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: When I was almost six and Jem nearly ten,our summertime boundaries were Mrs. Henry Lafayette Dubose's house two doors to the north of us,and the Radley Place three doors to the south.The Radley Place was said to be a ghostly house That was the summer Dill came to us. Early one morning Jem and I heard something next door in Miss Rachel Haverford's baekyard.We looked to the right and found someone looking at us. "Hey." "Hey yourself.How old are you?"asked Jem. "Goin' on seven.'' "You look right puny for goin' on seven."said Jem. "I'm little but I'm old."he said. Jem looked at him,"Charles Baker Harris? Lord, what a name!" "Folks call me Dill,"said Dill,struggling under the fence "Do better if you go over it instead of under it,"I said"Where'd you come from? " Dill,from Meridian,Mississippi,was spending the summer with his aunt,Miss Rachel.His family was from Maycomb County originally;his mother worked for a photographer in Meridian,had entered his picture in a Beautiful Child contest and won five dollars.She gave the money to Dill,who went to the picture show twenty times on it. "Don't have any picture shows here."said Jem."Ever see anything good?" Dill had seen Dracula,a revelation that moved Jem to envy him."Tell it to us." Dill was a curiosity He was a year my senior but I towered over him. When Dill reduced Dracula to dust,and Jem said the show sounded better than the book ,I asked Dill where his father was,"You ain't said anything about him." "I haven't got one." "Is he dead?" "No'' "Then if he's not dead you've got one,haven't you? " Seeing Dill uneasy, Jem told me to hush,a sure sign that Dill had been studied and found acceptable.Thereafter the summer passed in drama sharing.Dill played the character parts before us-the ape in Tarzan, Mr. Crabtree in The Rover Boys.Thus we came to know Dill as a pocket Merlin,whose head was full of strange plans and fancies But by the end of August Dill gave us the idea of making Boo Radley come out.
