Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

New input: Article: One kilogram----that was all it took to crown(......) the world's strongest man. German weightlifter Matthias Steiner pulled ahead of Russian rival Evgeny Chigishev to win the Olympic men's +105 kg weightlifting gold medal on Tuesday. Steiner lifted a total of 461kg, 203kg in the snatch and 258kg in the clean and jerk , to beat Chigishev by a single kilogram. The German won the battle of giants in his last lift, winning his country's first gold medal in the event at this year's Games. Steiner's winning lift was also the last effort of the sport for this Olympics at which China earned eight of the 15 golds. Steiner was born in Austria and represented his country of birth at the Athens Olympics four years ago, placing seventh in the lower 105kg category, but had a falling out with Austria's weightlifting federation afterwards. He applied for German citizenship in 2005 and got married, but his career went into deep freeze as he could not compete without a passport. He finally obtained the document last January. The German, who turns 26 on Monday, had come to these Games on a mission to win the title for his wife Susann, who died in a car accident in July last year. The German team said he used the personal tragedy to motivate himself to win the gold medal. Chigishev was the strongest in the snatch session Tuesday. He kissed his fists after a 210-kg lift that gave him a 7-kg advantage over fourth-placed Steiner going into the second event -- the clean and jerk. He let out a victorious roar after clearing 250 kg in his last lift, but the glory was short-lived as Steiner stunned everyone with his final, winning clean and jerk effort. Steiner had finished seventh in the 2004 Olympics in the 105kg weight category, and took the gold in the 2008 European Championship +105kg snatch competition, bronze in the clean and jerk and silver overall, with a total weight of 446kg. World champion Viktors Scerbatihs of Latvia settled for bronze.
