How is it that siblings (兄弟姐妹) can turn out so differently? One answer is that in fact each sibling grows up in a different family. The firstborn is, for a while, an only child, and therefore has a completely different experience of the parents than those born later. The next child is, for a while, the youngest, until the situation is changed by a new arrival. The mother and father themselves are changing and growing up too. One sibling might live in a stable and close family in the first few years; another might be raised in a family crisis, with a disappointed mother or an angry father.

    Sibling competition was identified as an important shaping force as early as in 1918. But more recently, researchers have found many ways in which brothers and sisters are a lasting force in each others' lives. Dr. Annette Henderson says firstborn children pick up vocabulary more quickly than their siblings. The reason for this might be that the later children aren't getting the same one-on-one time with parents. But that doesn't mean that the younger children have problems with language development. Later-borns don't enjoy that much talking time with parents, but instead they harvest lessons from bigger brothers and sisters, learning entire phrases and getting an understanding of social concepts such as the difference between “I” and “me”.

    A Cambridge University study of 140 children found that siblings created a rich world of play that helped them grow socially. Love-hate relationships were common among the children. Even those siblings who fought the most had just as much positive communication as the other sibling pairs.

    One way children seek more attention from parents is by making themselves different from their siblings, particularly if they are close in age. Researchers have found that the first two children in a family are typically more different from each other than the second and third. Girls with brothers show their differences to a maximum degree by being more feminine than girls with sisters. A 2003 research paper studied adolescents from 185 families over two years, finding that those who changed to make themselves different from their siblings were successful in increasing the amount of warmth they gained from their parents.

    It happened to me recently. I was telling someone how much I had enjoyed reading Barack Obama's Dreams From My Father and how it had changed my views of our President. A friend I was talking to agree with me that it was, in his words ,“a brilliantly written book” However, he then went on to talk about Mr. Obama in a way which suggested he had no idea of his background at all. I sensed that I was talking to a book liar.

    And it seems that my friend is not the only one. Approximately two thirds of people have lied about reading a book which they haven't. In the World Book Day's “Report on Guilty Secrets”, Dreams From My Father is at number 9. The report lists ten books, and various authors, which people have lied about reading, and as I'm not one to lie too often (I'd hate to be caught out), I will admit here and now that I haven't read the entire top ten. But I'm pleased to say that, unlike 42 percent of people, I have read the book at number one, Gorge Orwell's 1984. I think it's really brilliant.

    The World Book Day report also has some other interesting information in it. It says that many people lie about having read Jane Austin Austen, Charles Dickens, Fyodor Dostoevsky (I haven't read him, but haven't lied about it either) and Herman Melville.

    Asked why they lied, the most common reason was to “impress” someone they are speaking to. This could be tricky if the conversation became more in-depth!

    But when asked which authors they actually enjoy, people named J.K. Rowling, John Grisham, Sophie Kinsella (ah, the big sellers, in other words). Forty-two percent of people asked admitted they turned to the back of the book to read the end before finishing this story (I will come clean: I do this and am astonished that 58 percent said they had never done so.).

    A 525-year-old copy of a letter by Christopher Columbus, stolen from the Vatican, was returned this week. An investigation by the United States Department of Homeland Security and the Vatican located the letter.

    “We are returning it to its rightful owner, “said U.S. ambassador to the Vatican, Callista Gingrich, at a ceremony in the Vatican Library. Columbus wrote the letter to the king and queen of Spain after discovering “The New World.” He described what he had found and requested money for another trip. His original letter was written in Spanish. But several copies of a Latin translation were made to spread news of his discovery to the royal courts of Europe and the Pope.

    One of the Latin letters, copied by Stephan Plannack in 1493, was put in the Vatican Library. Known as the Columbus Letter, it has eight pages, each about 18.5 cm by 12 cm. In 2011, an American expert in rare manuscripts received a similar looking letter. After reviewing it, he decided that it was real. The year before, the same expert had studied a Columbus Letter in the Vatican Library and suspected that it was a fake. One reason was that the stitching (针脚) marks on the letter were not the same as those on the cover. The letter in the United States, however, had the exact same stitching marks as the leather cover of the fake letter he had studied in the Vatican.

    The expert, who was not identified, contacted Homeland Security art investigators, who began working with Vatican inspectors and rare book experts. They believed that someone took the real letter out of its cover at the Vatican Library and replaced it with an artificial one. Archbishop Jean-Louis Brugues is the Vatican's chief librarian. He said, “We do not know exactly when the substitution took place. We will probably never know who the forger (伪造者) was.”

    Their investigations found that Marino Massimo De Caro, a well-known Italian book thief, had sold the real letter to a New York book dealer. De Caro is serving a seven-year prison sentence in Italy for stealing about 4,000 ancient books and manuscripts from Italian libraries and private collections. The late collector David Parsons bought the letter for $875,000 in 2004. After the investigations, his widow agreed to return the letter to the Vatican Library. Officials said the letter is now worth about $1.2 million.

    In 1971, UN scholar Paolo Lugari started an eco-social experiment in Gaviotas, Colombia. Located in one of the most extreme climates, Gaviotas was described as a sustainable, self-sufficient village in an area that Lugari called 'just a big, wet desert'.

    'They always put social experiments in the easiest places,' Lugari said.'We wanted the hardest place. We figured if we could do it here, we could do it anywhere.'

    'Lugari just thought that someday the world would become so crowded that humans would have to learn to live in the planet's least desirable areas,' wrote Alan Weisman, author of Gaviotas: A Village to Reinvent the World.

    Today, Gaviotas is an eco-village with about 200 people. They farm organically. They use wind and solar power. Since 2004, Gaviotas has been 100% fossil fuel independent. The residents also enjoy free housing, schooling, and community meals. Shockingly, there are no weapons, no police, no jail and no mayor. But though these elements would make any social experiment a success, perhaps the most remarkable accomplishment is the planting of 1.5 million pine trees and palm trees. The various results of this new tree growth have been incredible. The shade of the trees has inspired the return of many rainforest species that were once native to the region. Additionally, the residents of Gaviotas enjoy a sustainable source of income from the resin(松香) harvested from the trees.

    The United Nations named Gaviotas a model of sustainable development. The Colombia novelist and Noble Prize winner Grabriel Marquez called Lugari the 'inventor of the world'.

    A new study by a team of researchers has found that 'nature's capacity to store carbon is steadily falling as the world's farmers expand croplands at the cost of the native ecosystem such as forests'.

    Considering this disturbing fact—and as the world population increases towards an estimated 9 billion by the year 2050 and global warming continues to increase the planet's surface temperature—Gaviotas stands as one shining example of how things could be different.

    Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter (住所) as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pets in danger of serious illness. There are things you can do to keep your animal warm and safe.

    Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you're cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.

    If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet's water. Sometimes owners don't realize that a water bowl has frozen and their pet can't get anything to drink. Animals that don't have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.
