   11. But science does provide us with the best available guide to the future,and it is critical that our nation and the world base important policies on the best judgments 1 that science can provide concerning the future consequences of present actions.


  【分析】并列多重复合句。and连接两个并列分句。前一分句的主干为science...provide us with…guide,其中does对谓语起强调作用,to the future是宾语guide的后置定语。后一分句的主干为it is critical that...,其中it为形式主语,真正主语是that引导的主语从句,其主干为our nation and the world base important policies on...judgments。 judgments 后接两个定语结构:that引导的定语从句和介词短语concerning...。因critical表示“重要的”,主语从句使用了虚拟语气,动词base前省略了should。
  【译文】但是科学确实为我们的未来提供了最好的指导,关键是我们的国家和其他国家在做重要决策时,应该以科学能够提供给我们最好判断作为依据,这些判断涉及人类现在的行为对未来的影响。
  12 . Just as on smoking, voices now come from many quarters insisting that the science about global warming is incomplete, that it's OK to keep pouring fumes 2 into the air until we know for sure.
  【分析】多重复合句。句子主干为:voices...come from many quarters。句首just as…作比较状语,意为“正如···”。现在分词结构insisting...作voices的后置定语,其中包含两个由that引导的宾语从句,第二个宾语从句中it作形式主语,真正主语由不定式短语充当,从句until we know for sure 作时间状语。
  【译文】就像吸烟问题一样,现在来自许多领域的意见坚持认为有关全球变暖的科学还不完整,在我们证实这件亊之前可以向大气中不断地排放气体。
