环球慢速英语 脸盲症(3)（在线收听）

Voice 2: The brain is a complex and amazing organ. Scientists do not understand exactly how the brain sees, processes, and recognizes faces. But they do know one thing. When a baby is born, he already has the ability to recognize faces. They say that babies know the difference between a male and a female face. Babies can usually recognize their mothers. And a baby likes to look at his mother's face more than any other face.

Voice 1: But this part of the brain does not work for a person who is face blind. Face blindness is a condition that prevents a person from recognizing faces. However, a person's ability to see is not affected.

声音1：但对于脸盲的人来说，大脑的这一部分并不起作用。脸盲症是一种阻止人们识别面部的疾病。然而，人们的视觉却不受影响。
