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.

Now, solve this instance: Article: Some young Cambodians are learning a new sport -- skateboarding. The country's first skateboard park is located on the grounds of a local charity group at the edge of Phnom Penh, the capital. Sports like Khmer boxing and soccer are wildly popular in Cambodia. But Chea, who has been skating for 6 months, says skating has already become his favorite sport. The skaters are learning tricks like launching off a jump or half-pipe and flying through the air on their narrow wooden boards. A non-governmental organization called Skateistan Cambodia organizes weekly programs at the park. Skateistan started its work in Afghanistan years ago. Rory Burke is working with the group which expanded to Cambodia last year. Rory Burke points out, "Yeah, it's definitely not a typical Cambodian pastime . And I think the idea of 'why skateboarding' is that it's not been done before here. We want to use skateboarding as something saying, 'Hey, this is new, this is something different.And that kind of itself becomes _ . People see it and they think and they say, 'Wow, what is that?' and they want to get involved. " Skateistan partners with local groups that work with young people. The park is on the grounds of the group known as PSE, where children attend school and learn a trade. There are almost one hundred twenty participants. They all come from troubled lives. Seventeen-year-old Sang Rotha is a student at PSE. "Sometimes I don't do well in subjects like math," he says, "I feel bad when I find it hard to keep up with my lessons. So that is why I skateboard ---to improve my bad feelings. ', He says he began skateboarding more than a year ago. Before he started training, it seemed very easy. But it was very difficult to learn tricks, and he got hurt a lot from falling off. Rory Burke says learning to deal with the difficulties is part of the lesson for these young skateboarders.
