仁爱版八下教案Unit 6 Topic 3 Bicycle riding is good exercise 第4课时

Unit6EnjoyingCyclingTopic3Bicycleridingisgoodexercise.教学内容分析及课时分配建议：本话题围绕自行车而展开。主要内容包括：孩子们由一次交通事故展开讨论,引出语法项目“条件状语从句”和话题“骑自行车”。通过图片展示自行车交通事故，引出避免交通事故的一些建议，不遵守交通规则可能带来的危害及制定合理的骑行规则。最后为了拓展学生的视野，学习环青海湖自行车赛和环法自行车赛。通过学习本话题，可以增强学生的安全意识，激励学生热爱自行车运动，倡导“绿色出行，低碳出行”的理念。本话题建议用5个课时来完成：第一课时：SectionA—1a,1b,1c,1d,2第二课时：SectionA—3a,3bSectionB—1a,1b,2a,2b第三课时：SectionB—3a,3bSectionC—1a,1b,1c第四课时：SectionC—2,3SectionD—2第五课时：SectionD—GrammarandFunctions,1,Project第四课时（SectionC—2,3SectionD—2）教学设计思路：本课是一节写作课。一篇是有关骑自行车，以此为主；另一篇是根据事故报告单改写故事，以此为辅。在本课中，把写作分成写前，写中和写后三个部分。首先让学生看图复习条件状语从句和提建议并快速完成SectionC-2的词汇练习，接着便转入写前的词汇、句子准备环节。接着让学生独立写作，进入写中环节。待学生写完以后，先在组内互评，然后择优在班内展示。完成了SectionC-3的主要写作任务后，转入SectionD-2的改写任务。因为在SectionA-3a已经进行过类似的写作，完成该任务相对比较容易，故老师只要展示一篇范文供学生参考即可。最后总结写作的步骤，布置家庭作业完成本课。本课主要Ⅰ.Teachingaims1.Knowledgeaims：（1）学习并掌握新词汇
