You are a new manager at the American branch of your German firm in Chicago. With a few minutes to spare between meetings, you go to get a quick cup of coffee.

    “Hey, David, how are you?” one of the senior partners at the firm asks you.

    “Good, thank you, Dr. Greer,” you reply. You've really been wanting to make a connection with the senior leadership at the firm, and this seems like a great opportunity. But as you start to think of something to say, your American colleague breaks in to steal your spotlight.

    “So Arnold”, your colleague says to your boss, in such a casual manner that it makes your German soul cringe(畏缩), “So what's your Super bowl prediction? I mean, you're a Niners fan, right?”

    The conversation moves on, and you walk silently back to your desk with your coffee. You know how important small talk is in the U.S., and you feel jealous of people who can do it well.

    There's nothing small about the role that small talk plays in American professional culture. People from other countries are often surprised at how important small talk is in the U.S. and how naturally and comfortably people seem to do it — with peers, men, women, and even with superiors. You can be the most technically skilled worker in the world, but your ability to progress in your job in the United States is highly dependent on your ability to build and maintain positive relationships with people at work. And guess what skill is critical for building and maintaining these relationships? Small talk.

    What can you do if you are from another culture and want to learn to use small talk in the U.S. to build relationships and establish trust? Work hard to hone(磨练) your own version of American-style small talk. Watch how others do it. You don't have to mimic what they do; in fact, that would likely backfire because people would see you as inauthentic. But if you can develop your own personal version, that can go a long way toward making you feel comfortable and competence．

    Let's face it. No one drinks diet sodas for the taste. People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it. Yet it seems to have exactly the opposite effect, according to a new study.

    Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet sodas. ＂What we saw was that the more diet sodas a person drank, the more weight they were likely to gain,＂ said Sharon Fowler.

The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.

    While the findings are surprising, they also offer some explanations.

    Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet sodas, they don't lose weight at all. ＂We weren't seeing weight loss necessarily, and that was confusing to us,＂ said Rogers.

    So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet sodas, and so over-compensate for the missing calories.

    A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice. ＂Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky,＂ said Helen P. Hazuda, professor at the University of Texas's school of medicine. ＂They may be free of calories, but not of consequences.＂

    How much television do you watch? Did you really give an honest answer? A recent study shows that people aren't totally truthful about their television-watching habits.

    The study in question was conducted at Ball State University in the US. Researchers there wanted to find out how much television people view according to their age. The study was paid for by a council associated with the Nielsen Company, which determines television ratings. The conclusions were that people spend more than 8 hours a day looking at a screen. This included cell phones and computers，but the majority were television screens.

    There are three interesting things about this study. The first is that people are exposed to more than one hour of advertisements per day. The second is that even with access to DVDs and internet videos, television is still the most popular media source. The third is that the amount of screen-watching people do is relatively the same from the ages of 18-65.

    So, if everyone is watching television, why lie about it? Well, if someone admits they watch television for five or six hours, they could be considered a couch potato. Michael Phillips, one of the study's main researchers, says, “There's a social stigma for people who watch too much television. Sometimes, however, watching the latest reality show or the funniest sitcom gives co-workers and friends fun things to talk about.”

    Even if you do watch a lot of television, perhaps we can use this study as a reason to be honest with ourselves about how much time we spend in front of the television. I mean, after all, everyone else is doing it...

    You may not have heard of it before, but solid rain (固体雨)has been helping Mexican farmers fight droughts(干旱) for over ten years. The magic solid rain looks like sugar and it can take in water up to 500 times as its own size and keep it in the ground for up to a year.

    The story of solid rain began in 1970, when American scientists developed a product used to take in water and help keep babies' bottoms dry. However, a Mexican chemical engineer saw this magic product as an opportunity to fight the drought. He developed a different kind of the product, which could be mixed with soil and slowly feed water to crops over a long period of time. His company, Solid Rain, has been quietly selling the product to Mexican farmers for over 10 years.

    Solid rain seems to be working wonders in Mexico. However, it has not come into use around the world. Well, that's mainly because a lot of people still don't know about it. The Mexican company has invested (投资) almost nothing into marketing, relying instead on word of mouth between Mexican farmers. However, recently, they have gotten requests from other dry countries like India and Australia.

    Solid rain has received the Ecology and Environment Award, but it has also received some negative views. Dr. Linda Scott says that the product is hardly new and that there is no scientific evidence that it can hold water for a year or last in the ground for ten years. Besides, solid rain can cause more harm than good in certain conditions.

    However, real-life use seems to show that solid rain is actually of great use to their farms. Frank Torres, a former green bean farmer used to rely on it even though drought wasn't such a big issue. He said that the production had increased by 50%.

    Kids are cool to wear blue jeans and T-shirts today. It is fashionable like that. Fashion refers to the styles of dress that are currently popular. Fashion goes beyond just clothes, though. It's important for some people to wear only the latest fashions and styles. For others, though, keeping up with trends isn't that important. The one thing that stays the same with fashion is this: it always changes!

    During the 1960s and 1970s, Hippies made bell-bottomed blue jeans (喇叭裤) popular. Also, in the 1980s, Michael Jackson made parachute pants (降落伞裤)all the fashion. Now try to find these items in today's clothing stores!

    Do you know why fashions change? The answer is probably as simple as the fact that people change. Over time, the new replaces the old People are influenced greatly by popular culture, including athletes, musicians, movies stars, as well as popular films, television shows, books and music. We are also influenced by the fashion industry's advertising.

    The stars of popular culture are always searching for a new angle to maintain (保持) their popularity. Often these new angles come in the form of new clothing or hairstyles. When people see these new styles, they often want to imitate (模仿) their favorite stars. To do so, they seek out the latest fashions to make themselves look like the people they want to imitate. In this way, fashions evolve and change over time.

    Clothes have been used to separate people into groups for many years. Even today, brand-name, clothing that is more expensive than other types of clothing can be used by some people to make themselves different from others.

    Unfortunately, this can often have the effect of distancing certain groups from others. Don't forget that it's always OK to develop your own sense of style that is unique and separate from what the fashion world determines! Stay true to yourself and let your personality - not your clothes - speak for who you are!

    No one can deny that buttons are an important clothing device. But, can they rise to the level of art? Organizers of an exhibit in New York City think so.

    Peter Souleo Wright organized “The Button Show” at Rush Arts Gallery in the Chelsea neighborhood of Manhattan. Eleven artists used the small, ordinary objects to create sculptures, portraits and wearable art. Some of the works are political, some are personal and others are just fun.

    Wright said each artist reimagines and repurposes the buttons to make art. “What I tried to do with this show,” he said, “was to look at artists who were promoting that level of craft.”

    He said he wanted the button art to be comparable to a painting “because of the amount of detail and precision in the work.”

    Artist Beau McCall produced “A Harlem Hangover”. It looks like a wine bottle that fell over on a table. A stream of connected red buttons hand over the side, like wine flowing down. Similar red button form a small pool on the floor.

    McCall layers buttons of different shapes and sizes to create the bottle. The stitching that holds them together is also part of the artistic design.

    For San Francisco-based artist Lisa Kokin, buttons are highly personal. After her father died in 2001, she created a portrait of him using only buttons. That memorial to her father led to other button portraits, including those of activists Rosa Parks and Cesar Chavez.

    Others use buttons for details. Artist Amalia Amaki of Tuscaloosa, Alabama, placed them on and around old photographs. Los Angeles artist Camilla Taylor attached buttons to three large sculptures that look like headless animals with long, narrow legs.

    “The Button Show” ends at March 12. The Rush Philanthropic Arts Foundation paid for the exhibition. The foundation was created in 1995 by the Simmons brothers: artist Danny, hip-hop producer Russell and rapper Rev. Run. The foundation seeks to bring the arts to urban youth and to provide support for new artists.
