Millions of people along the US mid-Atlantic region should be preparing for severe snow, the National Weather Service has said. Forecasters say two feet of snow could fall over the weekend in some areas. A light dusting of snow on Wednesday night caused a traffic jam in Washington, but it is what lies ahead that is occupying the thoughts of millions of people living on the US east coast.

    Washington Mayor Muriel Bowser tweeted an apology to her constituents(选民), saying that the city government had “failed to use the necessary resources effectively in response to the snow-for that I am sorry.” Among those affected was President Barack Obama, whose motorcade spent an hour and 12 minutes trying to get him from an airport back to the White House-a trip that typically takes about a half hour.

    Routine commutes lasted up to three hours and some people abandoned their cars, after an inch fell-a small amount compared to what is expected on Friday and Saturday. Long queues have formed at supermarkets, as people expect shop closures over the weekend. “Heavy snow and blowing snow will cause dangerous conditions and will be threat to life and property,” the National Weather Service warned.

    Across the US east coast at a glance:

    Classes were cancelled at schools in Kentucky and Tennessee, the first states being affected by the storm.

    Washington has requested Humvees from the National Guard so that emergency responders can reach isolated(孤立的) people and places. Besides, its underground train system will close throughout the weekend.

    West Virginia Govemor Earl Ray Tomblin has activated the National Guard to assist.

    In Philadelphia, Pennsylvania officials are calling on people to keep large salt stockpiles and plough vehicles in good repair.

    The best tool needed for survival in the event you get lost when you travel is your skill of advanced planning. You must expect the unexpected and plan accordingly. Even if you are going out for just a few hours, pack enough essentials that you can stay hydrated (体内水分), fueled and prepared for any type of weather. Your essentials should include at least:

    More than enough food and water for the activity you plan.

    A compass that you know how to use. You may want a GPS device, but those sometimes do not receive a signal or the battery fails. Cell phones also likely will not work because of a lack of signal.

    Appropriate maps. Study the terrain (地形) and your planned route. Know where you are going and how you will return.

    Comfortable hiking boots, clothes that you can wear depending on the weather conditions and additional socks in case the ones you arc wearing get wet.

    A blanket, flashlight, matches kept in a water-resistant container, and other items that will help you survive overnight if necessary.

    Cheek with the local forest office for special warnings, such as fires in the area, bear sightings, flooding, trail or road closures, etc.

It's also important that once you have planned your outing, tell someone. Give them exact details of where you are going, the trail you plan to follow, when you will return, the vehicle you are driving (and where you plan to park) and how many people will go with you—do not go alone.

    If you do become lost, your most important tool is keeping a positive mental attitude.

    Four of the World's Best Futurists(未来学家)

    Kevin Kelly

    Kevin Kelly is an author. His 1994 publication, Out of Control, discusses a future where machines and systems are so complex as to be indistinguished(难区分的) from living things.

    His latest book What Technology Wants suggests that technology is not just a mixture of wires and metals but a living thing that has its own need. The book looks out through the eyes of this global technological system to discover what it wants.

    Dr Michio Kaku

    Dr Michio Kaku is a professor of theoretical physics at the City of New York and author of The Future of the Mind and Physics of the Future.

    In The Future of the Mind , he explores the frontier of neuroscience. He predicts that one day we will be able to upload the human brain into a computer. In Physics of the Future, he predicts that glasses and contact lenses will be connected to the Internet and cars will become driverless with the power of the GPS system.

    David Brin

    Science fiction author and scientist, David Brin has received awards. In 1998, he won the Freedom of Speech Award for The Transparence Society. The book concerns threats to personal affairs and openness in the information age. In a world where the police monitor public places 24 hours a day with cameras and some credit companies can sell people's financial details to anyone willing to pay, Brin warns that surveillance(监控) technology will be used by too few people in the future. He argues that the tables should be turned and the public should have access to information like who is buying financial details from credit companies.

    Dr Ray Kurzweil

    Dr Ray Kurzweil is the main inventor of the first print-to-speech reading machine for the blind. He is the director of artificial intelligence development at Google.

    Over the past 25 years, a number of his predictions have come true. In 1990, he predicted a computer would defeat a human at chess by 1998.He predicts that by the 2020s, most diseases will go away and self-driving cars begin to take over the roads.

How can I exhibit in the Atrium Gallery

    The Atrium Gallery provides a space for exhibiting a range of creative work, especially the work of our students and staff.

    We aim to promote a programme of high quality art exhibitions which reflect creative activity and research interests.

    Proposals to exhibit

    We select exhibitions by proposal submission. Selected exhibitions showcase innovative, ambitious new work that contributes to the School's learning and research activities, and is a source of pleasure and inspiration to students, staff, visitors and the wider LSE community.

    You must be a student or member of staff at LSE at the time of the proposed exhibition. LSE Arts has no dedicated source of funding, therefore we will ordinarily expect proposals to come with a minimum level of funding, to cover core exhibition costs.

    Proposals will be judged termly for exhibition the following academic term. There is a high demand for our gallery space  so please list your first choice of dates and any alternate dates that would also work.

    Proposal Submission Timescales

    When Kim Chil-doo was young, he says, he wanted to be a model. But he gave up that idea to make money. Now, at age 65, he appears in television advertisements and fashion magazines. With his gray beard and long hair, he is South Korea's first senior model.

    Kim is one of many older people in South Korea the country has the world's fastest growing ageing population. Almost half of the country's older people live in poverty. Some take low-paying jobs to support themselves after retiring. But Kim and some other seniors have shown how older South Koreans can find unusual job opportunities later in life.

    You Sung-lae is 59. When she was a child, she wanted to be an actress. But instead, she says, she got married and had children. Now she is training to appear on a catwalk to show clothes. She was wearing a bright blue jacket, orange high heeled shoes and designer sunglasses.

    You is also helping the fashion business by attracting older buyers. Older buyers have become big players. While many older people do not have much money, others have bought their homes and built savings. Now, those seniors are ready to spend some of their money on themselves.

    Some businesses are also trying to use older people's skills and experiences. For example, Cho Young-min started a company using Skype to connect older instructors in Korea with students around the world. The students are interested in learning Korean, and the instructors are interested in sharing their knowledge.

    Another man, Ji Byung-soo found success by performing a dance song on a televised singing contest. He is 77. Now he earns enough money to donate to a local support center. Last month, he danced nonstop at a youth festival in Seoul while young people called his name. "Life begins in your 70s," Ji said. "Let's be happy and have fun."

Christmas in the United States is traditionally a time of gift-giving and family gatherings. But small towns across the country have their own traditions.

Middleburg, a small town in the state of Virginia, is known for its horses. For more than 50 years, Middleburg has organized a yearly Christmas parade. Men and women ride horses through the woods and fields. They follow hunting dogs as they search for a wild fox. But first, these hunters ride in the yearly parade, wearing their bright red hunting clothes and hats.

John Hale, a citizen of Middleburg says many city people visit his town." We have a lot of people from an urban area that come to visit, but it incorporates a lot of the old traditions." The night-time hayride is one such tradition. Small groups gather under the moonlight on an open wagon (四轮马车) filled with hay (干草). The passengers sing as farm horses pull the wagon slowly across the fields.

There are some newer traditions, too. Trey Matheu works at the nearby Salamander Resort. He says a visit to Middleburg is a chance to slow down for a day. He says Middleburg can be a calming, peaceful place without tension.

"Middleburg is an opportunity to take a step back, to take a deep breath, and understand that even though life is moving on at a very fast pace, there's really an opportunity where you're allowed to step off for a little bit."

Parade organizers say more than 13, 000 people attend even in below freezing weather. But if you ask, you will hear many different reasons why people come to watch the parade:

"I come here because I'm from a small town. I like how everybody comes together."

"I live right down that street, right there. And that's my dog."

Middleburg looks its best at Christmastime. That may be why so many people return each year.
