||1:After a campaign by a green group called ForestEthics, Chiquita agree d in November to avoid fuel from Canadian tar sands.||2:Extracting this oil is a dirty process.||3:Environmentalists have worked furiously to block a pipeline, called Keystone XL, which would carry it from Canada to America.||4:Chiquita told ForestEthics that it does not use such fuel in its ships and agreed to avoid its use in lorries.

||1:环保组织“森林伦理”(ForestEthics)发起环保运动后，奇基塔公司11月承诺不再从加拿大焦油砂中提取燃油。||2:提取这种燃油是一个污染环境的过程。||3:环保人士竭力阻止加拿大通往美国的Keystone XL输油管道的修建。||4:奇基塔公司告诉环保组织“森林伦理”(ForestEthics)，在其船运中他们不再使用这种燃油，同时也避免将这种燃油使用于陆运。

||Keystone XL makes environmentalists livid: many of them protested, inflating an enormous black plastic pipeline on Ms Landrieu’s lawn in Washington.|| Oil extracted from Canada’s tar sands produces about 17% more carbon dioxide than conventionally-pumped supplies do—largely thanks to the energy needed to get it out of the ground. The process uproots forests and leaves toxic lakes behind. A pipeline carrying Canadian oil to Gulf coast refineries would lower the cost of getting such oil to market, so it might encourage energy firms to extract more.

||1:基石工程让这些环保人士言论风生，他们中的很多人都反对铺设一条巨型黑色的塑料输油管道，穿过兰德里在华盛顿的草地。||||2:从加拿大油砂中提炼石油排放的二氧化碳比传统输油要多17%，这在很大程度上是因为油砂挖取需要能量。||3:但铺设管道将加拿大的石油运送到墨西哥湾海岸进行提纯将降低石油进入市场的费用，各种能源公司开采石油也会更加奋发有力。

||1:Mr McConnell may attach things that the president would rather avoid to proposals with broad support.||2:Approval of the Keystone XL pipeline, which would carry crude oil from Canada’s tar sands to refineries on the Gulf coast, fits this description.||3:But no compromise seems likely over global warming.||4:The president wants to do something about it, as his tentative deal with China this week shows (see article).||5:Most Republicans do not; Mr McConnell campaigned partly on rescuing his state’s coal mines from federal bullying.

||1:麦康奈尔先生也许会偏好总统避而远之而有支持率高的议案。||2:基斯顿输油管发展计划的批准符合麦康奈尔的口味，这项计划将加拿大焦油砂的原油运输到墨西哥区域的精炼厂。||3:但是一旦涉及全球变暖问题，似乎无法做出任何让步。||4:总统对此有所想法，因为他本周与中国达成临时协议（见文章）。||5:大部分共和党人不想如此；麦康奈尔先生竞选的部分理由是从联邦的欺凌下挽救他所在州的煤矿。
