Unit 4 Global Warming 教学设计1-公开课-优质课(人教选修6精品)

Unit 4 Global warming教学案1教材分析Ⅰ.教学内容分析本单元的中心话题是人类当今面对的环境问题，主要探讨了“全球变暖”和“节约能源”等方面的问题。

由于人类过多使用不可再生能源，大气中二氧化碳的含量逐年增加，导致全球气温上升。

通过学习本单元，让学生了解能源分为“不可再生能源”和“可再生能源”，帮助学生树立“节约能源、保护环境”的主人翁意识。

语言知识和语言技能主要围绕“全球变暖”和“节约能源”这一主题设计的。

“热身”(Warming up) 部分要求学生列举家中、学校或其他地方使用能源的物体，指出这些能源的来源，并尽可能多地列举不同的能源。

能源可分为两类：一类是可再利用能源；另一类是一次性能源。

把前面列举的能源按能否再利用这一标准进行分类。

本部分提供了六幅图片，教师可以从识图开始组织教学。

还可以让学生搜集一些其他相关图片。

这六幅图分别为：风力（wind power）、燃煤发电站（a coal power station）、炼油厂（an oil refinery）、原子能发电站（a nuclear power plant）、太阳能接受器（solar panels）、水坝（a hydro dam）。

“读前”(Pre-reading) 部分首先介绍什么是温室、它有什么作用，然后要求学生讨论大气中温室气体的作用。

温室是由玻璃构成的建筑，主要用于花果蔬菜的培植。

温室能阻止热量散发，因而能帮助植物度过寒冷的时期。

该部分的讨论有利于学生预测课文内容和理解阅读课文中的温室气体效应。

“阅读”(Reading) 部分是一篇杂志文章，主要讲述了地球温度上升的现象和原因。

20世纪中，地球的温度上升了华氏1度。

这看上去是一个很小的数字，但相对于自然界的其他现象来说，这个增长速度是迅猛的。

这种现象是自然发生的还是人为的？这个问题引起激烈的争论。

许多科学家认为，这种变化是人类燃烧矿物燃料所致。
