    This Sunday in London, an American running phenomenon will hit the UK for the first time — and looks set to leave a mark. The Color Run™ series, founded in 2011 by Utah resident Travis Snyder, who currently lives in Los Angeles, is a 5k with a twist: runners start in white clothing, and at each kilometer get caked in brightly colored powders (made from 100% eco-friendly and natural food-grade corn starch) thrown by volunteers.

    Snyder, 35, previously organized rock climbing events but says it was having a child that inspired him to think of an event combining fitness and pleasure. So far,  600,000 people have already taken part in Snyder's fitness festivals across the world, from Sydney to Rio de Janeiro, becoming America's biggest 5k along the way.

    What does Snyder think is its appeal? "I think sometimes people get tired of being so competitive," he says. "In a running event, the person next to you is the tool that you are going to compare yourself to; whether or not you run faster than them or they run faster than you. The Color Run still has running in its basis: people still get to be out and be active. But instead of it being an exclusive experience, it's an inclusive experience, where the people next to you are part of that."

    The events attract a large population, including families and children, along with a higher proportion of women than most runs. For many, it is their first race and furthest distance. Synder's eight-year-old son has taken part in 20 of the races. "It's not a big deal because he doesn't think of it as 5k – he is just running and having fun."

    In line with this theme of participation rather than competition, there are no praises for coming first. If runners want to get a result, they will have to track it themselves, as it is not officially timed. And, needless to say, the finish line is one big party – before the clean up begins.

—What is going on over there?

—They are arguing ________ each other ________ private affairs.

    Bars are very important in providing a place where people can meet and make friends. People who enjoy a drink in a local bar are happier and have more friends. They are more likely to be engaged in conversations in small community pubs, and social skills improve after a drink.

    Professor Robin Dunbar of Oxford University said, “Friendship and communities are probably the two most important factors influencing our health and well-being. Making and maintaining friendships is something that has to be done in the real world. The digital world is simply no substitute(n.替代物). Given the increasing tendency for our social life to be on the Internet rather than in real life, having relaxed, accessible places where people can meet old friends and make new ones becomes even more necessary.”

    Tim Page, chief executive of CAMRA, said, “Bars offer a social environment to enjoy a drink with friends in a responsible community setting. The role of community bars in ensuring well-being cannot be overstated. For that reason, we all  need to do what we can to ensure that everyone has a ‘local' near to where they live or work.”

    Bars have long been part of British society and have played a key role in British social life since the 16th century. Bars came to represent the heart and soul of a community, providing both a place of entertainment and an engine for community bonding. In a world before the arrival of the motor car, the bar provided a venue in which people could get friendships and a sense of community.

    But the closing decades of the 20th century witnessed major changes in both the style of bars (for example, themed bars) and their numbers. As of 2015, the number of bars declines sharply, with bars continuing to close at an average rate of 29 a week.

Most students think it to join the English corner, though a few haven't realized the of it. (significance)

Look back, I realized that it was my overconfidence which led to my failure. Only if we are modest but work hard will we have the chance to achieve our goals.
