问题     The work on atmospheric chlorofluorocarbons (氯氟化碳) led eventually to a global CFC ban that saved us from ozone-layer reduction. Do we have time to do a similar thing with carbon emissions to save ourselves from climate change?
    Not a hope at all. Most of the "green" stuff is very close to a big trick. Carbon trading, with its huge government grants, is just what finance and industry wanted. It’s not going to do a thing about climate change, but it’ll make a lot of money for a lot of people and postpone the moment of reckoning.
    I am not against renewable energy, but to spoil all the decent countryside in the UK with wind farms is driving me mad. It’s absolutely unnecessary, and it takes 2,500 square kilometers to produce a gigawatt (十亿瓦特) — that’s an awful lot of countryside.
    Work to sequester (隔离) CO2 (carbon dioxide) is also a waste of time. It’s a crazy idea — and dangerous. It would take so long and use so much energy that it will not be done.
    And, nuclear power is a way for the UK to solve its energy problems, but it is not a global cure for climate change. It is too late for emissions reduction measures.
    Yet we are not doomed. There is one way we could save ourselves and that is through the massive burial of charcoal (木炭). It would mean farmers turning all their agricultural waste — which contains carbon that the plants have spent the summer sequestering — into charcoal, and burying it in the soil. Then you can start shifting vast quantities of carbon out of the system and pull the CO2 down quite fast.
    What we can do is getting farmers to burn their crop waste at very low oxygen levels to turn it into charcoal, which the farmer then ploughs into the field. A little CO2 is released but the bulk of it gets converted to carbon. You get a few per cent of bio-fuel as an additional product of the burning process, which the farmer can sell. This scheme would need no subsidy (补贴): the farmer would make a profit. This is the one thing we can do that will make a difference.
To reduce carbon emission fast in the world, the author suggests______.
选项 A、capturing and sequestering CO2 in the air
B、building more nuclear power plants
C、planting more trees to absorb CO2
D、burying burnt crop waste into the field
答案D
解析 根据题干中的reduce carbon emission fast将本题出处定位到第六段。该段第三句提到作者所建议的减少碳排放量的具体做法：农民将他们的农业废弃物转化为木炭，然后埋入土壤中。末句提到这样做的效果：大量减少大气中的碳，并快速降低二氧化碳量。第七段首句提到如何将农业废弃物转化为木炭：让农民在低氧状态下燃烧农作物尾料，将其转变为木炭。由此可知，为了快速减少世界上的碳排放量，作者建议把燃烧过的农业废弃物埋入土壤，故答案为[D]。[A]与第四段首句矛盾，故排除；[B]可由上题解析排除；[C]在文中未提及。
