2001年考研英语Text 5翻译如下：
The human brain has no fewer than 100 billion nerve cells, each connected to several thousand others. All these connections are constantly changing, and the brain is constantly learning. This is why we can learn so much from experience. It is also why we can forget things that are no longer important to us. The brain is a very complex organ, and its complexity makes it possible for us to have such a wide range of emotions and behaviors.
人类的脑部拥有多达一千亿个神经元，每个神经元都与数千个其他神经元相连。所有这些连接都在不断变化，大脑也在不断学习。这就是为什么我们可以从经验中学到这么多。这也是为什么我们可以忘记对我们不再重要的事情。大脑是一个非常复杂的器官，其复杂性使得我们能够拥有如此广泛的情感和行为。
