听力原文: Each night we alternate between two kinds of sleep: active sleep and passive sleep. The passive sleep gives our body the rest that is needed, and prepares us for active sleep, in which dreaming takes place. And we arc beginning to understand the importance of the dream period in our sleep cycles.
In passive sleep the body is at rest. We move very little. And the brain becomes very inactive, ff a person continues to sleep, she or he enters anew period, a more active period. The body goes through several changes: the brain temperature rises, blood in the brain increases, the body becomes very still and the brain goes into active state. And as the brain goes active, the eyes begin to move rapidly. And that is the sign of another change---the person is dreaming. Throughout the night, people alternate between passive and active sleep. Doctors have studied the sleep cycle and have found that everyone dreams---in fact, that everyone needs to dream in order to stay healthy. It appears we need both kind of sleep. We need passive sleep in order to rest our bodies. We need active sleep in order to dream. And dreaming helps us to rest our minds,

SECTION A CONVERSATIONS
Directions: In this section you will hear several conversations. Listen to the conversations carefully and then answer the questions that follow.
听力原文:Maggie: What started you in computers?
Greg: I built my first computer when I was in Junior High School. I was an enthusiastic reader, I studied everything I could get my hands on. Then I turned to building my own machine. From that point on, I was hooked.
Maggie: Where do you see computers as going in the future?
Greg: This will be the era of distributed devices, some of which will be in your walls, some of which you will wear, some of which will be in your cars and throughout your house, and maybe one of which will be on your desk. Devices with processors in them will be everywhere, they will be connected, and they will look less and less like traditional PCs.
Maggie: What kind of computer do you have now?
Greg: My primary machine is a heavily loaded PowerMac, which I use to write all my books and to do video editing. I've also got a Toshiba notebook which I use for all my work at the company and for email.
Maggie: There are critics who say that technology is dangerous and is moving too fast. What's your reaction?
Greg: There is criticism voiced in every generation. One can’t stop this kind of progress, so the critics you cite above are cursing the dark. That being said, it’s important to always consider the implications of the technology we create, for they have social impact.
