One example: 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: Article: Americans Spend Their Free Time In Various Ways America is a country of sports--of hunting,fishing and swimming,and of team sports like baseball and football.Millions of Americans watch their favorite sports on television.They also like to play in community orchestras ,make their own films or recordings,go camping,visit museums,attend lectures,travel,garden,read,and join in hundreds of other activities.The people also enjoy building things for their homes,sewing their own clothes,even making their own photographs.They do these things for fun as well as for economy. But as much as Americans enjoy their free time,the country is at the same time a"self-improvement" country.More than 25 million adults continue their education,chiefly by going to school in the evening, during their own free time,at their own expense.Added to the time spent on personal activities,Americans a1so devote a great amount of their time to the varied needs of their communities.Many hospitals,schools,libraries,museums,parks,community centers,and organizations that assist the poor depend on the many hours citizens devote to these activities,often without any pay. Why do they do it? There are several answers.The idea of cooperating and sharing responsibility with one another for the benefit of all is as old as the country itself. When the country was first founded in 1776,it was necessary for the settlers to work together to live.They had crossed dangerous seas and risked all they had in their struggle for political and religious freedom.There remains among many Americans a distrust of central government.People still prefer to do things themselves within their communities,rather than give the government more control. Sometimes people offer their time because they wish to accomplish something for which no money is paid,to do something that will be of benefit to the entire community.It is true that some people use their _ because they are truly interested in the work;or they are learning from the experience. No matter what the reason is,hundreds of thousands of so-called leisure hours are put into hard,unpaid work on one or another community need.
