Problem: 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.

The Education of Henry Adams by Henry Adams Published in 1918, the book was an autobiography. Born in one of America's most famous political families, Adams provides insight into his family, including his experience as private secretary to his father, minister to England during the American Civil war. Leaves of Grass by Walt Whitman When Whitman published Leaves of Grass in 1855, he wanted to accurately describe the American experience and reflect the great changes in the American literary world that had taken place during his lifetime. Poems by Emily Dickinson An enthusiastic poet whose works have had considerable influence on modern poetry, Dickson's frequent use of dashes, occasional capitalization of nouns, and unconventional metaphors have contributed to her reputation as one of the most inventive poets of the 19thcentury American literature. However, most of her poems were not published during her lifetime. The Song of Hiawatha by Henry Wadsworth Longfellow First published in 1855, this is Longfellow's most popular and most recognized poem, the heroic life and death of a magic American Indian, sent by the Great Spirit to guide the nations in the ways of peace.
