Q: Article: Homework can put you in a bad mood , 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.

Q: Article: One day in l965, when I worked at View Ridge School in Seattle, a fourth-grade teacher approached me. She had a student who finished his work before all the others and needed a challenge. "Could he help in the library?" She asked. I said, "Send him along." Soon a slight, sandy-haired boy in jeans and a T-shift appeared. "Do you have a job for me?" he asked. I told him about the Dewey Decimal System for shelving books. He picked up the idea immediately. Then I showed him a stack of cards for long-overdue books that I was beginning to think had actually been returned but were misshelved with the wrong cards in them. He said, "Is it kind of a detective job?" I answered yes, and he became working. He had found three books with wrong cards by the time his teacher opened the door and announced, "Time for break!" He argued for finishing the finding job; She made the case for fresh air. She won. The next morning, he arrived early. "I want to finish these books," he said. At the end of the day, when he asked to be a librarian on a regular basis, it was easy to say yes. He worked untiringly. After a few weeks I found a note on my desk, inviting me to dinner at the boy's home. At the end of a pleasant evening, his mother announced that the family would be moving to neighbouring school district. Her son's first concern, she said, was leaving the View Ridge library. "Who will find the lost books?" he asked. When the time came, I said a reluctant good-bye. I missed him, but not for long. A few days later he came back and joyfully announced: "The librarian over there doesn't let boys work in the library. My mother got me transferred back to View Ridge. My dad will drop me off on his way to work. And if he can't, I'll walk!" I should have had an inkling such focused determination would take that young man wherever he wanted to go. What I could not have guessed, however, was that he would become a wizard of the Information Age: Bill Gates, tycoon of Microsoft and America's richest man.
