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: Dear Alice, You really have two different questions here, so we'll discuss them one at a time. Your problems at school may be a result of a number of things . You don't say much about how these classmates get along with each other. It's possible that all the students are feeling a little cautious in the first term. It's also possible that the others are unkind. If this is so, you have to find out why you are the class "outsider". In your letter you say you often offer to help others with their work. Is it possible that your classmates don't understand your offers? Could it seem that you were trying to " buy" friends with these offers? Is it possible that you took no notice of your classmates when you had your good friends near you ? They may have felt hurt at that time. It may take a time for them to believe in you if so. Try to ask one classmate directly what the problem is. If you hear a negative answer, at least you'll know what to do. Yours truly, Shelia
