Unit 5 Humans and Nature Period One（教师用书Word）-【状元桥·优质课堂】2023-2024学年新教材高中英语必修第二册（北师大版2019）

❶As we all know, thousands of animal species become extinct every year. Some wild animals are disappearing from our planet forever at a surprising speed①. Scientists estimate② 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 ever③. 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 up④ a biological community—an ecosystem—in which each part depends on another for survival. When one part of the community is thrown off-balance(不平衡地) 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 immediate⑤ attention and action. ❷Through 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: Respect⑥ and protect the earth's wildlife. 【词块采撷】 ①at a surprising speed　以惊人的速度 ②estimate v．估计；判断 ③faster than ever 比以往更快 ④make up 组成；化妆；编造 ⑤immediate adj.立刻的；即时的 ⑥respect v．&n.尊重；尊敬；敬重 【亮句应用】 ❶as引导的定语从句 (2022·北京)But as some researchers find, the food system is not an equal one.但正如一些研究人员发现的那样，食物系统并不平等。 ❷动名词短语作介词宾语 (2022·全国甲)Inspired by the Belt and Road Forum for International Cooperation held in Beijing, Cao decided to cover the route by hiking as a tribute (致敬) to the ancient Silk Road. 受到在北京举行的“一带一路”国际合作高峰论坛的启发，曹决定徒步穿越这条路线，以向古代丝绸之路致敬。 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。 Period One　Topic Talk & Lesson 1—Comprehending [教材
