Find more ways to protect the Earth on the Internet.Teaching aids 教学准备（含板书设计）教学准备：PPT 课件、图字卡。板书设计：Unit 7 Protect the EarthTo protect the Earth, we should To protect the Earth, we should not 说课本课是练习和复习课，首先让学生在复习前面所学生词的基础上进行讨论，以此来练习前面所学的句型。同时也为下一步教授新句型打好基础。相比起直接告诉学生汉语，让学生在语境中理解和运用目标句型会更有效，同时也避免了学生用汉语思维学习英语的情况。学习过新句型后，我设计了一个游戏，让学生从包中随意拿出一个东西说出如何再利用，激活学生思维的同时也让学生把书本中所学的知识运用到现实生活中来。然后通过已学的 What should do?句型引到 What should not do?句型上。让学生观看现实生活的视频后给出建议，练习本单元目标句型。最后把学生给出的句子组合在一起，形成一个完整的海报，使学生感知如何制作海报。
