A Dutch artist and designer has come up with a device which he hopes will get rid of pollutants from Beijing's smog skies, creating clean air for the city's mask-wearing people.

    An electromagnetic field（电磁场） will pullparticles（微粒） in the smog to the ground where they can be easily cleaned.

“It's like when you have a balloon which has static（静电） and your hair goes toward it. Same with the smog,” says artist Daan Roosegaarde.

    His studio has reached an agreement with the Beijing government to test the technology in one of tile capital's parks.

    With its skies regularly covered by dirty gray smog, Beijing this week announced a series of emergency measures to handle the problem.

    Roosegaarde says an indoor model device has already proven it works and is confident that the results — with the help of a team of scientistsand engineers — can be replicated outside.

  “Beijing is quite a good place because the smog in Beijing is quite low. It lies in a valley so there's not so much wind. It's a good environment to explore this kind of thing.”

  “We'll be able to purify the air and the challenge is to get the top of the smog so you can see the sun again.”

    Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem, rather than a practical solution to Beijing's awful air pollution.

  “This is not the real answer for smog. The real answer has to do with clean cars, different industry and different lifestyles.”

    However, he hopes the project will make a “fundamental statement” by allowing the city's people to realize the difference between breathing clean and smog-filled air.

    Queensland is one of the most amazing states in Australia. It has some of the most beautiful natural scenery on the planet, with the Great Barrier Reef, rainforests and impressive beaches.

The Great Barrier Reef

It is one of the world's largest natural features. It stretches more that 2,300 km along the north eastern coast of Australia from the northern tip of Queensland to just north of Bundaberg. The things that most surprise visitors to the reef are the colors.

Without doubt, the best way to see the Great Barrier Reef is by diving. If you have a little extra money and you are feeling a bit lazy, you can fly over the reef in a plane.

Fraser Island

Another area of natural beauty is Fraser Island. This is the world's largest sand island. It's best visited from Hervey Bay on the mainland, where there are a number of places offering trips around the island. To fully appreciate Fraser Island you should go for three or four days. Attractions include some beautiful fresh-water lakes, particularly Lake Wabby and Lake Mckenzie. You can walk around these on white sands untouched by human footprints. Indian Head also has some beautiful views. Braver travelers can go and watch sharks circling the water hundreds of meters below.

The Whitsunday Islands

    It would be a pity to travel around Queensland without taking a trip around the Whitsunday Islands. They were named by Captain Cook in 1770, after the day on which he arrived. Here are some of the great things you can do there.

●Cruise around them on a relaxing trip.

●Take a sailing course.

●Look at the aboriginal (土著的) paintings in caves on Hook Island.

●Have fun in the water doing lots of water sports.

    So, will you be going to Queensland?

    A five-year-old dog named Kelsey has been praised as a hero for helping to save the life of her owner who slipped in the snow and broke his neck.

    The man, Bob, was alone when he left his Michigan farmhouse on New Year's Eve to collect firewood. Expecting a journey of only several meters, Bob was wearing just long johns (衬裤), a shirt and slippers when he went outside, although the temperature was around -4℃.

    After the accident, he was unable to move in the snow. Fortunately, Kelsey came to his assistance.

    "I was shouting for help, but my nearest neighbor is about 400 meters away, and it was 10:30 pm, Bob explained." But my Kelsey came. By the next morning, my voice was gone and I couldn't yell for help, but Kelsey didn't stop barking."

    Kelsey's companion kept him warm by lying on top of him. She licked his face and hands to keep him awake." Kelsey kept barking but never left my side," Bob recalled. "She kept me warm. I knew I couldn't give up and that it was my choice to stay alive."

    Bob spent 20 hours in the freezing cold. When he finally lost consciousness, his dog kept barking. Finally, hearing the barking, Bob's neighbor discovered him at 6:30 pm on New Year's Day and called the emergency services at once. When Bob arrived in hospital, his body temperature was below 21℃. However, doctors were surprised to find that he didn't have any frostbite (冻疮). They believed it was because of Kelsey's determination to keep him warm, Dr. Chaim Colen, the doctor who treated Bob, said, "Animals can help and his dog really saved him... He was very fortunate.”

    Bob said he was "enormously" grateful to both Dr. Colen and his Kelsey, "They saved my life. They are truly heroes!"

    Russ Gremel, now 98 years old, decided it was time to donate $2 million to the Illinois Audubon Society, a charity to purchase nearly 400 acres of land for wildlife protection. Gremel was able to make this amazing donation because he purchased $1,000 worth of Walgreens stock seven decades ago whose value has grown recently.

    "A single man with no kids, Gremel has lived in the same Chicago house for 95 years, and has always lived simply", neighbor Patrick Falso told TODAY. Falso said he heard Gremel say many times the "money wasn't mine to begin with" and that he always intended to give it away.

    The Gremel Wildlife shelter was founded on June 4. Illinois Audubon Society president Jim Herkert said Gremel's donation was extremely generous. "It's allowing us to protect a really valuable and important possession and realize one of Gremel's wishes that we could find a place where people could come out and experience nature the way he did as a kid," Herkert told TODAY.

    After doing all this, this past weekend, Gremel adopted an old Chihuahua（吉娃娃犬）. Winnie the dog was picked up as a homeless dog several months ago. She suffered from a kind of cancer, which was treated—and all she needed was a loving home, which Colleen Collins, the founder of Perfect Pooches Adoption Agency, was determined to find.

    Gremel had lost his own beloved Chihuahua earlier this year. When he reached out to Collins about Winnie, she felt this could be a good match. That feeling grew when she brought Winnie to his house for a meet and greet, and Winnie was introduced not only to Gremel but also some of his friends and neighbors. One had brought over a lot of fresh strawberries; all said they'd be there to help out in any way needed.

    When your dream is to become a footballer, nothing should get in your way—even if you have no feet.

    Gabriel Muniz, an 11-year-old Brazil kid, was born without feet. Although his family thought he would have serious difficulties living a normal life, he started walking before he was one year old. His mother would go after him, expecting him to keep falling, but he never fell. It took him a while to make the jump from walking to playing football, but he did make it. And, in fact, there's nothing he loves more than playing football. In his school, the skillful youngster (年轻人) is not only the best player in his school team but also the captain of his gym team.

    He knows that his disability means he'll never be able to play for a professional (专业的) football team. So Gabriel is hoping that football will one day become a Paralympics (残疾人奥运会的) sport. He proved to everyone there he could go head to head with any other boy. Watching him play is unbelievable. He's fast and he's got a big bag of tricks—he's very skilled and he does everything he can to copy his hero, Messi so much that he is invited to go to Spain to meet his hero Messi and show his talent in the Barcelona Football Club.

    His coach says he is proving the disability only exists (存在) inside our heads.

    Are you familiar with the greeting, "Can I add you on WeChat?" It seems like every time we meet new friends or colleagues nowadays, the first thing that springs to mind is adding each other on the app. Nevertheless, more than 80 percent of WeChat users report feeling stressed or anxious when they receive a large number of messages, according to a study done recently by the app's developer Tencent(腾讯). In other words, WeChat can overwhelm(使应接不暇) us, while also breaking down the boundaries between our work and private lives.

    Just think how easy it is now for bosses to hand out assignments during the holiday, so long as they have your WeChat contact. When you're at the cinema enjoying a romantic movie or having a barbecue in the backyard, you can never cut yourself off from the outside world unless you switch off your phone. Not to post something in WeChat Moments before replying to your boss first!

    Apart from interrupting your leisure time, WeChat can also reduce your productivity at work. For many office workers, logging in to WeChat on their computers at the start of the day has become routine. But what if browsing the Moments distracts us from doing the work? The app steals our time without us even noticing it, making us have the false belief that we are busy all the time.

    And as if that weren't bad enough, there're the "one-off" friends who take up space on our WeChat friend list. A handy way to check how many one-off friends you have is to take a look at your chat history with them. Sometimes, you only sent the initial friend requests so you could invite them to a WeChat group or inform them of something for your boss. Yet still, as your friend count(好友数量) ever goes up, it can make you feel the need to post selfies(自拍) and share details of your life in your Moments, just so you can stay up to date.

    With WeChat, all our spare time is swallowed up by the constant torrent of messages and our attention keeps getting diverted by Moments and pop-up ads. So it's time that we should do something to nip this problem in the bud.
