Wild weather, unexpected coral reefs and dangerous sea creatures… these are the nightmares (噩梦) you can imagine a teenager on a solo voyage (独自旅行) around the world might suffer from. But for Laura Dekker, sailing around the globe seems less a price to be paidthan a prize to be treasured.

    As the 19-year-old Dutch sailor said in Maidentrip, a documentary（纪录影片） released last year about her experience of becoming the youngest person to sail around the world alone in 2012, “I was born on a boat. I lived my first five years at sea. And ever since, all I have wanted is to return to that life.”

    With her yacht(游艇) Guppy, Dekker began her journey at 14 and sailed 50,004 kilometers in 519 days.

    The flying fish keeping her company, the dolphins following in her wake and the warm days spent on deck playing the flute (长笛) as she watched another unforgettable sunset were enough to make others jealous.

    But these didn't always go well. There were terrible moments in which Dekker feared death. On one occasion, a whale almost turned Guppy over. Another time, she battled extreme winds and Guppy surfed down 8-meter-high waves.

    Out on the open sea alone, she also got used to living without a fridge, a flushing（用水冲洗） toilet, and a hot shower.

   “As a human being you don't need much,”she told Stuff.co.nz. “ They might make life more comfortable, but you really don't need them to be happy.”

    In fact, her outlook on life was shaped by the trip. “I wanted the storms. I wanted the calms. I wanted to feel loneliness,”she told The New York Times. “And now I know all these things. It's the end ofthe dream I had as a child, and it's the beginning of my life as a sailor.”

    Since 2004, Australia has been holding its largest study of children's health ever. This project, “Growing Up in Australia,” is following two groups of children from early childhood until they become adults. The project is being supported by the Australian government and involves hundreds of researchers visiting the homes of 10,000 children. Researchers hope to find a relationship between the children's future behavior and their health, education, and family environments.

    When the study began, the first group of children was aged 0-1, while the second group was aged 4-5. In order to make sure that children from every kind of environment and background were chosen, the study found volunteers from each area. Some volunteers are in the countryside, while others are in big cities. The volunteers for both groups were chosen from a variety of different social and ethnic (种族) backgrounds.

    The researchers visit the participants' (参与者) homes every two years to gather information. They interview the parents about parenting styles and the child's daily activities. They also take measurements of the children's health and how well the children perform in school. The researchers also collect information such as the income of the child's family, the school the child attends, and the kind of community (社区) in which the child lives. They plan to use the information to improve children's lives.

    Researchers have already begun to publish some interesting results. For instance, after examining information from the second group of children when they were 10-11 years old, researchers found that children who spend a lot of time doing organized activities, such as music lessons or sports, have good control of their emotions and behavior. The study also found that they are able to complete their homework without their parents around. On the other hand, it found that children who watch a lot of television get upset easily and have worse behavior. The Australian government is now using this information to make better educational and health policies for Australian children.

    In many countries, authority is seldom questioned, either because it is highly respected, or because it is feared. Because rank has been important in certain societies for a long time, people have been trained never to question those in authority. For example, children are not expected to question their teachers in school. It may be considered improper for young businessmen to suggest ideas that differ from those of older, more experienced members of the business.

    In other countries, including America, children are trained to question and search for answers. When a child asks a question, he will often be told to go to the library and find the answer for himself. By the time students reach the age of 14 or 15, they may be developing exciting new ideas in all fields of science and arts. To encourage such creativity, there are many national prizes offered to students every year for their scientific discoveries and artistic accomplishments.

    This interest in questioning and searching may be considered by some people as bad for young people's manners, that young people lack respect for authority. This impression may be created when visitors notice young Americans asking questions and arguing with older people. However, this is because many Americans have a different attitude toward authority than may exist in other areas of the world. In a work or business situation, ideas are freely and openly discussed and argued. It is important to remember that it is the person's ideas that are being questioned, not the individual himself. The two are quite separate. The purpose of the searching, questioning, and arguing is to find the facts in a particular situation, and therefore a solution, so that the work of the business can progress in the most effective manner possible.

    As was mentioned earlier, you may notice the same questioning in social conversations. Although some individual may think that Americans are rude because of the direct manner with people, they are merely trying to learn more about your ideas.

    Most of us will be familiar with the traditional talent show set-up: thousands of hopefuls line up outside the audition（试音）room, wait for hours to go in and perform for a group of judges. Then these potential pop stars could be lucky and get through to the next round, or they might hear the command, "Sorry, it's a no from me. But what do the judges actually bring to a talent show?

    Music talent show judges attract millions of viewers each week to their programs. As public figures, they play an important part in advertising campaigns for these programs. They often receive high salaries and can be moody. Are they really worth the expenses and difficulties that they cause? One solution might be to replace them with computers.

    Can computers really match human judges? Scientist Dr Nick Collins and his team at the University of Sussex think they can. Dr Collins has been working on a project that involves programming three computerized judges that he says would be far more consistent in their judgment of musical performances. Employing a special programming language, Dr Collins's digital judges can be trained up by "listening" to particular musical styles. After they have been listening for a while, the programming language allows these judges to spot the specific features of the music, including the voice quality, the rhythm etc. Collins says, “The judges' listening capacity is not yet as good as a human ear, but they won't be as moody as some human reality TV show judges.”

    Maybe that is the problem with this electronic musical innovation. Real human judges on talent shows interest us with their personality, decisions and catchy phrases. Will a computer program be able to do the same?
