In 1858, two men wanted to be elected United States Senator from Illinois. One was Stephen Douglas. The other was Abraham Lincoln. Douglas was already the Senator, but his term in office was up. Lincoln had once been a U.S. Representative but was then a lawyer in Illinois.

    The men agreed to have seven public meetings, or debates, in seven different cities in Illinois. That way, voters all over the state would have a chance to hear what each man stood for.

    The first debate was in Ottawa on August 21, 1858. The main thing the men disagreed on was slavery. Douglas believed that as new states joined the union, they should decide for themselves whether or not they wanted to be a slave state or a free state. Lincoln believed that slavery should not spread beyond the states that already had slaves. He said the United States could not survive as half-slave and half-free states.

    The debates drew large crowds in all seven cities. People in the entire country were paying attention. Lincoln lost the Senate race. The debates did, however, make him well known everywhere.

    In 1860, it was time to elect a new President. Lincoln won the Republican party's nomination(提名). Douglas won the Democratic party's nomination. The two men again faced each other to get the people's votes. This time Lincoln won. He became the nation's 16th President.

    The slavery issue was still causing bad feelings between slave and non-slave states. By the time Lincoln took over as President on March 4, 1861, seven states had left the union. A month later, the Civil War began.

    “Children start putting their fingers in their noses as infants,” says Sarah Springer, MD' of Kids Plus Pediatrics in Pittsburgh. “As soon as they have motor control of their fingers, they'll find holes where their fingers can fit. It's not a worry—just a normal part of how they explore and learn.”

    In order to help your child to stop engaging in the behavior it's important to understand why they may start the habit in the first place, according to the University of Michigan Health System. Nose-picking can be a result of boredom, sleepiness, falling asleep, relaxation or coping. In most instances, nose-picking is likely just a phase（阶段）and the child will eventually quit it.

    There isn't much parents can do to stop the behavior of nose-picking, as it's a normal part of being a kid, Dr. Springer says. Parents are advised to ignore the behavior and not show frustration's this won't help encourage your child to stop picking their nose. Instead, Dr. Springer says to help your child learn to blow their nose once they are four or five years old and talk to your child about keeping their hands clean to avoid spreading germs.

    Take note of the season or climate, too, as dry air or cold can increase the occurrence of nose-picking. Parents should use a humidifier（增湿器）in these conditions to help nasal secretions（鼻分泌物）stay moist. Putting petroleum jelly（凡士林）a few times a day inside the nose can help with irritation and minimize picking.

    Once your child enters school, it's inevitable for them to see and pick up bad habits, Dr. Springer said. Nose-picking is a common habit, even among adults and as children age most will realize it's not an acceptable behavior.

    “Nose picking is a normal part of childhood,” Dr. Springer says. “Most kids will become conscious of the social stigma（羞耻）associated with it, and will eventually stop picking, at least in public.”

    Making friends is a skill like many other skills. It improves with practice. If you want to meet people and make friends，you must be willing to take some actions. You must first go where there are people. You won't make friends staying home alone. Join a club or a group. Talking with those who like the same things as you do is much easier. Or join someone in some activities. Many people are nervous when talking to new people. After all meeting strangers means facing the unknown. And it's human nature to feel a bit uncomfortable about the unknown. Most of our fears about dealing with new people come from doubts about ourselves. We imagine other people are judging us or finding us too tall or too short，too this or too that. But don't forget that they must be feeling the same way. Try to accept yourself as you are and try to put the other person at ease. You'll both feel more comfortable.

    Try to act self­confidently even if you don't feel that way. When you enter a room full of strangers，such as a new classroom，walk tall and straight，look directly at other people and smile.

    If you see someone you'd like to speak to，say something. Don't wait for the other person to start a conversation.

    Just meeting someone new does not mean that you will make friends with that  person—friendship is based on mutual liking and“give and take”. It takes time and effort to develop.

    The Spanish sculptor Isaac Cordal sees the city as his playground. He specializes in miniature, a street art often representing a social commentary as a critical observation on capitalism, power and so on.

    Cordal first models the sculptures in clay then reproduces them in cement(水泥)about 15cm in height.

    “As a material, cement seems very symbolic because it is one of our most recognizable footprints against nature.” he says. “Today we have been too used to cement city habitat.”

    For several years he's been working on the project, Cement Eclipses, referring to the state when a building covers the sun: “It's a critical reflection on the idea of progress.”

    These tiny cement figures have appeared in cities across Europe, found sitting on top of bus shelters or drowning in the grass land of the big city. “The street became a perfect setting in which I could find enough landscapes for them. Due to their small size and color, they go really well into the urban environment. They even normally go unseen by passersby. I'm very interested in that moment of surprise when someone accidentally discovers them.” he says.

    “Nowadays there is a fear of not being seen in the public area, so everything is always big and bold. We become a product of this and do not focus in as much. I think it is good to pay attention to small details. My work is a reward for those who do and it allows us to understand and change the world we have created in a different angle.”Cordal says.

    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.

Sea, Sun, Sand and South Africa: Readers' Favorite Beaches

    The Wild Coast five-day hike from Kei Mouth to Coffee Bay in South Africa is surely the best experience for beach lovers.

    Robben Island beaches

    On a visit to the prison museum here, be sure to leave time to explore the island's beaches. Few visitors realize that the island's shores are the natural habitat of sizable penguins: enjoy watching them with far fewer tourists here. Bird life is plentiful and includes oystercatchers, ibis, egrets and cormorants. Sharks and dolphins can often be spotted offshore too.

    Sand, sea and sculpture, Durban

    There's more to Durban's Golden Mile than sunbathing and surfing. Not only is there a gallery of sand sculptures(雕像) and drawings, but Lucas, one of the best local artists, offers lessons. His amazing rhino(犀牛) is the only permanent item in a frequently changing exhibition. Lucas charges a modest R50 (£3) for a fun and surprisingly physical hour of creativity. Or, you could ask him to create a personalized sculpture for a special occasion.

    Paternoster, Western Cape

    Paternoster is a small beach community about 150 km north of Cape Town. The town has a number of rentals(租赁), all the Cape Dutch architecture you could want for a weekend away and some great food. Long walks on the beach, eating and drinking and watching the fishing boats make for a peaceful break. And, unlike in Cape Town, you can dip your toes in the sea without your legs freezing solid.
