让学生了解奥运精神，也进一步使学生了解运动员服用兴奋剂对其身体健康的负面影响；学习和认识真实条件句和非真实条件句及其运用并复习了介词的用法；学习征求意见和给出建议的表达，使学生能够正确运用征求意见和给出建议的句式；学会用正确的方法合理安排文章的前后顺序，使其结构严谨，层次分明；设计了书写文章所需运用的常见连接词；通过对文化角的学习使学生了解我们国家的传统医学和传统文化; 通过讨论遗传工程，过度到一种新的听说策略，使学生通过学习这种策略能够较好完成讨论任务；设计lance armstrong的故事在语法上使学生练习了情态动词的用法，了解lance armstrong的经历会使学生意识到生活和学习中我们需要有自己的人生目标，遇到困难我们要坚持不懈,最终我们一定会实现自己的目标；安排综合评价课要求学生对已学知识掌握的情况进行自我了解和自我评定，训练他们的表达能力和概括能力；要求他们通过回答问题来确定自己学习英语的方法实用与否并自己安排阅读下一本英语书的计划。1.1 warm-up是本单元的热身活动，它利用图画形式向学生介绍了人体一些重要部位的表达及其功能，引导学生重视和养成健康的生活习惯，也为下一块lesson 1 super athletes 做出铺垫。1.2 lesson 1 super athletes包括9项活动，其中13项的设置紧扣文章内容。第一项设置了与体育比赛有一定联系的问题，要求学生根据实际情况做出客观回答并预测课文内容。第二项是要求学生阅读课文来训练他们的理解能力并考查学生捕捉文章重点信息的能力。第三项的内容是在前一项的基础上深入到文章的其他的信息，从而使学生对整篇内容的结构和层次有全面了解和掌握。所有这些在另外一方面是为了引导学生正确理解奥运精神。第四至第九项是关于真实条件句和非真实条件句的认识和运用。1.3 lesson 2 brain power 包括8项活动, 第一项中出现listening strategies 通过四个步骤来要求和规范学生, 使得他们能够较好把握听力内容；第二、三项是训练学生的听的能力；第四项通过安排热线电话节目在训练学生听力的同时给出他们一些关于考前复习的建议；第五项学习怎样正确地征求意见和给出建议，使学生能够运用征求意见和给出建议的正确句式；第六项设计四种情况来训练学生的写的能力；第七项要求学生掌握一些常见的动词短语及其运用；第八项是培养学生的读写能力。1.4 lesson 3 epidemics explained也包括8项活动,第一项的设计使学生初步学习流行病的表达；第二项中出现reading strategies 通过四个步骤训练学生对于所给出的信息排序；第三项学会用第二项中出现的阅读策略正确而合理地安排文章的前后顺序，使其条理清晰；第四和第五项的设计是训练学生的理解能力和表达能力；第六项中通过同义词的练习进一步拓展了学生的词汇量；第七项的设计是为了巩固和加强学生对文中词汇的掌握；第八项要求学生运用他们的想象力来表达出他们对于未来的期望。1.5 communication workshop由writing, listening和speaking三部分组成，writing部分通过对一案件审判结果的讨论，在练习1和练习3中设计了书写此类文体所需运用的常见连接词；在练习2中要求学生理清四段文字的框架；随后又给出“是否该禁烟”的主题要求学生按四个步骤选定自己的观点并写一篇小短文。reading中安排专家讨论问题的电视节目，多人物、多角度地训练和提高学生听力。speaking部分前三块安排就遗传工程进行的讨论，从而过渡到一种新的听说策略，使学生通过学习这种策略能够较好完成讨论任务。1.6 language awareness 6部分通过安排lance armstrong的故事,在语法上练习了情态动词的用法。此外，学生在阅读完文章了解lance armstrong的经历后，他们会意识到生活和学习中我们需要有自己的人生目标，遇到困难我们要坚持不懈,最终我们一定会实现自己的目标。 1.7 culture corner部分主要向学生介绍了我们国家的传统医学,通过学习既使学生进一步了解我们国家的传统医学又培养了学生的综合运用语言的能力。1.8 unit diary部分设计了十一项内容。第一项是了解本单元学生最喜欢的课文；第二项要求学生对已学知识掌握情况的自我了解和自我评定；第三项至第八项的设置是安排学生对本单元细节的自我检测以及训练他们的表达能力；第九至第十项是针对新单词这一块要求学生进行自我评定；第十一项的设计是开拓学生的视野，要求他们通过回答问题来确定自己学习英语的方法适用与否并自己安排阅读下一本英语书的计划。2. 材料重组2.1 warm-up 是本单元的导入部分，可以和1. super athletes（1-3）部分结合成整体，设计为一节“阅读课”。2.2 将1. super athletes（4-9）部分和workbook中1. super athletes（1-5）部分、workbook中prepositions部分以及workbook中 remember部分结合在一处，设计成“语法知识课（一）”。2.3 将2.brain power部分和workbook中2.brain power部分整和在
