You might think that “global warming” means nothing more than a rise in the world's temperature. But, rising sea levels caused by it have resulted in the first evacuation (撤离) of an island nation — the citizens of Tuvalu will have to leave their homeland.

    During the 20th century, sea level has risen 8～12 inches. As a result, Tuvalu has experienced lowland flooding of salt water which has polluted the country's drinking water.

    Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.

    Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their green house gas emissions (排放), which are a main cause of global warming.“By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years,” Laupepa told the BBC.

    Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.

    Tuvalu is not the only country that is vulnerable (易受影响的) to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311 000 an“endangered nation”.

    Teenagers who spend hours in front of the television may have a poorer diet as young adults.

    A study, which included nearly 1,400 high school students, found those who watched TV for five hours or more per day had less healthy diets than peers(同龄人) five years later. Why does this happen? Should the parents take any measures?

    On the one hand, people who spend a lot of time in front of the TV, especially teenagers, may snack more, and that may affect their long-term diet quality.

    On the other hand, TV ads for fast food, sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.

    Lead researcher Dr. Daheia J. Barr-Anderson, of the University of Minnesota in Minneapolis, told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food, those who'd watched less than two hours per day had the highest intake(吸收) of fruits, vegetables, whole grains and high-calcium food. In her opinion, parents should limit and monitor TV viewing.

    As far as I am concerned, children should watch no more than two hours of television per day. And parents should set a good example by eating right, being physically active and curbing their own TV time.

    Confident, smart and high-tech, they're followers of pop culture and know what social networking is all about. They're tweens, children between the ages of 10 and 12. These young people are no longer little kids but they are not yet teenagers, because tweens are in a state of transition (转变).

    The tween years are hard for children. From a social point of view, tweens are dealing with quite a lot. They have to face changing relationships, middle school and a whole lot of pressure (压力) to succeed and fit in. They may become angry over seemingly small things. A bad test grade, an argument with a friend, a bad day on the ball field, or a request to clean a bedroom might set them off.

    Elizabeth Hartley-Brewer, a parenting expert in London and author of Talking to Tweens, says, "The tween years are when young people begin to realize the wider world and to see themselves as separate from their families."

    Right now, tweens' friends are everything to them. It's universal for the age, but they show it in different ways. For boys, the whole friendship thing is through technology and sports. Girls like to talk.

    Tweens are also a hot market. What do tweens consider cool? Music is at the top of the cool list, followed by going to the movies. "Being smart" comes third, tied with video games, followed by electronics, sports, fashion and protecting the environment, according to a report.

    Undoubtedly, tweens have great spending power in the United States. It was the tween market that made Justin Bieber and Harry Potter household names. Retailers(零售商) know tweens are a hot market for clothes, music and entertainment. Tweens have their own sense of fashion and enjoy their own parts of popular culture.
