人体的疼痛机制是什么样的，为什么会感觉到痛呢？

Callum: Hello and welcome to 6 Minute English, I’m Callum and with me today is

Jennifer. Hello Jennifer.

Jennifer: Hello Callum

Callum: Now Jennifer, would you like to help me with a little experiment?

Jennifer: Sure, what do you need me to do?

Callum: Just stay there, don’t move.

(Sound of slap)

Jennifer: OW! Why did you do that?

Callum: Did it hurt?

Jennifer: Of course it did!

Callum: All in the name of science and learning English Jennifer because today we’re

talking about pain! And I wanted to find out if you have a high pain threshold.

Jennifer: Well you could have just asked – you didn’t have to hit me!

Callum: Ah, yes, I suppose I could have. Sorry about that. Anyhow, moving on, here’s

today’s question.

An anaesthetic is a drug or gas used to stop pain, particularly during medical

procedures, but which language does the word come from?

Greek, Latin or Old Norse? What do you think Jennifer?

Jennifer: Well I think there are a lot of words from the Greek language when it comes to

medicine and things like that so I’ll say Greek.

Callum: OK, we’ll find out if you’re right at the end of the programme. Now Jennifer, do

you think pain is a good thing.

Jennifer: Well, I’d rather not have it, but I suppose it does tell us that something is wrong.

Callum: Do you think it would be better not to be able to feel pain.

Jennifer: Well I think that would be great, particularly after the introduction to this

programme!

Callum: Steve Pete from Washington State in the United States was born with a rare

condition which means he has never been able to feel physical pain. He was

interviewed on BBC radio about his condition. When was it first diagnosed?

Steve Pete

Well I was diagnosed with it at a young age. I was a toddler when I began chewing pretty

much the whole front portion of my tongue off.

Callum: So Jennifer, when was it diagnosed?

Jennifer: Steve says that it was diagnosed when he was a toddler – which means when he

was very young and just starting to walk, so he’s maybe 12 months, 18 months

old, something like that.

Callum: Children that age love to chew on things, don’t they?

Jennifer: Yes, they do, and in Steve’s case it was his own tongue that he chewed on!

Callum: Ouch! His parents then took him to a paediatrician, which is a children’s doctor.

Listen now to what this doctor did to test Steve.

Steve Pete

My parents took me to my paediatrician where he took a lighter, placed it underneath my foot,

held it there for a moment until my skin began to blister and then he had a pretty good idea of

what it was that my condition was.

Callum: So what did the doctor do?

Jennifer: He used a lighter to put fire under the toddler’s foot until it started to burn.

Callum: And because the child didn’t react in any way he was able to figure out that he

had this rare medical condition which is called Congenital Analgesia.

Steve’s brother shares this condition, so what kinds of problems did it cause

them when they were growing up?

Steve Pete

We were always getting into trouble, we kind of pushed things to the extreme. We’d always

end up with broken bones, we’d be visiting the hospitals frequently, wearing casts throughout

most of our childhood. So it was quite difficult.

Callum: Jennifer, what was his childhood like?

Jennifer: He says it was difficult. They made regular visits to hospitals and spent a lot of

time wearing casts – a cast is the thick plaster protection that is put on to

broken arms and legs. They got lots of broken bones because they didn’t feel

pain.

Callum: So they didn’t know when to stop doing something which could be damaging

their body. Have you ever had to wear a cast?

Jennifer: Luckily I’ve had no broken bones so no, I’ve never worn a cast.

Callum: I’ve never had a cast either, but I did have a major operation this summer and

there was a lot of pain after it. But because of the pain I wasn’t able to move

around very much, but that was good, because it meant it gave my body time to

heal. If I hadn’t had that pain, I would probably have caused even more

damage.

Jennifer: I find it hard to imagine what it must be like to never feel physical pain.

Callum: I know, and in the same way Steve Pete finds it hard to imagine what it must be

like to feel pain.

Steve Pete

I’ve never really tried to imagine what it would be like to feel physical pain. I do understand

the emotional pain part though. But when it comes to empathy which is kind of interesting it is

hard for me to feel sorry for an individual who’s going through a painful situation when it’s

regarding physical pain. I do have difficulty with that.

Callum: He talks about the difficulty he has with empathy. What’s empathy Jennifer?

Jennifer: Empathy is the ability to understand someone else’s feelings and appreciate

what that they are experiencing. Because he can’t feel physical pain, he doesn’t

really feel sorry for people in painful situations.

Callum: After hearing about the problems of this condition, do you think you’d still like

not to feel pain?

Jennifer: Well I still don’t like feeling pain but I think after hearing this I realise that it’s

very useful. What about you?

Callum: I agree with that. Sometimes I would like the pain to be less but I think on

balance it’s good to have it.

Well just about time to go but before we do the answer to today’s question,

which was about the language origin of the word anaesthetic.

Which language does the word come from? Greek, Latin or Old Norse? Jennifer,

you said?

Jennifer: I thought it was Greek.

Callum: And you were absolutely right, well done, congratulations with that.

That’s all from us today. Thanks very much Jennifer.

Jennifer: Thanks.

Callum: And I should say in case anyone was worried, no presenters were harmed during

the making of this programme. Goodbye.

Jennifer: Goodbye.
