1Even as we humans count on forests to soak up a good share of the carbon dioxide we produce, we are threatening their ability to do so.

主干主语:we;谓语:are threatening;宾语:their ability to do so

结构Even as引导让步状语从句,主句为we are threatening...。从句中count on forests to soak up...为不定式作宾补;the carbon dioxide后接省略关系代词的定语从句we produce。do so指代soak up carbon dioxide,避免重复。

译文尽管我们人类指望森林吸收我们排放的相当一部分二氧化碳,我们却正在威胁它们这样做的能力。

考点even as引导让步状语从句,相当于although · do so替代前文动词短语以避免重复

2Helping forests flourish as valuable “carbon sinks” long into the future may require reducing their capacity to absorb carbon now.

主干主语:Helping forests flourish...;谓语:may require;宾语:reducing their capacity...

结构动名词短语Helping forests flourish...作主语,as valuable “carbon sinks”为方式状语,long into the future为时间状语。谓语may require后接动名词reducing作宾语,their capacity后接不定式to absorb carbon作定语。

译文要让森林在遥远的未来继续作为宝贵的“碳汇”蓬勃生长,或许需要现在就降低它们吸收碳的能力。

考点动名词短语作主语 · require后接动名词作宾语

3The strategy also aims to ensure that carbon in woody material removed from the forests is locked away in the form of solid lumber or burned as biofuel in vehicles that would otherwise run on fossil fuels.

主干主语:The strategy;谓语:aims to ensure;宾语从句:that carbon...is locked away or burned

结构aims to ensure后接that引导的宾语从句。从句主语carbon后有介词短语in woody material及过去分词短语removed from the forests作后置定语。谓语为is locked away...or burned...并列结构。vehicles后接定语从句that would otherwise run on fossil fuels。

译文该策略还旨在确保从森林中清除的木质材料里的碳,以实木形式封存,或作为生物燃料在本会使用化石燃料的车辆中燃烧。

考点that引导宾语从句 · 过去分词短语作后置定语 · otherwise表示虚拟对比

4Only recently have they come to see the vital part forests will have to play in storing carbon.

主干主语:they;谓语:have come to see;宾语:the vital part

结构Only recently置于句首引起部分倒装,助动词have提前。the vital part后接省略关系代词的定语从句forests will have to play,in storing carbon为介词短语作状语。come to see表示逐渐认识到。

译文直到最近,他们才开始认识到森林在储存碳方面必须发挥的关键作用。

考点only+时间状语置于句首引起部分倒装 · 定语从句省略关系代词that/which
