新prep1-233 (GWD-12-Q32)，请教

独眼豆豆

以下是引用cuishang11在2009/5/26 1:43:00的发言：

A、B、C皆错在句子重心问题  “ Prospecting for gold during the California gold rush was a relatively easy task” 的原因不是"erosion, prehistoric glacier movement, and ancient, gold-bearing riverbeds "这三个名词  而应该是“erosion, prehistoric glacier movement, and ancient, gold-bearing riverbeds put gold literally within reach of anybody with a pan or shovel.”这句话

只有E完整地表述了原因

说滴太好啦！

 我认为： A B选项的because of错误，后面不能接抽象名词

        而C D中的erosion, prehistoric glacier movement, and volcanic activity that thrust ancient, gold-bearing riverbeds to the surface        erosion,prehistoric glacier movement这2个名词不与volcanic activity 后面再接一个从句平行

   请NN指教

E 无比正确，一般来说，如果能够用过去完成时（trust。。。）修饰N.的话就不用定语从句修饰。这是GMAT喜欢的简洁形式。如intended to等,是很好很强大的解题点。

thrust 过去分词短语做后置定语，容易看不清楚。

弱问下：reach of 和reach for 有什么区别？

10楼说的很有道理 但是E中是不是如果把volcanic activity提前就更加符合平行原则了呢？

可是我觉的erosion，prehistoric glacier movement, 和volcanic activity 是相似的应该并列啊，

the structure of the clause:
subject: erosion,prehistoric glacier movement,and ancient, gold -bearing riverbeds
            ancient, gold-bearing both modify riverbeds
            thrust to the surface by volcanic activity modifies riverbeds too
verb:put
