雅思时事阅读：英国《自然》杂志向叶诗文和读者道歉

　　下面雅思为大家整理了英国《自然》杂志向叶诗文道歉的文章，称其日前刊登的一篇质疑叶诗文的文章中一些内容是错误的。此前杂志刊文称，叶诗文的表现是异常的，即使当前的药检结果清白，也不能完全排除服用兴奋剂的可能;对此烤鸭们可以作为一篇雅思阅读，提高成绩的同时了解外媒那种扭曲的病态心态。

　　Why great Olympic feats raise suspicions

　　At the Olympics, how fast is too fast? That question has dogged Chinese swimmer Ye Shiwen after the 16-year-old shattered the world record in the womens 400-metre individual medley on Saturday. In the wake of that race, some swimming experts wondered whether Yes win was aided by performance-enhancing drugs. She has never tested positive for a banned substance and the International Olympic Committee on Tuesday declared that her post-race test was clean. The resulting debate has been tinged with racial and political undertones, but little science. Nature examines whether and how an athletes performance history and the limits of human physiology could be used to catch dopers.

　　Was Yes performance anomalous?

　　Yes. Her time in the 400 IM was more than 7 seconds faster than her time in the same event at a major meet in July. But what really raised eyebrows was her showing in the last 50 metres, which she swam faster than US swimmer Ryan Lochte did when he won gold in the mens 400 IM on Saturday, with the second-fastest time ever for that event.
