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: The First of May is a Bank Holiday--the first public holiday of the year in England. Most people consider it a special day ,the beginning of summer ,a day when the light lasts long into the evening ,and when we can look for warm weather .We don't always get it .We feel disappointed ,but not surprised if there are cold winds and frosts at night in May .Winter should be over .Most people know that in the past ,when farming occupied almost everyone ,the changing seasons were of great importance .In that older time there was every reason to celebrate May Day .Customs of those celebrations remain. Of these customs ,the best known is the choosing of a May Queen and the dancing round Maypole .Even these customs are little more than memories now--but in the last century it was quite common in villages and small towns ,and even in schools and colleges ,for a pretty and popular girl to be chosen Queen of the May .It was a great honour to be chosen .For a day she wore a light and flowery dress, carried garlands ,and was ceremonially crowned with flowers .She presided over a procession ,as a rule with a number of attendants ,and over the Maypole dancing and all kinds of entertainment .The Maypole was slender  tree trunk ,cut off its branches, with beautiful ribbons fastened to the top .The dancing was designed in such a way that the dancer's movements move the ribbons into a pattern. This, as you can imagine ,required skill from the dancer ,and was not achieved without practice . It's the Celtic people who celebrated the First of May as a spring festival .Their celebration seems to have had little to do with taking pleasure in early ,beautiful flowers and in warmer weather! They called it Beltane--the fire of the god Bel .They lit fires ,in the expectation that their blaze would help the sun in its struggle to regain its strength. They drove their cattle between banks of flame in the expectation that the terrified beasts would be purified  and protected from disease .A tree ,which must have been blackened with smoke ,stood in the middle of the fires ,and is thought to have been the origin of the Maypole .Their priests  made sacrifices to the goods in the hope of good harvests and sufficient store of food for the winter. There was dancing certainly ,but it was noisy and cheerful ,since its purpose was not to weave a pattern of colored ribbons ,but to drive out evil spirits from the earth and to arouse those kind spirits.
