Article: Are you a big fan of pirate stories? Do you know how to talk like a pirate? You can have fun on September 19th. This special holiday is called International Talk Like A Pirate Day. It was invented in 1995 by two young Americans, John Baur and Mark Summers. These two good friends came up with this idea when they were playing racquetball, and began to talk like pirates. At that moment, they thought, "Young people are interested in pirate, but there is no such a chance for people to get together to share it. Why not have a day when everybody talks like a pirate?" They decided to make September 19th the date. Since then, Baur and Summers have tried hard to promote Talk Like A Pirate Day. As Baur said, "We've talked like pirates, and encouraged several of our friends to do so every September 19th." At first, this day was only known by a few people. In 2002, Baur and Summers sent a letter about their invented holiday to Dave Barry. This columnist really liked their idea. He promoted the holiday and made it known to more and more people. Now, it has really become an international holiday. On Talk Like A Pirate Day, you need to dress like a pirate. You should wear a big hat or maybe cover one of your eyes. You can pretend to be any kind of pirate that you can find in any story or movie. Having fun and being relaxed are not the only best things about the holiday. Young people share the same interest and childhood dreams that day. That's why it is welcomed by so many people, especially young people. Unlike traditional holidays, International Talk Like A Pirate Day is a brand new holiday which is invented by the youth themselves and celebrated by themselves too. Because of Baur and Summers' imagination and creativity, thousands of young people's pirate dream come true. Next time, when you have a good idea, why not share it with your fiends and insist on your belief? Maybe you can create another wonderful holiday for the youth in the future.

Article: What shapes a man's ability and skill was always a question to psychologists until a few decades ago when findings show that they for the most part come from practice ---- repetitive and endless practice. The psychologist K. Anders Ericsson of the University of Florida and his team, based on a survey of a violin class in a college of music, have found that the students whose levels are rated as "A" have spent on average over 10,000 hours on violin-practice, those with level B a bit less than 8,000 hours, and those with average or lower levels no more than 5,000 hours. The result of the survey is widely preferred because it suggests that practice makes perfect, that is, the distinction between "excellent" and "good" lies more in hard work than in natural intelligence. Malcolm Gladwell points out in his latest book Outliers: The Story of Success: "Practice isn't the thing you do once you're good. It's the thing you do that makes you good." Besides, he thinks IQ plays little part in the formation and development of ability. "When one has an IQ of 120," writes he, "what is beyond it does not make an evidential difference in real life." However, scientists' experimental results are quite different from the psychologists'. Their findings show success in many areas depends on intelligence --- and not a little. David Lubinski and Camilla Benbow of Vanderbilt University, with their research group, carried out a milestone research. They selected from Youth Talented Search 2000 teenagers of or under 13 whose SAT results ranked top1%. After tracking the achievements the 2,000 "wonder children" made in academy and career, Lubinski and Benbow's group found that those ranking top 1% have more possibility (averagely by two to four times) to get a doctor's degree, a certificate, and publish academic theses and works than those ranking top 9%. As a conclusion, it's a great advantage in the real world to have a high IQ.

Article: Nelson Mandela was a figure of international fame, and many details of his life and career were public knowledge. But here are four things you may not have known about the late South African leader. 1. He was a boxing fan. In his youth, Nelson Mandela enjoyed boxing and long-distance running. Even during the 27 years he spent in prison, he would exercise every morning. "I did not enjoy the violence of boxing so much as the science of it. I was curious by how one moved one's body to protect oneself, how one used a strategy both to attack and retreat, how one paced oneself over a match," he wrote in his autobiography Long Walk to Freedom. 2. His original name was not Nelson. Rolihlahla Mandela was nine years old when a teacher at the primary Methodist school where he was studying in Qunu, South Africa, gave him an English name "Nelson" in accordance with the custom to give all school children Christian names. 3. He forgot his glasses when he was released from prison. Mr. Mandela's release on 11 February 1990 followed years of political pressure against apartheid . Mr. Mandela's reading glasses stayed behind in prison Mr. Mandela and his then-wife Winnie were taken to the centre of Cape Town to address a huge and exciting crowd. But when he pulled out the text of his speech, he realized he had forgotten his glasses and had to borrow Winnie's. 4. He had his own law firm, but it took him years to get a law degree. Mr. Mandela studied law on and off for 50 years from 1939, failing about half the courses he took. A two-year diploma in law on top of his university degree allowed him to practice, and in August 1952, he and Oliver Tambo set up South Africa's first black law firm, Mandela and Tambo, in Johannesburg. He kept on studying hard to finally secure a law degree while in prison in 1989.
