剑桥少儿英语二级下册第七课 第一部分听力的原文，

It was a Friday afternoon. Bob invited his father’s best friend who is a famous clown to come to his class. Many children heard this and came to see the clown. The classroom was not big and there were not many chairs. So many children had to stand in the room and some children had to stay outside the classroom. The clown said a few words and quickly took out a few balls and began to throw the balls up. He threw out the balls one by one and caught one after another with his two hands and threw them out again. No balls dropped on the ground. Suddenly he threw the balls higher and higher and turned around and caught the balls again. It was interesting and exciting. Everybody gave him a big hand. The show went on for an hour, but nobody left the room.
