Oh dear, if something makes your flesh creep it means you feel frightened or disgusted by something. I don’t know why I do it. It just feels nice.
某件事让你毛骨悚然是指让你感到害怕或厌恶。我不知道自己为什么这么做。但是感觉很好。
But you’ll end up with arthritis when you’re older, you know.Arthritis is a disease that causes pain and swelling in joints of the body.
但是你老了会得关节炎的。关节炎会使全身关节疼痛肿胀。
That’s an old wives’ tale, Rob!And that means an old idea or belief that has no scientific support.
这是无稽之谈。也就是说没有科学依据的陈旧观点。
OK, if you say so, Professor. And since you’re in a scientific mood, how about answering today’s quiz question.Which type of joint can you crack? Is it …a) fibrous?b) cartilaginous?Or c) synovial?
如果你这么说，那么教授，你这么有科学头脑，回答今天的问题吧。哪种类型的关节可以掰得咔咔作响？a) 纤维状的?b) 软骨的?c) 分泌滑液的?
OK, this professor isn’t feeling too clever today.I’m going to have to take a guess and say, c) synovial.
今天本教授状态不好。我猜一下，选c) 分泌滑液的关节。
OK. Well, we’ll find out how smart you really are later on in the programme. Now let’s listen to Greg Kawchuk, Professor of Rehabilitation Medicine at the University of Alberta.Rehabilitation means the process of helping somebody get better from an illness or injury.
之后我们看你到底有多聪明。现在我们来听听阿尔伯塔大学康复医学教授Greg Kawchuk的看法。康复是指帮助某人从疾病或受伤中恢复的过程。
We’ve recently been able to use some new technology through MRI imagingto see for the first time what is actually happening inside the joint when someone pops or cracks their knuckles. And because of that we’re hopeful that we’ll be able to start to ask questions about why is it that some people can do this and other people can’t.
我们最近利用新技术，首次通过MRI（核磁共振成像）查看人们掰响指关节时，关节内部到底发生了什么。源于此，我们有望回答为什么有的人能够掰响指关节，而有的人却不能。
What does MRI stand for?
MRI是什么？
It means Magnetic Resonance Imaging.Hospitals use this technology to produce an image of the inside of a person’s body.
是指核磁共振成像。医院利用这项技术可以查看人体内的情况。
