问题 The government can take a variety of actions to help protect the environment. Which one of the following do you think is the most important for the nation’s government to take to protect the environment?
. Fund research to develop environmentally friendly energy sources such as solar and wind energy.
. Preserve natural places like forests and protect the animals that live there.
. Enforce laws to prevent the pollution of air and water by large companies.
Use specific reasons and examples to support your answer. Be sure to use your own words. Do not use memorized examples.

答案 The three measures of protecting the environment listed above are all significant. But I think the first one is of upmost importance as it provides a sustainable solution to the major environmental problems presented today. To protect the environment, we should realize and acknowledge that human activities are the major cause of the most severe environmental crisis that is going on: global warming. Therefore, the most important measure to protect the environment should be the one that helps address this issue. The other two measures, though indispensable and having been carried out for a long time, they do not go straight to the heart of the matter—global warming. Funding research to develop environmentally friendly energy, such as solar and wind energy, will be conducive to reducing the use of fossil fuels, which causes the majority of carbon dioxide emissions and leads to global warming. With the rise of temperature, the sea level is rising at a growing speed annually, affecting the people living in coastal areas. More places in the world have already witnessed an increasing number of extreme weather incidents. Developing alternative energy, which does not result in CO2 emission, thus shows great potential to slow the speed of global warming. Developing clean energy will also change the public’s attitudes towards the resources on earth. People will start, to realize that the resources on earth are limited and we should not run out of them. By using more clean energy, we are giving back space, land and resources to other life that inhabits the earth. This will thus help better protect the forests, lakes and animals, as suggested in the second measure in the question. It is a trend for countries to develop new energy and many achievements have been made. Now we have witnessed an increasingly large number of applications of clean energy such as solar panel boilers and electric cars. I believe that more new inventions are yet to come. While the other two measures proposed in the question have been implemented for years without making significant breakthroughs, new energy will be a game changer in the course of environmental protection.
解析     第1段：引入话题，表明选择。提出主题，做出自己的选择：选择资助研究以开发如太阳能和风能等环境友好型能源这项措施。
    第2段：总体说明原因。结合当今全球变暖的大背景，提出本文对于好的措施的定义，结合这一定义，否定了其他两项措施，并自然地衔接了下文。读者会期待下文阐述所选措施如何满足给出的定义。
    第3段：给出第一个理由。主题句论证化石燃料的使用最终引起全球变暖。举例说明全球变暖带来的不良影响，说明开发风能、太阳能对于缓解全球变暖的意义。
    第4段：说明第二个理由。主题句提出开发清洁能源将改变公众对地球资源的态度，具体说明这种改变是什么。呼应了题干的保护森林等自然环境和自然界中的动物这项措施，解释人类使用清洁能源对节能环保的有利影响，使文章面面俱到，不失偏颇。
    第5段：阐述第三个理由。列举新能源取得的成果和应用，表示期待新能源的后续开发。再次比较三项措施，突出所选措施为什么是最重要的。
