仁爱版八下教案Unit 6 Topic 3 Bicycle riding is good exercise 第3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第三课时（SectionB—3a,3bSectionC—1a,1b,1c）教学设计思路：本课主要继续学习条件状语从句和交通规则。首先结合条件状语从句来操练句子的重读完成3a和3b，完成3a和3b，让学生体会不同的重读表达不同的含义。本课是阅读课，分为泛读和精读两个层次。在Pre-reading，先通过图片等解决词汇障碍。泛读是为了培养学生概括文段大意的能力,读完1a后先完成1b。然后让学生进行精读，寻找特定的信息完成1c。Post-reading部分让学生进行字词的学习。再通过挖空复述课文的方式完成本课时。Ⅰ.Teachingaims1.Knowledgeaims：（1）学习并掌握新词汇safety,truck,notice,injury,signal,payattentionto,incaseof,firstaid,inaword,lookout（2）继续学习if引导的条件状语从句2.Skillaims:（1）能够归纳各段落的中心句。（2）能够总结短文的主旨。（3）能够根据说话者的语气来理解说话者的意图。3.Emotionalaims:
