    People are less willing to rely on their knowledge and say they know something when they have access (接近) to the Internet, suggesting that our connection to the web is affecting how we think.

    Professor Evan Risko, of the Department of Psychology at the University of Waterloo, led a recent study where the team asked about 100 participants (参与者) a series of general-knowledge questions, such as naming the capital of France. For half of the study, participants had access to the Internet. They had to look up the answer when they responded that they did not know the answer. In the other half of the study, participants did not have access to the Internet.

    The team found that the people who had access to the web were about 5 percent more likely to say that they did not know the answer to the question. Furthermore, in some cases, the people with access to the Internet reported feeling as though they knew less compared to the people without access.

    “With the popularity of the Internet, we are almost frequently connected to large amounts of information. And when that data is within reach, people seem less likely to rely on their own knowledge,” said Professor Risko.

    Studying the results, the researchers thought that access to the Internet might make it less acceptable to say you know something but are incorrect. It is also possible that participants were more likely to say they didn't know an answer when they had access to the web because online searching offers an opportunity to confirm their answer, and the process of finding out the answer is rewarding.

    “Our results suggest that access to the Internet affects the decisions we make about what we know and don't know,” said Risko. “We hope this research helps us understand how easy access to large amounts of information can influence our thinking and behaviour.”

    Anyone can try to lead a group, but not every individual is cut out for leadership. The better leaders possess a few qualities that can mean the difference between the success and failure of the group. These are the qualities the leader of higher rank will look for when choosing a leader for a group, or when evaluating the performance of a leader. They're also the qualities team members want in a group leader, and appreciate when they find them.

    Take Responsibility

    Group leaders might share tasks around a group as necessary, but eventually a group leader needs to be able to accept that responsibility lies on his shoulders. That means that if things go wrong in a group project, he's the one who must accept the consequences and work out what mistakes are made. The group leader won't always have the power to control everything group members do, but he should be ready to admit any mistakes the group has made as a result of his leadership

    Concern for Members

    The group leader has a commitment to the task or project at hand, but perhaps more importantly, he has a real concern for each and every person who is part of his group. This means getting to know the strengths, weaknesses and goals of team members, as well as making time to build the group through collective activities. The group leader should make sure that everyone is included, even if an individual is new to a group.

    Good Listener

    The group leader needs to be able to listen to the suggestions, complaints and ideas of group members. Not only will this allow complaints to be addressed and potentially suitable ideas to be put into practice, but a leader who listens will also encourage group members to share their concerns and thoughts, creating an atmosphere of free speech and productivity.

    In recent years, China has witnessed the growth of luxury (奢侈品) brands. In this market, Chinese consumers are now the largest spenders. It's clear that a new generation of young, materialistic people is increasingly relying on luxury brands to improve its self-image.

I am a fashionist too, at least in spirit—I love to look at clothes and shoes. But I don't understand why people spend lots of money on designer labels.

    When a young woman buys a handbag that costs two months of her salary, that's a scary thing.

    What's interesting is that scientists have found that having luxury things doesn't lead to happiness.

    Study after study has shown that although we want material things, when we get them we don't suddenly become "happy" people. In fact, a series of studies by Leaf Van Boven at the University of Colorado, US, has shown that individuals who spend money on travel and similar experiences get more pleasure than those who invest it in material things. That's because experiences are more easily combined with a person's identity. If I travel to Yunnan, that adventure affects how I think in the future. My memories become a part of me.

    Moreover, as Van Boven has observed, young people who pursue happiness through "things" are liked less by their peers. People prefer those who pursue happiness through experiences.

    It's natural to want to express yourself through your appearance. So my advice is: create a look that isn't tied to a designer label. Convey your own message. Take some lessons from the late Apple co-founder Steve Jobs. He was always in Levis jeans and a black turtleneck. Mark Zuckerberg, founder of Facebook, routinely appears in hoodies and sneakers. These people, successful people, have style. You don't have to break the bank to send a message about who you are.

    Take a trip. Go out into the world. Then come back and confidently create your own signature look.

Do you know that junk food isn't healthy? Of course you do! Do you eat it anyway? Of course you do! But a new study shows teaching adolescents about the ways food companies fool them into thinking junk food is cool can encourage kids to fight back—by eating healthier.

The pull of junk food can be super-strong. It's designed to be tasty, which makes eating well one of the great health challenges of our time. Everyone from doctors to the government has been trying to handle it. Yet we keep eating junk food.

Professor Christopher Bryan says, "Food companies want you to want junk food." They spend millions of dollars coming up with new ways to promote junk food consumption. They hire scientists to make new junk food almost irresistible. They might do this, for example, by adding more sugar. Rats fed junk food for six weeks will even walk across a floor that gives them electric shocks just to get more of such food.

Food ads often make unhealthy junk food seem healthy by featuring professional athletes, fit-looking pop stars and smiling, active teens. "We thought when the students learned this, it would matter to them," Bryan says. He worked with 8th graders at a Texas school. Half of them got a lesson Bryan created. It focused on the ways junk food is advertised, or marketed. A second group received lessons that focused on health. These lessons informed students junk food is bad, and that foods like apples or carrots are a better choice. The students learned a bad diet can lead to major weight gain, and that being overweight puts people at risk for serious diseases. They also learned how eating well now can keep you healthy when you're older.

After the lessons, the kids in both groups were asked how they felt about junk food. Most didn't have positive feelings about these unhealthy foods.

Hip-hop started 50 years ago as an escape from poverty and violence in Bronx, New York City. The music and style appealed to Black and Latino teenagers. As hip-hop spread throughout New York, so did the culture.

People often mix up hip-hop with rap. Rap is a musical style that combines quick recitation of rhymes with musical beats. But hip-hop is more than just music. It is a culture, and rap music is one part of it. Hip-hop also includes other activities, like breakdancing, disc-jockeying and graffiti art. In his 1993 song Hip Hop vs. Rap, KRS-One said: "Rap is something you do. Hip hop is something you live." In the early days of hip-hop, playing music on the streets or turning a basketball court into a dance floor may have seemed like a simple invitation to have fun and party. But it actually was an answer to social and economic injustice in poor neighborhoods. It was a way to show joy and imagination even without resources and wealth.

As hip-hop and rap music grew into a force in American culture, entertainers used it to speak to their personal realities. In 1982, in the song The Message, Grandmaster Flash and the Furious Five criticized poverty and a lack of investment in Black communities. Several years later, Tupac Shakur complained about police violence in the song Changes. Today, hip-hop's influence on music and other industries is so widespread that experts say it becomes difficult to measure.

There is also hip-hop's influence on protest, resistance and political dissent(异议)around the world. From the Arab Spring and the Palestinian freedom fight to feminism and class struggles, rap music is a popular expression for calls to action. Music videos produced by artists in Africa, Europe, Asia and South America often include breakdancers, graffiti and other elements of hip-hop.

"Hip-hop took the chains off us and said, ‘No, we're gonna say it our way,' " Al Sharpton, American civil rights leader, said, "It was that freedom. It was that raw, non-watered down kind of expression."
