But do you kno w that many of the environmental problems our country faces today result fro m our fossil fuel dependence.The environment faces air pollution, global warming, acid rain, and several oth er very serious problems because of our use of fossil fuels. Over the last 150 years, burning of fossil fuels has resulted in more than 25 percent increase in carbon dioxide in our atmosphere.Carbon dioxide is one of the main factors in global warming which is negativ ely affecting everyone.Fossil fuels also affect water pollution, land pollution, and thermal pollution (h eat pollution). Coal mining is one of the causes of pollution in the environmen t. After the mining is completed, the land will remain barren. Materials other t han coal are also brought to the surface in the coal mining process and these are left as solid wastes.The production, transportation, and use of fossil fuels are to blame for the effe cts of pollution on the environment. Then what should we do? We should spar e no effort to improve our environment. Please save energy and use fewer fos sil fuels in our daily lives.Step 4 HomeworkFinish your composition on environmental problems.。

说课稿Unit4 Global warming----The earth is becoming warmer-but does it matter?本节课是高中英语新课标选修6第4单元的课文阅读课，课文标题为“the earth is becoming warmer-but does it matter?” 这个单元的课题global warming 是一个具有非常现实意义的话题，因为全球变暖已经是一个非常严峻的问题，而且日渐得到全世界的瞩目和关注，因为它关系着地球和人类的未来命运。

因此全球变暖是如何产生的，它对人类和地球未来究竟有何影响，我们该如何应对这个问题是我们当代中学生应该了解的，这也正是这一节课的课文内容。

这堂课有四个教学目标，一是阅读和理解课文主旨内容，使学生了解什么是全球变暖，它是如何产生的，二是找出每一段的段落大意，三是理解课文的细节信息，最后是让学生能运用所学内容进行讨论-whether we should do something about global warming. 这堂课的教学重点在于指导学生多层次阅读，理解和掌握课文内容，完成阅读任务，教学难点在于指导学生对课文阅读内容进行整合，再利用其进行口头讨论，表达和支持自己观点。

整堂课以阅读理解为主，听说为辅。

在这里，我特别想提出的是一个我一贯坚持的做法，那就是借助中学生双语报b版上的课文理解部分及课文链接部分作为有效教学资源，辅助课堂阅读教学，提高教学效果。

有经验的老师也知道，阅读教学过程中，教师必须给学生设置由易到难，由快到慢的阅读任务，才可达到较佳的阅读效果，同时也对学生进行了任务型阅读训练，让他们的阅读能力逐步提高，从而训练并提高其高考应试能力。

因此，好的阅读任务的设定就至关重要了。

我在长期的教学中发现除了现有的教材之外，众多的教辅资源是教材的有效补充，而另外课文链接部分则真正是教材课文内容的有效链接，极大地扩大了学生的阅读量和阅读面。

Unit4 Global warming一、学生分析本堂课所教学生为高二文科班的学生，积极和活跃是他们在课堂学习实践活动中的特点。

大部分学生经过初中和高一阶段对英语这门语言的学习和掌握，已经为高二阶段的英语学习打下了较好的基础。

表现为：大部分学生能够做到课前预习和准备，课堂上能伴随课程的思路，积极主动的参与课堂活动，如小组讨论，问答练习等；并且部分学生都具有一定的自我约束能力和独立思考的能力，如对某一问题进行讨论时除了能够完成对问题的回答，还能够提出反问甚至是自己独特的见解等。

但是仍有一小部分学生由于种种原因造成了英语基础薄弱，上课不够积极主动，学习任务完成不充分等问题。

对此，在课堂活动中要进行有针对性的帮助。

如进行分组讨论时，可让他们与学习基础好的同学一组且要给予更多的鼓励，使他们尽早能提高对学习英语的兴趣。

本堂课之前学生们已经完成了对Model 6 Unit3 A healthy life 的学习任务，对健康生活的真正涵义也有了一定的理解。

因而在本堂课的引入环节中就结合这个内容进行了设问。

如“健康生活需不需要保护环境呢？”等。

且学生在这一单元以及之前所掌握的英语语言知识技能如：环境和健康的关系；如何开展讨论；如何发表自己的观点等都可以运用到本节课中。

二、本节课教材分析与教材整合1. 单元教材分析本单元以Global warming 为主题，学生通过单元教学经过思考、学习，讨论从而认识到全球变暖的真正涵义和它所带来的种种后果。

同时学生能够进一步认识我们的地球所面临的其它严重问题，激发学生的环保意识。

引导学生运用所学语言知识、句式表达自己对这些现象的看法，培养他们为自己的观点辩论的能力。

Warming Up通过真实的图片再现，使学生对能源的用途和种类有一个基本的了解。

从而为本单元主题Global warming 作了很好的铺垫。

Pre-reading部分组织学生对这些问题的讨论、回答，也让学生有进一步思考的空间，为下一步阅读做好准备。

Unit 4Global warming错误!本单元的中心话题是人类当今面临的环境问题，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。

Period 1Warming Up,Pre－reading，Reading and Comprehending错误!教学内容分析This is the first teaching period of this unit.The central part of this period is the reading passage with the title of “The Earth Is Becoming Warmer—But Does It Matter？” talking about the global issue which has a great effect on human beings' life。

Warming Up gives six pictures to help students list the sources of energy they can think of in our daily life。

Then they will be led to discuss which energy source is “renewable” and which is “non－renewable”．This part is designed to help the students to recall their background knowledge about energy and prepares students for the whole unit。
