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: After my husband died suddenly from a heart attack on the tennis court, my world crashed around me. I was overwhelmed with the responsibilities of earning a living, caring for the children and just _ . I was fortunate to find a wonderful housekeeper to care for the children during the week, but from Friday nights to Monday mornings, the children and I were alone, and frankly I was uneasy. One Friday evening I came home from work to find a big beautiful German shepherd on our doorstep. He gave every indication that he intended to enter the house and make it his home. I agreed to let him sleep in the basement until the next day. The following morning we made phone calls and checked lost-and-found ads for German's owner, but with no results. German, meanwhile, actually made himself part of the family. Saturday night he was still with us, sleeping in the basement. On Sunday I had planned to take the children on a picnic. When we stopped to get gas at a local station, we were amazed to see German racing to the gas station after us. He settled down in the back for the ride to the picnic. Monday morning I let him out for a run while the children got ready for school. He didn't come back. As evening came and German didn't appear, we were all disappointed. We were convinced that he had gone home or been found by his owner, and that we would never see him again. We were wrong. The next Friday evening, German was back on our doorstep. Again we took him in, and again he stayed until Monday morning, when our housekeeper arrived. This pattern repeated itself every weekend for almost 10 months. We grew more and more fond of German and we took comfort in his strong, warm presence, and we felt safe with him near us. Each week, between German's visits, I grew a little stronger, a little braver and more able to cope; every weekend I enjoyed his company. Then one Monday morning we patted his head and let him out for what turned out to be the last time. He never came back. We never saw or heard of German again. I think of him often. I believe German was sent because he was needed, and because no matter how abandoned and alone we feel, somehow, somewhere, someone knows and cares. We are never really alone.
