Unit4Topic2SectionC教学设计Ⅰ.Materialanalysis本课是九年级第四单元第二话题的第三课时。主活动是1a。1a是承接SectionA和SectionB设计的。因为在这两个Section里总是提

到Mars，学生已经对它产生了兴趣。“宇宙”属于“自然”的一部分。而“自然”正是课程标准要求的话题。1b属于理解型任务，学生如果能独立完成表格，也就说明他们已经掌握了1a的内容。1c看似让学生讨论，其实通过学习1a,学生都能对所给的问题作出正确的判断。2这个任务是为3a

和3b作铺垫。学生通过学习本课，可以对火星有大致的了解，也有助于激发学生探索宇宙的好奇心。3a和3b这两个任务关联性很强，3b只有在学生完成了3a之后才能完成，没有3a的信息，3b就不能进行。把这两个任务留作家庭作业较好。Ⅱ.Teachingaims1.Kno

wledgeaims：掌握本课的重点词汇和短语，了解火星的相关知识。2.Skillaims:能够通过所获取的文字信息，对火星有所了解，拓展自己的知识面。3.Emotionalaims:(optional

)激发学生探索宇宙的兴趣。4.Cultureawareness:(optional)Ⅲ.Thekeypointsanddifficultpoints1.Keypoints:Wordsandphrases:storm,weigh,journey,excitement
