UNIT 3 ENVIRONMENTAL PROTECTION单元分析本单元主题：人与自然单元内容分析本单元围绕“环境保护”这一主题展开。

大自然为人类提供了生存的环境，如果环境遭受破坏，那么人类生存发展的空间就会被破坏，所以保护环境就是保护人类自己。

保护环境可以促进经济发展，尤其是促进经济的可持续发展。

环境保护体现了个人修养与素质，是社会文明进步的标志。

以下为教材各部分教学内容简要分析及教学活动实施建议：1．Opening Page：主题图呈现的是处于融化状态的冰川。

全世界冰川融化导致的海平面上升是最令人担忧的气候变暖的后果之一。

一些低海拔的地区很可能会被海水吞没，生活在这些地区的人和动物也会遭受危害。

开篇页的引言“Earth provides enough to satisfy every man＇s needs，but not every man＇s greed.”出自印度国父甘地，意为“地球所提供的物质财富足以满足每个人的需求，却不足以满足每个人的贪欲。

”地球是人类生活的家园，人类的生存和发展必须依赖自然环境和自然资源。

因为贪婪，人类过度开采自然资源，造成环境破坏、生态失衡、资源枯竭，最终受害的还是人类自己。

人类只有坚持科学发展观，适度利用资源，我们生存的环境才会逐渐改善。

2．Reading and Thinking：该板块以“讨论气候变化”（Discuss cimate change）为活动主题，引导学生探讨全球气候变暖的表现、原因、后果以及需要采取的应对措施。

改变自己的生活方式以减少碳排放，对公众进行相关的宣传教育，这是生活在地球上的个体可以采取的行动。

通过完成阅读理解活动，学生可以了解极端气候变化背后的成因，认识人类活动对全球气候产生的巨大影响，反思自己的行为，进而懂得如何减缓气候变暖的进程，从自身做起，成为有责任和担当的人。

3．Learning About Language：该部分分为两个板块：“Build up your vocabulary”和“Discover useful structures”。
