标题: 老prep 124求解

124. (31091-!-item-!-188;#058&004372)

Whereas the use of syntheticfertilizers has greatly expanded agricultural productivity in many parts of theworld, an increase in their use can create serious environmental problemssuch as water pollution, and their substitution for more traditionalfertilizers may accelerate soil structure deterioration and soil erosion. A

(A) an increase in their use cancreate serious environmental problems such as water pollution, and theirsubstitution for more traditional fertilizers

(B) an increase in their use cancreate serious environmental problems like water pollution, and if substitutedfor more traditional fertilizers, it

(C) if these fertilizers are usedincreasingly, they can create serious environmental problems such as waterpollution, and if used as substitutions for more traditional fertilizers, they

(D) the increased usage of thesefertilizers can create serious environmental problems such as water pollution,while if substituted for more traditional fertilizers, this substitution

(E) the increased usage of thesefertilizers can create serious environmental problems like water pollution,while their substitution for more traditional fertilizers

主要想问，their的指代问题。为什么可以指代fertilizers？fertilizers不是use的修饰语吗？代词不是只能指代中心词不能指代修饰语吗？这里不是还有parts of the world么，their语法上也能指代吧？这样不就指代不清了吗?

就是觉得这个their有问题，所以一开始就排除掉了ABC，最后选了C，但是答案是A。求NN解释，谢谢！

这题用平行解

whereas是表比较的，后面结构尽量平行对称

CD的前辈在prep2008里总结过：

如果whereas后面接介词短语，那么主句的开头也必须需要是介词短语(whereas后出现介词短语或者状语都会非常对称)，如果whereas后接单纯主谓宾（或主系表），主句也要尽量用单纯的主谓宾（或主系表）来对应

遵循了平行原则，你所担心的只带不明了问题就米有了
