【答案解析】[听力原文]
Sugata Mitra has a theory about education. He believes that if children have questions and a desire to know more, then they will learn, even if they do not have teachers. Mitra began to develop his theory when he was working in New Dehli. His office was near slum called Kalkaii, which is an area of great poverty. Like other slums, it is dirty and the houses are in poor condition. Often, the children do not get a good education. And if the school is too far away, they do not get an education at all. Mitra"s theory about education led him to think about the curious nature of children. This led him to his work with computers. He believes computers can help improve education in the developing world. Mitra decided to test his education theory. One day, he cut a hole in a wall of his office. This wall was in the direction of the slum. Then he put a computer in the hole and connected it to power. This computer was for the children of the community. He wanted to know if they would learn just by using a computer and the Internet. This was the first time any of the children saw a computer. They did not know how to use it. No one showed the children how to use the computer. But the children became interested in the computer very quickly and explored it. And without any help, they discovered how to use it. The Hole in the Wall experiment proved something important. If you encourage individual learning and give children interesting questions to explore, then curiosity quickly starts the learning process.
