听力原文： There are so many things going on in our modern lives, and change happens so quickly. It is hard to imagine a time when things were slower and you could really see a new thing come into your life and to remember the day or the year when those things happened. I know that today, for example, there, are many instances of second and third generations of things, such as televisions or radios, when some of us were not even aware that there was a first generation. A friend of mine was born at the end of the last century, and talking to her, I really got a sense of her being a living history book, of being able to talk about the changes in her own life and to know that these changes were really the changes that society was going through. She gets really excited, for example, when she talks about the first time she ever saw a camera, and even more excited when she saw herself in the picture that the photographer took. She lived in a small town, and at the time that she was very young, there were no cars or trains in her town at all. As she grew up, cars and trains came in, and she remembers her first ride with a real sense of amazement that any one count move so fast. (30)
