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 15minutes．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．"

    Early birds-people who feel most energetic in the morning-tend to make healthier food choices throughout the day than night owls(夜猫子) , according to a new study.

    "Evening types had more irregular meal times," notes study author Mirkka Maukonen, studying human nutrition and obesity(肥胖) in Finland.

    Her study focused on people's risk of heart disease and their eating habits. Participants described when and what they had eaten during the past two days.

Maukonen's team then looked at l,854 people's lifestyle. After analyzing the data, the researchers found that both morning and evening people consumed approximately the same number of calories over a whole day.  However, night owls tended to eat their meals later than early birds. Before 10:00 am, night owls consumed less food than early birds. More of their calories came from sugar. After 8:00 pm, the night owls ate more sugar and fat. Meanwhile ,early birds ate more protein during both the morning and the evening hours.

    "Night owls tend to be less healthy than early risers," notes Courtney Peterson who studies diet and meal timing. "They are more likely to get heart disease or cancer. The fact that night owls tend to eat more junk food probably plays a role," Peterson says. "Other factors(因素) also can ruin a night owl's health. Night owls generally sleep worse," says Peterson. "Poor sleep has been linked to unhealthy food choices. "

    Peterson and Maukonen say night owls tend to have poor eating habits. But that doesn't necessarily mean that being a night owl makes a person a poor eater. It could be the reverse- eating poorly could affect people's sleep habits.

"The new findings should serve as a wake-up call to night owls. For them, the new results should encourage paying attention to healthier lifestyle choices," says Maukonen. 28. How did Maukonen do research about people's risk of heart disease?

    This activity will melt away the pounds, build your body and leave you on an emotional high. Yet the form of exercise, the fitness trend of the year, does not require gym membership or a personal trainer. All you need to do is walk.

    “Walking is a refreshing alternative to complicated aerobic ( 氧) routines and overpriced gym membership,” says personal trainer Lucy Knight, author of a new book on the exercise. “It is free, enjoyable and already a part of everyday life. All you need to do is correct your technique, walk faster and for longer and you will lose weight.”

    There is much evidence of the benefits of walking. Scientists at the University of Pittsburgh recently discovered that overweight people who walked briskly ( 快) for 30 to 60 minutes a day lost weight even if they didn't change any other lifestyle habits. Another American study found that people who walked for at least four hours a week gained less weight than couch potatoes as they got older. Researchers at the University of Massachusetts medical school found that people who walked every day had 25 percent fewer colds than those who sat a lot. Best of all, walking makes you feel good about yourself. “For people suffering from depression, walking three to four times a week for 30 minutes has been shown to lift their mood,” says Knight.

    But how to walk your way to weight loss and wellness? Health experts recommend that we should walk 10,000 steps a day to stay healthy. Actually you would probably need to walk at least 16,000 steps a day to lose weight. “Your workout plans depend on your level of fitness. You should aim to progress by increasing your walking time by five minutes every two weeks, and walk a bit faster. In just three months, the results should speak for themselves,” says Knight.

    Italian Joseph Caspar Mezzofanti was said to have spoken more than 38 languages fluently at the time of his death in 1849, a skill that would have been useful in today's globalized economy. Unfortunately, when it comes to the high school Spanish lesson in the decades, most people nowadays have remembered that there is nothing more complex than "Donde esta la biblioteca". So we set out to uncover what's involved in learning a foreign language and which methods work best.

    Some advertisements say that some language learners believe they're just a 15-minute audio tape away from becoming UN interpreters. But experts say these get-fluent-fast programs are a complete sham." Actually, there is hardly a shortcut that can do that," says Dekeyser, a professor of second language acquisition at the University of Maryland." The only way to learn a language is to make quite a bit of effort on a daily basis."

    Many experts agree that the ideal learning method for language learners really depends on the individual." Find the method that works for you and stick with it," says Simcott, a polyglot who has professionally worked in over 14 languages at once for the British Foreign Service." If audio works for you, do audio. If you like taking classes, do classes. But remember to keep practicing every day."

    However, not all people are created equal. Some may have talent for language learning, but it doesn't mean they can passively await fluency. "Practice is an effective learning method," says Davidson." The more time that you spend during the day speaking your second language, the better at it you're going to be."

    Learning from multiple people is also a good way, especially when you are attempting to cultivate a native accent. "When you are exposed to a lot of people, you get a much better sense of what the sound of a word is supposed to be," says Davidson. "You avoid exposing yourself to what could be features in one individual's speech patterns."

    In earliest times, men considered lightning to be one of the great mysteries (神秘的事物)of nature. Some ancient peoples believed that lightning and thunder were the weapons (武器) of the gods.

    In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs (灯泡).

    The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod (避雷针). This device (装置物) protects buildings from being damaged by lightning.

    Modern science has discovered that one stroke (闪击) of lightning has a voltage (电压) of more than 15 million volts (伏特). A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second.

    Scientists judge that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average (平均数) of one person every day.

    The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under tress. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things.

    With lightning, it is better to be safe than sorry?
