A
The researchers’ findings will hardly come as a surprise to those who study air
pollution. Previous research has shown that outdoor air pollution causes more than 3
million deaths annually and suggested that the figure could double by 2050.
Another study suggested that air pollution causes 1. 6 million premature(早产儿)deaths annually in China alone. Policy makers across the globe have responded to
air pollution with a number of new regulations, many of which focus on limiting
pollution from coal. China stopped approval of new coal mines for three years at the end

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。这些物质的燃烧产生以二氧化碳为主的温室气体。正因为自然界有温室气体的存在,地球才不至于很冷。但大量排放二氧化碳会使地球普遍升温。对于地球升温,科学家有不同的看法。有些科学家认为,这个问题很严重。地球升温会导致海水上涨、风暴、干旱、饥荒、物种毁灭和疫病等。也有科学家认为,地球升温有利于改善人类生活,比如,庄稼长得更快、产量更高等。文章最后以开放性的问题结尾要求读者思考:对于全球变暖,人类要不要采取措施?
