Owning a smartphone may not be as smart as you think. It may let you surf the Internet, listen to music and snap photos wherever you are…but it also turns you into a workaholic, it seems.

    A study suggests that, by giving you access to emails at all times, the all-singing, all-dancing mobile phone adds as much as two hours to your working day. Researchers found that Britons work an additional 460 hours a year on average as they are able to respond to emails on their mobiles.

    The study by technology retailer Pixmania reveals the average UK working day is between 9 and 10 hours, but a further two hours is spent responding to or sending work emails, or making work calls. More than 90 percent of office workers have email-enabled phones, with a third accessing them more than 20 times a day. Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers confess(承认) they are on call almost 24 hours a day, with nine out of ten saying they make work emails and calls outside their normal working hours. The average time for first checking emails is between 6 a.m. and 7 a.m., with more than a third checking their first emails in this period, and a quarter checking them between 11 p.m. and midnight.

    Ghadi Hobeika, marketing director of Pixmania, said, “The ability to access literally millions of apps, keep in contact via social networks and take photos and video as well as text and call has made smartphones invaluable for many people. However, there are drawbacks. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smartphones mean that people literally cannot get away from work. The more constantly in contact we become , the more is expected of us in a work capacity(容量).”

    The Best Time to Visit These Pricey Destinations

    If you're going to shell out on a vacation, then you might as well do it right. With that in mind, we've asked a few experts for tips on when to visit some of the most expensive places across the globe. Here's what they had to say.

    Botswana

    Hotels in Botswana are second only to Dubai in terms of average cost per person, per night, at around $257. To make the most of your time there, consider an autumn visit, suggests Sarah Faith of Responsible Travel. “The heat peaks in October—this is the best time to go and see wild animals as they gather around in the Okavango Delta”, says Faith. While wildlife viewing is incredible in Botswana, there's much to enjoy away from the wilderness, too.”

    New York City

    New York is the second-most expensive holiday destination overall and the most expensive place to dine out, with an average meal for two costing around $67. Garrett, the CEO of Discover New York, suggests, “October and June have gorgeous weather, so outdoor activities are a good choice, with sailing, in-depth neighborhood walks and biking.” For great value, she advises traveling in January and February, when the city offers tons of indoor activities, from art galleries and Broadway shows to indoor sports events and thousands of dining options.

    Sydney

    With its incredible surfing beaches, dining scene and friendly locals, Sydney is always a favorite of travelers. It's also expensive. Generally, the shoulder seasons (fall and spring in the U.S.) have the most comfortable weather and fewer crowds than the December-to-February high season. But some months have particular appeal, according to Stuart Rigg, Australian travel specialist for Southern Crossings. April, for example, falls into the low season, which means you'll find hotel deals along with weather that's typically “very pleasant,” Rigg says. “Sydney also has some great events during this low season period,” he adds.

    London

    Petulia Melideo, who runs Context's London walking tours, advises booking well in advance for lower hotel rates, and suggests a wintry visit. “November is a great time for London. The weather is still tolerable—and if it gets too chilly, there are plenty of cozy pubs to pop into,” she says. Other good times to visit include June, which means fewer tourists.

    Visitors must present all carried items for inspection upon entry. After inspection, all bags, backpacks, umbrella, parcels and other items as determined by security officers must be left at the checkrooms, free of charge, close to each entrance. All oversized bags, backpacks and luggage must be left at the checkrooms near the 4^th Street entrance of either the East or West Building. These items will have to be x-rayed before being accepted. Items of value, such as laptop computers, cameras and fur coats, may not be left in the checkrooms but may be carried into the gallery. We regret that the museum doesn't have enough space for visitors items larger than 17*26 inches in the gallery.

    Additional security procedures and checks may be taken according to the decision of the gallery.

    *For the safety of the artworks and other visitors, nothing may be carried on a visitor's back. Soft front-baby carriers are allowed, but children may not be carried on shoulders or in a child carrier worn on the back. Wheelchairs are available free of charge near each checkroom.

    *Smoking is prohibited. Food and drink are not permitted outside the food service areas. Unopened bottled water may be carried only in a visitor's bag. Cell phones may not be used in the gallery.

    *Animals, other than service animals, are not permitted.

    *Skateboarding is prohibited.

    *Picture-taking(including video) for personal use is permitted except in the special exhibits.

    *Please don't touch the works of art.

    If you see a group of people dancing and singing on the street or in the railway station, you don't need to feel surprised. They are a flash mob(快闪族). Who are they Are they mobs? Don't be confused by their name. Actually, a flash mob is a group of people who gather suddenly in a public place, do something unusual for a brief period of time, and then quickly disappear.

    They are usually organized with the help of the Internet or other digital communications networks. The messages may be sent to friends, who send to more people. At a predetermined time, they gather and perform some activities such as exchanging books, coming together to look at the sky, waving their hands and yelling something at the top of their voice for 30 seconds. Then, they quickly disappear before the police can arrive Using mobile phones, the flash mob can change its place if the first one has been cancelled for any reason.

    Bill Wasik, senior editor of Hamper's Magazine, organized the first flash mob in Manhattan in May 2003 and the first successful flash mob gathered on June 3, 2003. Wasik claimed that he created the flash mob as a social experiment designed to laugh at fashion seekers and stress the cultural atmosphere of wanting to be an insider or part of "the next big thing”.

    Flash mob gatherings can sometimes shock people. Such an activity might seem amusing and magical, but it also might frighten people who are not aware of what is taking place. Undoubtedly, flash mob can serve as good political tools and have great potential, such as using flash mob to advertise a product.

    The flash mob is now becoming more and more popular. People use it to do many things. Flash mobs give people from all walks of life an opportunity to come together to create a memory.

    It was Saturday morning. I heard loud noises of moving furniture in the next room. I could almost feel the excitement of John who was soon going to get a room of his own. I remember my own feelings when I was 13. I knew how much he longed for his right to privacy (私人空间) when he was sharing a room with his younger brother, Robot. He said, “Mum, Can I please have a room of my own? I could use Jeff's. He won't mind.”

    It was true that Jeff had graduated from college and flown from the nest. But would he mind? The room was the place where I told him a thousand stories and we had a thousand talks. As close as we were, though, the time came when Jeff needed a door between us. His life was spreading into areas that had less to do with family. I no longer could-or should-know everything about him.

It turned out that getting Jeff's permission was easy. He said, “Of course, Mum, it would be selfish of me to hold on to it.” Then his voice softened, “Mum, I won't be living at home again—you know that.” Behind his glasses, his eyes were lit with all the love. There were no doors closed here—they had all opened up again.

    As John and I were cleaning the room, I fixed my eyes on Jeff's things around me and could almost touch the little boy who I knew was gone forever. I looked at the room and, in my heart, I let it go. To hold on would be, as Jeff said, selfish. Now it was time for John, shouldering through the door, his eyes bright with promise of independence, to disappear behind the door. It was time for letting go to happen again.

    When Veronika Scott was a student at the College for Creative Studies in Detroit, Michigan, she received a task to “design to fill a need.” She dreamed up an idea for overcoats that would double as sleeping bags, made 25 of them, and handed them out to people living in shelters on an abandoned city playground. While her efforts were greeted mostly with enthusiasm from those braving Detroit's cold winters, one woman voiced dissatisfaction. “We don't need coats; we need jobs,” she told Veronika. Then she had her second inspiration.

    After graduating from college in 2012, Veronika founded the Empowerment Plan, a nonprofit organization. She hired two homeless women to sew the coats and paid them with donations she received through her blog. Now, the Empowerment Plan employs about 20 people and has produced more than 10,000 coats and distributed them in 30 states, Canada, and elsewhere abroad.

    “We don't require previous employment,” Veronika says. “We're looking for people who are motivated.” The Empowerment Plan provides free classes and lends money to those who qualify. Nearly all the employees eventually move into permanent housing, and some go on to jobs in the auto industry and construction.

    Veronika has bettered the coat's design by making its outer layer of a lightweight material that resists air, wind, and water and its inner layer of a material that stores body heat. Still, Veronika is less focused on the coats than on the workers who make them. “At the end of the day,” she says, “the coat is a vehicle for us to employ people.”
