SectionD
Ⅰ.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。

不然会造成冷场。
