To American visitors, Iceland is a very interesting country, partly because it is different in so many ways from he or she is used to seeing at home. There are quite a few things that are not done, or that do not exist on the island—quite a few “No's”．

    There is no pollution, for instance, no dogs are permitted in Reykjavik, the capital. There is no television on Thursdays or during the whole month of July, and only three hours of black­and­-white TV the rest of the time. There is no hard liquor（酒） on Wednesdays and no beer at any time. There is no handguns; only one prison of thirty­ five rooms in the whole land—an admirable figure, even for a small country of 313,376 people.

    There is no army, air force or navy. There is no tipping（给小费） for anything. There are no large stores open on Saturdays or Sundays. Since Iceland is located just under the Arctic Circle, there is no darkness in summer and no daylight in winter. But thanks to Gulf Stream, the climate is rather mild, with temperatures between 34 degrees and 52 degrees in July.

    The rules on television liquor and guns are the result of government decisions. But the absence of pollution is because of in great part the fact that Iceland gets its power from the thousands of hot springs(泉水) that come out of the ground. They provide all the energy needed by the country. In fact, Iceland uses only 3 percent of all its available power.

    Iceland has been described as a democratic（民主的） independent country where more fish are caught and more books published per person than anywhere else in the world. The Icelanders have always felt a particular love for literature. They wrote their first books in the ninth and tenth centuries AD. These works were poems and tales about the kings, heroes, and heroines of Iceland and Norway. At first, the stories were remembered and passed from generation to generation. They were finally written down between 1140 and 1220. The Icelanders have never stopped writing ever since. “Rather shoeless than bookless，” they proudly say.

    It was a warm April day when a big fat envelope came in the mail from the only college I had ever imagined attending. I tore open the packet. My eyes were fixed on the word “congratulations”. I don't remember ever smiling so wide.

    Then I looked at my financial(财政的) package.

    The cost of Dream School's tuition(学费), room and board was around ＄40,000 ? An impossible sum! How could I afford to attend? What good reasons did I have to go there when three other fine colleges were offering me free tuition? My other choices were good, solid schools even if they weren't as famous as my first choice.

    In my mind, attending my dream university would be the only way to realize my dream of becoming a world-class writer. My parents understood how I felt. They told me that even though it would be a financial problem, I could go wherever I would be happiest. But as I was always careful with money, I wasn't sure what to do.

    One of the schools that offered me a full ride had an informational dinner one night in the spring. Considering my parents' financial difficulties, I decided to drive the 45 minutes and attend. At first, all I had planned to do was smile politely, eat free food, listen quietly. But I surprised myself.

    At dinner the president of the university talked about the wonderful activities on campus (校园) including guest lectures and social gatherings. He also made it perfectly clear that free food would be offered at all future events. He continued with explanations of professors, class sizes, activities, and sporting events on campus. As he spoke, I began to realize that this school, though not as good as my first choice, might be the best one for me. It seemed small yet with many great programs. It seemed challenging yet caring.

    As the president ended his speech, we clapped politely and pushed back our chairs. As I walked out of that door, a feeling of comfort washed over me. Looking at the campus that night, I realized that I would be spending the next four years right there.

    In all honesty, my university is not as well-known as my “dream” university. However, it turned out to be the right choice of schools for me.

    Many people all over the world enjoy an alcoholic drink, such as wine or beer, during dinner. Many people raise a glass of alcohol to celebrate a wedding or a birthday. And having drinks after work with friends and co-workers is called "happy hour".

    All these situations are considered "social drinking" because they happen at social events. But when does "social drinking" become problem drinking?

    According to the World Health Organization alcohol abuse kills 3.3 million people each year. That is six percent of all deaths around the world. And in a new report on alcohol use around the world, the WHO says alcohol can create dependency, or addiction, in some people. The report also warns that alcohol use can increase the risk of developing more than 200 diseases, including some kinds of cancers. And, the WHO says alcohol abuse can put people at greater risk of infectious diseases, such as tuberculosis(肺结核), pneumonia (肺炎)and HIV.

    WHO Mental Health and Substance Abuse Director Shekhar Saxena says the organization is concerned about drinking among young people between the ages 15 and 19. And it is most concerned about "binge-drinking", or an extended period of heavy drinking.

    The report concludes that worldwide 16 percent of drinkers over the age of 15 engage in binge-drinking, which is much more harmful than other kind of drinking and causes the most harm in terms of accidents, self-harm and harm to others. High income countries have the highest alcohol consumption and also the highest prevalence(盛行) of binge-drinking.

    The report also found that the highest rates of alcohol-linked deaths are in Europe, followed by the West Pacific and then the Americans. The report also finds Europe is the area with the highest alcohol use. Central and Eastern Europe are especially high.

    The World Health Organization suggests ways countries can protect people from alcohol abuse. These include increasing taxes on alcohol sales, raising the drinking age limit, and controlling the marketing of alcoholic beverages.

    Fish have different personalities which change as they experience life's highs and lows, according to British biologists.

    Researchers identified different "personalities" in their fish by observing the boldness(大胆) or shyness of individuals, according to The Nature. Like people, some fish are very confident in the face of novelty or conflict, while others are silent and fearful.

    The scientists selected particularly bold and shy rainbow trout(虹鳟鱼), and tested whether they changed their outlook depending on what life threw at them. They arranged some fish to fight and others to watch to see how both the participants and observers responded to victories and defeats. Winning or losing a fight, or even watching fellow fish overcome the difficulties influenced the future behavior of the creatures studied in the lab.

    The researchers made fish compete with much larger or smaller opponents(对手), to ensure that they would win or lose their fights. These bold fish that won their fights tended to be even bolder when later presented with a novel food item; losing their fight caused them to be much more cautious.

    Fish also learn by watching others. Bold fish watching a shy fish exploring a mystery object were much more nervous when later given a novel item for themselves.

    Predictably, shy fish that won a fight also gained more confidence, but surprisingly, shy fish that lost their fights also grew bolder when exploring strange new food, Sneddon said, adding that this could be due to what she calls a "desperado effect"(亡命徒效应).

    The new research suggests that animals can gradually adapt(使适应) their personalities. The results agree with the effects that life experience can have on humans.
