高二英语Module 5 Unit 2 environment 译林版【本讲教育信息】一. 教学内容：Module 5 Unit 2 environment二. 教学目标：Unit 2 Reading, Language Points三. 教学重难点：Language Points〔一〕ReadingReading strategy: reading a debateIn a debate, one side gets the opportunity to present their points first. The other side follows and presents theirs. In an actual debate, there is often a discussion after both sides have presented their views.Speakers in a debate will represent opposite views on the subject being discussed. You may find that you agree with some points made by one debater, and some points made by the other. This is fine. In fact, most people find themselves ‘in the middle’ on many difficult issues.While reading or listening to a debate, remember that each speaker’s speech is meant to convince you. If the speakers are good debaters, you will find yourself agreeing with both of them. Just keep in mind that you should not make a final decision until you have read or listened to both sides completely and understood all of the arguments made by each side.〔二〕Language Points1. comment:〔1〕N. [C or U] something that you say or write that expresses your opinion：评论，观点。

Unit 2 The environmentIs our environment being destroyed by greed?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？The environment has been suffering from all forms of damage，especially in recent years global warming seems to be the main problem.Many times，the worsening of the environment，in the forms of running out of natural resources, and air，water and land pollution，is caused by the irresponsible behaviour of man.However，it will be unfair to state that the worsening of the environment 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 problems.The state of the environment has been the concern of scientists in recent years.As for global warming，greed，in order to get economic benefits, actually contributes to the ruin of the environment.This is seen when the United States refused to carry out its agreement to the Kyoto Protocol (《京都议定书》), which helps deal with the increasing emission of greenhouse gases.If the USA had agreed to it, it would have meant that it had to cut back on its Gross Domestic Product(GDP) growth.Another reason for the worsening of theenvironment is that some developing countries have nochoice but to survive at the cost of theenvironment.For example, slash­and­burn agricultureis the cheapest way for poor farmers even though itcreates a serious environmental problem.If they don'tdo that，they may not be able to clear the land in time for agricultural activities to support themselves and their family members.For them, pared to their survival, environment concerns are secondary.Therefore, to save the environment, everyone, young or old, rich or poor, should play a part, as a collective effort definitely makes a big difference.[阅读障碍词]1．irresponsible adj. 不负责任的2．inability n. 无能3．survival n. 生存，幸存4．theKyotoProtocol《京都议定书》5．slash­and­burn adj.刀耕火种的6．definitely adv. 肯定地[诱思导读]阅读短文，回答下列问题。
