英语必修第二册课堂学案(BS】 UNIT 5 HUMANS AND NATURE =··阅读美文激活思维 ● o As we all know,thousands of animal species become extinct every year. Some wild animals are disappearing from our planet forever at a surprising speed.Scientists estimate that the current rate of extinction is thousands of times greater than it would normally be because of one factor-humans.We are consuming the earth's natural resources faster than ever.We destroy animals'habitats,food,water and air,as well as the animals themselves. We may consider the animal world to be separate from our own,but in fact,our lives and theirs are connected in several aspects.Plants,animals,people and the environment together make up a biological community-an ecosystem-in which each part depends on another for survival.When one part of the community is thrown off-balance()or disappears,the entire system will suffer. We may not be able to bring back the species we have already lost,but many others on the edge of extinction need our immediate attention and action.Through cutting demands for animal byproducts,.introducing laws against trafficking(非法贩卖)，and volunteering in organizations that help protect endangered species,people fight with the threats the earth's wild animals are faced with. No act of protection is too small.Be the solution:Respect and protect the earth's wildlife. 【词块采撷】 food system is not an equal one..但正如一些研究 ①at a surprising speed以惊人的速度 人员发现的那样，食物系统并不平等。 ②estimate u.估计：判断 ②动名词短语作介词宾语 ③faster than ever 比以往更快 (2o22·全国甲)Inspired by the Belt and Road ④make up 组成：化妆：编造 Forum for International Cooperation held in ⑤immediate adj.立刻的：即时的 Beijing,Cao decided to cover the route by hiking ⑥respect u.&n尊重：尊敬：敬重 as a tribute(致敬)to the ancient Silk Road. 【亮句应用】 受到在北京举行的“一带一路”国际合作高峰论 ①as引导的定语从句 坛的启发，曹决定徒步穿越这条路线，以向古代 (2o22·北京)But as some researchers find,the 丝绸之路致敬。 。核心素养立德树人● 语言技能：①熟练运用本单元词汇以及句式：②学习定语从句(2)、后缀：③学习灾难求生的文章，学会 如何在灾难中求生。 素养提升：①了解不同国家的自然景观、欣赏有关大自然的影视作品：②感受自然的力量、了解人对自 然的探索以及学会如何实现人与大自然的和谐相处。 ·32 UNIT 5 HUMANS AND
