问题 Contrary to earlier conjectures, it may be that increased atmospheric carbon dioxide as a result of burning fossil fuels would cool the globe by reducing the amount of solar energy absorbed by snow.

选项 A、increased atmospheric carbon dioxide as a result of burning
B、increased atmospheric carbon dioxide resulting from the combustion of
C、increasing carbon dioxide in the atmosphere resulting from the combustion of
D、carbon dioxide in the atmosphere that increased from burning
E、atmospheric carbon dioxide that increased from burning

答案B

解析 题意是由于化石燃料的燃烧而增加的大气中的CO2会通过减少雪吸收的太阳能量而降低全球温度。A中as a result of使用不妥,因为该词组总是作为状语来修饰整个句子的,而不能修饰一个名词,此处修饰dioxide是不对的;接着通过B、C的提示,我们发现B、C用combustion代替burning。刚才我们已提过,前者指结果,而后者指动作。那么,究竟是“燃烧这个动作导致了CO2的增加”呢?还是“燃烧后的结果导致了CO2的增加”呢?对比后,我们觉得后者是合乎逻辑的。由于确定了用combustion代替burning,则A、D、E均为错;B、C用resulting from代替了as a result of,改正了此处错误。B、C中最大的区别在于是用过去分词increased还是increasing修饰CO2,我们知道,现在分词表示主动、持续的动作,而过去分词作定语表示被动、完成的动作。在本句中,CO2后的resulting from已充分表明increase是被动动作,因而我们选B不选C。另外,C中把原句的atmospheric改为后置的in the atmosphere修饰,是不简洁的,B中的increased和atmospheric共同修饰CO2是很简洁的表达方式。
