英语必修第三册课堂学案(BS】 UNIT 8 GREEN LIVING -··阅读美文激活思维 ● Once man did not have to think about the protection of his environment.There were few people on the earth,and natural resources seemed to be unlimited. Today things are different.The world has become too crowded.We are using up our natural resources,and polluting our environment with dangerous chemicals.If we continue to do this,human life on earth will not survive. We realize that if too many fish are taken from the sea.there will soon be none left.Yet,with modern fishing methods,more and more fish are caught.We know that if too many trees are cut down,forests will disappear.Yet,we continue to use powerful machines to cut down more and more trees.We see that if rivers are polluted with waste products,we will die.Yet,waste products are still put into rivers.We know that if the population continues to rise at the present rate,in a few years, there won't be enough food.What can we do to solve these problems? If we eat more vegetables and less meat,there will be more food available.Land for crops feeds five times more people than landwhere animals are kept.Our natural resources will last longer if we learn to recyele them.The world population will not rise so quickly if people use modern methods of birth control. Finally,if we educate people to think about the problems,we shall have a better and cleaner planet in the future. 【词块采撷】 individuals.例如，从4个5人的讨论小组中得到 ①use up 用完：耗尽 的平均值比从20个独立个体中得到的平均值要 ②available adj.可用的：有空的 准确得多。 ③recycle .回收利用，再利用 ②where引导定语从句 【亮句应用】 (2o23·全国乙)Born to a Jewish family in ①过去分词作定语 Florence,she moved to Paris where she worked (2023·新高考I)For instance,the average as a physician and performed surgery. obtained from the estimates of four discussion 她出生在佛罗伦萨的一个犹太家庭，后来搬到了 groups of five was significantly more accurate 巴黎，在那里她成为了一名内科医生，并从事外 than the average obtained from 20 independent 科手术。 =●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学习动词-ing形式和-ed形式：③学会写调查报告：④学 会用自己的方式去保护环境。 素养提升：①了解“根与芽”组织及其宗旨：②了解环境问题，增强环保意识，
