高三英语专题复习 Unit 2 The environment（第4课时）教案教学过程Forth periodProject 1: Protecting the Yangtze RiverAs the third longest river in the world, the health of the Yangtze River has raised concern both in China and abroad. Rapid development and an increase in population have meant that the amount of water taken from the river is rising, and the waste being put back into the river has been increasing. This is not good news for the people who rely on the Yangtze River for water. Nor is it good news for the wild range of fish and wildlife that live in o r along the river.Many people have recognized the importance of protecting the Yangtze River, and organizations and projects have been set up to deal with the problem. The Green River organization, for example, educates people on the importance of protecting this great river. It also watches the river and stops the illegal hunting of animals, which has put the wild animal population in danger.Two special government projects are also under way. The first project, a water and soil conservation project, was set up in 1989. This project resulted in farmers replacing their crops with trees or grass. It has already been a success because it has helped improve the local environment and the land around the river.The second project includes nature reserves for white-flag dolphins, one of the rarest animals in the world. The number of white-flag dolphins in China has dropped because of pollution in the Yangtze River. The white-flag dolphin was last seen several years ago, though scientists are still hopeful that the animal has survived.We still have a long way to go to solve all the problems in regard to the Yangtze River. However, people have finally realized that it is their responsibility to protect this great river. Because of this, the situation on the Yangtze River is improving. TProject 2: Climate change and a low-carbon life There is no doubt that the world climate has been changing in recent years. Many people blame this change on gases such as carbon dioxide. Animals and humans produce carbon dioxide when they breathe. However, many other human activities also let off carbon gases. Anytime something is burnt, carbon is put into the atmosphere. Cars and other vehicles burn petrol in their engines, and electrical power plants most often burn fuels such as coal and oil in order to produce electricity. Therefore, the more petrol and electricity we consume, the more carbon we are letting off.One thing we can all do to help solve this problem is to walk or use a bicycle when possible. Although we produce carbon when we breathe, the carbon we produce is mu c h less than that produced by a car. Of course, there are times when we need to travel long distances. In this case, public transport such as buses and the underground are always much better choices than a private car or a taxi. If you must drive a car, it is never good to travel alone—you should try to findother people to travel with you.At home, you should use as little energy as possible. Turn off the lights and anything else electrical when not in use. Since factories use a lot of energy and also let off carbon gases, it is important to recycle as much as possible. In particular, metal products and paper p roducts require a lot of energy to produce, so you should find ways to use these again without throwing them away.te change.Step 1: Read and learn◆ Listen to the text and grasp the general spirit of the textLanguage focus:◆ 1. range n. （在一定范围或幅度内）变动，变化知识探究：(1) It is beyond the range (范范) of my ability.(2) It will encou rage a greater range (种类) of animals—all of which will make life for human beings better.(3) The range (幅度) of prices was great.(4) I ranged (排列)the books on the shelf by their authors.(5) He ranges (位居) among the great poets.题练落实：A) 1.

Unit 2 The environment【美文阅读】人类的贪婪是环境恶化的主要原因。

然而，除此之外还有其他因素吗？Is our environment being destroyed by greed?The environment has been suffering from all forms of damage；especially in recent years global warming seems to be the main problem.Many times，environmental worsening，in the form of running out of natural resources，and air，water and land pollution，is caused by the irresponsible behavior of humans.Nations，like the United States，set themselves above the ruin and damage of the environment.However，it will be unfair to state that environmental worsening is brought about only by greed.Other factors，such as the inability of some developing countries to find other choices of survival，also play a part in contributing to environmental problem.The state of the environment has been the concern of scientists in recent years.In the case of global warming，greed，in the sense of economic benefits of a country，actually contributes to the ruin of the environment.This is seen in the case of the United States' refusal to carry out its agreement to the Kyoto Protocol(京都议定书)，where countries come together and help deal with the increasing emission of greenhouse gases.If the US agreed to it，it would mean that it has to cut back on its Gross Domestic Product(GDP)growth.Another reason for environmental worsening is thatsome developing countries have few or no other choicesto making money for their survival.For example，slash­and­burn(刀耕火种)is the cheapest way for poor farmers even though it creates a serious environmental problem.Should they not practice slash­and­burn，they may not be able to clear the land in time for agricultural activities to support themselves and their family members.For them，environment concerns are secondary as compared to their survival.Therefore，to save the environment，everyone，be it young or old，rich or poor，should play a part in protecting the earth，as a collective effort definitely makes a big difference.【诱思导学】1．What are the forms of environmental worsening according to the passage?________________________________________________________________________ 2．Why does America refuse the Kyoto Protocol?________________________________________________________________________ 3．What causes the worsening of the environment?________________________________________________________________________ 【答案】 1.①Global warming②Running out of natural resources③Air，water and land pollution2．Because it will damage America's economic development.or：Because it means the US will have to cut back on its GDP growth.3．Human being's greed and their inability to find other choices of survival.Period ⅠPreviewing(教师用书独具)●教学目标本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，对下一堂课中课文的全面理解起到一个铺垫作用。
