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。

Reading 1THE EARTH IS BECOMING WARMER — BUT DOES IT MATTER During the 20th century the temperature of the earth rose about one degree Fahrenheit. That probably does not seem much to you or me, but it is a rapid increase when compared to other natural changes. So how has this come about and does it matter Earth Care's Sophie Armstrong explores these questions.There is no doubt that the earth is becoming warmer (see Graph 1) and that it is human activity that has caused this global warming rather than a random but natural phenomenon.All scientists subscribe to the view that the increase in the earth's temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy. Some byproducts of this process are called "greenhouse" gases, the most important one of which is carbon dioxide. Dr Janice Foster explains: "There is a natural phenomenon that scientists call the 'greenhouse effect'. This is when small amounts of gases in the atmosphere, like carbon dioxide, methane and water vapour, trap heat from the sun and therefore warm the earth. Without the "greenhouse effect', the earth would be about thirty-three degrees Celsius cooler than it is. So, we need those gases. The problem begins when we add huge quantities of extra carbon dioxide into the atmosphere. It means that more heat energy tends to be trapped in the atmosphere causing the global temperature to go up." We know that the levels of carbon dioxide have increased greatly over the last 100 to 150 years. It was a scientist called Charles Keeling, who made accurate measurements of the amount of carbon dioxide in the atmosphere from 1957 to 1997. He found that between these years the carbon dioxide in the atmosphere went up from around 315 parts to around 370 parts per million (see Graph 2).All scientists accept this data. They also agree that it is the burning of more and more fossil fuels that has resulted in this increase in carbon dioxide. So how high will the temperature increase go Dr Janice Foster says that over the next 100 years the amount of warming could be as low as 1 to 1,5 degrees Celsius, but it could be as high as 5 degrees.However, the attitude of scientists towards this rise is completely different. On the one hand, Dr Foster thinks that the trend which increases the temperature by 5 degrees would be a catastrophe. She says, "We can't predict the climate well enough to know what to expect, but it could be very serious." Others who agree with her think there may be a rise of several metres in the sea level, or predict severe storms, floods, droughts, famines, the spread of diseases and the disappearance of species. On the other hand, there are those, like George Hambley, who are opposed to this view, believe that we should not worry about high levels of carbon dioxide in the air. They predict that any warming will be mild with few bad environmentalconsequences. In fact, Hambley states, "More carbon dioxide is actually a positive thing. It will make plants grow quicker; crops will produce more; it will encourage a greater range of animals —all of which will make life for human beings better." Greenhouse gases continue to build up in the atmosphere. Even if we start reducing the amount of carbon dioxide and other greenhouse gases, the climate is going to keep on warming for decades or centuries. No one knows the effects of global warming. Does that mean we should do nothing Or, are the risks too great第四单元全球在变暖全球在变暖一一这会带来什么影响吗在20世纪期间,地球温度大约升了华氏1度。
