(A) much of the currently uncontrolled dioxins to which North Americans are exposed comes (B) much of the currently uncontrolled dioxins that North Americans are exposed to come (C) much of the doxins that are currently uncontrolled and that North Americans are exposed to comes (D) many of the dioxins that are currently uncontrolled and North Americans are exposed to come (E) many of the currently uncontrolled dioxins to which North Americans are exposed to come 请问各位NN，D选项的解释是to maintain the parallel in this construction,that would have to be repeated in the clause that North Americans are exposed to.我想问的是，这个句子的平行结构是什么与什么平行啊？我怎么都没有看明白。而且，这个that是被怎么替代的呢？谢谢啦~作者: qingbo 时间: 2010-9-12 17:32
