This is the text (if you need help).
A British newspaper has said that a third of the world's top athletes at the 2011 World Athletics Championships in South Korea cheated by using drugs. A study showed that 29-34 per cent of the athletes used performance-enhancing drugs in the year before the games. Reporters say that the International Association of Athletics Federations (IAAF) knew about the report but blocked it. The IAAF said there were many things wrong with it.
The report is a big shock to the athletics world. The newspaper said that a third of the medal winners in endurance races had unusual blood readings. The World Anti-Doping Agency (WADA) said it would investigate the report. The lead author of the report said that he and his co-workers were told not to discuss their research or the report. He said he thought that the IAAF and WADA "just blocked the whole thing".
