    In the village of Kila Raipur, people would like to take part in their unusual Olympics. Even though the villagers don't spend millions of dollars on the sport, these games seem to be much more fun than the real Olympics!

    Now in its 77^th year, the sport took place in the village Kila Raipur in an Indian state from January 31^st to February 3^rd. A villager by the name of Inder Singh Grewal wanted to organize an event which would allow farmers to show their skills, keep their culture and just have a good time.

    Over the years, it has become popular and now includes not just the farmers, but also some of the world's finest athletes from 7 to 70 years of age. In keeping up with times, there are different modern sports, such as hockey and race and traditional ones such as tug-of-war and even Kabaddi.

    However, the ones that interest the biggest crowds are the special sports like the bull(公牛)races. In the races, bulls run at high speed against each other, with athletes balanced on small carts(手推车). Then there is the game that challenges athletes to lift bicycles with their teeth. Another sport is using their teeth to pull a car. If that is not special enough for you to get excited about this, there is a competition that allows a tractor(拖拉机) to run over an athlete's body!

    All in all, the sport not only tests the skills and strength of its athletes, but also cheers up people. The best part is that everyone, old or young, can take part in the sport. So it's no wonder that over 4,000 athletes and over a million watchers run into the small village of Kila Raipur, each year!

    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．"
