OG 12 SC 80题

frankiyian

A report by the American Academy for the Advancement of Science has concluded that much of the currently uncontrolled dioxins to which North Americans are exposed comes from the incineration of wastes.

ABC 可数名词不用much排除了
D many of the dioxins that are currently uncontrolled and that North Americans are exposed to come
E many of the currently uncontrolled dioxins to which North Americans are exposed come

正确选项是e，我看了OG的解答之后能明白that are多余，也能理解and前后不平行。
但是E选项里面的to which我不太了解。另这句话的逻辑关系也看不懂。。。
A report。。。concluded that 。。。dioxins come from incineration。
望大牛解答

to which ..... exposed .... , exposed to 是固定用法，只是用在which从句的时候，把to提前了

逻辑关系不知道你那里不懂了

哦，那意思就是to which。。。 are exposed就是dioxins expose to N.A 的被动写法，which从句描述这些many of dioxins就是那些北美人民暴露于其中的

句意是 报告被xx机构总结that。很多那些（北美人民暴露于其中）的dioxins是由垃圾燃烧产生的

是这样的吗？？这两天做题做的头晕眼花的- -思维能力大幅度下降
