80. A report by the American Academy for the Advancement of Science has concluded that much of the current uncontrolled dioxins to which North Americans are exposed comes from the incineration wastes.
正确答案 (E)many of the currently uncontrolled dioxins to which North Americans are exposed come
谁能帮我回答一下，这里为什么要用to which? 它指定是什么？

be exposed to

哦～～～～
对对对，这是个被动语态，秀逗了！
如果我改成many of the currently uncontrolled dioxins that are exposed by north americans come可以吗？
我觉得这样更清楚明了

仔细想了想反而晕了

等下，我忽然觉得to which中的 which,不是指be exposed to，而是指the currently uncontrolled dioxins
想想好像又不对，有谁能详细分析下句子啊？

dioxins which North Americans are exposed to comes from the incineration wastes.
等于
dioxins to which North Americans are exposed comes from the incineration wastes.
which是修饰dioxins

终于就明白了
谢谢

我想问B选项里的(B) much of the currently uncontrolled dioxins that
North Americans are exposed to come

用that其实也是可以的吧
