本考点源自Unit 8 “Our Blue Planet”。地球是人类共同的家园，但环境污染越来越严重。我们应该怎样保护地球？本讲将带你学习与环保相关的核心词汇和短语，并掌握如何用英语表达环保行动。
一个小故事：
小明看到河边有很多塑料瓶和垃圾，河水又脏又臭。他很伤心，对妈妈说：“The river is polluted. We must protect the environment.” 妈妈点点头：“Yes. We should save water, recycle waste, and plant more trees. Every small action helps.” 从那以后，小明每天关水龙头、垃圾分类，还和同学们一起植树。他的行动虽然小，但让环境变得更美好了。
