由于它是影响力大的欺骗形式，体育界是不会容忍运动员服 用兴奋剂的。本·约翰逊如果在1988年奥运会上没有被查出服用兴 奋剂的话，今天他还可能是百米世界纪录的保持者。其他一些短 跑纪录至今依然让人感到怀疑。比如，弗洛伦斯·格丽菲斯1988年 的百米纪录。她服兴奋剂了吗？如果美国运动员玛里昂·琼斯没有 服用兴奋剂的话，她能成功地进军奥运会吗？
服用兴奋剂不仅仅是田径运动存在的问题，每个运动项目都 存在这个问题，运动员设法取得超常体育成绩而准备欺骗。当 2006年环法自行车赛的冠军、名将弗洛伊德·兰蒂斯被查出服用了 兴奋剂时，举世为之哗然。弗洛伊德·兰蒂斯做了几次站不住脚的 辩解，责怪他因伤服用的药物，但是这些都是徒劳的。他的两次 兴奋剂检测结果都呈阳性。
谈到破纪录，我们就会碰到服用提高成绩的药物问题。研制 这些药物原本是用来帮助人们解除病痛的，但误用到运动员身 上，就会使他们在竞技比赛中超乎寻常地发挥，变得更快、更 强。服用这些药叫做“服兴奋剂”。尽管服兴奋剂有助于提高成 绩，但同时也会给那些滥用兴奋剂的运动员在日后生活中带来严 重的健康问题。
④The sports world does not tolerate doping as it is a fundamental form of cheating. Ben Johnson would still be the 100 metres world record holder if he had not been caught taking drugs in the 1988 Olympics. Other records remain doubtful, like Florence Griffith's 100 metres record back in 1988. Did she take drugs? If American athlete Marion Jones hadn't taken drugs, would she have made it to the Olympics at all？

Unit21 Lesson 1参考教案3 periodsTeaching Objectives:1. To read about athletes, doping and geneetherapy.2. To get the students to sume up the general idea of the text3. To practise using mixed conditionalsTeaching Difficult & Important Points:1. To get the students to sume up the general idea of the text2. To use the mixed conditionalsTeaching Facilities: multimedium, photos, tapeTeaching Procedures:Step 1. Pre-readingSay: I know some of you quite like sports and even are the fans of some stars. In a common sense, it is not so bad. But what champion athletes can you name? What were their achievements?(Get reports from the students’ discussion.)Step 2. While-readingI. Read the text quickly. What is the general idea? Answer: c)II. Pairwork. Answer the questions of Ex.3. Answers:① Athletes are stronger and faster today than they were during the time of the first Olympic Games.② Better equipment, training and diet.③ Doping is using performance-enhancing drugs and it is illegal because it is cheating.④ Ben Johnson was caught taking drugs when he broke the 100m world record in 1988 and no one knows if Florence Griffith was taking drugs when she set the women’s 100m record the same year.⑤ Drug tests are only developed after the new drugs are being used. This means that there is a time period when people are using the new drugs and no one knows about them.⑥ It would create super athletes who could do the 100m in just 8 seconds for example, and no one would know if they’d had gene-therapy or not. This would spoil the spirit of sport.⑦ The spirit of competition that emphasizes talking part rather than winning.III. Language Points:1. slow down减速，放慢速度You must slow down your car. 你必须把车子开慢。

From Argentina to Zambia ， Regina Guthold of the World Health Organization in Geneva and her colleagues found most children aren't getting enough exercise and it made no difference if they lived in a rich or a poor country. “With regards to physical activity levels，we did not find much of a difference between poor and rich countries，”Guthold said.
