    Have you ever found yourself in this situation: You hear a song you used to sing when you were a child – a bit of nostalgia(怀旧) or "blast from the past," as we say. But it is not a distant childhood memory. The words come back to you as clearly as when you sang them all those years ago.

    Researchers at the University of Edinburgh studied the relationship between music and remembering a foreign language. They found that remembering words in a song was the best way to remember even one of the most difficult languages.

    Here is what they did. Researchers took 60 adults and randomly divided them into three groups of 20. Then they gave the groups three different types of "listen-and-repeat" learning conditions. Researchers had one group simply speak the words. They had the second group speak the words to a rhythm, or beat. And they asked the third group to sing the words.

    All three groups studied words from the Hungarian language for 15 minutes. Then they took part in a series of language tests to see what they remembered.

    Why Hungarian, you ask? Researchers said they chose Hungarian because not many people know the language. It does not share any roots with Germanic or Romance languages, such as Italian or Spanish. After the tests were over, the singers came out on top. The people who learned these new Hungarian words by singing them showed a higher overall performance. They did the best in four out of five of the tests. They also performed two times better than those who simply learned the words by speaking them.

    Dr. Katie Overy says singing could lead to new ways to learn a foreign language. The brain likes to remember things when they are contained in a catchy 3, or memorable 4, tune 5.

    Dr. Ludke said the findings could help those who struggle to learn foreign languages. On the University of Edinburgh's website Dr. Ludke writes, "This study provides the first experimental evidence that a listen-and-repeat singing method can support foreign language learning, and opens the door for future research in this area."

    A recent study surveyed 5,000 British families about their experiences with volunteering and their mental health. Participants completed the same survey every two years from 1996 to 2008.

    About 20 percent of the survey participants reported doing regular unpaid work Researchers found that these volunteers also scored highest on their mental health scores. The two were linked so directly that the more a person volunteered, the happier they were.

    One could argue a chicken-and-egg theory: happier people are more likely to have the time, money, energy and resources to give back to others. But even when researchers adjusted for education, social class and total health, the link was there, suggesting that the mental increase came from volunteering and not the other way around.

    According to Dr. Stephen G. Post, author of The Hidden Gifts of Helping, when you help others, your brain releases feel-good chemicals, which can help cells repair themselves and grow. And this translates to better health.

    So volunteering can help improve both your physical and mental health—on one condition. You have to mean it. People who volunteered for "self-oriental" reasons, either because they were forced to do so for work or school or because they were trying to get away from problems in their lives, had a mortality（死亡率）risk that was similar to those who didn't volunteer at all. It was only when people were volunteering out of a true sense of sympathy that they saw any health benefits.

    So whether it's arranging books at the library or walking dogs at the animal shelter, find a cause that's important to you and give it a try. Volunteering is a good way to develop a sense of connection that not only helps your community, but may also be good for you.

    With more and more people swimming at beaches every year, the problem of sharks (鲨鱼) takes on new importance. There are people who still insist that sharks never attack human beings unless they are bleeding or wounded, but this belief has not been clearly proved. In the past few years, on both the Atlantic and Pacific coasts, there have been cases of shark attacks which resulted in death. And just how many of the swimmers who have disappeared were victims of shark attacks will never be known. Clearly, these violent fish can be dangerous. Several species are known to attack human beings, and it is believed by some experts that certain sharks, once having tasted human blood, develop a taste for it.

    The chances that one will come across a shark are small, but certain precautions should be taken by everyone. (A precaution is something you do in order to prevent something dangerous or unpleasant from happening.) Putting hands or legs over the side of a boat in warm waters is to be avoided. Swimming far out from beaches is inviting trouble. No swimmer should go great distances from shore alone, or go into the water when nobody else is about. Skin divers, particularly those who go deep down in the water or among rocks and ledges (暗礁) that serve as hiding places for sharks, are taking unnecessary risks.

    If one is in a boat that is rubbed against by a shark, he should remember the creature is not trying to upset his boat; it is probably trying to rub off sea lice (海虱). A blow, especially on the nose, will drive it off. If a swimmer comes across a shark, he should swim away as quietly as possible, trying to avoid making it angry. He should also head for shore (岸) as quickly as possible.

    One of the most outspoken supporters that I know of women and girls is actually a man. As co­founder of the ONE Campaign, my friend Bono spends a lot of time speaking out against global poverty (贫困). Together, we're working to get out a simple, powerful message: poverty is sexist.

    Women and girls are more likely to be in poverty, less likely to get an education and more likely to suffer bad health. And when they are born into poverty, it is much more difficult for them to lift themselves and their families out of it.

    Why? One reason is that breaking out of poverty takes time­and that is a resource women around the world are short on. On average, women spend about twice as much time as men in doing the unpaid work that makes life possible for everyone, like cooking, washing, cleaning, shopping and caring. In developing countries, the gap is even much bigger. As a result, women have no time to finish their education, learn new skills, open a business, develop personal relationships or even go to the doctor. They dream of creating a better future for their children, but they can not spare the hours to put those dreams that they have into action.

    The fact that the potential of so many women and girls is going unrealized is a sad thing­but it is also an opportunity for us. We need to recognize, reduce and redistribute the burden of work that is holding them back. Because if women have time to invest (投资) in themselves and their ideas, they could transform the world.
