兴奋剂的使用在大型赛事里是被完全禁止的,可以为什么还是会有人铤而走险呢?


Rob: Hello, I'm Rob…


Cath: And I'm Cath.


Rob: And this is 6 Minute English from BBC Learning English. Today we're talking


about doping in sport.


Cath: And a new test that might prevent some athletes cheating at the 2012 Olympics


in London next year.


Rob: Ah yes, the Olympics. That's where the pressure is really on to do well but


some athletes use some unfair techniques to get an advantage. More on that in


a moment. But first Cath, what are you most looking forward to seeing at next


year's Olympics?


Cath: I'm really looking forward to the gymnastics. I like gymnastics a lot. And


maybe something like cycling, that's always good fun.


Rob: Well it should be a great event. But Cath, I wonder if you know when the first


modern Olympics was held? Was it in:


 a) 1886


 b) 1896


 c) 1906


Cath: I'm going to go for 1906 Rob.


Rob: Are you sure?


Cath: No but that's what I'm going to go for!

Rob: OK, well, we'll see if you're right at the end of the programme. Now let's get


back to sport and some of the cheating that goes on. Athletes have been known


to take all sorts of cocktails 1 of drugs in the hope of enhancing 2 their


performance.


Cath: Enhancing – or improving their performance. And of course doing this gives


them an unfair advantage.


Rob: It does. It means their performance cannot be just judged on their physical


endurance 3. In other words, we're not just seeing their natural fitness 4 because


other substances are helping 5 them.


Cath: So this means not everyone is competing on a level playing field.


Rob: That's a good phrase! Yes, not everyone is playing by the same rules.


Cath: Of course athletes are tested for drugs and some are caught and banned from


taking part in a race.


Rob: That's true but there's one form of cheating called 'autologous blood doping'


that has been difficult to test for. And the BBC Science reporter Matt McGrath


can tell us more about this. See if you can hear what scientists have so far


failed to do…


Matt Mc Grath, BBC Science reporter


While scientists have developed tests for almost all forms of doping in sport, the one that has


caused them most trouble has been the practice of athletes storing and transfusing 6 their own


blood. It increases the number of red blood cells and give a substantial 7 boost 8 to an athletes


endurance by allowing them to carry more oxygen. Scientists have failed to develop an


effective test.


Cath: Matt McGrath says scientists have developed tests for all sports but they have


failed to develop an effective test for autologous blood doping.

Rob: Effective means a test that actually works. It's been causing scientist much


trouble – or problems – in trying to detect blood doping in athletes.


Cath: So blood doping is when athletes store and then transfuse 9 their own blood.


Transfusing is when you move blood form one person to another but in this


case the blood is being put back in the same person. Why would someone do


that?


Rob: Well apparently 10 it increases the red blood cells and that allows more oxygen to


be carried around the body. So it gives a substantial boost to an athlete's


endurance.


Cath: Substantial here means by a great amount. But Rob you mentioned earlier


there's now a test for this?


Rob: Well one is being developed. It compares the age of blood samples by looking


at the genetic 11 component 12 of red blood cells.


Cath: The genetic component. It sounds very scientific. But will it help catch any


cheats at next year's Olympics?


Rob: Well Professor David Cowan who will be running the anti-doping laboratory at


the Olympics hopes it will, if it's ready in time. What does he say the nature


of scientific research stops him doing?


Professor David Cowan, anti-doping laboratory


As a researcher we can never guarantee what we can deliver by a particular time, that's the


nature of scientific research. The progress is very exciting and we've put it another way round,


if you're an athlete be careful we may have a test in time.


Rob: So he says the nature of scientific research means he can't guarantee this new


test will be available at a particular time. It's not possible to promise an exact


completion date.

Cath: That's because scientific research is unpredictable. It doesn't always go to plan!


But he said the progress is very exciting.


Rob: Yes, he's confident it will be ready in time for the Olympics. So he's warning


athletes to be careful! This new test might catch you out.


Cath: Well I can understand there's a huge pressure to succeed and there must be a


great temptation to give yourself an extra boost as an athlete.


Rob: Yes.


Cath: So cheating is still going to happen in some form but maybe this new test


we've been hearing about will make it a little harder.


Rob: Let's hope so. And of course we mustn't forget it's only a small number of


athletes who are trying to cheat. OK Cath, I hope you haven't been cheating in


finding the answer to our question today!


Cath: No chance!


Rob: I asked you what year was the first modern Olympics held? Was it in:


 a) 1886


 b) 1896


 c) 1906


Cath: And I said I thought it was 1906 but I'm not sure.


Rob: You're wrong. The actual answer is 1896. It took place in the original


birthplace of the Olympics, in Greece. The London Olympics in 2012 will be


the 30th summer Olympics. OK, well we're almost at the end of the


programme, so Cath could you please remind us of some of the vocabulary


we've heard in today's programme?
