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。

[精美语篇]It is said that sports is an important form of life. Sports can help everyone keep healthy, enrich our life and maintain our psychological health, and help us relax after a period of exhausting work. A person who often takes exercise is always full of energy. Sports can also make people look younger than they really are. What's more, it produces chances to train our intelligence. Because we think actively when we do exercise.My participation in sports tells me that sports can make us healthy both physically and psychologically. It is also a good way for people to know each other and can promote friendship between people. So long as we are careful enough, sports can do us nothing but good.Personally, I love sports. I enjoy participating in sports. I feel that I not only gain a well-balanced life through sports, but also get more chances to move closer to nature. Sports have really added happiness to my daily life.高频单词1．tolerate (vt.) 容忍→tolerant (adj.) 容忍的；宽容的→tolerance (n.) 容忍；忍受2．fundamental (adj.) 根本的，基础的3．seek (vt.) 寻找→seeker (n.) 寻找者；追求者4．oppose (vt.) 反对→opposition (n.) 反方；对立面→opposite (adj.) 相反的；对面的→opposed (adj.) 反对的5．violate (vt.) 违反；违背→violent (adj.) 猛烈的→violence (n.) 暴力6．postpone (vt.) 推迟，延期7．prohibit (vt.) 禁止→prohibition (n.) 禁止8．faith (n.) 信心→faithful (adj.) 忠诚的；忠实的→faithfully(adv.) 忠诚地9．rob (vt.) 使丧失；抢劫→robber (n.) 强盗→robbery (n.) 盗窃10．decline (vi.) 下降 (n.)减少；下降；衰减11．minimum (n.) 最低，最小→maximum (n.) 最高，最大12．equip (vt.) 使有准备→equipment (n.) 设备；装备13．fortune (n.) 大笔钱财，巨款；运气→fortunate (adj.) 幸运的→fortunately (adv.) 幸运地14．enquiry (n.) 询问→enquire (vt.) 询问；调查15．submit (vt.) 提交→submission (n.) 提交16．extension (n.) 延期→extend (v.) 延长17．concern (n.) 担心；担忧→concerned (adj.) 关心的；担忧的→concerning (prep.) 关于；有关18．circumstance (n.) 情形；情况重点短语1．at_all_costs 不管多大代价；无论如何2．straight_away 立刻；马上3．in_vain 徒然；白费力气4．at_random 随便地；随意地5．wipe_out 彻底消失6．stop_sth._in_its_tracks 终止；消灭7．at_any_rate 无论如何；至少8．bring up 教育；养育；呕吐；引述9．go through 经历；通过10．put off 推迟11．get down to 开始做12．get through 通过(考试等)；完成13．focus on 聚集；集中；对准14．for good (and all) 长期地；永远地15．miss out 遗漏；遗忘；错过机会热点句型。
