A famous teacher was speaking to the students at our school. He began his lesson by holding up a PS100 bill. Then he said to the three hundred students, "Who would like to have this PS100 bill?" The students began to put up their hands at once. Then he said, "I am going to give this bill to one of you, but first, let me do this." He then made this bill into a ball. Then he said, "Who wants it?" Hands went into the air. "Well," he said, "What if I do this?" and he dropped it on the floor and stepped on it. He picked up the dirty, crumpled bill and said, "Who still wants it?" _ "My friends," he said, "You've learned a valued lesson today. No matter what I did to the money, you still wanted it because it didn't go down in value. It was still worth PS100. Many times in our lives, we're dropped, crumpled, and stepped on by the chances we take and the things that happen to us. We feel as if we are worth nothing. But remember, no matter what has happened to you, you will never lose your value. You are always valuable to those who love you. Your value doesn't come from what you drop or whom you know,but WHO YOU ARE . You are special and valuable. Don't ever forget it! Even though the money was dirty, it _ . A) went up in value B) was worth much C) didn't reduce in value D) was still ours

A class with tens or even hundreds of thousands of students might sound like a teacher's bad dream. But a big idea in higher education these days is the massive open online course, or MOOC. Some universities offer free, non-credit MOOCs available to anyone in the world. Others charge for courses and provide credits. The idea is still developing. So far, most massive open online courses are in computer science, technology, mechanics and engineering. For example, students around the world are taking a free course called "Building a Computer Search Engine." Two computer scientists, Sebastian Thrun and David Evans, are offering this course throughudacity.com. There are no education requirements for the course. The students watch short videos. Then, says Mr. Evans, they take informal quizzes after the videos each week for six weeks. DAVID EVANS: "Quizzes are part of the lecture to keep students engaged and keep them thinking, for students to be able to check that they understood what we covered. Those are not graded and students try those as often as they wish. They can repeatedly watch the videos and take the quizzes whenever they want." Students receive homework. They join online groups to exchange questions and answers about the course. The teachers hold office hours to answer questions that the students have voted to send them. They also present their own questions and observations to the students in order to help them make a deeper impression of the course. The students take a final examination to show where they rate in the class Everyone who finishes the course receives a grade and proof of completion. Top students get letters documenting their work. Mr. Thrun started Udacity, which supports free MOOCs.Udacityhopes to make a profit in the future by connecting possible employers with interested students. On his Stanford homepage he says he wants to " _ " education. "Education", he says, should be free, accessible for all, anywhere and any time According to the passage, the students who take the course Building a Computer Engine _ . A) will take an informal quiz every day B) learn mainly by watching short videos on the Internet C) can ask the teachers any question about the course anytime on the Internet D) will get a grade and a proof of completion if they do well in the final examination

Ques: 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 You Tube --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... 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.
