听力原文：M: Ow！That hurts! W: What happened? Did you cut yourself?. M: Yes—on the edge of this paper. How can such a little cut hurt so much? I' m not even bleeding, but my finger really hurts. W: You know, I read something about that. It turns out that a little cut on a finger can hurt a lot more than a big cut somewhere else. M: Why? That doesn't make any sense. W: Actually, it does. There are more nerve endings in your hands than almost anywhere else in the body, and it' s the nerve endings that allow you to feel pain. M: I guess that' s true. W: Also, a little cut like yours won' t damage the nerve endings, just irritate them. If they were damaged, you' d feel less pain, but the wound could be more serious. M: So I suppose I should be happy my finger hurts so much? W: Right. Now go get yourself bandage. M: Why? You just told me it' s not serious. W: It' s not, but it does seem to be bothering you. Putting a bandage over the cut will keep the skin from drying and will help keep the skin together. If the skin stays together, the nerve endings won' t be exposed, and the cut will hurt less. (24)
