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.

    I look in the mirror, and I'm not happy with what I see. I don't have a "perfect" face. I look in the magazines and all I see are girls with fair hair, blue eyes, and, of course, a pretty little nose. They're on the outside of the buses that I take home, the television programs I watch, and the billboards（广告牌） I walk under. Almost every advertisement I see shows this human physical "perfection". These billboards not only tell me what to drink, but also how to look.

    Our society place more importance on a person's physical beauty, rather than their ability, honesty and character. We have influenced women to go through painful surgeries（手术）and starve themselves to become this society built physical model. To be a beautiful woman in the 21st century doesn't mean that you are a brilliant doctor or caring mother. It means you have the perfect jaw, eyes and lips. It means that you can be six feet tall and weigh one hundred and ten pounds.

But what about the women who are starting to leave their youth? Instead of looking at aging as a sign of wisdom, we try to prevent the aging process(过程）. It's a kind of funny thing to want to look eighteen when fifty. Fifty is a relaxed age, when you can step back and look at all you've achieved (successfully complete something). It is when your hard work pays off. Unfortunately, our society just sees you as "old". To stop the aging process, women buy wrinkle（皱纹） creams, do eye lifts and face lifts. They spend thousands of dollars to win the hopeless battle against age.

    I remember when I was about thirteen years old and going through teens, I had oily hair, and a half developed body. I hated the way I looked. I used to cry to my mother all the time, but she would just laugh and tell me that "you don't want anyone to like your appearance. It's your heart that is important, because beauty fades.（消逝）" I knew that she was right. If you work on your heart enough, people will start to see the beauty in you, which lasts and remains on even after you die.

    Some people think that success is only for those with talent or those who grow up in the right family, and others believe that success mostly comes down to luck. I'm not going to say luck, talent, and circumstances don't come into play because they do. Some people are born into the right family while others are born with great intelligence, and that's just the reality of how life is.

    However, to succeed in life, one first needs to set a goal and then gradually make it more practical. And, in addition to that, in order to get really good at something, one needs to spend at least 10,000 hours studying and practicing. To become great at certain things, it'll require even more time, time that most people won't put in.

    This is a big reason why many successful people advise you to do something you love. If you don't enjoy what you do, it is going to feel like unbearable pain and will likely make you quit well before you ever become good at it.

    When you see people exhibiting some great skills or having achieved great success, you know that they have put in a huge part of their life to get there at a huge cost. It's sometimes easy to think they got lucky or they were born with some rare talent, but thinking that way does you no good, and there's a huge chance that you're wrong anyway.

    Whatever you do, if you want to become great at it, you need to work day in and day out, almost to the point of addiction, and over a long period of time. If you're not willing to put in the time and work, don't expect to receive any rewards. Consistent, hard work won't guarantee you the level of success you may want, but it will guarantee that you will become really good at whatever it is you put all that work into.

    Scotland has long been characterized as a land of romance. It contains ruins of many ancient castles and abbeys，and there is an attractive beauty in its mountains，long deep valleys，and ribbon lakes. Each year those things attract a great number of tourists.

    Numerous islands line the coast. In the north are two large groups，the Orkney Islands and the Shetland Islands. Close to the west coast are the Inner and Outer Hebrides groups，and the islands of Arran and Bute.

    The land may be divided into three regions: the Highlands in the north，the Central Lowlands and the Southern Uplands.

    The Highlands are wild and picturesque(如画的). A long valley called Glenmore crosses the Highlands from southwest to northeast.

    In the south of the Highlands are the Grampian Mountains，highest in the British Isles. Ben Nevis，the highest peak，rises to 1，243 meters. Ben Lomond rises from the shore of Loch Lomond，Scotland's largest freshwater lake.

    The Central Lowlands run from southwest to northeast and the greatest length is nearly 145 kilometers. The soil here is fertile，and there are four coalfields underlying the area. In the east is Edinburgh，Scotland's historic capital city，and in the west is Glasgow. Almost 90 percent of Scotland's population live in the Lowlands.

    In the Southern Uplands，the hills are generally less than 600 meters high. Their rounded or flat tops are often capped with dark peat(泥炭). Along the slopes are plants like grass and heather(石南花).

    According to new research from the University of Cambridge in England, sheep are able to recognize human faces from photographs.

    The farm animals, who are social and have large brains, were previously known to be able to recognize one another, as well as familiar humans. However, their ability to recognize human faces from photos alone is novel.

    The recent study, the results of which were published in the journal Royal Society: Open Science. Show the woolly creatures could be trained to recognize still images of human faces, including those of former President Barack Obama and actress Emma Watson.

    Initially, the sheep were trained to approach certain images by being given food rewards. Later, they were able to recognize the image for which they had been rewarded. The sheep could even recognize images of faces shown at an angle, though their ability to do so declined by about 15 percent – the same rate at which a human's ability to perform the same task declines.

    "Anyone who has spent time working with sheep will know that they are intelligent, individual animals who are able to recognize their handlers," said Professor Jenny Morton, who led the Cambridge study. "We've shown with our study that sheep have advanced face-recognition abilities, comparable with those of humans and monkeys."

    Recognizing faces is one of the most important social skills for human being, and some disorders of the brain, including Huntington's disease, affect this ability.

    "Sheep are long-lived and have brains that are similar in size and complexity to those of some monkeys. That means they can be useful models to help us understand disorders of the brain, such as Huntington's disease, that develop over a long time and affect cognitive abilities. Our study gives us another way to monitor how these abilities change," Morton said.

    There is more of a connection between food and culture than you may think. On an individual level, we grow up eating the food of our culture. It becomes a part of who we are. Many associate food from our childhood with warm feelings and good memories and it ties us to our families, holding a special and personal value for us. Food from our family often becomes the comfort food we seek as adults in times of frustration and stress.

    On a large scale, traditional food is an important part of culture. It also operates as an expression of culture identity. Immigrants bring it wherever they go, and it is a symbol of pride for their culture and means of coping with homesickness.

    Many immigrants open their own restaurants and serve traditional dishes. However, the food does not remain exactly the same. Some materials needed to make traditional dishes may not be readily available, so the taste and flavor can be different from what they would prepare in their home countries. Additionally, immigrants do not only sell dishes to people from the same countries as them, but to people from different countries. Therefore, they have to make small changes about the original dishes to cater to a wider range of customers. Those changes can create new flavors that still keep the cultural significance of the dishes.

    We should embrace our heritage（传统）through our culture's food but also become more informed about other cultures by trying their food. It is important to remember that each dish has a special place in the culture to which it belongs, and is special to those who prepare it. Food is a window into culture, and it should be treated as such.
