B. Listen to a talk about sleep.

It's clear that everyone needs to sleep. Most people rarely think about how or why they sleep however. We know that if we sleep well we feel rested. If we don't sleep enough, we often feel tired and irritable. It seems that there are two purposes or physical rest and emotional or psychological rest. We need to rest our bodies and our minds. Both are important in order for us to be healthy.

Each night we alternate between two kinds of sleep: active sleep and passive sleep. passive sleep gives our body the rest that is needed and prepares us for active sleep in which dreaming occurs. And we are beginning to understand the importance of the dream stage in our sleep cycles.

Lets look at the different kinds of sleep. They are quite different. In passive sleep, the body is at rest. The heart slows down. The body processes become very slow.

We move very little. And the brain becomes very inactive. This stage of sleep is known as slow-wave sleep because the brain waves move in a very slow regular rhythm. If a person continues to sleep, she or he enters a new stage, a more active stage.

The body goes through several changes: the brain temperature rises, the amount of blood in the brain increases, the body becomes very, very still, and the brain goes from being very inactive to being active. And as the brain becomes more active, the eyes begin to move rapidly When the eyes begin to move, this is a sign of another change--the change is that the person is dreaming.

Throughout the night, people alternate between passive and active sleep. The brain rests then it becomes active, then dreaming occurs. The cycle is repeated: the brain rests, then it becomes active, then dreaming occurs. This cycle is repeated several times throughout the night. During eight hours of sleep people dream for a total of one and a half hours, on the average.

All people experience these dream cycles. Many people say they don't dream, or that they rarely dream. 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 kinds 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.

很明显，每个人都需要睡觉。然而，大多数人很少考虑如何或为什么睡觉。我们知道，如果我们睡得好，我们会感到休息。如果我们睡眠不足，我们经常感到疲倦和烦躁。似乎有两个目的或身体休息和情感或心理休息。我们需要休息我们的身体和头脑。两者都很重要，以便我们保持健康。

每天晚上，我们在两种睡眠之间交替：主动睡眠和被动睡眠。被动睡眠为我们的身体提供了所需的休息，并让我们为做梦的主动睡眠做好准备。我们开始明白梦阶段在我们的睡眠周期中的重要性。

让我们看看不同种类的睡眠。它们完全不同。在被动睡眠中，身体处于休息状态。心脏减慢了。身体过程变得非常缓慢。我们移动很少。大脑变得非常不活跃。这个睡眠阶段被称为慢波睡眠，因为脑电波以非常缓慢的规律节奏移动。如果一个人继续睡觉，她或他进入一个新的阶段，一个更活跃的阶段。

身体经历了几个变化：大脑温度升高，大脑中的血液量增加，身体变得非常非常静止，大脑从非常不活跃到活跃。当大脑变得更加活跃时，眼睛开始快速移动，当眼睛开始移动时，这是另一个变化的标志——变化是人在做梦。整晚，人们在被动睡眠和主动睡眠之间交替。大脑休息，然后它变得活跃，然后做梦发生。循环被重复：大脑休息，然后它变得活跃，然后做梦发生。这个周期在夜间重复了好几次。在八小时的睡眠中，人们平均做一个半小时的梦。

所有人都会经历这些梦想的循环。很多人说他们不做梦，或者他们很少做梦。医生们研究了睡眠周期，发现每个人实际上都梦想着，为了保持健康，每个人都需要做梦。看来我们需要两种睡眠。我们需要被动的睡眠来休息我们的身体。为了做梦，我们需要积极的睡眠。做梦有助于我们安心。
