ndphrasesbyheart.2.Trytowriteaproposal(倡议)onhowtoliveagreenlife.教学效果：本课时主要学习如何用英语表达保护环境，但课本上所设计到的环保生

活方式很有限，为了让学生能够更多的说环保的话题，并且培养他们的环保意识，练习活动中设计了谈论活动，让学生想出更多有关环保的生活细节。同时，老师还给归纳出更多绿色生活方式与同学们分享。最后，调查问卷的提问更真实

让学生深入进环保生活情境，因为很多学生之前能够想到要节约用纸，但被问及白纸是否会反面也使用时很多同学都感到惭愧，他们很少将白纸的反面使用，同时有学生试着说出以后生活中会弥补这已不足。所以，本节课从整体上感知对学生的拓展环保意识教育还是很有成效的。
