听力原文：M: Do you have any dream that seems impossible to realize？

F: Hm, ever since I was a little girl, I have wanted to fly like a bird; I'd like to go back in time and meet Marco Polo; I'd also like to win the gold medal in the marathon at the Olympic Games.

M: You've got so many of them! But soon all of these dreams will come true, thanks to the magic of Virtual Reality.

F: What is Virtual Reality？

M: Virtual Reality, or VR, is a computer system with a special head-set. When you put on the head-set ,your mind will see the image as one picture.

F: Is it like when we play a game in a video arcade today？

M: Much more fascinating. In the future, when you play a VR game, you will be right inside that world, just as in real life.

F: Sounds interesting. Have these games been introduced into video arcades nowadays？

M: Only some of them. They enable you to drive a sports car, fly a plane, or fight an enemy. They are similar to present arcade games, but much more realistic. And as the technology develops, the games will become more and more amazing.

F: So you mean we would have more fun in playing computer games？

M: Yes. However, VR is not just for entertainment. One day, children will learn geography by observing foreign countries without leaving their classroom. Cars will be designed and tested as "virtual" machines first, before they are manufactured in metal. Architects will be able to build "virtual" buildings which they can walk around and inspect, before building them. VR can help us in hundreds of ways.
