2019-2020年高中英語 Unit 2 The environment教案 牛津譯林版必修5 【美文閱讀】 人類的貪婪是環(huán)境惡化的主要原因。然而，除此之外還有其他因素嗎？ 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(京都議定書)，where countries e 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 that some developing countries have few or no other choices to making money for their survival.For example，slashandburn(刀耕火種)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 pared 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. 【誘思導(dǎo)學(xué)】 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 warming?、赗unning out of natural resources?、跘ir，water and land pollution 2．Because it will damage Americas economic development. or：Because it means the US will have to cut back on its GDP growth. 3．Human beings greed and their inability to find other choices of survival.
