A 33-year-old financial analyst in California recently quit his job to devote himself to an unpaid job teaching math on the Internet, and his lessons are reaching almost 100,000 people a month. Salman Khan’s voice is heard every day on the net --- by tens of thousands of students around the world who are hungry for help learning math. He has posted 1,200 lessons on YouTube ... lessons that appear on an electronic blackboard, which range from basic addition to advanced mathematics for science and finance. And they are free.
Khan lives in Silicon Valley, with his wife, a doctor, and their new baby. He got the idea for his “Khan Academy” four years ago, when he taught a young cousin how to convert kilograms to grams. With Khan’s help, the cousin got good at math, and Khan began a new career.
Now, Khan records his lessons himself, but he never goes on camera. “It feels like my voice in their head. You’re looking at it and it feels like someone’s over your shoulder talking in your ear, as opposed to someone at the blackboard, which is distant from you,” he said.
When Springfield High School in Palo Alto, California invited Khan to speak in person --- he immediately connected to the students there.
The idea of short lessons that can be played over and over again attracted high school senior Bridget Meaney. She says she had trouble with math in the seventh grade. “I think the teachers are good, but they can’t teach at a speed that’s perfect for everyone,” she said. “I like the idea of learning something in class but then going back and pressing pause or rewind and actually getting a deeper understanding of it.”
Originally, Khan kept his lessons short because of YouTube restrictions. Now, he thinks short is better. “Education researchers now tell me that 10 minutes is how long someone can have a high level of concentration. And anything beyond that and your brain switches off,” he said.
For Khan, teaching math, science, and finance is just the beginning. He says he’s ready to expand his YouTube site to include other subjects as well.

A. His success in helping his cousin learn math.

A. He’s too shy to show his face on camera.
B. It’s restricted by YouTube for education videos.
C. He wants to keep distance from the viewers.
D. He wants to create a more relaxed learning atmosphere.
3. From the passage, we know that ________.
A. Khan travels to many schools to promote his lessons
B. Khan plans to include more subjects in the future
C. Khan gives live math lessons every day for free
D. Khan set up the Khan Academy with his wife
4.Why does Bridget Meaney like Khan’s lessons?
A. Khan teaches seventh grade math better than her teacher.
B. The lessons can be watched repeatedly until fully understood.
C. She can perfectly follow the pace of Khan’s teaching.
D. She cannot concentrate when learning in class.
5.What does Khan mean by “short is better” in the 6th paragraph?
A. Keeping the lessons short can ensure better concentration.
B. YouTube recommends short lessons for its site.
C. Short lessons encourage students to return to the website.
D. Students enjoy short mathematics lessons more.

Wednesday, October 29,2008.
The United States federal government had two young men in the state of Tennessee arrested on October 22 on unknown charges.
In court documents published on Monday, it came to light that the men had discussed attacking an African – American school and killing 14 of them.
Another crime was about planning to murder Presidential candidate Barack Obama. According to their affidavits (口供), the suspects’ “final act of violence” would be like this: when they attacked Obama they would wear white suits and top hats and drive “their vehicle as fast as they could toward Obama shooting at him from the windows.”
The two suspects are Paul Schlesselman, 18, of West Helena, Arkansas and Daniel Cowart, 20, of Bells, Tennessee. According to the court papers, they met last month over the Internet through a friend. Schlesselman and Cowart are believed to share “very strong views” about White Power.
Schlesselman listed “being racist” as his occupation on his MySpace page. He further wrote: “I'm white. I'm proud. I get angry. I like guns.”
Cowart also had a MySpace page on which photos of guns were presented under a heading of “My Guns”. On his page he wrote, “Better to die quick fighting on your feet than to live forever begging on your knees.”
Some have questioned the pair's ability to carry out the charged plan, but authorities have been very concerned about Obama as the first black presidential candidate from a major party.
“We honestly don't know if they had the ability or the skill to carry out the kind of plan that they talked about.” said Malcolm Wiley, of the United Satates Secret Service in an interview with The New York Times. “But we take any threat seriously no matter how big or how small it is.”
Cowart and Schlesselman are scheduled to appear before a judge on Thursady.
