages of American life.

    The first week of my summer campaign has been quite an experience! I'm learning the ups and downs of guiding this new journey,and I'm soon finding my footing in the wonderful world of support raising.

    Some may ask: Why do you choose a job where support raising is necessary? Why not just find a ministry that will support you without having to do any extra work?

    I had a wonderful support meeting this week where I was able to have some very good conversations with the lady I was sharing with.It blessed my soul to see her eyes light up with the same passion（热情）I felt in my heart about the ministry I was sharing with her.I kept thinking in my head "I've shared my passions with her,and she gets it."At the end of our meeting she decided to become a donor,but she gave me something extra that I haven't received from anyone else.She gave me a handmade wooden cross,small enough to carry with me.

    As soon as she handed it to me,I knew it was a gift sent from God,through an act of friendship.It's a symbol of a partnership that is developing through this journey,a symbol of how God can send us messages and a symbol of new friendships to come throughout the summer and my time in the middle east.Finally,it's a symbol of the example of what it looks like to build relationships with people who will join you in sharing with the world.It's something I'll treasure through the rest of my summer campaign,through my service in the middle east,and the rest of my life.

    Every year in May, art galleries and museums prepare shows to honor Leonardo Da Vinci, who died in France on May 2, 1519. He is remembered as one of the greatest artists and creative thinkers of all time. His most famous paintings are The Mona Lisa and The Last Supper.

    Recently, researchers have been studying a painting-Landscape 8P which, they think, is Da Vinci's earliest-known artwork. They used special lighting to study the artwork and discovered there were two images(图像), not one. One drawing is on the back of the piece, which dates back to August 5, 1473.

    The drawing on the front was painted when Leonardo was 21 years old. It shows a river valley and a castle outside the city of Florence. There is little left of the drawing on the back, perhaps because it was wiped off. Only a bridge over a river can be seen. But there is writing on both sides.

    The writing on the front gives the date and goes from right to left. Some people would call this "mirror-writing". It's a way Leonardo often wrote in his notebooks. The writing on the back goes from left to right and tells about an agreement, probably to produce a work of art.

    Cecilia Frosinini is an art historian. She said, "Leonardo was born left-handed, but was taught to write with his right hand from a very young age. By looking at his writings, including from this drawing, we can see his right-handed handwriting is educated and well done. "

    Experts compared the two handwriting samples(样本)and said they were both made by Leonardo. They show he could write well using his left hand or his right hand.

    The drawing is known as Landscape 8P from its number in an art list. It will be part of an exhibit at Italy's Uffizi Gallery. The gallery director, Eike Schmidt, said by studying the drawing researchers gave us a new way of looking at Leonardo's drawing technique and his abilities in writing.

    Once again DC Comics and Warner Bros. have divided fans and critics over their latest superhero film.

    There had been worrying news about Justice League in the months before its release, with a lot of reshoots of scenes, a new director being brought in to finish the film after original director Zack Snyder's tragic loss of his daughter and, of course, a lot of talk about Ben Affleck's future in the role of Batman.

    Some people are saying that Justice League is another big disappointment, that it could have been incredible and instead fails to really entertain. Others say that Warner Bros. have finally got it right and that the future for the League looks bright.

    My opinion lies somewhere in the middle. The film was by no means a disappointment: it was exciting, funny and a lot of fun to watch. There's something special about watching the heroes from your childhood brought to life on the big screen and maybe that is affecting my opinion.

    However, I will say that a lot of work needs to be done if the producer wants to make a great success. Although the film was good, it was obvious which scenes had been reshot and how the characters had been changed. I also have to mention the several scenes in which the special effects were very badly done; these are the kinds of problems that you don't expect to see in a film with such a big budget.

    Another point to add is that it is good to see the producer making Superman slightly a brighter character and adding some jokes to the plot to keep things fun. But the producer must be careful not to make the mistake that another film producer—here, not mentioning the name—is coming very close to doing: turning all of the films into bright and colorful shows and losing a lot of seriously good stories.

    In the end, Justice League is not a perfect film but it is definitely not a terrible one. A lot of work is still to be done but I hope that DC does not completely lose its darker side.

The teenage Snowboarder.

I was born in Denver, USA. and started snowboarding aged eight when my dad took me to a resort in the mountains. About two hours from Denver. The hill looked unbelievably steep and scary. So My dad had to do a lot of persuading to get me on a board. Because I was so young. I hadn't even thought of asking him if I could start snowboarding? But he was already into it and wanted me to love it, too—-He made it look so simple, and in the end I managed just fine.

After this experience, it wasn't long before I'd developed a love of sport and had improved my ability too. I started competing aged ten. Some people entered loads of competitions and ended up getting bored of snowboarding. But my love of taking part and winning got stronger as I got older, which always help me to push myself harder. I enjoyed not having a fixed plan and sometimes this went well, like when I became the first female ever to get a perfect 100 at a local competition. I wasn't sure I'd even attempted the jumps that got me the score until I actually set off. That achievement increased my trust in my own abilities.

During the summer I focused on training and my studies while there's no snow. Although I trained daily, it's nice not having to stick to quite a strict diet like I did in the winter. I also got to spend lots of time with my friends then. It's the best way of dealing with not being able to do what I loved so much and what I was really good at.

Now. I have to think carefully about my future. Snowboarding is such a huge part of my life now. But I also feel it's important to have something else I can do. just in case I don't succeed as a professional snowboarder or I get injured. I'm wondering whether becoming a doctor is a possibility. if my active life allows time for doing a college degree, it's impossible to imagine myself growing tired of the sport. But I can't go on snowboarding my whole life.
