While it's wonderful to share a special trip with friends or family, traveling alone is another experience. {#blank#}1{#/blank#}

1）. Meet new people.

    People who are traveling alone seem more approachable to others. Before you know it, you could be chatting with some interesting folks at a sidewalk cafe or even joining a group of like-minded people on the beach. {#blank#}2{#/blank#}

2）.Do everything you want and nothing you don't want.

    Have you ever been hesitant to do that half-day at the spa you are eager for because you feel bad leaving your travel partner with nothing to do? {#blank#}3{#/blank#} If you want to “waste” the day sitting at an outdoor bar drinking a cocktail instead of sightseeing, you won't have to answer anyone.

3）.{#blank#}4{#/blank#}

    If traveling makes you a good, smart person, then traveling alone makes you better and smarter. Taking a trip by yourself might seem frightening. However, once you take the courage and get over your fears, you'll feel a sense of energy. A successful single vacation can inspire you to try new things in life.

    Five meteorologists (气象学家) who were trapped for two weeks after polar bears surrounded their weather station are now able to leave after the creatures were chased away. Their supervisor told NBC News early Wednesday.

    Russian officials had feared the siege could last for another month, the time it would take to reach the islands in the Kara Sea, high in the Arctic Circle. But on Tuesday night a research ship took a detour (绕道) to assist those weathermen, station supervisor Vasily Shevchenko told NBC News. The ship run by Russia's state-run oil firm Rosneft frightened away the bears using its helicopter, before resupplying the weather station with more food and puppies (幼犬) . The puppies are not yet big enough to deter the bears, but the station is planning to draft in a replacement adult guard dog as soon as possible.

    Some of the bears had taken to sleeping directly outside the windows of remote outpost. There was no risk of the researchers starving because they had a year's worth of food, but they were forced to take dangerous trips to a nearby building, holding a gun for protection, according to Shevchenko.

    Polar bears are an endangered species. In Russia, it's a crime to shoot them unless in self-defense. The bears usually leave the islands in the summer, but this time they were trapped by the melting ice, an apparent sign of climate change, according to Shevchenko. “They've stayed on the island because there is nowhere for them to go,” he said.

    The animals suffer from global warming because it shrinks the floating ice that forms their main hunting ground. According to the environmental group the World Wide Fund for Nature, known as the WWF, this has got some polar bears to go near human habitats in search of food.

    The light from the campfire brightened the darkness, but it could not prevent the damp cold of Dennis's Swamp (沼泽地) creeping into their bones. It was a strange place. Martin and Tom wished that they had not accepted Jack's dare. They liked camping, but not near this swamp.

    "So," Martin asked as they sat watching the hot coals. "How did this place get its name?"

    "Are you sure you want to hear it? It's a scary story," warned Jack.

    "Of course!" cried out Tom. "If there were anything to be scared of, you wouldn't have chosen this place!"

    "Ok, but don't say I didn't warn you," said Jack, and he began this tale.

    "Way back in time, a man called Dennis tried to start a farm here. He built that cottage over there to live in. In those days, the area looked quite different—it was covered with tall trees and the swamp was a crystal-clear river. After three hard years, Dennis had cleared several fields and planted crops. He was so proud of his success that he refused to listen to advice.

    "'You are clearing too much land,' warned one old man. 'The land is a living thing. It will hit back at you if you abuse it. '"

    "'Silly fool,' said Dennis to himself. 'If I clear more land, I can grow more crops. I'll become wealthier. He's just jealous!'"

    "Dennis continued to chop down trees. Small animals that relied on them for food and shelter were destroyed. He was so eager to expand his farm that he did not notice the river flowing slowly towards his door. He did not notice salt seeping to the surface of the land. He did not notice swamp plants choking all the native plants."

    "What happened?" Martin asked. It was growing colder. He trembled, twisting his body closer to the fire.

    "The land hit back—just as the old man warned," Jack shrugged. "Dennis disappeared. Old folks around here believe that swamp plants moved up from the river and dragged him underwater. His body was never found."

    "What a stupid story," laughed Tom. "Plants can't …" Before he had finished speaking, he screamed and fainted (晕倒). The other two boys jumped up with fright, staring at Tom. Suddenly, they burst out laughing. Some green swamp ivy (常春藤) had covered Tom's face. It was a while before Tom could appreciate the joke.

    Car washes are a common sight throughout Nigeria, but Madinat Aliyu's roadside business is very special: she is the only woman car-washer in the north of the country.

    "This job has caused me a lot of problems," said the 27-year-old, checking cars waiting to be cleaned in Gusau, the capital of Zamfara state.

    Aliyu took up her work two years ago, hoping to use the 7, 000 naira (£28) she earned every month to put her younger sisters and brothers through school following the death of their mother, the only one who made money to support the family. But her family begged her to stop doing this job, and she has received "judgment and warnings" from strangers too.

    "My grandmother cried for many days. Some people thought it was a joke to bring more customers (顾客). Others said if she is doing it for money, let's just give her money to stop bringing us shame," she said as she got water from a well by the roadside. "But I hate laziness or depending on somebody else."

    However, Aliyu has admirers. "Some customers only allow her to wash their cars," said her colleague (同事) Shamsudeen Mohammed. "I was trained to wash cars by men, and I can honestly tell you women are better to work under," he added.

    Recently another woman came to Aliyu to ask for advice on starting her own car wash. "Unfortunately her family discouraged her. I told her, if you listen to them, you will find yourself begging or marrying a man who is older than your grandfather," she said.

    Though she is considered a pariah (贱民) by many, Aliyu has no plans to stop her work. "I see men doing something and I think I can do it too."

    Most Americans see their pets as family members, surveys show. Those with dogs are more likely to call themselves pet "parents" than pet "owners". There are more of these parents than ever. In big cities such as San Francisco and Seattle,(owned) dogs outnumber children.

    The ways in which companies are profiting from the trend are also becoming various. Kinds of dog food and various pet mattresses (垫子) are always in hot sale. And it is not surprising that, for pets, Americans spent more than $400 million only on Halloween costumes this year. Overall, annual spending on pet food and products in America has risen by around 40% over the past ten years.

    Now a pack of startups have sensed a fresh opportunity.

    Much as Airbnb has offered travelers another choice instead of staying in a hotel, two firms, Recover and DogVacay, want to give pet owners an alternative to kennels (养狗场) when away from home. The cost is around $30 a night, with the majority of that going to the sitter, who takes care of the dog, and around a fifth to the company﹣much less than you would spend to check your dog into a kennel.

    The other big sellingpoint is that pets will receive better treatment. There are ways, apparently, to vet (审查) dog hosts to the real pet lovers: only around 15% of those who apply to serve as sitters are passed. Besides offering more attention and room, Rover has launched a feature that helps customers to see how far their dog has been walked via the GPS in the host's phone. Like Airbnb, both DogVacay and Recover insure stays against accidents.

    Another advantage of the model is that consumers often use dog-sitting services many times a year, and they tend to be loyal. That has helped DogVacay and Recover attract a lot of money﹣around $140 million between them.

    But firms that connect pets with hosts will face great competition as they try to go global. Companies offering homestays for dog rapidly appear in many different countries, including Australia, Brazil and Britain. And unlike Airbnb, which pulls in customers thanks to its presence in lots of markets that people want to travel to, the network effect for services like DogVacay is local.

    Despite having predicted the trend early, such firms may never achieve the same scale as an Airbnb. But then no one ever said it was easy to be top dog.
