Unit4AmazingScienceTopic2I’mexcitedaboutthethingsthatwillbediscoveredinthefuture.SectionDⅠ.Materialanalysis本课是九年级第四单元第二话题的第四课时。主活动是1a和Project。“语法和功能”部分让学生总结归纳一般将来时的被动语态。1a继续学习宇宙知识并讲述了人类探索宇宙的活动。在这个部分还留下了一个悬念：茫茫的宇宙中还有其他生命存在吗？很好地激发了学生探索宇宙的欲望。1b这个图表型的任务可以看作是一个跨学科衔接。地理知识好，不用看1a也能完成，否则必须把1a读懂才能完成。3是个有趣的活动。学生在展开想象的同时可以顺便复习将来时的被动语态。本课的Project不再是写作任务，而是口语活动任务。以学生现有的知识不难完成此任务。2是个写作任务，让学生描写“地球”。由于写作需要较长的时间，故把2留作家庭作业。Ⅱ.Teachingaims1.Knowledgeaims：掌握本课的重点词汇和短语，了解太阳系的相关知识。2.Skillaims:能够通过“语法和功能”部分，把被动语态进行系统地整理。能够借助1a的插图和文字，对太阳系有比较清晰的了解。3.Emotionalaims:(optional)激发学生探索宇宙的兴趣。
4.Cultureawareness:(optional)Ⅲ.Thekeypointsanddifficultpoints1.Keypoints:Wordsandphrases:launch,beyond,send…to…Sentences:Thesunanditsplanetsarecalledthesolarsystem.Somespaceshipshavegonebeyondthesolarsystem.Grammar:sumupfuturepassivevoiceDifficultpoints：Withsomanystarsinspace,arewealone,oristherelifeonotherplanetsinspace?Ⅳ.Learningstrategies学会梳理和总结归纳已学知识以便更好地记忆、理解和使用。如：总结所学过的所有被动语态。能够通过课文的插图帮助理解课文。在做Project的时候，要敢于积极发言，专注于表意，不要怕出错。Ⅴ.Teachingaids火箭发射的视频/太阳系的图片/ppt等。
