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: My father was poor in expressing his feelings. I knew that my dad loved me, but showed me love in other ways. There was one particular time in my life when this became real to me. I always believed that my parents had a good marriage, but gradually the strain on my mom and dad's relationship was quite evident. However, I was not prepared for the day when Dad had decided to leave. All that I could think of was that I was going to become a product of a divorced family. I kept telling myself that it wasn't going to happen. The night before he left, I stayed up in my room for a long time. I prayed and I cried and I wrote a long letter to my dad. I told him how much I loved him and that I would always and forever be his Krissie. As I folded my note, I stuck in a picture of me with a saying I had always heard: _ Early the next morning, as my dad left our house, I slipped my letter into one of his bags. Two weeks later, my mother told me that they decided that there were things that the both of them could and would change and that their marriage was worth saving. "Well, Dad said that when he read your letter, it made him cry. It meant a lot to him and I have hardly ever seen your dad cry. After he read your letter, he called to ask if he could come over to talk. Whatever you said really made a difference to your dad." A few days later my dad was back. We never talked about the letter. I guessed that it became a secret between us.
