Question: Article: Argentina's Lionel Messi has won the Golden Ball awarded to the European Footballer of the Year, becoming the sixth Barcelona player to take the award and the first since Brazilian Ronaldinho in 2005. Messi beat last year's winner Cristiano Ronaldo into second place while Barcelona midfielder Xavi Hernandez finished third in the poll results released by France Football magazine early Tuesday. Praised by Argentina great Diego Maradona as his successor, Messi won an unprecedented treble in Spain last season with Barcelona as the Catalan side swept the Champions League, the Spanish title and the Copa del Rey. The 22-year-old Messi, the first Argentine to win the world-famous award, was the top scorer in last year's Champions League with nine goals, including his superb header in the 2-0 victory over Manchester United in the final. Messi, who scored 473 of a possible 480 points, largely controlled the voting and won with a record-margin of 240 points. Real Madrid winger Ronaldo had 233 and Xavi had 170. "Honestly, I knew that I was among the favorites because Barcelona had a fruitful year in 2009," Messi was quoted as saying by the magazine. " _ The Golden Ball is very important to me. All the players who won it were great players, and some great players never won it." Barcelona had three players in the Top 5 with Andres Iniesta taking fourth ahead of former Barca player Samuel Eto'o. In an outstanding season, Messi netted(...) 38 goals in 51 games in all competitions, often leaving defenders in his wake(...) with a combination of speed, extraordinary abilities and his effective left-footed strike. Messi, who led Argentina to next year's World Cup in South Africa, recently signed a new contract with Barcelona through 2016. Messi had a good start to this season - already scoring nine goals - and put on a great display to help his club defeat archrival Real Madrid 1-0 last Sunday. "It won't be easy to confirm after a year like the one we just went through," Messi said. "I hope the next one will reach the same standards. But to win the Golden Ball two years in a row is not an easy thing." (Read by Guanny Liu. Guanny Liu is a multimedia journalist at the China Daily Web site.)

Question: Article: During the 1800s, African Americans worked long days in the fields of the American South.To ease their labor, they sang "field hollers" that they had brought from Africa.One person sang a line.Then a group of workers repeated it.The songs' words told of the hardships that people suffered.African Americans sang "shout spirituals", or joyous religious songs.They clapped their hands and stomped their feet to the music. After the Civil War, the music changed dramatically.African American music, from ballads to church music, took new forms.It also adapted dance music, called "jump-ups".which had great rhythm. Banjos became popular.A blues singer usually played a call and response with the banjo.By the early 1900s, the guitar had replaced the banjo as the main blues instrument. Northern Mississippi - called the Delta - was the center of the blues tradition.By the 1920s, the Delta had many clubs, so-called juke joints.African Americans listened and danced to music in these clubs.Some of the greatest blues men and women performed there. Blues have a soulful sound that is easy to recognize.The musical notes are often "bent".That is, they are changed slightly to give a song more strength.Whatever their origin, these bent notes most often define the blues. Lyrics are the words of a song.Blues lyrics describe everyday life.The lyrics, often about relationships between men and women, are often very intense and personal.They tell about sorrow and overwork.They tell about finding or losing love, having money or being broke, being happy or sad and lonely.The lyrics may use humor to describe life's trials and joys.They almost always use the rhythms of everyday speech.A typical blues stanza, or group of lyrics, has three lines.The second line repeats the first line.The third line has different words. By the 1940s, large numbers of African Americans had left the Delta and moved north to work. Many settled in Chicago.There, a new kind of "electric", or "Chicago" blues began.Many of its themes were the same, but these blues had "wailing" electric guitars and harmonicas.The music had a steady, strong drumbeat.The loud, driving Chicago blues was excellent dance music.Chicago blues led to the birth of a new music style-rock and roll.

Question: Article: Many students attend Miami University for its zoology program, hoping to become a doctor someday, but Joseph Frame has come for a different reason -- to become a vet. "Ever since I was a little boy, I've been interested in animals," Frame said, "but when I grow up, I realized that I didn't want to just take care of dogs and cats. I wanted to work with animals you wouldn't find in your house." Before coming to Miami, Frame worked with his vet Dr. Reid. He learned about the details of being a vet from him. Working with small animals, Frame observed many procedures there. Frame also worked with another vet at Oxford University during his first year at Miami, which involved a leadership position. "I'm in charge of a high school kid," Fram said, "He sometimes needs to be motivated. I like his support system." To realize his goal, Frame began working at the Wilds in Cumberland, Ohio after he met Reid. The Wilds is a non-profit conservation center and is the home for rare and endangered animals. The Wilds combines the concepts of conservation science and education programs to mainly children. After his first year at Miami, Frame began to educate children about the animals. "I think teaching children is an enjoyable experience, especially when they're really interested in animals," Frame said. Frame also explained if a vet school didn't work out, he would be interested in working in animal education. "I would at least have a Zoology degree," Frame said, "The wilds is connected to many zoos all over the country, so I'm sure I can find a job in education." For now, Frame plans to continue working at the wilds this coming summer with a new job at hand, which involves teaching the public about the endangered animals they are protecting and doing shows with owls. While Frame is still an undergraduate student at Miami, he continues his passion for animals. Becoming an exotic vet may be a few years down the road, but Frame continues to work had for this dream, hoping it will become a great reality.
