As one of the world's oldest holidays, Halloween is still celebrated today in several countries around the globe, but it is in North America and Canada that it maintains its highest level of popularity. Every year, 65% of Americans decorate their homes and offices for Halloween. Halloween is the holiday when the most candy is sold and is second only to Christians in terms of total sales.

Austria

    In Austria, some people will leave bread, water and a lighted lamp on the table before retiring on Halloween night. The reason for this is that it was once believed such items would welcome the dead souls back to earth on a night which for the Austrians was considered to be brimming(溢)with strong cosmic energies.

Belgium

    The Belgians believe that it is unlucky for a black cat to cross one's path and also unlucky if it should enter a home or travel on a ship. The custom in Belgium on Halloween night is to light candles in memory of dead relatives.

Canada

    Modern Halloween celebrations in Canada began with the arrival of Scottish and Irish immigrants in the 1800s. Jack- O- Lantern is carved and the festivities include parties, trick-or-treating and the decorating of homes with pumpkins and corn stalks.

France

    Unlike most nation of the world, Halloween is not celebrated by the French in order to honor the dead and departed ancestors. It is regarded as an “American” holiday in France and was unknown in the country until around 1996.

Yellowstone Weather

    Yellowstone National Park is at lofty height. Height. Most of the park is above2,275meters.

    Yellowstone's weather is unpredictable. In summer, it may be warm and sunny with temperatures in the high 70s. At night in any given month, the temperature may drop close to freezing. So it is best to come prepared for cold evenings and mornings,especially if you are camping or hiking. When you leave your campsite,please leave it prepared for possible thundershower and wind.

A sunny warm day may become fiercely stormy with wind, rain, sleet and sometimes snow. Without enough clothing, an easy day hike or boat trip can turn into a battle for survival.

    Having a learning disability doesn't mean you can't learn, but you'll need some help and need to work extra hard. If you have a learning disability such as dyslexia or dyscalculia, remember that you are not slow or stupid.

    Learning disabilities can be genetic. That means they can be passed down in families through the genes. But kids today have an advantage over their parents. Learning experts now know a lot more about the brain and how learning works, and it's easier for kids to get the help they need.

    Dyslexia is a learning disability that means a kid has a lot of trouble reading and writing. Kids who have trouble with math may have dyscalculia. Other kids may have language disorders, meaning they have trouble understanding language and understanding what they read.

    It can be confusing, though. What qualifies as “trouble" enough to be diagnosed as a learning disability? Reading, doing math, and writing letters may be tough for lots of kids at first. But when those troubles don't fade away and it's really difficult to make any progress, it's possible that the kid has a learning disability.

    Finding out you have a learning disability can be upsetting. You might feel different from everyone else. But the truth is that learning disabilities are pretty common. And if your learning specialist or psychologist has figured out which one you're facing, you're on the right track. Now, you can start getting the help you need to do better in school.

    But for this special help to really work, you'll need to practice the new skills you're learning. It may take a lot of efforts every day. That can be a challenge, but you can do it soon, you'll enjoy the results of all your hard work: more fun and success at school.

    Cold weather during winter months may keep many people from leaving home and running in the open air.

    However, a new study shows that the drop in temperature is a good reason to run. In fact, researchers say, running in cold weather helps improve one's performance.

    Many people say running in the winter can be difficult. Two reasons are the low temperatures and bitter winds. Yet many runners might find it easier than running in hot weather.

    That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate and the body's dehydration (脱水) levels are lower than in warmer conditions. The body needs less water on a cold day than in warm weather.

    This information comes from sports scientists at St. Mary's University in London. John Brewer is a professor of applied sport science at St. Mary's.

    For this study, he and other researchers put a group of people into a room they called an “environmental chamber.” The researchers then recreated summer and winter weather conditions in the room. The test subjects were asked to run 10,000 meters under both conditions. Brewer says he and his team recorded biological measurements of the runners.

    “We've got a group of subjects into the environmental chamber, we've changed the conditions to replicate the summer or winter and we've got them to run a 10km under both of those conditions and taken various measurements on each runner while they've been completing their 10km.”

    Brewer says every movement runners make produces heat. He explains that one way in which we lose heat is by sweating. The body loses heat through droplets of sweat. He says the body also loses heat by transporting the blood to the surface of the skin.

    Procter & Gamble (P&G), one of the world's biggest marketers, has announced a change in the way it buys advertising on Facebook. It has started cutting its spend on highly targeted ads and increasing its spend on ads that address much larger numbers of the potential audiences for its brands, which include Tide, Pampers and Gillette. Explaining this change of emphasis, P&G's global brand building officer, Marc Pritchard, said, "We targeted too much, and went too narrow."

    Facebook's astonishing income growth comes, in part, from its ability to deliver micro-targeted audiences (推送精准目标受众) to advertisers, and P&G in fact admits that it has wasted millions of dollars in the misguided pursuit of effectiveness.

    Facebook used to be irresistible to advertisers. It presents advertisers this question: Instead of sending your message to millions in a television ad, why not use data to reach only those you need to reach? But as many people may have noticed, making perfectly targeted ads appears to be much harder than it sounds. Most digital ads are easily ignored. Information about consumers is not the same as insight into human beings.

    The more fundamental problem with micro-targeting is that for big brands, advertising has never really been about messages—even brand owners have never quite realized it. It is about the creation of shared memories, triggered at the point of purchase. Think about some of the great brands: Nike, Apple, and yes, Pampers. If you buy them, it is because you know millions of others do, and because they seem to stand for something that, far from being unique to you, is common to all of us: achievement, creativity, and nurturing. The broader these brands go, the better they do.

    When a consumer reaches for something on the shelf, they usually reach for the familiar. To achieve that status, a brand needs to have done something that lots of people regularly see, notice and enjoy. What seemed to be the wastefulness of TV was in fact its secret sauce. By reaching large numbers of people at the same time, TV ads had the power to turn brands into cultural icons, which took up consumers' minds.

    In its conversations with advertisers, Facebook now talks less about targeting, preferring to emphasize the large number of consumers that it can help brands to reach. It is investing in video functions and is encouraging its clients to make short films. After years of telling clients TV is wasteful, it is now doing a good job of imitating it.

A Dream Chaser in a Wheelchair

    Since the age of three, Chelsie Hill had dreamed of becoming a dancer. That ambition nearly ended in 2010 when Hill was in a car accident, which put the 17- year-old high school senior in hospital for 51 days and left her paralyzed from the waist down. For most people, that would have destroyed any hope of a dancing career. But for Hill, it was the beginning. Far from being a barrier, her wheelchair encouraged her to fight. "I want to prove to everyone including myself that I'm still normal," she said, "whatever normal means."

    Normal for her meant dancing, so Hill did it in her wheelchair alongside her nondisabled high school dance team. Half of her body was taken away from her, so she had to move it with her hands. It took much learning and patience.

    After graduation from high school, Hill wanted to expand her dance network to include women like her. She met people online who were fighting for the dream of dancing against various spinal(脊椎的)injuries, and invited them to dance with her. To reach more people in a larger city, Hill moved to Los Angeles in 2014 and formed a team of dancers with disabilities she called the Rollettes.

    Every year Hill holds a dance camp called the Rollettes Experience for wheelchair users to help them bring out their acting talent. In 2019, 173 participants from ten countries attended. For many, it was the first time they'd felt they belonged. Edna Serrano said that being part of the Rollettes team gave her the courage to get behind the wheel of a car. "I didn't know I could do so many things that my fellow teammates had taught me." she said. "I didn't know I could be sexy. It's so powerful to have my teammates in my life, because they're my teachers. I have more confidence."

    Chelsie Hill attained what many of us never will: her childhood dream. She has been chasing her dream in the wheelchair. She's a dancer. The Rollettes have helped her find something else just as fulfilling.
