结构推理 At an international convention in Brussels organized by environmental groups,representatives from attending nations denounced the water privatization policies followed by the World Bank and the World Trade Organization.
They felt this(water privatization)is clearly against the spirit contained in Principles 2 and 12 of the Rio Declaration on Environment and Development signed in 1992.Part of the Declaration says,States should cooperate to promote a supportive and open international economic system that would lead to economic growth,and sustainable development in all countries,to better address the problems of environmental degradation.

【正确答案】在布鲁塞尔召开的由环境组织发起的一次国际会议上，与会国家的代表谴责了世界银行及世界贸易组织遵循的水源私有化政策。
他们认为，这(水源私有化)明显与1992年签署的《里约热内卢环境和发展宣言》中的第2条和第12条的精神相抵触。《宣言》的部分内容是这样的：“各国之间应相互合作，致力于建立一个相互支持、开放性的国际经济体制。这一体制会促进所有国家经济增长和可持续发展，更好地处理环境恶化问题。”

【答案解析】本文是关于因水而引起的世界纷争方面的文章。原文中第二句中against的意思是“抵触”，而不是“反对”的意思。“与……相抵触”是属于政论体的专业术语。在对states should cooperate to promote a supportive and open international economic system这一句的翻译中，为平衡句子，使之更加连贯，符合汉语习惯，译文把定语从句that would lead to economic growth，and sustainable development in all countries．to better address the problems of environmental degradation分开翻译，断句合理，语气顺畅。
