As the new semester begins, millions of college students across the country are trying hard to remember how best to write a paper or, more likely, how best to delay that paper.

    Procrastination is the thief of time and a lot of students suffer form it. They can spend whole days in the library doing nothing but staring into space, eating snacks, surfing the Internet, watching videos and looking at other students sitting around them, who, most likely are doing nothing either.

    Paralyzed (使失去活力) by their habit to procrastinate, they write micro blogs about their fears, asking their online friends if they sometimes have the same issue. But this does nothing to break the spell (魔咒).

    According to a recent report, 95 percent of us procrastinate at some point and 20 percent of the world's population are always procrastinating. The figures are disappointing. Procrastinators are less wealthy, less healthy and less happy than those who don't delay. Procrastinators like to find excuses to justify their behavior, but BBC columnist Rowan Pelling says they are all wrong.

    Many procrastinators tell themselves they are perfectionists who work best under pressure. Pelling says this is non sense, as work done at the last minute is more likely to have mistakes than work done on time. The behavior of procrastinators often makes them feel ashamed, inconveniences others and annoys loved ones.

    Pelling also points out that procrastination feels particularly delinquent（过失的） in a society that thinks of speedy action as admirable, and, at times, even as a moral good.

    Fortunately, social scientists have thrown their weight behind efforts to understand this behavioral mistake and offer strategies to control it. Piers Steel, a Canadian social scientist and author of The Procrastination Equation, believes human is “designed” to procrastinate. Nevertheless, he suggests a couple of good ways to get through the task at hand.

    Is Paperless Office Really Paperless?

    A rising economy increased paper sales by 6 to 7 percent each year in the early to mid-1990s, and the convenience of desktop printing allowed office workers to indulge anything and everything. In 2004, Ms. Dunn, a communications supplies director, said that plain white office paper would see less than a 4 percent growth rate, a primary reason for which is that some 47 percent of the workforce entered the job market after computers had already been introduced to offices.

    For office innovators, the dream of paperless office is an example of high-tech arrogance（傲慢）. Today's office service is overwhelmed By more newspapers than ever before. After decades of development, the American government can finally get rid of the madness on paper. In the past, the demand for paper has been far ahead of growth in the American economy, but the sales have slowed markedly over the past two to three years, despite the good economic conditions.

    “Old habits are hard to break,” says Ms. Dunn. “There are some functions that paper serves where a screen display doesn't work. Those functions are both its strength and its weakness.” Analysts attribute the decline to such factors as advances in digital databases and communication systems. Escaping our craving for paper, however, will be anything but an easy affair.

    “We're finally seeing a reduction in the amount of paper being used per worker in the workplace,” says John Maine, vice president of a paper economic consulting firm. “More information is being transmitted electronically, and an increasing number of people are satisfied that information exists only in electronic form without printing multiple backups.”

    To reduce paper use, some companies are working to combine digital and paper capabilities. For example, Xerox is developing electronic paper: thin digital displays that respond to a stylus, like a pen on paper. Marks can be erased or saved digitally. Even with such technological advances, the increasing amounts of electronic data necessarily require more paper.

    “The information industry today is composed of a thin paper crust surrounding an electronic core,” Mr. Saffo wrote. The growing paper crust is most noticeable, but the hidden electronic core is far larger and growing more rapidly. The result is that we are becoming paperless, but we hardly notice at all. “That's one of the greatest ironies of the information age,” Saffo says. “It's just common sense that the more you talk to someone by phone or computer, it inevitably leads to a face-to-face meeting. The best thing for the aviation industry was the Internet.”

    Explorers had been landing in America for some time before English settlers arrived in what is now Jamestown, Virginia, in 1607. But it was in that spot on the James River that English colonization(殖民化) began, and with it, the history of America.

    James I was the king of England at that time, and he had granted approval for a group of businessmen who were part of the Virginia Company to settle in this new land. In all, 214 people set sail for America. They reached it on May 14, 1607. Very soon after they landed, the English found themselves under attack from Algonquins, a native American tribe(部落) who had been living in that area for some time. The English managed to drive off the attackers and stay there.

Under the leadership of Captain John Smith, the English built a fort(城堡)and other buildings designed to protect their new colony. They also found friendly native Americans, like Powhatan, who was willing to trade with them.

    There was a terrible winter in 1609 and only 60 of the 214 settlers survived, which was also hard on Powhatan's tribe and other neighboring native Americans.

    One of the main crops grown by the English settlers was tobacco, which they sold to native Americans and to people back in England, beginning in 1612. Tobacco became a very popular crop because it was easy to grow and because it brought in so much money.

    Once the money started flowing in regularly, the Jamestown colony grew, as did other settlements in Virginia and in other states along the eastern coastline.

    America's first elected assembly (议会), the House of Burgesses, met in Jamestown for the first time on July 30, 1619. The year 1619 also saw another significant development: the first arrival of black workers on boats from Africa. These men and women were originally servants, who worked a small piece of land for a few years and then got to keep the land as owners. Jamestown was also the capital of Virginia and remained so until 1698.

    About a month after I joined Facebook, I got a call from Lori Goler, a highly regarded senior director of marketing at eBay. She made it clear this was a business call. "I want to apply to work with you at Facebook," she said. "Instead of recommending myself, I want to ask you: What is your biggest problem, and how can I solve it?"

    My jaw hit the floor. I had hired thousands of people over the previous decade and no one had ever said anything remotely like that. People usually focus on finding the right role for themselves, with the implication that their skills will help the company. Lori put Facebook's needs front and center. It was a killer approach. I responded, "Recruiting is my biggest problem. And, yes, you can solve it."

    Lori never dreamed she would work in recruiting, but she jumped in. She even agreed to trade earnings for acquiring new skills in a new field. Lori did a great job running recruiting and within months was promoted to her current job, leading People@Facebook.

    The most common metaphor for careers is a ladder, but this concept no longer applies to most workers. As of 2010, the average American had eleven jobs from the ages of eighteen to forty-six alone. Lori often quotes Pattie Sellers, who came up with a much better metaphor: "Careers are a jungle gym, not a ladder."

    As Lori describes it, there's only one way to get to the top of a ladder, but there are many ways to get to the top of a jungle gym. The jungle gym model benefits everyone, but especially women who might be starting careers, switching careers, getting blocked by external barriers, or reentering the workforce after taking time off. The ability to create a unique path with occasional dips, detours (弯路), and even dead ends presents great views of many people, not just those at the top. On a ladder, most climbers are stuck staring at the butt of the person above.

    Many of us know about Russia's Lake Baikal from our textbooks, or by listening to Chinese singer Li Jian's hit song, Lake Baikal. But over the past decade, the world's deepest freshwater lake has been in the spotlight for an extreme sport.

    Each March since 2005, about 150 people from around the world sign up for the Baikal Ice Marathon. They come to explore the lake's breathtaking beauty and challenge themselves in unpredictable conditions.

    The 26-mile (41. 84-kilometers) journey starts on the lake's eastern shore. In March, the ice is a meter thick and iron-hard. Runners cross this frozen surface, finishing on the western side of the lake.

    Known as the "blue eye of Siberia", Lake Baikal has exceptionally clear waters. This means its ice is almost perfectly transparent. "Seen from above, a runner on the ice looks as if he or she is jogging through space," The New York Times noted.

    The landscape might be beautiful, but it's also harsh. Strong winds blast (侵袭) across the lake and frostbite (冻伤) can occur within half an hour. Runners say the cold climate is what draws them. They want to test their limits.

    "When you are in such an environment, you don't have cars around you, you don't have the noise around. I think these extreme races allow you to be alone with nature," Alicja Barahona, a 64-year-old runner from the US, told ABC News.

    The location offers some strange and unique characteristics for this marathon. The finish line is visible from the start. But the endless white offers no progress markers. The race also ends with little fanfare (喧闹). Tourists crowding the ice are mostly addicted to snapping series (自拍) and just ignore the runners.

    For some runners, the absence of spectators makes the race more challenging, because it's lonely. They must fight with themselves. "You are alone on Baikal. It is your race. You are alone with yourself. All you need to do is to defeat yourself," Veronique Messina, a French runner, told the Telegraph.
